In this case, the window transmittance is adjusted to a specified value (less than the specified value) in a specific area, so that it does not violate laws and regulations such as vehicle transport safety standards and stays in a legal state while falling asleep. Can be effectively suppressed.

  (5) The invention according to claim 5 includes a biosensor for detecting a biometric data value of the driver, and an identification means for identifying the driver based on a detection result of the biosensor, wherein the control means The same driver identified by the identifying means is controlled based on the dozing history.

  That is, the driver is identified based on the detection result of the biosensor, and a history of determination results of the dozing determination unit at the time of starting the engine is accumulated for the same identified driver, so that the possibility of falling asleep is determined. Is greater than or equal to a predetermined number of times, it is determined that there is a possibility of falling asleep at the start of the engine, and when it is determined that the location of the vehicle belongs to a specific region, the transmittance of the light control glass is set to a predetermined value ( Although it is adjusted to less than the specified value), the engine is controlled not to start. In this case, the window transmittance is adjusted to a specified value (less than the specified value) in a specific area, so that it does not violate laws and regulations such as vehicle transport safety standards and stays in a legal state while falling asleep. Can be effectively suppressed.

  (6) In the invention described in claim 6, in the above (1) to (3), the light control glass is a liquid crystal layer that blocks visible light by changing the orientation of liquid crystal molecules by applying a predetermined voltage. A light control glass comprising a liquid crystal film sandwiched between two transparent electrodes, and the control means applying a predetermined voltage to the two transparent electrodes to change the orientation of the liquid crystal molecules. Is adjusted to be less than a predetermined value.

In other words, when a light control glass including a liquid crystal film is used, the transmittance of the light control glass can be easily set to a predetermined value (less than a specified value) by simply applying a predetermined voltage between the two transparent electrodes. ) To make the window glass in a high concentration state, making it unsuitable for running.

By controlling the state, arbitrary color development or arbitrary image display is executed in the organic electroluminescence element layer.

  In other words, when a light control glass containing an organic electroluminescence element layer is used, the transmittance of the light control glass can be very easily achieved simply by causing the light emitting layer of the organic electroluminescence element layer to emit light of a predetermined color. By switching to a predetermined value (less than the specified value), the window glass can be brought into a high concentration state. Also in this case, the light control glass including the organic electroluminescence element layer can be functioned as a display device for the outside as described later.

  (8) In the invention according to claim 8, the organic electroluminescence element of the light control glass used as the rear window glass of the vehicle when the dozing determination means determines that there is a possibility of falling asleep. Hazard lamp display is executed in the layer.

  Here, when the driver is in a drowsy state and cannot travel, the vehicle is stopped, and in the organic electroluminescence element layer of the light control glass used as the rear window glass, a display indicating the stopped state due to the dozing is performed. , It is possible to clearly tell other vehicles, pedestrians, etc. that the vehicle is stopped, and the safety during stopping can be improved.

  In addition, for example, by making the color of all window glasses the same as the outer surface of the vehicle while the vehicle is stopped, the appearance is stylish and extremely conspicuous, so that a malicious third party can illegally steal It becomes difficult to do the act, and it greatly contributes to the prevention of the illegal act against the vehicle.

  In addition, in the organic electroluminescence element layer of the light control glass used as the rear window glass during the movement of the vehicle, by executing the display linked to the brake operation of the vehicle and the display linked to the operation of the direction indicator of the vehicle, The large display using the rear window glass as well as the brake lamps and turn signals makes it possible to clearly communicate the driver's intention of braking and moving direction to the driver of the vehicle behind, and safety during traveling Can increase the sex.

  (9) In the invention of the vehicle control device related to the display, only when the vehicle location is determined to belong to the specific area and the vehicle moving speed is determined to be zero, the light control glass is transmitted. The rate is adjusted to less than a predetermined value and an image is displayed according to the audio signal. On the other hand, when it is determined that the vehicle location does not belong to the specific area, or the vehicle moving speed is not zero. In such a case, the transmittance of the light control glass is adjusted to a predetermined value or higher and no image is displayed on the glass.

Therefore, when a vehicle or the like as a vehicle is stopped on a public road or is moving even if it is not on a public road, the transmittance of the window glass (light control glass) is switched to less than a predetermined value or an image is displayed. In other words, since the window glass cannot be switched to an opaque state, safety during stopping on public roads and safety during movement in areas other than public roads can be ensured.

  That is, only when it is determined that the location of the vehicle belongs to the specific area and the moving speed of the vehicle is zero, the light control glass can function as a display device for the outside as described later. It becomes possible.

  Therefore, the effect display according to the audio signal such as car audio is displayed on the glass, so that it is possible to inform the surroundings that the vehicle is stopped and that the vehicle is in a state where it cannot enjoy traveling while enjoying music. .

  (10) In the invention according to claim 9, at the time of starting the engine, it is determined by the dozing determination means that the driver may fall asleep, and the position determination means determines that the location of the vehicle belongs to a specific region. In this case, the transmittance of the light control glass of the window is adjusted to a predetermined value (less than the specified value), and the engine is started.

  That is, according to this vehicle control device, when it is determined that there is a possibility of falling asleep when the vehicle engine is started, the transmittance of the light control glass is adjusted to a predetermined value (less than a specified value). Therefore, if the driver of the vehicle has a possibility of falling asleep, the transmittance of the window glass (light control glass) becomes a predetermined value (less than the specified value), which is not suitable for traveling.

  On the other hand, since the start of the engine is not limited, air conditioning or the like can be used. That is, although the engine can be started and used for cooling and heating, it is not suitable for traveling, so it is possible to effectively suppress the drowsy driving without giving the passengers discomfort in the vehicle. Furthermore, since this control is executed at the time of starting, the vehicle cannot be moved from the parked / stopped position, and it is possible to effectively suppress the drowsy driving. In addition, privacy and security are ensured.

  In addition, because it adjusts the window transmittance to a predetermined value (less than the specified value) when it is in a specific area, it does not violate laws and regulations such as vehicle transportation safety standards, and it is possible to doze while driving in a legal state. It becomes possible to suppress effectively.

  (11) In recent years, by using the GPS function of a car navigation system that is generally installed in automobiles and the like, the location of the vehicle can be detected very easily without newly providing special position detection means. be able to.

  Further, according to the road transport vehicle safety standard (Article 29, Paragraph 4), at least the window glass in front and both sides of the driver is adjusted for transmittance according to the determination results of the position determination means and the speed determination means. The transmittance of the light control glass used as a window glass other than the target window glass may be less than a predetermined value regardless of whether the vehicle is stopped / moving or regardless of the location of the vehicle. By being configured to be selectively switchable to one of the above, it is possible to switch between transparent / high density at any time depending on the will of the vehicle occupant and the result of detection of snoozing for windows other than the target window glass. Yes, safety and convenience can be improved.

  (12) By limiting the upper limit of the engine speed to the idling state or the idling-up state when using the air conditioner after the vehicle belongs to a specific region and becomes zero speed when a doze is detected With the above-described increase in the concentration of the window, it is possible to further ensure the drowsy driving suppression.

(13) When dozing is detected, the vehicle belongs to a specific area and becomes zero speed.
In the case of an automatic vehicle, the shift is not performed electrically regardless of the shift operation, so that the concentration of the window can be increased and the drowsy driving can be more reliably suppressed.

  (14) When a drowsiness is detected, after the vehicle belongs to a specific region and the speed becomes zero, and when there is a shift operation in the case of an automatic vehicle, the transmission is controlled to be in the neutral state. As the concentration of the window is increased, it is possible to further ensure the drowsy driving suppression.

  Furthermore, by adjusting the transmittance of the light control glass according to the brightness of the outside of the vehicle, when the outside of the vehicle is dark, the transmittance can be increased and the field of view can be secured, while when the outside of the vehicle is extremely bright Can reduce the glare experienced by the driver and the occupant by reducing the transmittance, so that the driver can surely see the situation outside the vehicle, and the safety can be improved.

Embodiments of the present invention will be described below with reference to the drawings.
[1] Configuration of the vehicle control device of the present embodiment:

Here, the automobile 100 as a vehicle in this embodiment is a typical four-door type passenger car, and includes six window glasses 111 to 116 (front window glass 111, right front side window glass 112, left front side window). Glass 113, right rear side window glass 114, left rear side window glass 115 and rear window glass 116).

  As the light control glass 110 constituting these window glasses 111 to 116, the light control glass 110A as shown in FIG. 2, the light control glass 110B as shown in FIG. 3, or the light control glass as shown in FIG. Any of the glasses 110C can be used.

  Here, “light control glass” means that the visible light transmittance and coloring of the glass itself can be freely adjusted, so that the separated side of the glass can be visually recognized without using a curtain or a shutter. It is a glass that can be made impossible (high concentration state).

  The “glass” of the “light control glass” here is not limited to a material called glass mainly composed of silicon dioxide, but can be used for windows, etc. "Glass" in a broad sense that refers to a certain plate-like material, including materials such as plastics such as acrylic and polycarbonate.

  FIG. 2 is a cross-sectional view schematically showing the structure of a light control glass (first example) 110A. As shown in FIG. 2, the light control glass 110A is configured to be dimmable using liquid crystals. There is a structure that is normally transparent, but has a structure in which light is blocked by changing the orientation of liquid crystal molecules by applying a voltage.

More specifically, the light control glass 110 </ b> A is configured by sandwiching an organic electroluminescence element layer 140 between two glass plates (transparent plates) 120 and 130. Hereinafter, “electroluminescence” may be abbreviated as “EL”.

  The organic EL element layer 140 is configured by sandwiching the organic EL layer 143 between the anode transparent electrode 141 and the cathode transparent electrode 142. The organic EL layer 143 emits light by applying a voltage between the anode transparent electrode 141 and the cathode transparent electrode 142.

  The organic EL layer 143 is formed by laminating three layers of a hole transport layer 144, a light emitting layer 145 and an electron transport layer 146 in order from the anode side, and between the anode transparent electrode 141 and the cathode transparent electrode 142. When voltage is applied, emitted light is emitted from the light emitting layer 146 toward the anode.

  The light-emitting layer 146 is configured by regularly arranging light emitters that emit red (R), green (G), and blue (B), which are the three primary colors of light, in a matrix. The configuration allows the light control glass 110A to function as a color display device.

  In the light control glass 110A, the display state by the organic EL element layer 140 (the light emission state of the three primary color light emitters) is controlled by the display control function and the dozing operation suppression control function of the adjusting means 10b described later, and is entirely the same color. In addition to the above color display, it is possible to display an arbitrary image and notify various information to the outside.

  In the present embodiment, the organic EL layer 143 includes three layers, ie, a hole transport layer 144, a light emitting layer 145, and an electron transport layer 146. However, the present invention is not limited to this, and a single layer is used. Or an organic EL layer, such as a layer composed of two layers of a hole transport layer and a light emitting layer.

  And in light control glass 110A, in order to adjust the transmittance | permeability of visible light, the liquid crystal film 150 is stuck on the vehicle interior side. Even if the liquid crystal film 150 is affixed to the vehicle interior side of the light control glass 110A, that is, the glass plate 130, light control (change / adjustment of visible light transmittance; described later) by the liquid crystal film 150 is performed. The display (described later) on the outside (outside the passenger compartment) by the layer 140 is not blocked by the liquid crystal film 150.

  The liquid crystal film 150 is configured by sandwiching transparent electrodes 153 and 154 and a liquid crystal layer (liquid crystal molecules) 155 between two transparent thin films 151 and 152. The liquid crystal layer 155 is sandwiched between the transparent electrodes 153 and 154.

  Then, by applying a predetermined voltage between the transparent electrodes 153 and 154, visible light is blocked by changing the orientation of liquid crystal molecules in the liquid crystal layer 155.

  In other words, the liquid crystal film 150, that is, the light control glass 110A is in a transparent state (a visible light transmittance is a predetermined value of 70% or more) without applying a voltage, but is high when a predetermined voltage is applied. It can be switched to a density state (a state where the visible light transmittance is less than a predetermined value of 70%). The voltage applied to the liquid crystal film 150 is adjusted and controlled by the adjusting means 10b described later.

As described above, by providing the organic EL element layer 140 and the liquid crystal film 150 in one dimming glass 110A, the organic EL element layer 140 functions as a color display device, and the general dimming by the liquid crystal film 150 is performed. Both glass functions can be realized. If the light control glass 110A is not intended for color display, it is not necessary to provide all three color light emitters of RGB.

  FIG. 3 is a cross-sectional view schematically showing the structure of the light control glass (second example) 110B. As shown in FIG. 3, the light control glass 110B is configured to be dimmable using a photochromic method, and is configured in substantially the same manner as the light control glass 110A shown in FIG. The glass 110B is provided with a photochromic glass layer 160 instead of the liquid crystal film 150 of the light control glass 110A. This photochromic glass layer 160 uses a substance that is colored by irradiating light of a specific wavelength, and is affixed to the outside of the light control glass 110B, that is, the glass plate 120. In FIG. 3, the same reference numerals as those already described indicate the same or substantially the same parts, and the description thereof will be omitted.

  More specifically, in the light control glass 110B, in order to adjust the transmittance of visible light, the photochromic glass layer 160 having a function of coloring the outside of the anode-side glass plate 120 by irradiation with light of a specific wavelength. Is provided. The photochromic glass layer 160, that is, the light control glass 110B is normally in a transparent state (a visible light transmittance of 70% or more, which is a predetermined value), but the organic EL layer 143 (light emitting layer 145) When light having a specific wavelength is emitted, it is colored and switched to a high concentration state (a state where the visible light transmittance is less than 70%, which is a predetermined value). Instruction and control for causing the organic EL layer 143 (light emitting layer 145) to emit light having the specific wavelength to color the photochromic glass layer 160 is performed by the adjusting unit 10b described later.

  At this time, in the light control glass 110B, the photochromic glass layer 160 is colored by specific ultraviolet light, and the light emitting layer 145 of the organic EL element layer 140 is red (R), green (G), blue (B). It is assumed that the three primary colors of light and four types of light emitters emitting the specific ultraviolet light are regularly arranged in a matrix. In this case, the light emission state of the ultraviolet light emitter is controlled by the adjusting means 10b described later, while the display state by the organic EL element layer 140 (light emission state of the three primary color light emitters) is the same as that of the light control glass 110A. Similarly, it is controlled by a display control function or a drowsy driving suppression control function of the adjusting means 10b described later, and not only can display the same color on the entire screen, but also displays an arbitrary image and provides various information to the outside. Can be notified.

  As described above, by providing the organic EL element layer 140 and the photochromic glass layer 160 in one light control glass 110B, the organic EL element layer 140 (for ultraviolet light) functions as a color display device. It is possible to realize both of the function as a light control glass by the cooperative operation of the light emitter and the photochromic glass layer 160. If the light control glass 110B is not intended for color display, it is not necessary to provide all of the three RGB light emitters, and the light for coloring the photochromic glass layer 160 is not limited to ultraviolet light. Infrared light or light having a wavelength different from that of display light during monochromatic display may be used, and light having a wavelength used when used as a display device may be used.

  FIG. 4 is a cross-sectional view schematically showing the structure of the light control glass (third example) 110C. As shown in FIG. 4, the light control glass 110C includes the liquid crystal film 150 of the light control glass 110A shown in FIG. It has a configuration equivalent to that obtained by removing the photochromic glass layer 160 of the light control glass 110B shown in FIG. Since the photochromic glass layer 160 is not provided, naturally, the ultraviolet light emitter in the organic EL element layer 140 described above for the light control glass 110B is also unnecessary. In FIG. 4, the same reference numerals as those already described indicate the same or substantially the same parts, and the description thereof is omitted.

  More specifically, in the light control glass 110C, the organic EL element layer 140 functions not only to perform color display but also to adjust the transmittance of visible light. That is, the organic EL element layer 140, that is, the light control glass 110C is normally in a transparent state (a visible light transmittance of 70% or more which is a predetermined value), but the organic EL layer 143 (light emitting layer 145). When light is emitted and some color display is performed, the state can be switched to a high density state (a state in which the transmittance of visible light is less than a predetermined value of 70%).

  At this time, the light emission control of the organic EL layer 143 for the purpose of increasing the concentration of the light control glass 110C is performed by the adjusting means 10b described later, while the purpose is to perform color display on the light control glass 110C. The light emission control of the organic EL layer 143 is performed by a display control function or a drowsy driving suppression control function of an adjusting unit 10b described later. Also in the light control glass 110C, the display state by the organic EL element layer 140 (the light emission state of the three primary color light emitters) is the same as the light control glasses 110A and 110B, and the display control function of the adjusting means 10b described later and the drowsy operation suppression. It is controlled by the control function and not only can display the same color on the entire surface, but also can display an arbitrary image and notify various information to the outside.

  As described above, by providing the organic EL element layer 140 in one dimming glass 110C, it is possible to realize both a function as a color display device and a function as a dimming glass. If the light control glass 110C is not intended for color display, it is not necessary to provide all of the three color light emitters of RGB.

[1-2] Configuration of the vehicle control apparatus 101 of the present embodiment:
In the automobile 100 according to the present embodiment shown in FIG. 1, the drive of the engine 40 is transmitted to an alternator (not shown), and power is generated by the alternator. The electric power is generated by an ordinary battery and the vehicle control apparatus 101 according to the present embodiment. Are stored in a dedicated battery (both not shown). Here, the normal battery is a power source for operating the ignition plug and various accessories of the engine 40, and the dedicated battery is a dedicated power source for operating the light control glass 110 according to the present embodiment. Thus, by separating the power source for operating other equipment and the power source for operating the light control glass 110, the light control glass 110 consumes power when the engine 40 is not operating. However, it is possible to prevent the battery for starting the engine 40 from rising.

  And the vehicle control apparatus 101 of this embodiment is connected to each of the light control glass 110 which comprises the six window glasses 111-116, and the transmittance | permeability of the visible light in each light control glass 110 is shown in FIG. The color display by the organic EL element layer 140 in each light control glass 110 is controlled, and various controls of the engine 40 are performed.

  That is, the vehicle control apparatus 101 includes a CPU 10 as a control unit, a GPS position detection unit 21 as a position detection unit, a speed sensor 22 as a speed detection unit, a lightness sensor 23 as a lightness detection unit, a storage unit including a ROM and a RAM. 30 is configured.

Here, the ROM (Read Only Memory) of the storage unit 30 is a program (light control program / display control program / drowsiness driving suppression program) to be executed by the CPU 10 to realize the function as the vehicle control device 101, Initial data (default values, etc.) required for executing these programs, and position determination conditions and speed determination conditions required for determination by position determination means 11, speed determination means 12, and doze determination means 14 described later, respectively. And doze determination conditions, area information (longitude / latitude information of a specific area described later) and speed information (information of zero speed described later), doze determination criteria information, and window glasses 111 to 116 necessary for the determination. Original displayed on the organic EL element layer 140 in each light control glass 110 It stores image data (in addition to brake display image data and direction indication display image data, which will be described later, and various display image data stored according to user preferences).

  The ROM of the storage unit 30 also stores a driver identification program necessary for the identification means 19. Further, the ROM of the storage unit 30 also stores an image pattern, a sound-image conversion program, and the like that are basic when effect display corresponding to the sound signal is performed on the glass.

  In the present embodiment, the position determination condition is that the location of the automobile 100 is a specific area designated in advance (more specifically, an area other than the public road on which the automobile 100 can travel; for example, private land or convenience store The speed determination condition is that the moving speed (vehicle speed) of the automobile 100 is zero.

  A RAM (Random Access Memory) of the storage unit 30 temporarily stores data (flags, variable values, etc.) used when the CPU 10 executes a program stored in the ROM, and also stores the window glasses 111 to 116. When color display is performed by the organic EL element layer 140 in each light control glass 110 to be formed, image data to be displayed by the organic EL element layer 140 is temporarily stored.

  In the present embodiment, the history of the doze determination result when the engine is started is stored in the RAM of the storage unit 30. In this case, it is desirable to identify the driver based on the detection result of the biosensor, and to accumulate a history of doze determination results at the time of starting the engine for the same identified driver. The RAM of the storage unit 30 also stores identification and collation templates, various data, and the like for driver identification required by the identification unit 19.

The GPS position detection unit 21 detects the location (current position; latitude / longitude information) of the automobile 100 using, for example, a GPS (Global Positioning System) function of an existing car navigation system. The speed sensor 22 detects the moving speed (vehicle speed) of the automobile 100, and the speed sensor 22 already used in the automobile 100 is also used. The lightness sensor 23 detects the lightness outside the vehicle 100 (the degree of brightness outside the passenger compartment; unit: lux (lx)).

  Further, various operation input units are connected to the vehicle control device 101, and an accelerator pedal 51, a brake pedal 52, a direction indicator operation unit 53, a changeover switch 54, a display instruction input unit 55, a dozing detection means 57, and driving. A biological sensor 59 for acquiring biological data for identifying a person is connected. Moreover, the display part 60 which receives the instruction | indication from the vehicle control apparatus 101 and performs various displays is provided. The display unit 60 can also be used as a display unit such as a speedometer or a display unit of a car navigation device.

The changeover switch 54 instructs the CPU 10 (adjusting means 10b described later) to instruct the dimming glass 110 to switch from the transparent state to the high concentration state or to switch the dimming glass 110 from the high concentration state to the transparent state. Instructions for switching all of the front window glass 111, the right front side window glass 112, the left front side window glass 113, the right rear side window glass 114, the left rear side window glass 115, and the rear window glass 116, An instruction to selectively switch at least one of the window glasses 111 to 116 can be given. Further, as will be described later, the changeover switch 54 can also set / cancel the brightness adjustment mode for adjusting the transmittance according to the detection result (brightness) by the brightness sensor 23.

  The display instruction input unit 55 gives an execution instruction or a release instruction for color display by the organic EL element layer 140 in each light control glass 110 to the CPU 10 (a display control function or a dozing operation suppression control function of the adjusting unit 10b described later). For example, the image to be displayed on each light control glass 110 is designated from the original image data stored in the ROM of the storage unit 30 and the display instruction or release instruction for the image is given. A color to be emitted from the light control glass 110 is designated and a display instruction or a release instruction is given according to the color, or a brake display image as described later with reference to FIG. Instructing to set or cancel the brake display mode to be displayed on the rear window glass 116 (light control glass 110), see FIG. A direction indication displayed image as described later while, in which or to direct the operation setting or cancellation of direction indication display mode for displaying in accordance with the direction indicator operation unit 53 operated by the driver.

  The dozing detection means 57 detects a driver's dozing or a state related to dozing, and the detection result of the dozing detection means 57 is determined by the dozing determination means 14. Then, the determination result of the dozing determination unit 14 (no sleep / occurrence of dozing) is transmitted to the adjusting unit 10b. Then, the dozing operation suppression program is executed by the adjusting means 10b and the engine controller 10a described later, and the dozing operation suppression control function works.

  For example, as shown in FIG. 15, the dozing detection unit 57 corresponds to a camera that can capture a driver's face as a moving image at any position near the driver's seat of the dashboard 59 </ b> A. It should be noted that the location of the camera can be modified such as on the sun visor, dashboard, A pillar, and near the center of the steering.

  The biosensor 59 for driver identification includes a camera for photographing a face and an iris as shown in FIG. 15, a sensor for scanning fingerprints and palm blood vessels, and a sensor for detecting components in exhaled breath (not shown). Or a microphone (not shown) for acquiring the driver's voiceprint can be provided on the dashboard D, the steering wheel 58, or the like.

  In addition, as the biosensor, a biosensor 59 ′ (not shown) that is always worn by the driver is used, and necessary information is transmitted from the biosensor 59 ′ by wireless or infrared data transfer to the CPU 10. Can also be obtained.

  In this embodiment, the state related to dozing includes the degree of opening of the eyes on the driver's face (expression), the length of response time of a predetermined action, the correct answer rate of answers to a predetermined question, and the like.

In this case, the dozing determination unit 14 makes the determination based on the degree of eye opening (h1 / w1, h2 / w2) included in the driver's face image as shown in FIG.
In this case, the horizontal white eye and the black eye in the center, which are arranged side by side within a predetermined range of the face outline, are recognized by pattern recognition, and the degree of eye opening (aspect ratio) is obtained. Make a decision.

It is also possible to take a picture of the driver from the side or from an oblique direction, and detect / determine doze based on the position or movement of the head or upper body.
In addition, the snoozing can be detected by meandering the traveling locus of the vehicle. In this case, the GPS position detecting unit 21, a steering operation angle sensor (not shown), and the like constitute the dozing detection means 57. Further, not only meandering but also a sudden steering operation at the time of falling asleep, which is different from a normal steering operation, can be used for the detection of falling asleep.

Furthermore, as will be described later, it is possible to detect doze by examining the driver's brain waves or detecting the driver's reflexes.
A CPU (Central Processing Unit) 10 reads and executes a dimming control program / display control program / drowsiness driving suppression program stored in the ROM of the storage unit 30, thereby executing position determination means 11 and speed determination means described later. 12. The functions of the engine controller 10a and the adjusting means 10b as the dozing operation suppression control function and the dozing operation suppression control function are performed.

  The position determination unit 11 determines whether the location of the automobile 100 (current position; latitude / longitude information) detected by the GPS position detection unit 21 satisfies the position determination condition stored in the ROM of the storage unit 30. That is, it is determined whether or not the vehicle belongs to a specific area (an area other than the public road on which the automobile 100 can travel; for example, private land or a convenience store parking lot). This position determination means 11 determines whether the latitude / longitude information of the location detected by the GPS position detection unit 21 belongs to the longitude / latitude information of a specific area registered in the ROM of the storage unit 30 in advance. This is done by determining whether or not.

  The speed determination unit 12 determines whether or not the moving speed (vehicle speed) of the automobile 100 detected by the speed sensor 22 satisfies the speed determination condition stored in the ROM of the storage unit 30, that is, is zero. This is a judgment.

The dozing determination unit 14 determines whether there is no dozing / occurs of dozing based on the detection result of the driver detected by the dozing detection unit 57, and transmits the determination result to the adjustment unit 10b.
Although the state is not a nap, the state before the nap may be detected by the nap detection means 57, so that it may be determined that there is no nap / attention to doze / the occurrence of a nap.

Based on the detection result of the biosensor 59, the identification unit 19 identifies the driver using various methods such as template matching, and transmits the identification result to the adjustment unit 10b.
The engine controller 10a controls the number of revolutions of the engine 40 based on the accelerator pedal 51, the brake pedal 52, and the like, and has a drowsy driving suppression control function together with the adjusting unit described later based on the determination result by the dozing determination unit 14 described above. Execute.

  As will be described later with reference to FIG. 7, the adjusting means 10 b determines the position of the window glasses 111 to 113 in front and on both sides of the driver according to the safety standard (Article 29, paragraph 4) of the road transport vehicle. While the transmission rate is to be adjusted according to the determination result of the means 11 and the speed determination means 12 and the switching instruction performed by the changeover switch 54, as described later with reference to FIG. The window glasses 114 to 116 are subjected to transmittance adjustment according to only the switching instruction given by the changeover switch 54.

  Moreover, the adjustment means 10b makes at least the window glasses 111 to 113, preferably the window glasses 111 to 116, objects of transmittance adjustment in accordance with the determination result of the dozing determination means 14 for dozing operation suppression control.

In other words, when the adjustment means 10b receives an instruction from the changeover switch 54 to switch each of the light control glasses 110 forming the window glasses 111 to 113 from the transparent state to the high density state, the position determination means 11 determines the location of the automobile 100 in a specific region. Only when it is determined that the moving speed of the automobile 100 is zero by the speed determination means 12, the transmittance of each of the light control glasses 110 constituting the window glasses 111 to 113 is less than a predetermined value ( For example, the light control glass 110 is switched from a transparent state to a high concentration state.

  As described above, even after each dimming glass 110 constituting the window glasses 111 to 113 is switched to the high concentration state, the detection by the GPS position detection unit 21 and the speed sensor 22 and the detection result are obtained at every predetermined control period. When the determination by the position determination unit 11 and the speed determination unit 12 is performed and the position determination unit 11 determines that the location of the automobile 100 does not belong to the specific region, or the speed determination unit 12 When it is determined that the moving speed is not zero, the adjusting unit 10b immediately adjusts the transmittance of each light control glass 110 forming the window glasses 111 to 113 to a predetermined value or more (for example, 70% or more), The light control glass 110 is switched from a high concentration state to a transparent state.

  Further, the adjusting means 10b gives an instruction to switch the light control glasses 110 constituting the window glasses 114 to 116 that are not subject to the safety standards (Article 29, paragraph 4) of the road transport vehicle from a transparent state to a high concentration state. When received from the changeover switch 54, the transmittance of each light control glass 110 is adjusted to be less than a predetermined value (for example, less than 70%) regardless of the determination results by the position determination means 11 and the speed determination means 12, and each light control glass 110 is adjusted. Is switched from the transparent state to the high density state.

  Further, when the adjusting unit 13 receives an instruction to switch the light control glasses 110 forming the window glasses 111 to 116 from the transparent state to the high concentration state, the adjustment unit 13 sets the transmittance of each light control glass 110 to a predetermined value or more (for example, 70%). The light control glass 110 is switched from the high density state to the transparent state.

  Further, the adjusting means 10b of the present embodiment responds to the brightness outside the vehicle 100 (the degree of brightness outside the passenger compartment) detected by the brightness sensor 23 when the brightness adjustment mode is set by the changeover switch 54. Thus, it also has a function of adjusting the transmittance of each light control glass 110. For example, when the brightness outside the automobile 100 is low (that is, when the outside of the vehicle is dark), the light control glass 110 is adjusted to increase the transmittance, while when the brightness outside the automobile 100 is high (that is, when the outside of the vehicle is bright), It adjusts so that the transmittance | permeability of each light control glass 110 may be made low.

  Further, even when an ignition key (not shown) is operated and an engine start instruction is generated, the engine controller 10a and the adjusting means 10b of the present embodiment are configured so that the driver's face image or Control is performed so that the engine cannot be started until the posture state is photographed and the detection result of the dozing detection unit 57 is determined by the dozing determination unit 14 and transmitted to the adjusting unit 10b.

  Then, the adjustment means 10b according to the present embodiment determines that the position of the vehicle belongs to the specific area by the position determination means and determines that the moving speed of the vehicle is zero by the speed determination means when it is determined that the drowsiness has occurred. It has a function of reducing the transmittance of each light control glass 110 until it is not suitable for driving after it is determined that there is.

  In other words, when the napping is detected and the determination unit 14 determines that the dozing is napping, the adjusting unit 10b changes the transmittance of each light control glass 110 from the transparent state if the vehicle location and moving speed satisfy the conditions. Switch to a high concentration state. In this case, the adjusting means 10b sets at least the window glasses 111 to 113, preferably the window glasses 111 to 116, as targets for adjusting the transmittance of high density. As a result, the vehicle cannot be driven in a state of falling asleep.

In addition, when each light control glass 110 is the light control glass 110A shown in FIG. 2, the adjustment means 10b applies a predetermined voltage to the two transparent electrodes 153 and 154 in the liquid crystal film 150, and the liquid crystal in the liquid crystal layer 155. By changing the molecular orientation, the transmittance of the light control glass 110 is adjusted to be less than a predetermined value. Moreover, when each light control glass 110 is the light control glass 110B shown in FIG. 3, the adjustment means 10b applies a predetermined voltage to the transparent electrodes 141 and 142 of the organic EL element layer 140, and the light emitting layer 145 has a specific wavelength. The transmittance of the light control glass 110 is adjusted to be less than a predetermined value by emitting the light (ultraviolet light in the present embodiment) and coloring the photochromic glass layer 160. Furthermore, when each light control glass 110 is the light control glass 110C shown in FIG. 4, the adjustment means 10b applies a predetermined voltage to the transparent electrodes 141 and 142 of the organic EL element layer 140, and the light emitting layer 145 has a predetermined color. The light transmittance of the light control glass 110 is adjusted to be less than a predetermined value by emitting the light.

  The display control function of the adjusting means 10b is to control the light emission state of each light emitter of the light emitting layer 145 of the organic EL element layer 140 in each light control glass 110, thereby allowing any color development or any color in the organic EL element layer 140. The image is displayed.

  In particular, the display control function of the adjusting means 10b according to the present embodiment is based on the road transport vehicle safety standard (Article 29, Paragraph 4), as described later with reference to FIG. When the execution instruction for the color display on the window glasses 111 to 113 is received from the display instruction input unit 55, the position determination unit 11 determines that the location of the automobile 100 belongs to the specific area and determines the speed. Only when the moving speed of the automobile 100 is determined to be zero by the means 12, the image designated by the display instruction input unit 55 on the organic EL element layer 140 of each light control glass 110 constituting the window glasses 111 to 113. Etc. are executed.

  The display control function of the adjusting means 10b is as follows when an execution instruction for color display on the window glasses 114 to 116 is received from the display instruction input unit 55, as will be described later with reference to FIGS. Without performing the determination as described above, the organic EL element layer 140 of each light control glass 110 constituting the window glasses 114 to 116 is immediately caused to execute color display such as an image designated by the display instruction input unit 55.

  Further, as will be described later with reference to FIG. 9, the display control function of the adjusting means 10 b is that when the brake display mode described above is set by the display instruction input unit 55 for the rear window glass 116, In the organic EL element layer 140 of the light control glass 110 used as the rear window glass 116 during traveling, a display linked to the operation of the brake pedal 52 by the driver of the automobile 100 is executed.

  When the brake display mode is set, for example, when the driver operates the brake pedal 52, the brake lamp is turned on, and at the same time, a brake display image (an image including “brake!”) As shown in FIG. Is displayed. The brake display image is not limited to the example shown in FIG.

  Similarly, as will be described later with reference to FIG. 9, the display control function of the adjusting means 10 b is applied to the automobile when the direction instruction display mode described above is set for the rear window glass 116 by the display instruction input unit 55. In the organic EL element layer 140 of the light control glass 110 that is used as the rear window glass 116 while the vehicle 100 is traveling, a display linked to the operation of the direction indicator operation unit 53 operated by the driver of the automobile 100 is executed. When the direction indication display mode is set, for example, when the driver operates the direction indicator operation unit 53, the turn signal corresponding to the indication direction is turned on, and at the same time, the direction indication as shown in FIG. Display image (image including a large right arrow in response to a right direction instruction) is displayed. The direction indication display image is not limited to the example shown in FIG.

  Similarly, the display control function of the adjusting means 10b is the same as that of the rear window glass 116 in the organic EL element layer 140 of the light control glass 110 that is used as the rear window glass 116 while the automobile 100 is traveling. For example, a hazard lamp display image (an image including a large right arrow and a left arrow) indicating an emergency stop as shown in FIG. 6B is displayed. Note that the image is not limited to the example shown in FIG. As a result, it becomes unsuitable to drive the vehicle in a dozing state.

In the above configuration, when the driver is not identified, it is not necessary to provide the biosensor 59 and the identifying means 19.

Next, the dimming control operation (the operation of the adjusting means 10b) of the vehicle control apparatus 101 of the present embodiment configured as described above will be described with reference to FIGS. 7 is a flowchart for explaining the dimming control operation (the dimming control operation for the front window glass 111 and the front side window glasses 112 and 113) of the vehicle control apparatus 101 of the present embodiment, and FIG. 8 is the present embodiment. 6 is a flowchart for explaining a dimming control operation (a dimming control operation for the rear side window glasses 114 and 115 and the rear window glass 116) of the vehicle control device 101.

  As described above, the CPU 10 (adjusting means 10b) operates in response to an instruction from the changeover switch 54, and is the target of the road transport vehicle safety standard (Article 29, Paragraph 4). As for the window glasses 111 to 113 on both sides, the dimming control of the dimming glass 110 is performed according to the flowchart shown in FIG. 7 (steps S11 to S20), while the other window glasses 114 to 116 are shown in FIG. The light control of the light control glass 110 is performed according to the flowchart shown (steps S21 to S25).

  As shown in FIG. 7, when the window glasses 111 to 113 are set in a transparent state (a state in which the visible light transmittance is equal to or higher than a predetermined value (70%)) (YES route in step S11), the changeover switch. 54 designates all the window glasses 111 to 116 or designates at least one of the window glasses 111 to 113, and instructs the CPU 10 to switch the light control glass 110 from the transparent state to the high density state. When input (YES route in step S12), the current position (latitude / longitude information) of the automobile 100 detected by the GPS position detector 21 by the position determination unit 11 may travel in a specific area (the automobile 100 travels). Judge whether it belongs to areas other than public roads (for example, private land or convenience store parking lots) and speed Determining by the step 12, whether the moving speed of the vehicle 100 detected by the speed sensor 22 (vehicle speed) is zero, i.e. whether the vehicle 100 is stopped (step S13).

  And when it determines with the present position of the motor vehicle 100 belonging to a specific area | region and the motor vehicle 100 has stopped (YES route of step S14), each light control glass 110 which comprises the window glasses 111-113 by the adjustment means 10b. Is adjusted to less than a predetermined value (70%) and each light control glass 110 is switched from a transparent state to a high concentration state (step S15), while the current position of the automobile 100 does not belong to a specific area, or When it is determined that the automobile 100 is not stopped (NO route of step S14), the driver (switching operator) is informed that the switching cannot be performed without performing the switching adjustment to the high concentration state by the adjusting means 10b. An error is notified (step S16). The error notification is performed by a beep sound or an error display on the console display.

When the window glasses 111 to 113 are already set to a high concentration state (a state where the transmittance of visible light is less than a predetermined value (70%)) (NO route of step S11), all of the changeover switches 54 are used to When the window glass 111-116 is designated or at least one of the window glasses 111-113 is designated, and an instruction to switch the light control glass 110 from the high density state to the transparent state is input to the CPU 10 ( In step S17, the YES route), the adjusting means 10b immediately adjusts the transmittance of the light control glasses 110 forming the window glasses 111 to 113 to a predetermined value (70%) or more, and the light control glasses 110 are in a high concentration state. Is switched to a transparent state (step S20).

  Further, the window glasses 111 to 113 are already set to a high concentration state (a state where the transmittance of visible light is less than a predetermined value (70%)) (NO route in step S11), and the dimming is performed from the changeover switch 54. In a state where the switching instruction from the high concentration state of the glass 110 to the transparent state is not input to the CPU 10 (NO route of step S17), detection by the GPS position detection unit 21 and the speed sensor 22 and detection thereof at every predetermined control cycle. The determination by the position determination means 11 and the speed determination means 12 based on the result is executed (step S18), and the position determination means 11 determines that the current position of the automobile 100 does not belong to the specific area, or the speed determination means 12 determines that the automobile 100 has started moving (NO route of step S19), By means 10b, the transmittance of each light control glass 110 forming the window glasses 111 to 113 is immediately adjusted to a predetermined value (70%) or more, and each light control glass 110 is switched from a high concentration state to a transparent state (step). S20).

  As shown in FIG. 8, when the window glasses 114 to 116 are set in a transparent state (a state in which the transmittance of visible light is a predetermined value (70%) or more) (YES route in step S21), the changeover switch. 54 designates all the window glasses 111 to 116, or designates at least one of the window glasses 114 to 116, and instructs the CPU 10 to switch the light control glass 110 from the transparent state to the high density state. When input (YES route of step S22), the adjusting means 10b immediately adjusts the transmittance of each light control glass 110 forming the window glass 114 to 116 to be less than a predetermined value (70%), and each light control glass. 110 is switched from the transparent state to the high density state (step S23).

  Then, when the window glasses 114 to 116 are already set to a high concentration state (a state where the transmittance of visible light is less than a predetermined value (70%)) (NO route of step S21), from the changeover switch 54, By designating all the window glasses 111 to 116 or at least one of the window glasses 114 to 116, an instruction to switch the light control glass 110 from the high density state to the transparent state is input to the CPU 10. (YES route of step S24), the transmittance of each light control glass 110 forming the window glass 114 to 116 is immediately adjusted to a predetermined value (70%) or more by the adjusting means 10b, and each light control glass 110 is high. The density state is switched to the transparent state (step S25).

  When at least one of the window glasses 111 to 116 is set in a transparent state and the brightness adjustment mode is set by the changeover switch 54, the window glass is set in a transparent state. With respect to the light control glass 110 of the window glass, the transmittance is adjusted by the adjusting means 10b according to the brightness outside the vehicle 100 (the degree of brightness outside the passenger compartment) detected by the brightness sensor 23. For example, when the brightness outside the automobile 100 is low (that is, when the outside of the vehicle is dark), the transmittance of each of the light control glasses 110 is adjusted to ensure a field of view, while when the brightness outside the automobile 100 is high (that is, the outside of the vehicle is bright). In the case), the transmittance of each light control glass 110 is adjusted to be low to reduce the glare experienced by the driver and the passenger. However, when adjusting the transmittance to be low, the transmittance is not adjusted so low that the window glass is in a high concentration state, and glare is ensured while ensuring visibility through the window glass (light control glass 110). Adjust the transmittance as low as possible.

[2-2] Display control operation of the vehicle control device of this embodiment:
Next, the display control operation (the operation of the display control function of the adjusting means 10b) of the vehicle control device of the present embodiment will be described with reference to FIGS. 9 is a flowchart for explaining the display control operation (display control operation for the rear window glass 116) of the vehicle control device 101 of this embodiment, and FIG. 10 is the display control operation of the vehicle control device 101 of this embodiment ( FIG. 11 is a flowchart for explaining the display control operation for the front window glass 111 and the front side window glasses 112 and 113, and FIG. 11 shows the display control operation for the vehicle control device 101 of this embodiment (display control operation for the rear side window glasses 114 and 115). It is a flowchart for demonstrating.

  As described above, the CPU 10 (the display control function of the adjusting means 10b) operates in accordance with an instruction from the display instruction input unit 55, and the rear window glass 116 is adjusted according to the flowchart shown in FIG. 9 (steps S31 to S42). Display control of the light glass 110 (organic EL element layer 140) is performed, and the window glasses 111 to 111 in front of and on both sides of the driver, which are objects of the road transport vehicle security standard (Article 29, paragraph 4). About 113, display control of the light control glass 110 (organic EL element layer 140) is performed according to the flowchart shown in FIG. 10 (steps S51 to S58), and the other window glasses 114 and 115 are shown in the flowchart shown in FIG. Light control glass 110 (organic EL element layer 14) according to steps S61 to S65) ) Performs a display control of.

  As shown in FIG. 9, the display instruction input unit 55 designates the rear window glass 116, and an execution instruction for color display by the organic EL element layer 140 in the light control glass 110 of the rear window glass 116 is input to the CPU 10. Then (YES route in step S31), it is determined whether or not the execution instruction is to set the brake display mode and the direction instruction display mode (step S32).

  When the execution instruction is to set the brake display mode and the direction instruction display mode (YES route of step S32), the display instruction input unit 55 thereafter inputs a setting release instruction for these modes. Steps S33 to S36 are executed by the display control function of the adjusting unit 10b (until YES is determined in step S37). In other words, when the driver operates the brake pedal 52 (YES route of step S33), the brake lamp is turned on and at the same time, the brake display as shown in FIG. An image (an image including “brake!”) Is displayed (step S34). When the driver operates the direction indicator operation unit 53 (from the NO route in step S33 to the YES route in step S35), the turn signal corresponding to the indicated direction is turned on, and at the same time, the display control function of the adjusting unit 10b allows the rear window to be turned on. On the glass 116, for example, a display image for direction indication as shown in FIG. 6A (an image including a large right arrow corresponding to the right direction indication) is displayed (step S36). Then, when an instruction to cancel the setting of these modes is input from the display instruction input unit 55 (YES route of step S37), the setting of the brake display mode and the direction instruction display mode is canceled (step S38).

On the other hand, when the execution instruction does not set the brake display mode and the direction instruction display mode (NO route of step S32), the execution instruction is the original image data stored in the ROM of the storage unit 30. The display control function of the adjusting means 10b determines whether the display instruction is an arbitrary image specified from among the above, or the light emission / display instruction for the specified color. Then, the data relating to the designated image or color is read from the ROM of the storage unit 30 by the display control function of the adjusting means 10b (step S39), and the arbitrary image or the designated color is rear-windowed based on the read data. Light is emitted and displayed on the glass 116 (step S40). The display in step S40 is continued until a display cancellation instruction is input from the display instruction input unit 55 (until YES is determined in step S41), and when a display cancellation instruction is input from the display instruction input unit 55 (step S41). (YES route of S41), the display of the arbitrary image or the designated color is canceled (step S42).

  In the example shown in FIG. 9, the case where both the brake display mode and the direction indication display mode are set is described, but only one of the brake display mode and the direction indication display mode is designated. In this case, a brake display or a direction indication display corresponding to the designated mode is performed.

  As shown in FIG. 10, an instruction to execute color display by the organic EL element layer 140 in the light control glass 110 by designating at least one of the window glasses 111 to 113 from the display instruction input unit 55 (storage unit 30). When an instruction to display an arbitrary image designated from the original image data stored in the ROM or a light emission / display instruction for the designated color is input to the CPU 10 (YES route in step S51), the position determination means 11, the current position (latitude / longitude information) of the automobile 100 detected by the GPS position detector 21 is a specific area (an area other than the public road on which the automobile 100 can travel; for example, a private land or a convenience store parking lot). And whether the speed is detected by the speed sensor 22 by the speed determination means 12 or not. Whether the moving speed of the vehicle 100 (vehicle speed) is zero, i.e. it determines whether vehicle 100 is stopped (step S52).

  And when it determines with the present position of the motor vehicle 100 belonging to a specific area | region and the motor vehicle 100 has stopped (YES route of step S53), the data regarding the designated image or color by the display control function of the adjustment means 10b Is read from the ROM of the storage unit 30 (step S54), and an arbitrary image or a designated color is emitted and displayed on the light control glass 110 based on the read data (step S55). The display in step S55 is performed until a display cancellation instruction is input from the display instruction input unit 55, until the current position of the automobile 100 is determined not to belong to the specific area by the position determination unit 11, or the speed It is continued until it is determined by the determination means 12 that the automobile 100 has started moving (until YES is determined in step S56), a display release instruction is input from the display instruction input unit 55, or the current position of the automobile 100 is outside the specific region. If the vehicle 100 starts to move (YES route of step S56), the display of the arbitrary image or the designated color is canceled (step S57).

  On the other hand, when it is determined in step S53 that the current position of the automobile 100 does not belong to the specific area or the automobile 100 is not stopped (NO route), display control is performed by the display control function of the adjusting means 10b. The driver (switching operator) is notified as an error that the display cannot be performed (step S58). The error notification is performed by a beep sound or an error display on the console display.

  As shown in FIG. 11, an instruction to execute color display by the organic EL element layer 140 in the light control glass 110 by designating at least one of the window glasses 114 and 115 from the display instruction input unit 55 (storage unit 30). When an instruction to display an arbitrary image designated from the original image data stored in the ROM or a light emission / display instruction for the designated color is input to the CPU 10 (YES route in step S61), the adjusting means 10b. With the display control function, data relating to the designated image or color is read from the ROM of the storage unit 30 (step S62), and an arbitrary image or designated color is emitted from the dimming glass 110 based on the read data. It is displayed (step S63). The display in step S63 is continued until a display cancellation instruction is input from the display instruction input unit 55 (YES in step S64), and when a display cancellation instruction is input from the display instruction input unit 55 (step (YES route in S64), the display of the arbitrary image or the designated color is canceled (step S65).

[2-3] Doze driving suppression control operation of the vehicle control device of the present embodiment:
[2-3-1] Dozing operation suppression control operation at start (1):
Next, the dozing operation suppression control operation (operation of the engine controller 10a and the adjusting means 10b) at the start of the vehicle control device 101 of the present embodiment configured as described above will be described with reference to the flowchart of FIG. .

  When the ignition is turned on (step S121 in FIG. 12), the CPU 10 (the engine controller 10a and the adjusting unit 10b) displays a procedure for performing a dozing test on the display unit 60 before starting the engine. If the window is in a high density state at this time, the CPU 10 returns it to the transparent state.

  When the driver's face image and driving posture are photographed by the dozing detection means 57 in accordance with the displayed procedure, the photographing result of the dozing detection means 57 is captured by the CPU 10. Then, the dozing determination unit 14 in the CPU 10 registers the driver's face image or driving posture as an initial image (step S122 in FIG. 12).

  This initial image is used by the dozing determination unit 14 as a determination criterion for the presence or absence of a dozing. When the initial image is a driver's face image, the initial value of the degree of eye opening (h1 / w1, h2 / w2) included in the driver's face image described above is employed as the threshold value. Further, if the initial image is a driving posture as viewed from the side of the driver, an initial value of the inclination of the back is adopted as the threshold value. In this case, an average value for a predetermined time of h1 / w1 and h2 / w2 is used.

  However, at this point in time, a state equivalent to a snooze may occur, which may cause the driver's face image to have a very small degree of eye opening, or the driving posture may be bent forward or swaying. Then, doze determination is performed (step S123 in FIG. 12). That is, the dozing determination unit 14 determines whether there is no dozing / occurs of dozing based on the detection result of the driver detected by the dozing detection unit 57, and transmits the determination result to the adjustment unit 10b. When it is determined that a doze occurs, the initial value is not used as a threshold value.

  Note that there are individual differences in the face image and driving posture, such as a small degree of eye opening and a tendency to bend forward. Therefore, in addition to acquiring and determining this image, it is also desirable to measure reflexes and the like in order to determine the driver's consciousness level and physical condition.

  For example, under the control of the CPU 10, the time until the driver actually blinks three times and the interval between each blink after the message “Please continue blinking three times” is displayed on the display unit 60. If the display unit 60 displays a message “please step on the brake pedal” and measures the time until the driver actually steps on the brake pedal 52, or if the display unit 60 has a touch panel In this case, it is possible to determine the driver's consciousness level and physical condition by displaying a traffic rule test on the display unit 60 and making a determination based on the result (correctness of answer, answer time).

  In particular, the time until the brake pedal 52 is depressed is desirable because it is possible to detect a state that is not suitable for driving, including abnormalities in the brain and body other than sleeping. It is also desirable to be able to detect conditions unsuitable for driving, such as brain disorders other than snoozing, by testing traffic rules.

Instead of the brake pedal 52, an operation of a hand brake lever or an operation of pressing various buttons can be employed.
When the dozing determination unit 14 determines that there is no dozing (NO in step S124 in FIG. 12), the adjusting unit 10b transmits an engine start instruction to the engine controller 10a, and the engine controller 10a starts the engine 40 (FIG. 12 in step S128). That is, the engine controller 10a that has received an instruction to start the engine drives a cell motor, a fuel injection device, etc. (not shown) to start the engine 40.

  On the other hand, when the dozing determination unit 14 determines that a dozing has occurred (YES in step S124 in FIG. 12), the dimming glass 110, preferably the window glass 111, which forms at least the window glasses 111 to 113 by the adjusting unit 10b. The transmittance of each light control glass 110 constituting ~ 116 is adjusted to a high density (less than a predetermined value (70%)) by the adjusting means 10b (step S125 in FIG. 12). In this case, since it is determined that a drowsiness has occurred, it is desirable that each light control glass is controlled to a concentration as high as possible (low transmittance) so that it is substantially impossible to drive.

  In this case, not only when the light control glass 110 is controlled to a high density from the transparent state, but also when the high density state is already maintained by the light control operation described in FIG. 7 or FIG. Furthermore, a mode in which the density is controlled to be higher from the already high density by the dimming control operation described with reference to FIGS. 7 and 8 can be considered.

  If the dozing determination unit 14 determines that a drowsiness has occurred (YES in step S124 in FIG. 12), the front window glass is controlled by the display control function of the adjusting unit 10b along with the above-described control of increasing the concentration of the light control glass. 111 and the rear window glass 116, as a color display by the organic EL element layer 140 in the light control glass 110, for example, a hazard lamp display image (both right direction instruction and left direction instruction) as shown in FIG. A corresponding image including a large right arrow is displayed (step S126 in FIG. 12). In this case, it can be informed to the outside that it is determined that doze has occurred and the vehicle cannot travel. Instead of the hazard lamp display, a parking lamp display that is always lit red may be used.

  Further, when it is determined by the dozing determination unit 14 that a dozing has occurred (YES in step S124 in FIG. 12), the display control function of the adjusting unit 10b is used together with the control for increasing the density of the light control glass and the hazard lamp display. In any one of the window glasses or the entire window glass, data relating to the designated image or color is read from the ROM of the storage unit 30, and an arbitrary image or designated color is controlled based on the read data. Is emitted and displayed (step S127 in FIG. 12). In this case, it is desirable to use an image or a color that informs the outside that it is determined that a drowsiness has occurred and the vehicle cannot travel.

  As described above, when the dozing determination unit 14 determines that a drowsiness has occurred (YES in step S124 in FIG. 12), the adjustment unit 10b increases the concentration of the window glass (step S125 in FIG. 12). After executing the hazard lamp display of the window (step S126 in FIG. 12) and the predetermined image / color display of the window (step S127 in FIG. 12), the adjusting means 10b transmits an engine start instruction to the engine controller 10a, and the engine The controller 10a starts the engine 40 (step S128 in FIG. 12). That is, the engine controller 10a that has received an instruction to start the engine drives a cell motor, a fuel injection device, etc. (not shown) to start the engine 40.

In the above embodiment, when the dozing determination unit 14 determines that a dozing has occurred (YES in step S124 in FIG. 12), the adjustment unit 10b increases the concentration of the window glass (step S125 in FIG. 12). The engine 40 is started after the hazard lamp display of the window (step S126 in FIG. 12) and the predetermined image / color display of the window (step S127 in FIG. 12) are executed. If the concentration of the window glass can be increased before starting and running, the order of execution may be varied.

  In addition, even if the concentration of the window is increased when it is determined that the snoozing occurs, a situation where the driver in the snoozing state makes the vehicle forcibly run is also assumed. Therefore, in order to prevent such traveling, the engine controller 10a in the CPU 10 limits the upper limit of the engine speed to the engine speed in an idling state or an idle-up state when using an air conditioner. It is also effective to take measures against inability to run such that the shift is not executed electrically regardless of the operation, and the transmission is controlled to the neutral state when there is a shift operation in the case of an automatic vehicle. And even if such a measure against inability to travel is taken, there will be no problem with the use of air conditioning while parked.

  Moreover, in the above embodiment, when the dozing determination unit 14 determines that a dozing occurs (YES in step S124 in FIG. 12), the adjustment unit 10b increases the concentration of the window glass (step S125 in FIG. 12). The hazard lamp display of the window (step S126 in FIG. 12) and the predetermined image / color display of the window (step S127 in FIG. 12) were executed, but in order to suppress running in the dozing state, Only high density may be executed, high density of window glass and window hazard lamp display may be used, or high density of window glass and predetermined image / color display of window may be used.

  According to the vehicle control apparatus 101 of this embodiment, if it is determined that the driver is falling asleep, the transmittance of the light control glass 110 is adjusted to a high concentration less than a predetermined value, and the vehicle cannot travel. On the other hand, since the start of the engine 40 is not limited, it is possible to use air conditioning. That is, although the engine 40 can be used for cooling and heating, it is not suitable for driving, so it is possible to effectively suppress the drowsy driving without causing discomfort to the occupants in the vehicle, and privacy and security are also improved. Secured.

  Further, in this embodiment, since the engine speed of the engine 40 is not limited to idling only, the idle-up function at the time of using the air conditioner operates effectively. There is an advantage that no discomfort is given to the passenger.

  When the driver wants to resume driving after the light control glass 110 has been determined to have fallen asleep and the concentration of the light control glass 110 has been increased, the CPU 10 performs the above-described measurement of reflexes and traffic by performing a predetermined operation. A rule test or the like is executed, and if it is determined that there is no problem in driving, the light control glass 110 is returned to a transparent state. Alternatively, the driver may stop the engine and turn on the ignition again, so that the start-time doze driving suppression control may be executed from the beginning.

[2-3-2] Dozing operation suppression control operation at start (2):
Next, a drowsiness driving suppression control operation (operation of the engine controller 10a and the adjusting means 10b) at the start of the vehicle control device 101 of the present embodiment configured as described above will be described with reference to the flowchart of FIG. .

  Here, the description will be made on the assumption that the window of the automobile is in a standard state (specified value (70%) or more). The operation when the window is in the high density state (less than the specified value) in the initial state will be described later.

  When the ignition key is turned on by the driver, the CPU 10 (engine controller 10a and adjusting means 10b) starts executing the control sequence according to the flowchart of FIG. 17, for example, before the engine is started, the display unit 60 Displays the procedure for performing a doze test.

  When the driver's face image and driving posture are photographed by the dozing detection means 57 in accordance with the displayed procedure, the photographing result of the dozing detection means 57 is captured by the CPU 10. Then, the dozing determination unit 14 in the CPU 10 registers the driver's face image or driving posture as an initial image (step S1701 in FIG. 17).

  This initial image is used by the dozing determination unit 14 as a determination criterion for the presence or absence of a dozing. When the initial image is a driver's face image, the initial value of the degree of eye opening (h1 / w1, h2 / w2) included in the driver's face image described above is employed as the threshold value. Further, if the initial image is a driving posture as viewed from the side of the driver, an initial value of the inclination of the back is adopted as the threshold value. In this case, an average value for a predetermined time of h1 / w1 and h2 / w2 is used.

  However, at this point in time, a state equivalent to a snooze may occur, which may cause the driver's face image to have a very small degree of eye opening, or the driving posture may be bent forward or swaying. Then, doze determination is performed (step S1702 in FIG. 17).

  That is, the dozing determination unit 14 determines whether or not there is a possibility of falling asleep based on the detection result of the driver detected by the dozing detection unit 57, and transmits the determination result to the adjustment unit 10b. When it is determined that a doze occurs, the initial value is not used as a threshold value.

  Note that there are individual differences in the face image and driving posture, such as a small degree of eye opening and a tendency to bend forward. Therefore, in addition to acquiring and determining this image, it is also desirable to measure reflexes and the like in order to determine the driver's consciousness level and physical condition.

  For example, under the control of the CPU 10, the time until the driver actually blinks three times and the interval between each blink after the message “Please continue blinking three times” is displayed on the display unit 60. In addition, the reaction time is measured by measuring the time from when the message “please step on the brake pedal” is displayed on the display unit 60 until the driver actually steps on the brake pedal 52. Further, the time of the expected depression interval when the brake pedal 52 is repeatedly depressed can also be used for detection.

  In particular, the reaction time until the brake pedal 52 is depressed is desirable because it can detect a state that is not suitable for driving, including abnormalities in the brain and body other than sleeping. It is also desirable to be able to detect conditions unsuitable for driving, such as brain disorders other than snoozing, by testing traffic rules. As described above, it is determined whether or not there is a possibility of falling asleep (steps S1701 and S1702 in FIG. 17).

  In addition, when the display unit 60 includes a touch panel, a traffic rule test is displayed on the display unit 60, and the determination is made based on the result (answer correct / answer time), thereby determining the driver's consciousness level and physical condition. It becomes possible.

  In this case, if the time required to start blinking or depressing the brake pedal is equal to or longer than the predetermined time, it can be determined that there is a possibility of falling asleep. The predetermined time may be registered for each driver, or a common time (for example, 1 second) may be set for all the drivers. In addition, the determination criteria may be changed depending on whether the driving is a general road, a highway, or a long-distance driving. That is, it is possible to tighten the criteria for highway and long distance driving.

Further, the identification means 19 in the CPU 10 identifies each driver based on biometric data such as a fingerprint, a palm print, and a face photograph acquired by the biometric sensor 59. If the data matches the driver's data registered in advance, the driver is registered as a newly registered driver # 1 if there is no matching data (steps S1701 and S1702 in FIG. 17).

That is, the presence or absence of a nap is determined for each driver as necessary, and a history is stored or compared with a past dozing history as described later.
In addition, if there is a face image registered in the past, it is possible to make a doze determination from the current face image as compared with the registered face image.

  Then, the dozing determination unit 14 determines whether there is a possibility of falling asleep or a possibility of falling asleep based on the face image and posture of the driver detected by the dozing inspection unit 57 and the reaction time, and the determination result is adjusted by the adjusting unit 10b. To communicate.

  If the dozing determination unit 14 determines that there is no dozing (NO in step S1703 in FIG. 17), the adjusting unit 10b transmits an engine start instruction to the engine controller 10a, and the engine controller 10a starts the engine 40 (FIG. 17 in step S1708). That is, the engine controller 10a that has received an instruction to start the engine drives a cell motor, a fuel injection device, etc. (not shown) to start the engine 40.

  If there is an instruction to stop the engine (YES in step S1709 in FIG. 17), the engine controller 10a stops the engine 40 (step S1710 in FIG. 17), and the adjustment unit 10b stores a history of no doze determination. (Step S1711 in FIG. 17).

On the other hand, if the dozing determination unit 14 determines that there is a possibility of falling asleep (YES in step S1703 in FIG. 17), the current position of the automobile 100 (latitude / longitude information) based on the detection result of the GPS position detection unit 21. ) Belongs to a specific area (an area other than a public road or a private road on which the automobile 100 can travel; for example, a private land or a convenience store parking lot) (step S1704 in FIG. 17).

  If not only the position but also the speed is set as a determination criterion, whether or not the moving speed (vehicle speed) of the automobile 100 detected by the speed sensor 22 by the speed judging means 12 is zero, that is, the automobile 100 is determined. It is determined whether or not the vehicle is stopped.

  Here, when it is determined by the dozing determination unit 14 that there is a possibility of falling asleep (YES in step S1703 in FIG. 17), the current position (latitude / longitude information) of the automobile 100 is the specific region (the travel of the automobile 100). If the vehicle does not belong to a region other than a public road or private road that can be moved; for example, private land or a parking lot at a convenience store (NO in step S1704 in FIG. 17), or if the speed is other than zero, the engine controller 10a Without starting the engine 40, the adjusting means 10b stores the history of having a doze determination outside the specific area in the storage unit and ends the process (step S1711 in FIG. 17).

  That is, according to this control, when it is determined that there is a possibility of falling asleep when the engine of the vehicle is started, the transmittance of the light control glass is not adjusted below a specified value if it is outside the specific region, that is, on the road. Since the engine is controlled so as not to start, it is possible to effectively suppress the drowsiness operation while maintaining a legal state without violating laws and regulations such as safety standards for vehicle transportation.

Here, when it is determined by the dozing determination unit 14 that there is a possibility of falling asleep (YES in step S1703 in FIG. 17), the current position (latitude / longitude information) of the automobile 100 is the specific region (the travel of the automobile 100). If it belongs to an area other than on public roads or private roads that can move; for example, private land or a convenience store parking lot (YES in step S1704 in FIG. 17), or the position is a specific area and the speed is zero. If it exists, the transmittance | permeability of each light control glass 110 which comprises at least the window glass 111-113 by the adjustment means 10b, Preferably each light control glass 110 which comprises the window glasses 111-116 is high density (regulated value) by the adjustment means 10b. (Less than (70%)) (step S1705 in FIG. 17). In this case, since it is determined that there is a possibility of falling asleep, it is desirable that each light control glass is controlled to a concentration as high as possible (low transmittance) so that it is substantially impossible to drive.

  In this case, not only when the light control glass 110 is controlled to a high density from the transparent state, but also when the high density state is already maintained by the light control operation described in FIG. 7 or FIG. Furthermore, a mode in which the density is controlled to be higher from the already high density by the dimming control operation described with reference to FIGS. 7 and 8 can be considered.

  Further, when it is determined by the dozing determination unit 14 that there is a possibility of falling asleep (YES in step S1703 in FIG. 17), the current position (latitude / longitude information) of the automobile 100 is a specific region (traveling movement of the automobile 100). If it belongs to an area other than on public roads or private roads (eg, private land or a parking lot at a convenience store) (YES in step S204 in FIG. 14), the adjusting means together with the control of the high concentration of the light control glass With the display control function of 10b, as the color display by the organic EL element layer 140 in the light control glass 110 on the front window glass 111 and the rear window glass 116, for example, a hazard lamp display image (right An image including a large right arrow corresponding to both the direction instruction and the left direction instruction is displayed (step in FIG. 17). 1706). In this case, it is determined that there is a possibility of falling asleep and it is possible to inform the outside that the vehicle cannot travel. Instead of the hazard lamp display, a parking lamp display that is always lit red may be used.

  Furthermore, when it is determined by the dozing determination unit 14 that there is a possibility of falling asleep (YES in step S1703 in FIG. 17), the current position (latitude / longitude information) of the automobile 100 is a specific region (traveling movement of the automobile 100). If it belongs to an area other than on public roads or private roads (eg, private land or a convenience store parking lot) (YES in step S204 in FIG. 14), control of high concentration of the light control glass and hazard lamp display At the same time, by the display control function of the adjusting means 10b, the data related to the designated image or color is read from the ROM of the storage unit 30 in any one of the window glasses or the entire window glass, and based on the read data. An arbitrary image or a designated color is emitted and displayed on the light control glass 110 (step S1707 in FIG. 17).In this case, it is desirable to use an image or color that informs the outside that it is determined that there is a possibility of falling asleep and the vehicle cannot travel.

  As described above, when the dozing determination unit 14 determines that there is a possibility of falling asleep (YES in step S1704 in FIG. 17), the adjustment unit 10b increases the concentration of the window glass (step S1705 in FIG. 17). ) After executing the hazard lamp display of the window (step S1706 in FIG. 17) and the predetermined image / color display of the window (step S1707 in FIG. 17), the adjusting means 10b transmits an engine start instruction to the engine controller 10a. The engine controller 10a starts the engine 40 (step S1708 in FIG. 17). That is, the engine controller 10a that has received an instruction to start the engine drives a cell motor, a fuel injection device, etc. (not shown) to start the engine 40.

  If there is an instruction to stop the engine (YES in step S1709 in FIG. 17), the engine controller 10a stops the engine 40 (step S1710 in FIG. 17), and the adjusting unit 10b has a history of a doze determination in a specific area. Is stored in the storage unit (step S1711 in FIG. 17).

  In the above embodiment, in the specific area, when the dozing determination unit 14 determines that there is a possibility of falling asleep (YES in step S1703 in FIG. 17 and YES in S1704), the adjustment unit 10b increases the height of the window glass. After executing the concentration (step S1705 in FIG. 17), the hazard lamp display of the window (step S1706 in FIG. 17), and the predetermined image / color display of the window (step S1707 in FIG. 17), the engine 40 is started ( Although step S1708 in FIG. 17 is performed, the order of execution may be changed almost simultaneously, that is, if the concentration of the window glass can be increased before the engine is started and the vehicle starts running. Further, immediately after the engine is started, the window density may be increased and various displays may be executed. In this case, the burden on the battery can be reduced.

  In addition, even if it is determined that there is a possibility of falling asleep and the concentration of the window is increased, a drunk driver may forcibly drive the vehicle. Therefore, in order to prevent such traveling, the engine controller 10a in the CPU 10 limits the upper limit of the engine speed to the engine speed in an idling state or an idle-up state when using an air conditioner. It is also effective to take measures against inability to run such that the shift is not executed electrically regardless of the operation, and the transmission is controlled to the neutral state when there is a shift operation in the case of an automatic vehicle. And even if such a measure against inability to travel is taken, there will be no problem with the use of air conditioning while parked.

  Moreover, in the above embodiment, when the dozing determination unit 14 determines that there is a possibility of falling asleep in a specific area (YES in step S1703 in FIG. 17, YES in S1704), the adjustment unit 10b has a high density of the window glass. 17 (step S1705 in FIG. 17), hazard lamp display of the window (step S1706 in FIG. 17), and predetermined image / color display of the window (step S1707 in FIG. 17). In order to suppress driving, only the concentration of the window glass may be increased, or the concentration of the window glass and the hazard lamp display of the window may be displayed. Color display may be used.

  According to the vehicle control device 101 of this embodiment, if it is determined that there is a possibility of falling asleep, the transmittance of the light control glass 110 is adjusted to a high concentration less than a specified value, and the vehicle cannot run. On the other hand, since the start of the engine 40 is not limited, it is possible to use air conditioning. That is, although the engine 40 can be used for cooling and heating, it is not suitable for traveling, so that it is possible to effectively suppress the drowsy driving without giving uncomfortable feeling to the passengers in the vehicle.

  Further, in this embodiment, since the engine speed of the engine 40 is not limited to idling only, the idle-up function at the time of using the air conditioner operates effectively. There is an advantage that no discomfort is given to the passenger.

  In this embodiment, the adjusting means 10b accumulates the history of the result of the determination of dozing at the start of the engine, and if the determination that there is a possibility of falling asleep is more than a predetermined number of times, the adjustment means 10b can fall asleep at the start of the engine Even if it is determined that the vehicle is located and the vehicle location is determined to belong to a specific area, the transmittance of the light control glass is adjusted to be less than the specified value, but the engine is not started. You may control.

  In this case, in order to adjust the transmittance of the window below the specified value in a specific area, it does not violate laws and regulations such as vehicle transport safety standards, while maintaining a legal state and a high concentration of the window. By making the engine and the engine not started, it is possible to effectively suppress the drowsy driving.

  Further, in this embodiment, the adjusting unit 10b identifies the driver based on the detection result of the biosensor 59, and the history of the determination result of the dozing determination unit at the start of the engine is identified for the identified driver. If it is stored and the possibility of falling asleep is more than a predetermined number of times, it is determined that there is a possibility of falling asleep when the engine is started, and the vehicle location is determined to belong to a specific area. However, although the transmittance of the light control glass is adjusted to be less than a specified value, it is possible to control so that the engine is not started. In this case, in order to adjust the transmittance of the window below the specified value in a specific area, it does not violate laws and regulations such as vehicle transport safety standards, while maintaining a legal state and a high concentration of the window. By making the engine and the engine not started, it is possible to effectively suppress the drowsy driving.

  In addition, when a plurality of drivers use the same vehicle alternately, it is desirable to perform the control of the present embodiment after identifying the drivers with the biometric data. On the other hand, in the case of a vehicle used by only one person, it is not necessary to perform driver identification by the biosensor 59.

  When the driver wants to resume driving after the light control glass 110 has been determined to have fallen asleep and the concentration of the light control glass 110 has been increased, the CPU 10 performs the above-described measurement of reflexes and traffic by performing a predetermined operation. A rule test or the like is executed, and if it is determined that there is no problem in driving, the light control glass 110 is returned to a transparent state. Alternatively, the driver may stop the engine and turn on the ignition again, so that the start-time doze driving suppression control may be executed from the beginning.

[2-3-3] Dozing operation suppression control operation during running:
Next, a drowsy driving suppression control operation (operation of the engine controller 10a and the adjusting means 10b) during traveling of the vehicle control device 101 of the present embodiment configured as described above will be described with reference to the flowchart of FIG. . Note that the state where the engine is actually started but has not started traveling is also in a state where traveling can be started, and therefore, here, it will be treated as dozing operation suppression control during traveling.

  The CPU 10 (the engine controller 10a and the adjusting means 10b) periodically executes the program for the control of the dozing operation during driving illustrated in FIG. 13 after starting the engine or during the traveling of the vehicle.

In the vehicle control apparatus 101 of this embodiment, the dozing detection unit 57 detects the dozing from the driving state of the driver (opening degree of eye or change in posture) (step S131 in FIG. 13).
It should be noted that the dozing detection means 57 is preferably a highly sensitive and wide dynamic range camera so that the driver's dozing can be detected effectively even during daytime or at night.

  When the dozing detection means 57 detects every certain time, the detection result of the dozing detection means 57 is taken into the CPU 10. Then, the dozing determination unit 14 in the CPU 10 determines whether or not the driver is falling asleep while driving from the detection result of the dozing detection unit 57 (step S132 in FIG. 13).

  The dozing determination unit 14 determines whether there is no dozing / occurrence of dozing based on the degree of opening of the eyes and the change in posture detected by the dozing detection unit 57, and transmits the determination result to the adjustment unit 10b.

  During driving, the face image and driving posture image may be disturbed due to slight posture changes and left and right confirmations, so both the face image and driving posture may be used, or the average value for a predetermined time It is desirable to determine from the viewpoint of preventing malfunction.

  For example, a state where the degree of opening of the eye is 50% or less at the time of initial registration continues for one second or more. Moreover, if the number of times of forward bending is one or more times per minute and the state continues several times, such as normal and driving posture, it is considered to be asleep. This numerical value is an example, and various modifications and settings are possible.

  When the dozing determination unit 14 determines that there is no dozing (NO in step S133 in FIG. 13), the adjustment unit 10b does not issue a special instruction and maintains the normal running state (in step S133 in FIG. 13). NO → end).

  On the other hand, if it is determined by the dozing determination unit 14 that a drowsiness has occurred (YES in step S133 in FIG. 13), the adjusting unit 10b can park or stop nearest by the detection result of the GPS position detection unit 21 and the navigation program. A search to a place is executed (step S134 in FIG. 13). Then, the display unit 60 is guided to the parking and stopping location (steps S135 and S136 in FIG. 13). Alternatively, the CPU 10 instructs a car navigation device (not shown) to search for the nearest parking / stoppable location, and guides the vehicle to the parking / parking location (steps S135 and S136 in FIG. 13).

  In addition, it is desirable to perform an alarm sound or display during this guidance in order to prevent further sleep. In addition to this, it is also desirable to apply cool air from the air conditioner to the driver's face and head.

  Then, the position determination unit 11 determines whether the current position (latitude / longitude information) of the automobile 100 detected by the GPS position detection unit 21 belongs to the guidance destination, and the speed determination unit 12 It is determined whether or not the moving speed (vehicle speed) of the automobile 100 detected by the speed sensor 22 is zero, that is, whether or not the automobile 100 is stopped at the guidance destination (step S136 in FIG. 13).

  If the automobile 100 has reached the guidance destination (YES in step S136 in FIG. 13), at least the light control glasses 110 forming the window glasses 111 to 113, preferably the light control glasses 110 forming the window glasses 111 to 116. Is adjusted to a high density (less than a predetermined value (70%)) by the adjusting means 10b (step S137 in FIG. 13). In this case, since it is determined that a drowsiness has occurred, it is desirable that each light control glass is controlled to a concentration as high as possible (low transmittance) so that it is substantially impossible to drive.

  In this case, not only when the light control glass 110 is controlled from a transparent state to a high concentration, but also when the state where the light control glass 110 is already in a high concentration state is maintained by the light control operation described with reference to FIGS. 7 and 8. Including. Furthermore, in the case where the concentration is controlled to be higher in order to suppress the drowsy driving from the state where the concentration is already high by the light control operation described with reference to FIGS.

  Further, when the dozing determination unit 14 determines that a dozing has occurred (YES in step S133 in FIG. 13), and after reaching the guidance destination (YES in step S136 in FIG. 13), the above light control glass As a color display by the organic EL element layer 140 in the light control glass 110 on the front window glass 111 and the rear window glass 116 by the display control function of the adjusting means 10b, together with the control of the higher concentration of the light, for example, FIG. A hazard lamp display image (an image including a large right arrow corresponding to both the right direction instruction and the left direction instruction) is displayed (step S138 in FIG. 13). In this case, it can be informed to the outside that it is determined that doze has occurred and the vehicle cannot travel. Instead of the hazard lamp display, a parking lamp display that is always lit red may be used.

  Further, if the dozing determination unit 14 determines that a dozing has occurred (YES in step S133 in FIG. 13), and after reaching the guidance destination (YES in step S136 in FIG. 13), the light control glass The data relating to the designated image or color is read from the ROM of the storage unit 30 in any one of the window glasses or the entire window glass by the display control function of the adjusting means 10b along with the control of the density increase and the hazard lamp display. Then, an arbitrary image or a designated color is emitted and displayed on the light control glass 110 based on the read data (step S139 in FIG. 13). In this case, it is desirable to use an image or a color that informs the outside that it is determined that a drowsiness has occurred and the vehicle cannot travel.

  As described above, when the dozing determination unit 14 determines that a dozing occurs (YES in step S133 in FIG. 13), the adjustment unit 10b increases the concentration of the window glass (step S137 in FIG. 13). Although the window hazard lamp display (step S138 in FIG. 13) and the predetermined image / color display of the window (step S139 in FIG. 13) are executed, the adjusting means 10b does not stop the engine.

  Even if it is determined that a snooze has occurred and the concentration of the window is increased, a situation where the driver in a snoozing state drives the vehicle forcibly is also assumed. Therefore, in order to prevent such traveling, the engine controller 10a in the CPU 10 limits the upper limit of the engine speed to the engine speed in an idling state or an idle-up state when using an air conditioner. It is also effective to take measures against inability to run such that the shift is not executed electrically regardless of the operation, and the transmission is controlled to the neutral state when there is a shift operation in the case of an automatic vehicle. And even if such a measure against inability to travel is taken, there will be no problem with the use of air conditioning while parked.

  Moreover, in the above embodiment, when the dozing determination unit 14 determines that a dozing occurs (YES in step S134 in FIG. 13), the adjustment unit 10b increases the concentration of the window glass (step S137 in FIG. 13). The window hazard lamp display (step S138 in FIG. 13) and the predetermined image / color display of the window (step S139 in FIG. 13) were executed. It may be possible to execute only a high density of the window glass, a high density of the window glass and a hazard lamp display of the window, or a high density of the window glass and a predetermined image / color display of the window.

  According to the vehicle control device 101 of this embodiment, if it is determined that a drowsiness is detected and a drowsiness occurs, the transmittance of the light control glass 110 is adjusted to a high concentration less than a predetermined value after being guided to a parking and stopping location. Will be unable to run. On the other hand, since the start of the engine 40 is not limited, it is possible to use air conditioning. That is, although the engine 40 can be used for cooling and heating, it is not suitable for driving, so it is possible to effectively suppress the drowsy driving without causing discomfort to the occupants in the vehicle, and privacy and security are also improved. Secured.

  Further, in this embodiment, since the engine speed of the engine 40 is not limited to idling only, the idle-up function at the time of using the air conditioner operates effectively. There is an advantage that no discomfort is given to the passenger.

  In addition, not only the case of driving on the road (public road, private road) but also the case where the vehicle is temporarily stopped due to traffic jam or waiting for traffic lights on the road, This includes conditions where the vehicle can be run immediately, such as when the engine is started in a parking lot.

  Here, when the engine is started and before the start of driving, i.e., when the engine is started in a parking lot or other place where parking is possible, and when the vehicle is sleeping with the vehicle, the above guidance is omitted. Then, on the spot, the adjusting means 10b increases the concentration of the window glass (step S137 in FIG. 13), the hazard lamp display of the window (step S138 in FIG. 13), and the predetermined image / color display of the window (in FIG. 13). Step S139) may be executed.

  When the driver wants to resume driving after the light control glass 110 has been determined to have fallen asleep and the concentration of the light control glass 110 has been increased, the CPU 10 performs the above-described measurement of reflexes and traffic by performing a predetermined operation. A rule test or the like is executed, and if it is determined that there is no problem in driving, the light control glass 110 is returned to a transparent state. Alternatively, the driver may stop the engine and turn on the ignition again, so that the start-time doze driving suppression control may be executed from the beginning.

  Also in this embodiment, the driver is identified by the biometric sensor 59, the history of the doze determination result is stored, and when the same driver repeats the doze operation, the adjustment means is made to make the response stricter. 10b may change the control.

[2-4] Light control / display / drowsy driving suppression control operation of the vehicle control device of the present embodiment:
In the above embodiment, the dimming control, the display control, and the dozing operation suppression control have been described as being independent states.

  Here, referring to the flowchart of FIG. 14, a case where the dimming control, the display control, and the drowsy driving suppression control (starting drowsy driving suppression control and running nap driving suppression control) are collectively executed as a series of controls. explain.

[2-4-1] Dozing operation suppression control operation at start (1):
When the ignition is turned on (step S201 in FIG. 14), the CPU 10 (the engine controller 10a and the adjusting means 10b) performs a doze test on the display unit 60 before starting the engine as a start-up doze operation suppression control routine. Display the procedure. If the window is in a high density state at this time, the CPU 10 returns it to the transparent state.

  When the driver's face image and driving posture are photographed by the dozing detection means 57 in accordance with the displayed procedure, the photographing result of the dozing detection means 57 is captured by the CPU 10. Then, the dozing determination unit 14 in the CPU 10 registers the driver's face image or driving posture as an initial image (step S202 in FIG. 14).

  This initial image is used by the dozing determination unit 14 as a determination criterion for the presence or absence of a dozing. When the initial image is a driver's face image, the initial value of the degree of eye opening (h1 / w1, h2 / w2) included in the driver's face image described above is employed as the threshold value. Further, if the initial image is a driving posture as viewed from the side of the driver, an initial value of the inclination of the back is adopted as the threshold value.

  However, at this point in time, the driver's face image may have a very small degree of eye opening, or the driving posture may be bent forward or swaying. This is performed (step S203 in FIG. 14). That is, the dozing determination unit 14 determines whether there is no dozing / occurs of dozing based on the detection result of the driver detected by the dozing detection unit 57, and transmits the determination result to the adjustment unit 10b.

Note that there are individual differences in the face image and driving posture, such as a small degree of eye opening and a tendency to bend forward. Therefore, in addition to acquiring and determining this image, it is also desirable to measure reflexes and the like in order to determine the driver's consciousness level and physical condition.

  For example, under the control of the CPU 10, the time until the driver actually blinks three times and the interval between each blink after the message “Please continue blinking three times” is displayed on the display unit 60. If the display unit 60 displays a message “please step on the brake pedal” and measures the time until the driver actually steps on the brake pedal 52, or if the display unit 60 has a touch panel In this case, it is possible to determine the driver's consciousness level and physical condition by displaying a traffic rule test on the display unit 60 and making a determination based on the result (correctness of answer, answer time).

  In particular, the time until the brake pedal 52 is depressed is desirable because it is possible to detect a state that is not suitable for driving, including abnormalities in the brain and body other than sleeping. It is also desirable to be able to detect conditions unsuitable for driving, such as brain disorders other than snoozing, by testing traffic rules.

Further, the time of the expected depression interval when the brake pedal 52 is repeatedly depressed can also be used for detection.
When the dozing determination unit 14 determines that there is no dozing (NO in step S204 in FIG. 14), the adjusting unit 10b transmits an engine start instruction to the engine controller 10a, and the engine controller 10a starts the engine 40 (FIG. 14 in step S210). That is, the engine controller 10a that has received an instruction to start the engine drives a cell motor, a fuel injection device, etc. (not shown) to start the engine 40.

  On the other hand, when it is determined by the dozing determination unit 14 that a dozing has occurred (YES in step S204 in FIG. 14), the adjusting unit 10b controls each of the light control glasses 110, preferably the window glasses 111, which form at least the window glasses 111 to 113. The transmittance of each light control glass 110 constituting ~ 116 is adjusted to a high density (less than a predetermined value (70%)) by the adjusting means 10b (step S205 in FIG. 14). In this case, since it is determined that a drowsiness has occurred, it is desirable that each light control glass is controlled to a concentration as high as possible (low transmittance) so that it is substantially impossible to drive.

  In this case, not only when the light control glass 110 is controlled from a transparent state to a high concentration, but also when the state where the light control glass 110 is already in a high concentration state is maintained by the light control operation described with reference to FIGS. 7 and 8. Including. Furthermore, in the case where the concentration is controlled to be higher in order to suppress the drowsy driving from the state where the concentration is already high by the light control operation described with reference to FIGS.

  In addition, when the dozing determination unit 14 determines that a dozing occurs (YES in step S204 in FIG. 14), the adjustment unit 10b performs the control for increasing the concentration of the light control glass (step S205 in FIG. 14). As a color display by the organic EL element layer 140 in the light control glass 110 on the front window glass 111 and the rear window glass 116 by the display control function, for example, a hazard lamp display image (right direction instruction as shown in FIG. 6B). And an image including a large right arrow) corresponding to both the left direction instruction and the left direction instruction (step S206 in FIG. 14). In this case, it can be informed to the outside that it is determined that doze has occurred and the vehicle cannot travel. Instead of the hazard lamp display, a parking lamp display that is always lit red may be used.

Furthermore, when it is determined by the dozing determination unit 14 that a dozing has occurred (YES in step S204 in FIG. 14), the above-described control for increasing the concentration of the light control glass (step S205 in FIG. 14) and a hazard lamp display (FIG. 14 in step S206), the display control function of the adjusting means 10b, in any one of the window glasses or the entire window glass,
Data relating to the designated image or color is read from the ROM of the storage unit 30, and an arbitrary image or designated color is emitted and displayed on the light control glass 110 based on the read data (step S207 in FIG. 14). ). In this case, it is desirable to use an image or a color that informs the outside that it is determined that a drowsiness has occurred and the vehicle cannot travel.

  As described above, when the dozing determination unit 14 determines that a dozing occurs (YES in step S204 in FIG. 14), the adjustment unit 10b increases the concentration of the window glass (step S205 in FIG. 14). After executing the hazard lamp display of the window (step S206 in FIG. 14) and the predetermined image / color display of the window (step S207 in FIG. 14), the adjusting means 10b transmits an engine start instruction to the engine controller 10a, and the engine The controller 10a starts the engine 40 (step S208 in FIG. 14).

  That is, the engine controller 10a that has received an instruction to start the engine drives a cell motor, a fuel injection device, etc. (not shown) to start the engine 40. Then, until the engine is stopped by the operation of the ignition switch (YES in step S209 in FIG. 14), the CPU 10 continues the above-described window high concentration control and the like, and executes the dozing operation suppression control.

  In the above embodiment, when the dozing determination unit 14 determines that a dozing occurs (YES in step S204 in FIG. 14), the adjustment unit 10b increases the concentration of the window glass (step S205 in FIG. 14). The engine 40 was started after executing the hazard lamp display of the window (step S206 in FIG. 14) and the predetermined image / color display of the window (step S207 in FIG. 14). If the concentration of the window glass can be increased before starting and running, the order of execution may be varied.

  In addition, even if the concentration of the window is increased when it is determined that the snoozing occurs, a situation where the driver in the snoozing state makes the vehicle forcibly run is also assumed. Therefore, in order to prevent such traveling, the engine controller 10a in the CPU 10 limits the upper limit of the engine speed to the engine speed in an idling state or an idle-up state when using an air conditioner. It is also effective to take measures against inability to run such that the shift is not executed electrically regardless of the operation, and the transmission is controlled to the neutral state when there is a shift operation in the case of an automatic vehicle. And even if such a measure against inability to travel is taken, there will be no problem with the use of air conditioning while parked. In the case of a manual transmission vehicle, neutral control is not possible. However, if it is detected that the vehicle has started to move, the CPU 10 may stop the engine 40.

  Moreover, in the above embodiment, when the dozing determination unit 14 determines that a dozing occurs (YES in step S204 in FIG. 14), the adjustment unit 10b increases the concentration of the window glass (step S205 in FIG. 14). The hazard lamp display of the window (step S206 in FIG. 14) and the predetermined image / color display of the window (step S207 in FIG. 14) were executed, but in order to suppress running in the dozing state, Only high density may be executed, high density of window glass and window hazard lamp display may be used, or high density of window glass and predetermined image / color display of window may be used.

According to the vehicle control apparatus 101 of this embodiment, if it is determined that the driver is falling asleep, the transmittance of the light control glass 110 is adjusted to a high concentration less than a predetermined value, and the vehicle cannot travel. On the other hand, since the start of the engine 40 is not limited, it is possible to use air conditioning. That is, although the engine 40 can be used for cooling and heating, it is not suitable for traveling, so it is possible to effectively suppress the drowsy driving without giving discomfort to the passengers in the vehicle,
In addition, privacy and security are ensured.

  Further, in this embodiment, since the engine speed of the engine 40 is not limited to idling only, the idle-up function at the time of using the air conditioner operates effectively. There is an advantage that no discomfort is given to the passenger.

  When the driver wants to resume driving after the light control glass 110 has been determined to have fallen asleep and the concentration of the light control glass 110 has been increased, the CPU 10 performs the above-described measurement of reflexes and traffic by performing a predetermined operation. A rule test or the like is executed, and if it is determined that there is no problem in driving, the light control glass 110 is returned to a transparent state. Alternatively, the driver may stop the engine and turn on the ignition again, so that the start-time doze driving suppression control may be executed from the beginning.

[2-4-2] Dozing operation suppression control operation at start (2):
Here, a second example of the start-time doze driving suppression control operation will be described.
When the ignition is turned on by the driver, the CPU 10 (the engine controller 10a and the adjusting means 10b) displays a dozing test execution procedure and the like on the display unit 60 before starting the engine as a start-up dozing operation suppression control routine. To do.

  When the driver's face image and driving posture are photographed by the dozing detection means 57 in accordance with the displayed procedure, the photographing result of the dozing detection means 57 is captured by the CPU 10. Then, the dozing determination unit 14 in the CPU 10 registers the driver's face image or driving posture as an initial image (step S1801 in FIG. 18).

  This initial image is used by the dozing determination unit 14 as a criterion for determining whether or not there is a possibility of falling asleep. When the initial image is a driver's face image, the initial value of the degree of eye opening (h1 / w1, h2 / w2) included in the driver's face image described above is employed as the threshold value. Further, if the initial image is a driving posture as viewed from the side of the driver, an initial value of the inclination of the back is adopted as the threshold value.

  However, at this point in time, the driver's face image may have a very small degree of eye opening, or the driving posture may be bent forward or swaying. This is performed (step S1802 in FIG. 18). That is, the dozing determination unit 14 determines whether or not there is a possibility of falling asleep based on the detection result of the driver detected by the dozing detection unit 57, and transmits the determination result to the adjustment unit 10b.

  Note that there are individual differences in the face image and driving posture, such as a small degree of eye opening and a tendency to bend forward. Therefore, in addition to acquiring and determining this image, it is also desirable to measure reflexes and the like in order to determine the driver's consciousness level and physical condition.

  For example, under the control of the CPU 10, the time until the driver actually blinks three times and the interval between each blink after the message “Please continue blinking three times” is displayed on the display unit 60. If the display unit 60 displays a message “please step on the brake pedal” and measures the time until the driver actually steps on the brake pedal 52, or if the display unit 60 has a touch panel In this case, it is possible to determine the driver's consciousness level and physical condition by displaying a traffic rule test on the display unit 60 and making a determination based on the result (correctness of answer, answer time).

In particular, the time until the brake pedal 52 is depressed is desirable because it is possible to detect a state that is not suitable for driving, including abnormalities in the brain and body other than sleeping. It is also desirable to be able to detect conditions unsuitable for driving, such as brain disorders other than snoozing, by testing traffic rules. Also, the interval time during which the brake pedal 52 is repeatedly depressed can be used for detection as well.

  When it is detected that the driver has started the dozing detection means 57 and registered the face image and posture, the detection result of the dozing detection means 57 is taken into the CPU 10. Then, the dozing determination unit 14 in the CPU 10 determines whether or not there is a possibility of dozing from the detection result of the dozing detection unit 57 (steps S1801 and S1802 in FIG. 18).

  Further, the identification means 19 in the CPU 10 identifies each driver based on biometric data such as a fingerprint, a palm print, and a face photograph acquired by the biometric sensor 59. If the data matches the driver's data registered in advance, the driver is registered as the newly registered driver # 1 if there is no matching data (steps S1801 and S1802 in FIG. 18).

That is, whether or not there is a possibility of falling asleep is determined for each driver as necessary, and a history is stored or compared with a past dozing history as described later.
In addition, if there is a face image registered in the past, it is possible to make a doze determination from the current face image as compared with the registered face image.

  Based on the driver's face image and posture detected by the dozing inspection unit 57 and the above reaction time, the dozing determination unit 14 can make a doze / no sleep based on a facial expression, posture, reaction time, and the like. It is determined that there is a property, and the determination result is transmitted to the adjusting means 10b.

  When the dozing determination unit 14 determines that there is no dozing (NO in step S1803 in FIG. 18), the adjusting unit 10b transmits an engine start instruction to the engine controller 10a, and the engine controller 10a starts the engine 40 (FIG. 18). 18 in step S1810). That is, the engine controller 10a that has received an instruction to start the engine drives a cell motor, a fuel injection device, etc. (not shown) to start the engine 40.

On the other hand, if the dozing determination unit 14 determines that there is a possibility of falling asleep (YES in step S1803 in FIG. 18), the current position of the automobile 100 (latitude / longitude information) based on the detection result of the GPS position detection unit 21. ) Belongs to a specific area (area other than on public roads or private roads where the automobile 100 can travel; for example, private land or a parking lot of a convenience store) (step S1804 in FIG. 18). If not only the position but also the speed is set as a determination criterion, whether or not the moving speed (vehicle speed) of the automobile 100 detected by the speed sensor 22 by the speed judging means 12 is zero, that is, the automobile 100 is determined. It is determined whether or not the vehicle is stopped.

  Here, when it is determined by the dozing determination unit 14 that there is a possibility of falling asleep (YES in step S1803 in FIG. 18), the current position (latitude / longitude information) of the automobile 100 is the specific region (the travel of the automobile 100). If the vehicle does not belong to any area other than on public roads or private roads that can move; for example, private land or convenience store parking lots (NO in step S1804 in FIG. 18), or if the speed is other than zero, the engine controller 10a Without starting the engine 40, the adjusting means 10b stores the history of having a doze determination outside the specific area in the storage unit and ends the process (step S1831 in FIG. 18).

That is, according to this control, when the engine of the vehicle is started, the expression / posture / reaction time that is suspected of falling asleep is detected and it is determined that there is a possibility of falling asleep. If so, the transmittance of the light control glass is not adjusted below the specified value, but it is controlled so that the engine is not started, so that it does not violate laws and regulations such as vehicle transport safety standards and is in a legal state. It is possible to effectively suppress the drowsy driving while maintaining.

  Here, when it is determined by the dozing determination unit 14 that there is a possibility of falling asleep (YES in step S1803 in FIG. 18), the current position (latitude / longitude information) of the automobile 100 is the specific region (the travel of the automobile 100). If it belongs to an area other than on a public road or private road that can move; for example, private land or a parking lot at a convenience store (YES in step S1804 in FIG. 18), or the position is a specific area and the speed is zero. If it exists, the transmittance | permeability of each light control glass 110 which comprises at least the window glass 111-113 by the adjustment means 10b, Preferably each light control glass 110 which comprises the window glasses 111-116 is high density (regulated value) by the adjustment means 10b. (Less than (70%)) (step S1805 in FIG. 18). In this case, since it is determined that there is a possibility of falling asleep, it is desirable that each light control glass is controlled to a concentration as high as possible (low transmittance) so that it is substantially impossible to drive.

  In this case, not only when the light control glass 110 is controlled from a transparent state to a high concentration, but also when the state where the light control glass 110 is already in a high concentration state is maintained by the light control operation described with reference to FIGS. 7 and 8. Including. Furthermore, in the case where the concentration is controlled to be higher in order to suppress the drowsy driving from the state where the concentration is already high by the light control operation described with reference to FIGS.

  Further, when it is determined by the dozing determination unit 14 that there is a possibility of falling asleep (YES in step S1803 in FIG. 18), the current position (latitude / longitude information) of the automobile 100 is a specific region (traveling movement of the automobile 100). If it belongs to an area other than on public roads or private roads (eg, private land or a parking lot at a convenience store) (YES in step S1804 in FIG. 18), the adjustment means together with the control for increasing the concentration of the light control glass With the display control function of 10b, as the color display by the organic EL element layer 140 in the light control glass 110 on the front window glass 111 and the rear window glass 116, for example, a hazard lamp display image (right An image including a large right arrow corresponding to both the direction instruction and the left direction instruction is displayed (steps in FIG. 18). S1806). In this case, it is determined that there is a possibility of falling asleep and it is possible to inform the outside that the vehicle cannot travel. Instead of the hazard lamp display, a parking lamp display that is always lit red may be used.

  Furthermore, when it is determined by the dozing determination unit 14 that there is a possibility of falling asleep (YES in step S1803 in FIG. 18), the current position (latitude / longitude information) of the automobile 100 is a specific region (traveling movement of the automobile 100). If it belongs to an area other than on public roads or private roads (eg, private land or a convenience store parking lot) (YES in step S1804 in FIG. 18), control of increasing the concentration of the light control glass and hazard lamp display At the same time, by the display control function of the adjusting means 10b, the data related to the designated image or color is read from the ROM of the storage unit 30 in any one of the window glasses or the entire window glass, and based on the read data. An arbitrary image or a designated color is emitted and displayed on the light control glass 110 (step S1807 in FIG. 18). . In this case, it is desirable to use an image or color that informs the outside that it is determined that there is a possibility of falling asleep and the vehicle cannot travel.

Then, as described above, when it is determined by the dozing determination unit 14 that there is a possibility of falling asleep (YES in step S1803 in FIG. 18), the current position (latitude / longitude information) of the automobile 100 is the specific region ( If the vehicle 100 belongs to an area other than the public road or private road on which the automobile 100 can travel; for example, private land or a parking lot at a convenience store (YES in step S1804 in FIG. 18), the adjusting means 10b has a high concentration of window glass. 18 (step S1805 in FIG. 18), hazard lamp display of the window (step S1806 in FIG. 18), and predetermined image / color display of the window (step S1807 in FIG. 18), the adjustment means 10b starts the engine. The instruction is transmitted to the engine controller 10a, and the engine controller 10a starts the engine 40 (FIG. 18). Of step S1808).

That is, the engine controller 10a that has received an instruction to start the engine drives a cell motor, a fuel injection device, etc. (not shown) to start the engine 40.
Then, the CPU 10 continues the above-described window high-density control, etc., and executes the dozing operation suppression control, and if there is an instruction to stop the engine (YES in step S1809 in FIG. 18), the engine controller 10a causes the engine 40 to operate. The adjustment unit 10b stores the history of a doze determination in the specific area in the storage unit (step S1831 in FIG. 18).

  In the above embodiment, when it is determined that there is a possibility of falling asleep in the specific area by the dozing determination unit 14 (YES in step S1803 in FIG. 18 and YES in S1804), the adjustment unit 10b increases the height of the window glass. After executing the concentration (step S1805 in FIG. 18), the hazard lamp display of the window (step S1806 in FIG. 18), and the predetermined image / color display of the window (step S1807 in FIG. 18), the engine 40 is started ( Although step S1808) in FIG. 18 is performed, the order of execution may be changed almost simultaneously, that is, if the concentration of the window glass can be increased before the engine is started and the vehicle starts running. Further, immediately after the engine is started, the window density may be increased and various displays may be executed. In this case, the burden on the battery can be reduced.

  In addition, even if it is determined that there is a possibility of falling asleep and the concentration of the window is increased, a situation in which the driver in a sleeping state causes the vehicle to forcibly drive is also assumed. Therefore, in order to prevent such traveling, the engine controller 10a in the CPU 10 limits the upper limit of the engine speed to the engine speed in an idling state or an idle-up state when using an air conditioner. It is also effective to take measures against inability to run such that the shift is not executed electrically regardless of the operation, and the transmission is controlled to the neutral state when there is a shift operation in the case of an automatic vehicle. And even if such a measure against inability to travel is taken, there will be no problem with the use of air conditioning while parked. In the case of a manual transmission vehicle, neutral control is not possible. However, if it is detected that the vehicle has started to move, the CPU 10 may stop the engine 40.

  Moreover, in the above embodiment, when the dozing determination unit 14 determines that there is a possibility of falling asleep in a specific area (YES in step S1803 in FIG. 18, YES in S1804), the adjustment unit 10b has a high density of the window glass. (Step S1805 in FIG. 18), hazard lamp display of the window (step S1806 in FIG. 18), and predetermined image / color display of the window (step S1807 in FIG. 18). In order to suppress driving, only the concentration of the window glass may be increased, or the concentration of the window glass and the hazard lamp display of the window may be displayed. Color display may be used.

  According to the vehicle control apparatus 101 of this embodiment, if a facial expression / posture / reaction time that is suspected of falling asleep is detected from the driver's face image, posture, and reaction time, and it is determined that there is a possibility of falling asleep, the light control glass The transmittance of 110 is adjusted to a high concentration below the specified value, and the vehicle cannot run. On the other hand, since the start of the engine 40 is not limited, it is possible to use air conditioning. That is, although the engine 40 can be used for cooling and heating, it is not suitable for traveling, so that it is possible to effectively suppress the drowsy driving without giving uncomfortable feeling to the passengers in the vehicle.

That is, although the engine 40 can be used for cooling and heating, it is not suitable for driving, so it is possible to effectively suppress the drowsy driving without causing discomfort to the occupants in the vehicle, and privacy and security are also improved. Secured.

  Further, in this embodiment, since the engine speed of the engine 40 is not limited to idling only, the idle-up function at the time of using the air conditioner operates effectively. There is an advantage that no discomfort is given to the passenger.

  When the driver wants to resume driving after the light control glass 110 is determined to have a possibility of falling asleep and the concentration of the light control glass 110 is increased, the CPU 10 measures the above-described reflexes by a predetermined operation. The traffic light test glass 110 is returned to a transparent state if it is determined that there is no problem in driving. Alternatively, the driver may stop the engine and turn on the ignition again, so that the start-time doze driving suppression control may be executed from the beginning.

  In this embodiment, the adjusting means 10b accumulates the history of the result of the determination of dozing at the start of the engine, and if the determination that there is a possibility of falling asleep is more than a predetermined number of times, the adjustment means 10b can fall asleep at the start of the engine. Even if it is determined that the vehicle is located and the vehicle location is determined to belong to a specific area, the transmittance of the light control glass is adjusted to be less than the specified value, but the engine is not started. You may control.

  In this case, in order to adjust the transmittance of the window below the specified value in a specific area, it does not violate laws and regulations such as vehicle transport safety standards, while maintaining a legal state and a high concentration of the window. By making the engine and the engine not started, it is possible to effectively suppress the drowsy driving.

  Further, in this embodiment, the adjusting unit 10b identifies the driver based on the detection result of the biosensor 59, and the history of the determination result of the dozing determination unit at the start of the engine is identified for the identified driver. If it is stored and the possibility of falling asleep is more than a predetermined number of times, it is determined that there is a possibility of falling asleep when the engine is started, and the vehicle location is determined to belong to a specific area. However, although the transmittance of the light control glass is adjusted to be less than a specified value, it is possible to control so that the engine is not started. In this case, in order to adjust the transmittance of the window below the specified value in a specific area, it does not violate laws and regulations such as vehicle transport safety standards, while maintaining a legal state and a high concentration of the window. By making the engine and the engine not started, it is possible to effectively suppress the drowsy driving.

  In addition, when a plurality of drivers use the same vehicle alternately, it is desirable to perform the control of the present embodiment after identifying the drivers with the biometric data. On the other hand, in the case of a vehicle used by only one person, it is not necessary to perform driver identification by the biosensor 59.

[2-4-3] Dozing operation suppression control operation during running:
CPU 10 (engine controller 10a and adjusting means 10b) starts the engine (step S210 in FIG. 14) when there is no dozing (NO in step S204 in FIG. 14), and performs a dozing operation suppression control routine during traveling. The following processing is executed.

  Similarly, the CPU 10 (the engine controller 10a and the adjusting means 10b) starts the engine (step S1810 in FIG. 18) when it is not asleep (NO in step S1803 in FIG. 18), and is asleep while traveling. The following processing is executed as an operation suppression control routine. The following description will be given with reference to FIG.

Note that the state where the engine is actually started but has not started traveling is also in a state where traveling can be started, and therefore, here, it will be treated as dozing operation suppression control during traveling.
In the vehicle control apparatus 101 of this embodiment, the dozing detection means 57 detects the dozing from the driving state of the driver (openness of eyes or change in posture) after the engine is started or the vehicle is running (in FIG. 14). Step S211).

When the dozing detection means 57 detects for a certain time, the detection result of the dozing detection means 57 is taken into the CPU 10.
Then, the dozing determination unit 14 in the CPU 10 determines whether or not the driver is falling asleep while driving from the detection result of the dozing detection unit 57 (step S212 in FIG. 14).

  The dozing determination unit 14 determines whether there is no dozing / occurrence of dozing based on the degree of opening of the eyes and the change in posture detected by the dozing detection unit 57, and transmits the determination result to the adjustment unit 10b.

  During driving, the face image and driving posture image may be disturbed due to slight posture changes and left and right confirmations, so both the face image and driving posture may be used, or the average value for a predetermined time It is desirable to determine from the viewpoint of preventing malfunction.

  For example, a state where the degree of opening of the eye is 50% or less at the time of initial registration continues for one second or more. Moreover, if the number of times of forward bending is one or more times per minute and the state continues several times, such as normal and driving posture, it is considered to be asleep. This numerical value is an example, and various modifications and settings are possible.

  When the dozing determination unit 14 determines that there is no dozing (NO in step S213 in FIG. 14), the adjusting unit 10b does not issue a special instruction, and will be described later while maintaining the normal engine control state and running state. Thus, the light control and display control of the window glass are performed.

  On the other hand, when the dozing determination unit 14 determines that a dozing has occurred (YES in step S213 in FIG. 14), the adjusting unit 10b can park and stop the vehicle based on the detection result of the GPS position detection unit 21 and the navigation program. It is determined whether it is located at a certain place (step S214 in FIG. 14).

  Here, being located in a place where parking and stopping is possible means that the position is in a parking lot or private land, and the vehicle is stationary. Even if the vehicle is stationary on the left side of a road where parking is not prohibited, or on the left side of the road where parking on the road is permitted by payment of a ticket or fee, You may determine that

  Further, when the vehicle is traveling on a road (public road, private road), it is determined that the vehicle is not located at a place where parking or stopping is possible. Also, if the vehicle is temporarily stopped due to traffic jam or waiting for traffic lights on the road, it is determined that the vehicle is not located at a place where parking or stopping is possible. Further, even when the vehicle is parked near the end of the road, it is determined that the vehicle is not located in a place where parking can be stopped if parking is prohibited.

  Even in a vast parking lot such as a shopping mall, if the vehicle is moving, it is judged that it is not in a place where parking and stopping is possible, and it is urged to stop in a nearby empty space. .

  In addition, the detection result of the GPS position detection unit 21 is referred to for the vehicle position in the above case, and the detection result of the GPS position detection unit 21 or the vehicle speed sensor (not shown) is detected for the moving speed of the vehicle. Refer to the results.

  Here, if the vehicle is not in a parking / parking location (NO in step S214 in FIG. 14), a search to the nearest parking / parking location is executed (step S215 in FIG. 14). Then, the display unit 60 is guided to the parking and stopping location (steps S216 and S217 in FIG. 14). Alternatively, the CPU 10 instructs a car navigation device (not shown) to search for the nearest parking / stoppable location and guides the vehicle to the parking / parking location (steps S216 and S217 in FIG. 14).

Note that when the vehicle is moving even in the parking lot, the CPU 10 performs control so that a warning message to park in the nearest empty space is continuously displayed while the vehicle is moving.
In addition, it is desirable to perform an alarm sound or display during this guidance in order to prevent further sleep. In addition to this, it is also desirable to apply cool air from the air conditioner to the driver's face and head.

  Then, the position determination unit 11 determines whether the current position (latitude / longitude information) of the automobile 100 detected by the GPS position detection unit 21 belongs to the guidance destination, and the speed determination unit 12 It is determined whether or not the moving speed (vehicle speed) of the automobile 100 detected by the speed sensor 22 is zero, that is, whether or not the automobile 100 is stopped at the guidance destination (step S217 in FIG. 14).

  If the automobile 100 has reached the guidance destination (YES in step S217 in FIG. 14), at least each of the light control glasses 110 forming the window glasses 111 to 113, preferably each of the light control glasses 110 forming the window glasses 111 to 116. Is adjusted to a high density (less than a predetermined value (70%)) by the adjusting means 10b (step S218 in FIG. 14).

  Then, the CPU 10 displays a message prompting the user to operate the shift lever to the parking position on the display unit 60. If the driver does not follow this message, the transmission can be electrically controlled neutral in the case of an automatic vehicle. In the case of a manual vehicle, the engine may be stopped because the vehicle travels and there is a danger.

  In addition, when it is determined that the dozing has occurred by the dozing determination unit 14 (YES in step S213 in FIG. 14), and the vehicle is stopped at a place where parking is possible (YES in step S214 in FIG. 14), That is, even when the user takes a nap after starting the engine in a parking lot or the like, in the same manner, the light control glasses 110 that form at least the window glasses 111 to 113, preferably the window glasses 111 to 116, at that location. 14 is adjusted to a high density (less than a predetermined value (70%)) by the adjusting means 10b (step S218 in FIG. 14).

In the above case, since it is determined that a drowsiness has occurred, it is desirable that each light control glass is controlled to a concentration as high as possible (low transmittance) so that it is substantially impossible to drive.
In this case, not only when the light control glass 110 is controlled from a transparent state to a high concentration, but also when the state where the light control glass 110 is already in a high concentration state is maintained by the light control operation described with reference to FIGS. 7 and 8. Including. Furthermore, in the case where the concentration is controlled to be higher in order to suppress the drowsy driving from the state where the concentration is already high by the light control operation described with reference to FIGS.

In addition, when it is determined that the dozing has occurred by the dozing determination unit 14 (YES in step S213 in FIG. 14) and after reaching the guidance destination (YES in step S217 in FIG. 14), or the dozing determination unit 14 is determined to have fallen asleep (YES in step S213 in FIG. 14), and the vehicle is stopped at a place where parking and stopping is possible (step S21 in FIG. 14).
4), the organic EL element layer 140 in the light control glass 110 in the front window glass 111 and the rear window glass 116 is controlled by the display control function of the adjusting means 10b together with the above control of the concentration of the light control glass. As a color display, for example, a hazard lamp display image (an image including a large right arrow corresponding to both a right direction instruction and a left direction instruction) as shown in FIG. 6B is displayed (step in FIG. 14). S219). In this case, it can be informed to the outside that it is determined that doze has occurred and the vehicle cannot travel. Instead of the hazard lamp display, a parking lamp display that is always lit red may be used.

  Furthermore, when it is determined that the dozing occurs by the dozing determination unit 14 (YES in step S213 in FIG. 14) and after reaching the guidance destination (YES in step S217 in FIG. 14), or the determination of dozing If it is determined that snoozing has occurred in the means 14 (YES in step S213 in FIG. 14) and the vehicle has stopped at a place where parking is possible (YES in step S214 in FIG. 14), the above light control glass The data relating to the designated image or color is read from the ROM of the storage unit 30 in any one of the window glasses or the entire window glass by the display control function of the adjusting means 10b along with the control of the density increase and the hazard lamp display. Based on the read data, an arbitrary image or a specified color is emitted or displayed on the light control glass 110. That (step S220 in FIG. 14). In this case, it is desirable to use an image or a color that informs the outside that it is determined that a drowsiness has occurred and the vehicle cannot travel.

  As described above, when the dozing determination unit 14 determines that a dozing has occurred after the engine is started (YES in step S213 in FIG. 14), the adjustment unit 10b increases the concentration of the window glass (step in FIG. 14). S218) A hazard lamp display of the window (step S219 in FIG. 14) and a predetermined image / color display of the window (step S220 in FIG. 14) are executed, but the adjusting means 10b does not stop the engine.

  That is, the engine controller 10a that has received an instruction to start the engine drives a cell motor or a fuel injection device (not shown) to operate the engine 40, and the engine is stopped by the operation of the ignition switch (in FIG. 14). Until the determination in step S209 is YES, the CPU 10 continues the above-described window density increasing control and the like, and executes the drowsy driving suppression control.

  Even if it is determined that a snooze has occurred and the concentration of the window is increased, a situation where the driver in a snoozing state drives the vehicle forcibly is also assumed. Therefore, in order to prevent such traveling, the engine controller 10a in the CPU 10 limits the upper limit of the engine speed to the engine speed in an idling state or an idle-up state when using an air conditioner. It is also effective to take measures against inability to run such that the shift is not executed electrically regardless of the operation, and the transmission is controlled to the neutral state when there is a shift operation in the case of an automatic vehicle. And even if such a measure against inability to travel is taken, there will be no problem with the use of air conditioning while parked. In the case of a manual transmission vehicle, neutral control is not possible. However, if it is detected that the vehicle has started to move, the CPU 10 may stop the engine 40.

Moreover, in the above embodiment, when the dozing determination unit 14 determines that a dozing has occurred (YES in step S213 in FIG. 14), the adjustment unit 10b increases the concentration of the window glass (step S217 in FIG. 14). The window hazard lamp display (step S218 in FIG. 14) and the predetermined image / color display of the window (step S219 in FIG. 14) were executed. It may be possible to execute only a high density of the window glass, a high density of the window glass and a hazard lamp display of the window, or a high density of the window glass and a predetermined image / color display of the window.

  According to the vehicle control apparatus 101 of this embodiment, if it is determined that a driver's nap is detected and a nap has occurred, the vehicle is guided to a parking / stopping location if the vehicle is not stopped at the parking / stopping location. Later, if it is in a state where it can be parked and stopped, the transmittance of the light control glass 110 is adjusted to a high concentration below a predetermined value on the spot, and the vehicle cannot run. On the other hand, since the start of the engine 40 is not limited, it is possible to use air conditioning. That is, although the engine 40 can be used for cooling and heating, it is not suitable for driving, so it is possible to effectively suppress the drowsy driving without causing discomfort to the occupants in the vehicle, and privacy and security are also improved. Secured.

  Further, in this embodiment, since the engine speed of the engine 40 is not limited to idling only, the idle-up function at the time of using the air conditioner operates effectively. There is an advantage that no discomfort is given to the passenger.

  When the driver wants to resume driving after the light control glass 110 has been determined to have fallen asleep and the concentration of the light control glass 110 has been increased, the CPU 10 performs the above-described measurement of reflexes and traffic by performing a predetermined operation. A rule test or the like is executed, and if it is determined that there is no problem in driving, the light control glass 110 is returned to a transparent state. Alternatively, the driver may stop the engine and turn on the ignition again, so that the start-time doze driving suppression control may be executed from the beginning.

[2-4-4] Dimming control operation:
The CPU 10 (engine controller 10a and adjusting means 10b) starts the engine (step S210 in FIG. 14) when there is no sleep (NO in step S204 in FIG. 14), and if no sleep is detected (FIG. 14). In step S213, NO), a window glass dimming control routine and a display control routine described below are executed.

  Similarly, the CPU 10 (the engine controller 10a and the adjusting means 10b) starts the engine (step S1810 in FIG. 18) when no sleep is detected (NO in step S1803 in FIG. 18), and the sleep is detected. If not (NO in step S1813 in FIG. 18), a window glass dimming control routine and display control routine described below are executed.

  That is, as described above, the CPU 10 (adjusting means 10b) operates in accordance with an instruction from the changeover switch 54, and is a subject of the road transport vehicle security standard (Article 29, Paragraph 4). As for the window glasses 111 to 113 on the front and both sides, the light control of the light control glass 110 is performed according to the flowchart (steps S21 to S20) shown in FIG. 7 (step S221 in FIGS. 14 and 18).

  Moreover, CPU10 performs dimming control of the light control glass 110 according to the flowchart (step S21-S25) shown in FIG. 8 about the other window glasses 114-116 (step S222 in FIG. 14, FIG. 18).

[2-4-5] Display control operation (1):
The CPU 10 (engine controller 10a and adjusting means 10b) starts the engine (step S210 in FIG. 14) when there is no sleep (NO in step S204 in FIG. 14), and if no sleep is detected (FIG. 14). In step S213, NO), following the dimming control described above, a dimming control routine and a display control routine for the window glass described below are executed.

  Similarly, the CPU 10 (the engine controller 10a and the adjusting means 10b) starts the engine (step S1810 in FIG. 18) when no sleep is detected (NO in step S1803 in FIG. 18), and the sleep is detected. If not (NO in step S1813 in FIG. 18), a window glass dimming control routine and a display control routine described below are executed following the dimming control described above.

  That is, as described above, the CPU 10 (the display control function of the adjusting means 10b) is a window glass on the front and both sides of the driver, which is the target of the road transport vehicle safety standard (Article 29, paragraph 4). About 111-113 operate | moves according to the instruction | indication from the display instruction input part 55, and performs display control of the light control glass 110 (organic EL element layer 140) according to the flowchart (step S51-S58) shown in FIG. 14, step S223 in FIG.

  Further, as described above, the CPU 10 (display control function of the adjusting means 10b) displays the light control glass 110 (organic EL element layer 140) for the rear window glass 116 according to the flowchart (steps S31 to S42) shown in FIG. Control is performed (step S224 in FIGS. 14 and 18). Further, as described above, the CPU 10 (the display control function of the adjusting means 10b) uses the light control glass 110 (organic EL element layer) according to the flowchart (steps S61 to S65) shown in FIG. 140) is controlled (step S224 in FIGS. 14 and 18).

  The CPU 10 drives a cell motor or a fuel injection device (not shown) to operate the engine 40 until the engine is stopped by the operation of the ignition switch (YES in step S225 in FIGS. 14 and 18). The detection of dozing (step S213 in FIG. 14), the above-mentioned dimming control (steps S221 and 222 in FIG. 14 and FIG. 18) and display control (steps S223 and 224 in FIG. 14 and FIG. 18) are continued. .

  In this case, when no snoozing is detected, dimming control of the normal window glass (transparent → high density, high density → transparent) and various display controls on the window glass can be executed. If you are stopped at certain locations (such as private property or convenience store parking lots) while keeping safety while parked or while traveling in areas other than public roads, The window glass 111 to 116 can be switched to a high concentration state by switching the transmittance of the window glasses 111 to 116 (light control glass 110) to less than a predetermined value without removing the window, so that the temperature inside the vehicle during the stop increases. As well as privacy and security. Further, since it is not necessary to remove the key, the window glasses 111 to 116 can be switched to a high concentration state while starting the engine 40 and operating the air conditioner or the like during meals or sleep in the automobile 100.

  In addition, while driving, the dozing detection (FIG. 14) is performed while performing the above-mentioned dimming control (steps S221 and 222 in FIGS. 14 and 18) and display control (steps S223 and 224 in FIGS. 14 and 18). Steps S211, S212, and S213) are repeated, and if a drowsiness is detected, guidance to a place where parking is possible (steps S215, 216, and 217 in FIG. 14) and high-concentration control of the window glass for suppressing drowsy driving (Steps S218, 219, and 220 in FIG. 14) are executed, and the effect of suppressing the drowsy driving can be expected.

Further, if the vehicle is stopped at a parking and stopping place after starting the engine and before starting running, the above-mentioned window glass light control (steps S221 and 222 in FIGS. 14 and 18) and display control (FIG. 14 and step S223, 224 in FIG. 18), and dozing detection (steps S211, S212, S213 in FIG. 14) is repeated. The high density control of the window glass and the like (steps S218, 219, and 220 in FIG. 14) are executed, and the effect of suppressing the drowsy driving can be expected.

[2-4-6] Display control operation (2):
The following display operation (2) can be performed instead of or in addition to the above display operation (1).

  Here, in this embodiment, when color display is performed on the window glasses 111 to 116 by the display control function of the adjusting means 10b, it is determined that the location of the automobile 100 belongs to a specific area (an area other than on the public road). Only when it is determined that the moving speed of the automobile 100 is zero, color display by the light control glass 110 (organic EL element layer 140) may be performed in response to the sound of the car audio. .

  In this case, the car audio signal may be input to the adjusting unit 10b, or a microphone or the like (not shown) may be connected to the adjusting unit 10b. In this case, the adjusting means 10b constitutes the image generating means in the claims. Note that a dedicated image generation processor may be provided in order to perform complicated or user-defined display.

  Then, the adjusting unit 10b generates a predetermined image signal from the sound signal with reference to the sound-image conversion program stored in the ROM or the like of the storage unit 30, and displays the image on the light control glass. In this case, it is also possible for a driver or a passenger to select a plurality of patterns.

  In this case, when it is determined that the location of the automobile 100 does not belong to a specific area (that is, for example, belongs to a public road), or when it is determined that the moving speed of the automobile 100 is not zero, It is desirable to cancel the color display.

  Therefore, for example, when the vehicle is stopped on a public road or while it is not on a public road, color display by the window glasses 111 to 113 (light control glass 110) cannot be performed. Therefore, safety during a stop on a public road is possible. And safety during movement in areas other than on public roads.

  And according to this embodiment, the effect display according to the audio signal such as car audio is performed on the glass, so that the vehicle is stopped, and the vehicle is in a state where it cannot enjoy traveling while enjoying music while the vehicle is stopped. You can let others know. Since this effect display uses glass, a powerful display with a larger screen than the display of the car audio device is possible, and safety and legality are ensured.

  Note that the image display as the effect display using the light emitting layer such as the organic EL layer 143 may be an image display using a plurality of pixels in a matrix shape, or a change in light emission state or a change in density on the entire glass surface. May be displayed. Alternatively, a display in which the organic EL light emitting layer 143 having a predetermined shape is provided not on the entire glass surface but on a part of the glass surface and the light emission state or density of the shape is changed may be used.

  Further, the image display as the effect display using the light emitting layer such as the organic EL layer 143 may be a display using the three primary colors of RGB, a monochromatic display, or a monochrome display.

  Further, even if the adjusting means 10b controls the image display as the effect display using the light emitting layer such as the organic EL layer 143 to be an effect display in a different state depending on the presence or absence of the possibility of falling asleep. Good.

Moreover, you may use the change of the density | concentration of the light control glass 110 for the image display as an effect display, without using the organic EL layer 143. FIG.
[3] Effects of the vehicle control device of this embodiment:
In the above embodiment, when the engine is started, when it is determined that the driver is likely to fall asleep by the dozing determination unit, and the position determination unit determines that the location of the automobile 100 belongs to the specific region, The transmittance of the light control glass 110 of the window is adjusted to be less than the specified value, and the engine is started. That is, according to this vehicle control device 101, when the engine of the automobile 100 is started, if the suspicion of dozing is detected from the driver's facial expression, posture, reaction time, etc., and it is determined that there is a possibility of falling asleep, the light control glass 110 The transmittance is adjusted below the specified value. Therefore, if the driver of the automobile 100 has a possibility of falling asleep, the transmittance of the window glass (the light control glass 110) is less than the specified value, which is not suitable for running.

  On the other hand, since the start of the engine is not limited, air conditioning or the like can be used. That is, although the engine can be started and used for cooling and heating, it is not suitable for traveling, so that it is possible to effectively suppress the drowsy driving without giving discomfort to the passengers in the automobile 100. Furthermore, since this control is executed at the time of start-up, the automobile 100 cannot be moved from the parked and stopped position, and it becomes possible to effectively suppress the drowsy driving.

  In addition, in order to adjust the window transmittance to less than the specified value when it is in a specific area, it effectively suppresses snoozing while maintaining a legal state without violating laws and regulations such as vehicle transport safety standards. It becomes possible.

  In the above embodiment, at the time of starting the engine, it is determined that the driver is likely to fall asleep by the dozing determination unit, and the position determination unit determines that the location of the automobile 100 belongs to a specific region and the speed is zero. Is determined, the transmittance of the light control glass 110 of the window is adjusted to be less than the specified value, and the engine is started. Here, the specific area is an area other than a road (public road or private road) on which the automobile 100 can travel, that is, private land.

  According to this vehicle control device 101, when the engine of the automobile 100 is started, if the suspicion of dozing is detected from the driver's facial expression, posture, reaction time, etc., and it is determined that there is a possibility of falling asleep, the transmittance of the light control glass 110 Is adjusted below the specified value. Therefore, if the driver of the automobile 100 has a possibility of falling asleep, the transmittance of the window glass (the light control glass 110) is less than the specified value, which is not suitable for running.

  On the other hand, since the start of the engine is not limited, air conditioning or the like can be used. That is, although the engine can be started and used for cooling and heating, it is not suitable for traveling, so that it is possible to effectively suppress the drowsy driving without giving discomfort to the passengers in the automobile 100. Furthermore, since this control is executed at the time of start-up, the automobile 100 cannot be moved from the parked and stopped position, and it becomes possible to effectively suppress the drowsy driving.

  In addition, in order to adjust the window transmittance to less than the specified value when it is in a specific area, it effectively suppresses snoozing while maintaining a legal state without violating laws and regulations such as vehicle transport safety standards. It becomes possible.

  Therefore, for example, when the vehicle is stopped on the road or moving even if it is not on the road, the transmittance of the window glasses 111 to 113 (light control glass 110) cannot be switched to less than the specified value. Since 113 cannot be switched to a high concentration state, safety during stopping on public roads and safety during movement in areas other than public roads and private roads can be ensured.

  In the above embodiment, the control means determines that there is a possibility of falling asleep at the start of the engine by the dozing determination means, and the position determination means determines that the location of the automobile 100 is the specific area (private land other than public roads / private roads). If it is determined that the light does not belong to the region), the transmittance of the light control glass 110 is not adjusted below the specified value, and the engine is not started. According to this vehicle control device 101, when the suspicion of dozing is detected from the driver's facial expression, posture, reaction time, etc. when the engine of the automobile 100 is started, it is determined that there is a possibility of falling asleep. If it is on the road, the transmittance of the light control glass 110 is not adjusted below the specified value, but it is controlled so as not to start the engine, so that it does not violate laws and regulations such as safety standards for vehicle transportation. It is possible to effectively suppress the drowsy driving while maintaining a safe state.

  Further, in the above embodiment, the history of the determination result of the dozing determination unit at the time of starting the engine is accumulated, and if the determination of the possibility of falling asleep is more than a predetermined number of times, there is a possibility of falling asleep at the start of the engine When it is determined that the location of the automobile 100 belongs to the specific region, the transmittance of the light control glass 110 is adjusted to be less than a specified value, but the engine is not started. In this case, in order to adjust the window transmittance below the specified value in a specific area, it effectively suppresses dozing while maintaining a legal state without violating laws and regulations such as vehicle transportation safety standards. It becomes possible to do.

  In the above embodiment, the driver is identified based on the detection result of the biosensor 59, and a history of determination results of the dozing determination unit at the time of starting the engine is accumulated for the same identified driver. If the determination of the possibility of falling asleep is more than a predetermined number of times, it is determined that there is a possibility of falling asleep when the engine is started, and the light control glass is determined if the location of the automobile 100 is determined to belong to a specific area. Although the transmittance of 110 is adjusted to be less than a specified value, control is performed so that the engine is not started. In this case, in order to adjust the window transmittance below the specified value in a specific area, it effectively suppresses dozing while maintaining a legal state without violating laws and regulations such as vehicle transportation safety standards. It becomes possible to do.

  While securing safety in this way, in specific places other than on public roads and private roads (for example, private land and convenience store parking lots), the windows 111 to 116 (without removing the key if stopped) ( Since the transmittance of the light control glass 110) can be switched to less than the specified value and the window glasses 111 to 116 can be switched to a high concentration state, it is possible to reliably suppress an increase in the temperature inside the vehicle while it is stopped, as well as privacy and security. It can be reliably protected. Further, since it is not necessary to remove the key, the window glasses 111 to 116 can be switched to a high concentration state while starting the engine 40 and operating the air conditioner or the like during meals or sleep in the automobile 100.

  Here, when the light control glass 110 including the liquid crystal film 150 (the light control glass 110A shown in FIG. 2) is used, only a predetermined voltage is applied between the two transparent electrodes 153 and 154. The transmittance of the light control glass 110A can be very easily switched to less than a predetermined value, and the window glasses 111 to 116 can be brought into a high concentration state.

When the light control glass 110 includes the organic EL element layer 140 and the photochromic glass layer 160 (the light control glass 110B shown in FIG. 3), the organic EL element layer 140 is used.
By simply emitting light of a specific wavelength (ultraviolet light) to the light emitting layer 145, the transmittance of the light control glass 110B can be very easily switched to less than a predetermined value to bring the window glasses 111 to 116 into a high concentration state. it can. At this time, since the photochromic glass layer 160 is colored by the light emitted from the organic EL element layer 140, the light transmittance is sufficiently changed, while light other than the light having a wavelength that colors the photochromic glass layer 160 is organic. When the EL element layer 140 emits light, the light control glass 110B including the organic EL element layer 140 can function as a display device for the outside as described above.

  When the light control glass 110 including only the organic electroluminescence element layer 140 (light control glass 110C shown in FIG. 4) is used, the light emitting layer 145 of the organic EL element layer 140 only emits light of a predetermined color. Thus, the transmittance of the light control glass 110C can be very easily switched to less than a predetermined value, and the window glasses 111 to 116 can be brought into a high concentration state. Also in this case, the light control glass 110C including the organic EL element layer 140 can be functioned as a display device for the outside as described above.

  In addition, the light emitting layer 145 in the organic EL element layer 140 is configured by regularly arranging light emitters that emit three primary colors of red, green, and blue in a matrix shape, and controls the light emission state of each light emitter. Thus, it becomes possible to perform arbitrary color development and arbitrary image display in the organic EL element layer 140, and the window glasses 111 to 116 (light control glass 110) can be used as a display device for the outside.

  For example, by making the colors of all the window glasses 111 to 116 (light control glass 110) the same color as the outer surface of the vehicle body while the automobile 100 is stopped or parked, the appearance is stylish and extremely conspicuous. It becomes difficult for a third party with a breach to perform illegal activities such as theft, which greatly contributes to the prevention of illegal activities on the automobile 100.

  In addition, in the organic EL element layer 140 of the light control glass 110 used as the rear window glass 116 while the automobile 100 is traveling, the display linked to the operation of the brake pedal 52 of the automobile 100 and the direction indicator operation unit 53 of the automobile 100 are displayed. By executing the display in conjunction with the operation, not only the brake lamps and turn signals, but also the large display using the rear window glass 116, the driver's willingness to brake and move in the rear is clearly shown It becomes possible to convey, and safety during traveling can be improved.

  In recent years, by using the GPS function of a car navigation system generally installed in automobiles and the like, the location (current position) of the automobile 100 can be determined very easily without newly providing special position detection means. Can be detected.

  Further, according to the road transport vehicle safety standard (Article 29, Paragraph 4), the window glasses 111 to 113 at least in front of and on both sides of the driver may be targeted for transmittance adjustment. About the transmittance | permeability of the light control glass 110 used as window glass 114-116 other than 111-113, regardless of the stop position / movement of the motor vehicle 100, and irrespective of the location of the motor vehicle 100, it is predetermined by the changeover switch 54. By being configured to be selectively switchable to any one of less than or above the values, the window glasses 114 to 116 other than the target window glasses 111 to 113 are switched between transparent / high density depending on the will of the occupant of the automobile 100. It can be performed at any time, and convenience can be improved.

Further, by adjusting the transmittance of the light control glass 110 according to the brightness of the exterior of the automobile 100, the visibility can be secured by increasing the transmittance when the exterior of the automobile 100 is dark, while the exterior of the automobile 100 When the vehicle is extremely bright (such as when there is a lot of ultraviolet rays), the transmittance can be lowered to reduce the glare experienced by the driver and the occupant. Can be improved and safety can be improved.

  Moreover, in this embodiment, when performing a color display in the window glasses 111-113 which are the object of the said road transport vehicle security standard (Article 29 Clause 4) by the display control function of the adjustment means 10b, The color by the light control glass 110 (organic EL element layer 140) is determined only when the location is determined to belong to a specific area (area other than on the public road) and the moving speed of the automobile 100 is determined to be zero. While the display is performed, when it is determined that the location of the automobile 100 does not belong to a specific area (that is, for example, belongs to a public road), or when the moving speed of the automobile 100 is determined to be not zero The color display is canceled and adjusted. Therefore, for example, when the vehicle is stopped on a public road or while it is not on a public road, color display by the window glasses 111 to 113 (light control glass 110) cannot be performed. Therefore, safety during a stop on a public road is possible. And safety during movement in areas other than on public roads.

  Moreover, according to the vehicle control apparatus 101 of this embodiment, if it is determined that the driver is falling asleep, the transmittance of the light control glass 110 is adjusted to a high concentration less than a predetermined value, and the vehicle cannot travel. On the other hand, since the start of the engine 40 is not limited, it is possible to use air conditioning. That is, although the engine 40 can be used for cooling and heating, it is not suitable for driving, so it is possible to effectively suppress the drowsy driving without causing discomfort to the occupants in the vehicle, and privacy and security are also improved. Secured.

  Further, in this embodiment, since the engine speed of the engine 40 is not limited to idling only, the idle-up function at the time of using the air conditioner operates effectively. There is an advantage that no discomfort is given to the passenger.

  Furthermore, according to the vehicle control apparatus 101 of this embodiment, if it is determined that a nap is detected and a nap occurs, the light transmittance of the light control glass 110 is a high concentration less than a predetermined value after being guided to a parking and stopping location. It will be adjusted to be unable to run. On the other hand, since the start of the engine 40 is not limited, it is possible to use air conditioning. That is, although the engine 40 can be used for cooling and heating, it is not suitable for driving, so it is possible to effectively suppress the drowsy driving without causing discomfort to the occupants in the vehicle, and privacy and security are also improved. Secured. Further, in this embodiment, since the engine speed of the engine 40 is not limited to idling only, the idle-up function at the time of using the air conditioner operates effectively. There is an advantage that no discomfort is given to the passenger.

In addition, according to the vehicle control device 101 of this embodiment, when dozing operation suppression control (starting dozing operation suppression control and traveling dozing operation suppression control), dimming control, and display control are executed as a series of controls. Even if there is a drowse occurrence for the driver at the start, the transmittance of the light control glass 110 is adjusted to a high concentration less than a predetermined value, and the vehicle cannot be driven, but the start of the engine 40 is not limited. It becomes possible to use air conditioning, and if a drowsiness is detected in a vehicle that is not located in a parking and stopping place and it is determined that a dozing occurs, after guiding to the parking and stopping place, the light control glass 110 Although the transmittance is adjusted to a high concentration less than a predetermined value and the vehicle cannot run, the start of the engine 40 is not limited, so that air conditioning can be used. In addition, since the detection of dozing is repeated while performing dimming control and display control of the window glass, if a drowsiness is detected, guidance to a place where parking can be stopped and high concentration control of the window glass for suppressing dozing operation should be performed. Therefore, it is possible to expect the effect of suppressing drowsy driving. Further, if a doze is detected from a vehicle located at a parking and stopping place before the start of running after the engine is started and it is determined that a doze occurs, the transmittance of the light control glass 110 on the spot is less than a predetermined value. However, since the start of the engine 40 is not restricted, it is possible to use air conditioning.

[4] Other:
The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

[4-1] Various modifications:
In the above description, the snoozing detection means 57 has been described as a specific example in which the driver's eye opening degree and driving posture are imaged with a camera. With reference to the detection result of the GPS position detection unit 21, the vehicle The state of meandering can be used for snoozing detection. In this case, reference is made to the map data, and the data of the operation angle normalized to the state in which the vehicle should go straight by subtracting the degree of curve from the steering operation angle is used. Further, in order not to be affected by a lane change such as overtaking, the steering angle data when the turn signal is operated is not used. If there is a sign that the operation angle periodically changes to right / left, the dozing determination unit 14 determines that a dozing has occurred. Further, not only meandering but also a sudden steering operation during dozing different from the normal steering operation, the dozing determination means 14 similarly determines that a dozing has occurred.

Further, as the dozing detection means 57, it is possible to use an electroencephalogram detection means for detecting a driver's electroencephalogram instead of a camera that performs imaging.
In that case, the dozing determination unit 14 performs determination based on the difference in the ratio of the alpha wave, beta wave, and theta wave of the driver's brain wave. For example, if there is a large proportion of theta waves that are likely to occur during sleep, it is determined that there is a possibility of falling asleep.

In this case, it is also possible to register the brain wave ratio for each driver in a state where there is no possibility of falling asleep, and to compare it with the registered brain wave state.
Further, it is also possible to use a combination of a camera that captures the degree of opening of the driver's eyes and the driving posture, and an electroencephalogram sensor.

  When the driver's eyes are closed for a long time and the dozing situation becomes worse, the dozing determination means 14 determines that the driver's eyes will not be guided to a place where the vehicle can be parked or parked. After displaying on the display unit 60 so as to stop, the hazard lamp display of the window may be promptly performed after the vehicle is positioned on the road shoulder and the moving speed of the vehicle is determined to be zero.

  Further, for example, in the present embodiment, the case where the vehicle is an automobile has been described. However, the present invention is not limited to this, and a ship such as a cruiser or a small boat, an aircraft, or a window glass such as a train. If it is a certain vehicle, this invention is applied similarly to embodiment mentioned above, and can obtain the effect similar to embodiment mentioned above.

  When no color display or the like is performed, each light control glass 110 is configured by attaching only a liquid crystal film 150 as shown in FIG. 2 to a normal glass plate that does not have the organic EL element layer 140. In addition, the CPU 10 is configured to function as the position determination unit 11, the speed determination unit 12, and the adjustment unit 10b. The adjustment unit 10b transmits the light control glasses 110 through the procedure described with reference to FIGS. You may comprise so that a rate may be adjusted.

According to such a configuration, color display by the organic EL element layer 140 cannot be performed, but the vehicle 100 is stopped at a specific place other than on the public road while ensuring safety during the stop on the public road, for example. If this is done, the window can be switched to a high-density state without removing the key, and the above-mentioned effects of the present invention can be obtained.

  In the present embodiment, six light control glasses 110 are used, but the present invention is not limited to this, and the number of window glasses used in a vehicle equipped with the vehicle control device 101 of the present invention. Minute dimming glass 110 is used.

  Further, the light control glass 110 may not be entirely composed of one organic EL panel, and a plurality of organic EL panels may be combined to form one light control glass 110. With this configuration, even if a large organic EL panel is difficult to obtain due to technical or economic reasons, the light control glass 110 made of the organic EL panel can be enlarged. It is.

[4-2] Modified example of control operation for suppressing drowsy operation at start-up:
A description will be given of a modified example shown in the flowchart of FIG. 19 with respect to the drowsy driving suppression control operation (the operation of the engine controller 10a and the adjusting means 10b) at the start of the vehicle control device 101 described above.

  Here, it is assumed that the automobile is already parked or stopped in a specific area such as private land, and the window exists in a state where a high concentration state of a predetermined value (less than a specified value) is maintained. This increase in concentration may be due to suppression of drowsy driving or may be based on a setting operation for avoiding solar radiation or ensuring privacy.

In FIG. 19, the same steps as those in the flowchart of FIG.
When the dozing determination unit 14 determines that there is no possibility of falling asleep (NO in step S1703 in FIG. 19), the transmittance of each light control glass 110 forming each window glass 111 to 116 is reduced by the adjusting unit 10b. It is adjusted to (specified value (70%) or more) (step S1712 in FIG. 19). Thereby, it will be in the state suitable for normal driving operation.

  Further, the adjusting means 10b transmits an engine start instruction to the engine controller 10a, and the engine controller 10a starts the engine 40 (step S1708 in FIG. 19). That is, the engine controller 10a that has received an instruction to start the engine drives a cell motor, a fuel injection device, etc. (not shown) to start the engine 40.

  Then, if there is an instruction to stop the engine (YES in step S1709 in FIG. 19), the engine controller 10a stops the engine 40 (step S1710 in FIG. 19), and the adjusting means 10b displays a history of no dozing possibility determination. The data is stored in the storage unit (step S1711 in FIG. 19).

On the other hand, if the dozing determination unit 14 determines that there is a possibility of falling asleep (YES in step S1703 in FIG. 19), the current position (latitude / longitude information) of the automobile 100 is determined based on the detection result of the GPS position detection unit 21. ) Belongs to a specific area (an area other than a public road or a private road on which the automobile 100 can travel; for example, a private land or a convenience store parking lot) (step S1704 in FIG. 19).

If not only the position but also the speed is set as a determination criterion, whether or not the moving speed (vehicle speed) of the automobile 100 detected by the speed sensor 22 by the speed judging means 12 is zero, that is, the automobile 100 is determined. It is determined whether or not the vehicle is stopped.

  Here, when it is determined by the dozing determination unit 14 that there is a possibility of falling asleep (YES in step S1703 in FIG. 19), the current position (latitude / longitude information) of the automobile 100 is the specific region (the travel of the automobile 100). If it does not belong to any area other than on public roads or private roads that can move; for example, private land or convenience store parking lots (NO in step S1704 in FIG. 19), or if the speed is other than zero, each window glass The transmittance of each of the light control glasses 110 forming 111 to 116 is adjusted to a low density (specified value (70%) or more) by the adjusting means 10b (step S1713 in FIG. 19).

  Then, the engine controller 10a does not start the engine 40, and the adjusting unit 10b stores the history of the possibility of falling asleep outside the specific area in the storage unit and ends the process (step S1711 in FIG. 19).

  That is, according to this control, when it is determined that there is a possibility of falling asleep from the driver's facial expression, posture, reaction time, etc. when the vehicle engine is started, it is determined that there is a possibility of falling asleep. If it is, the transmittance of the light control glass is set to a low concentration state without making it less than the specified value, but since it is controlled not to start the engine, it does not violate laws and regulations such as safety standards for vehicle transportation, It becomes possible to effectively suppress the drowsiness driving while maintaining a legal state.

  Here, when it is determined by the dozing determination unit 14 that there is a possibility of falling asleep (YES in step S1703 in FIG. 19), the current position (latitude / longitude information) of the automobile 100 is the specific region (the travel of the automobile 100). If it belongs to a region other than on public roads or private roads that can move; for example, private land or a convenience store parking lot (YES in step S1704 in FIG. 19), or the position is a specific region and the speed is zero If it exists, the transmittance | permeability of each light control glass 110 which comprises at least the window glass 111-113 by the adjustment means 10b, Preferably each light control glass 110 which comprises the window glasses 111-116 is high density (regulated value) by the adjustment means 10b. (Less than (70%)) remains adjusted (step S1705 in FIG. 19). Accordingly, it is possible to effectively suppress the drowsy driving while maintaining a legal state without violating laws and regulations such as safety standards for vehicle transportation.

  In this case, the light control glass 110 suppresses the drowsy driving suppression not only when the high concentration is maintained but also from the state where the concentration is already high by the light control operation described in FIG. 7 and FIG. Therefore, an aspect such as when the concentration is controlled to be higher is conceivable.

  Here, the modification corresponding to the flowchart of FIG. 12 has been described with reference to the flowchart of FIG. 19, but this modification can also be applied to the embodiment described with reference to the flowcharts of FIGS. is there.
