Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a control method, device, equipment, medium and program product for a vehicle tailgate. Background Art

[0002] In recent years, vehicle users have paid more and more attention to the sensory quality of vehicles. The operation of opening and closing the vehicle tailgate is the most direct experience for vehicle users. The touch and sound during the process of opening and closing the tailgate are the first things users perceive. When opening the tailgate, after unlocking, the tailgate will first bounce up at a small angle with a "bang" sound, and then the user can open it arbitrarily. If the user touches the tailgate at this time, it will cause an uncomfortable bouncing feeling, and the "bang bang" sound will affect the user experience; when closing the tailgate, the user needs to use a relatively large force to make the tailgate contact the vehicle body to close, which will also affect the user experience of the vehicle. Summary of the Invention

[0003] The purpose of the present invention is to provide a control method, device, equipment, medium and program product for a vehicle tailgate, which is used to solve the problems that users feel a bouncing feeling and "bang bang" sound when opening the tailgate, and the poor experience caused by the relatively large operating force required by users when closing the tailgate.

[0004] To solve the above technical problems, an embodiment of the present invention provides a control method for a vehicle tailgate. A lock tongue assembly is provided on the tailgate of the vehicle. The lock tongue assembly is connected to a lock tongue driving mechanism. A lock catch assembly is connected to a position corresponding to the lock tongue assembly in the vehicle body through a linear driving mechanism. Wherein, the method includes:

[0006] According to the tailgate opening signal, control the tailgate to switch from the locked state to the unlocked state by sequentially driving the linear driving mechanism to drive the lock catch assembly to linearly move in a first direction and driving the lock tongue driving mechanism to drive the lock tongue assembly to rotate in a second direction;

[0007] When the tailgate is in the unlocked state, obtain the position information detected by a sensor, where the position information is used to indicate the positional relationship between the lock tongue assembly and the lock catch assembly;

[0008] When the position information meets a preset condition, control the tailgate to switch from the unlocked state to the locked state by sequentially driving the lock tongue driving mechanism to drive the lock tongue assembly to rotate in a third direction and driving the linear driving mechanism to drive the lock catch assembly to linearly move in a fourth direction;

[0009] Wherein, in the locked state, the latch assembly and the locking tongue assembly cooperate with each other, and in the unlocked state, the latch assembly and the locking tongue assembly do not cooperate. The first direction is the direction away from the vehicle body, the fourth direction is opposite to the first direction, and the second direction and the third direction are opposite to each other.

[0013] Optionally, driving the locking tongue drive mechanism to drive the locking tongue assembly to rotate in the third direction and driving the linear drive mechanism to drive the latch assembly to linearly move in the fourth direction includes:

[0015] When the locking tongue assembly is at the third preset position, sending a fourth control signal to the linear drive mechanism to drive the linear drive mechanism to drive the latch assembly to linearly move in the fourth direction until the latch assembly is located at a fourth preset position.

[0016] Optionally, after controlling the tailgate to switch from the locked state to the unlocked state, the method further includes:

[0017] Sending a fifth control signal to the linear drive mechanism to drive the linear drive mechanism to drive the latch assembly to linearly move further in the first direction until the latch assembly is located at a fifth preset position.

[0018] An embodiment of the present invention further provides a control device for a vehicle tailgate. A latch assembly is provided on the tailgate of the vehicle. The latch assembly is connected to a latch driving mechanism. A lock catch assembly is connected by a linear driving mechanism at a position corresponding to the latch assembly in the vehicle body. Wherein, the device includes:

[0019] A first receiving module, configured to receive a tailgate opening signal sent by a terminal device when the tailgate is in a locked state;

[0020] A first control module, configured to control the tailgate to switch from the locked state to the unlocked state by sequentially driving the linear driving mechanism to drive the lock catch assembly to linearly move in a first direction and driving the latch driving mechanism to drive the latch assembly to rotate in a second direction according to the tailgate opening signal;

[0023] Wherein, in the locked state, the lock catch assembly cooperates with the latch assembly. In the unlocked state, the lock catch assembly does not cooperate with the latch assembly. The first direction is the direction away from the vehicle body. The fourth direction is opposite to the first direction. The second direction and the third direction are opposite.

[0024] An embodiment of the present invention further provides a network device, including: a processor, a memory, and a program stored on the memory and executable on the processor.

[0027] At least one of the above technical solutions of the present invention has the following beneficial effects:

[0028] In the above solution, compared with the prior art, the latch assembly of the present invention is not directly fixed to the vehicle body, but is connected to the vehicle body through a linear drive mechanism. Through the linear drive mechanism, the latch assembly can move linearly relative to the vehicle body. On this basis, a control method for the vehicle tailgate of the present invention is proposed.

[0029] In the method provided by the present invention, if the tailgate is in a locked state, when a tailgate opening signal sent by a terminal device is received, according to the tailgate opening signal, first drive the linear drive mechanism to drive the latch assembly to move linearly in a first direction, and then drive the lock tongue drive mechanism to drive the lock tongue assembly to rotate in a second direction, so as to control the tailgate to switch from the locked state to the unlocked state. Among them, the first direction is the direction away from the vehicle body; during the above tailgate unlocking process, first control the linear drive mechanism to drive the latch assembly to move linearly a certain distance in the direction away from the vehicle body, and then drive the vehicle tailgate in the locked state to move linearly in the direction away from the vehicle body, so that the tailgate first opens a small angle at a moderate speed, and then drive the lock tongue drive mechanism to drive the lock tongue assembly to rotate in the second direction, so that the lock tongue assembly and the latch assembly are switched from being matched to not being matched, and the tailgate can be opened arbitrarily. During the entire unlocking process, the tailgate first opens a small angle at a moderate speed and then is completely unlocked, which can effectively reduce the popping feeling and "bang" sound generated when the tailgate is opened, and improve the user experience.

[0030] If the tailgate is in an unlocked state, sensors pre-configured in the vehicle will detect the positions of the lock tongue assembly and the latch assembly. When the detected position information meets the preset conditions, first drive the lock tongue drive mechanism to drive the lock tongue assembly to rotate in a third direction, so that the lock tongue assembly and the latch assembly are switched from not being matched to being mutually matched, and the tailgate cannot be opened arbitrarily. Then control the linear drive mechanism to drive the latch assembly to move linearly a certain distance in the second direction, so that there is no gap between the tailgate and the vehicle body. Among them, the second direction is opposite to the first direction. When the user manually closes the tailgate, it is necessary to press the tailgate down with force until the positions of the lock tongue assembly and the latch assembly meet the conditions, and the tailgate is automatically locked. Since the linear drive mechanism drives the latch assembly to move linearly a certain distance in the direction away from the vehicle body during the tailgate unlocking process of the present invention, therefore, the user does not need too much operating force when pressing down the tailgate, which is more relaxed and improves the user experience.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] As Figures 1 to 4 shown, an embodiment of the present invention provides a vehicle tailgate switch system, including:

[0039] A latch assembly 2, which is arranged on the tailgate 1 of the vehicle;

[0040] A lock catch assembly 3, which is connected to the vehicle body 5 through a linear drive mechanism 4.

[0041] Among them, the linear drive mechanism 4 includes but is not limited to a lead screw, an electric push rod, etc.

[0042] As Figure 1 and Figure 2 shown, the lock catch assembly 3 is connected to the vehicle body 5 through the linear drive mechanism 4; the latch assembly 2 is arranged on the tailgate 1 of the vehicle; compared with the prior art, the lock catch assembly 3 can linearly move relative to the vehicle body 5 through the linear drive mechanism 4. As Figure 3 shown, this is the schematic structural diagram of the lock catch assembly 3 fixed on the vehicle body 5; as Figure 4 shown, this is the schematic structural diagram of the cooperation between the latch assembly 2 and the lock catch assembly 3 when the vehicle tailgate is in the locked state. The latch 21 in the latch assembly 2 can rotate around the mounting shaft 22. When the latch 21 meshes with the lock catch assembly 3, the latch assembly 2 and the lock catch assembly 3 cooperate with each other, and the tailgate cannot move arbitrarily.

[0043] As Figure 5As shown in the figure, an embodiment of the present invention provides a method for controlling a vehicle tailgate. A locking tongue assembly is provided on the tailgate of the vehicle. The locking tongue assembly is connected to a locking tongue driving mechanism. A locking buckle assembly is connected to a position corresponding to the locking tongue assembly in the vehicle body through a linear driving mechanism. Wherein, the method includes:

[0044] Step S501, when the tailgate is in the locked state, receive a tailgate opening signal sent by a terminal device;

[0045] In step S501, the terminal device includes but is not limited to one or more of an in-vehicle terminal, a mobile terminal, and a tailgate opening and closing device provided on the vehicle tailgate. Among them, the mobile terminal includes but is not limited to a mobile phone, a car key, etc.

[0046] Step S502, according to the tailgate opening signal, control the tailgate to switch from the locked state to the unlocked state by sequentially driving the linear driving mechanism to drive the locking buckle assembly to linearly move in a first direction and driving the locking tongue driving mechanism to drive the locking tongue assembly to rotate in a second direction;

[0047] In step S502, when the tailgate is in the locked state, the locking buckle assembly and the locking tongue assembly cooperate with each other, and the tailgate is fixed relative to the locking buckle assembly and cannot move arbitrarily; when the tailgate is in the unlocked state, the locking buckle assembly and the locking tongue assembly do not cooperate, and the tailgate can move arbitrarily relative to the vehicle body.

[0048] When the tailgate is in the locked state, the vehicle body controller, according to the tailgate opening signal, first controls the linear driving mechanism to drive the locking buckle assembly to linearly move a certain distance away from the vehicle body, and then drives the locked vehicle tailgate to linearly move away from the vehicle body, so that the tailgate opens a small angle at a moderate speed. Then, the locking tongue driving mechanism is driven to drive the locking tongue assembly to rotate in the second direction, so that the locking tongue assembly and the locking buckle assembly are switched from cooperating with each other to not cooperating. At this time, the tailgate can be opened arbitrarily. It should be noted that the second direction includes but is not limited to one of the clockwise direction and the counterclockwise direction, but the present invention does not limit the second direction, as long as the locking tongue assembly and the locking buckle assembly are switched from cooperating with each other to not cooperating.

[0049] During the entire unlocking process, the tailgate first opens a small angle at a moderate speed and then is completely unlocked, which can effectively reduce the popping feeling and "bang" sound generated when the tailgate is opened, and improve the user experience.

[0050] Step S503, when the tailgate is in the unlocked state, obtain the position information detected by the sensor, where the position information is used to indicate the position relationship between the locking tongue assembly and the locking buckle assembly;

[0051] In step S503, when the tailgate is in the unlocked state, sensors pre-configured in the vehicle will detect the positions of the latch assembly and the lock catch assembly in real time, and obtain position information indicating the positional relationship between the latch assembly and the lock catch assembly.

[0052] The sensors include, but are not limited to, one or more of a light sensor, a position detection sensor, and a pressure sensor, and the present invention does not limit this.

[0053] Step S504, when the position information meets a preset condition, control the tailgate to switch from the unlocked state to the locked state by sequentially driving the latch drive mechanism to drive the latch assembly to rotate in a third direction and driving the linear drive mechanism to drive the lock catch assembly to move linearly in a fourth direction;

[0054] Wherein, when in the locked state, the lock catch assembly and the latch assembly cooperate with each other; when in the unlocked state, the lock catch assembly and the latch assembly do not cooperate. The first direction is the direction away from the vehicle body, the fourth direction is opposite to the first direction, and the second direction and the third direction are opposite to each other.

[0055] In step S504, if the tailgate is in the unlocked state, sensors pre-configured in the vehicle will detect the positions of the latch assembly and the lock catch assembly. When the detected position information meets the preset condition, the vehicle controller first drives the latch drive mechanism to drive the latch assembly to rotate in a third direction, so that the latch assembly and the lock catch assembly switch from not cooperating to cooperating with each other. At this time, the tailgate is fixed relative to the lock catch assembly and the tailgate cannot be opened arbitrarily. Then, control the linear drive mechanism to drive the lock catch assembly to move linearly in the second direction for a certain distance, so that there is no gap between the tailgate and the vehicle body. At this time, the tailgate is completely closed. Among them, the fourth direction is opposite to the first direction. The third direction includes, but is not limited to, the other one of the clockwise direction and the counterclockwise direction, but the present invention does not limit the third direction, as long as it is opposite to the second direction and enables the latch assembly and the lock catch assembly to switch from not cooperating to cooperating with each other. The preset conditions include, but are not limited to, one or more of the distance between the latch assembly and the lock catch assembly being less than a first threshold, and the latch assembly and the lock catch assembly coming into contact or collision, and the present invention does not limit this.

[0056] If the process of making the position information of the lock catch assembly and the latch assembly meet the preset condition is a manual operation by the user, the user needs to press down the tailgate forcefully until the positional relationship between the latch assembly and the lock catch assembly meets the preset condition, and then the tailgate is automatically locked. Since in the process of unlocking the tailgate in the present invention, the linear drive mechanism drives the lock catch assembly to move linearly in the direction away from the vehicle body for a certain distance, therefore, the user does not need too much operating force when pressing down the tailgate, which is more relaxed and improves the user experience.

[0057] In an embodiment of the present invention, based on the vehicle tailgate switch system provided by the present invention, the vehicle controller can control the vehicle tailgate to switch between an unlocked state and a locked state. Moreover, during the process of controlling the tailgate to switch from the locked state to the unlocked state, it can effectively reduce the spring feeling and the "bang" sound generated when the tailgate is opened, improving the user experience. During the process of controlling the tailgate to switch from the unlocked state to the locked state, it can reduce the force required for the user to press down the tailgate operation, making it easier and improving the user experience.

[0058] Optionally, the driving the latch assembly to linearly move in a first direction by sequentially driving the linear drive mechanism and driving the latch driving mechanism to drive the latch assembly to rotate in a second direction includes:

[0059] Sending a first control signal to the linear drive mechanism to drive the linear drive mechanism to drive the latch assembly to linearly move in a first direction until the latch assembly is located at a first preset position;

[0060] When the latch assembly is located at the first preset position, sending a second control signal to the latch driving mechanism to drive the latch driving mechanism to drive the latch assembly to rotate in a second direction to a second preset position. Wherein, when the latch assembly is at the second preset position, the latch assembly and the latch component do not cooperate.

[0061] In an embodiment of the present invention, for the specific method of the vehicle controller to control the tailgate to switch from the locked state to the unlocked state, the vehicle controller first sends a first control signal to the linear drive mechanism to drive the linear drive mechanism to linearly move in a first direction, thereby driving the latch assembly to linearly move in a first direction until the latch assembly moves to the pre-set first preset position. During this process, the tailgate will open a small angle at a moderate speed. Then, the vehicle controller sends a second control signal to the latch driving mechanism to drive the latch driving mechanism to drive the latch assembly to rotate in a second direction to the pre-set second preset position, so that the latch assembly and the latch component are switched from a cooperating state to a non-cooperating state. It can effectively reduce the spring feeling and the "bang" sound generated when the tailgate is opened, improving the user experience.

[0062] Optionally, the driving the latch driving mechanism to drive the latch assembly to rotate in a third direction and driving the linear drive mechanism to drive the latch assembly to linearly move in a fourth direction includes:

[0063] Sending a third control signal to the latch driving mechanism to drive the latch driving mechanism to drive the latch assembly to rotate in a third direction to a third preset position. Wherein, when the latch assembly is at the third preset position, the latch assembly and the latch component cooperate with each other;

[0064] When the bolt assembly is in the third preset position, a fourth control signal is sent to the linear drive mechanism to drive the linear drive mechanism to drive the latch assembly to linearly move in the fourth direction until the latch assembly is in the fourth preset position.

[0065] In an embodiment of the present invention, for the specific method of the vehicle controller controlling the tailgate to switch from the unlocked state to the locked state, when the detected position information meets the preset conditions, the vehicle controller first sends a third control signal to the bolt drive mechanism to drive the bolt drive mechanism to drive the bolt assembly to rotate in the third direction to the pre-set third preset position, so that the bolt assembly and the latch assembly switch from non-cooperation to mutual cooperation. At this time, the tailgate is fixed relative to the latch assembly and the tailgate cannot be opened arbitrarily. Then, a fourth control signal is sent to the linear drive mechanism to drive the linear drive mechanism to linearly move in the fourth direction, and further drive the latch assembly to linearly move in the fourth direction to drive the tailgate to close until the latch assembly moves to the pre-set fourth preset position. At this time, there is no gap between the tailgate and the vehicle body and the tailgate is completely closed. It can reduce the force required for the user to press down the tailgate during operation, making it easier and improving the user experience.

[0066] Optionally, after controlling the tailgate to switch from the locked state to the unlocked state, the method further includes:

[0067] Send a fifth control signal to the linear drive mechanism to drive the linear drive mechanism to drive the latch assembly to linearly continue to move in the first direction until the latch assembly is in the fifth preset position.

[0068] In an embodiment of the present invention, after controlling the tailgate to switch from the locked state to the unlocked state, in order to make it easier for the user to apply less operating force when pressing down the tailgate during subsequent closing of the tailgate, a fifth control signal is sent to the linear drive mechanism to drive the linear drive mechanism to drive the latch assembly to linearly continue to move in the first direction until the latch assembly is in the fifth preset position, where the fifth preset position is greater than the first preset position.

[0074] Wherein, in the locked state, the latch assembly and the lock tongue assembly cooperate with each other; in the unlocked state, the latch assembly and the lock tongue assembly do not cooperate.
