[0001] The present application relates to the field of winch control of new energy vehicles, in particular to a new energy vehicle electric winch control method and system. BACKGROUND

[0002] The winch of the vehicle is a functional configuration on the off-road vehicle, which is very important for field rescue. With the off-road vehicle gradually entering people's field of vision, the electric winch is an important part in the process of vehicle escape and vehicle rescue, and the control of the winch becomes particularly important. The winch has gradually been miniaturized and motorized, and the winch can be controlled by an electric method to achieve the purpose of rescue. For example, a kind of electric winch used on a vehicle in patent application No. 201410327095.8, the electric winch comprises a motor, a mounting frame and a winding drum, the winding drum is rotatably installed on the mounting frame, characterized in that the motor is installed on one side of the mounting frame, a gear box is installed on the other side of the mounting frame, the main shaft of the motor is connected with one end of a transmission shaft, the other end of the transmission shaft is arranged in the gear box, the middle section of the transmission shaft is located in the inner hole of the winding drum, and a fixed inner tooth ring is arranged in the gear box. The forward and reverse movement of the winch is realized by controlling the forward and reverse rotation of the motor, thereby achieving the purpose of rescue.

[0003] In the prior art, the electric winch is loaded on the vehicle, and the winch control is generally arranged on the winch or has a separate remote controller. The operation on the winch is inconvenient and has safety risks, the remote controller is easy to lose, causing customer complaints, resulting in that the winch cannot be used, and manual control also has certain experience deficiency, causing damage to the winch or the corresponding traction rope of the winch. SUMMARY

[0004] The present application aims to overcome the deficiencies of the prior art, and provides a new energy vehicle electric winch control method and system. The work of the winch is controlled by a soft switch built in an IHU and / or an automatic execution configuration, thereby realizing reliable operation of the winch control, improving the use experience of the electric winch, and reducing customer complaints.

[0005] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows: a new energy vehicle electric winch control system, the system comprises an IHU soft switch, an IHU host and a winch controller; the signal of the IHU soft switch is sent to the IHU host, the IHU host and the winch controller are connected through CAN communication; the winch controller drives the forward and reverse rotation of the electric winch based on the control signal sent by the IHU host; the IHU soft switch is used to record the manual control signal of the user to the winch.

[0006] The winch controller is connected to a vehicle status sensor, which is used to detect the current vehicle status. The winch controller controls the operation of the electric winch based on the current vehicle status and the control signal received from the IHU host.

[0007] The control system also includes a torque sensor, which is used to collect the torque of the electric winch during its operation. Its output is connected to the winch controller, which adjusts the operating state of the electric winch based on the torque information.

[0008] After receiving the automatic control command from the IHU host, the winch controller uses automatic control to control the operation of the electric winch.

[0009] The winch controller is connected to the vehicle alarm, and the winch controller drives the vehicle alarm to issue a corresponding alarm reminder signal based on the working status of the winch.

[0010] A control method for a new energy vehicle electric winch control system includes: a user triggers the winch function via an IHU soft switch; the IHU host monitors in real time the triggering of the forward or reverse button on the IHU soft switch and feeds back the corresponding signal to the winch controller via CAN communication; after receiving the forward or reverse signal, the winch controller determines whether the current vehicle status meets the working requirements of the electric winch; if so, it controls the electric winch to rotate forward or reverse to execute the corresponding forward or reverse signal.

[0011] During the forward and reverse rotation of the electric winch, the torque signal during the winch's operation is monitored in real time. The working status of the electric winch is determined based on the torque signal, and the vehicle-mounted alarm is controlled to issue a corresponding torque working status alarm reminder signal based on the working status.

[0012] The IHU main unit sends the corresponding forward and reverse commands to the winch controller only after the forward and reverse buttons of the IHU soft switch have been triggered for a set time. Once the forward and reverse switches of the IHU soft switch have been deactivated, the corresponding stop signal is immediately sent to the winch controller.

[0013] After receiving the forward and reverse rotation commands from the IHU host, the winch controller controls the winch to run at the set speed until the torque reaches the set threshold.

[0014] The user triggers the electric winch's automatic mode via the IHU soft switch. The IHU host sends the corresponding automatic mode command to the winch controller. After receiving the automatic control command, the winch controller automatically controls the electric winch and displays the automatic working status in real time through the vehicle alarm.

[0015] The advantages of this invention are as follows: It controls the winch's operation through a soft switch built into the IHU and / or by configuring automatic execution, thereby achieving reliable winch control, improving the user experience of the electric winch, and reducing customer complaints. It is compatible with both manual and automatic control modes, further enhancing the control experience of the electric winch, while the automatic control logic is more rational and reliable. During winch control, torque is monitored in real time to achieve safety monitoring; in case of abnormal torque, an alarm signal is directly issued through the vehicle's instrument panel, providing timely alerts for abnormalities. Attached Figure Description

[0016] The following is a brief explanation of the contents of each of the accompanying drawings and the markings in the drawings:

[0017] Figure 1 This is a flowchart of the control method for the electric winch of the present invention;

[0018] Figure 2 This is a structural block diagram of the control system of the electric winch of the present invention. Detailed Implementation

[0019] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0020] The high-voltage electric winch control method for new energy vehicles provided in this embodiment includes two modes: manual control mode and automatic control mode. This allows users to manually and automatically control the electric winch, improving the user experience. At the same time, it can monitor the working status of the electric winch in real time, improving the reliability and safety of the winch during operation, and has an automatic alarm function.

[0021] This solution discloses a novel control strategy for high-voltage electric winches in new energy vehicles, belonging to the automotive field, and specifically includes the following steps:

[0022] 1. Add a soft switch to the I HU. The soft switch triggers the CAN signal network to the winch controller. The length of the switch contact time controls the length of time the winch cable is wound and unwound.

[0023] 2. The winch controller determines the internal strategy based on the current vehicle status and the received instructions, and controls the motor control circuit to achieve forward and reverse rotation of the winch by switching the relay on and off. At the same time, it receives the internal torque and long / short signals from the winch.

[0024] 3. The winch controller identifies the current status based on the torque and status information fed back by the winch, and determines whether an alarm message needs to be fed back. In case of an abnormal situation, the winch controller sends an alarm message to the instrument to remind the driver that the current situation is abnormal and to stop operation immediately.

[0025] 4. Control process of the system: Based on the current driving mode of the vehicle, the system matches the signal interaction communication to quickly realize the control of the electric winch and improve the driving experience;

[0026] The beneficial effects of adopting this technical solution are: it effectively improves the convenience of winch operation, enhances the driver's user experience, reduces unnecessary safety hazards during winch operation, and establishes a positive market reputation. The solution is further described in detail below with reference to the accompanying drawings:

[0027] like Figure 2 The diagram shown is a structural schematic of a new energy vehicle electric winch control system in this embodiment. The new energy vehicle electric winch control system of this solution includes an IHU soft switch, an IHU main unit, and a winch controller. The signal from the IHU soft switch is sent to the IHU main unit, and the IHU main unit and the winch controller are connected via CAN communication. The winch controller drives the electric winch to operate in both forward and reverse directions based on the control signal sent by the IHU main unit. The IHU soft switch is used to input the user's manual control signal for the winch.

[0028] The IHU soft switch is implemented in the touch screen of the IHU host through software development. Users can touch the soft switch to trigger it. The trigger control signal of the IHU soft switch is received by the IHU host after passing through the display screen. Then, the IHU host sends the corresponding control signal to the winch controller via the CAN network. After receiving the control signal, the winch controller drives the motor in the electric winch to rotate forward and backward to achieve the purpose of manually controlling the operation of the winch.

[0029] The IHU soft switch includes a forward switch, a reverse switch, and / or a start switch. The start switch is used to activate the function. The forward and reverse switches are used to input user operation signals. When the user triggers the forward switch and continues to trigger it, the IHU host receives the signal and then sends a forward command to the winch controller. Similarly, when the user triggers the reverse switch and continues to trigger it, the IHU host receives the signal and then sends a reverse command to the winch controller, thus realizing manual forward and reverse control of the winch. After the forward and reverse rotations are completed, the function can be turned off using the start switch.

[0030] In this embodiment, the winch controller is connected to a vehicle status sensor, which detects the current vehicle status. The winch controller controls the operation of the electric winch based on the current vehicle status and the control signals received from the IHU host. The vehicle status sensor collects the high-voltage status of the new energy vehicle. Because the electric winch requires power to operate, it must be in a high-voltage state before it can start working. Therefore, when the winch controller sends a control signal to the electric winch, it needs to detect the current vehicle status. When the vehicle is in a high-voltage state, the winch controller sends corresponding forward and reverse commands to the electric winch motor to control the electric winch to operate. Otherwise, the winch controller connects to the instrument panel or IHU host via a CAN network, and the instrument panel or IHU host displays the current winch unavailable status and sends a corresponding reminder signal to the user.

[0031] In this solution, the control system also includes a torque sensor. This sensor collects the torque of the electric winch during operation, and its output is connected to the winch controller. The winch controller adjusts the winch's operation based on this torque information. When the winch is working, it rotates to pull the stranded vehicle by driving the cable. The torque generated by this rotation represents the pulling force of the cable. When the torque reaches a certain level, safety hazards arise, such as the rope breaking or damage to the winch's mechanical components or motor. Therefore, torque is limited. Specifically, a torque threshold is set in the winch controller. When the torque exceeds the set threshold during winch operation, the controller stops the electric winch or, after a delay, stops operation and issues an alarm signal via the vehicle's instrument panel or other onboard alarms. The alarm signal primarily indicates an abnormal torque and a potential safety risk, serving as a reminder to suspend operation to prevent accidents. The vehicle alarm uses the vehicle instrument panel or vehicle IHU display screen to issue corresponding reminders. The winch controller is connected to the vehicle alarm and drives the vehicle alarm to issue corresponding alarm reminder signals based on the working status of the winch, which is convenient for alarming abnormal torque during operation and reminding to stop working.

[0032] In a preferred embodiment of this application, an automatic control mode for the winch is provided, which automatically controls the winch to meet rescue needs. Specifically, an automatic mode activation and deactivation soft switch is developed within the IHU soft switch. Activation and deactivation of the automatic mode are triggered by the soft switch. After the soft switch is triggered, the IHU host receives the trigger signal and sends a corresponding signal to the winch controller via CAN communication. Upon receiving the automatic control command from the IHU host, the winch controller automatically controls the operation of the electric winch.

[0033] The automatic control method includes: after receiving an automatic control mode command, the winch controller outputs a control signal to the electric winch, controlling the electric winch to rotate clockwise in a manner that is initially fast, then slows down, and finally reduces the speed to a very small or even zero speed. The speed is correlated with the collected torque of the electric winch. When the detected torque gradually increases to the torque threshold corresponding to cable straightening, the speed gradually decreases from the initial speed to a very small or even zero speed, and then maintains this speed while simultaneously increasing the torque to rescue the stranded vehicle. The relationship between the initial speed, the rate of speed reduction, and the torque is pre-calibrated. The purpose of this is that when rescuing a stranded vehicle using an electric winch, the cable is initially loose. As the electric winch rotates clockwise, the cable gradually straightens until it becomes taut, at which point it begins to stretch the stranded vehicle, attempting to lift it and achieve rescue. To quickly achieve the transition from loose to taut cable, reduce rescue time, and avoid the safety hazard of sudden cable tautness caused by a consistently high speed, the speed is set to initially be fast, then slow down, and then, after detecting the torque corresponding to cable straightening and tautness, the speed is reduced to a very small or even zero speed before increasing the torque to achieve rescue. Here, rotational speed refers to the rotational speed of the motor in the electric winch. Since the motor rotation drives the winch to rotate, which in turn pulls the cable for rescue, the rotation and rotational speed can be characterized by collecting the motor's rotational speed.

[0034] This embodiment also provides a control method for an electric winch in a new energy vehicle. The method includes: a user triggers the winch function via an IHU soft switch; the IHU host monitors the user's operation of the forward or reverse button on the IHU soft switch and feeds back the corresponding signal to the winch controller via CAN communication. Upon receiving the forward / reverse signal, the winch controller determines whether the current vehicle status meets the requirements for the electric winch's operation. If so, it controls the electric winch to rotate forward or reverse to execute the corresponding forward / reverse signal. When the user triggers the forward switch and continues to do so, the IHU host receives the signal and sends a forward command to the winch controller. Similarly, when the user triggers the reverse switch and continues to do so, the IHU host receives the signal and sends a reverse command to the winch controller. Upon receiving the forward / reverse command, the winch controller collects the current vehicle status. If the vehicle is under high-voltage conditions, the winch controller outputs the corresponding forward / reverse command to the electric winch; otherwise, the winch controller connects to the instrument cluster or IHU host via a CAN network, displays the current winch unavailable status on the instrument cluster or IHU host, and sends a corresponding reminder signal to the user. The purpose of this is because electric winches require high-voltage power to operate. Therefore, the vehicle needs to be in a high-voltage state to provide power to the electric winch, thus enabling it to work. Therefore, when sending a control signal to the electric winch, it is necessary to check whether the vehicle's current state meets the requirements. If not, a corresponding reminder signal needs to be sent to remind the user that the current state does not meet the requirements for the electric winch to work, and to remind the user to perform the corresponding operation, such as switching the vehicle to a high-voltage state.

[0035] During the forward and reverse rotation of the electric winch, the torque signal is monitored in real time. Based on this torque signal, the operating status of the electric winch is determined, and the vehicle-mounted alarm is activated to issue a corresponding torque-related alarm signal. A torque threshold is set in the winch controller. When the torque exceeds the set threshold during winch operation, the controller stops the electric winch or, after a delay, stops operation and issues an alarm signal via the vehicle's instrument panel or other onboard alarm. This alarm primarily indicates an abnormal torque and a potential safety risk, prompting a suspension of operation to prevent accidents. The vehicle-mounted alarm uses the vehicle's instrument panel or IHU display screen to issue the corresponding warning.

[0036] In a preferred embodiment, during the operation of the electric winch, if the real-time torque value is detected to be greater than a set threshold, a corresponding alarm signal is immediately issued to remind the user that the torque generated for rescue has reached the maximum threshold. Furthermore, if the torque is still greater than the maximum threshold after a timer of t seconds has been started after reaching the maximum torque, the electric winch is stopped, and a corresponding stop-work reminder is issued. This is done because reaching the maximum torque may pose a risk of damage to the winch and cables, thus requiring a warning. The purpose of continuing operation for t seconds after reaching the maximum torque threshold is to attempt a successful rescue at that torque. If rescue is still unsuccessful after reaching the maximum torque for t seconds, it indicates that the vehicle's electric winch cannot rescue the trapped vehicle, and there is no need to continue operating the electric winch at maximum torque at the risk of damage. In this case, a corresponding reminder signal is issued via the vehicle's instrument panel, and the electric winch stops operating. When the electric winch stops operating, it is first controlled to rotate in the opposite direction at a low speed while the torque is monitored in real time. The electric winch stops operating only when the torque decreases to a set value.

[0037] In a preferred embodiment, the IHU (Induction Hull) host sends the corresponding forward / reverse commands to the winch controller only after the forward and reverse buttons of the IHU soft switch have been triggered for a set time. Immediately after the forward and reverse switches of the IHU soft switch are deactivated, a corresponding stop signal is sent to the winch controller. This is to avoid false triggering caused by brief activation of the forward and reverse switches of the IHU soft switch. Only after the forward and reverse soft switches are pressed and held for a certain period will the corresponding commands be sent to the winch controller, thus avoiding safety hazards caused by false triggering. When starting forward or reverse rotation, the forward or reverse soft switch is pressed and held. The IHU will only send the forward / reverse commands to the winch controller after the soft switch has been held for a certain period. The command must be held down for it to be effective. Once the corresponding soft switch for forward or reverse rotation is deactivated and the soft switch is released, the IHU detects this state and immediately stops sending the corresponding control commands. The winch controller, upon ceasing to receive forward and reverse commands, immediately stops the operation of the electric winch.

[0038] When controlling the electric winch via the IHU soft switch, to avoid safety hazards caused by the winch rotating too fast or taking too long due to its slow rotation, this application pre-sets the rotation speed. After receiving the forward and reverse rotation commands from the IHU host, the winch controller controls the winch to run at the set speed until the torque reaches the set threshold. Because the cable is initially loose during rescue operations, the torque is low. At this time, controlling the electric winch to rotate at the set speed quickly straightens the rescue cable, increasing the torque. When the torque reaches the set threshold, it indicates that the cable has been straightened, so the rotation speed must be reduced to a minimum, or even zero. At this point, the main purpose is to increase the torque to enhance the rescue effort. Therefore, after rotating at the set speed to reach the set torque, the speed of the electric winch is reduced to the set minimum speed or close to zero, which increases the torque and achieves the rescue objective.

[0039] In a preferred embodiment of this application, the user triggers the automatic mode of the electric winch via an IHU soft switch. The IHU host sends the command corresponding to the automatic mode to the winch controller. Upon receiving the automatic control command, the winch controller automatically controls the electric winch and displays the automatic operating status in real time through a vehicle alarm. An automatic mode soft switch is provided in the IHU soft switch. After the automatic mode soft switch is triggered, the IHU host receives the trigger and sends an automatic control mode signal to the winch controller via a CAN signal. Upon receiving the automatic control mode signal, the winch controller enters the automatic control mode. In the automatic control mode, the operation of the electric winch is controlled by an automatic control strategy, which includes:

[0040] After receiving the automatic control mode command, the winch controller outputs a control signal to the electric winch, controlling it to rotate clockwise in a manner that initially increases speed, then decreases to a very low speed or even zero. The speed is correlated with the measured torque of the electric winch. When the detected torque gradually increases to the torque threshold required for cable straightening, the speed gradually decreases from the initial speed to a very low speed or even zero, and then maintains this speed while simultaneously increasing torque to rescue the stranded vehicle. The relationship between the initial speed, the rate of speed reduction, and the torque is pre-calibrated. This is done so that when rescuing a stranded vehicle with the electric winch, the cable is initially loose. As the winch rotates clockwise, the cable gradually straightens until it becomes taut, at which point it begins to pull the stranded vehicle up, attempting to lift it. To quickly achieve the transition from loose to taut cable, reducing rescue time and avoiding the safety hazard of sudden cable tautness caused by a consistently high speed, the speed is initially set to increase quickly, then decrease to a very low speed or even zero after detecting the torque corresponding to cable straightening and tautness, before increasing torque to achieve the rescue. Here, rotational speed refers to the rotational speed of the motor in the electric winch. Since the motor rotation drives the winch to rotate, which in turn pulls the cable for rescue, the rotation and rotational speed can be characterized by collecting the motor's rotational speed.

[0041] After detecting that the torque has reached the level required for cable tautness, the torque and speed of the electric winch are monitored in real time. When a sudden decrease in torque and an increase in speed are detected, the rescue is considered successful. At this point, the winch controller stops the electric winch from rotating forward and sends a reminder signal through the vehicle instrument panel or IHU host. Simultaneously, it collects soft-switching signals in real time. When the soft-switching signal indicating that the electric winch has stopped working is received, the winch controller drives the electric winch to reverse, thereby retrieving the cable. The number of reverse rotations is the same as the forward rotation. The forward rotation data can be calculated by collecting the number of rotations of the electric winch through an encoder. At the end, the electric winch is controlled to reverse according to the forward rotation data, thereby achieving the purpose of ending the electric winch function and retrieving the cable.

[0042] If, during real-time monitoring of the electric winch's torque and speed, the torque is detected to exceed the set maximum safe torque threshold, a corresponding alarm signal will be immediately issued to remind the user that the torque generated for rescue has reached the maximum threshold. Furthermore, if the torque still exceeds the maximum threshold after a timer of t seconds, the electric winch will stop working, and a corresponding stop-work reminder will be issued. This is done because reaching the maximum torque may pose a risk of damage to the winch and cables, hence the need for a warning. The purpose of continuing operation for t seconds after reaching the maximum torque threshold is to attempt a successful rescue at that torque. If rescue is still unsuccessful after t seconds at the maximum torque, it indicates that the vehicle's electric winch is incapable of rescuing the trapped vehicle, and there is no need to continue operating the electric winch at maximum torque, risking damage. In this case, a corresponding reminder signal will be issued via the vehicle's instrument panel, and the electric winch will stop working. When the electric winch stops working, it will first be controlled to rotate in the opposite direction at a low speed while the torque is monitored in real time. The electric winch will stop working only when the torque decreases to the set value.

[0043] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
