Description

  The present invention relates to a vehicle opening / closing device that opens and closes an opening provided in a vehicle, such as a door, a power slide door device, a window, and a power window device provided in the vehicle, and more specifically, a vehicle that controls opening and closing of the opening. The present invention relates to an open / close control device.

  Some vehicles include an automatic door opening and closing device that opens and closes a door for getting on and off by a switch operation. For example, some vehicles provided with a slide door include a power slide door device that can move the slide door in an opening direction and a closing direction by an actuator such as a drive motor.

  In this power slide door device, the lock state is released by the switch operation and the drive motor is operated to move the slide door to the fully open position or the fully closed position. Thereby, in the vehicle provided with the power slide door device, it is easy to close and lock the slide door when getting off the vehicle.

  On the other hand, in a parked vehicle, the environment in the passenger compartment changes in response to environmental conditions such as weather around the vehicle. For example, when a vehicle is parked under hot weather in midsummer, etc., if the passenger compartment is sealed, the temperature inside the passenger compartment may become extremely high. If there are animals or animals, it will cause serious illness.

  From here, in Patent Document 1, when a detection target is detected in the passenger compartment when a person or animal is detected and the door is locked, the passenger is notified that the detection target is in the passenger compartment. It proposes that the detection target in the passenger compartment can be protected.

  By the way, if it is easy to close and lock the door when getting off, the driver may forget that other occupants and animals remain in the passenger compartment and lock the door to leave the vehicle. However, if the occupant remaining in the sealed vehicle compartment is an adult or a relatively old child (children, etc.), he / she can release the door lock himself and get out of the vehicle.

However, if the occupant remaining in the vehicle interior is an infant, it is difficult to evacuate outside the vehicle, and if the environment inside the vehicle interior changes, there is a high possibility that physical condition will deteriorate.

  The present invention has been made in view of the above-mentioned facts, and forgets that an infant is present in a sealed vehicle interior, and can prevent a passenger such as a driving car from leaving a parked vehicle. An object is to provide a control device.

  In order to achieve the above object, the present invention provides an opening / closing body provided in an opening communicating with the outside of a vehicle interior and movable toward a position for closing and opening the opening, and whether the vehicle is in a parked state. Parking detection means for detecting whether or not, occupant detection means for detecting an occupant in the vehicle interior, determination means for determining whether the occupant detected by the occupant detection means is an infant, and the opening and closing body When the vehicle is detected to be parked by the parking detection means when moving in the closing direction of the opening and the determination means determines that an infant is boarded, at least the opening / closing body fully closes the opening. And prohibiting means for prohibiting.

  According to this invention, opening and closing of windows, entrances, and the like can be opened and closed by moving the opening and closing body in the opening direction and the closing direction. When the opening / closing body is moved and the opening is closed, the vehicle is parked by the parking detection means, and the passenger in the vehicle compartment detected by the occupant detection means is determined to be an infant by the determination means. The prohibiting means prohibits at least the opening from being fully closed.

  As a result, it is possible to prevent the passenger compartment from being hermetically sealed in the state where the infant is left in the passenger compartment.

  In addition, as an infant determined by the determination means, a child of an age that seems to be difficult to open and close the door and the window glass with at least his own power can be applied. In addition, the determination means may determine from the physique based on the average body type (average physique) such as the average height and the average sitting height of the corresponding age, and it is determined by whether or not a child seat is used. There may be.

  According to a second aspect of the present invention, there is provided drive means for moving the opening / closing body in the opening direction and closing direction of the opening, request detecting means for detecting an opening request and a closing request for the opening by the opening / closing body, and the request detection. Opening and closing control means for opening and closing the opening by operating the driving means based on a detection result of the means, and when the request detection means detects a closing request of the opening and closing body, the prohibiting means, The operation of the opening / closing control means is controlled based on the detection result of the parking detection means and the determination result of the determination means.

  According to this invention, the opening / closing body is moved in the closing direction and the opening direction of the opening by the operation of the moving means, and the opening / closing is performed. The opening / closing control means controls the moving means so that the opening / closing body is moved in the opening direction or the closing direction when the opening request or the closing request is detected.

  Here, when at least the fully closed state of the opening is prohibited by the prohibiting means, the opening / closing control means controls the moving means so that the opening is not at least fully closed.

  Thus, even when the opening is automatically opened and closed based on the opening / closing request, it is possible to prevent the opening from being closed while the infant is on board and the vehicle interior from being sealed.

  In the present invention, the prohibiting means may control the opening / closing control means so that the movement of the opening / closing body in the closing direction is prohibited. Further, the opening may be a passenger entrance / exit, the opening / closing body may be a door, and the door may be a sliding door.

  For example, when a swing door such as a front hinge door that opens and closes the entrance as an opening / closing body is applied, when the door is closed by manual operation, it is determined that the infant is in a parked state, thereby Because it is prohibited to become, it becomes a half door state.

  In addition, when a sliding door that is moved in the opening / closing direction by the moving means is applied, when the request detecting means detects a sliding door closing request, it is determined that the infant is in the parked state, and the slide The door is prevented from moving in the closing direction.

  Thereby, it can prevent reliably that a vehicle is parked in the state which left the infant in the vehicle interior. When applying a sliding door or hinge door as an opening, it is prohibited to move the sliding door or swing door in the fully closed state or the sliding door in the closing direction when it is determined that only an infant is on board. It is preferable that the door is closed unnecessarily.

  As described above, according to the present invention, when it is determined that there is an infant as an occupant in the passenger compartment, the opening is prohibited from being closed by the opening / closing body, and the passenger compartment remains in a state where the infant remains. Since it is not sealed, it is possible to prevent the infant from being parked while remaining in the passenger compartment.

  Further, in the present invention, the closing operation of the door such as the sliding door is prohibited in the state where only the infant remains in the passenger compartment, and the fully open state or the half-door state is established, so that the infant remains in the passenger compartment. It is possible to obtain an excellent effect that it is possible to surely prevent the vehicle from being locked without being noticed and parked.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 shows a schematic configuration of the vehicle 10 according to the present embodiment. This vehicle 10 is provided with a sliding door 12 (only one is shown in FIG. 2) as an opening / closing body on each of a driver seat side and a passenger seat side. Is opened and closed. That is, in the vehicle 10, the entrance 16 is opened by opening the slide door 12, and it is possible to get on and off.

  The vehicle 10 is provided with a power slide door device 20. The vehicle 10 can open and close the slide door 12 by a switch operation. In the power sliding door device 20, the basic structure of the opening / closing mechanism of the sliding door 12 on the driver's seat side and the passenger seat side is the same. In the following, one sheet is used without distinguishing between the driver seat side and the passenger seat side. The opening and closing of the sliding door 12 will be described as an example.

  As shown in FIG. 1, the power sliding door device 20 is provided with an opening / closing control device 22 that controls opening / closing of the sliding door 12. The opening / closing control device 22 includes an automatic door control computer (hereinafter referred to as an automatic door ECU 24) as an opening / closing control means. The automatic door ECU 24 has a general configuration including a microcomputer in which a CPU, a ROM, a RAM, and the like are connected by a bus, an input / output interface, and various drive circuits (all not shown).

  A main switch 26 is connected to the automatic door ECU 24 and power for operation is always supplied from a battery (not shown) of the vehicle 10. Thus, in the automatic door ECU 24, the main switch 26 is turned on, so that the slide door 12 can be opened and closed regardless of whether the ignition switch of the vehicle 10 is on or off.

  The automatic door ECU 24 includes an ignition switch 28, a vehicle speed sensor 30 for detecting the traveling speed of the vehicle 10, a brake switch 32 for detecting the operation of the brake pedal, a parking brake switch 34 for detecting the operation of the parking brake, and a shift position. A shift position sensor 36 to be detected is connected. The ignition switch 28 outputs a signal indicating whether or not the ignition key is inserted together with turning on / off the ignition, whereby the automatic door ECU 24 causes the ignition switch 28, the vehicle speed sensor 30, and the brake switch 32 to be output. From the detection state of the parking brake switch 34 and the shift position sensor 36, it is determined whether or not the vehicle 10 is stopped or parked. Further, the automatic door ECU 24 is configured to allow the sliding door 12 to be opened and closed when it is determined that the vehicle 10 is stopped or parked.

  That is, the automatic door ECU 24 enables the sliding door 12 to be opened and closed (particularly opening operation) when the main switch 26 is turned on and the vehicle 10 is in a stopped state (running stop or parking state). A known general configuration can be applied to the basic configuration of the opening / closing control of the slide door 12.

  As shown in FIG. 2, the slide door 12 is provided with a drive unit 38, a full lock unit 40, and a lock release unit 42 as moving means. The drive unit 38 moves the sliding door 12 in the opening direction and the closing direction, and the full lock unit 40 is moved to a predetermined position in the closing direction by the driving unit 38 or manual operation. And the slide door 12 is moved to the fully closed position, and the slide door 12 is brought into a locked state.

  The slide door 12 is locked and held in a fully closed position and a fully open position by a lock mechanism (not shown), and the lock release unit 42 operates when the slide door 12 is opened and closed. Then, the locked state of the slide door 12 is released. Thus, the slide door 12 can be moved in the opening direction or the closing direction by the drive unit 38 or manual operation.

  As shown in FIG. 1, the drive unit 38, the full lock unit 40 and the lock release unit 42 are connected to the automatic door ECU 24. In addition, the drive unit 38, the full lock unit 40, and the lock release unit 42 are provided with, for example, a motor (hereinafter, referred to as a drive motor 44, a full lock motor 46, and a lock release motor 48) as an actuator. The automatic door ECU 24 opens and closes (opens and closes) the slide door 12 by controlling driving of the drive motor 44, the full lock motor 46 and the lock release motor 48.

  That is, when the opening request is detected when the slide door 12 is fully closed, the automatic door ECU 24 drives the lock release motor 48 to release the lock state of the slide door 12 and operates the drive motor 44 to slide. The door 12 is moved in the opening direction. Thereby, when the slide door 12 is moved to the fully open position, it is locked in the fully open state by a lock mechanism (not shown).

  Further, when the automatic door ECU 24 detects the close request in the fully open state of the slide door 12, the automatic door ECU 24 drives the lock release motor 48 to release the lock state of the slide door 12, and operates the drive motor 44 to operate the slide door. 12 is moved in the closing direction. Further, when the slide door 12 moved in the closing direction reaches a predetermined position, the automatic door ECU 24 stops the drive motor 44 and drives the full lock motor 46 to move the slide door 12 to the fully closed position. The locked state is held by a lock mechanism (not shown).

  The opening / closing control device 22 is provided with, for example, a pinch detection sensor (hereinafter referred to as a touch sensor 50) of the slide door 12 using a touch sensor or the like, and the touch sensor 50 is connected to the automatic door ECU 24. . The drive unit 38 outputs a pulse corresponding to the rotation of the drive motor 44 to the automatic door ECU 24. The automatic door ECU 24 counts the pulses output from the drive unit 38 to move the slide door 12. The position and the moving speed can be detected.

  The automatic door ECU 24 moves the slide door 12 in the opening direction by driving the drive motor 44 in the reverse direction when the pinching is detected from the speed of the slide door 12 or the detection result of the touch sensor 50 during the closing operation of the slide door 12. It is designed to prevent pinching.

  In the present embodiment, the sliding door 12 is opened and closed using the drive unit 38, the full lock unit 40, and the lock release unit 42, and pinching detection is performed from pulses according to the rotation of the touch sensor 50 and the drive motor 44. Although it is assumed that the opening / closing mechanism, the driving mechanism, the pinching prevention mechanism, and the like of the slide door 12 are not limited thereto, any configuration can be applied.

  On the other hand, the open / close control device 22 is provided with a door switch 52 and handle switches 54 and 56 as request detecting means for detecting opening and closing of the slide door 12, and these are connected to the automatic door ECU 24. The door switch 52 is provided, for example, on an instrument panel (not shown), and one of the handle switches 54, 56 (for example, the handle switch 54) is provided near the door handle on the outside of the slide door 12 or near the door handle. (For example, a handle switch 56) is provided inside the slide door 12 or in the vicinity of the door handle.

  The automatic door ECU 24 determines that an opening request for the sliding door 12 is input by operating either the door switch 52 or the handle switches 54 and 56 when the sliding door 12 is fully closed. I do. Further, when it is detected that either the door switch 52 or the handle switches 54 and 56 is operated in the fully opened state of the slide door 12, it is determined that the request for closing the slide door 12 is input, and the slide door 12 Close operation is performed.

  In addition, the power slide door device 20 includes a remote control switch 58 as a request detection unit and a reception unit 60 that receives a transmission signal from the remote control switch 58, and the reception unit 60 is connected to the automatic door ECU 24.

  As long as the remote control switch 58 can individually input the opening / closing requests of the sliding doors 12 on the driver's seat side and the passenger seat side, any configuration can be applied, and the switch operation for requesting the opening / closing of the sliding door 12 is performed. And a signal corresponding to the switch operation together with the identification ID and the like. When receiving the signal transmitted from the remote control switch 58, the receiving unit 60 outputs an operation signal for the slide door 12 based on the received signal to the automatic door ECU 24.

  When the operation signal is input from the receiving unit 60, the automatic door ECU 24 opens the slide door 12 based on the input operation signal, as in the case where the door switch 52 or the handle switches 54 and 56 are operated. Execute the closing operation. Thereby, the opening / closing operation | movement of the sliding door 12 is possible, without touching the position away from the vehicle 10, or the handle switch 54 directly.

  The opening / closing control device 22 is provided with a speaker 62, and this speaker 62 is connected to the automatic door ECU 24. In the automatic door ECU 24, when the slide door 12 is moved (opening / closing operation), an alarm or the like is issued from the speaker 62 to notify the passenger of the movement of the slide door 12 and to call attention.

  In the power slide door device 20, when the slide door 12 is locked by a key operation (not shown), the power switch door device 20 is in the same state as when the main switch 26 is turned off, and the opening operation of the slide door 12 is prohibited. ing. As a result, when the slide door 12 is locked, the opening operation of the slide door 12 by the handle switch 54 and the remote control switch 58 is prohibited from outside the vehicle. The sliding door 12 may be locked / released by a switch operation provided on the remote control switch 58.

  By the way, as shown in FIG. 1, the power slide door device 20 is provided with an imaging device 64 as an occupant detection means, and the imaging device 46 can monitor the inside of the passenger compartment 14. The imaging device 64 includes a camera 66 serving as an imaging unit, and an image processing unit 68 that controls image capturing by the camera 66 and performs image processing on an image captured by the camera 66.

  As shown in FIG. 2, the camera 66 is disposed, for example, in the upper part on the front side of the passenger compartment 14 and can take images on the driver seat, the passenger seat, and the rear seat. Such a camera 66 may be a fixed type whose direction is fixed as long as the inside of the passenger compartment 14 can be monitored. The camera 66 can be set in a predetermined range by swinging the direction up and down and left and right. A rotating type capable of taking an image may be used.

  The image processing unit 68 captures the interior of the passenger compartment 14 with the camera 66 at a predetermined timing, and reads image data of the captured image (hereinafter referred to as a captured image) from the camera 66. In addition, the image processing unit 68 performs predetermined image processing on the image captured by the camera 66, thereby extracting the contour of the object to be photographed such as a seat (driver's seat, front passenger seat, rear seat) or an occupant, for example. Thus, image data indicating the contour is generated.

  The imaging device 64 is provided with a determination processing unit 70 as occupant detection means and determination means. Image data (contour image data) generated by the image processing unit 68 is input to the determination processing unit 70. The determination processing unit 70 uses the input image data to calculate the driver seat and the passenger seat. Alternatively, it is determined whether there is a passenger in the rear seat. Further, when the determination processing unit 70 determines that there is an occupant, the determination processing unit 70 determines whether the occupant is an infant Cc.

  As such an image processing unit 68, an arbitrary configuration for extracting the contour of a captured image can be applied. Further, in the determination processing unit 70, for example, a template corresponding to the contour of the occupant is stored, and the presence or absence of the occupant is determined by comparing the template with the contour image indicated by the image data input from the image processing unit 68. . Whether or not the occupant is an infant Cc is determined, for example, when an occupant under the age of 6 is determined as an infant Cc, based on a standard body shape such as an average height or an average sitting height of the infant Cc of this age. A template based on a standard body shape is stored, and it is determined that the occupant is an infant Cc when the size of the contour of the occupant indicated by the image data is close to the template size or smaller than the template.

  That is, the determination processing unit 70 sets an occupant who is difficult to open / close the slide door 12 or the window glass 12A (see FIG. 2) as an infant Cc under 6 years old, and determines the infant Cc. It is targeted. At this time, on the basis of the average physique of a 6-year-old child, by judging whether or not an occupant with a physique equivalent to this standard or a physique smaller than the standard is on board, at least a determination omission will not occur Yes.

  Further, as shown in FIG. 2, when an infant Cc under 6 years old gets on, a child seat 72 is basically used. From this, it is detected whether or not the child seat 72 is attached, and when the child seat 72 is attached, it is determined whether or not an occupant is seated on the child seat 72. At this time, if an occupant is seated on the child seat 72, it may be determined that the infant Cc to be determined is on board.

  In the imaging device 64, an image processing unit 68 and a determination processing unit 70 are connected to the automatic door ECU 24. As a result, the imaging device 64 captures an image based on a request from the automatic door ECU 24 and outputs a determination result as to whether the infant Cc is on the vehicle to the automatic door ECU 24.

  On the other hand, when the vehicle 10 is parked, the ignition key is removed from the ignition switch 28, the parking brake is applied, and the shift position is set to the parking (P) position. From this point, in the opening / closing control device 22, the parking brake switch 34 and the shift position sensor 36 or the ignition switch 28, the parking switch 34 and the shift position sensor 36 are used as parking detection means, and the automatic door ECU 24 is operated by the ignition switch 28, the parking brake switch. 34 or from the detection result of the shift position sensor 36, it is determined whether or not the vehicle 10 is parked.

  Further, when the automatic door ECU 24 detects that the sliding door 12 is closed when the sliding door 12 is opened, the automatic door ECU 24 determines that the vehicle 10 is in the parking state. To do. At this time, if the occupant remains in the passenger compartment 14 and it is determined that the occupant is only the infant Cc, the automatic door ECU 24 prohibits the closing operation of the sliding door 12 in response to the closing request of the sliding door 12.

  The prohibition of the closing operation prevents at least the operation of the full lock unit 40 so that the slide door 12 is not locked in the fully closed state. That is, the automatic door ECU 24 holds the slide door 12 in a fully opened state or at least a half door state.

  As a result, the opening / closing control device 22 prevents the sliding door 12 from being closed and locked in a state where only the infant Cc remains in the passenger compartment 14.

  In the vehicle 10 provided with the power sliding door device 20 configured as described above, the sliding door 12 is locked when the vehicle is parked with the main switch 26 of the power sliding door device 20 turned on. When the handle switch 54 or the remote control switch 58 is operated in the released state, the slide door 12 is opened. In the vehicle 10, the sliding door 12 is opened by operating the door switch 52 and the handle switch 54 in the passenger compartment 14 while the vehicle is stopped or parked.

  Further, in the vehicle 10, the slide door 12 is closed by operating the door switch 52, the handle switches 54 and 56, or the remote control switch 58 while the slide door 12 is opened. Thereby, in the vehicle 10, it is very easy to get on and off even when the occupant has luggage.

  By the way, in the opening / closing control device 22 that controls opening / closing of the sliding door 12, when the vehicle 10 is parked, it is confirmed whether or not the infant Cc remains in the passenger compartment 14, and the sliding door 12 is closed. I am doing so.

  FIG. 3 shows an outline of the processing at this time. This flowchart is executed when the main switch 26 is turned on and the power slide door device 20 is operable, and the slide door 12 is closed (fully closed). It is confirmed whether 12 open requests have been detected.

  Here, when the occupant operates the door switch 52, the handle switches 54, 56 or the remote control switch 58 to make an opening request for the sliding door 12, if an input of the opening request is detected, an affirmative determination is made in step 100, and the step 102.

  In this step 102, it is confirmed from the detection state of the ignition switch 28, the vehicle speed sensor 30, the brake switch 32, the parking brake switch 34 or the shift position sensor 56 whether or not the vehicle 10 is in a travel stop state (stopped or parked). To do. At this time, if the vehicle 10 is stopped, an affirmative determination is made in step 102 and the routine proceeds to step 104.

  In step 104, the lock release motor 46 is operated to unlock the slide door 12, and the drive motor 44 is operated to move the slide door 12 in the opening direction. As a result, the slide door 12 is opened, the entrance 16 is opened, and passengers can get on and off. If the vehicle 10 is traveling, a negative determination is made in step 102 and the opening operation of the sliding door 12 is terminated.

  On the other hand, when the slide door 12 is opened, in the next step 106, it is confirmed whether or not a request for closing the slide door 12 is detected. At this time, when the occupant operates the door switch 52, the handle switches 54, 56 or the remote control switch 58 in order to close the slide door 12, a closing request is input to the automatic door ECU 24.

  When the closing request is input, the automatic door ECU 24 makes an affirmative determination in step 106 and proceeds to step 108. In this step 108, the imaging device 64 is requested to detect the occupant, whereby the occupant detection process is executed.

  FIG. 4 shows an example of occupant detection processing using the imaging device 64. This flowchart is executed when occupant detection is requested from the automatic door ECU 24, and in the first step 120, the inside of the passenger compartment 14 is photographed by the camera 66. In the next step 122, predetermined image processing is performed on the image data of the photographed image. Further, in step 124, contours such as seats and passengers included in the photographed image are extracted.

  Thereafter, in step 126, occupant extraction is performed to determine whether the contour of the occupant is included from the extracted contour, and in step 128, it is confirmed whether the occupant has been extracted.

  Here, if an occupant is on board and the occupant is extracted, an affirmative determination is made at step 128 and the routine proceeds to step 130. In this step 130, it is confirmed whether or not the extracted occupant is an infant Cc. In step 132, it is confirmed whether or not the processing for all the contour images has been completed.

  By performing occupant extraction in this manner, the presence / absence of an occupant, the presence / absence of an infant Cc, the number of passengers on the vehicle 10 and the number of infants Cc are determined. When the child seat 72 is attached and the position of the child seat 72 is detected by a sensor or switch, the presence or absence of the infant Cc as a passenger is detected from the photographed image on the child seat 72, and the child seat 72 is attached. The infant Cc and other passengers may be detected separately by detecting the presence or absence of a passenger on a non-seat (passenger seat or rear seat).

  In the flowchart shown in FIG. 3, when the occupant extraction is completed, the routine proceeds to step 114, where it is confirmed whether there is no occupant in the passenger compartment 14, and when there is no occupant, an affirmative determination is made at step 114 and the routine proceeds to step 110. Then, the sliding door 12 is closed based on the closing request.

  If an occupant is detected in the passenger compartment 14, a negative determination is made in step 114, and the routine proceeds to step 116. In this step 116, it is confirmed whether or not the extracted occupant is only the infant Cc. At this time, if the extracted occupant is not the infant Cc, or is not only the infant Cc, such as an infant Cc, an affirmative determination is made at step 116 and the routine proceeds to step 110, where the sliding door 12 based on the closing request is obtained. The closing operation is performed.

  On the other hand, when the detected occupant is only the infant Cc, an affirmative determination is made at step 116 and the routine proceeds to step 118. In this step 118, the closing operation of the slide door 12 is prohibited. At this time, an alarm or chime indicating that the closing operation of the slide door 12 is prohibited may be performed together with processing such as flowing from the speaker 62.

  When the automatic door ECU 24 prohibits the closing operation of the sliding door 12, the automatic door ECU 24 proceeds to step 106 and confirms again whether or not the closing request is detected. Thus, the closing operation of the sliding door 12 is prohibited until the infant Cc is lowered from the vehicle 10, and the sliding door 12 is closed when the infant Cc is lowered from the vehicle 10 or an adult rides with the infant Cc. be able to.

  Therefore, it is possible to prevent the sliding door 12 from being closed and locked with only the infant Cc left in the passenger compartment 14.

  In general, the indoor environment such as the temperature (room temperature) in the passenger compartment 14 when the vehicle 10 is parked changes under the influence of the environment outside the vehicle. For example, in the vehicle 10 parked under a hot sun with a high outside temperature, the temperature in the vehicle compartment 14 increases as the parking time becomes longer, and the environment in the vehicle compartment 14 deteriorates. If an occupant remains in the passenger compartment 14 under such an environment, poor physical condition or the like is caused.

  Further, in the vehicle 10, the power slide door device 20 is provided, so that the slide door 12 can be opened and closed very easily. For this reason, passengers and animals in the passenger compartment 14 are left. There is a high possibility that the slide door 12 is closed without being noticed and released from the vehicle 10.

  At this time, it is determined that the infant Cc that cannot be evacuated to the outside of the vehicle by its own force remains in the vehicle 10, thereby prohibiting the closing operation of the slide door 12, and the infant Cc is left in the vehicle 10. It is possible to prevent the occurrence of poor physical condition, and to prevent the infant Cc from being left in the passenger compartment 14 and causing poor physical condition.

For example, when the presence / absence of the child seat 72 and the attachment position are known, an infrared sensor that detects heat generated by the occupant can be used instead of the imaging device 64.

  At this time, it is confirmed whether or not there is an occupant for each of the child seat 72 and the other seats, that is, whether or not there is a response to the infrared sensor. When there is a response of the infrared sensor on the child seat 72, the infant Cc gets on When there is a response to the infrared sensor in the other seats, it can be determined that a person other than the infant Cc is on board, thereby determining the presence or absence of the infant Cc and the presence or absence of a passenger other than the infant Cc. it can.

  Further, as the occupant detection means, a seat switch may be provided in each of the driver seat, the passenger seat, and the rear seat, and the presence or absence of the occupant seating may be detected by the seat switch. At this time, the seat switch determines whether or not the child seat 72 is attached, and when the child seat 72 is attached, the presence or absence of the infant Cc is determined from only the child seat 72 and the change in weight when the infant Cc is placed on the child seat 72. The configuration can be applied. Accordingly, it is possible to determine whether or not there is another occupant as well as whether or not the infant Cc is on board using the seat switch as the occupant detection means.

  Furthermore, in the present embodiment, the closing operation of the sliding door 12 is prohibited when only the infant Cc is in the vehicle. However, the present invention is not limited to this, and at least the sliding door 12 is fully closed to be in the locked state. Anything that prohibits it is acceptable. That is, when the locked state is prohibited, the slide door 12 becomes a half-door state, and locking becomes difficult. As a result, the vehicle 10 is locked and the occupant (driver) cannot leave the vehicle 10, so that the infant Cc can be prevented from being left on the vehicle 10.

  In the present embodiment, the vehicle 10 that opens and closes the entrance 18 with the slide door 12 has been described as an example. However, the present invention is not limited to this, and the swing of a slide door, a front hinge door, or the like that is opened and closed by a manual operation. It may be applied to the door. At this time, it is sufficient that at least the sliding door and the swing door are prohibited from being fully locked. Thereby, when it is going to close a swing door, it will be in the half door state which is difficult to lock, and it can prevent that a crew member leaves from a vehicle in the state where baby Cc is on board.

  In addition, changes in the environment inside the passenger compartment 14 are greatly influenced by the environment outside the vehicle, such as outside air temperature and solar radiation. From here, environmental condition detection means such as an outside air temperature sensor for detecting the outside air temperature and a solar radiation sensor for detecting the amount of solar radiation are provided, and when it is determined from the detection result of the environment condition detection means that the environment in the vehicle interior deteriorates, the slide The closing operation of the door 12 may be prohibited.

  That is, when it is determined that only the infant Cc remains in the passenger compartment 14 and the environment outside the vehicle deteriorates the environment in the passenger compartment 14, the closing operation of the slide door 12 is prohibited. Also good.

  Furthermore, in this embodiment, the slide door 12 that is a door for opening and closing the entrance 16 is applied as an opening / closing body, but the present invention is not limited thereto, and a window glass such as a door glass is applied as an opening / closing body, The present invention may be applied to a window opening / closing mechanism such as a door window or a power window device that opens / closes a window by operating a switch. As a result, the window glass is closed while the infant Cc in the passenger compartment 14 remains. The interior of the passenger compartment 14 is not sealed, and parking with the infant Cc remaining can be prevented.

  Further, in the present embodiment, the description has been made by applying the vehicle 10 in which the sliding door 12 is provided in the driver seat and the passenger seat, but the present invention is not limited to this and can be applied to a vehicle having an arbitrary configuration. it can.
