[0001] The present disclosure relates to a vehicle door lock control device, a control method for a vehicle door lock control device, and a program. [Background technology]

[0002] 2. Description of the Related Art Conventionally, there have been proposed vehicle door lock control devices capable of preventing intrusion of suspicious persons into a vehicle. The body ECU, which functions as a vehicle door lock control device, acquires vehicle surroundings information and determines whether there is a person or object approaching the vehicle based on the acquired information, thereby determining whether there is an abnormality around the vehicle. If the body ECU determines that there is an abnormality, it locks the vehicle doors. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2017-141611 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional door lock control device, the door lock operation condition is determined only by determining whether or not a person or object is approaching the vehicle, and the situation is not specified. This meant there was a risk of malfunction in situations where the driver did not intend it to occur.

[0005] The present invention has been made in consideration of the above-mentioned problems, and its purpose is to provide a vehicle door lock control device, a control method for a vehicle door lock control device, and a program that can prevent the intrusion of suspicious persons into the vehicle and more reliably ensure the safety of the vehicle's occupants. [Means for solving the problem]

[0006] The vehicle door lock control device of the present disclosure is mounted on a vehicle and controls the locking of the vehicle's doors, and is equipped with a door lock control unit that controls the locking of the doors when an occupant of the other vehicle gets out of the other vehicle and approaches the vehicle, based on input information including other vehicles around the vehicle. [Effects of the Invention]

[0007] According to the door lock control device of the present disclosure, even in a situation around the vehicle, such as when the vehicle is the victim of aggressive driving and the occupants of the vehicle are unable to move due to fear, the physical boundary between the vehicle and the occupants of another vehicle (e.g., the driver of the other vehicle) can be reliably secured, thereby preventing or mitigating damage. [Brief explanation of the drawings]

[0008] [Figure 1] FIG. 1 is a schematic explanatory diagram of a vehicle door lock system according to an embodiment. [Figure 2] FIG. 2 is a diagram illustrating the general configuration of a vehicle door lock system. [Figure 3] FIG. 3 is a functional block diagram of the vehicle door lock control device according to the embodiment. [Figure 4] FIG. 4 is a flowchart showing the operation process of the vehicle door lock system according to the embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0009] FIG. 1 is a schematic explanatory diagram of a vehicle door lock system according to an embodiment. The vehicle door lock system 10 of the embodiment has a function of automatically locking the door of the host vehicle 11 when the door 101 of another vehicle 100 parked near the host vehicle 11 opens and a person HM, who is an occupant (e.g., a driver) of the other vehicle 100, approaches the host vehicle as shown by the dashed arrow in Figure 1.

[0010] FIG. 2 is a diagram illustrating the general configuration of a vehicle door lock system. As shown in FIG. 2, the vehicle door lock system 10 includes an exterior camera unit 12, a radar unit 13, a courtesy switch unit 14, a body ECU (Electronic Control Unit) 15, a door lock unit 16, a notification unit 17, and a GNSS (Global Navigation Satellite System) unit 18.

[0011] The exterior camera unit 12 captures images of a predetermined area around the vehicle 11 and outputs the captured images to the body ECU 15. The exterior camera unit 12 includes a plurality of exterior cameras, and the exterior cameras are installed, for example, on the front, rear, left and right sides of the vehicle 11.

[0012] The multiple exterior cameras that make up the exterior camera unit 12 collectively capture images of the area around the vehicle 11 over approximately 360°. In particular, to prepare for the possibility of being a victim of tailgating, it is possible to increase the resolution of the exterior cameras capturing images in front of or behind the vehicle 11. The exterior camera unit 12 outputs images captured by the multiple exterior cameras to the body ECU 15.

[0013] The radar unit 13 includes a plurality of radar sensors. Each radar sensor emits radio waves and detects the reflected waves to measure the distance to an object.

[0014] The radar sensors constituting the radar unit 13 are provided, for example, on the front, rear, left and right sides of the vehicle 11, and detect obstacles such as people, other vehicles (and components of other vehicles such as doors), and fixed objects, as well as the distance to the obstacles, by emitting radio waves or light and detecting the reflected waves. Note that it is also possible to use sonar using sound waves instead of the radar sensors, although this reduces measurement accuracy.

[0015] In the above configuration, the exterior camera unit 12 and the radar unit 13 function as a surrounding information acquisition unit, and acquire images captured by the exterior camera unit 12 and information such as distances measured by the radar unit 13 as surrounding information.

[0016] The courtesy switch unit 14 detects whether the doors are open or closed, whether the windows are open or closed, and whether the doors are locked.

[0017] The body ECU 15 functions as a vehicle door lock control device that performs door lock control based on the images captured by the exterior camera that constitutes the exterior camera unit 12, the obstacles and distances to the obstacles detected by the radar sensor that constitutes the radar unit 13, and the detection results of the courtesy switch unit 14.

[0018] In this case, the body ECU 15 performs a process of storing the peripheral information acquired from the exterior camera unit 12 and the radar unit 13 in the memory unit 21 or a RAM (Random Access Memory) (not shown), etc. Note that the stored peripheral information can be erased after a predetermined time has elapsed, or a so-called ring buffer can be configured to hold only a predetermined amount of peripheral information and overwrite older peripheral information.

[0019] As in a normal vehicle, the body ECU 15 performs authentication by communicating between a wireless communication device (not shown) mounted on the vehicle 11 and a key with wireless communication capability carried by the user, and when it is confirmed that the user is an authorized user, it locks and unlocks the doors, functioning as a so-called keyless entry system. In this case, the body ECU 15 of the vehicle door lock system 10 has a function to automatically lock the doors of the vehicle 11 when the strength of the wireless signal from the key reaches or falls below a predetermined threshold when the user carrying the key gets out of the vehicle 11 and moves a predetermined distance away from the vehicle 11.

[0020] In addition, in this embodiment, the body ECU 15 determines whether or not a predetermined abnormal condition exists in the vicinity of the vehicle 11 based on the information output by the exterior camera unit 12 and the radar unit 13, and if a predetermined abnormal condition is detected, and if there is a door that is not locked based on the detection result of the courtesy switch unit 14, it outputs a control signal to the door lock unit 16 to lock that door.

[0021] As a result, when an abnormal condition is detected, such as when another vehicle carrying a tailgating driver stops in front of the vehicle 11, forcing the vehicle 11 to stop on the road, and the driver opens the door of the other vehicle, gets out, and approaches the vehicle 11, the body ECU 15 operates as a door lock control device to protect the occupants of the vehicle 11 from unforeseen conditions.

[0022] As shown in FIG. 2, the body ECU 15 includes a control processing unit 20, a memory unit 21, an in-vehicle communication unit 22, an input interface (IF) unit 23, and an output interface (IF) unit 24.

[0023] The control processing unit 20 of the body ECU 15 is equipped with, for example, an MPU (Micro Processing Unit), and by reading and executing programs stored in the memory unit 21 or a ROM (Read Only Memory) not shown, the control processing unit 20 not only controls the vehicle 11 under normal conditions, but also performs various calculation processes and control processes related to the detection of predetermined abnormal conditions and various controls when an abnormal condition is detected (for example, locking / unlocking the doors of the vehicle 11).

[0024] The memory unit 21 is configured using a nonvolatile memory such as a flash memory or an EEPROM (Electrically Erasable Programmable Read Only Memory), etc. The memory unit 21 functions as a working area that stores, for example, programs executed by the control processing unit 20 and data necessary for executing these programs.

[0025] The in-vehicle communication unit 22 can communicate with other in-vehicle devices via an in-vehicle network such as a CAN (Controller Area Network). In this embodiment, the in-vehicle communication unit 22 performs communication via the in-vehicle network.

[0026] The input interface unit 23 is connected via signal lines to the exterior camera unit 12, radar unit 13, courtesy switch unit 14, etc., and receives digital or analog input signals input from these devices. The input interface unit 23 samples the input signals and outputs the digital data to the control processing unit 20.

[0027] The output interface unit 24 is connected to controlled devices such as the door lock unit 16 and the notification unit 17 via signal lines, and outputs control signals to control the operation of these controlled devices in response to commands from the control processing unit 20.

[0028] The door lock unit 16 is provided on each door of the vehicle 11 and includes a mechanical mechanism for locking the doors and a motor or actuator for operating the mechanical mechanism. The door lock unit 16 locks / unlocks each door in response to a control signal (operation command) provided from the control processing unit 20 of the body ECU 15. The notification unit 17 is configured as, for example, an audio output device or an in-vehicle display, and notifies the occupants of the vehicle 11 that an abnormal state has been detected and that the doors have been locked.

[0029] The GNSS unit 18 functions as a traveling point detection unit, and determines the traveling point (e.g., latitude and longitude coordinates) of the vehicle 11 and the type of road it is traveling on (highway, expressway, or general road, etc.) based on the positioning radio waves received from positioning satellites or the output of built-in autonomous positioning sensors (gyro sensor, acceleration sensor, etc.) and the results of map matching processing.

[0030] FIG. 3 is a functional block diagram of the vehicle door lock control device according to the embodiment. In FIG. 3, the symbols in parentheses indicate the corresponding configurations in FIG. The vehicle door lock control device 40 includes a surrounding information acquisition unit 41, a traveling point detection unit 42, and a door lock control unit 43. The surrounding information acquisition unit 41 acquires surrounding information PI, which is information including other vehicles around the vehicle, and outputs the information to the door lock control unit 43.

[0031] This surrounding information PI includes information on the presence of other vehicles, information on whether the doors of the other vehicles are open or closed, and, if an occupant of the other vehicle has exited, information on the distance to the occupant, the direction of movement, etc.

[0032] The travel point detection unit 42 detects the travel point of the vehicle 11 and outputs travel point information DP to the door lock control unit 43. This travel point information DP includes information on the latitude and longitude corresponding to the travel position of the vehicle, as well as information on the type of road on which the vehicle 11 is traveling, such as an expressway, a motorway, or an ordinary road.

[0033] Based on the input surrounding information PI, the door lock control unit 43 outputs a control signal DL to the door lock unit 16 to control the locking of the doors when an occupant of another vehicle gets out of the other vehicle and approaches the host vehicle 11.

[0034] Furthermore, based on the travel location information DP, the door lock control unit 43 outputs a control signal DL to the door lock unit 16 to control the locking of the doors when the vehicle 11 stops while traveling on a highway or a motorway and an occupant of another vehicle gets out of the other vehicle and approaches the vehicle 11.

[0035] Furthermore, if the vehicle 11 is equipped with a window opening / closing unit 51 that opens and closes the windows, the door lock control unit 43 outputs a window control signal CW to the window opening / closing unit 51 to control the window opening / closing unit 51 to close the window when the door is locked and maintain the window closed.

[0036] Next, the operation of the embodiment will be described. FIG. 4 is a flowchart showing the operation process of the vehicle door lock system according to the embodiment. When the vehicle 11 is started, the vehicle door lock system 10 is activated, and the exterior camera unit 12, radar unit 13, courtesy switch unit 14, body ECU 15, door lock unit 16, notification unit 17 and GNSS unit 18 are put into operation (step S11).

[0037] First, the exterior camera unit 12 and the radar unit 13 function as peripheral information acquisition units, and the exterior camera unit 12 outputs images captured by the exterior camera to the body ECU 15, and the radar unit 13 outputs obstacles detected by the radar sensor and the distance to the obstacles to the body ECU 15 (step S12).

[0038] The GNSS unit 18 also functions as a traveling point detection unit, and determines the traveling point (e.g., latitude and longitude coordinates) of the vehicle 11 and the type of road it is traveling on (highway, motorway, or general road, etc.) based on the positioning radio waves received from positioning satellites or the output of the built-in autonomous positioning sensor and the results of map matching processing, and outputs the traveling point detection results to the body ECU 15 (step S13).

[0039] As a result, when the host vehicle 11 comes to a stop while traveling on a road, the body ECU 15 performs image recognition of the captured image output by the exterior camera unit 12 to determine whether other vehicles in the vicinity of the host vehicle 11 have stopped, whether the doors of those other vehicles have opened, and whether occupants (e.g., the driver) have gotten out (step S14).

[0040] If it is determined in step S14 that the other vehicle is not stopped, the door of the other vehicle is not open, or the door of the other vehicle is open but the occupant has not gotten out (step S14; No), the body ECU 15 transitions the processing back to step S12.

[0041] In the judgment of step S14, if another vehicle in the vicinity of the host vehicle 11 has stopped, the door of the other vehicle has opened, and an occupant has gotten out (step S14; Yes), the body ECU 15 further judges, based on the output of the radar unit 13, whether or not a person HM (see Figure 1), who is an occupant of the other vehicle, is approaching the host vehicle 11 (step S15).

[0042] In this case, it is not limited to the case where the occupant is simply approaching, but it may also be determined whether or not the occupant has approached and entered within a predetermined distance range (for example, within 1 meter from the host vehicle 11). If the occupant has not approached within the predetermined distance, the body ECU 15 considers that the occupant of the other vehicle has simply exited the other vehicle for some reason, and there is no need for the door lock control device to lock the doors.

[0043] If it is determined in step S15 that an occupant who has gotten out of the other vehicle is not approaching the host vehicle 11 (step S15; No), the body ECU 15 shifts the processing to step S14 again.

[0044] If it is determined in step S15 that an occupant who has exited another vehicle is approaching the vehicle 11 (step S15; Yes), the control processing unit 20 of the body ECU 15 determines that an abnormal condition has been detected and outputs a control signal to control the door lock unit 16 and the notification unit 17 via the output interface unit 24, and the door lock unit 16 locks each door in accordance with the control signal (operation command) given from the control processing unit 20 of the body ECU 15 (step S16).

[0045] In addition, the notification unit 17 is configured, for example, as an audio output device or an in-vehicle display, and notifies the occupants of the vehicle 11 that an abnormal condition has been detected by generating an audio signal via the audio output device or displaying the signal on the in-vehicle display, and notifies them that the doors have been locked (step S17).

[0046] In this case, as shown by the dashed frame in Figure 1, if the vehicle 11 is equipped with a window opening / closing unit (power window control device) that opens and closes the windows and is also capable of controlling the power windows, the body ECU 15 can be configured to close the windows simultaneously with the door locking and lock them to maintain that state.

[0047] In addition, to unlock the automatically executed door lock, the door can be unlocked by operating a door unlock button inside the vehicle 11, as in the normal door unlocking method.

[0048] As described above, according to this embodiment, even in a situation around the vehicle, such as when the vehicle is being tailgated and the occupants of the vehicle are unable to move due to fear, it is possible to reliably secure a physical boundary between the vehicle and the occupants of another vehicle (e.g., the driver of the other vehicle), thereby preventing or mitigating damage.

[0049] (Modification of the embodiment) In the above description, the vehicle surroundings information acquisition unit is configured using the exterior camera unit 12 and the radar unit 13, but is not limited to this.

[0050] For example, instead of the exterior camera unit 12 and radar unit 13, a three-dimensional TOF (Time Of Flight) sensor capable of scanning three-dimensional shapes and distances to each part can be used to detect abnormal conditions. Also, instead of the radar unit 13, it is possible to configure the system so that a sonar unit equipped with a plurality of sonars is used.

[0051] In the above explanation, no distinction was made between road types, but it is also possible to configure the system to determine whether or not there is an abnormality only on roads where pedestrians are normally not present, such as expressways and motorways, based on map matching processing, ETC information, etc.

[0052] Furthermore, even on expressways, if the vehicle is located in a parking area or the like, it is possible to configure the system so that it does not judge whether an abnormal condition exists, but only judges whether an abnormal condition exists in the driving lane on the main road, the passing lane, etc. By adopting such a configuration, the door is not locked more than necessary, which improves usability for the occupants.

[0053] Furthermore, the processes and controls described in the embodiments as being performed by multiple devices may be integrated and realized in one device, and conversely, the processes and controls described as being performed by one device may be configured to be realized by multiple devices working together.

[0054] In the above explanation, the detection of an abnormal state and the door locking process upon detection are initiated when the vehicle 11 is started, but it is also possible to have the process initiated when the vehicle exceeds a predetermined speed after starting, or to have the user receive a voice or other confirmation after starting and then have the process initiated by the user's manual operation or voice instruction.

[0055] The vehicle door lock system (particularly the body ECU) of the above-described embodiment is equipped with a control device such as an MPU, a storage device such as a ROM (Read Only Memory) or RAM, an external storage device configured as a semiconductor storage device such as a USB memory or SSD, a display device such as a display device, and an input device such as an operation switch, and has a hardware configuration that utilizes a normal computer.

[0056] The program executed by the vehicle door lock system (particularly the body ECU) of this embodiment can also be provided by being recorded in an installable or executable format on a computer-readable recording medium such as a USB memory, a semiconductor storage device such as an SSD, or a DVD (Digital Versatile Disk).

[0057] The program executed by the vehicle door lock system (particularly the body ECU) of this embodiment may be stored on a computer connected to a network such as the Internet and provided by being downloaded via the network. The program executed by the vehicle door lock system (particularly the body ECU) of this embodiment may be provided or distributed via a network such as the Internet.

[0058] The vehicle door lock system (particularly the body ECU) of this embodiment may be configured to be provided in a state where the program is pre-installed in a ROM or the like.

[0059] The program executed by the vehicle door lock system (particularly the body ECU) of this embodiment has a modular structure including the above-mentioned parts (door lock control unit, surrounding information acquisition unit, driving point detection unit, etc.), and in terms of actual hardware, the MPU (processor) reads and executes the program from the above-mentioned storage medium, thereby loading the above-mentioned parts onto the main memory device, and the door lock control unit, surrounding information acquisition unit, driving point detection unit, etc. can be generated on the main memory device.
