Moreover, winches have gradually been miniaturized and electrified, and the winches can be controlled electrically to achieve the purpose of rescue. For example, the patent application number is 201410327095.8, which is an electric winch for automobiles. The electric winch includes a motor, a mounting frame and a winding drum, and the winding drum is rotatably mounted on the mounting frame. It is characterized in that the motor is mounted on one side of the mounting frame, and a gear box is mounted on the other side of the mounting frame. The main shaft of the motor is connected to one end of the transmission shaft, and 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 gear ring is arranged in the gear box. The forward and reverse movement of the winch is achieved by controlling the forward and reverse rotation of the motor, thereby achieving the purpose of rescue.

[0003] In the prior art, an electric winch is mounted on a vehicle, and the winch control is generally arranged on the winch or has a separate remote control. Arranging it on the winch is inconvenient to operate and also poses a safety risk. The remote control is easy to be lost, causing customer complaints, resulting in the winch being unusable. In addition, there is a certain lack of experience in manual control, which may cause damage to the winch or the corresponding traction rope on the winch. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a new energy vehicle electric winch control method and system, which controls the operation of the winch by a soft switch built into the IHU and / or configuring automatic execution, thereby achieving reliable operation of the winch control, improving the user experience of the electric winch, and reducing customer complaints.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a new energy vehicle electric winch control system, the system includes an I HU soft switch, an I HU host, and a winch controller; wherein the signal of the I HU soft switch is sent to the I HU host, and the I HU host and the winch controller are connected via CAN communication; the winch controller drives the forward and reverse operation of the electric winch based on the control signal sent by the I HU host; the I HU soft switch is used to record the user's manual control signal of the winch.

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

[0007] The control system further includes a torque sensor, which is used to collect the torque of the electric winch in a working state, and an output end of the torque sensor is connected to a winch controller, and the winch controller adjusts the working state of the electric winch based on the torque information.

It immediately sends the corresponding stop working signal to the winch controller after the forward and reverse switches of the I HU soft switch are released.

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

[0019] The specific implementation of the present invention will be further explained in detail below by describing the optimal embodiment with reference to the accompanying drawings.

[0020] The present embodiment provides a method for controlling a high-voltage electric winch for a new energy vehicle, which includes a manual control mode and an automatic control mode. The method provides users with the ability to manually and automatically control the operation of the electric winch, thereby improving the user experience of the electric winch. At the same time, the working status of the electric winch can be monitored in real time, thereby improving the reliability and safety of the winch during operation, and the method has an automatic alarm function.

[0021] This scheme discloses a new type of new energy vehicle high-voltage electric winch control strategy, which belongs to the automotive field and specifically includes the following steps

[0022] 1. I HU adds a soft switch, which is triggered by the soft switch. The CAN signal network is transmitted to the winch controller, and the length of time the winch cable is retracted and released is controlled by the length of time the switch is in contact;

[0023] 2. The winch controller makes internal strategy decisions based on the current vehicle status and the received instructions, controls the motor control circuit by opening and closing the relay to realize the forward and reverse rotation of the winch, and receives the internal torque and length signal fed back by the winch;

[0024] 3. The winch controller identifies the current state based on the torque and state information fed back by the winch, and confirms whether alarm information needs to be fed back. In case of abnormal conditions, the winch controller feeds back alarm information to the instrument to remind the driver that the current state is abnormal and to stop the operation immediately;

[0025] 4. The control process of the system: According to the current driving mode of the vehicle, the signal interactive communication is matched to quickly realize the control of the electric winch and improve the driving experience;

[0026] The beneficial effects achieved by adopting the product of this technical solution are: it can effectively improve the convenience of winch operation, improve the driver's experience, reduce unnecessary safety hazards during winch operation, and establish market reputation. The following is a further detailed description of this solution in conjunction with the attached drawings as follows:

[0027] like Figure 2 As shown, it is a structural principle diagram of an electric winch control system for a new energy vehicle in this embodiment. The electric winch control system for a new energy vehicle in this scheme includes an IHU soft switch, an IHU host, and a winch controller; the signal of the IHU soft switch is sent to the IHU host, and the IHU host and the winch controller are connected via CAN communication; the winch controller drives the forward and reverse operation of the electric winch based on the control signal sent by the IHU host; the IHU soft switch is used to record the user's manual control signal of the winch.

[0028] The I HU soft switch is implemented in the touch screen of the I HU host through software development. The user touches the soft switch through the touch screen to realize the trigger control of the soft switch. The trigger control signal of the I HU soft switch is received by the I HU host after passing through the display screen, and then the I HU host sends the corresponding control signal to the winch controller through the CAN network. After receiving the control signal, the winch controller drives the motor in the electric winch to rotate forward and reverse to realize the forward and reverse rotation of the electric winch, thereby achieving the purpose of manually controlling the work of the winch.

[0029] The I HU soft switch includes a forward switch, a reverse switch and a start switch. The start switch is used to start the function. The forward switch and the reverse switch are used to record the user's operation signal. When the user triggers the forward switch and continues to trigger the forward switch, the I HU host receives the signal, and then the I HU host sends the forward instruction to the capstan controller. Similarly, when the user triggers the reverse switch and continues to trigger the reverse switch, the I HU host receives the signal, and then the I HU host sends the reverse instruction to the capstan controller, thereby realizing manual forward and reverse control of the capstan. When the forward and reverse rotations are completed, the function can be turned off by the start switch.

[0030] In this embodiment, the winch controller is connected to the vehicle status sensor, and the vehicle status sensor 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 I HU host. The vehicle status sensor is used to collect the upper high voltage state of the new energy vehicle. Because the electric winch needs to be powered before it can work, it is required that the new energy vehicle is in the upper high voltage state before it can start working. Therefore, when the winch controller sends a control signal to the electric winch, it is necessary to detect the current state of the vehicle. When the vehicle is in a high voltage state, the winch controller sends the corresponding forward and reverse instructions to the motor of the electric winch to control the operation of the electric winch. Otherwise, the winch controller is connected to the instrument or I HU host through the CAN network, and the current winch unavailable state is displayed through the instrument or I HU host, and a corresponding reminder signal is sent to the user.

[0031] In this solution, the control system is also provided with a torque sensor, which is used to collect the torque of the electric winch in the working state. Its output end is connected to the winch controller, and the winch controller adjusts the working state of the electric winch based on the torque information. When the winch is working, it drives the cable to pull the trapped vehicle by rotating the winch. The torque generated by its rotation represents the state of pulling the trapped vehicle by the cable. When the torque reaches a certain level, it will cause safety hazards, such as the rope being broken or the mechanical mechanism or motor in the electric winch being damaged, so the torque is limited. That is, a torque threshold is set in the winch controller. When it is detected that the torque is greater than the set torque threshold when the winch is working, the winch controller drives the electric winch to stop or stop working after a delay and sends an alarm signal through the vehicle-mounted alarm such as the vehicle-mounted instrument. The alarm signal mainly indicates that there is a safety risk due to abnormal torque and suspends work to avoid safety accidents. The vehicle-mounted alarm uses the vehicle-mounted instrument or the vehicle-mounted IHU display screen to issue corresponding reminders. The winch controller is connected to the vehicle-mounted alarm. The winch controller drives the vehicle-mounted alarm to issue corresponding alarm reminder signals based on the working status of the winch, which is convenient for alarming abnormal torque during work and reminding to stop working.

[0032] In a preferred embodiment of the present application, the present application is provided with an automatic control mode of the winch, and the winch is automatically controlled in the automatic control mode to meet the rescue needs. In the IHU soft switch, a corresponding soft switch for opening and closing the automatic mode is developed and set, and the start and close of the automatic mode are triggered by opening and closing the automatic mode soft switch. After the soft switch is triggered, the IHU host receives the trigger signal and sends a corresponding signal to the winch controller through CAN communication. After the winch controller receives the automatic control instruction sent by the IHU host, the winch controller uses automatic control to control the operation of the electric winch.

[0033] The automatic control method includes: after receiving the automatic control mode instruction, the winch controller outputs a control signal to the electric winch, controls the electric winch to rotate forward in a manner that the speed is first fast and then slow and finally the speed is reduced to a small speed or even 0, the speed is related to the torque of the collected electric winch, when the detected torque gradually increases to the torque threshold when the cable is straightened, the speed is gradually reduced from the initial speed to a small speed or even 0 speed, and then the torque is increased at the same time to achieve the rescue of the trapped vehicle. Here, the initial speed and the speed of speed reduction are calibrated and designed in advance. The purpose of this is that when the electric winch is used to rescue the trapped vehicle, when the cable is in a loose state at the beginning, as the electric winch rotates forward, the cable is gradually straightened until it is tightened and begins to stretch the trapped vehicle, thereby trying to pull up the vehicle to achieve rescue. In this process, in order to quickly realize the cable from loose to tight, reduce the rescue time and avoid the safety hazards caused by the sudden tightening of the cable when the speed is always very fast, the speed is set here first fast and then slow, and then after detecting the torque corresponding to the straightening and tightening of the cable, the speed is reduced to a very small speed or even 0, and then the torque is increased to achieve rescue. The speed here refers to the speed of the motor in the electric winch. Because the rotation of the motor drives the winch to rotate and then pulls the cable for rescue, the rotation and speed can be characterized by collecting the speed of the motor.

[0034] This embodiment also provides a control method for an electric winch of a new energy vehicle, the method comprising: a user triggers the start of a winch function through an IHU soft switch, and then the IHU host monitors the triggering of the forward or reverse button in the IHU soft switch operated by the user in real time and feeds back the corresponding signal to the winch controller via the CAN communication method, and the winch controller determines whether the current vehicle state meets the working requirements of the electric winch after receiving the forward and reverse signals, and if so, controls the electric winch to rotate forward or reverse to execute the corresponding forward and reverse signals. When the user triggers the forward switch and continuously triggers the forward switch, the IHU host receives the signal, and then the IHU host sends the forward command to the winch controller. Similarly, when the user triggers the reverse switch and continuously triggers the reverse switch, the IHU host receives the signal, and then the IHU host sends the reverse command to the winch controller. After receiving the forward and reverse commands, the winch controller collects the current vehicle state. If the vehicle is in a high-voltage state, the winch controller outputs the corresponding forward and reverse commands to the electric winch, otherwise the winch controller is connected to the instrument or the IHU host through the CAN network, and the current winch unavailable state is displayed through the instrument or the IHU host, and a corresponding reminder signal is sent to the user. The purpose of doing this is because the electric winch requires high-voltage power supply to work, so the vehicle needs to be in a high-voltage state to provide power to the electric winch, thereby realizing the operation of the electric winch. Therefore, when sending a control signal to the electric winch, it is necessary to detect whether the vehicle state at this time is met. If not, it is necessary to send a corresponding reminder signal to remind the user that the current state does not meet the working state of the electric winch, and remind the user to perform corresponding operations, such as switching the vehicle into a high-voltage state.

[0035] During the forward and reverse rotation of the electric winch, the torque signal of the winch is monitored in real time, the working state of the electric winch is judged based on the torque signal, and the vehicle-mounted alarm is controlled to send a corresponding torque working state alarm reminder signal based on the working state. A torque threshold is set in the winch controller. When it is detected that the torque is greater than the set torque threshold when the winch is working, the winch controller drives the electric winch to stop or stop working after a delay and sends an alarm signal through the vehicle-mounted instrument and other vehicle-mounted alarms. The alarm signal mainly shows that there is a safety risk due to abnormal torque and suspends work to avoid safety accidents. The vehicle-mounted alarm uses vehicle-mounted instruments or vehicle-mounted IHU display screens to send corresponding reminders.

[0036] In a preferred embodiment, in the process of controlling the operation of the electric winch, if the real-time torque value is detected to be greater than the set threshold, a corresponding alarm signal is immediately issued to remind the user that the torque generated by the rescue at this time has reached the maximum threshold, and the torque is still greater than the maximum threshold after the maximum torque is reached and the timing starts t seconds later, then the electric winch is controlled to stop working and a corresponding stop work reminder is issued. The purpose of doing this is that after reaching the maximum torque, the winch and the cable may be at risk of damage, so a reminder needs to be issued, and the main purpose of still working ts after reaching the maximum torque threshold is to try whether the rescue is successful under the maximum torque ts. If the rescue is still not possible after reaching the maximum torque t seconds, it means that the electric winch of the vehicle cannot rescue the trapped vehicle, and there is no need to continue to use the maximum torque to work continuously on the electric winch at the risk of damage. At this time, the corresponding reminder signal is issued by the on-board instrument to stop the work of the electric winch. When the electric winch stops working, first control the electric winch to rotate in the opposite direction, rotate at a low speed and monitor the torque in real time, and stop the work of the electric winch when the torque is reduced to the set value.

[0037] In a preferred embodiment, the IHU host sends the corresponding forward and reverse instructions to the winch controller only after the forward and reverse buttons of the IHU soft switch are triggered for a set time, and immediately sends the corresponding stop working signal to the winch controller after the forward and reverse switches of the IHU soft switch are untriggered. The purpose of this is to avoid false triggering caused by briefly triggering the forward and reverse switches of the IHU soft switch. Only after the forward and reverse soft switches are pressed for a certain period of time, the corresponding instructions are sent to the winch controller to avoid the safety hazards caused by false triggering of the forward and reverse soft switches. When starting forward and reverse, press and hold the forward or reverse soft switch. When the soft switch is pressed for a certain period of time, the IHU will send the forward and reverse instructions to the winch controller. It needs to be pressed for a long time to be effective. Once the soft switch corresponding to the forward and reverse is de-triggered, after the soft switch is released, the IHU will immediately stop sending the corresponding control instructions after detecting this state. The winch controller will immediately stop the operation of the electric winch after stopping receiving the forward and reverse instructions.

[0038] When the electric winch is controlled by the IHU soft switch, in order to avoid the safety hazard caused by the electric winch rotating too fast and the defect of rotating too slowly for too long, the present application pre-sets the speed. After receiving the forward and reverse instructions from the I HU host, the winch controller controls the winch to run at the set speed until the torque reaches the set threshold. Because during the rescue, the cable is loose at the beginning and the torque is low at this time. At this time, the electric winch is controlled to rotate at the set speed to quickly straighten the rescue cable. The torque will increase after straightening. When the torque reaches the set threshold, it means that the cable has been straightened, so the speed must be reduced to the minimum value, or even 0. At this time, the main purpose is to increase the torque to increase the rescue force. Therefore, after rotating at the set speed to reach the set torque, the speed of the electric winch is controlled to be reduced to the set minimum speed or a speed close to 0. At this time, the torque will be increased to achieve the purpose of rescue.

[0039] In a preferred embodiment of the present application, the user triggers the automatic mode of the electric winch through the IHU soft switch, and the IHU host sends the command corresponding to the automatic mode to the winch controller. After receiving the automatic control command, the winch controller automatically controls the electric winch and displays the automatic working state in real time through the vehicle alarm. An automatic mode soft switch is set in the IHU soft switch. After the automatic mode soft switch is triggered to turn on, the IHU host receives the trigger of the automatic mode soft switch and sends an automatic control mode signal to the winch controller through the CAN signal. The winch controller enters the automatic control mode after receiving the automatic control mode signal. In the automatic control mode, the electric winch is controlled by the automatic control strategy. The automatic control strategy includes:

[0040] After receiving the automatic control mode command, the winch controller outputs a control signal to the electric winch, and controls the electric winch to rotate forward in a manner that the speed is first fast, then slow, and finally the speed is reduced to a small speed or even 0. The speed is related to the torque of the collected electric winch. When the detected torque gradually increases to the torque threshold when the cable is straightened, the speed is gradually reduced from the initial speed to a small speed or even 0 speed, and then the torque is increased at the same time to achieve the rescue of the trapped vehicle. Here, the initial speed and the speed reduction rate are calibrated and designed in advance with the torque. The purpose of this is that when the electric winch is used to rescue the trapped vehicle, when the cable is in a loose state at the beginning, as the electric winch rotates forward, the cable is gradually straightened until it is tightened and begins to stretch the trapped vehicle, thereby trying to pull up the vehicle to achieve rescue. In this process, in order to quickly realize the cable from loose to tight, reduce the rescue time, and avoid the safety hazards caused by the sudden tightening of the cable when the speed is always very fast, the speed is set here first fast and then slow, and then the speed is reduced to a very small speed or even 0 after the torque corresponding to the straightening and tightening of the cable is detected, and then the torque is increased to achieve rescue. The speed here refers to the speed of the motor in the electric winch. Because the rotation of the motor drives the winch to rotate and then pulls the cable for rescue, the rotation and speed can be characterized by collecting the speed of the motor.

[0041] After detecting that the torque reaches the torque when the cable is taut, the torque and speed of the electric winch are monitored in real time. When it is detected that the torque suddenly decreases and the speed increases, the rescue is judged to be successful. At this time, the winch controller controls the electric winch to stop forward rotation, and sends a reminder signal through the on-board instrument or IHU host. At the same time, the soft switch signal is collected in real time. When the soft switch signal that the electric winch stops working is received at this time, the winch controller drives the electric winch to reverse and retract the cable. The number of reverse turns is the same as the forward turn, and the encoder can be used to collect the number of turns of the electric winch to calculate the forward data. At the end, the electric winch is controlled to reverse according to the forward data, thereby achieving the purpose of ending the function of the electric winch to recover the cable.

[0042] If the torque is greater than the set maximum safety torque threshold during the real-time monitoring of the torque and speed of the electric winch, a corresponding alarm signal will be immediately issued to remind the user that the torque generated by the rescue has reached the maximum threshold, and if the torque is still greater than the maximum threshold after the maximum torque is reached and the timing starts t seconds later, the electric winch will be controlled to stop working and a corresponding stop work reminder will be issued. The purpose of this is that after reaching the maximum torque, the winch and the cable may be at risk of damage, so a reminder is required. The main purpose of still working after reaching the maximum torque threshold is to try whether the rescue is successful under the maximum torque. If the rescue is still not possible after reaching the maximum torque t seconds, it means that the electric winch of this vehicle cannot rescue the trapped vehicle, and there is no need to continue to use the maximum torque to work on the electric winch at the risk of damage. At this time, the corresponding reminder signal is issued by the on-board instrument to stop the work of the electric winch. When the electric winch stops working, first control the electric winch to rotate in the opposite direction, rotate at a low speed and monitor the torque in real time, and stop the work of the electric winch when the torque is reduced to the set value.

[0043] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
