[0068] Currently, most electric winches are low-voltage. Low-voltage electric winches have lower driving force and efficiency, making them unsuitable for certain scenarios. High-voltage electric winches can solve these problems, but during use, they may burn out the moment high-voltage current is applied, reducing their safety.

[0069] In this regard, some embodiments of the present disclosure provide a pre-charge control circuit for use in a vehicle. The pre-charge control circuit includes a pre-charge component, one end of which is connected to an energy storage component, and the other end of which is connected to a winch component. The pre-charge component is configured to pre-charge the winch component.

[0070] It is understood that the pre-charge control circuit provided in some embodiments of this disclosure can pre-charge the winch assembly through a pre-charge component connected to the energy storage component. This reduces the likelihood of the winch assembly burning out instantly upon connection to high-voltage current, thus improving the safety of the high-voltage electric winch.

[0071] The winch control system provided in some embodiments of this disclosure will now be described in conjunction with the accompanying drawings.

[0072] Referring to Figure 1, a winch control system 900 provided in an embodiment of the application includes: an energy storage component 100, a winch assembly 200, and a pre-charge control circuit 300. The pre-charge control circuit 300 is connected between the energy storage component 100 and the winch assembly 200.

[0073] It is understood that the winch control system provided in some embodiments of this disclosure connects the pre-charge control circuit 300 between the energy storage component 100 and the winch assembly 200, and the pre-charge control circuit 300 realizes the pre-charging of the winch assembly 200. In this way, the possibility of the winch assembly being burned out at the moment of connection of high voltage current can be reduced, and the safety of high voltage electric winch use can be improved.

[0074] The energy storage component 100, the winch component 200, and the pre-charge control circuit 300 will be described below.

[0075] In some embodiments, the energy storage component 100 is configured to provide a power source for the winch assembly 200.

[0076] For example, the energy storage component 100 can provide a power source for the winch assembly 200 through the high-voltage bus.

[0077] In some embodiments, the energy storage component 100 may include a battery pack (power battery pack) and a battery management system (BMS). The battery is an energy storage device for an electric vehicle and is composed of multiple battery cells or components. The battery management system is configured to monitor parameters such as the voltage, current, and temperature of the battery, as well as perform state estimation, fault judgment, safety protection, and energy management on the battery, etc.

[0078] In some embodiments, the winch component 200 is configured to provide the vehicle with the ability to get out of trouble.

[0079] In some embodiments, the winch component 200 may be a high-voltage electric winch component.

[0080] In some embodiments, the winch component 200 may include an electric control system, a motor, a rope guide component, a rope drum component, and a reduction gearbox component.

[0081] The electric control system is configured to control functions such as the start, stop, speed, and steering adjustment of the motor. The user can achieve remote control and precise operation of the winch component 200 through the electric control system.

[0082] The motor is the power source of the winch component 200 and is configured to provide the driving force required for the operation of the winch component 200. For example, the motor receives instructions from the electric control system, converts electrical energy into mechanical energy, and drives the winch to work.

[0083] The rope guide component is configured to guide the winding and release of the steel wire rope on the winch. The rope guide component can ensure that the steel wire rope always maintains an appropriate angle during the lifting operation, thereby ensuring the safety and reliability of the lifting process. The rope guide is usually composed of parts such as a rope guide wheel, a bracket, and a steel plate. Through the guidance of the rope guide wheel, the steel wire rope is always within the specified angle range during the lifting process.

[0084] The rope drum component is configured to wind and store the steel wire rope. During the operation of the winch component 200, the rope drum component will rotate with the rotation of the motor, thereby winding or releasing the steel wire rope.

[0085] The reduction gearbox component, a transmission component in the winch component 200, is configured to reduce the speed of the motor and increase the torque. Through the transmission effect of the reduction gearbox component, the winch can generate a greater traction force when operating at a low speed. The reduction gearbox component is usually composed of multiple gears, bearings, and other parts, and has the characteristics of a compact structure and high transmission efficiency.

[0086] In some embodiments, the pre-charge control circuit 300 is configured to perform pre-charging on the high-voltage devices of the entire vehicle, which can avoid large current impacts during the high-voltage power-on process and protect the components in the circuit.

[0087] Referring to Figure 2, it is a schematic diagram of the structure of a precharge control circuit 300 provided in some embodiments of this disclosure. As shown in Figure 2, the precharge control circuit 300 shown in Figure 1 may include a precharge component 310. One end of the precharge component 310 is connected to the energy storage component 100, and the other end of the precharge component 310 is connected to the winch component 200.

[0088] In some embodiments, the precharge component 310 is configured to precharge the winch assembly 200.

[0089] In some embodiments, the winch assembly 200 is a high-voltage electric winch assembly, the high-voltage winch assembly includes a capacitor, and the pre-charge assembly 310 is configured to pre-charge the capacitor in the high-voltage winch assembly.

[0090] It is understood that the pre-charge control circuit provided in some embodiments of this disclosure can pre-charge the winch assembly through a pre-charge component connected to the energy storage component. This reduces the likelihood of the winch assembly burning out instantly upon connection to high-voltage current, thus improving the safety of the high-voltage electric winch.

[0091] In some embodiments, as shown in FIG2, the precharge assembly 310 includes a precharge circuit 311. One end of the precharge circuit 311 is connected to the energy storage assembly 100, and the other end of the precharge circuit 311 is connected to the winch assembly 200. The precharge circuit 311 is configured to be turned on when the winch assembly 200 is precharged.

[0092] It is understood that one end of the pre-charge circuit 311 provided in some embodiments of this disclosure is connected to the energy storage component 100, and the other end is used to connect to the winch assembly 200, so that it can be turned on when the winch assembly 200 is pre-charged. In this way, the winch assembly 200 can save pre-charge circuit space and reduce costs by reusing the pre-charge circuit 311 of the energy storage component 100.

[0093] In some embodiments, as shown in FIG2, the precharge circuit 311 includes a resistor 311-1 and a first switching assembly 311-2 connected in series.

[0094] Resistor 311-1 is used for current limiting. Understandably, resistor 311-1 plays a current-limiting role during the pre-charging process, preventing excessive current from damaging components. For example, when the energy storage module 100 starts up, large-capacity capacitors (such as filter capacitors on the front end of high-voltage devices used to smooth the DC bus voltage and reduce current fluctuations) are usually in a low-voltage or fully discharged state. Without resistor 311-1, when the battery pack of the energy storage module 100 is directly connected to the capacitor through the main relay, a huge instantaneous charging current will be generated due to the large voltage difference. This could lead to damage to the relay contacts, overheating or even explosion of the capacitor, as well as short circuits or damage inside the battery pack. Therefore, resistor 311-1 effectively limits the magnitude of the initial charging current by providing a current-limiting path.

[0095] The first switching assembly 311-2 is used to connect or disconnect the pre-charge circuit 311. For example, during the pre-charge phase, the first switching assembly 311-2 is closed, causing the resistor 311-1 and the capacitor of the high-voltage device to form a circuit for pre-charge. During the pre-charge process, the capacitor of the high-voltage device acts as a load to receive electrical energy from the battery pack. When the voltage on the capacitor approaches a preset voltage value (e.g., the battery pack voltage), the first switching assembly 311-2 is disconnected, and the pre-charge ends.

[0096] It is understood that the pre-charge circuit 311 provided in some embodiments of this disclosure includes a resistor 311-1 and a first switching component 311-2. The resistor 311-1 enables the pre-charge current to increase gradually and smoothly, thereby improving the safety and stability of the entire system. The first switching component 311-2 is able to conduct during pre-charging and disconnect when pre-charging ends, preventing accidental contact and helping to reduce circuit failures and safety accidents caused by misoperation. Therefore, the pre-charge circuit 311 provided by this disclosure can improve system safety and stability.

[0097] It should be understood that the above description of the structure of the precharge circuit 311 is merely an example, and some embodiments of this disclosure are not limited thereto.

[0098] In some embodiments, as shown in FIG2, the precharge assembly 310 further includes a first power supply circuit 312. One end of the first power supply circuit 312 is used to connect to the energy storage assembly 100, and the other end of the first power supply circuit 312 is used to connect to the winch assembly 200. The first power supply circuit 312 is configured to disconnect during precharging of the winch assembly 200.

[0099] It is understood that the pre-charge component 310 provided in some embodiments of this disclosure also includes a first power supply circuit 312, which is configured to disconnect during the pre-charging of the winch assembly 200. This can effectively slow down the current rise rate, protect the winch assembly 200 from damage, and also avoid electric shock accidents caused by misoperation or other reasons during the pre-charging process, thereby improving safety.

[0100] In some embodiments, as shown in FIG2, the first power supply circuit 312 includes a second switch assembly 312-1. The second switch assembly 312-1 is used to turn the first power supply circuit 312 on or off.

[0101] It is understood that the first power supply circuit 312 provided in some embodiments of this disclosure includes a second switch assembly 312-1, which can turn the first power supply circuit 312 on or off. This can prevent accidental contact and help reduce circuit failures and safety accidents caused by misoperation.

[0102] In some embodiments, the precharge circuit 311 and the first power supply circuit 312 are connected in parallel.

[0103] In some embodiments, the precharge circuit 311 is further configured to disconnect when the precharge of the winch assembly 200 is complete, and the first power supply circuit 312 is further configured to turn on when the precharge of the winch assembly 200 is complete.

[0104] Understandably, the pre-charge circuit 311 disconnects when the pre-charging of the winch assembly 200 is complete. This avoids voltage fluctuations caused by continuous charging, maintains voltage stability, and protects the winch assembly 200 from damage. The first power supply circuit 312 is turned on when the pre-charging of the winch assembly 200 is complete, so that the winch assembly 200 can continuously draw power from the energy storage component 100, ensuring its normal operation.

[0105] In some embodiments, the pre-charging of the winch assembly 200 is completed when the difference between the voltage value corresponding to the preset capacitor of the winch assembly 200 and the preset voltage value is less than or equal to a first threshold.

[0106] The preset voltage value can be determined based on the battery pack voltage; for example, the preset voltage value can be the same as the battery pack voltage.

[0107] For example, the first threshold can be 10V.

[0108] For example, when the voltage on the capacitor of the winch assembly 200 reaches 95% of the preset voltage value, it is determined that the pre-charging of the winch assembly 200 is complete.

[0109] Understandably, during the pre-charging process, as the difference between the voltage value corresponding to the preset capacitor of the winch assembly 200 and the preset voltage value gradually decreases, it indicates that the winch assembly 200 gradually enters a stable state. When the voltage difference between the two is closer, the possibility of the winch assembly 200 being burned out the instantaneously when connected to high voltage current is lower. Therefore, this disclosure determines that the pre-charging of the winch assembly 200 is completed when the difference between the voltage value corresponding to the preset capacitor of the winch assembly 200 and the preset voltage value is less than or equal to the first threshold.

[0110] In some embodiments, one end of the precharge circuit 311 is used to connect to the positive output terminal of the energy storage component 100, and the other end of the precharge circuit 311 is used to connect to the positive input terminal of the winch assembly 200; or, one end of the precharge circuit 311 is used to connect to the negative output terminal of the energy storage component 100, and the other end of the precharge circuit 311 is used to connect to the positive input terminal of the winch assembly 200.

[0111] It is understood that some embodiments of this disclosure do not limit the connection method of the precharge circuit 311, making the connection method of the precharge circuit 311 more flexible.

[0112] In some embodiments, as shown in FIG2, the precharge component 310 further includes a second power supply circuit 313.

[0113] For example, one end of the pre-charge circuit 311 is used to connect to the positive output terminal of the energy storage component 100, and the other end of the pre-charge circuit 311 is used to connect to the positive input terminal of the winch assembly 200; one end of the second power supply circuit 313 is used to connect to the negative output terminal of the energy storage component 100, and the other end of the second power supply circuit 313 is used to connect to the negative input terminal of the winch assembly 200; or, one end of the pre-charge circuit 311 is used to connect to the negative output terminal of the energy storage component 100, and the other end of the pre-charge circuit 311 is used to connect to the negative input terminal of the winch assembly 200; one end of the second power supply circuit 313 is used to connect to the positive output terminal of the energy storage component 100, and the other end of the second power supply circuit 313 is used to connect to the positive input terminal of the winch assembly 200.

[0114] It is understood that the winch control system provided in some embodiments of this disclosure integrates the winch assembly 200 and the pre-charge control circuit 300, and pre-charges the winch assembly 200 through the pre-charge control circuit 300. This reduces the possibility of the winch assembly 200 being burned out the instant it is connected to high-voltage current, thus improving the safety of using the high-voltage electric winch.

[0115] In some embodiments, the precharge component 310 is configured to precharge the winch assembly after one or more designated circuits connected to the energy storage component 100 have completed a discharge operation.

[0116] For example, the aforementioned setting circuit is a circuit with a high voltage level, that is, the aforementioned setting circuit can be the high-voltage circuit of the entire vehicle. For example, the voltage of the setting circuit refers to a voltage of 60V or higher for direct current (DC) or 25Vrms or higher for alternating current (AC).

[0117] It is understandable that performing a discharge operation in a high-voltage circuit refers to releasing the charge in the high-voltage circuit to prevent damage to components and electric shock accidents, thereby improving the reliability and safety of the circuit.

[0118] In some embodiments, whether the setting circuit has completed the discharge operation is determined based on the voltage between the positive and negative terminals on the main circuit of the setting circuit. For example, if the voltage between the positive and negative terminals on the main circuit of the setting circuit is less than or equal to a preset safe voltage value, it is determined that the setting circuit has completed the discharge operation. For example, the preset safe voltage value can be 60V.

[0119] In some embodiments, as shown in FIG3, the precharge control circuit 300 further includes a power distribution component 320. One end of the power distribution component 320 is used to connect to the precharge component 310, and the other end of the power distribution component 320 is used to connect to the winch assembly 200. The power distribution component 320 is used to connect or disconnect the circuit between the precharge component 310 and the winch assembly 200.

[0120] It is understandable that a power distribution component 320 is provided between the precharge component 310 and the winch assembly 200 to connect or disconnect the circuit between the precharge component 310 and the winch assembly 200. This can prevent accidental contact and help reduce circuit failures and safety accidents caused by misoperation.

[0121] In some embodiments, as shown in FIG3, the power distribution assembly 320 includes a power distribution switch 321. One end of the power distribution switch 321 is connected to the precharge assembly 310, and the other end of the power distribution switch 321 is used to connect to the winch assembly 200. The power distribution switch 321 is configured to close during precharging of the winch assembly 200.

[0122] Understandably, the power distribution assembly 320 includes a power distribution switch 321, configured to close during pre-charging of the winch assembly 200, thereby connecting the circuit between the winch assembly 200 and the pre-charging assembly 310. This improves the reliability and safety of the circuit, thereby enhancing driving safety.

[0123] In some embodiments, the power distribution switch 321 includes at least one of a positive switch or a negative switch. One end of the positive switch is used to connect to the positive output terminal of the precharge component 310, and the other end is used to connect to the positive input terminal of the winch assembly 200; one end of the negative switch is used to connect to the negative output terminal of the precharge component 310, and the other end is used to connect to the negative input terminal of the winch assembly 200.

[0124] In some embodiments, the power distribution switch 321 is one of a relay, diode, transistor, field-effect transistor, or optocoupler.

[0125] In some embodiments, the power distribution component 320 is configured to reconnect the circuit between the precharge component 310 and the winch component 200 after one or more designated circuits connected to the energy storage component 100 have completed a discharge operation.

[0126] In some embodiments, as shown in FIG3, the precharge control circuit 300 further includes a voltage conversion component 330. One end of the voltage conversion component 330 is used to connect to the energy storage component 100 or the precharge component 310, and the other end of the voltage conversion component 330 is used to connect to the vehicle's power supply port.

[0127] For example, voltage conversion component 330 can be a direct current to direct current (DC-DC) converter. The DC-DC converter can convert high-voltage direct current from the battery pack of energy storage component 100 into low-voltage direct current to power the low-voltage load of the vehicle.

[0128] In some embodiments, during the discharge operation of the high-voltage circuit of the vehicle, the low-voltage power supply remains normal, that is, the DC-DC converter works normally to provide low-voltage power to the vehicle.

[0129] In some embodiments, during the discharge operation of the high-voltage circuit of the vehicle, a 12V battery can be connected to the vehicle's power supply port to provide low-voltage power to the vehicle.

[0130] In some embodiments, as shown in FIG3, the precharge control circuit 300 further includes a first control component 340. The first control component 340 is connected to the precharge component 310 and is configured to control the on / off state of the precharge component 310.

[0131] It is understood that in some embodiments of this disclosure, the first control component 340 can control the on / off state of the precharge component 310, thereby enabling precise control of the precharge process and improving the reliability and safety of the circuit.

[0132] For example, the first control component 340 can be a vehicle control unit (VCU).

[0133] For example, the first control component 340 is configured to control the on / off state of the precharge component 310, including controlling the first switch component 311-2 on the precharge circuit 311 of the precharge component 310 to close or open, thereby realizing the on / off state of the precharge component 310.

[0134] For example, the first control component 340 is configured to control the precharge component 310 to be turned on in response to a winch mode start command to precharge the winch component 200.

[0135] For example, the first control component 340 is configured to control the pre-charge component 310 to disconnect when it is determined that the winch assembly 200 has completed pre-charging.

[0136] In some embodiments, the first control component 340 is configured to control the precharge component 310 to conduct in response to a winch mode start command to precharge the winch component 200, including: sending a discharge operation command in response to the winch mode start command, the discharge operation command being used to cause one or more set circuits connected to the energy storage component 100 to perform a discharge operation; and after the discharge operation is completed, controlling the precharge component 310 to conduct to precharge the winch component 200.

[0137] It is understandable that setting the circuit to perform a discharge operation means releasing the charge in the set circuit to avoid damage to components and electric shock accidents, thereby improving the reliability and safety of the circuit.

[0138] In some embodiments, the first control component 340 determines whether the setting circuit has completed a discharge operation based on the voltage between the positive and negative terminals on the main line of the setting circuit. For example, if the voltage between the positive and negative terminals on the main line of the setting circuit is less than or equal to a preset safe voltage value, it is determined that the setting circuit has completed a discharge operation. For example, the preset safe voltage value can be 60V.

[0139] In some embodiments, after the set circuit completes the venting operation, the first control component 340 may send a venting completion message to the vehicle's domain controller to indicate that the set circuit has completed the venting operation.

[0140] It is understandable that the winch assembly 200 is usually located inside the front bumper of the vehicle. Therefore, for driving safety, the winch assembly 200 is not connected to high voltage when the winch mode is not activated, and the high voltage is connected to the winch assembly 200 when the winch mode is activated.

[0141] Because the charge energy on the set circuit is high during vehicle operation, connecting the winch assembly 200 at this time may damage its components or cause an electric shock. Therefore, in some embodiments of this disclosure, after receiving the winch mode start command, the first control component 340 first controls the set circuit to perform a discharge operation, and then performs pre-charging and re-applies high voltage after the set circuit completes the discharge operation. This improves the reliability and safety of the circuit.

[0142] In some embodiments, the first control component 340 is further configured to turn on the first power supply circuit 312 after the winch assembly 200 has completed precharging. For example, the first power supply circuit 312 includes a second switch assembly 312-1, and the first control component 340 can turn on the first power supply circuit 312 by controlling the second switch assembly 312-1 to close.

[0143] In some embodiments, the first control component 340 is connected to the power distribution component 320, and the first control component 340 is further configured to control the on / off state of the power distribution component 320.

[0144] It is understood that in some embodiments of this disclosure, the first control component 340 can control the on / off state of the power distribution component 320, thereby enabling precise control of the pre-charging process and improving the reliability and safety of the circuit.

[0145] For example, the first control component 340 is also configured to control the on / off state of the power distribution component 320, including: the first control component 340 controls the power distribution component 320 to be closed or opened by controlling the power distribution switch 321 of the power distribution component 320 to achieve the on / off state of the power distribution component 320.

[0146] For example, the distribution switch 321 includes at least one of a positive switch or a negative switch.

[0147] For example, the first control component 340 is configured to control the power distribution component 320 to close during the pre-charging of the winch assembly 200, thereby connecting the circuit between the pre-charging component 310 and the winch assembly 200.

[0148] In some embodiments, the first control component 340 is configured to: in response to a winch mode start command, after one or more set circuits connected to the energy storage component 100 have completed a discharge operation, control the power distribution component 320 to close to conduct the circuit between the precharge component 310 and the winch component 200; or, conduct the circuit between the energy storage component 100 and the winch component 200.

[0149] For example, after determining that the set circuit has completed the discharge operation, the first control component 340 generates a power distribution component closing command and sends the power distribution component closing command to the winch assembly 200 through the vehicle's internal communication network (e.g., CAN bus); in response to the power distribution component closing command, the electronic control system in the winch assembly 200 controls at least one of the positive or negative switches in the power distribution component 320 to close. For example, the electronic control system can send a control command to at least one of the positive or negative switches to perform the closing operation.

[0150] For example, after determining that the set circuit has completed the discharge operation, the first control component 340 generates a power distribution component closing command and sends the power distribution component closing command to the power distribution component 320 through the vehicle's internal communication network (e.g., CAN bus); in response to the power distribution component closing command, the power distribution component 320 controls at least one of the positive or negative switches to close.

[0151] For example, after determining that the set circuit has completed the discharge operation, the first control component 340 generates a power distribution component closing command and sends the power distribution component closing command to at least one of the positive or negative switches in the power distribution component 320 through the vehicle's internal communication network (e.g., CAN bus) so that the closing of at least one of the positive or negative switches in response to the power distribution component closing command performs a closing operation.

[0152] For example, the closing command of the aforementioned power distribution component can be an electrical signal, such as a voltage signal or a current signal.

[0153] In some embodiments, the first control component 340 is further configured to: control the power distribution component 320 to disconnect in response to a winch mode shutdown command, thereby disconnecting the circuit between the precharge component 310 and the winch component 200; or, disconnect the circuit between the energy storage component 100 and the winch component 200.

[0154] It is understandable that the winch assembly 200 is usually located inside the front bumper of the vehicle. Therefore, for driving safety, the winch assembly 200 is not connected to high voltage when the winch mode is not activated, and the high voltage is connected to the winch assembly 200 when the winch mode is activated.

[0155] Therefore, some embodiments of this disclosure include a power distribution switch 321 in the power distribution assembly 320. By controlling the closing or opening of the power distribution switch 321, the connection between the winch assembly 200 and the high-voltage circuit can be controlled. This improves the reliability and safety of the circuit, thereby enhancing driving safety.

[0156] In some embodiments, the winch assembly 200 and the vehicle's high-voltage circuit share the precharge assembly 310. This reduces the number of components, saves space in the precharge circuit, and optimizes system costs while ensuring a good user experience.

[0157] In some embodiments, as shown in FIG4, the winch control system further includes a second control component 400, which is communicatively connected to the winch assembly 200. The second control component 400 is configured to send control commands to the winch assembly 200 to cause the winch assembly 200 to perform corresponding operations.

[0158] Understandably, the second control component 400 can control the winch assembly 200, for example, by controlling its start-up, shutdown, speed adjustment, and direction adjustment. Thus, precise control of the winch assembly 200 can be achieved through the second control component 400.

[0159] For example, the second control component 400 can be a domain controller.

[0160] In some embodiments, the second control component 400 is further configured to handle message interaction between the energy network, the smart access network, and the vehicle network. The energy network is the network system in the vehicle responsible for energy management and distribution. It monitors and manages the energy flow and consumption of components such as the battery pack, motor controller, and DC-DC converter in the electric vehicle. The smart access network is the network system in the vehicle responsible for vehicle access control and safety management.

[0161] For example, the intelligent access network provides functions such as keyless entry, identity verification, and security monitoring. The body network is the network system within the vehicle responsible for body control and comfort. For example, the body network provides functions such as body control, comfort management, and fault diagnosis.

[0162] In some embodiments, as shown in FIG4, the winch control system further includes a terminal component 500. The terminal component 500 is configured to output operating information of the winch assembly 200.

[0163] For example, the terminal component 500 is configured to output parameters such as the operating state (e.g., start or stop), speed, and direction of the winch component 200.

[0164] For example, when the winch assembly 200 is activated, the terminal component 500 can output corresponding icon or text prompts to inform the driver that the winch assembly 200 is in working condition. Similarly, when the winch assembly 200 is deactivated, the terminal component 500 will also update the status information in a timely manner.

[0165] For example, the terminal component 500 can output the rotational speed of the winch component 200 in real time. By monitoring the rotational speed, the operator can better control the working rhythm of the winch and avoid overload or excessive wear.

[0166] For example, when the winch assembly 200 has a bidirectional rotation function, the terminal assembly 500 can output the direction of the winch assembly 200 in real time, thereby improving the convenience and accuracy of operation.

[0167] In some embodiments, the terminal component 500 is also configured to output the remaining power of the vehicle battery, helping the driver to understand the available time of the winch component 200 and plan the work process in advance.

[0168] In some embodiments, when the winch assembly 200 malfunctions, the terminal assembly 500 is also configured to issue an alarm message and display fault information so that the driver can take timely measures to repair it.

[0169] In some embodiments, the terminal component 500 may also be configured to display images of the vehicle exterior, rescue vehicles, vehicle self-rescue, rope retraction and release switches, and demonstration images of winch usage.

[0170] In some embodiments, the terminal component 500 is also configured to interact with the user, for example, to adjust the operating parameters of the winch component 200 in response to the user's adjustment operation.

[0171] In some embodiments, the terminal component 500 is further configured to send a control command corresponding to the control operation to the winch component 200 in response to a control operation on the winch component 200, so that the winch component 200 performs the corresponding operation.

[0172] For example, if the above control operation can be a winch mode start operation, then the control command corresponding to the control operation can be a winch mode start command.

[0173] For example, if the above control operation is a winch mode shutdown operation, the control command corresponding to the control operation can be a winch mode shutdown command.

[0174] For example, if the above control operation can be a speed adjustment operation of the winch assembly 200, then the control command for the control operation can be a speed adjustment command for the winch assembly 200.

[0175] For example, the control operation described above can be a steering adjustment operation of the winch assembly 200, and the control command corresponding to the control operation can be a steering adjustment command of the winch assembly 200.

[0176] Understandably, users can issue control commands through the terminal component 500 to remotely control the winch component 200, which is convenient and improves the user experience.

[0177] For example, terminal component 500 may include a display screen, such as a panel display device (PAD) or a touch screen.

[0178] The terminal component 500 satisfies at least one of the following: the terminal component 500 can display the working information of the winch component 200 on the display screen, or the terminal component 500 can interact with the user through the display screen, for example, by receiving the user's control operation on the winch component 200 through the display screen.

[0179] It is understood that by executing at least one of the following through the terminal component: outputting the working information of the winch component, or receiving control operations for the winch component, the user can be informed of the working status of the winch component in a timely manner, and can achieve precise control of the winch component through human-machine interaction.

[0180] In some embodiments, as shown in FIG4, the second control component 400 is connected to the terminal component 500. The terminal component 500 can send control commands corresponding to the control operation to the winch component 200 through the second control component 400, so that the winch component 200 performs the corresponding operation.

[0181] For example, the terminal component 500 sends a control command corresponding to the control operation to the second control component 400, the second control component 400 receives the control command sent by the terminal component 500, and sends the control command to the winch component 200.

[0182] It is understandable that the second control component 400 can control the winch component 200 based on the control commands corresponding to the control operations sent by the terminal component 500.

[0183] For example, in response to a user's control operation, the control command issued by the terminal component 500 can be a winch mode start command. Then, the second control component 400 can send the winch mode start command to the winch component 200 to start the winch component 200.

[0184] For example, in response to a user's control operation, the control command issued by the terminal component 500 can be a winch mode shutdown command. In this case, the second control component 400 can send the winch mode shutdown command to the winch component 200 to shut down the winch component 200.

[0185] For example, in response to a user's control operation, the control command issued by the terminal component 500 can be a speed adjustment command for the winch component 200. Then, the second control component 400 can send the speed adjustment command to the winch component 200 to adjust the speed of the winch component 200.

[0186] For example, in response to a user's control operation, the control command issued by the terminal component 500 can be a steering adjustment command for the winch component 200. Then, the second control component 400 can send the steering adjustment command to the winch component 200 to adjust the steering of the winch component 200.

[0187] In some embodiments, the second control component 400 and the first control component 340 in the precharge control circuit 300 can be connected through the vehicle's communication network (e.g., CAN bus). In this case, the second control component 400 can also send the control commands received from the terminal component 500 to the first control component 340.

[0188] For example, when the second control component 400 receives a winch mode start command from the terminal component 500, it can send the winch mode start command to the first control component 340. When the second control component 400 receives a winch mode stop command from the terminal component 500, it can send the winch mode stop command to the first control component 340.

[0189] This disclosure also provides a winch control method in some embodiments, applied to the pre-charge control circuit of the winch control system described above. For example, as shown in FIG5, the winch control method provided in some embodiments of this disclosure includes the following steps.

[0190] S801, in response to the winch mode start command, controls the pre-charge component to pre-charge the winch component.

[0191] The aforementioned winch mode start command can be a winch mode start command issued by the terminal component in response to a user's input of a winch mode start operation in the terminal component. For example, if the terminal component is connected to a second control component, the winch mode start command can be sent from the terminal component to the second control component, and then from the second control component to the first control component in the predictive control circuit.

[0192] In some embodiments, the pre-charge component includes a pre-charge circuit. One end of the pre-charge circuit is used to connect to the energy storage component, and the other end of the pre-charge circuit is used to connect to the winch component. Therefore, step S801 can be implemented as follows: in response to a winch start command, controlling the pre-charge circuit to conduct to pre-charge the winch component.

[0193] If the precharge circuit of the precharge component includes a first switch assembly, then the above-mentioned control of the precharge circuit to conduct includes: in response to the winch mode start command, controlling the first switch assembly on the precharge circuit to close, so that the precharge circuit is conducted.

[0194] In some embodiments, the winch assembly is a high-voltage winch assembly.

[0195] In some embodiments, the high-voltage winch assembly includes a capacitor, then step S801 above can be implemented as: controlling the pre-charge circuit to conduct in order to pre-charge the capacitor in the high-voltage winch assembly.

[0196] It is understood that the winch control method provided in some embodiments of this disclosure can precharge the winch assembly by controlling the pre-charging component. This reduces the possibility of the winch assembly burning out the moment it is connected to high-voltage current, thus improving the safety of using the high-voltage electric winch.

[0197] In some embodiments, as shown in FIG6, step S801 above can be implemented as the following steps:

[0198] S8011, in response to the winch mode start command, sends a discharge operation command.

[0199] The discharge operation command is used to cause one or more designated loops connected to the energy storage component to perform a discharge operation.

[0200] For example, the discharge operation command is sent by the first control component to the device in the set circuit; accordingly, the device in the set circuit performs the discharge operation after receiving the discharge operation command.

[0201] It is understandable that setting the circuit to perform a discharge operation means releasing the charge in the set circuit to avoid damage to components and electric shock accidents, thereby improving the reliability and safety of the circuit.

[0202] S8012. After the discharge operation is completed, control the pre-charge component to conduct and pre-charge the winch assembly.

[0203] In some embodiments, whether the setting circuit has completed the discharge operation is determined based on the voltage between the positive and negative terminals on the main circuit of the setting circuit. For example, if the voltage between the positive and negative terminals on the main circuit of the setting circuit is less than or equal to a preset safe voltage value, it is determined that the setting circuit has completed the discharge operation. For example, the preset safe voltage value can be 60V.

[0204] It is understandable that the winch assembly is typically located inside the front bumper of the vehicle. Therefore, for driving safety, the winch assembly is not connected to high-voltage power when the winch mode is not activated, and is only connected to high-voltage power when the winch mode is activated. Since the charge energy on the set circuit is high during vehicle operation, connecting the winch assembly at this time could damage its components or cause an electric shock. Therefore, in some embodiments of this disclosure, after receiving the winch mode activation command, the first control component first controls the set circuit to perform a discharge operation, and then, after the set circuit completes the discharge operation, performs pre-charging and re-applies high voltage. This improves the reliability and safety of the circuit.

[0205] In some embodiments, the precharge control circuit further includes a power distribution component. One end of the power distribution component is used to connect to the precharge component, and the other end is used to connect to the winch assembly. The power distribution component is used to connect or disconnect the circuit between the precharge component and the winch assembly.

[0206] In some embodiments, the method further includes controlling the on / off state of the power distribution components.

[0207] For example, the power distribution assembly includes a power distribution switch. One end of the power distribution switch is connected to the pre-charge assembly, and the other end is used to connect to the winch assembly. Therefore, controlling the on / off state of the power distribution assembly can be achieved by controlling the closing or opening of the power distribution switch.

[0208] For example, a power distribution switch includes at least one of a positive switch or a negative switch.

[0209] In some embodiments, the above-mentioned control of the on / off state of the power distribution component includes: controlling the power distribution component to close during the pre-charging of the winch assembly to conduct the circuit between the pre-charging component and the winch assembly.

[0210] In some embodiments, the control of the power distribution component's on / off state includes: in response to a winch mode start command, after one or more pre-defined circuits connected to the energy storage component have completed a discharge operation, controlling the power distribution component to close to conduct the circuit between the pre-charge component and the winch component; or, conducting the circuit between the energy storage component and the winch component.

[0211] In some embodiments, the above-mentioned control of the power distribution component's on / off state includes: in response to a winch mode shutdown command, controlling the power distribution component to disconnect to disconnect the circuit between the precharge component and the winch component; or, disconnecting the circuit between the energy storage component and the winch component.

[0212] Understandably, for driving safety, when the winch mode is not activated, the winch assembly is not connected to high-voltage power, and the power distribution switch is open. When the winch mode is activated, the power distribution switch is closed to connect the energy storage unit and the winch assembly, thus connecting the winch assembly to the high-voltage circuit. This improves the reliability and safety of the circuit, thereby enhancing driving safety.

[0213] In some embodiments, after step S801, the method further includes: controlling the pre-charge circuit to disconnect after the winch assembly pre-charge is completed.

[0214] The above-mentioned control of the precharge circuit disconnection can be achieved by controlling the first switching component on the precharge circuit to disconnect.

[0215] In some embodiments, the pre-charging of the winch assembly is completed when the difference between the voltage value corresponding to the preset capacitor of the winch assembly and the preset voltage value is less than or equal to a first threshold.

[0216] The preset voltage value can be determined based on the battery pack voltage; for example, the preset voltage value can be the same as the battery pack voltage.

[0217] For example, the first threshold can be 10V.

[0218] For example, when the voltage on the capacitor of the winch assembly 200 reaches 95% of the preset voltage value, it is determined that the pre-charging of the winch assembly 200 is complete.

[0219] In some embodiments, after step S801, the method further includes: controlling the first power supply circuit to conduct after the winch assembly has completed pre-charging. For example, if the first power supply circuit includes a second switch assembly, then controlling the first power supply circuit to conduct can be achieved by controlling the second switch assembly to close, thereby conducting the first power supply circuit.

[0220] In summary, based on the winch control method provided in some embodiments of this disclosure, the winch assembly and pre-charge control circuit are integrated, and the winch assembly is pre-charged by the vehicle's pre-charge assembly. This reduces the possibility of the winch assembly burning out the moment it is connected to high-voltage current, improving the safety of the high-voltage electric winch. Simultaneously, the winch assembly and the vehicle's high-voltage circuit share the pre-charge assembly, reducing the number of components, saving space in the pre-charge circuit, and optimizing system costs while ensuring a good user experience. Furthermore, in some embodiments of this disclosure, upon receiving a winch mode start command, the entire vehicle is first de-energized, then pre-charged by the pre-charge assembly before the vehicle is re-energized, improving circuit reliability and safety, thereby enhancing driving safety.

[0221] The following describes the operation procedure for the winch control system to enter winch mode, based on the winch control system provided in the above embodiments.

[0222] For example, as shown in Figure 7, the operation procedure for the winch control system to enter winch mode includes the following steps:

[0223] S901, the terminal component responds to the winch mode start operation by sending a winch mode start command to the second control component.

[0224] S902, the second control component receives the winch mode start command sent by the terminal component and sends the winch mode start command to the winch component.

[0225] S903, the second control component sends a winch mode start command to the first control component.

[0226] S904. In response to the winch mode start command, the first control component sends a discharge operation command, which is used to cause one or more set circuits connected to the energy storage component to perform a discharge operation.

[0227] S905. After the discharge operation is completed, the first control component controls the pre-charge circuit of the pre-charge component to be turned on to pre-charge the winch component.

[0228] S906. After the discharge operation is completed, the first control component controls the power distribution component to connect the circuit between the energy storage component and the winch component.

[0229] For example, the first control component controls the closing of the power distribution switch in the power distribution component to conduct the circuit between the energy storage component and the winch component.

[0230] It should be noted that some embodiments of this disclosure do not limit the execution order of steps S905 and S906. In actual use, step S905 can be executed first and then step S906; or step S906 can be executed first and then step S905; or steps S905 and S906 can be executed simultaneously.

[0231] S907, the pre-charge component pre-charges the winch assembly.

[0232] S908. After the winch assembly has completed pre-charging, the first control component controls the pre-charging circuit of the pre-charging component to disconnect.

[0233] For example, when the first control component detects that the voltage in the winch assembly is close to a preset voltage value (e.g., battery pack voltage), it determines that the winch assembly is pre-charged.

[0234] S909, the first control component controls the first power supply circuit to be turned on.

[0235] The first power supply circuit includes a second switching assembly. The first control assembly controls the second switching assembly to close, thereby enabling the first power supply circuit to conduct.

[0236] Understandably, when a vehicle is about to be connected to high-voltage electricity, the first control component will first control the pre-charging circuit to operate for pre-charging. This process allows the voltage across the capacitor to gradually increase, preventing excessive inrush current when the second switching component is closed. After pre-charging is complete, the first control component will control the second switching component to close, at which point the first power supply circuit is connected, and the vehicle's high-voltage equipment is officially connected to the circuit.

[0237] S910. The first control component is powered on again, and the display status on the instrument panel is confirmed to be normal.

[0238] For example, if the dashboard displays "OK" or "READY", it means that the vehicle has been successfully connected to high voltage.

[0239] S911, the winch assembly begins operation.

[0240] S912. During the operation of the winch assembly, the terminal component can display the operating parameters of the winch assembly.

[0241] For example, the terminal component is also configured to interact with the user, such as adjusting the operating parameters of the winch component in response to the user's adjustment operation.

[0242] For example, the terminal component is also configured to send control commands corresponding to the input operation to the winch component in response to the input operation.

[0243] In summary, the winch control system provided by some embodiments of this disclosure can integrate the winch assembly and the pre-charge circuit assembly, and pre-charge the winch assembly through the vehicle's pre-charge circuit assembly. This reduces the possibility of the winch assembly burning out the moment it is connected to high-voltage current, thus improving the safety of using the high-voltage electric winch.

[0244] Meanwhile, the winch assembly shares a pre-charge component with the vehicle's high-voltage circuit, which reduces the number of components, saves space in the pre-charge circuit, and optimizes system costs while ensuring a good user experience. Furthermore, controlling the connection between the winch assembly and the high-voltage circuit by opening or closing the power distribution switch of the power distribution component improves circuit reliability and safety, thereby enhancing driving safety.

[0245] Based on the operation process of the winch control system entering winch mode provided by some embodiments of this disclosure, upon receiving the winch mode start command, a high-voltage discharge operation is first performed, followed by pre-charging through the pre-charging component, and then the operation of applying high voltage to the vehicle is performed. This can improve the reliability and safety of the circuit, thereby improving driving safety.
