  Here, the short distance periphery monitoring sensor 540 is a sensor for monitoring a distance of about the door width when the door is fully opened, and the long distance rear monitoring sensor 510 is a distance of more than that. This is a sensor for monitoring. “Door width” is defined as the distance from the body when the door is fully opened. Further, the long-distance rear monitoring sensor 510 is defined as one that monitors a distance farther than the distance that the short-distance peripheral monitoring sensor 540 performs sensing.

  FIG. 5 is a diagram showing an operation status of the long-distance rear monitoring sensor in the vehicle door system according to the embodiment of the present invention, and FIG. 6 is for short-range periphery monitoring in the vehicle door system according to the embodiment of the present invention. It is a figure which shows the operating condition of a sensor. The sensing area by the monitoring sensor is indicated by a shaded area.

  As shown in FIG. 5, while the vehicle 1 travels on the road, the right side monitoring sensor 520 and the left side monitoring sensor 530 sense the traveling state of the rear automobile, motorcycle, or the like. Further, when the vehicle 1 is stopped on the road shoulder or the like, the right-side monitoring sensor 520 and the left-side monitoring sensor 530 sense whether there is a vehicle approaching from the rear side for safety of door opening. Useful as information.

  FIG. 6 shows a situation in which the vehicle 1 is parked in a parking space. In such a situation, it is possible to respond by sensing only at a short distance, so the right front door range monitoring sensor 550, the right rear door The range monitoring sensor 560, the left front door range monitoring sensor 570, and the left rear door range monitoring sensor 580 are operated. These door range monitoring sensors collect information for determining whether or not to contact other vehicles when the door is opened.

  In the present embodiment, the long-distance rear monitoring sensor 510 is configured such that the right-side monitoring sensor 520 is disposed in the right side mirror portion and the left-side monitoring sensor 530 is disposed in the left side mirror portion.

A dotted line shown in (A) shows a state where the right front door 2 is closed, and a dotted line shown in (B) shows that the right front door 2 is temporarily set. The practice shown by (C) in the locked state shows a state in which the right front door 2 is completely opened.

  When the occupant gets off the vehicle 1, the vehicle door system of the present invention opens the door only slightly (if it is not recognized the occupant's safety etc.) (the door is locked halfway as shown in FIG. 7B). It is not possible. This eliminates accidents in which the passenger inadvertently opens the door and the subsequent vehicle comes into contact, and the mistake of bringing the opened door into contact with an adjacent vehicle or obstacle. For such temporary lock control, information collected by the short-distance periphery monitoring sensor 540 and the long-distance rear monitoring sensor 510 is used.

  In the present embodiment, such a temporary lock control unit will be described as an example. However, the present invention is not limited to this, and any door control unit that performs control for preventing contact of the door with an obstacle may be used. Something like that can also be used.

  The input / output unit 700 is a user interface unit in the vehicle door system of the present invention, and the key input unit 710 is provided, for example, on the operation panel of the driver's seat, so that the system can be set. With this key input unit 710, for example, the reliability status of a child or the like is set as “none”. The audio output unit 720 includes a speaker, a non-volatile storage unit that stores an alarm sound and an alarm announcement for outputting audio from the speaker, an amplification unit such as an amplifier, and the like.

  The safety confirmation operation check unit 800 checks the behavior of the occupant photographed by the image recognition unit 220. The appropriate safety confirmation operation determination unit 810 looks at the mirror when the occupant opens the door. It is judged whether the safety check operation such as turning to the top or turning the upper body and checking the surrounding situation through the window has been properly performed.

  In addition, the surrounding state analysis unit 900 obtains information from the long-distance rear monitoring sensor 510 and the short-distance peripheral monitoring sensor 540 and determines whether or not the vicinity of the vehicle 1 is in a safe state when the door is opened. It has a surrounding state determination unit 910 for determination.

  Next, the operation of the vehicle door system of the present invention configured as described above will be described. FIG. 9 is a view showing a flowchart of door opening control processing of the vehicle door system according to the embodiment of the present invention. The algorithm of the flowchart shown in FIG. 9 is only an example for implementing the vehicle door system of the present invention, and other algorithms can be used without departing from the gist of the present invention.

  In FIG. 9, when the door opening control process is started in step S100, image recognition is performed based on the image data acquired by the image information acquisition unit 200 in step S101.

  Subsequently, in step S102, it is determined whether or not the recognized image data that has been recognized is an occupant already registered in the image information database 230.

  If the determination result in step S102 is YES, the process proceeds to step S103. If the determination result in step S102 is NO, the occupant has boarded the vehicle 1 for the first time, so that the occupant is newly added to the image information database. Then, the process proceeds to step S111.

  In step S103, which proceeds when the determination result in step S102 is YES, since the occupant who has already boarded in the past is an object, the occupant reliability database 310 is referred to and the status of the occupant is investigated. It is determined whether or not the passenger is “nothing”. In this step S103, it is determined whether or not the subject occupant is a child or the like.

  When the determination result of step S103 is YES, the process proceeds to step S115, and when the determination result of step S103 is NO, the process proceeds to step S104. In step S115, which proceeds when the determination result in step S103 is YES, a subroutine corresponding to an occupant having a reliability status of “none” is executed. This subroutine will be described in detail later.

  In step S104, it is determined whether the reliability status in the occupant reliability database 310 of the target occupant is “high” or “low”. When the determination result in step S104 is “high”, the target occupant is an occupant with high reliability in the safety confirmation operation or the like, and thus the process proceeds to step 105 in order to perform door opening processing corresponding thereto.

  When the determination result in step S104 is “low”, the target occupant is a occupant with low reliability in the safety confirmation operation or the like, and therefore a test for performing the safety confirmation operation or the like properly when the door is opened. Proceed to step 114 to execute the process. In step S114, a test subroutine for testing the reliability of the target occupant is executed. This test subroutine will be described later.

  In step S105, the door touch sensor unit 400 detects which door the occupant is trying to open. In this embodiment, the detection of the open door is performed based on the door touch sensor unit 400, but the image recognition unit 220 may grasp and detect the door opening operation of the occupant.

  In step S106, the surrounding situation analysis unit 900 analyzes the surrounding situation of the vehicle 1. In step S107, the surrounding state determination unit 910 determines whether the door is opened in a safe environment.

  When the determination result in step S107 is YES, the process proceeds to step S108, and when the determination result in step S107 is NO, the process proceeds to step S109.

  In step S108, which proceeds when the determination result in step S107 is YES, since it has been found that the door is open under a safe condition, the door temporary lock control in the door control unit 600 is canceled, and the occupant's operation The door can be opened according to the situation. In step S116, the door opening control process ends.

  In step S109, which proceeds when the determination result in step S107 is NO, since the door is not opened under a safe situation, the door control unit 600 performs door temporary lock control to temporarily lock the door. In step S110, the voice output unit 720 outputs voice guidance for safety confirmation warning, and then returns to step S106.

  Next, step S111 and subsequent steps that proceed when the determination result in step S102 is NO will be described. When the result of determination in step S102 is NO, the passenger has first boarded the vehicle 1, so that the passenger is newly registered in the image information database 230 in step S111. In step S112, the occupant is newly registered in the occupant reliability database 310. In this case, the occupant reliability status is registered as “low”.

  In the next step S113, the process proceeds to a test subroutine for testing the reliability of the passenger. And a process is complete | finished by step S116.

  Next, the test subroutine in step S113 and step S114 will be described with reference to FIG. FIG. 10 is a view showing a flowchart of a test subroutine in the control process of the vehicle door system according to the embodiment of the present invention.

  In FIG. 10, when the test subroutine is started in step S200, in the subsequent step S201, the door touch sensor unit 400 detects which door the occupant is trying to open. In the present embodiment, the detection of the open door is performed based on the door touch sensor unit 400, but the image recognition unit 220 may grasp and detect the door opening operation of the occupant.

  In step S202, the appropriate safety confirmation operation determination unit 810 of the safety confirmation operation check unit 800 checks whether or not the occupant trying to open the door is appropriately performing the safety confirmation operation. The safety confirmation operation check unit 800 checks an occupant's action photographed by the image recognition unit 220.

  In step S203, the surrounding situation analysis unit 900 analyzes the surrounding situation of the vehicle 1.

  In step S204, when the occupant opens the door, the appropriate safety confirmation operation determination unit 810 performs a safety confirmation operation such as viewing the mirror, turning the neck backward, or turning the upper body to check the surrounding situation through the window. Determine if you have done it properly.

  If the determination result in step S204 is YES, the process proceeds to step S205, and one point is added to the current point of the occupant. Further, if the determination result in step S204 is NO, the process proceeds to step S212, and one point is deducted from the current point of the occupant. These points are adjusted by updating the data in the occupant reliability database 310.

  In step S <b> 206, the surrounding state determination unit 910 determines whether the door is opened in a safe environment.

  When the determination result in step S206 is YES, the process proceeds to step S207, and one point is added to the current point of the occupant. When the determination result in step S206 is NO, the process proceeds to step S213, and one point is deducted from the current point of the occupant. These points are adjusted by updating the data in the occupant reliability database 310.

  In step S208, since it is known that the door is opened under a safe condition, the door temporary lock control in the door control unit 600 is released so that the door can be opened according to the operation of the occupant.

  In step S214, since the door is not opened under a safe situation, the door controller 600 performs door temporary lock control to temporarily lock the door. In step S215, the voice output unit 720 outputs a voice message for a safety confirmation warning, and then returns to step S203.

  In step S209, the occupant reliability database 310 is referred to, and it is determined whether or not the current point of the occupant has exceeded a predetermined number of points.

  If the determination result in step S209 is YES, it can be determined that the occupant is enforcing the safety confirmation operation, so the process proceeds to step S211 and the reliability status is changed to “high”.

If the result of the determination in step S209 is NO, it can be determined that the occupant has not yet been able to carry out the safety confirmation operation, so the process proceeds to step S210, and the reliability status is maintained as is. Step S216 Now return from the subroutine.

  According to such a processing flow of the present invention, the safety awareness of the passengers with low safety awareness can be improved because the safety awareness is repeatedly and thoroughly rubbed against the passengers with low safety awareness. It becomes.

  Next, the status “none” passenger handling subroutine in step S115 will be described with reference to FIG. FIG. 11 is a flowchart of a subroutine in the control process of the vehicle door system according to the embodiment of the present invention.

  In FIG. 11, when the status “none” occupant correspondence subroutine is started in step S300, the process proceeds to step S301. In step S301, the door touch sensor unit 400 detects which door the occupant is trying to open. In the present embodiment, the detection of the open door is performed based on the door touch sensor unit 400, but the image recognition unit 220 may grasp and detect the door opening operation of the occupant.

  In step S302, since the child is a child whose reliability status is set to “none”, the door controller 600 performs door temporary lock control regardless of safety, and temporarily locks the door.

  In step S303, the surrounding situation analysis unit 900 analyzes the surrounding situation of the vehicle 1.

  In step SS304, the surrounding state determination unit 910 determines whether the door is opened in a safe environment.

  If the decision result in the step S304 is YES, the process advances to a step S305, and the door temporary lock control in the door control unit 600 is performed and released. Then, the process proceeds to step S306 and returns.

  If the determination result in step S304 is NO, the process returns to step S302 to maintain the temporary lock state of the door.

  As described above, according to the vehicle door system of the present invention, each occupant is identified by the image recognition unit, and the safety confirmation operation of the occupant is checked according to the reliability status of the occupant reliability database. It is possible to ensure safety awareness for passengers with low awareness.
