[0053] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0054] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0055] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0056] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0057] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0058] According to a first aspect of an embodiment of the present application, a vehicle door control method is provided, comprising determining a sealing reaction force between a vehicle door and a vehicle frame based on a current wading depth of the vehicle.

[0059] like Figure 1 and Figure 2 As shown, a wading sensor is provided in the vehicle, and the wading sensor is used to detect the wading depth of the vehicle. The wading sensor can adopt radar, infrared, image processing, etc.

[0060] The wading depth of a vehicle refers to the depth of the water level around the vehicle, that is, the depth of the water on the road.

[0061] When the vehicle is wading, the wading depth of the vehicle is detected by the wading sensor to adjust the sealing reaction force between the door and the frame, thereby preventing water outside the vehicle from entering the passenger compartment or cockpit through the gap between the door and the frame.

[0062] In an optional implementation manner, determining the sealing reaction force between the door and the vehicle frame based on the current wading depth of the vehicle includes:

[0063] If the wading depth of the vehicle is greater than a first preset depth, the sealing reaction force between the vehicle door and the vehicle frame is increased.

[0064] When the wading depth of the vehicle is less than the first preset depth, the wading depth will not affect the vehicle and the vehicle can pass smoothly; when the wading depth of the vehicle is greater than the first preset depth, the water on the road will have the risk of entering the passenger compartment or the cockpit through the vehicle door. Specifically, the first preset depth can be the height from the bottom of the wheel to the vehicle's door sill, or it can be slightly less than the height from the bottom of the wheel to the vehicle's door sill. When the water level does not reach the door sill, the water on the road will not affect the vehicle; when the water level is higher than the door sill, the water on the road will have the risk of entering the passenger compartment or the cockpit through the vehicle door.

[0065] First, the wading depth of the vehicle is obtained through the wading sensor;

[0066] Secondly, based on the comparison between the obtained wading depth and the first preset depth, when the wading depth is greater than the first preset depth, the sealing reaction force between the door and the frame can be increased through the suction mechanism, thereby preventing the accumulated water on the road from entering the passenger compartment or cockpit through the gap between the door and the frame.

[0067] In a preferred embodiment, before obtaining the wading depth of the vehicle, it is first determined whether the vehicle is in the ON gear, and if the vehicle is in the ON gear, the wading depth of the vehicle is obtained. The ON gear means that the vehicle is in a fully powered state, the circuits of the vehicle are all connected, and the engine is ready. When the vehicle is driving normally, it is in the ON gear.

[0068] In an optional implementation manner, if the wading depth is greater than the first preset depth, increasing the sealing reaction force between the vehicle door and the vehicle frame includes:

[0069] If the wading depth is greater than the first preset depth but less than the second preset depth, increasing the sealing reaction force to the first sealing reaction force;

[0070] If the wading depth is greater than the second preset depth, increasing the sealing reaction force to the second sealing reaction force;

[0071] The first sealing reaction force is smaller than the second sealing reaction force.

[0072] The vehicle is also provided with a second preset depth, which is greater than the first preset depth. The first preset depth may be the height from the bottom of the wheel to the vehicle's sill beam, or may be slightly less than the height from the bottom of the wheel to the vehicle's sill beam; the second preset depth is greater than the height of the sill beam.

[0073] When it is detected that the wading depth is between the first preset depth and the second preset depth, the sealing reaction force between the vehicle door and the vehicle frame is increased to the first sealing reaction force; when it is detected that the wading depth of the vehicle is greater than the second preset depth, the sealing reaction force between the vehicle door and the vehicle frame is increased to the second sealing reaction force.

[0074] In a preferred embodiment, the vehicle may also be provided with a third preset depth, which is greater than the second preset depth. When it is detected that the wading depth of the vehicle is between the second preset depth and the third preset depth, the sealing reaction force between the vehicle door and the vehicle frame is increased to the second sealing reaction force; when it is detected that the wading depth of the vehicle is greater than the third preset depth, the sealing reaction force between the vehicle door and the vehicle frame is increased to the third sealing reaction force. The third sealing reaction force is greater than the second sealing reaction force.

[0075] The first preset depth, the second preset depth, and the third preset depth are calibration values, which can be calibrated according to the height of different vehicles and the sealing reaction force of different vehicles, and can be appropriately increased or decreased according to different vehicles in actual applications. For example, a shorter vehicle can only set the first preset depth and the second preset depth; a taller vehicle can set the first preset depth, the second preset depth, and the third preset depth; an even taller vehicle can set the first preset depth, the second preset depth, the third preset depth, and the fourth preset depth. You can choose according to the needs of the vehicle.

[0076] As the wading depth increases, the sealing reaction force also increases to improve the sealing between the door and the frame, preventing water from entering the passenger compartment or cockpit through the gap between the door and the frame.

[0077] In an optional implementation, before increasing the sealing reaction force, the state of the door lock is determined, and if the door lock is in a fully locked state, the sealing reaction force is increased.

[0078] In an optional implementation, if the door lock is in a semi-locked state, the door lock is controlled to enter the fully locked state from the semi-locked state.

[0079] In an optional implementation, if the vehicle door lock is in an unlocked state, the sealing reaction force between the vehicle door and the vehicle frame is not increased by the vehicle door lock.

[0080] Among them, the door locks include fully locked, half locked and unlocked states; the fully locked state means that the door is fully locked; the half locked state means that the door is half locked and half locked; the unlocked state means that the door is open and not locked.

[0081] When the vehicle is about to enter or has entered wading, the current state of the door lock is determined. If the door lock is in a fully locked state, the sealing reaction force between the door and the frame is increased; if the door lock is in a half-locked state, the door lock is controlled to enter a fully locked state from a half-locked state, and the sealing reaction force between the door and the frame is increased; if the door is in an unlocked state, the sealing reaction force between the door and the frame is not increased through the door lock, because when the door lock is in an unlocked state, the door is in an open state, and the sealing reaction force between the door and the frame cannot be increased, and operating the door lock in an unlocked state will also cause the door to be unable to close.

[0082] Therefore, before the vehicle is about to enter or has entered wading water and the sealing reaction force between the door and the frame is increased, it is necessary to first determine the state of the door lock. When the door lock is in a fully locked state, the sealing reaction force between the door and the frame is increased; when the door lock is in a half-locked state, first control the door lock from the half-locked state to the fully locked state, and then increase the sealing reaction force between the door and the frame; when the door lock is in an unlocked state, the sealing reaction force between the door and the frame is not increased by the door lock, and the door can be closed first by manual or other suction mechanisms, and the sealing reaction force between the door and the frame is increased at the same time.

[0083] In an optional embodiment, the method for determining the fully locked state, the half-locked state and the unlocked state of the door lock includes: if the first switch of the door lock is in a disconnected state, the door lock is in a fully locked state; if the first switch of the door lock is in a connected state and the second switch of the door lock is in a disconnected state, the door lock is in the half-locked state; if the first switch of the door lock is in a connected state and the second switch of the door lock is in a connected state, the door lock is in the half-locked state.

[0084] More specifically, if Figure 2 As shown, the door lock includes a first switch and a second switch.

[0085] The first switch is a full lock switch, which is used to determine whether the door lock is in a full lock state. When the door lock is in a full lock state, the first switch is disconnected; when the door lock is in a half lock state or unlocked state, the first switch is connected; therefore, by obtaining the state of the first switch, it is possible to know whether the door lock is in a full lock state.

[0086] The second switch is a half-lock switch, which is used to determine whether the door lock is in an unlocked state. When the door lock is in an unlocked state, the second switch is in a connected state; when the door lock is in a half-locked or fully locked state, the second switch is in a disconnected state; therefore, by obtaining the state of the second switch, it is possible to know whether the door lock is in an unlocked state.

[0087] Further explanation, in the step of judging the state of the door lock, the state of the first switch is first judged. If the first switch is disconnected, the door lock is in a fully locked state, and the sealing reaction force between the door and the frame can be increased; if the first switch is connected, the door lock is in a semi-locked state or unlocked state, and then the state of the second switch is judged. If the second switch is disconnected, the door lock is in a semi-locked state, and the door lock is controlled to enter a fully locked state from a semi-locked state; if the second switch is connected, the door lock is unlocked, and the operation of increasing the sealing reaction force between the door and the frame is not performed. Therefore, the state of the first switch is judged first. When the door lock is in a fully locked state, it is no longer necessary to judge the state of the second switch, so a judgment step can be saved.

[0088] like Figure 4 , Figure 5 and Figure 6 As shown, in a specific implementation, the vehicle door control method when the vehicle is wading includes:

[0089] S01: Determine whether the vehicle is in the ON gear; if the vehicle is not in the ON gear, repeat step S01; if the vehicle is in the ON gear, proceed to step S02.

[0090] S02: Determine whether the wading depth of the vehicle is greater than the first preset depth or the second preset depth; if the wading depth of the vehicle is less than the first preset depth and less than the second preset depth, return to step S01 or repeat step S02; if the wading depth of the vehicle is greater than the first preset depth or greater than the second preset depth, enter step S03.

[0091] S03: Determine whether the door lock is in a fully locked state; if the door lock is in an unlocked state, return to step S01 or S02 or repeat step S03; if the door lock is in a half-locked state, control the door lock from the half-locked state to a fully locked state and enter step S04; if the door lock is in a fully locked state, enter step S04.

[0092] S04: Calculate the required sealing reaction force between the vehicle door and the vehicle frame according to the detected wading depth of the vehicle.

[0093] Among them, in step S04, the first sealing reaction force required for the first preset depth and the second sealing reaction force required for the second preset depth can also be calculated by an external device, and the first sealing reaction force and the second sealing reaction force can be input into the controller. If it is detected that the wading depth is between the first preset depth and the second preset depth, the first sealing reaction force is the sealing reaction force required between the vehicle door and the vehicle frame; if it is detected that the wading depth is greater than the second preset depth, the second sealing reaction force is selected as the sealing reaction force required between the vehicle door and the vehicle frame.

[0094] S05: Calculate the working current required by the driving mechanism according to the sealing reaction force required between the vehicle door and the vehicle frame in step S04.

[0095] Among them, in step S05, the working current required by the driving mechanism can also be calculated by an external device. The first sealing reaction force requires a first current value, and the second sealing reaction force requires a second current value. The first current value and the second current value are input into the controller. If the wading depth is detected to be between the first preset depth and the second preset depth, the first sealing reaction force is the sealing reaction force required between the door and the frame, and the first current value is the working current of the driving mechanism; if the wading depth is detected to be greater than the second preset depth, the second sealing reaction force is selected to be the sealing reaction force required between the door and the frame, and the second current value is the working current of the driving motor.

[0096] S06: Determine whether the working current is greater than the maximum current value. If the working current is greater than the maximum current value, the alarm operation is performed while entering step S07; if the working current is less than the maximum current, the step S07 is entered.

[0097] S07: The driving mechanism drives the locking mechanism according to the working current.

[0098] S08: Simultaneously determine whether the working current has reached the first current value or the second current value, and also determine whether the driving mechanism has reached the first estimated working time.

[0099] Specifically, when the working current is the first current value, if the working current does not reach the first current value and the driving mechanism does not reach the first estimated working time, then step S08 is repeated; if the working current does not reach the first current value and the driving mechanism reaches the first estimated working time, then step S10 is performed; if the working current reaches the first current value and the driving mechanism does not reach the first estimated working time, then step S09 is entered.

[0100] When the working current is the second current value, if the working current does not reach the second current value and the driving mechanism does not reach the first estimated working time, then repeat step S08; if the working current does not reach the second current value and the driving mechanism reaches the first estimated working time, then proceed to step S10; if the working current reaches the second current value and the driving mechanism does not reach the first estimated working time, then proceed to step S09.

[0101] S09: When the working current reaches the first current value or the second current value, but the driving mechanism has not reached the first estimated working time, it is determined whether the driving mechanism has reached the second estimated working time. If the driving mechanism has not reached the second estimated working time, step S08 is repeated; if the driving mechanism has reached the second estimated working time, step S110 is entered. The second estimated working time is less than the first estimated working time.

[0102] S10: The driving mechanism stops and performs a braking action to stop it at the current position.

[0103] S11: Determine whether the wading depth of the vehicle is less than the first preset depth, and at the same time determine whether the vehicle has exited the ON gear. If the wading depth is greater than the first preset depth and the vehicle has not exited the ON gear, repeat step S11; if the wading depth is less than the first preset depth and the vehicle has not exited the ON gear, or the wading depth is less than the first preset depth and the vehicle has exited the ON gear, or the wading depth is greater than the first preset depth and the vehicle has exited the ON gear, proceed to step S12.

[0104] S12: The driving mechanism performs a reset.

[0105] According to a second aspect of an embodiment of the present application, a suction mechanism is provided for implementing the above-mentioned vehicle door control method, wherein the suction mechanism can increase the sealing reaction force between the vehicle door and the vehicle frame.

[0106] In one embodiment, the attraction mechanism is an electromagnet, an electromagnet is provided on the vehicle door, and a magnet is provided on the vehicle frame; when the vehicle door is closed, the electromagnet can be attracted to the magnet; by increasing the current of the electromagnet, the attraction force between the electromagnet and the magnet is increased, thereby increasing the sealing reaction force between the vehicle door and the vehicle frame.

[0107] In another optional embodiment, the suction mechanism is a door lock, and the sealing reaction force between the door and the frame is increased by the door lock. In this embodiment, the sealing reaction force between the door and the frame is increased by using the door lock of the vehicle, and no other suction mechanism is required. The sealing reaction force between the door and the frame can be increased without changing the structure of the vehicle itself, and water is prevented from entering the cockpit or the passenger compartment through the gap between the door and the frame when the vehicle is wading.

[0108] In an optional implementation, the vehicle door lock includes a driving mechanism and a locking mechanism 1, wherein a driving end of the driving mechanism is connected to the locking mechanism 1, and the driving mechanism controls the magnitude of the sealing reaction force between the vehicle door and the vehicle frame by driving the locking mechanism 1.

[0109] like Figure 3 As shown, the door lock includes a driving mechanism and a locking mechanism 1. A locking ring 2 is arranged on the vehicle frame, specifically, the locking ring 2 is arranged on the side B-pillar of the vehicle. When the door lock is in a fully locked state or a half-locked state, the locking structure engages with the locking ring 2 to limit the door.

[0110] When the sealing reaction force between the vehicle door and the vehicle frame needs to be increased, the driving mechanism drives the locking mechanism 1 to rotate inwardly of the vehicle door to drive the vehicle door to move toward the vehicle body, thereby increasing the sealing reaction force between the vehicle door and the vehicle frame to prevent water from entering the cockpit or passenger compartment through the gap between the vehicle door and the vehicle frame when the vehicle is wading.

[0111] Furthermore, after the locking mechanism 1 is driven to rotate according to the sealing reaction force currently required, the driving mechanism does not perform a reset action, and the locking ring 2 is limited by the locking mechanism 1 to ensure that the door lock will not be released.

[0112] During the driving process, the corresponding sealing reaction force is increased according to the wading depth and the first preset depth or the second preset depth.

[0113] In an optional implementation, the locking mechanism 1 comprises a driving arm 12 and a locking tongue 13, wherein the driving arm 12 is hinged to the locking tongue 13, and the driving arm 12 is hinged to the driving mechanism.

[0114] The suction mechanism is a door lock, which can increase the sealing reaction force between the door and the frame when the vehicle is wading without changing the structure of the vehicle itself, so as to prevent water from flowing into the cockpit or passenger compartment through the gap between the door and the frame.

[0115] like Figure 3 As shown, the door lock includes a driving mechanism and a locking mechanism 1, and the locking mechanism 1 includes a suction pull wire 11, a driving arm 12 and a lock tongue 13. A lock ring 2 is provided on the side B-pillar of the vehicle, and the door is limited by the engagement of the lock tongue 13 and the lock ring 2. More specifically, the lock tongue 13 is installed inside the lock body of the door lock, and can drive the lock body of the door lock by hooking the lock ring 2, and the lock body drives the door to move in the direction of the vehicle body. The driving arm 12 and the suction pull wire 11, the driving arm 12 is installed inside the lock body of the door lock, the driving arm 12 is connected to the suction pull wire 11, the suction pull wire 11 is connected to the driving end of the driving mechanism, the driving mechanism pulls the suction pull wire 11 and drives the driving arm 12 to move, and the driving arm 12 pushes the lock tongue 13 to rotate counterclockwise, thereby driving the door to move in the direction of the vehicle body, and at the same time when entering the wading mode.

[0116] In an optional embodiment, the locking mechanism 1 also includes a locking arm 14, and the locking arm 14 includes a first state and a second state; in the first state, the locking arm 14 is engaged with the locking tongue 13; in the second state, the locking arm 14 is disengaged from the locking tongue 13.

[0117] To further illustrate, the locking mechanism 1 further includes a locking arm 14, which is mounted inside the lock body of the vehicle door lock. More specifically, a torsion spring is provided on the locking arm 14, which can drive the locking arm 14 to move toward the lock tongue 13 under the action of the torsion spring. When the fully locked state is reached, Figure 1 As shown, the locking arm 14 and the locking tongue 13 are engaged together to prevent the locking tongue 13 from rotating clockwise.

[0118] Among them, the locking arm 14 has a first state and a second state. The first state is that the locking arm 14 is engaged with the lock tongue 13, and the door lock is in a semi-locked state or a fully locked state; the second state is that the locking arm 14 is disengaged from the lock tongue 13, and the door lock is in an unlocked state.

[0119] Further, the locking arm 14 includes a first stop arm and a second stop arm; the first stop arm is closer to the lock tongue 13 than the second stop arm. When the first stop arm is engaged with the lock tongue 13, the door lock is in a semi-locked state; when both the first stop arm and the second stop arm are engaged with the lock tongue 13, the door is in a fully locked state.

[0120] In an optional implementation, the vehicle door lock further includes a first switch and a second switch, and the first switch and the second switch are used to detect the state of the vehicle door lock.

[0121] like Figure 2 As shown, the vehicle door lock further includes a first switch and a second switch.

[0122] The first switch is a full-lock switch, which is arranged on a side of the locking arm 14 away from the lock tongue 13 and corresponds to the position of the second stop arm; when the second stop arm is disengaged from the lock tongue 13, the second stop arm squeezes the first switch, so that the first switch is in a connected state, and the door lock is in a semi-locked state or an unlocked state; when the second stop arm is engaged with the lock tongue 13, the first switch is released by the second stop arm, so the first switch is in a disconnected state, and the door lock is in a fully locked state.

[0123] The second switch is a half-lock switch, which is arranged on the side of the locking arm 14 away from the lock tongue 13 and corresponds to the position of the first stop arm; when the first stop arm is disengaged from the lock tongue 13, the first stop arm squeezes the second switch, so that the second switch is in a connected state, and the door lock is in an unlocked state; when the first stop arm is engaged with the lock tongue 13, the second switch is released by the first stop arm, so that the second switch is in a disconnected state, and the door is in a fully locked or half-locked state.

[0124] In an optional implementation, the door lock includes a third switch, and the third switch is used to detect the state of the driving mechanism.

[0125] The door lock also includes a third switch. When the driving mechanism pulls the pull-in wire 11, the driving mechanism swings with the driving arm 12. When the driving arm 12 moves away from the initial position, the third switch will be squeezed by the driving arm 12. When the third switch is in the connected state, the driving mechanism leaves the initial position; when the third switch is in the disconnected state, the driving mechanism is in the initial position.

[0126] According to the third aspect of the embodiment of the present application, a door control system is provided for executing the above-mentioned door control method, including: a wading sensor, a controller and a suction mechanism, wherein the wading sensor is used to detect the wading depth of the vehicle; the controller is electrically connected to the wading sensor, and the controller receives detection data of the wading sensor; the suction mechanism is arranged on the door, and the suction mechanism is electrically connected to the controller, and the controller controls the suction of the suction mechanism according to the detection data.

[0127] like Figure 2 As shown, the door control system includes a water wading sensor, a controller and a suction mechanism.

[0128] The wading sensor is installed on the vehicle to detect the wading depth of the vehicle. The wading sensor can be a radar sensor, an infrared sensor, or an image processing sensor, and can provide the wading depth of the vehicle through radar, infrared, or images.

[0129] The suction mechanism is installed on the vehicle door and can make the vehicle door and the vehicle frame suck together.

[0130] The controller is installed on the vehicle and interacts with the vehicle through the CAN line. The controller is electrically connected to the wading sensor. The wading sensor transmits the acquired detection information to the controller. The controller processes the detection information and controls the operation of the suction mechanism according to the detection information.

[0131] Controller Area Network (CAN) is a serial communication protocol bus used for real-time applications, which can use twisted pair cables to transmit signals.

[0132] The first switch is electrically connected to the controller, and the controller determines the current state of the door lock by collecting the disconnection or connection of the first switch through a hard line.

[0133] The second switch is electrically connected to the controller, and the controller determines the current state of the door lock by collecting the disconnection or connection of the second switch through a hard line.

[0134] It is further explained that the resistance of the first switch and the second switch approaches 0 when they are connected, and approaches infinity when they are disconnected. The controller acquisition circuit determines whether the current switch is triggered by the on and off of the switch, and the switch of the door lock is designed to ensure that the switch is in the disconnected state under the most commonly used working condition (door closed). At this time, the acquisition circuit is in an open circuit, which makes the static power consumption of the controller smaller.

[0135] In an optional embodiment, the controller controls the working current of the driving mechanism to reach a first current value or a second current value according to the first sealing reaction force or the second sealing reaction force, so that the sealing reaction force between the vehicle door and the vehicle frame reaches the first sealing reaction force or the second sealing reaction force.

[0136] Further explanation: the sealing reaction force required between the vehicle door and the vehicle frame can be obtained according to the wading depth, which is the first sealing reaction force or the second sealing reaction force. The controller obtains the working current of the driving mechanism according to the first sealing reaction force or the second sealing reaction force, and the controller controls the driving mechanism to drive the locking mechanism 1 according to the working current, so that the sealing reaction force between the vehicle door and the vehicle frame reaches the first sealing reaction force or the second sealing reaction force, so that water will not enter the vehicle door.

[0137] The first sealing reaction force and the second sealing reaction force may be calculated by the acquired wading depth, or may be calculated by other external devices and then set in the vehicle.

[0138] The working current may be calculated by the first sealing reaction force and the second sealing reaction force, and may be set in the vehicle after being calculated by other external devices.

[0139] In an optional embodiment, before the driving mechanism drives the locking mechanism 1, the controller determines whether the working current has reached the maximum current value; if the working current is less than or equal to the maximum current value, the driving mechanism drives the locking mechanism 1 to achieve the first sealing reaction force or the second sealing reaction force between the vehicle door and the vehicle frame; if the working current is greater than the maximum current value, the driving mechanism drives the locking mechanism 1 to achieve the first sealing reaction force or the second sealing reaction force between the vehicle door and the vehicle frame, and executes an alarm at the same time.

[0140] To further illustrate, the driving mechanism may be a motor. The motor is provided with a maximum current value, which may be a maximum stall current value of the motor or a maximum operating current value of the motor.

[0141] Therefore, before the motor drives the locking mechanism 1, the controller will first determine whether the working current has reached the set maximum current value. If the working current is less than the maximum current value, the controller will control the drive mechanism to drive the locking mechanism 1; if the working current is greater than the maximum current value, the controller will control the drive mechanism to drive the locking mechanism 1 while simultaneously performing an alarm operation to remind the driver that the water pressure is too high and not to wade. The alarm can be issued through a pop-up window or voice reminder in the vehicle.

[0142] In an optional embodiment, the controller determines whether the driving mechanism reaches the first current value or the second current value and / or the first preset working time; if the first current value or the second current value and / or the first preset working time is reached, the driving mechanism stops working.

[0143] The driving mechanism is provided with a first preset working time, and the first preset working time is the time from when the driving mechanism starts to drive the locking mechanism 1 to when it stops driving the locking mechanism 1 .

[0144] When the driving mechanism is driving the locking mechanism 1 , the controller needs to determine whether the driving mechanism reaches the first current value or the second current value and / or the preset working time.

[0145] If the working current required by the driving mechanism is the first current value, when the driving mechanism reaches the first preset working time but does not reach the first current value, the driving mechanism stops working; when the driving mechanism reaches the first current value but does not reach the first preset working time, the driving mechanism stops working; when the driving mechanism reaches both the first preset working time and the first working current, the driving mechanism stops working.

[0146] If the working current required by the driving mechanism is the second current value. When the driving mechanism reaches the first preset working time but does not reach the second current value, the driving mechanism stops working; when the driving mechanism reaches the second current value but does not reach the first preset working time, the driving mechanism stops working; when the driving mechanism reaches both the first preset working time and the second working current, the driving mechanism stops working.

[0147] Further description: the first preset working time is set between 3s and 8s, preferably 5s.

[0148] It can prevent the locking mechanism 1 from being pulled apart when the drive mechanism is working, or the gear reducer of the drive mechanism from breaking and derailing, causing the drive mechanism to idle with a small current. Therefore, setting a preset working time can prevent the drive mechanism from working all the time and being burned out.

[0149] To further explain, the driving mechanism stops working and maintains the current position, and a braking action is performed on the driving mechanism to prevent the driving mechanism from continuing to drive the locking mechanism 1 due to inertia.

[0150] In an optional implementation, the wading sensor repeatedly detects the wading depth of the vehicle, and when the wading depth is less than the first preset depth, the driving mechanism performs a reset.

[0151] The controller is electrically connected to the third switch, and the controller collects the connection or disconnection of the third switch through a hard line to determine the state of the driving mechanism, so that after the vehicle finishes wading, the controller controls the driving mechanism to perform a reset.

[0152] Further, the wading sensor will repeatedly detect the wading depth of the vehicle. When it is detected that the wading depth of the vehicle is less than the first preset depth, the controller will drive the mechanism to perform a reset action. After the reset is completed, the door lock can be opened normally. When the vehicle is wading, the driving mechanism drives the locking mechanism 1 and limits the locking mechanism 1.

[0153] It is further explained that the driving mechanism performs a reset before opening the door, which can avoid problems such as door popping and door shaking when the door is opened.
