[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there can be a central component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0055] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this application and in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this application includes any and all combinations of one or more of the related listed items.

[0056] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0057] The present application proposes a vehicle, which may be an electric vehicle, a fuel vehicle, or a hybrid vehicle. The vehicle may be a sedan, an off-road vehicle, or a truck, and the present application does not limit this.

[0058] The vehicle includes a vehicle body, vehicle doors and door locks. The vehicle body is the supporting frame of the vehicle and is used to support and connect the various parts of the vehicle. The vehicle door is movably arranged on the vehicle body. The door lock is arranged between the vehicle door and the vehicle body and is used to lock the vehicle door to the vehicle body.

[0059] Please refer to Figure 1 The door lock 100 includes a lock body (not shown in the figure) and a lock ring 1. The lock body is fixed to the vehicle door, and the lock ring 1 is fixed to the vehicle body. The lock body includes a lock body and a lock tongue movably arranged on the lock body. The lock body is fixedly connected to the vehicle body, and the lock tongue can move relative to the lock body. When the vehicle door is closed, the lock tongue extends into the lock ring 1 to lock the vehicle door and the vehicle body. When the vehicle door needs to be opened, the lock tongue leaves the lock ring 1 to release the vehicle door.

[0060] The position of the lock ring 1 determines the holding force between the door and the body. When the lock ring 1 is set close to the outside of the body, the interference between the door and the body is small, and the door is easy to open and close. However, when the vehicle is wading, muddy water outside the vehicle can easily enter the cockpit of the vehicle through the gap between the door and the body, affecting driving safety. When the lock ring 1 is set close to the inside of the vehicle, the interference between the door and the body is large, and the door has good sealing, but the door is difficult to open and close, and during the opening and closing process, the door lock makes a loud noise, and the door is not comfortable to use.

[0061] In order to solve the above problems, in the present application, the vehicle body is also provided with a slide groove, and the lock ring 1 is slidably arranged in the slide groove. The slide groove has a first position and a second position, and the second position is closer to the inside of the vehicle than the first position. The door lock also includes a driving device 2, and the driving device 2 is used to drive the lock ring 1 to move between the first position and the second position. When the vehicle is not wading (the wading depth is zero) or the vehicle is wading, but the wading depth is less than a preset threshold, the lock ring 1 remains in the first position close to the outside of the vehicle, so as to reduce the interference between the door and the body, reduce the difficulty of opening the door, and improve the quietness of opening the door. When the wading depth of the vehicle is greater than the preset threshold, the driving device 2 drives the lock ring 1 to move from the first position to the second position, so as to increase the interference between the door and the body, improve the sealing of the door, and reduce the possibility of external water entering the body.

[0062] The driving device 2 can be a cylinder or an electric cylinder, and this application does not limit this. In one embodiment of the present application, the driving device 2 includes a motor 21, a gear 22 and a rack 23, and the gear 22 and the rack 23 are meshed and connected to the motor 21. The rack 23 is slidably arranged in the slide groove. The lock ring 1 is arranged on the rack 23 and can slide along the slide groove with the rack 23. The motor 21 can drive the driving gear 22 to rotate by rotating itself, and drive the driving rack 23 to slide by rotating the driving gear 22, and finally drive the lock ring 1 to move by driving the rack 23. Compared with other methods, the driving method of the motor 21, the gear 22 and the rack 23 has higher driving accuracy, better driving quietness and better user experience. The present application drives the lock ring 1 to move through the driving device 2. When the wading depth of the vehicle is greater than the preset threshold, the lock ring 1 moves from the first position to the second position under the action of the driving device 2. The door will also move toward the inner side of the vehicle under the drive of the lock tongue inserted in the lock ring 1, thereby increasing the interference between the door and the vehicle body, increasing the holding force of the door, improving the sealing performance of the door, and reducing the possibility of external muddy water entering the interior of the vehicle. When the vehicle is in a normal driving state, the lock ring 1 will be located in the first position, so as to reduce the interference between the door and the vehicle body, reduce the holding force of the door, and extend the service life of the door.

[0063] In one possible implementation of the present application, the slide groove also includes a third position, and the third position is closer to the outside of the vehicle than the first position. When the vehicle controller receives the door unlocking signal, the controller will first control the drive device 2 to drive the lock ring 1 to move from the first position to the third position, and then control the door lock to unlock. In this way, the difficulty of unlocking the door is further reduced and the quietness of unlocking the door is improved. Similarly, when the door is closed and the door lock is re-locked, the controller will also control the drive device 2 to drive the lock ring 1 to move from the third position to the first position, so as to improve the sealing of the door to the vehicle body and reduce the impact of external wind noise on the occupants when the vehicle is driving.

[0064] Please refer to Figure 2 The vehicle also includes a controller 1001, a communication bus 1002, a user interface 1003, a network interface 1004 and a memory 1005. The communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 is mainly used for users to interact with data. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface and a wireless interface. The network interface 1004 is mainly used for data communication with a network server. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wi reless-Fidel ity, Wi-Fi) interface).

[0065] The controller 1001 is used to call computer instructions to execute the control method of the door lock. The controller 1001 can be a central processing unit (CPU), and the controller 1001 can also be other general controllers, digital signal controllers (DSP), application specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc.

[0066] The memory 1005 is used to store computer instructions. The memory 1005 is used to store an operating system, a network communication module, a user interface module, and a door lock control program. The memory 1005 can be a volatile memory or a non-volatile memory, or can include both volatile and non-volatile memories. Among them, the non-volatile memory can be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), or a flash memory. The volatile memory can be a random access memory (RAM), which is used as an external cache. By way of example but not limitation, many forms of RAM are available, such as static random access memory (SRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate synchronous dynamic random access memory (DDR SDRAM), enhanced synchronous dynamic random access memory (ESDRAM), synchronous link dynamic random access memory (SLDRAM) and direct memory bus random access memory (Direct Rambus RAM, DR RAM).

[0067] It should be noted that when the controller 1001 is a general controller, DSP, ASIC, FPGA or other programmable logic device, discrete gate or transistor logic device, discrete hardware component, the memory (storage module) is integrated in the controller.

[0068] It should be noted that the memory described herein is intended to include, without being limited to, these and any other suitable types of memory.

[0069] In addition to the data bus, the bus may also include a power bus, a control bus, a status signal bus, etc. However, for the sake of clarity, various buses are marked as buses in the figure.

[0070] Please refer to Figure 3The vehicle also includes a control device, which is applied to the vehicle, and the control device includes: an acquisition module and a drive module; the acquisition module is used to acquire the wading depth of the vehicle; the drive module is used to control the position of the door lock based on the wading depth of the vehicle. When the vehicle is not wading (the wading depth is zero) or the vehicle is wading, when the wading depth is less than a preset threshold, the control device controls the lock ring to remain in the first position close to the outside of the vehicle, so as to reduce the interference between the door and the body, reduce the difficulty of opening the door, and improve the quietness of opening the door. When the wading depth of the vehicle is greater than the preset threshold, the control device drives the lock ring to move from the first position to the second position, so as to increase the interference between the door and the body, improve the sealing of the door, and reduce the possibility of external water entering the body.

[0071] Hereinafter, the control method of the door lock will be described in detail with reference to the accompanying drawings.

[0072] Please refer to Figure 4 , Figure 4 This is a flow chart of a first embodiment of a door lock control method provided by the present application. In this embodiment, the door lock control method includes the following steps:

[0073] S101: Obtain the wading depth of the vehicle.

[0074] It should be noted that the wading depth of a vehicle refers to the distance between the contact point of the vehicle tire and the highest water level on the ground. The wading depth of a vehicle can be monitored by a water level detector or by image analysis and detection by a visual camera, and this application does not limit this.

[0075] S102: Control the position of the vehicle door based on the wading depth of the vehicle.

[0076] In the technical solution of the present application, the controller can adjust the relative position of the vehicle door and the vehicle body according to the wading depth of the vehicle, and adjust the sealing degree of the vehicle door to the vehicle body by adjusting the relative position of the vehicle door and the vehicle body. In this way, the problem of the difficulty in balancing the sealing performance of the vehicle door when wading and the convenience of using the vehicle door can be solved.

[0077] There are many ways to control the position of the door. The door can be directly connected to the door through a motor or a cylinder, so that the door can be driven to move by the motor or the cylinder to control the position of the door. In one embodiment of the present application, the door has a door lock, and controlling the position of the door includes:

[0078] The position of the vehicle door is controlled by controlling the position of the door lock.

[0079] This embodiment controls the position of the vehicle door by controlling the position of the vehicle door lock, thereby reducing the control cost of the vehicle door position, reducing the space occupied by the vehicle door position control structure, and improving the riding comfort of the passengers.

[0080] Specifically, please refer to Figure 5 , Figure 5 This is a flow chart of a second embodiment of the door lock control method provided by the present application. Controlling the position of the vehicle door by controlling the position of the door lock includes the following steps:

[0081] S1021. When the wading depth is greater than a preset threshold, the lock ring of the door lock is driven to move from the first position to the second position, and the second position is closer to the inner side of the vehicle than the first position.

[0082] S1022: When the wading depth is less than a preset threshold, based on the locked state of the door lock, control the target position of the lock ring of the door lock.

[0083] In this embodiment, the preset threshold of the wading depth is used as the boundary of the movement position of the door lock ring. When the wading depth of the vehicle is greater than the preset threshold, the driving device drives the lock ring to move from the first position to the second position, thereby increasing the interference between the door and the vehicle body, improving the sealing of the door, and reducing the possibility of external water entering the vehicle body. When the wading depth of the vehicle is less than the preset threshold, the controller will control the target position of the door lock ring based on the locking state of the door lock. In this way, the problem of the difficulty in balancing the sealing of the door when wading and the convenience of using the door can be solved.

[0084] It should be noted that the preset threshold is related to the height of the vehicle chassis. The higher the height of the vehicle chassis, the larger the preset threshold, and the lower the height of the vehicle chassis, the smaller the preset threshold. Generally speaking, the preset threshold is best within the range of two-thirds to three-quarters of the distance from the bottom of the door to the point where the vehicle tire touches the ground. Exceeding this range may cause the lock ring to move untimely, affecting the air tightness of the vehicle. Below this range, the lock ring movement may be triggered frequently, increasing the energy consumption of the vehicle.

[0085] The locked state of the door lock includes the unlocked state and the locked state. When the door lock is in the locked state, the lock tongue of the door lock body extends into the lock ring, and the car door is locked to the car body by the door lock. When the door lock is in the unlocked state, the lock tongue of the door lock body is pulled out from the lock ring, and the car door can be opened and closed freely relative to the car body. There are many ways to obtain the locked state of the door lock. A sensor can be set in the lock body. The sensor is used to sense the position of the lock tongue. By sensing the position of the lock tongue, the locked state of the door lock is obtained. The locked state of the door lock can also be obtained by using a visual camera to collect the coordination between the lock tongue and the lock ring, thereby obtaining the locked state of the door lock.

[0086] There are many ways for the controller to control the target position of the door lock ring based on the door lock state. Please refer to Figure 6 , Figure 6This is a flow chart of a third embodiment of the door lock control method provided by the present application. In one possible implementation mode of the present application, based on the locked state of the door lock, controlling the target position of the lock ring of the door lock includes the following steps:

[0087] S10221. After receiving the door lock unlocking signal and before the door lock switches from the locked state to the unlocked state, the lock ring is controlled to move to a third position, and the third position is closer to the outside of the vehicle than the first position.

[0088] S10222. After the door lock is switched from the unlocked state to the locked state, the lock ring is controlled to move from the third position to the first position.

[0089] This embodiment introduces a third position, which is closer to the outside of the vehicle than the first position. When the vehicle controller receives a door unlocking signal, the controller first controls the drive device to drive the lock ring to move from the first position to the third position, and then controls the door lock to switch from the locked state to the unlocked state. In this way, the difficulty of unlocking the door is further reduced and the quietness of unlocking the door is improved. Similarly, when the door is closed and the door lock switches from the unlocked state to the locked state, the controller will also control the drive device to drive the lock ring to move from the third position to the first position, so as to improve the sealing of the door to the vehicle body and reduce the impact of external wind noise on the occupants when the vehicle is driving.

[0090] It can be understood that in other possible implementations of the present application, the slide groove of the vehicle body may also include a fourth position, and the fourth position is closer to the inside of the vehicle than the first position, and closer to the outside of the vehicle body than the second position. After the controller receives the door lock unlocking signal, the controller will first control the drive device to drive the lock ring to move from the second position to the first position, and then control the door lock to switch from the locked state to the unlocked state. In this way, the difficulty of unlocking the door is further reduced and the quietness of unlocking the door is improved. When the door is closed and the door lock switches from the unlocked state to the locked state, the controller will also control the drive device to drive the lock ring to move from the first position to the fourth position, so as to improve the sealing of the door to the vehicle body and reduce the impact of external wind noise on the occupants when the vehicle is driving.

[0091] In order to prevent the door ring from switching back and forth between the first position and the second position when the vehicle passes through multiple wading areas, in one possible implementation mode of the present application, after the lock ring of the door lock moves from the first position to the second position, the following steps are further included:

[0092] When the wading depth is less than a preset threshold, and the state of the wading depth being less than the preset threshold is maintained for a preset time, the lock ring of the door lock is driven to move from the second position to the first position.

[0093] In this embodiment, when the vehicle leaves the wading area, the controller will not immediately control the lock ring to move from the second position to the first position, but will wait for a preset time. If the wading depth of the vehicle is no longer greater than a preset threshold within the preset time, the controller will control the lock ring to move from the second position to the first position. In this way, the door ring is prevented from switching back and forth between the first position and the second position when the vehicle passes through multiple wading areas, thereby reducing the vehicle's energy consumption and extending the service life of the lock ring.

[0094] The preset time should not be set too long or too short. If it is too short, the vehicle will end the "wading mode" too early, affecting the sealing of the vehicle. If it is too long, the lock ring will be in the second position for a long time, affecting the service life of the door. In one embodiment of the present application, the preset time is set to 30s-1min, so that it can ensure that the vehicle will not end the "wading mode" too early and avoid frequent movement of the lock ring.

[0095] To improve the safety of users' vehicles, please refer to Figure 7 , Figure 7 This is a flow chart of a fourth embodiment of the door lock control method provided by the present application. In one possible implementation mode of the present application, the door lock control method further includes the following steps:

[0096] S201. When a door lock unlocking signal is received, the wading depth of the vehicle is obtained.

[0097] S202: When the wading depth is greater than a preset threshold, the door lock of the vehicle is prohibited from performing an unlocking action.

[0098] S203: When the wading depth is less than a preset threshold, the lock ring of the door lock is driven to move from the first position to the third position. Compared with the first position, the third position is closer to the outside of the vehicle.

[0099] This embodiment combines the vehicle wading depth with the door unlocking signal. When the wading depth is greater than a preset threshold, the door is prevented from being unlocked, thereby preventing external water from entering the vehicle body and reducing the potential safety hazards of the vehicle. When the wading depth is less than the preset threshold, the door unlocking difficulty is reduced and the door unlocking is more quiet.

[0100] In one possible implementation of the present application, prohibiting the door lock from performing an unlocking action also includes the steps of:

[0101] Remind passengers that the vehicle is in wading mode and the doors cannot be opened.

[0102] There are multiple ways to remind passengers that the vehicle has entered wading mode. The controller may display text on the central control screen to remind the driver that the vehicle has entered wading mode, or may use voice prompts to remind the driver that the vehicle has entered wading mode, or may use both the central control screen and voice prompts to remind the driver that the vehicle has entered wading mode.

[0103] This embodiment introduces a wading mode reminder. When the lock ring moves to the second position, it reminds passengers that the vehicle has entered the wading mode, thereby reducing the possibility of passengers performing misoperation of the vehicle (such as opening the door) in the wading mode, thereby improving the safety of vehicle operation.

[0104] In addition to when the passenger opens the door, in another possible implementation of the present application, the door lock control method further includes the following steps:

[0105] When the lock ring moves to the second position, the driver is reminded that the vehicle has entered wading mode.

[0106] The second position is the moving position of the lock ring when the vehicle is wading. When the lock ring enters the second position, it means that the vehicle has entered a deep water area. At this time, the controller will remind the driver through voice, alarm or text that the vehicle has entered the wading area to remind the driver to pay attention to driving safety and improve the safety of vehicle driving.

[0107] In order to prevent passengers from opening the door while the vehicle is moving, in one possible implementation of the present application, the door lock control method further includes the following steps:

[0108] When a door lock unlocking signal is received, the running status of the vehicle is obtained;

[0109] If the vehicle is in a driving state, the door lock of the vehicle door is prohibited from performing an unlocking action.

[0110] In this embodiment, when the controller receives a door lock unlocking signal, the controller will not unlock the door lock, but will obtain the vehicle's driving status. When the vehicle is in a driving state (the driving state may be that the vehicle is in a forward state or a reverse state), the controller will prohibit the door lock from being unlocked. In this way, it can prevent passengers from opening the door while the vehicle is driving and protect the safety of the passengers.

[0111] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship of terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientation or positional relationship described in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0112] What is disclosed above is only a preferred embodiment of the present application, and it certainly cannot be used to limit the scope of rights of the present application.
