JP 2000-6687 A

  When the operation panel as described above is provided in the vehicle interior, if the user is willing to operate the remote control unit, the operating hand can be reliably displayed on the screen of the display device. While it is important from the viewpoint of operability, when there is no intention to operate, the display of hand images is meaningless, so it is desirable not to perform such useless display processing.

  An object of the present invention is to provide an operation input device for a vehicle that can reliably display the operating hand only when the user has an intention to operate.

Means for Solving the Problems and Effects of the Invention

In order to solve the above-described problems, an operation input device for a vehicle according to the present invention includes:
Display means for displaying an operation screen for operating a device provided in the vehicle, and a remote operation surface provided at a position different from the display screen for remotely performing operation input on the operation screen A remote operation unit, hand image photographing means for photographing an image of a hand facing the remote operation surface, and a hand image photographed at a position on the display screen instructed by the hand. A position instruction image display means for displaying the position instruction image, and a vehicle operation input device comprising:
Proximity level detection means for detecting the proximity level between the photographed hand and the remote control unit;
When the detected proximity level exceeds a predetermined operation reception level, the display of the position indication image is permitted while the position is not separated from the operation reception level. Position indication image display control means for prohibiting display of the indication image;
Traveling state detecting means for detecting the traveling state of the vehicle;
Operation reception level changing means for changing the operation reception level according to the detected traveling state;
It is characterized by providing.

  According to the configuration of the present invention, since the position instruction image is not displayed unless the user has a willingness to operate and brings his / her hand closer to the remote operation surface, a useless display of the position instruction image can be omitted. Furthermore, in the vehicle operation input device, there are scenes that should be limited in operation and scenes that should support the operation depending on the running state. According to the configuration of the present invention, since the position indication image can be easily displayed or difficult to display depending on the traveling state, it is possible to switch the operation input device that is easy to use according to the traveling state. realizable.

  The traveling state detection means is a vehicle speed detection means for detecting the vehicle speed of the vehicle, so that the traveling state relating to the vehicle speed can be specified, and the display / non-display of the position instruction image can be switched according to the vehicle speed. Become.

  The operation acceptance level changing means of the present invention is a low speed that does not exceed the reference vehicle speed level when the running condition detecting means detects that the vehicle is in a high speed running state that exceeds a predetermined reference vehicle speed level. When it is detected that the vehicle is in the running state, the operation reception level can be set low. According to this configuration, when the vehicle is traveling at high speed, the operation reception level can be set at a position close to the remote operation unit so that the position instruction image is not easily displayed to limit the operation of the remote operation unit. Further, when the vehicle is traveling at a low speed, the operation reception level can be set at a position far from the remote control unit so that the position instruction image can be easily displayed, so that the operation can be performed smoothly.

  The operation acceptance level changing means of the present invention sets the operation acceptance level lower when the running state detecting means detects that the vehicle is in a stopped state than when the running state is detected as running. it can. According to this configuration, in the traveling state of the vehicle, the operation reception level can be set at a position close to the remote operation unit so that the position instruction image is not easily displayed so as to restrict the operation of the remote operation unit. In addition, when the vehicle is stopped, the operation reception level can be set at a position far from the remote control unit so that the position instruction image can be easily displayed, so that the operation can be performed more smoothly.

  The operation acceptance level changing means according to the present invention is configured so that the vehicle state that does not exceed the reference vehicle speed level is higher than the case where the running state of the vehicle is in a high-speed driving state that exceeds a predetermined reference vehicle speed level by the driving state detection means. When the vehicle is running at a low speed, the operation acceptance level can be set high. According to this configuration, when the vehicle is traveling at high speed, the operation reception level is set to a position close to the remote control unit so that the position indication image can be easily displayed, so that even a traveling driver can easily perform the operation. Thus, the operation can be facilitated. Further, when the vehicle is traveling at a low speed, the operation reception level can be set at a position far from the remote operation unit so that the position instruction image is displayed only when there is an intention to operate.

  The operation acceptance level changing means of the present invention can set the operation acceptance level higher when the running state of the vehicle is stopped than when the running state of the vehicle is running. According to this configuration, when the vehicle is traveling at high speed, the operation reception level is set to a position close to the remote control unit so that the position indication image can be easily displayed, so that even a traveling driver can easily perform the operation. Thus, the operation can be facilitated. Further, when the vehicle is stopped, the operation reception level can be set at a position far from the remote control unit so that the position instruction image is displayed only when there is an intention to operate.

  In the present invention, it is possible to provide hand movement direction detecting means for detecting the direction of movement of the hand imaged by the hand image photographing means in the approach / separation direction to the remote control unit. In this case, the operation reception level changing means can change the operation reception level according to the direction of movement of the hand photographed by the hand image photographing means in the approach / separation direction to the remote operation unit. . When the hand is positioned near the operation acceptance level, there is a possibility that useless processing is repeated such as displaying or disappearing the position instruction image. The movement of the hand in the approach / separation direction to the remote control unit is likely to reflect the user's intention to operate, so the user operation can be changed by changing the operation acceptance level according to the movement direction. It is possible to make it easier to display the position indication image when there is a high possibility of intention, and to make it difficult to display otherwise. Thereby, useless display of the position indication image can be suppressed.

  The operation acceptance level changing means of the present invention is a case where the hand photographed by the hand image photographing means is moving away from the remote operation part, than when the hand is moving closer to the remote operation part. The operation acceptance level can be set high. When the hand facing the remote control unit moves away from the remote control unit, it can be determined that there is no intention to operate. Therefore, when moving away from the remote control unit, it is difficult to display the position indication image by setting the operation acceptance level high. By doing so, useless display of the position indication image can be suppressed. Further, there is no area where wasteful processing is repeated such as displaying or disappearing the position indication image.

  In the present invention, the proximity level detecting means detects a distance between the hand imaged by the hand image photographing means and the remote control unit, and the position indicating image display control means is adapted to detect the distance. A predetermined distance threshold value is used as the operation reception level, and the operation reception level changing means can change the distance threshold value to be longer in the low-speed driving state than in the high-speed driving state of the vehicle. . According to this configuration, the distance between the remote control unit and the hand operating the remote control unit is detected, and the operation reception level (distance threshold) determined for the distance is variable according to the running state; Become. By comparing the threshold value that is changed according to the running state and the detected distance, it is possible to easily change the ease of displaying / the difficulty of displaying the position indication image.

  Further, in the present invention, the proximity level detection means detects a value reflecting the distance between the hand imaged by the hand image imaging means and the remote operation unit, and the position indication image display control means The detection threshold value determined for the detection value is fixedly used as the operation reception level, and the operation reception level changing unit is provided between the hand photographed by the hand image photographing unit and the remote operation unit. When the distance is the same, the predetermined detection condition is changed so as to increase or decrease the detection value detected by the proximity level specifying means, and the value after the distance conversion of the detection value threshold is changed. By doing so, the operation acceptance level can be changed. According to this configuration, it is possible to easily change the operation reception level determined for the distance between the remote operation unit and the hand by simply changing the detection condition without changing the detection threshold.

  By the way, the display means of the present invention is arranged in a vehicle interior so that the display screen is provided at a position different from the remote operation unit and the user who is seated on a seat capable of operating the remote operation unit can view the screen. In addition, an operation image can be displayed on the display screen. In this case, the remote operation unit is configured as an operation unit capable of remotely inputting an operation to an operation image displayed on the screen of the display device based on the touch operation on the operation panel. According to this configuration, an operation image (such as an operation icon) displayed on a display device provided at a position with higher visibility can be operated by a remote operation unit located at hand. For example, when the operator is a driver, if the display screen of the display device is positioned on the front side of the vehicle, the visibility is high, and the remote touch operation while visually recognizing it is easy to perform smoothly.

  In addition, the remote control unit according to the present invention can be a control unit that is fixedly arranged at a position where the vehicle occupant can be operated in a state of being seated on the back of the vehicle seat and is provided separately. It may be fixedly arranged at a position closer to a predetermined seat than the main operation unit (for example, on the display screen or around the display screen).

  Further, the display means in the present invention can be arranged at the front side of the vehicle relative to the vehicle occupant so that the screen can be seen by at least the vehicle occupant seated in the driver's seat of the vehicle. Further, when the main operation unit is provided, a touch panel (display surface contact type operation unit) provided on the display screen of the display unit may be provided as the main operation unit, and the remote operation unit may be It can be provided between the seat of the driver seat and the seat of the passenger seat.

  Note that the pressing operation unit and the operation panel in the present invention can be used as an operation unit of an in-vehicle electronic device, for example, an air conditioner operation unit, an audio operation unit, a navigation operation unit, a power window operation unit, and a seat position adjustment operation unit. Of these, one or more of them can be used together.

  Hereinafter, a first embodiment of a vehicle operation input device of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of a vehicle operation input device of the present invention. In the present embodiment, the remote control unit 10, the display device 20, the vehicle speed sensor 30, and the external storage device 40 are connected to the control unit 100.

  The display device 20 is a known color display device (liquid crystal display, plasma display, organic EL display, etc.), and a plurality of types of operations for displaying operation images such as switch images (operation icons) for touch operation on the display screen. It can be displayed by switching the screen. The display device 20 of the present embodiment includes a touch panel 22 that is a display surface contact type operation unit arranged on a display screen, and switches 21 arranged around the display screen. Yes. Further, the display device 20 of the present embodiment can be visually recognized from both vehicle occupants seated in the driver's seat 2D and the passenger seat 2P, and the touch panel 22 and the switches 21 can be operated from both vehicle occupants. The seats 2D and 2P are arranged on the vehicle front side.

  The touch panel 22 is mounted on the screen of the display device 20 and has a transparent operation panel (for example, a resistive touch switch) arranged in such a manner that the main surface 22a1 exposed in the vehicle interior serves as a touch operation surface. It is configured as a part. The touch operation position made on the touch operation surface 22a1 is detected, and a touch operation input signal reflecting the touch operation position is output to the control unit 100.

  The remote operation unit 10 is an auxiliary operation unit for remotely performing an operation input on the operation image displayed on the display device described above, and includes a touch operation unit 12 and a pressing operation unit 11. Has been. In other words, the remote operation unit 10 is an auxiliary operation unit that can be operated in place of the operation units 22 and 21 of the display device 20 as a main operation unit, and the operation load is smaller than those of the main operation units 22 and 21. Located closer to the user. As shown in FIGS. 2 and 3, the remote operation unit 10 here is configured so that a user seated in the driver's seat 2D and the passenger seat 2P can operate while sitting, It is provided in the center console CB located between the seat portion of the passenger seat 2P. More specifically, the remote control unit 10 is fixedly arranged at a position closer to the passenger of the seat than the display device 20. Furthermore, the center console CB is provided in a region on the front side of the vehicle in a region sandwiched between the seat 2D1 of the driver's seat 2D and the seat 2P1 of the passenger seat 2P.

  As shown in FIG. 4, the remote control unit 10 of the present embodiment is provided with a mounting table 14 having a curved shape for placing a hand to be operated, and the placed hand is curved. To fit. And the touch operation part 12 (touch operation surface 12a1) and the press operation part 11 are arrange | positioned in the vehicle front side position where the finger | toe of the hand placed on the mounting base part 14 will be located. More specifically, the pressing operation unit 11 is disposed on the vehicle rear side with respect to the touch operation unit 12. For this reason, the touch operation unit 12 (touch operation surface 12a1) is located farther from the shoulder position of the person to be operated (here, the driver and the passenger on the passenger seat) than the press operation unit 11, and the press operation unit 11 The position is easier to operate. In addition, as shown in FIG. 5, a recess 13 is formed in a region on the vehicle rear side adjacent to the pressing operation unit 13 on the vehicle rear side so that the operation to the pressing operation unit 11 is easy.

  The pressing operation unit 11 is a switch such as a push switch or a seesaw switch that is disposed close to the operation panel 12a and outputs a pressing operation input signal when it is detected that the operation knob has caused a predetermined displacement by the pressing operation. . The control unit 100 that receives the pressing operation input signal functions as a control execution unit that executes the corresponding control based on the received pressing operation input signal. Here, two push switches 11 are provided.

  The touch operation unit 12 includes an operation panel (for example, a resistive touch switch) 12a arranged such that a main surface 12a1 serving as a touch operation surface faces upward in the vehicle interior, and the touch operation performed on the touch operation surface 12a. Is detected, and a touch operation input signal reflecting the operation position is output.

  In the present embodiment, it is also unique between the two-dimensional operation coordinate system defined on the touch operation surface 12a1 of the remote operation unit 10 and the two-dimensional display coordinate system defined on the display screen of the display device 20. If the other in-plane position corresponding to one in-plane position is uniquely identifiable and there is a touch operation on the touch operation surface 22a1, the corresponding Based on the relationship, an operation input to the position coordinates on the display screen of the display device 20 corresponding to the position coordinates where the touch operation is performed is accepted. Similarly, a unique correspondence between the two-dimensional display coordinate system defined on the display screen of the display device 20 and the two-dimensional operation coordinate system defined on the touch operation surface 22a1 of the touch panel 22 is determined in advance. The other in-plane position corresponding to the one in-plane position can be uniquely specified, and the touch operation similar to the touch operation surface 22a1 of the touch panel 22 can be performed from the touch operation surface 12a1 of the remote operation unit 10 as well. Input is allowed.

  Further, as shown in FIG. 5, in the touch operation unit 12 in the present embodiment, an operation panel 12 a is fitted into the opening 12 h of a hollow housing 12 </ b> P having an opening 12 h that faces the upper side of the vehicle in the vehicle interior. The surface 12a1 is a touch operation surface (remote touch operation surface). A cylindrical peripheral wall portion 12e is provided rearward from the outer edge of the housing opening peripheral portion 12f that forms the opening 12h, and a rear end portion thereof is fixed to the circuit board 12k. The housing 12P is fixedly disposed at a predetermined position of the center console CB in the vehicle interior, and a camera 12b and a light source 12c are disposed inside.

  Similarly, as shown in FIG. 5, the light source 12c irradiates light in such a manner that the operation panel 12a is transmitted from the back surface 12a2 to the front surface 12a1. Light (irradiation light) from the light source 12c passes outside from the touch operation surface 12a1 unless there is an approaching object (such as a hand) positioned so as to cover the touch operation surface 12a1, When there is an approaching object H that is approaching the touch operation surface 12a1, it is reflected by the approaching object H and part of the light (reflected light) returns to the back surface 12a2 side, and the camera 12b. To be captured.

  The camera 12b captures the reflected object reflected from the approaching object H by the light emitted from the light source 12c, and photographs the approaching object H from the back surface 12a2 side of the operation panel 12a. It is fixed on the vehicle body side to shoot the shooting range. Further, the camera 12b here images the reflection surface of the reflection member 12r, and each is arranged so that the image (reflection image) displayed on the reflection surface includes the imaging range. When there is no reflecting member 12r, the photographing range is directly photographed by the camera 12b. Therefore, it is necessary to perform left-right reversal processing on the photographed image.

  The light source 12c of this embodiment is an infrared light source. More specifically, it is an LED located on the rear side of the operation panel 12a. On the other hand, the camera 12b of the present embodiment is an infrared camera suitable for shooting in a dark place (including an infrared filter (not shown) that shuts out visible light, and performs shooting through this). Photographing is performed in such a manner that the camera 12b captures the reflected light reflected by the approaching object H from the light (infrared rays) emitted from the light source 12c. The operation panel 12a is made of a material having translucency only with respect to the light from the light source 12c, and the inside of the housing 12P cannot be viewed from the outside.

  In the present embodiment, the camera 12b serving as an imaging unit functions as an approaching object imaging unit that captures an approaching object that approaches the surface 12a1 of the operation panel 12a. Considering that a hand is included, it can be said that it functions as a hand image photographing means for photographing an image of the hand.

  The vehicle speed sensor 30 includes a rotation detection unit such as a known rotary encoder, and is installed near the wheel mounting unit, for example, to detect the rotation of the wheel and send it to the control unit 100 as a pulse signal. In addition to converting the number of rotations of the wheels into the speed of the vehicle (vehicle speed), the control unit 100 calculates an estimated arrival time from the current position of the vehicle to a predetermined location, and calculates an average vehicle speed for each travel section of the vehicle. Or calculate. In the present embodiment, the vehicle speed sensor 30 is vehicle speed detection means (running state detection means), and the control unit 100 receives the detection result and specifies the running state of the vehicle. The means for detecting the running state of the vehicle is not limited to the vehicle speed sensor, and other means may be used. For example, as a means for detecting the running state of the vehicle, a shift position sensor is provided. When the drive position is detected, the running state (running), when the parking position is detected, the stopped state (stopped), etc. In this manner, the traveling state of the vehicle may be detected.

  The control unit 100 is configured around a well-known microcomputer including a well-known CPU, ROM, RAM, I / O (Input / Output) (not shown) and a bus line connecting these components. Various controls are performed based on a program stored in a storage unit such as the storage device 40. In addition, data can be taken in from outside such as another ECU via the LAN I / F and the in-vehicle LAN. In addition, it is possible to execute a device function of various in-vehicle electronic devices by transmitting a control signal for driving and controlling a control target of another ECU to the corresponding ECU. For example, it is possible to execute in-vehicle device functions such as a navigation function, a vehicle air conditioning function, a power window function, and an audio function.

  The drive unit 30 is a drive unit to be controlled based on operations from the touch operation unit 12 and the press operation unit 11. Such a target can be a device function of various in-vehicle electronic devices such as a navigation function. In addition to the navigation function, various drive units that perform a vehicle air conditioning function, a power window function, an audio function, and the like can be used.

  Moreover, the control part 100 performs corresponding control based on the touch operation input signal received from the touch operation parts 12a and 22. Specifically, when there is a touch operation on either of the touch operation surfaces 12a1 and 22a1, the control unit 100 specifies the position coordinates on the touch operation surfaces 12a1 and 22a1 on which the touch operation is performed, and further specifies The position coordinate on the display screen of the display device 20 corresponding to the specified position coordinate is specified, and then a control signal for executing the control content corresponding to the specified position coordinate is output. An operation screen for displaying a plurality of operation images (operation icons, etc.) 160I can be displayed on the display screen of the display device 20. When the operation screen is displayed, the operation image is displayed on the touch operation surface 22a1. When a touch operation is performed at a position corresponding to 160I, a touch operation input signal corresponding to the operation image 160I is input to the control unit 100. Since the touch operation input signal input to the control unit 100 includes operation position information reflecting the touch position on the touch operation surfaces 12a1 and 22a1, the control unit 100 that has received the input receives the operation position information. The touch position is specified based on the information, and the control content corresponding to the touch position is specified and executed.

  Note that operation image data for displaying the operation image 160I is stored in a storage unit such as the ROM of the control unit 100 or the external storage device 40, and is used for overlapping display or composite display of the operation image 160I. . On the other hand, the storage unit of the control unit 100 is also implemented by operation input to each of them (touch input to the area on the corresponding touch operation surface 12a1, 22a1) in a form associated with each operation image 160I. The control content is also stored. Thus, when the control unit 100 displays the image 160 in which the switch image 160I is superimposed on the main image (background image) 160B, the area corresponding to the display position of the switch image 160I on the touch operation surfaces 12a1 and 22a1. An operation input reception range (operation input position) is set in (operation input position setting means).

  In addition, when the hand for operating the touch operation unit 12 constituting the remote operation unit 10 faces the touch operation surface 12a1, the control unit 100 is positioned at the position on the touch operation surface 12a1 where the hand is pointing. A predetermined position indication image is displayed at the screen position of the corresponding display device 20. Specifically, based on the photographed image photographed by the camera 12b, the control unit 100 superimposes the position instruction image 160H on the background image 160B (160B1, 160B2) displayed on the display device 20, or Composite display.

  The position indication image is an image displayed at a screen position corresponding to at least the position indicated by the finger in the hand image 150H extracted from the captured image 150 by the camera 12b. Here, based on the hand image 150H binarized and extracted as shown in FIG. 6B to FIG. 9B, as the position instruction image 160H, as shown in FIG. 6 and FIG. An image in which the outline (outer shape) of the image 150H is displayed is displayed in a state where the background image 160B can be viewed in a semi-transparent state. When the hand / finger facing the operation panel 12a moves, the display position of the position instruction image (processed image) 160H displayed on the display screen of the display device 20 also moves accordingly. Note that the position instruction image 160H does not necessarily reflect the captured hand shape / finger-shaped contour, and may be an image that indicates at least the position indicated by the finger of the captured hand. The symbol image may be used. In addition, there is no problem if the hand image (or finger image) 150H photographed by the camera 12b is displayed as it is without being processed (superimposed display or composite display) as the position instruction image 160H, but the position overlapping image is displayed. In view of the fact that a part of the main image 160B that should be displayed on the screen becomes invisible, it is more desirable to perform processing (for example, translucent synthesis) that makes the operation easier.

  6 to 9 are views for explaining photographing and display of the hand (finger) H facing the surface 12a1 of the operation panel 12a. (A) of each figure has shown the state (finger state) of the hand which opposes the operation panel 12a and its surface 12a1, and (b) of each figure shows the hand (finger) of the state of (a). Is an image 150 captured by the camera 12b, and is an image captured using the entire operation panel 12a as a capturing area. However, the video 150 of (b) in this embodiment is a binarized version of the video after shooting. In (b), reference numeral 150H is an area where the approaching object H is reflected, and reference numeral 150B is an area where nothing is reflected. The region denoted by reference numeral 150B is originally a region where the operation panel 12a is reflected, but is not reflected because the operation panel 12a has translucency with respect to the light from the light source 12c. Even so, it is not strange that the background (the ceiling surface of the vehicle in the present embodiment) is reflected through the operation panel 12a, but the image cannot be captured sufficiently from the infrared reflected light. Or some of the reflected infrared light was captured, but it was made identical to the background by the binarization process. (C) of each figure is an example of the screen display in the display apparatus 20 when the image | video 150 of (b) is image | photographed. The display screen shown in FIG. 6 and FIG. 8C shows a 50-sound input screen as the main image 160B1. On the other hand, the display screen shown in FIGS. 7 and 9C displays a map screen (map operation image) displayed on the navigation device as the main image 160B2.

  By the way, in the present invention, an operation hand detecting unit (touch operation hand detecting means) 12b for detecting a hand operating the touch operation unit 12 is provided. The operation hand detection unit 12b detects a hand that is close to and faces the touch operation surface 12a1, and here, as shown in FIG. 5, a light source 12c that emits light in a predetermined wavelength band, and an operation And a camera (approaching object photographing means) 12b for photographing the front surface 12a1 side from the back surface 12a2 side of the operation panel 12a so as to include the panel 12a in the photographing range. Note that the operation panel 12a has translucency so that irradiation light from the light source 12c is transmitted from the back surface 12a2 side to the front surface 12a1 side so that the camera 12b can perform photographing. Image data taken by the camera is input to the control unit 100, and the presence of a hand is determined based on analysis processing by the image analysis unit 100a (operating hand specifying means).

  Then, the control unit 100 detects the proximity level between the hand photographed by the camera 12b and the operation panel 12a of the remote operation unit 10, and the detected proximity level exceeds the predetermined operation reception level. In this case, the display of the position instruction image is permitted, while the display of the position instruction image 160H is prohibited if the position instruction image is separated without exceeding the operation reception level. Here, the proximity level is detected as a proximity distance between the hand and the operation panel 12a. Specifically, the irradiation light is intermittently emitted from the light source 12c, the time until the reflected light of each irradiation is captured by the camera 12b is measured, and the hand and the operation panel 12a are measured from the measured time. The proximity distance between is calculated. The proximity distance is calculated every time light is emitted from the light source 12c, and the calculation result is stored as distance information in a predetermined storage area (distance information storage unit) of the external storage device 40.

  Further, the control unit 100 detects the traveling state of the vehicle, and changes the operation reception level according to the detected traveling state. FIG. 11 is a flowchart showing an example of the operation acceptance level setting change process, and is executed in such a manner that the CPU executes a predetermined program stored in the ROM of the control unit 100 or the external storage device 40. The control unit 100 functions as an operation acceptance level changing unit by executing the display process of the position instruction image.

  In S101, the control unit 100 specifies the traveling state of the vehicle. Specifically, the control unit 100 acquires the detection result of the vehicle speed sensor 30, and specifies the traveling state of the vehicle from the acquired detection result. Here, a predetermined vehicle speed threshold value is stored in the ROM of the control unit 100, and when the vehicle speed detected by the vehicle speed sensor 30 exceeds the vehicle speed threshold value, the vehicle is running at a high speed, and when the vehicle speed is not exceeded, the vehicle speed is low. Identified as a running state. In S102, when the control unit 100 determines that the vehicle is in the high speed running state, the process proceeds to S103, and when it is determined that the vehicle is in the low speed running state, the process proceeds to S104.

  In S103, the control unit 100 sets a first operation reception level that is set in advance as the operation reception level in the vehicle in the high-speed traveling state. On the other hand, in S104, the control unit 100 sets a second operation reception level that is set in advance as the operation reception level in the vehicle in the low-speed traveling state. These operation reception levels are stored in the ROM of the control unit 100, and are read and set. Here, as shown in FIG. 12, when it is determined in S102 that the vehicle is in a high-speed running state, a distance threshold (first operation acceptance) is set at a position where the proximity distance between the hand and the operation panel 12a is shorter. Level) is set, that is, the operation reception level is set at a position with a high proximity level, but if it is determined in S102 that the vehicle is in a low-speed traveling state, the proximity distance between the hand and the operation panel 12a The distance threshold (second operation reception level) is set at a position where is longer, that is, the operation reception level is set at a position where the proximity level is low. The set operation reception level is stored in a predetermined storage area (operation reception level storage unit) of the external storage device 40.

  Although this process is also ended by the end of S103 or S104, this process is performed in a predetermined cycle even after the end, and the operation reception level stored in the external storage device 40 is updated as needed.

  In addition, as a vehicle speed threshold value, it can set between 0 km / h-30 km / h of a vehicle. In addition, the vehicle speed threshold is set between 0 km / h and less than 10 km / h, the first operation acceptance level is set in a high-speed driving state exceeding the vehicle speed threshold, and in a slow-running state where the vehicle speed threshold is not lower than the vehicle speed threshold. A second operation acceptance level can be set. Also, the vehicle speed threshold is set to 0 km / h, the first operation acceptance level is set when the vehicle is running (running), and the second operation acceptance level is set when the vehicle is stopped (stopped). May be.

  FIG. 10 is a flowchart illustrating an example of the position indication image display process performed based on the operation reception level set in FIG. 11, and a predetermined program stored in the ROM of the control unit 100 or the external storage device 40. Is executed by the CPU. The control unit 100 functions as a position instruction image display control unit by executing the position instruction image display process.

  In S1, the control unit 100 determines whether an image of the operator's hand has been acquired based on the captured image captured by the camera 12b. The camera 12b always shoots an approaching object (for example, an operator's hand such as a driver) H that approaches the touch operation surface (front surface) 12a1 side from the back surface 12a2 side of the operation panel 12a via the operation panel 12a. The captured image is always input to the image processing unit 18a of the control unit 100. When the approaching object H enters the position facing the touch operation surface 12a1, the captured image 150 including the approaching object H is naturally input to the image processing unit 18a. The input captured image 150 is analyzed by a known image analysis method in the image analysis unit 100a, and the approaching object image 150H is extracted based on the difference in color, the difference in luminance, and the like. Then, it is determined by known pattern matching or the like whether or not the extracted approaching object image 150H is an image of a human hand. The determination result is output to the control unit 100. If it is determined that the hand image has been recognized, the process proceeds to S2, and if not determined, the process ends.

  In the present embodiment, the light source 12c is disposed, and the camera 12b performs imaging in a manner that captures the reflected light of the light source 12c. Therefore, the reflected light intensity is reflected in the gradation of the color appearing in the captured image 150, and the higher the reflected light intensity, the higher the gradation level. That is, since the captured video 150 captured by the camera 12b of the present embodiment is a multi-gradation captured image (monochrome captured image in the present embodiment), the image processing unit 18a converts the captured image 150 into a predetermined gradation. The gradation level of each pixel is binarized using the threshold value, and the area exceeding the gradation threshold value is extracted as the approaching object image 150H as shown in FIGS. Further, in the image processing unit 18a, the shape of the approaching object image 150H and the hand shape stored in the storage unit of the control unit 100 are specified in order to identify the image of the human hand from the extracted approaching object image 150H. Compared with patterns, the approaching object image 150H that matches those patterns is recognized as a hand image (hand image recognition means: operating hand specifying means).

  In S <b> 2, the control unit 100 acquires distance information reflecting the proximity level between the hand photographed by the camera 12 b and the operation panel 12 a of the remote operation unit 10. Here, as described above, the measurement result of the time from when the light is emitted from the light source 12c for photographing at S1 until the hand image is captured as the reflected light is obtained, and from the measured time The proximity distance between the hand and the operation panel 12a is calculated.

  In subsequent S3, based on the distance information acquired in S2, the control unit 100 sets the proximity level between the hand photographed by the camera 12b and the operation panel 12a of the remote operation unit 10 to a predetermined operation reception level. It is determined whether or not they are close to each other. Since the operation acceptance level is stored in the predetermined storage unit of the external storage device 40, it is read and used. Here, the distance between the hand photographed by the camera 12b and the operation panel 12a of the remote operation unit 10 obtained based on the distance information acquired in S2 is based on the distance threshold value that forms the read operation reception level. If the distance is shorter than the distance threshold, the process proceeds to S4. If the distance is not shorter than the distance threshold, the process proceeds to S7.

  In S4, the control unit 100 sets a display permission mode for permitting display of the position instruction image 160H as the display mode, and the process proceeds to S5. The set display mode is stored in a predetermined storage area (display mode storage unit) provided in the storage unit of the control unit 100. In S4, the display permission mode is stored in the storage area.

  In S5, the control unit 100 specifies the positional relationship between the display screen of the display device 15 and the photographed hand. That is, the position on the display screen where the photographed hand image H faces is specified. In the present embodiment, the operation panel image area where the touch operation surface 12a is located is specified on the captured image captured by the camera 12b, and the operation coordinate system of the touch operation surface 12a is set on the operation panel image area. Then, the position of the captured hand image H is specified on the set operation coordinate system. Then, in the display coordinate system defined on the display screen of the display device 15, a position corresponding to the position of the hand image H specified on the operation coordinate system is specified. In the present embodiment, the captured image (binarized image) 150 shown in FIGS. 6 to 9B is an operation panel image area obtained by capturing the entire touch operation surface 12a1.

  Further, in S6, as shown in FIG. 6 and FIG. 7C, the position indicating image is displayed at the position corresponding to the hand image H specified on the operation panel image area on the display screen of the display device 15. 160H is displayed (position indication image display means).

  On the other hand, in S7, the display mode is set to a display prohibition mode for prohibiting display of the position indicating image. As a result, the display of the position indication image performed in S5 and S6 is not executed, and the position indication image 160H is displayed on the display screen of the display device 15 as shown in FIG. 8C and FIG. 9C, for example. Do not show. The set display prohibition mode is stored in a predetermined storage area (display mode storage unit) provided in the storage unit of the control unit 100.

  This process is ended by the end of S6 and S7. Note that this process is repeatedly performed at a predetermined cycle after the end, and when the hand facing the operation panel 12a moves, the display position of the position instruction image 160H displayed on the display screen of the display device 15 also moves accordingly. To do. However, when the proximity level between the hand facing the operation panel 12a and the operation panel 12a of the remote operation unit 10 exceeds the predetermined operation reception level, the position instruction image 160H is displayed. Disappears.

  By this processing, the position instruction image 160H is difficult to be displayed when the vehicle is in the high speed running state, and is easily displayed when the vehicle is in the low speed running state. Therefore, when the vehicle is in the high speed running state, the position instruction image 160H is difficult to be displayed, so that the operation by the driver or the like to the remote control unit 10 can be suppressed, and the vehicle is put in the low speed running state. In some cases, since the position instruction image 160H is displayed immediately, the remote operation unit 10 can be smoothly operated.

  Although one embodiment of the present invention has been described above, this is merely an example, and the present invention is not limited to this, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible. Hereinafter, an embodiment different from the above embodiment will be described. In addition, about a common structure, description is abbreviate | omitted by using the same code | symbol.

  A second embodiment will be described.

  In the case of the first embodiment, the position instruction image 160H is less likely to be displayed when the vehicle is in the high speed running state, and is easier to be displayed when the vehicle is in the low speed running state. The remote operation unit 10 can be smoothly operated when the vehicle is in the high speed running state, and the position indication image 160H can be prevented from being displayed wastefully when the vehicle is in the low speed running state. It may be. More specifically, this can be realized by performing an operation reception level setting change process as shown in FIG.

  A third embodiment will be described.

  In the case of the above-described embodiment, when the proximity level between the hand facing the operation panel 12a and the operation panel 12a of the remote operation unit 10 is located near the operation reception level, the position instruction image is displayed or disappears. May repeat. In order to omit such useless processing, the direction of movement of the hand photographed by the camera 12b in the approach / separation direction to the operation panel 12a is detected, and the operation reception level is changed according to the detected direction of movement. Can be configured to Specifically, the configuration is such that the operation acceptance level is set higher when the hand photographed by the camera 12b moves away from the operation panel 12a than when the hand moves closer to the operation panel 12a. To do. As a result, it is difficult to display the position instruction image on the assumption that there is no intention to operate when leaving the operation panel 12a. For this reason, when the hand photographed by the camera 12b is located near the operation acceptance level, it is not displayed when the hand moves away from the operation panel 12a. FIG. 13 shows an example of the operation reception level setting process in the second embodiment.

  First, when the control unit 100 specifies the traveling state of the vehicle at S120, and when the control unit 100 determines at S121 that the vehicle is in the low-speed traveling state that does not exceed a predetermined reference vehicle speed level. The process proceeds to S122, and if it is determined that the vehicle is in the high speed traveling state exceeding the reference vehicle speed level, the process proceeds to S126. S120 and S121 are the same processes as S1 and S2 in FIG.

  In S122, the control unit 100 specifies the moving direction in the approach / separation direction A toward the operation panel 12a of the hand photographed by the camera 12b. Specifically, while waiting for the execution of a new shooting, the proximity distance between the hand and the operation panel 12a at the time of shooting is calculated in the same manner as in the above-described embodiment. The distance information at the time of the previous photographing stored in the predetermined storage area (distance information storage unit) of the external storage device 40 is read, the proximity distance at the time of the previous photographing is obtained, and the difference between the hand and the operation panel 12a is obtained. By determining whether the distance is reduced or enlarged, the moving direction of the hand taken by the camera 12b in the approach / separation direction to the operation panel 12a is specified.

  In S123, if the movement of the hand taken by the camera 12b in the direction away from the operation panel 12a is not specified, the process proceeds to S124, in which the control unit 100 is set to a predetermined first as the operation reception level. Set the operation acceptance level for. On the other hand, when the movement of the hand taken by the camera 12b in the direction away from the operation panel 12a is specified in S123, the process proceeds to S125, and the control unit 100 is predetermined as the operation reception level. Set the third operation acceptance level.

  On the other hand, in S126, as in S122, the moving direction in the approach / separation direction A toward the operation panel 12a of the hand photographed by the camera 12b is specified. In subsequent S127, if the movement of the hand taken by the camera 12b in the direction away from the operation panel 12a is not specified, the process proceeds to S128, and the control unit 100 determines a second predetermined value as the operation reception level. Set the operation acceptance level for. On the other hand, when the movement of the hand taken by the camera 12b in the approaching direction to the operation panel 12a is specified in S127, the process proceeds to S129, and the control unit 100 is preset as the operation reception level. Set the fourth operation acceptance level.

  These operation reception levels are stored in the ROM of the control unit 100, and are read and set. Here, each operation reception level shown in FIG. 15 is set. That is, when it is determined that the vehicle is in a predetermined high-speed traveling state (S121: No) and the hand facing the operation panel 12a is not separated from the operation panel 12a (S123: No), the hand and the operation panel 12a The distance threshold is set at a predetermined position where the proximity distance between the vehicle and the vehicle is the shortest, that is, the first operation acceptance level is set at the position with the highest proximity level, while the vehicle is traveling at a predetermined high speed. When it is determined that the state is in the state (S121: No) and the hand facing the operation panel 12a moves away from the operation panel 12a (S123: Yes), the proximity distance between the hand and the operation panel 12a is as described above. The distance threshold is set at a predetermined position that is longer than the distance threshold at the first operation reception level, that is, at the position where the proximity level is lower than the first operation reception level. Of the operation reception level is set. As a result, when it is determined that the vehicle is in the high speed running state, the position instruction image 160H is difficult to be displayed when the hand moves away from the operation panel 12a, and when the hand does not move away from the operation panel 12a. It becomes easy to be displayed.

  If it is determined that the vehicle is in a predetermined low speed traveling state (S121: Yes) and the hand facing the operation panel 12a is not separated from the operation panel 12a (S127: No), the hand and the operation panel 12a The distance threshold is set at a predetermined position where the proximity distance between the first operation acceptance level and the first operation acceptance level is the longest, that is, the proximity level is lower than the first operation acceptance level. When the third operation acceptance level is set, it is determined that the vehicle is in a predetermined low-speed traveling state (S121: Yes), and the hand facing the operation panel 12a moves away from the operation panel 12a ( S127: Yes), a distance threshold is set at a predetermined position where the proximity distance between the hand and the operation panel 12a is the longest, that is, at the position where the proximity level is the lowest. Fourth operation reception level is set. Thereby, when it is determined that the vehicle is in the low-speed traveling state, the position instruction image 160H is difficult to be displayed when the hand moves away from the operation panel 12a, and when the hand does not move away from the operation panel 12a. It becomes easy to be displayed.

  In the operation reception level shown in FIG. 15, the third operation reception level may be set to a proximity level lower than the second operation reception level, and further, the proximity lower than the fourth operation reception level. It may be set to a level.

  A fourth embodiment will be described.

  In the case of the above-described embodiment, the distance between the hand photographed by the camera 12b and the operation panel 12a is calculated based on the reflection response speed of the light source 12c that is intermittently lit, but other methods are employed. May be. For example, as shown in FIG. 16, the camera 60 (configured) connected to the control unit 100 is arranged so that the distance d between the touch operation surface 12a1 and the hand facing the touch operation surface 12a1 is reflected. The distance d can be calculated from the captured image. Here, the space above the touch operation surface 12a1 can be provided, for example, in the center console CB or the like so as to photograph from the side.

  A fifth embodiment will be described.

  In the case of the above-described embodiment, a direct distance between the hand photographed by the camera 12b and the operation panel 12a is calculated, and a threshold value that determines an operation reception level with respect to the distance is provided. The value may reflect the distance between the hand photographed by the camera 12b and the operation panel 12a. In this case, a value fixedly set for the detected value is used as the threshold value (detected value threshold value) that forms the operation acceptance level. And even if it is a case where the distance between the hand image | photographed with the camera 12b and the operation panel 12a is the same, a detection condition is changed so that the said detected value itself may increase or decrease. Thereby, since the calculation method for converting the detected value into the distance is changed, the detected value threshold value is also changed after the distance conversion, and as a result, the operation reception level is changed.

  For example, in the case of a configuration in which the distance between the hand photographed by the camera 12b and the operation panel 12a is specified from the luminance of each pixel of the photographed image photographed by the camera 12b, the light emission intensity of the light source 12c can be increased. Since the received light intensity of the reflected light also increases, even if a hand at the same position is photographed, the average level of luminance of each pixel in the photographed image increases. Therefore, if a threshold value that defines the operation acceptance level with respect to the luminance is determined, the value obtained by converting the luminance threshold value that constitutes the operation acceptance level into a distance is changed by increasing or decreasing the light emission intensity of the light source 12c. Thereby, the operation level can be easily changed only by adjusting the light emission intensity of the light source 12c. That is, if it is desired to increase the operation acceptance level, the light emission intensity of the light source 12c may be increased, and if it is desired to reduce the operation acceptance level, the light emission intensity of the light source 12c may be decreased. Here, the threshold value determined for the luminance is a value used as a reference value in binarization distribution in the binarization processing of the captured image.

  Another embodiment will be described.

  In the above embodiment, the touch panel 22 and other switches 21 provided in the display device 20 are not essential components of the present invention. For this reason, the display device 20 according to the present invention is not limited to the one arranged in the center console CB as shown in FIGS. 2 and 3, and is installed above the lower edge of the windshield FG, for example. Also good. Specifically, a head-up display (HUD) for displaying the above-described images and data on the windshield FG of the vehicle, a meter display device located behind the steering wheel 6 on the vehicle front side, and the like can also be exemplified. .

  In the above embodiment, the remote operation unit 10 and the display device 20 are provided with a resistive touch panel as a touch operation unit, but other types of touch panels may be used. For example, an operation panel 12a that detects the position of a touch operation by performing image processing on a photographed image photographed by photographing means such as the camera 12b may be employed instead of the touch panel. Specifically, the operation panel 12a is a translucent panel whose surface 12a1 forms a touch operation surface, and a wavelength predetermined for an approaching object that approaches the operation panel 12a from the touch operation surface 12a1 side. A light source 12c for irradiating the band light through the operation panel 12a is provided. Then, the camera 12b serving as a photographing unit captures the approaching object from the back surface 12a2 side of the operation panel 12a1 in such a manner that at least the light emitted from the light source 12c is reflected by the approaching object. Means. Further, as shown in FIG. 17, the control unit 100 specifies a light reflection area 171H that specifies a light reflection area 171H whose reflected light intensity exceeds a predetermined threshold intensity on an image 170H photographed by the camera 12b. In addition to functioning as a means, the position of the specified light reflection region 171H is specified, and it is also configured to function as an input receiving means for receiving a touch input corresponding to the position. Note that the image 170H is not subjected to the binarization process like the image 150 described above, and is an image as it is taken, and has various luminance level differences in the entire area. Since the region where the hand is in contact with the operation panel 12a has a significantly higher reflected light intensity than other regions, it is possible to determine whether or not the operation panel 12a has been operated, and further identify the operated position. can do.

  According to this configuration, when a light reflection area 171H exceeding a predetermined threshold intensity is specified in a captured image of the camera 12b, it is determined that a touch operation input has been made in the specified area, and the input is accepted. That is, the captured image of the camera 12b is not only used for detection of the operating hand and display of the position instruction image, as in the above-described embodiment, but also the presence / absence determination of the light reflection region 171H and the light reflection. This configuration is also used for specifying the position (operation position) of the area 171H. In this case, it is also possible to accept a touch operation input to the light reflection region 171H only when the area of the specified light reflection region 171H exceeds a predetermined threshold area.

  Moreover, in the said embodiment, although the press operation part 11 and the touch operation part 12 are made into the operation part which can be operated from a driver's seat and a passenger seat, it can also be set to the operation part which can be operated from another seat. However, an operation unit that can be operated only from one of the driver seat and the passenger seat may be used.

  Moreover, the control part 100 in the said embodiment can be combined with the control part of a vehicle-mounted navigation apparatus, for example. FIG. 18 is a block diagram showing an example of the configuration of the in-vehicle navigation device. As shown in FIG. 18, the navigation device 50 includes a position detector 57 that detects the current position of the vehicle, an operation unit 51 for inputting various instructions from an operator such as a driver, map data, and various types of data. Outputs a map data input device 55 for inputting map data from an external recording medium in which information is recorded, a display device 52 for performing various displays such as a map display screen and a TV (Television) screen, and various guide voices. A voice input / output device 53 for inputting voice of an operator such as a driver and a hard disk storage device (external storage) for storing various information such as map data and vehicle information necessary for the navigation function Device) 54, a vehicle I / F (Interface) unit 56 for exchanging vehicle information, and a control unit 59 connected to these units 51-57. The position detector 57 is a known device including a GPS receiver, a gyroscope, a distance sensor, and a geomagnetic sensor.

  The control unit 59 is configured around a well-known microcomputer including a well-known CPU, ROM, RAM, I / O (Input / Output) (not shown) and a bus line connecting these components. By executing the navigation program stored in the storage unit, based on each detection signal from the position detector 57 and various data stored in the storage device 54, calculation of the current position, map display processing, destination setting, route Execute well-known navigation functions such as calculation and route guidance processing.

  When the CPU executes a predetermined program stored in a storage unit such as a ROM, the control unit 59 performs the above-described position instruction image display processing (FIG. 10) and operation reception level setting change processing (FIGS. 11, 13, and 13). 14) is carried out. That is, the control unit 59 functions in the same manner as the control unit 100 of the already described embodiment (FIG. 1). Further, the operation unit 51 and the display device 52 also function in the same manner as in the above-described embodiment (FIG. 1). That is, the vehicle operation input device of the present invention is applicable as an operation input device of the navigation device 50 as an example. Therefore, the operation input device 1 of FIG. 1 can also be applied as an operation input device of a navigation device.

  In the above-described embodiment, the processed image (real finger image) 160H in which the contour shape of the photographed finger is directly reflected on the camera 12b is displayed as the position instruction image 160H. An image completely different from the finger shape may be displayed, such as a fingertip position image (pointer or the like: see FIG. 20) 160H2 indicating Q (that is, the pointed position of the photographed finger). If highlighting is to be performed, only the fingertip region including the fingertip Q (for example, up to the first joint of the finger or an area within a predetermined radius centered on the fingertip position Q) may be displayed with emphasis. In this case, it is specified which position on the display screen the fingertip Q of the photographed finger faces, and a predetermined position indication image such as a pointer is displayed at the specified screen position. Further, as the position instruction image 160H, a pseudo finger image (here, a bar-shaped image: see FIG. 19) 160H1 or the like that simply shows the photographed finger length direction F and the fingertip Q may be displayed.
