Example embodiment (First embodiment)<Konfiguration des Türsteuersystems>

[0013] The following section describes in detail a door control system according to a first embodiment, with reference to the drawings. First, a configuration of the door control system according to the first embodiment is described. Fig. Figure 1 is a block diagram illustrating a configuration of the door control system according to the first embodiment.

[0014] A door control system 1 according to the first embodiment controls the opening of a motor vehicle door. However, the control of the opening of the motor vehicle door described here can also include determining whether the opening of the door by a passenger should be prevented in a situation where the passenger is about to open the door. Furthermore, the control of the opening of the motor vehicle door can include preventing a certain angle at which the door is opened.

[0015] For example, if it is determined that the passenger should be prevented from opening the door, the door control system 1 can prevent the door from opening beyond a certain angle or lock the door so that it cannot be opened at all. That is, the opening of the door can be physically restricted.

[0016] In addition, the door control system 1 can, in addition to or without executing the physical restriction described above, issue a warning to the passenger to prevent the door from being opened, thereby suppressing the opening of the door.

[0017] The door control system 1 comprises a posture information acquisition unit 11, a moving body information acquisition unit 12 and a door control unit 13.

[0018] The posture information acquisition unit 11 acquires posture information relating to a passenger's posture. The posture information acquisition unit 11 outputs the acquired posture information to the door control unit 13.

[0019] The posture information mentioned here is information that records the position of each part of the passenger's body, the degree of flexion or rotation of the joints, or similar data, and could, for example, be an image taken by photographing the passenger. In a case where the posture information is an image taken by photographing the passenger, the posture information acquisition unit 11 could, for example, be a camera for photographing the interior of the vehicle.

[0020] The term "passenger" includes not only the driver of a motor vehicle, but also any passengers.

[0021] The information acquisition unit for moving bodies 12 acquires mobile body information relating to a mobile body in the vicinity of a motor vehicle. The information acquisition unit for moving bodies 12 outputs the acquired mobile body information to the door control unit 13.

[0022] The information mentioned here about moving bodies is information that can be used to determine whether there is a moving body at least in the vicinity of the motor vehicle.

[0023] Information about moving objects can be, for example, an image taken by photographing the vehicle's surroundings, or output data from a sensor such as a laser imaging detector (LIDAR).

[0024] The mobile body mentioned here includes a motor vehicle that is not controlled by the door control system 1 according to the present embodiment, a bicycle, a motorcycle, a pedestrian and the like.

[0025] The door control unit 13 uses posture information to detect a preparatory action until the passenger performs the action of opening the vehicle door. Subsequently, the door control unit 13 uses the detected preparatory action and information about the moving body to control the opening of the vehicle door.

[0026] For example, the door control unit 13 can suppress the opening of the door by the passenger if the passenger's preparatory action is detected and the moving object is detected near the vehicle. Typically, the door control unit 13 can stop the opening movement of the door in this case.

[0027] The preparatory action mentioned here is a preparatory action performed by the passenger to open the car door and corresponds, for example, to an action in which he reaches his hand towards the door handle.

[0028] For example, if the posture information is an image taken by photographing the passenger, the door control unit 13 can recognize the preparatory action through skeletal recognition.

[0029] The information about the preparatory action described here may include, for example, information about whether the door control unit 13 has detected the preparatory action.

[0030] Furthermore, the door control unit 13 can use the information about the moving object to detect a moving object near the vehicle. Subsequently, the door control unit 13 can, for example, control the vehicle door based on whether the moving object is near the vehicle. <Betrieb des Türsteuerungssystems>

[0031] Next, the operation of the door control system according to the first embodiment, i.e., a door control method, will be described in detail using the drawings. Fig. Figure 2 is a flowchart illustrating the operation of the door control system according to the first embodiment. The following description refers accordingly to... Fig. 1 referenced.

[0032] First, the posture information acquisition unit 11 captures posture information (step ST101) and the moving body information acquisition unit 12 captures information about moving bodies (step ST102).

[0033] Here, the execution order of steps ST101 and ST102 can be reversed. Furthermore, steps ST101 and ST102 can be executed in parallel.

[0034] The posture information recorded in step ST101 and the information about the moving body recorded in step ST102 are output to the door control unit 13.

[0035] Next, the door control unit 13 uses the posture information to detect a preparatory action until the passenger performs the opening action of the car door (step ST103).

[0036] Finally, the door control unit 13 controls the opening of the door (step ST104), and the door control system 1 completes a series of operations.

[0037] For example, the door control unit 13 in ST104 can control the opening of the door in such a way that opening the door by the passenger is prevented when the passenger's preparatory action is detected and the moving body is detected near the vehicle.

[0038] As described above, according to the present embodiment, the door control system 1 controls the opening of the vehicle door by detecting the preparatory action until the passenger performs the opening action of the vehicle door.

[0039] According to such a configuration, it can be determined before the passenger performs the opening action of the vehicle whether the opening of the door by the passenger should be prevented. Thus, according to the present embodiment, the door control system 1 can prevent the occurrence of an accident caused by the opening of a vehicle door. (Second embodiment)<Konfiguration des Türsteuerungssystems>

[0040] The following section describes in detail a door control system according to a second embodiment, with reference to the drawings. First, a configuration of the door control system according to the second embodiment is described. Fig. Figure 3 is a block diagram illustrating a configuration of the door control system according to the second embodiment.

[0041] A door control system 1 according to the second embodiment controls the opening of a motor vehicle door. More precisely, the door control system 1 according to the present embodiment performs a control action to lock the door if there is a risk of an accident involving the door being opened.

[0042] The door control system 1 comprises a posture information acquisition unit 11, information acquisition unit for moving bodies 12, a door control unit 13 and a position information acquisition unit 14.

[0043] The posture information acquisition unit 11 acquires posture information relating to a passenger's posture. The posture information acquisition unit 11 outputs the acquired posture information to the door control unit 13.

[0044] The attitude information acquisition unit 11 according to the present embodiment is designed as a camera mounted in a motor vehicle. The attitude information acquisition unit 11 according to the present embodiment can, for example, be a trip recorder that records a video of the interior of the motor vehicle.

[0045] The posture information acquisition unit 11 according to the present embodiment acquires an image obtained by photographing the passenger as posture information and outputs this to the door control unit 13. That is, the posture information acquisition unit 11 according to the present embodiment photographs an image showing the passenger and outputs the image to the door control unit 13.

[0046] The information acquisition unit for moving bodies 12 acquires mobile body information relating to a mobile body in the vicinity of a vehicle. The information acquisition unit for moving bodies 12 outputs the acquired mobile body information to the door control unit 13.

[0047] The information acquisition unit for moving bodies 12 according to the present embodiment is configured as a camera that photographs the surroundings of the motor vehicle. The information acquisition unit for moving bodies 12 according to the present embodiment can, for example, be a trip recorder that records a video of the interior of the motor vehicle.

[0048] The information acquisition unit for moving bodies 12 according to the present embodiment captures an image obtained by photographing the environment of the motor vehicle as mobile body information and outputs the image to the door control unit 13.

[0049] The position information acquisition unit 14 acquires position information of the vehicle. The position information acquisition unit 14 outputs the acquired position information to the door control unit 13. The position information acquisition unit 14 according to the present embodiment is, for example, a position information acquisition system that uses an artificial satellite such as a global navigation satellite system (GNSS).

[0050] The door control unit 13 acquires the posture information from the posture information acquisition unit 11, acquires the information about the moving body from the information acquisition unit for the moving body 12, and acquires the position information from the position information acquisition unit 14. The door control unit 13 controls the opening of the door based on the acquired posture information, information about the moving body, and position information.

[0051] In particular, according to the present embodiment, the door control unit 13 determines whether the door should be locked based on the detected body posture information, information about moving bodies and position information.

[0052] Fig. Figure 4 is a block diagram illustrating a configuration of the door control unit 13 according to the present embodiment. The door control unit 13 according to the present embodiment comprises a preparation action detection unit 131, a confirmation action detection unit 132, a moving body detection unit 133, and a determination unit 134.

[0053] The preparatory action recognition unit 131 acquires the posture information from the posture information acquisition unit 11. That is, the preparatory action recognition unit 131 acquires the image obtained by photographing the passenger from the posture information acquisition unit 11.

[0054] The preparatory action detection unit 131 performs image processing of the image captured by the attitude information detection unit 11 and recognizes the preparatory action until the passenger performs the opening action of the car door.

[0055] Upon detection of the preparatory action, the preparatory action detection unit 131 reports this fact to the determination unit 134.

[0056] For example, the preparation action detection unit 131 can recognize as a preparation action an action in which the passenger reaches out their hand towards a door handle provided on a door of the vehicle. Furthermore, the preparation action detection unit 131 can, for example, recognize as a preparation action an action in which the passenger reaches out their hand towards a door open / close button provided on a door of the vehicle for opening / closing the vehicle door.

[0057] This means that the preparatory action detection unit 131 can recognize as a preparatory action an action in which the passenger reaches out his hand towards a mechanism for opening / closing the door, such as a door handle or a door opening / closing button.

[0058] The Preparation Action Recognition Unit 131 can detect the preparation action, for example, through skeletal recognition. In this case, the Preparation Action Recognition Unit 131 recognizes skeletal information of the passenger from the image obtained by photographing the passenger. This skeletal information includes, for example, information about the position of each body part of the passenger, information about the flexion angle of each joint, and the like.

[0059] In a case where the preparation action recognition unit 131 detects the preparation action through skeletal recognition, the preparation action recognition unit 131 can, for example, recognize the flexion angle of the passenger's arm joint as skeletal information. If the flexion angle of the passenger's arm joint is then equal to or greater than a predetermined value, the preparation action recognition unit 131 can recognize that the passenger has performed the preparation action.

[0060] This means that the preparatory action detection unit 131 can recognize as a preparatory action an action in which the passenger increases the bending angle of the arm joint to extend his arm towards the door opening / closing mechanism by using skeleton detection.

[0061] In a case where the preparation action recognition unit 131 detects the preparation action through skeletal recognition, the preparation action recognition unit 131 can, for example, recognize the rotation angle of the passenger's waist as skeletal information. If the rotation angle of the passenger's waist is then equal to or greater than a predetermined value, the preparation action recognition unit 131 can recognize that the passenger has performed the preparation action.

[0062] This means that the Preparatory Action Recognition Unit 131 can recognize as a Preparatory Action an action in which the passenger rotates his waist to extend his arm towards the door opening / closing mechanism by using skeleton detection.

[0063] In addition, the preparation action detection unit 131 can, for example, detect the position of the passenger's hand through image processing and recognize that the passenger has performed the preparation action when the distance between the detected hand and the door opening / closing mechanism becomes equal to or less than a predetermined value.

[0064] Furthermore, the preparation action detection unit 131 can detect the preparation action, for example, by prompting artificial intelligence (AI) to read the captured image.

[0065] The Confirmation Action Recognition Unit 132 captures the posture information from the Posture Information Acquisition Unit 11. That is, the Confirmation Action Recognition Unit 132 captures the image obtained by photographing the passenger from the Posture Information Acquisition Unit 11.

[0066] The confirmation action recognition unit 132 performs image processing on the image captured by the attitude information acquisition unit 11 and recognizes a confirmation action in which the passenger confirms the situation in the vicinity of the vehicle.

[0067] If a confirmation action is detected, the confirmation action detection unit 132 informs the destination unit 134.

[0068] The Confirmation Action Recognition Unit 132 can detect the confirmation movement, for example, through skeletal recognition. In this case, the Confirmation Action Recognition Unit 132 recognizes skeletal information of the passenger from the image obtained by photographing the passenger.

[0069] If the confirmation action recognition unit 132 detects the confirmation action through skeletal recognition, it can, for example, recognize a passenger's neck rotation angle as skeletal information. If the passenger's neck rotation angle is equal to or greater than a predetermined value, the confirmation action recognition unit 132 can recognize that the passenger has performed the confirmation action.

[0070] This means that the confirmation action recognition unit 132 can recognize as a confirmation action an action in which the passenger turns their neck in a predetermined direction to confirm the situation in the vicinity of the vehicle through skeleton detection.

[0071] Furthermore, the confirmation action recognition unit 132 can, for example, detect the position of the passenger's eyes by means of image processing and recognize that the passenger has performed the confirmation action if the position of the detected eyes is a position where the situation in the vicinity of the vehicle can be confirmed.

[0072] Furthermore, the confirmation action recognition unit 132 can recognize the confirmation action, for example, by prompting the artificial intelligence (AI) to read the captured image.

[0073] Unit 133, the moving object detection unit, receives information about moving objects from Unit 12, the moving object detection unit. That is, Unit 133 captures an image taken by Unit 12, the moving object detection unit, by photographing the vehicle's surroundings.

[0074] The mobile body detection unit 133 performs image processing of the image captured by the moving body information acquisition unit 12 in order to detect a mobile body in the vicinity of the motor vehicle. More precisely, the mobile body detection unit 133 detects a mobile body that is located within a detection range in the vicinity of the motor vehicle.

[0075] If a moving body is detected within the detection range, the moving body detection unit 133 reports this to the determination unit 134.

[0076] The mobile body detection unit 133 acquires the vehicle's position information from the position information acquisition unit 14. The mobile body detection unit 133 changes the detection range of the mobile body based on the vehicle's position information acquired by the position information acquisition unit 14.

[0077] For example, if a vehicle is on a road, the mobile body detection unit 133 can define the rear of the vehicle as the detection area for the mobile body. Such a configuration can prevent a collision with another vehicle on the road.

[0078] For example, if a vehicle is located very close to the left edge of the road, the mobile body detection unit 133 can define the right side of the vehicle as the detection area for the moving body. Conversely, if a motor vehicle is located very close to the right end of the road, the right side of the motor vehicle can be defined as the detection area for the moving body. With such a configuration, a collision with another motor vehicle traveling on the road can also be prevented.

[0079] Furthermore, the mobile body detection unit 133 can, for example, limit the detection range of a mobile body in a parking lot. With such a configuration, unnecessary door locking due to a faulty detection of the mobile body can be prevented.

[0080] The mobile body detection unit 133 can output the detection area of ​​the mobile body to the information acquisition unit for moving bodies 12. In this case, the information acquisition unit for moving bodies 12 can intensively photograph an image of the detected detection area of ​​the mobile body. Furthermore, the information acquisition unit for moving bodies 12 cannot, in this case, photograph an area that does not include the detected detection area of ​​the mobile body.

[0081] When the preparation action recognition unit 131 recognizes the preparation action, the destination unit 134 is informed of this fact by the preparation action recognition unit 131.

[0082] When the confirmation action recognition unit 132 recognizes the confirmation action, the destination unit 134 is informed by the confirmation action recognition unit 132.

[0083] When the mobile body detection unit 133 detects a mobile body within the detection range, the determination unit 134 is informed by the mobile body detection unit 133.

[0084] The determination unit 134 controls the opening of the motor vehicle door based on information regarding the preparation action, information regarding the confirmation action, and information about the moving body.

[0085] In particular, according to the present embodiment, the determination unit 134 determines to lock the door of the motor vehicle when the preparation action detection unit 131 detects the preparation action, the confirmation action detection unit 132 does not detect the confirmation action, and the moving body detection unit 133 detects the moving body within the detection range.

[0086] If the vehicle door is already in a locked state, locking the vehicle door includes maintaining that state.

[0087] That is, the determining unit 134 according to the present embodiment determines to lock the door of the motor vehicle if the passenger attempts to open the door in a situation where the moving body is near the motor vehicle and the passenger has not confirmed the outside of the motor vehicle.

[0088] In a case where the determining unit 134 determines that the door should be locked, the determining unit can, for example, communicate this fact in advance to a door locking mechanism provided in the motor vehicle. The door locking mechanism, having received the message, can then lock the vehicle door.

[0089] Fig. Figure 5 is a block diagram illustrating a configuration of the door control unit 13 according to the present embodiment.

[0090] As in Fig. As shown in Figure 5, the door control unit 13 can comprise a processing unit 135, for example a central processing unit (CPU), and a storage unit 136, for example random access memory (RAM) and read-only memory (ROM), in which programs, data, and the like for controlling the door control system 1 are stored. That is, the door control unit 13 functions as a computer and controls the door control unit 13 based on the program.

[0091] Therefore, any function block that includes the in Fig. The door control unit 13, as depicted in section 4, is configured in terms of hardware by the CPU, the memory unit, other circuits, and the like, and implemented in terms of software by a program or the like for controlling the door control system 1, which is stored in the memory unit. That is, the door control unit 13 can be implemented in various forms by hardware, software, or a combination of both.

[0092] The program also includes a set of instructions (or software code) that, when read by the computer, cause a computer to perform one or more of the functions described in the embodiment. The program may be stored on a non-volatile, computer-readable medium or a tangible storage medium. By way of example, and without limitation, the computer-readable medium or tangible storage medium includes working memory (RAM), read-only memory (ROM), flash memory, a solid-state drive (SSD) or any other storage technology, a CD-ROM, a digital versatile disc (DVD), a Blu-ray disc (registered trademark) or any other optical storage medium, a magnetic cartridge, a magnetic tape, a magnetic disk storage device, or any other magnetic storage medium. The program may be transferred on a volatile, computer-readable medium or a communication medium.Examples of temporary computer-readable or communication media include electrical, optical, acoustic, or other forms of transmitted signals. < Operation of the door control system>

[0093] Next, the operation of the door control system according to the second embodiment, i.e., a method, will be described in detail using the drawings. Fig. Figure 6 is a flowchart illustrating the operation of the door control system according to the second embodiment. The following description refers to the Fig. 3 and Fig. 4. Reference is made accordingly.

[0094] First, the position information acquisition unit 14 acquires the position information of a motor vehicle (step ST201). The acquired position information of the motor vehicle is output to the mobile body detection unit 133. Next, the mobile body detection unit 133 defines a detection area for the mobile body (step ST202).

[0095] Next, the mobile body information acquisition unit 12 captures the mobile body information (step ST203). More precisely, in step ST203, the mobile body information acquisition unit 12 photographs an image of an area encompassing the capture area defined in step ST202. The photographed image is output as mobile body information to the mobile body detection unit 133.

[0096] Next, the posture information acquisition unit 11 captures the posture information (step ST204). More precisely, in step ST203, the posture information acquisition unit 11 photographs an image of the passenger. The photographed image is output as posture information to the preparation action detection unit 131 and the confirmation action detection unit 132.

[0097] The execution sequence of step ST203 and step ST204 is not based on the one in Fig. The sequence shown is limited. For example, the door control system can execute step ST203 after executing step ST204. Furthermore, steps ST203 and ST204 can be executed in parallel.

[0098] Next, the detection unit 134 determines whether a moving body has been detected near the vehicle (step ST205).

[0099] More precisely, in step ST205, the determination unit 134 determines whether the movable body detection unit 133 has detected a movable body within the detection range.

[0100] If no moving body is detected near the vehicle (step ST205: NO), the door control system 1 terminates the series of operations.

[0101] If a moving body is detected near the vehicle (step ST205: YES), the determination unit 134 determines whether the passenger's preparatory action has been detected (step ST206).

[0102] More precisely, in step ST206, the determination unit 134 determines whether the preparation action detection unit 131 has detected the passenger's preparation action.

[0103] If the passenger's preparatory action is not detected (step ST206: NO), the door control system 1 terminates the sequence of operations.

[0104] If a preparatory action by the passenger is detected (step ST206: YES), the determination unit 134 determines whether the passenger's confirmation action has been detected (step ST207).

[0105] More precisely, in step ST207, the determination unit 134 determines whether the confirmation action recognition unit 132 has recognized the passenger's confirmation action.

[0106] When the passenger's confirmation action is detected (step ST207: YES), the door control system 1 terminates the sequence of operations.

[0107] If the passenger's confirmation action is not confirmed (step ST207: NO), the door control unit 13 determines to lock the door (step ST208), and the door control system 1 terminates the sequence of operations.

[0108] The execution order of steps ST205, ST206 and ST207 is not based on the one in Fig.The sequence shown in step 6 is limited. For example, door control system 1 can execute step ST206 before step ST205, or step ST207 before step ST205. Furthermore, steps ST205, ST206, and ST207 can be executed in parallel.

[0109] This means that the execution order of steps ST205, ST206 and ST207 can be arbitrary, as long as the door locking is determined in a case where the moving body is detected near the vehicle, the passenger's preparatory action is detected and the passenger's confirmation action is not detected.

[0110] As described above, according to the present embodiment, the door control system 1 detects the preparatory action until the passenger performs the opening action of the vehicle door, based on posture information relating to the passenger's posture. Then, according to the present embodiment, the door control system 1 determines whether the door should be locked, based on whether the preparatory action has been detected.

[0111] According to such a configuration, the door control system 1, as described in the present embodiment, can lock the vehicle door before the passenger opens it. This allows the door control system 1, as described in the present embodiment, to prevent accidents caused by opening a vehicle door. (Further examples)

[0112] In the door control system 1 according to the present disclosure, the door control unit 13 can further detect the speed of the moving object near the motor vehicle based on information about the moving object. The opening of the motor vehicle door can then be controlled based on the detected speed of the moving object.

[0113] For example, according to the present disclosure, the door control system 1 can determine not to lock the door if the distance between the detected moving body and the motor vehicle equipped with the door control system 1 is equal to or greater than a predetermined value and the speed of the detected moving body is equal to or less than a predetermined value.

[0114] According to such a configuration, the occurrence of unnecessary door locking can be suppressed.

[0115] Furthermore, in the door control system 1 according to the present disclosure, the door control unit 13 can also detect the forward direction of the moving body in the vicinity of the motor vehicle based on the information about the moving body. The opening of the motor vehicle door can then be controlled based on the detected forward direction of the moving body.

[0116] For example, according to the present disclosure, the door control system 1 can determine not to lock the door if the determined forward direction of the moving body is a direction moving away from the motor vehicle equipped with the door control system 1.

[0117] According to such a configuration, the occurrence of unnecessary door locking can be suppressed.

[0118] Furthermore, according to the present disclosure, the door control system 1 can control the opening of the door based on the vehicle's position information.

[0119] For example, according to the present disclosure, the door control system 1 can only control the opening of the right door of the motor vehicle when the motor vehicle is at the left end of the road. Similarly, according to the present disclosure, the door control system 1 can only control the opening of the left door of the motor vehicle when the motor vehicle is at the right end of the road. That is, according to the present disclosure, the door control system 1 can only control the opening of the door on the side facing the road.
