[0049] Embodiments of the present application

[0050] The technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0051] It should be noted that when a component is referred to as being "fixed" to another component, it can be directly on the other component or there can be an intervening component. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or there can be an intervening component.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The use of the terms "and / or" includes a combination of one or more of the associated listed items.

[0053] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0054] The application provides a vehicle, which can be an electric vehicle, a fuel vehicle or a hybrid vehicle. The vehicle can be a car, an off-road vehicle or a truck, and the application does not limit the vehicle.

[0055] The vehicle includes a vehicle body, a vehicle door and a door lock. The vehicle body is a support framework of the vehicle and is used for supporting and connecting various part assemblies 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 for locking the vehicle door on the vehicle body.

[0056] Referring to FIG. 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 with the vehicle body, and the lock tongue is movable 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.

[0057] The position of the lock ring 1 determines the holding force between the vehicle door and the vehicle body. When the lock ring 1 is arranged close to the outer side of the vehicle body, the interference between the vehicle door and the vehicle body is small, and the vehicle door is easy to open and close. However, when the vehicle is wading, the mud outside the vehicle is also easy to enter the driver's cabin of the vehicle body from the gap between the vehicle door and the vehicle body, which affects the driving safety. When the lock ring 1 is arranged close to the inner side of the vehicle, the interference between the vehicle door and the vehicle body is large, and the vehicle door has good sealing performance, but the vehicle door is difficult to open and close, and the vehicle door makes loud noise during the opening and closing process, and the vehicle door has poor comfort.

[0058] To solve the above problems, in the application, the vehicle body is further provided with a sliding groove, and the lock ring 1 is slidably arranged in the sliding groove. The sliding groove has a first position and a second position, and the second position is closer to the inner side of the vehicle than the first position. The door lock further includes a driving device 2 for driving 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 outer side of the vehicle, so as to reduce the interference between the vehicle door and the vehicle body, reduce the difficulty of opening the vehicle door, and improve the quietness of opening the vehicle 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 vehicle door and the vehicle body, improve the sealing performance of the vehicle door, and reduce the possibility of external water entering the vehicle body.

[0059] The driving device 2 can be a pneumatic cylinder or an electric cylinder, and the application does not make any limitation in this regard. In an embodiment of the application, the driving device 2 comprises an electric motor 21, a gear 22 and a rack 23, the gear 22 and the rack 23 are in engagement and are in driving connection with the electric motor 21. The rack 23 is slidingly arranged in a sliding groove. The lock ring 1 is arranged on the rack 23 and can slide along the rack 23 in the sliding groove. The electric 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 the driving rack 23. Compared with other driving modes of the electric motor 21, the gear 22 and the rack 23, the driving precision is higher, the driving is quieter, and the user experience is better. The application drives the lock ring 1 to move by the driving device 2. When the water wading depth of the vehicle is greater than the preset threshold, the lock ring 1 is driven by the driving device 2 to move from the first position to the second position, and the door will be driven by the lock tongue arranged in the lock ring 1 to move towards the inside of the vehicle, thereby increasing the interference amount 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 mud entering the vehicle interior. When the vehicle is in a normal driving state, the lock ring 1 will be located at the first position, so as to reduce the interference amount between the door and the vehicle body, reduce the holding force of the door, and prolong the service life of the door.

[0060] In an embodiment of the application, the sliding groove further comprises a third position, which 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 driving 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 be unlocked. 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 relocked, the controller will also control the driving device 2 to drive the lock ring 1 to move from the third position to the first position, so as to improve the sealing performance of the door to the vehicle body and reduce the influence of external wind noise on the people in the vehicle when the vehicle is driving.

[0061] Please refer to FIG. 2, the vehicle further comprises a controller 1001, a communication bus 1002, a user interface 1003, a network interface 1004 and a memory 1005, and the communication bus 1002 is used to realize the connection and communication among these components. The user interface 1003 is mainly applied to data interaction of the user, and the user interface 1003 can include a display screen (Display) and an input device such as a keyboard (Keyboard). Optionally, the user interface 1003 can further include a standard wired interface and a wireless interface. The network interface 1004 is mainly applied to data communication of a network server, and the network interface 1004 can optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wireless-Fidelity, Wi-Fi) interface).

[0062] The controller 1001 is configured to invoke computer instructions to perform the control method of the door lock. The controller 1001 can be a central processing unit (CPU), and can also be other general-purpose controllers, digital signal processors (DSPs), application specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs) or other programmable logic devices, discrete gates or transistor logic, discrete hardware components, and the like.

[0063] The memory 1005 is configured to store computer instructions, and is configured to store operating systems, network communication components, user interface components, and door lock control programs, and the like. The memory 1005 can be a volatile memory or a non-volatile memory, or can include both volatile and non-volatile memories. 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 EPROM (EEPROM), or a flash memory. The volatile memory can be a random access memory (RAM) used as an external cache. By way of example, but not limitation, many forms of RAM can be used, such as static random access memory (SRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), and direct Rambus RAM (DR RAM).

[0064] It is to be understood that the controller 1001 can be a general purpose controller, a DSP, an ASIC, an FPGA, or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or a combination of these components.

[0065] It is to be understood that the memory described herein is intended to include, but is not limited to, these and any other suitable types of memory.

[0066] The bus can include a power bus, a control bus, and a status signal bus, in addition to the data bus. However, for the sake of clarity, the various buses are indicated as the bus in the figure.

[0067] Referring to FIG. 3, the vehicle further comprises a control device applied to the vehicle, the control device comprising: a processor and a driver; the processor is configured to acquire the wading depth of the vehicle; and the driver is configured 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, and the wading depth is less than a preset threshold, the control device controls the lock ring to remain in a first position close to the outside of the vehicle, so as to reduce the interference amount of the door with the vehicle body, reduce the opening difficulty of the door, and improve the quietness of the door opening. 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 a second position, so as to increase the interference amount of the door with the vehicle body, improve the sealing performance of the door, and reduce the possibility of external water entering the vehicle body.

[0068] In the following, the control method of the door lock will be described in detail in combination with the drawings.

[0069] Referring to FIG. 4, FIG. 4 is a flowchart of a first embodiment of the control method of the door lock provided by the present application. In the embodiment, the control method of the door lock comprises the following steps:

[0070] S101, acquiring the wading depth of the vehicle.

[0071] It is to be noted that the wading depth of the vehicle refers to the distance between the tire contact point of the vehicle and the highest water level of the ground. The wading depth of the vehicle can be monitored by a water level detector, or can be detected by image analysis of a visual camera, which is not limited in the present application.

[0072] S102, controlling the position of the door based on the wading depth of the vehicle.

[0073] In the technical solution of the present application, the controller can adjust the relative position of the door and the vehicle body of the vehicle according to the wading depth of the vehicle, and adjust the sealing degree of the door to the vehicle body by adjusting the relative position of the door and the vehicle body. In this way, the problem that the sealing performance and the convenience of the door are difficult to be considered when the door wades is solved.

[0074] There are various ways to control the position of the door, such as directly connecting the motor or the cylinder to the door, and driving the door to move by the motor or the cylinder to control the position of the door. In an embodiment of the present application, the door has a door lock, and the control of the position of the door includes:

[0075] The position of the door is controlled by controlling the position of the door lock.

[0076] The embodiment controls the position of the door by controlling the position of the door lock, thereby reducing the cost of controlling the position of the door, reducing the space occupied by the structure for controlling the position of the door, and improving the comfort of the passengers.

[0077] Specifically, referring to FIG. 5, which is a flowchart of a second embodiment of the method for controlling the door lock provided by the present application, the control of the position of the door by controlling the position of the door lock includes the following steps:

[0078] S1021, when the water wading depth is greater than the preset threshold, driving the lock ring of the door lock 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.

[0079] S1022, when the water wading depth is less than the preset threshold, controlling the target position of the lock ring of the door lock based on the latched state of the door lock.

[0080] The embodiment uses the preset threshold of the water wading depth as the boundary of the movement position of the lock ring of the door lock. When the water 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 amount between the door and the vehicle body, improving the sealing performance of the door, and reducing the possibility of external water entering the vehicle body. When the water wading depth of the vehicle is less than the preset threshold, the controller controls the target position of the lock ring of the door lock based on the latched state of the door lock. In this way, the problem that the sealing performance of the door and the convenience of the door are difficult to balance when the door wades through water is solved.

[0081] 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, the preset threshold is best within two-thirds to three-quarters of the distance from the bottom end of the door to the tire contact point of the vehicle. If it exceeds this range, the lock ring may not move in time, affecting the air tightness of the vehicle. If it is below this range, the lock ring may be frequently triggered, increasing the energy consumption of the vehicle.

[0082] The drop lock state of the door lock includes an unlocking state and a locking state. When the door lock is in the locking state, the lock tongue of the door lock body extends into the lock ring, and at this time the door is locked on the vehicle body by the door lock. When the door lock is in the unlocking state, the lock tongue of the door lock body is pulled out of the lock ring, and the door can be freely opened and closed relative to the vehicle body. The drop lock state of the door lock can be obtained in many ways. A sensor can be arranged in the lock body, and the sensor is used to sense the position of the lock tongue, so as to obtain the drop lock state of the door lock by sensing the position of the lock tongue. The drop lock state of the door lock can also be obtained by a visual camera collecting the cooperation condition of the lock tongue and the lock ring.

[0083] The controller controls the target position of the lock ring of the door lock based on the drop lock state of the door lock in many ways. Please refer to FIG. 6, which is a flowchart of a third embodiment of the control method of the door lock provided by the present application. In an implementable manner of the present application, controlling the target position of the lock ring of the door lock based on the drop lock state of the door lock includes the following steps:

[0084] S10221, before the door lock is switched from the locking state to the unlocking state after receiving the door unlocking signal, 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.

[0085] S10222, after the door lock is switched from the unlocking state to the locking state, the lock ring is controlled to move from the third position to the first position.

[0086] 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 driving device to drive the lock ring to move from the first position to the third position, and then control the door lock to switch from the locking state to the unlocking 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 is switched from the unlocking state to the locking state, the controller will also control the driving device to drive the lock ring to move from the third position to the first position, so as to improve the sealing performance of the door to the vehicle body and reduce the influence of external wind noise on the people in the vehicle when the vehicle is running.

[0087] It can be understood that, in other embodiments of the present application, the sliding groove of the vehicle body can further include a fourth position, which is closer to the inner side of the vehicle than the first position and closer to the outer side of the vehicle body than the second position. After the controller receives the door lock unlocking signal, the controller first controls the driving device to drive the locking ring to move from the second position to the first 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 vehicle door is further reduced, and the quietness of unlocking the vehicle door is improved. When the vehicle door is closed and the door lock switches from the unlocked state to the locked state, the controller will also control the driving device to drive the locking ring to move from the first position to the fourth position. In this way, the sealing performance of the vehicle door to the vehicle body is improved, and the influence of external wind noise on the people in the vehicle during driving is reduced.

[0088] To avoid the door ring switching back and forth between the first position and the second position when the vehicle passes through multiple water-involved areas, in an embodiment of the present application, after the locking ring of the door lock moves from the first position to the second position, the method further includes the following steps:

[0089] When the water-involved depth is less than the preset threshold value, and the state that the water-involved depth is less than the preset threshold value is maintained for a preset time, the locking ring of the door lock is driven to move from the second position to the first position.

[0090] In the present embodiment, when the vehicle leaves the water-involved area, the controller will not immediately control the locking ring to move from the second position to the first position, but will wait for a preset time. If the water-involved depth of the vehicle is not greater than the preset threshold value within the preset time, the controller will control the locking ring to move from the second position to the first position. In this way, when the vehicle passes through multiple water-involved areas, the door ring is prevented from switching back and forth between the first position and the second position, the energy consumption of the vehicle is reduced, and the service life of the locking ring is prolonged.

[0091] The preset time should not be set too long or too short. If it is too short, the vehicle will end the "water-involved mode" too early, which will affect the sealing performance of the vehicle. If it is too long, the locking ring will be in the second position for a long time, which will affect the service life of the vehicle door. In an embodiment of the present application, the preset time is set to 30s-1min. In this way, the vehicle can be prevented from ending the "water-involved mode" too early, and the locking ring can be prevented from moving frequently.

[0092] To improve the safety of users using the vehicle, please refer to FIG. 7, which is a flowchart of a fourth embodiment of the door lock control method provided by the present application. In an embodiment of the present application, the door lock control method further includes the following steps:

[0093] S201, when a door lock unlocking signal is received, the water-involved depth of the vehicle is obtained.

[0094] S202, when the water-involved depth is greater than a preset threshold value, the door lock of the vehicle door is prohibited from performing an unlocking action.

[0095] S203, when the wading depth is less than the preset threshold, the lock ring of the door lock is driven to move from the first position to the third position, and the third position is closer to the outside of the vehicle than the first position.

[0096] The embodiment combines the vehicle wading depth with the vehicle door unlocking signal, and when the wading depth is greater than the preset threshold, the vehicle door unlocking is prevented, so as to avoid external water from entering the vehicle body and reduce the safety hazard of the vehicle. When the wading depth is less than the preset threshold, the difficulty of unlocking the vehicle door is reduced, and the quietness of unlocking the vehicle door is improved.

[0097] In an embodiment of the present application, the door lock is prohibited from performing the unlocking action, and further comprising the steps of:

[0098] The vehicle personnel is reminded that the vehicle is in the wading mode and the vehicle door cannot be opened.

[0099] There are various ways to remind the vehicle personnel that the vehicle is in the wading mode. The controller can display text on the central control screen to remind the driver that the vehicle is in the wading mode, or can remind the driver that the vehicle is in the wading mode through voice prompt, or can remind the driver that the vehicle is in the wading mode through both the central control screen and voice prompt.

[0100] The embodiment introduces the wading mode reminder. When the lock ring moves to the second position, the vehicle personnel is reminded that the vehicle is in the wading mode, thereby reducing the possibility of the vehicle personnel misoperating the vehicle (such as opening the vehicle door) in the wading mode and improving the safety of vehicle operation.

[0101] In addition to when the vehicle personnel opens the vehicle door, in another embodiment of the present application, the door lock control method further comprises the following steps:

[0102] When the lock ring moves to the second position, the driver is reminded that the vehicle is in the wading mode.

[0103] 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 enters the deep water area. At this time, the controller will remind the driver that the vehicle enters the wading area through voice, alarm or text, so as to remind the driver to pay attention to driving safety and improve the safety of vehicle driving.

[0104] To avoid the vehicle personnel from opening the vehicle door during vehicle driving, in an embodiment of the present application, the door lock control method further comprises the following steps:

[0105] When the door lock unlocking signal is received, the running state of the vehicle is acquired;

[0106] If the vehicle is in the driving state, the door lock of the vehicle door is prohibited from performing the unlocking action.

[0107] In the embodiment, when the controller receives the door lock unlocking signal, the controller will not unlock the door lock, but will acquire the vehicle running state, when the vehicle is in the running state (which can be in the forward state or in the backward state), the controller will prohibit the door lock to be unlocked, so as to avoid the vehicle passengers to open the door during the vehicle running, and protect the safety of the vehicle passengers.
