Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a vehicle control method and a vehicle. Background Art

[0002] The door locks of existing vehicles can generally be divided into two categories: mechanical door locks and electronic door locks. Mechanical door locks are connected by a mechanical structure, and electronic door locks realize door lock switches through electronic devices and circuits. Correspondingly, the door locks of vehicles generally have two opening methods: mechanical release and electric release. The door lock enters the electric release position or the mechanical release position according to user instructions. In the related art, after the door lock enters the electric release position or the mechanical release position according to the instruction, the opening method will be maintained until a user instruction indicating the switching of the opening method is received, so as to adapt to user needs. However, in the event of a vehicle collision, the vehicle may malfunction or be powered on. If the door lock remains in the electric release position at this time, the door lock can neither be opened by electric release nor by mechanical release through the external opening handle, which may cause the user to be trapped in the vehicle, posing a safety risk.

[0022] Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings.

[0023] Combination Figure 1 As shown, an embodiment of the present application provides a vehicle, including a control system 10 and a door lock 20. In some embodiments, the control system is a vehicle controller. In other embodiments, the control system may be other controllers.

[0024] In some embodiments, the vehicle further includes a collision sensor 30 connected to the control system 10, for sensing whether the vehicle collides, generating a sensing signal, and transmitting the sensing signal to the control system 10. When a collision of the vehicle is sensed, the sensing signal includes a collision signal.

[0025] In some embodiments, the vehicle includes a door controller 40, a door handle driving device 50, and a door handle 60. The door controller 40 is electrically connected to the control system 10. The door handle driving device 50 is electrically connected to the door controller 40 and the door handle 60. In some embodiments, the door handle 60 is embedded, and the door controller 40 receives instructions from the control system 10 to control the door handle driving device 50 to eject or retract the door handle 60.

[0026] In some embodiments, the vehicle further includes a door lock motor 70 electrically connected to the door controller 40. The door lock motor 70 is also electrically connected to the door lock 20. The door controller 40 is used to control the door lock motor 70 to drive the door lock 20 to enter or exit a locked state.

[0027] In some embodiments, the vehicle includes a main power supply 81 and an auxiliary power supply 82 connected to the door controller 40 and the door handle drive device 50. Both the main power supply 81 and the auxiliary power supply 82 can supply power to the door controller 40 and the door handle drive device 50. In addition, the main power supply 81 and the auxiliary power supply 82 are electrically connected to the control system 10 and can supply power to the control system 10. The main power supply 81 and the auxiliary power supply 82 are also electrically connected to the aforementioned collision sensor 30 and the door lock motor 70 to realize power supply.

[0028] Combination Figure 2 As shown, an embodiment of the application provides a vehicle control method, which is applied to the control system of the aforementioned vehicle, and the control method includes steps S11 to S13.

[0029] Step S11 , in response to a collision signal indicating that a vehicle collision occurs, controlling the door lock of the vehicle to remain in a mechanical release position.

[0030] The collision controller senses whether the vehicle has collided, generates and sends a sensing signal to the control system. When the collision sensor senses that the vehicle has collided, the sensing signal includes a collision signal. When the control system receives the collision signal, it indicates that the vehicle has collided, and the vehicle's door lock is automatically kept in the mechanical release position. The user can open the door lock by mechanical release. After the collision controller senses that the vehicle has collided, the process of sending a collision signal to the control system continues for a set period of time and ignores status feedback. This is conducive to improving the stability and continuity of the collision sensor sending the collision signal, and avoiding signal loss due to too short a sending time. The set time here is, for example, 4s.

[0031] Step S12, in response to the electric release request signal indicating the electric release of the door lock, controlling the door lock to enter the electric release position to perform the electric release of the door lock.

[0032] After the door lock is kept in the mechanical release position, if the control system receives an electric release request signal for instructing the electric release of the door lock, the current information transmission is normal and there is still power available for the electric release of the door lock. At this time, the electric release position is entered according to the user's needs, so that the user can release the door lock by electric release.

[0033] Step S13, after the electric release of the door lock is completed, the door lock is controlled to reset to the mechanical release position.

[0034] After the electric release is completed according to user requirements, the door lock is controlled to return to the mechanical release position and remain there.

[0035] By adopting the vehicle control method provided in the embodiment of the present application, when a collision signal indicating that the vehicle has collided is received, the door lock of the vehicle is automatically kept in the mechanical release position, so as to facilitate the user to perform the mechanical release operation. When an electric release request signal is received, the door lock is first electrically released, and then automatically reset to the mechanical release position after the electric release of the door lock is completed. In this way, after the vehicle collides, in addition to the electric release of the door lock according to the user's instructions, the door lock of the vehicle is kept in the mechanical release position, which is conducive to avoiding the situation that when the vehicle is powered on, the door lock of the vehicle is kept in the electric release position, resulting in the user being unable to mechanically release the door lock and thus causing the user to be trapped, which is conducive to improving the safety performance of the vehicle.

[0036] In some embodiments, the sensing signal includes a PWM (Pulse Width Modulation) signal and a CAN (Controller Area Network) signal, and the control method further includes: obtaining a PWM signal and a CAN signal. In response to a collision signal indicating that a vehicle has collided, controlling the door lock of the vehicle to remain in a mechanical release position includes: when a collision signal appears in either the PWM signal or the CAN signal, controlling the door lock of the vehicle to remain in a mechanical release position. In this way, the collision signal is sent in two ways, the PWM signal and the CAN signal, and the two ways are mutually backed up and redundant, which is conducive to avoiding the loss of collision signal transmission and improving the stability of collision signal transmission. Specifically, for the PWM signal, the collision controller sends a first PWM signal when the vehicle is in a normal state, and when the vehicle is in a collision state, the collision controller sends a second PWM signal different from the first PWM signal. When the control system receives the second PWM signal, it determines that the vehicle has collided. Accordingly, a specific CAN signal is set to distinguish the collision signal from other situations.

[0037] In some embodiments, the control method further includes: when no collision signal is received, controlling the vehicle's door lock to remain in the electric release position. The door lock has been in the electric release position. After the customer makes an unlocking request, the control system receives the customer's command and judges and then controls the forwarding. The customer can unlock and open the door through the internal and external electric opening buttons or the internal emergency handle. At this time, the vehicle's external opening handle cannot mechanically drive the door lock. This design can put the user in the scene of opening the door with electricity as much as possible, reduce mechanical operations, and improve customer comfort. It is equivalent to changing the default holding position of the vehicle door lock according to whether the collision signal is received. When the collision signal is received, the vehicle door lock is controlled to remain in the mechanical release position to ensure the reliability of the door lock switch under special circumstances, giving priority to safety performance. When the collision signal is not received, the vehicle door lock is controlled to remain in the electric release position to ensure the convenience of the door lock switch under normal driving conditions, giving priority to the comfort of the user. In this way, it can be adjusted according to different conditions of the vehicle to meet the actual needs of the user at the moment, which is conducive to optimizing the user experience.

[0038] In some embodiments, a vehicle includes a door controller, a door handle driving device, and an embedded door handle, wherein the door handle driving device is electrically connected to the door controller; the door controller is used to control the door handle driving device to drive the door handle to pop out. During normal driving of the vehicle, the embedded door handle is in an embedded position, at which time the door handle is hidden and the user cannot directly operate the door handle. After the door handle is driven by the door handle driving device, it opens to the deployed position, at which time the user can directly operate the door handle to open the vehicle door. Figure 3 As shown, the control method also includes steps S21 to S25.

[0039] Step S21, in response to the collision signal, sending an ejection instruction to the door controller to control the door handle driving device to drive the door handle to eject.

[0040] In some embodiments, sending a pop-up instruction to the door controller includes: sending a pop-up instruction to the door controller so that the door controller intermittently controls the door handle driving device to drive the door handle to pop out multiple times.

[0041] The sending of the pop-up instruction to the door controller includes: continuously sending the pop-up instruction to the door controller within a first duration, for example, continuously sending the pop-up instruction to the door controller for 10 seconds. This helps to reduce the risk of instruction loss and improve the reliability of instruction transmission.

[0042] After the door controller receives the pop-up instruction, it controls the door handle drive device to drive the door handle to pop out intermittently for multiple times. That is, after the door controller receives the pop-up instruction, it sends the pop-up drive instruction for driving the door handle to pop out to the door handle drive device intermittently for multiple times. Specifically, the pop-up drive instruction is continuously sent to the door handle drive device until the duration of continuously sending the pop-up drive instruction reaches the first duration. After the duration of stopping sending the pop-up drive instruction reaches the first intermittent duration, the pop-up drive instruction is continuously sent to the door handle drive device within the first duration, and the cycle is repeated multiple times. Exemplarily, the pop-up drive instruction is sent to the door handle drive device for 200ms each time, and an intermittent duration is set between every two continuous sending of the pop-up drive instruction. In this way, regularly controlling the door handle drive device to drive the door handle to pop out is conducive to avoiding faults caused by signal loss or interference, and ensuring that the door handle pops out normally. In addition, by setting the intermittent duration, the door handle drive device is prevented from being stuck due to too frequent instructions, which is conducive to improving the service life of the door handle and the door handle drive device and reducing power consumption.

[0043] Step S22, monitoring the current position of the door handle.

[0044] Step S23, determining whether the current position of the door handle is the set unfolding position.

[0045] The setting expansion position is a position where the user can directly perform manual operations.

[0046] If the current position of the door handle is the set unfolded position, execute step S24; if not, execute step S25.

[0047] Step S24, stop sending the eject instruction to the door controller.

[0048] Step S25, continue to send the pop-up instruction to the door controller.

[0049] Since the door handle cannot be directly operated by the user when it is embedded, after receiving the collision signal, a pop-up command is automatically sent to the door controller to drive the door handle to pop out, so that the user can open the door through the door handle. In addition, considering that the vehicle may be damaged after a collision, the embedded door handle may not be able to pop out normally due to problems such as damaged signal transmission, resulting in the door being unable to be opened normally. After sending the pop-up command to the door controller, the current position of the door handle is fed back in real time to determine the final execution effect of the door handle. Stopping sending the pop-up command to the door controller when the door handle is opened to the set deployment position helps reduce the risk of the door handle failing to pop out normally.

[0050] In some embodiments, when the current position of the door handle is not the set deployment position, the control method further includes: sending a self-driving signal for controlling the door handle driving device to drive the door handle to pop out. This is equivalent to setting a self-driving program for the door controller, so that when the control system fails to drive the door handle to pop out, the door controller automatically controls the door handle driving device to drive the door handle to deploy, which is conducive to further ensuring that the door handle pops out normally.

[0051] In some embodiments, the control method further includes: when sending a pop-up instruction to the door controller, sending a collision signal to the door controller, so that the door controller sends a self-driving signal for controlling the door handle driving device to drive the door handle to pop out when the pop-up instruction is not received and the current position of the door handle is not the set deployment position. That is, after the control system receives the collision signal, the pop-up instruction and the collision signal are sent to the door controller. If the door controller does not receive the pop-up instruction and the current position of the door handle is not the deployment position, the self-driving signal is directly sent to drive the door handle to pop out, which is conducive to ensuring that the door handle pops out normally, so that it is convenient for the user to open the door through the door handle.

[0052] In some embodiments, the vehicle further includes a main power supply and an auxiliary power supply connected to the door controller and the door handle drive, and the main power supply is used to power the door controller and the door handle drive. Specifically, both the main power supply and the auxiliary power supply are connected to the door controller and the door handle drive. During normal use of the vehicle, the door controller and the door handle drive are connected via the main power supply, and the auxiliary power supply is in a dormant or shutdown state. The control method further includes: in response to a collision signal, controlling the main power supply to power the door controller and the door handle drive; when the power of the main power supply is lower than the set power, controlling the auxiliary power supply to power the door controller and the door handle drive. In this way, the risk of the door controller and the door handle drive failing to function normally due to power feeding after a collision can be avoided, which is conducive to improving the reliability of the vehicle door lock switch control.

[0053] In some embodiments, the vehicle includes a door controller and a door lock motor, and the door controller and the door lock are both electrically connected to the door lock motor; the door controller is used to control the door lock motor to drive the door lock. Figure 4 As shown, the control method also includes steps S31 to S35.

[0054] Step S31, in response to the collision signal, sending an unlocking instruction to the door controller to drive the door lock to exit the locked state through the door lock motor.

[0055] In some embodiments, sending an unlock command to the door controller includes sending an unlock command to the door controller so that the door controller intermittently controls the door lock motor to drive the door lock to exit the locked state.

[0056] Specifically, the unlocking instruction is continuously sent to the door controller within the second duration.

[0057] After the door controller receives the unlock instruction, it controls the door lock motor to drive the door lock to exit the locked state intermittently and multiple times. That is, after the door controller receives the unlock instruction, it sends the unlock drive instruction for driving the door lock to unlock to the door lock motor intermittently and multiple times. More specifically, the unlock drive instruction is continuously sent to the door lock motor until the duration of continuously sending the unlock drive instruction reaches the second duration. When the duration of stopping sending the unlock drive instruction reaches the second intermittent duration, the unlock drive instruction is continuously sent to the door lock motor within the second duration. Repeat multiple times. Exemplarily, the door lock motor is driven to make the door lock exit the locked state for 200ms, and after pausing for 1s, the door lock motor is driven for 200ms. In this way, it is helpful to reduce the risk that the door lock cannot be unlocked normally and to improve the reliability of unlocking the door lock. At the same time, the intermittent duration is set to avoid the door lock motor from getting stuck due to receiving the unlock drive instruction too frequently, which is helpful to ensure the life of the door lock motor.

[0058] Step S32, monitoring the current state of the door lock.

[0059] In some embodiments, when the duration that the door controller controls the door lock motor to drive the door lock to exit the locked state reaches a third duration, the current state of the door lock is monitored. Specifically, when the duration that the door controller sends the unlocking drive instruction to the door lock motor reaches the third duration, the current state of the door lock is monitored again. When the duration does not reach the third duration, the current state of the door lock is not monitored. This can save the monitoring and subsequent judgment process, which is conducive to saving computing power and energy consumption. Exemplarily, since the process of the door controller sending the unlocking drive instruction is cyclical. The third duration can be determined according to the cycle period, for example, the duration of three cycles is used as the third duration. That is, after the door controller sends the unlocking drive instruction to the door lock motor three times in a cycle, the current state of the door lock is monitored.

[0060] Step S33, determining whether the current state of the door lock is a locked state.

[0061] If the current state of the door lock is the locked state, execute step S34; if the current state of the door lock is not the locked state, execute step S35.

[0062] Step S34, continue to send an unlocking instruction to the door controller.

[0063] Step S35, stop sending unlocking instructions to the door controller.

[0064] During normal driving of the vehicle, in order to prevent users from accidentally opening the door, the door lock is generally locked by default and needs to be unlocked before it can be unlocked. Receiving a collision signal means that the vehicle has collided. At this time, in order to facilitate the user to open the door, an unlock command is automatically sent to the door controller to drive the door lock out of the locked state. Further considering that the collision process may cause damage to the vehicle, after sending the unlock command to the door controller, the status of the door lock is monitored and the unlocking effect of the door lock is fed back in real time. And if the door lock is not unlocked normally, continue to send the unlock command to the door controller to continue to push the door lock to unlock. This helps to reduce the risk of the door lock failing to unlock normally and causing the user to be unable to open the door.

[0065] After the control system sends the above-mentioned pop-up instruction and / or unlocking instruction to the door control, if the control system restarts due to voltage drop, it will automatically return to the original running process after restarting and continue to send the pop-up instruction and / or unlocking instruction sent before restarting.

[0066] Combination Figure 5 As shown, a further complete example is given here to illustrate the vehicle control method. The control method includes steps S401 to S427.

[0067] Step S401 : The collision sensor senses whether the vehicle collides, and generates a collision signal when the vehicle collides.

[0068] Step S411: the control system controls the door lock of the vehicle to remain in a mechanical release position in response to the collision signal.

[0069] Step S412, the control system controls the door lock to enter the electric release position in response to the electric release request signal indicating the electric release of the door lock, so as to electrically release the door lock.

[0070] Step S413, after the electric release of the door lock is completed, the control system controls the door lock to reset to the mechanical release position.

[0071] Step S421: the control system sends an unlocking instruction to the door controller in response to the collision signal.

[0072] Step S422: The control system monitors the current state of the door lock, which includes a locked state and an unlocked state.

[0073] Step S423: The control system determines whether the current state of the door lock is a locked state.

[0074] If yes, continue to execute step S421; if no, execute step S424.

[0075] Step S424: the control system stops sending unlocking instructions to the door controller.

[0076] Step S425: the control system sends a pop-up instruction to the door controller to control the door handle driving device to drive the door handle to pop out.

[0077] Step S426: The control system determines whether the current position of the door handle is the set deployment position.

[0078] If yes, execute step S427; if no, continue to execute step S424.

[0079] Step S427, the control system stops sending the eject instruction to the door controller.
