[0065] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0066] As mentioned in the background technology, most electric winches are currently low-voltage electric winches. Low-voltage electric winches have a small driving force and low efficiency, cannot meet the needs of specific scenarios, and have a poor user experience. High-voltage electric winches can solve the above problems, but during use, high-voltage electric winches may be burned out at the moment of access to high-voltage current, reducing the safety of using high-voltage electric winches.

[0067] In this regard, an embodiment of the present application provides a pre-charging control circuit, which is applied to a vehicle, and the pre-charging control circuit includes: a pre-charging module, one end of the pre-charging module is used to connect to the energy storage module, and the other end of the pre-charging module is used to connect to the winch module; the pre-charging module is used to pre-charge the winch module. It can be understood that the pre-charging control circuit provided in the embodiment of the present application can pre-charge the winch module through the pre-charging module connected to the energy storage module. In this way, the possibility of the winch module being burned out at the moment of accessing the high-voltage current can be reduced, thereby improving the safety of the use of the high-voltage electric winch.

[0068] The winch control system provided in the embodiment of the present application is introduced below in conjunction with the drawings of the specification.

[0069] See also Figure 1 , a winch control system provided in an embodiment of the application includes: an energy storage module 100, a winch module 200, and a pre-charge control circuit 300. The pre-charge control circuit 300 is connected between the energy storage module 100 and the winch module 200.

[0070] It is understandable that the winch control system provided in the embodiment of the present application connects the pre-charge control circuit 300 between the energy storage module 100 and the winch module 200, and pre-charges the winch module 200 through the pre-charge control circuit 300. In this way, the possibility of the winch module being burned out at the moment of accessing the high-voltage current can be reduced, and the safety of the high-voltage electric winch can be improved.

[0071] Next, the energy storage module 100 , the winch module 200 , and the pre-charge control circuit 300 are described respectively.

[0072] In some embodiments, the energy storage module 100 is used to provide a power source for the winch module 200 .

[0073] Exemplarily, the energy storage module 100 may provide a power source for the winch module 200 via a high-voltage bus.

[0074] In some embodiments, the energy storage module 100 may include a battery pack (power battery pack) and a battery management system (BMS). The battery is an energy storage device for electric vehicles, which is composed of multiple battery cells or modules. The battery management system is used to monitor the battery's voltage, current, temperature and other parameters, as well as to estimate the battery's state, diagnose faults, provide safety protection, and manage energy.

[0075] In some embodiments, the winch module 200 is used to provide a vehicle with an escape capability.

[0076] In some embodiments, the winch module 200 may be a high voltage electric winch module.

[0077] In some embodiments, the winch module 200 may include: an electric control system, a motor, a rope guide assembly, a rope drum assembly, and a reduction gearbox assembly.

[0078] The electric control system is used to control the start, stop, speed and steering of the motor, etc. The user can remotely control and precisely operate the winch module 200 through the electric control system.

[0079] The motor is the power source of the winch module 200, and is used to provide the driving force required for the operation of the winch module 200. Exemplarily, the motor converts electrical energy into mechanical energy by receiving instructions from the electronic control system, and drives the winch to work.

[0080] The rope guide assembly is used to guide the winding and release of the wire rope on the winch. The rope guide assembly can ensure that the wire rope always maintains a suitable angle during the lifting operation, thereby ensuring the safety and reliability of the lifting process. The rope guide is usually composed of a rope guide wheel, a bracket and a steel plate. Through the guidance of the rope guide wheel, the wire rope is always within the specified angle range during the lifting process.

[0081] The rope drum assembly is used for winding and storing the wire rope. During the operation of the winch module 200, the rope drum assembly rotates with the rotation of the motor, thereby winding or releasing the wire rope.

[0082] The reduction box assembly is a transmission component in the winch module 200, which is used to reduce the speed of the motor and increase the torque. Through the transmission effect of the reduction box assembly, the winch can generate greater traction when running at a low speed. The reduction box assembly is usually composed of multiple gears and bearings and other components, and has the characteristics of compact structure and high transmission efficiency.

[0083] In some embodiments, the pre-charge control circuit 300 is used to pre-charge the high-voltage devices of the entire vehicle, which can avoid large current shocks during the high-voltage power-on process and protect the components in the circuit.

[0084] See also Figure 2 , is a schematic diagram of the structure of a pre-charge control circuit 300 provided in an embodiment of the present application. Figure 2 As shown, Figure 1 The pre-charging control circuit 300 shown in FIG. 3 may include a pre-charging module 310 . One end of the pre-charging module 310 is used to connect to the energy storage module 100 , and the other end of the pre-charging module 310 is used to connect to the winch module 200 .

[0085] In some embodiments, the pre-charging module 310 is used to pre-charge the winch module 200 .

[0086] In some embodiments, the winch module 200 is a high-voltage electric winch module, the high-voltage winch module includes a capacitor, and the pre-charging module 310 is specifically used to pre-charge the capacitor in the high-voltage winch module.

[0087] It is understandable that the pre-charge control circuit provided in the embodiment of the present application can pre-charge the winch module through the pre-charge module connected to the energy storage module. In this way, the possibility of the winch module being burned out at the moment of accessing the high-voltage current can be reduced, and the safety of the high-voltage electric winch can be improved.

[0088] In some embodiments, Figure 2 As shown, the pre-charging module 310 includes a pre-charging circuit 311. One end of the pre-charging circuit 311 is used to connect the energy storage module 100, and the other end of the pre-charging circuit 311 is used to connect the winch module 200. The pre-charging circuit 311 is configured to be turned on when pre-charging the winch module 200.

[0089] It is understandable that the pre-charging circuit 311 provided in the embodiment of the present application is connected to the energy storage module 100 at one end and connected to the winch module 200 at the other end, and can be turned on when pre-charging the winch module 200. In this way, the winch module 200 can save pre-charging circuit space and reduce costs by reusing the pre-charging circuit 311 of the energy storage module 100.

[0090] In some embodiments, Figure 2 As shown, the pre-charging loop 311 includes a resistor 311 - 1 and a first switch module 311 - 2 connected in series.

[0091] Among them, resistor 311-1 is used for current limiting. It is understandable that resistor 311-1 plays a current limiting role in the pre-charging process to prevent excessive current from causing damage to components. Exemplarily, when the energy storage module 100 is started, the large-capacity capacitor (such as the filter capacitor set on the front end of the high-voltage device for smoothing the DC bus voltage and reducing current fluctuations) is usually in a low voltage or fully discharged state. If there is no 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, which may cause damage to the relay contacts, overheating or even explosion of the capacitor, and short circuit or damage inside the battery pack. Therefore, resistor 311-1 effectively limits the size of the initial charging current by providing a current limiting path.

[0092] The first switch module 311-2 is used to turn on or off the pre-charging circuit 311. Exemplarily, in the pre-charging stage, the first switch module 311-2 is closed, so that the resistor 311-1 and the capacitor of the high-voltage device form a loop for pre-charging. In the pre-charging process, the capacitor of the high-voltage device receives electrical energy from the battery pack as a load. When the voltage on the capacitor approaches a preset voltage value (such as the battery pack voltage), the first switch module 311-2 is disconnected, and the pre-charging ends.

[0093] It can be understood that the pre-charging circuit 311 provided in the embodiment of the present application includes a resistor 311-1 and a first switch module 311-2. Among them, the pre-charging current can be gradually and steadily increased through the resistor 311-1, thereby improving the safety and stability of the entire system; the first switch module 311-2 can be turned on during pre-charging and disconnected at the end of pre-charging, which can avoid false touches and help reduce circuit failures and safety accidents caused by misoperation. Therefore, the pre-charging circuit 311 provided in the present application can improve system safety and stability.

[0094] It should be understood that the above description of the structure of the pre-filling circuit 311 is merely exemplary and the embodiments of the present application are not limited thereto.

[0095] In some embodiments, Figure 2 As shown, the pre-charging module 310 further includes a first power supply circuit 312. One end of the first power supply circuit 312 is used to connect the energy storage module 100, and the other end of the first power supply circuit 312 is used to connect the winch module 200. The first power supply circuit 312 is configured to be disconnected when pre-charging the winch module 200.

[0096] It can be understood that the pre-charging module 310 provided in the embodiment of the present application also includes a first power supply circuit 312, which is configured to be disconnected when pre-charging the winch module 200. In this way, the current rising speed can be effectively slowed down to protect the winch module 200 from damage. At the same time, it can also avoid electric shock accidents caused by misoperation or other reasons during the pre-charging process, thereby improving safety.

[0097] In some embodiments, Figure 2 As shown, the first power supply loop 312 includes a second switch module 312 - 1 . The second switch module 312 - 1 is used to switch on or off the first power supply loop 312 .

[0098] It can be understood that the first power supply circuit 312 provided in the embodiment of the present application includes a second switch module 312-1, which can turn on or off the first power supply circuit 312, thereby avoiding accidental touches and helping to reduce circuit failures and safety accidents caused by incorrect operations.

[0099] In some embodiments, the pre-charging loop 311 and the first power supply loop 312 are connected in parallel.

[0100] In some embodiments, the pre-charging circuit 311 is further configured to be disconnected when the pre-charging of the winch module 200 is completed, and the first power supply circuit 312 is further configured to be connected when the pre-charging of the winch module 200 is completed.

[0101] It is understandable that the pre-charging circuit 311 is disconnected when the pre-charging of the winch module 200 is completed, so that voltage fluctuations caused by continuous charging can be avoided, the voltage can be maintained stable, and the winch module 200 can be protected from damage. The first power supply circuit 312 is turned on when the pre-charging of the winch module 200 is completed, so that the winch module 200 can continuously obtain power from the energy storage module 100 to ensure its normal operation.

[0102] In some embodiments, when the difference between the voltage value corresponding to the preset capacitance of the winch module 200 and the preset voltage value is less than or equal to the first threshold, the pre-charging of the winch module 200 is completed.

[0103] The preset voltage value may be determined according to the battery pack voltage. For example, the preset voltage value is the same as the battery pack voltage.

[0104] Exemplarily, the first threshold may be 10V.

[0105] Exemplarily, when the voltage value on the capacitor of the winch module 200 reaches 95% of the preset voltage value, it is determined that the pre-charging of the winch module 200 is completed.

[0106] It can be understood that during the pre-charging process, as the difference between the voltage value corresponding to the preset capacitor of the winch module 200 and the preset voltage value gradually decreases, it means that the winch module 200 gradually enters a stable state. When the voltage difference between the two is closer, the possibility of the winch module 200 being burned out at the moment of connecting to the high-voltage current is lower. Therefore, the present application determines that the pre-charging of the winch module 200 is completed when the difference between the voltage value corresponding to the preset capacitor of the winch module 200 and the preset voltage value is less than or equal to the first threshold.

[0107] In some embodiments, one end of the pre-filling loop 311 is used to connect to the positive output terminal of the energy storage module 100, and the other end of the pre-filling loop 311 is used to connect to the positive input terminal of the winch module 200; or, one end of the pre-filling loop 311 is used to connect to the negative output terminal of the energy storage module 100, and the other end of the pre-filling loop 311 is used to connect to the positive input terminal of the winch module 200.

[0108] It is understandable that the embodiment of the present application does not limit the connection method of the pre-filling circuit 311, making the connection method of the pre-filling circuit 311 more flexible.

[0109] In some embodiments, Figure 2 As shown, the pre-charging module 310 also includes a second power supply circuit 313 .

[0110] Exemplarily, one end of the pre-filling loop 311 is used to connect the positive output terminal of the energy storage module 100, the other end of the pre-filling loop 311 is used to connect the positive input terminal of the winch module 200, one end of the second power supply loop 313 is used to connect the negative output terminal of the energy storage module 100, and the other end of the second power supply loop 313 is used to connect the negative input terminal of the winch module 200; or, one end of the pre-filling loop 311 is used to connect the negative output terminal of the energy storage module 100, the other end of the pre-filling loop 311 is used to connect the negative input terminal of the winch module 200, one end of the second power supply loop 313 is used to connect the positive output terminal of the energy storage module 100, and the other end of the second power supply loop 313 is used to connect the positive input terminal of the winch module 200.

[0111] It is understandable that the winch control system provided in the embodiment of the present application integrates the winch module 200 and the pre-charge control circuit 300, and pre-charges the winch module 200 through the pre-charge control circuit 300. In this way, the possibility of the winch module 200 being burned out at the moment of accessing the high-voltage current can be reduced, thereby improving the safety of the use of the high-voltage electric winch.

[0112] In some embodiments, the pre-charging module 310 is configured to pre-charge the winch module after one or more set circuits connected to the energy storage module 100 complete the discharge operation.

[0113] Exemplarily, the above-mentioned set circuit is a circuit with a higher voltage level, that is, the above-mentioned set circuit can be a high-voltage circuit of the whole vehicle. For example, the voltage of the set circuit refers to a voltage of direct current (DC) above 60V or alternating current (AC) above 25Vrms.

[0114] It can be understood that the discharge operation of the high-voltage circuit refers to releasing the charge in the high-voltage circuit to avoid component damage and electric shock accidents, thereby improving the reliability and safety of the circuit.

[0115] In some embodiments, whether the setting loop has completed the discharge operation is determined based on the voltage between the positive and negative electrodes on the main trunk of the setting loop. For example, when the voltage between the positive and negative electrodes on the main trunk of the setting loop is less than or equal to a preset safety voltage value, it is determined that the setting loop has completed the discharge operation. Exemplarily, the preset safety voltage value may be 60V.

[0116] In some embodiments, Figure 3 As shown, the pre-charging control circuit 300 also includes a power distribution module 320. One end of the power distribution module 320 is used to connect the pre-charging module 310, and the other end of the power distribution module 320 is used to connect the winch module 200. The power distribution module 320 is used to open or close the circuit between the pre-charging module 310 and the winch module 200.

[0117] It can be understood that a power distribution module 320 is set between the pre-charging module 310 and the winch module 200 to connect or disconnect the circuit between the pre-charging module 310 and the winch module 200. In this way, accidental touch can be avoided, which helps to reduce circuit failures and safety accidents caused by incorrect operations.

[0118] In some embodiments, Figure 3 As shown, the power distribution module 320 includes a power distribution switch 321. One end of the power distribution switch 321 is connected to the pre-charging module 310, and the other end of the power distribution switch 321 is used to connect the winch module 200. The power distribution switch 321 is configured to be closed when the winch module 200 is pre-charged.

[0119] It is understandable that the power distribution module 320 includes a power distribution switch 321, which is configured to be closed when precharging the winch module 200, so as to conduct the circuit between the winch module 200 and the precharging module 310. In this way, the reliability and safety of the circuit can be improved, thereby improving driving safety.

[0120] In some embodiments, the power distribution switch 321 includes a positive switch and / or a negative switch. One end of the positive switch is used to connect the positive output end of the pre-charging module 310, and the other end is used to connect the positive input end of the winch module 200; one end of the negative switch is used to connect the negative output end of the pre-charging module 310, and the other end is used to connect the negative input end of the winch module 200.

[0121] In some embodiments, the power distribution switch 321 is one of a relay, a diode, a transistor, a field effect transistor, and a photocoupler.

[0122] In some embodiments, the power distribution module 320 is configured to open the circuit between the pre-charging module 310 and the winch module 200 after one or more set circuits connected to the energy storage module 100 complete the discharge operation.

[0123] In some embodiments, Figure 3 As shown, the pre-charging control circuit 300 further includes a voltage conversion module 330. One end of the voltage conversion module 330 is used to connect to the energy storage module 100 or the pre-charging module 310, and the other end of the voltage conversion module 330 is used to connect to the power supply port of the vehicle.

[0124] Exemplarily, the voltage conversion module 330 may be a direct current-direct current (DC-DC) converter, which may convert high-voltage direct current from the battery pack of the energy storage module 100 into low-voltage direct current to supply power to the low-voltage load of the vehicle.

[0125] In some embodiments, during the discharge operation of the high-voltage circuit of the entire vehicle, the low-voltage power supply remains normal, that is, the DC-DC converter operates normally to provide low-voltage electricity for the vehicle.

[0126] In some embodiments, during the discharge operation of the high-voltage circuit of the vehicle, a 12V battery can also be connected to the power supply port of the vehicle to provide low-voltage electricity to the vehicle.

[0127] In some embodiments, Figure 3 As shown, the pre-charge control circuit 300 further includes a first control module 340. The first control module 340 is connected to the pre-charge module 310, and the first control module 340 is used to control the on and off of the pre-charge module 310.

[0128] It can be understood that the embodiment of the present application can control the on and off of the pre-charging module 310 through the first control module 340, which can accurately control the pre-charging process and improve the reliability and safety of the circuit.

[0129] Exemplarily, the first control module 340 may be a vehicle control unit (VCU).

[0130] Exemplarily, the first control module 340 is used to control the on and off of the pre-filling module 310 , including controlling the first switch module 311 - 2 on the pre-filling circuit 311 of the pre-filling module 310 to close or open, so as to realize the on and off of the pre-filling module 310 .

[0131] Exemplarily, the first control module 340 is configured to: in response to a winch mode start instruction, control the pre-charging module 310 to be turned on to pre-charge the winch module 200 .

[0132] Exemplarily, the first control module 340 is configured to: when it is determined that the pre-charging of the winch module 200 is completed, control the pre-charging module 310 to be disconnected.

[0133] In some embodiments, the first control module 340 is configured to respond to a winch mode start-up instruction and control the pre-charging module 310 to turn on to pre-charge the winch module 200, including: responding to the winch mode start-up instruction, sending a discharge operation instruction, the discharge operation instruction is used to enable one or more set circuits connected to the energy storage module 100 to perform a discharge operation; after the discharge operation is completed, control the pre-charging module 310 to turn on to pre-charge the winch module 200.

[0134] It can be understood that setting the circuit to perform a discharge operation refers to releasing the charge in the set circuit to avoid component damage and electric shock accidents, thereby improving the reliability and safety of the circuit.

[0135] In some embodiments, the first control module 340 determines whether the setting loop has completed the discharge operation based on the voltage between the positive and negative electrodes on the main trunk of the setting loop. For example, when the voltage between the positive and negative electrodes on the main trunk of the setting loop is less than or equal to the preset safety voltage value, it is determined that the setting loop has completed the discharge operation. Exemplarily, the preset safety voltage value may be 60V.

[0136] In some embodiments, after the setting loop completes the discharge operation, the first control module 340 may send a pressure relief completion message to the domain controller of the vehicle to indicate that the setting loop has completed the discharge operation.

[0137] It is understandable that the winch module 200 is usually arranged inside the bumper on the front side of the vehicle. Therefore, for driving safety, when the winch mode is not started, the winch module 200 is not connected to high voltage electricity. When the winch mode is started, the winch module 200 is connected to high voltage electricity. Since the charge energy on the setting circuit is high during the operation of the vehicle, if the winch module 200 is connected at this time, it may cause damage to the components of the winch module 200 or electric shock accidents. Therefore, after receiving the winch mode start instruction, the first control module 340 in the embodiment of the present application first controls the setting circuit to perform the discharge operation, and then after the setting circuit completes the discharge operation, it performs pre-charging and re-applies high voltage. In this way, the reliability and safety of the circuit can be improved.

[0138] In some embodiments, the first control module 340 is further used to conduct the first power supply circuit 312 after the winch module 200 is pre-charged. Exemplarily, the first power supply circuit 312 includes a second switch module 312-1, and the first control module 340 can conduct the first power supply circuit 312 by controlling the second switch module 312-1 to be closed.

[0139] In some embodiments, the first control module 340 is connected to the power distribution module 320 , and the first control module 340 is also used to control the on and off of the power distribution module 320 .

[0140] It can be understood that the embodiment of the present application can control the on and off of the power distribution module 320 through the first control module 340, which can accurately control the pre-charging process and improve the reliability and safety of the circuit.

[0141] Exemplarily, the first control module 340 is further used to control the on and off of the power distribution module 320 , including: the first control module 340 controls the power distribution switch 321 of the power distribution module 320 to be closed or opened to realize the on and off of the power distribution module 320 .

[0142] Exemplarily, the power distribution switch 321 includes a positive switch and / or a negative switch.

[0143] Exemplarily, the first control module 340 is configured to control the power distribution module 320 to close when the winch module 200 is pre-charged, so as to conduct the circuit between the pre-charging module 310 and the winch module 200 .

[0144] In some embodiments, the first control module 340 is configured to: in response to a winch mode start-up instruction, after one or more set circuits connected to the energy storage module 100 complete a discharge operation, control the power distribution module 320 to close so as to conduct the circuit between the pre-charge module 310 and the winch module 200; or, conduct the circuit between the energy storage module 100 and the winch module 200.

[0145] Exemplarily, after determining that the set loop completes the discharge operation, the first control module 340 generates a distribution module closing instruction, and sends the distribution module closing instruction to the winch module 200 through the communication network inside the vehicle (such as the CAN bus); in response to the distribution module closing instruction, the electronic control system in the winch module 200 controls the positive switch and / or the negative switch in the distribution module 320 to close. For example, the electronic control system can send a control instruction to the positive switch and / or the negative switch to perform a closing operation.

[0146] Exemplarily, after determining that the set loop completes the discharge operation, the first control module 340 generates a distribution module closing instruction, and sends the distribution module closing instruction to the distribution module 320 through the communication network inside the vehicle (such as the CAN bus); in response to the distribution module closing instruction, the distribution module 320 controls the positive switch and / or the negative switch to close.

[0147] Exemplarily, after determining that the set loop completes the discharge operation, the first control module 340 generates a distribution module closing instruction, and sends the distribution module closing instruction to the distribution module 320 through the communication network inside the vehicle (such as the CAN bus) to control the positive switch and / or the negative switch to close, so that the positive switch and / or the negative switch are controlled to close in response to the distribution module closing instruction to perform the closing operation.

[0148] Exemplarily, the power distribution module closing instruction may be an electrical signal, such as a voltage signal or a current signal.

[0149] In some embodiments, the first control module 340 is also configured to: in response to the winch mode shut-down instruction, control the power distribution module 320 to disconnect to disconnect the circuit between the pre-charging module 310 and the winch module 200; or, disconnect the circuit between the energy storage module 100 and the winch module 200.

[0150] It is understandable that the winch module 200 is usually arranged inside the bumper on the front side of the vehicle. Therefore, for driving safety, when the winch mode is not started, the winch module 200 is not connected to high voltage electricity. When the winch mode is started, the winch module 200 is connected to high voltage electricity. Therefore, the embodiment of the present application controls the connection and disconnection of the winch module 200 and the high voltage circuit by setting a power distribution switch 321 in the power distribution module 320 and controlling the closing or opening of the power distribution switch 321. In this way, the reliability and safety of the circuit can be improved, thereby improving driving safety.

[0151] In some embodiments, the winch module 200 and the vehicle high voltage circuit share the pre-charging module 310. In this way, the components can be reduced, the pre-charging circuit space can be saved, and the system cost can be optimized on the basis of ensuring the user experience.

[0152] In some embodiments, Figure 4 As shown, the winch control system further includes: a second control module 400, which is in communication connection with the winch module 200, and the second control module 400 is used to send a control instruction to the winch module 200 so that the winch module 200 performs a corresponding operation.

[0153] It is understandable that the second control module 400 can control the winch module 200, for example, control the start, shutdown, speed adjustment and steering adjustment of the winch module 200. In this way, the second control module 400 can achieve accurate control of the winch module 200.

[0154] Exemplarily, the second control module 400 may be a domain controller.

[0155] In some embodiments, the second control module 400 is also responsible for the message interaction between the energy network, the smart entry network and the body network. Among them, the energy network is a network system in the vehicle responsible for energy management and distribution. The energy network can monitor and manage the energy flow and consumption of components such as battery packs, motor controllers, DC-DC converters, etc. in electric vehicles. The smart entry network is a network system in the vehicle responsible for vehicle access control and safety management. Exemplarily, the smart entry network has functions such as keyless entry, identity authentication, and safety monitoring. The body network is a network system in the vehicle responsible for body control and comfort. Exemplarily, the body network has functions such as body control, comfort management, and fault diagnosis.

[0156] In some embodiments, Figure 4 As shown, the winch control system further includes: a terminal module 500. The terminal module 500 is used to output the working information of the winch module 200.

[0157] For example, the terminal module 500 is used to output parameters such as the working state (eg, started or shut down), rotation speed, and direction of the winch module 200 .

[0158] Exemplarily, when the winch module 200 is started, the terminal module 500 can output corresponding icons or text prompts to inform the driver that the winch module 200 is in working state. Similarly, when the winch module 200 is turned off, the terminal module 500 will also update the status information in time.

[0159] Exemplarily, the terminal module 500 can output the rotation speed of the winch module 200 in real time. By monitoring the rotation speed, the driver can better control the working rhythm of the winch to avoid overloading or excessive wear.

[0160] Exemplarily, when the winch module 200 has a bidirectional rotation function, the terminal module 500 can output the direction of the winch module 200 in real time, thereby improving the convenience and accuracy of operation.

[0161] In some embodiments, the terminal module 500 is also used to output the remaining power of the vehicle battery, helping the driver to understand the usable time of the winch module 200 and plan the operation process in advance.

[0162] In some embodiments, when the winch module 200 fails, the terminal module 500 is also used to issue an alarm prompt message and display specific fault information so that the driver can take timely measures to repair it.

[0163] In some embodiments, the terminal module 500 can also be used to display images outside the vehicle, rescue vehicles, vehicle self-rescue, rope retracting and releasing switches, and demonstration images of the winch use process.

[0164] In some embodiments, the terminal module 500 is also used to perform human-computer interaction with a user, for example, to adjust the working parameters of the winch module 200 in response to the user's adjustment operation.

[0165] In some embodiments, the terminal module 500 is further configured to respond to a control operation on the winch module 200 by sending a control instruction corresponding to the control operation to the winch module 200 so that the winch module 200 performs the corresponding operation.

[0166] Exemplarily, the above control operation may be a winch mode start operation, and the control instruction corresponding to the control operation may be a winch mode start instruction.

[0167] Exemplarily, if the above control operation is a winch mode closing operation, the control instruction corresponding to the control operation may be a winch mode closing instruction.

[0168] Exemplarily, the control operation may be a rotation speed adjustment operation of the winch module 200 , and the control instruction corresponding to the control operation may be a rotation speed adjustment instruction of the winch module 200 .

[0169] Exemplarily, the control operation may be a steering adjustment operation of the winch module 200 , and the control instruction corresponding to the control operation may be a steering adjustment instruction of the winch module 200 .

[0170] It is understandable that the user can issue control instructions through the terminal module 500 to achieve remote control of the winch module 200, which is convenient to operate and can improve the user experience.

[0171] Exemplarily, the terminal module 500 may include a display screen, such as a flat panel display device (Panel Display Device, PAD) or a display touch screen.

[0172] The terminal module 500 can display the working information of the winch module 200 on the display screen, and / or the terminal module 500 can perform human-computer interaction with the user through the display screen, for example, receive the user's control operation on the winch module 200 through the display screen.

[0173] It is understandable that the working information of the winch module is output through the terminal module, and / or the control operation for the winch module is received; in this way, the user can promptly know the working status of the winch module, and realize precise control of the winch module through human-computer interaction with the user.

[0174] In some embodiments, Figure 4 As shown, the second control module 400 is connected to the terminal module 500, and the terminal module 500 can send a control instruction corresponding to the control operation to the winch module 200 through the second control module 400, so that the winch module 200 performs the corresponding operation.

[0175] Exemplarily, the terminal module 500 sends a control instruction corresponding to the control operation to the second control module 400 , the second control module 400 receives the control instruction sent by the terminal module 500 , and sends the control instruction to the winch module 200 .

[0176] It is understandable that the second control module 400 can control the winch module 200 based on the control instruction corresponding to the control operation sent by the terminal module 500.

[0177] Exemplarily, in response to a user's control operation, the control instruction issued by the terminal module 500 may be a winch mode start instruction, and the second control module 400 may send the winch mode start instruction to the winch module 200 to start the winch module 200 .

[0178] Exemplarily, in response to the user's control operation, the control instruction issued by the terminal module 500 may be a winch mode closing instruction, and the second control module 400 may send the winch mode closing instruction to the winch module 200 to close the winch module 200.

[0179] Exemplarily, in response to a user's control operation, the control instruction issued by the terminal module 500 may be a speed adjustment instruction for the winch module 200 , and the second control module 400 may send the speed adjustment instruction to the winch module 200 to adjust the speed of the winch module 200 .

[0180] Exemplarily, in response to a user's control operation, the control instruction issued by the terminal module 500 may be a steering adjustment instruction of the winch module 200 , and the second control module 400 may send the steering adjustment instruction to the winch module 200 to adjust the steering of the winch module 200 .

[0181] In some embodiments, the second control module 400 and the first control module 340 in the pre-charge control circuit 300 can be connected through the vehicle's communication network (e.g., CAN bus), and the second control module 400 can also send the control instruction received from the terminal module 500 to the first control module 340. Exemplarily, when the second control module 400 receives a winch mode start instruction from the terminal module 500, the winch mode start instruction can be sent to the first control module 340. When the second control module 400 receives a winch mode shutdown instruction from the terminal module 500, the winch mode shutdown instruction can be sent to the first control module 340.

[0182] The present application also provides a winch control method, which is applied to the pre-charge control circuit in the winch control system. Figure 5 As shown, the winch control method provided in the embodiment of the present application includes the following steps.

[0183] S801. In response to a winch mode start instruction, control a pre-charging module to pre-charge a winch module.

[0184] The capstan mode start instruction may be a capstan mode start instruction issued by the terminal module in response to a capstan mode start operation input by a user in the terminal module. Exemplarily, the terminal module is connected to the second control module, and the capstan mode start instruction may be sent by the terminal module to the second control module, and then sent by the second control module to the first control module in the prediction control circuit.

[0185] In some embodiments, the pre-charging module includes a pre-charging circuit, wherein one end of the pre-charging circuit is used to connect to the energy storage module, and the other end of the pre-charging circuit is used to connect to the winch module. Then the above step S801 can be implemented as follows: in response to the winch start instruction, the pre-charging circuit is controlled to be turned on to pre-charge the winch module.

[0186] Among them, the pre-charging circuit of the pre-charging module includes a first switch module, and the above-mentioned control of the pre-charging circuit to be turned on includes: responding to the winch mode start instruction, controlling the first switch module on the pre-charging circuit to close, so that the pre-charging circuit is turned on.

[0187] In some embodiments, the winch module is a high voltage winch module.

[0188] In some embodiments, the high-voltage winch module includes a capacitor, and the above step S801 can be implemented as: controlling the pre-charging circuit to be turned on to pre-charge the capacitor in the high-voltage winch module.

[0189] It is understandable that the winch control method provided in the embodiment of the present application can pre-charge the winch module by controlling the pre-charging module. In this way, the possibility of the winch module being burned out at the moment of accessing the high-voltage current can be reduced, and the safety of the high-voltage electric winch can be improved.

[0190] In some embodiments, Figure 6 As shown, the above step S801 can be implemented as the following steps:

[0191] S8011. In response to the winch mode start instruction, send a discharge operation instruction.

[0192] The discharge operation instruction is used to enable one or more set circuits connected to the energy storage module to perform a discharge operation.

[0193] Exemplarily, the discharge operation instruction is sent by the first control module to the device in the setting loop; accordingly, after receiving the discharge operation instruction, the device in the setting loop performs the discharge operation.

[0194] It can be understood that setting the circuit to perform a discharge operation refers to releasing the charge in the set circuit to avoid component damage and electric shock accidents, thereby improving the reliability and safety of the circuit.

[0195] S8012: After the discharge operation is completed, the pre-charging module is controlled to be turned on to pre-charge the winch module.

[0196] In some embodiments, whether the setting loop has completed the discharge operation is determined based on the voltage between the positive and negative electrodes on the main trunk of the setting loop. For example, when the voltage between the positive and negative electrodes on the main trunk of the setting loop is less than or equal to a preset safety voltage value, it is determined that the setting loop has completed the discharge operation. Exemplarily, the preset safety voltage value may be 60V.

[0197] It is understandable that the winch module is usually arranged inside the bumper on the front side of the vehicle. Therefore, for driving safety, when the winch mode is not started, the winch module is not connected to high voltage electricity. When the winch mode is started, the winch module is connected to high voltage electricity. Since the charge energy on the setting circuit is high during the operation of the vehicle, if the winch module is connected at this time, it may cause damage to the components of the winch module or electric shock accidents. Therefore, after receiving the winch mode start instruction, the first control module in the embodiment of the present application first controls the setting circuit to perform the discharge operation, and then after the setting circuit completes the discharge operation, it performs pre-charging and re-applies high voltage. In this way, the reliability and safety of the circuit can be improved.

[0198] In some embodiments, the pre-charging control circuit further includes a power distribution module. One end of the power distribution module is used to connect the pre-charging module, and the other end of the power distribution module is used to connect the winch module. The power distribution module is used to connect or disconnect the circuit between the pre-charging module and the winch module.

[0199] In some embodiments, the above method also includes: controlling the on and off of the power distribution module.

[0200] Exemplarily, the power distribution module includes a power distribution switch. One end of the power distribution switch is connected to the pre-charging module, and the other end of the power distribution switch is used to connect the winch module. Then the above-mentioned control of the power distribution module on and off can be realized by controlling the closing or opening of the power distribution switch to realize the control of the power distribution module on and off.

[0201] Exemplarily, the power distribution switch includes a positive switch and / or a negative switch.

[0202] In some embodiments, the above-mentioned control of the power distribution module on and off includes: when the winch module is pre-charged, controlling the power distribution module to close to conduct the circuit between the pre-charging module and the winch module.

[0203] In some embodiments, the above-mentioned control of the on and off of the power distribution module includes: responding to the winch mode start instruction, after one or more set circuits connected to the energy storage module complete the discharge operation, controlling the power distribution module to close to conduct the circuit between the pre-charge module and the winch module; or, conducting the circuit between the energy storage module and the winch module.

[0204] In some embodiments, the above-mentioned control of the power distribution module on and off includes: in response to the winch mode shutdown instruction, controlling the power distribution module to disconnect to disconnect the circuit between the pre-charging module and the winch module; or, disconnecting the circuit between the energy storage module and the winch module.

[0205] It is understandable that for driving safety, when the winch mode is not started, the winch module is not connected to high voltage power, and the power distribution switch is disconnected; when the winch mode is started, the power distribution switch is controlled to close to conduct the circuit between the energy storage module and the winch module, so that the winch module is connected to the high voltage circuit. In this way, the reliability and safety of the circuit can be improved, thereby improving driving safety.

[0206] In some embodiments, after the above step S801, the above method further includes: after the pre-charging of the winch module is completed, controlling the pre-charging circuit to disconnect.

[0207] The above-mentioned controlling the pre-charging circuit to be disconnected may be realized by: controlling the first switch module on the pre-charging circuit to be disconnected.

[0208] In some embodiments, when the difference between the voltage value corresponding to the preset capacitance of the winch module and the preset voltage value is less than or equal to the first threshold, the pre-charging of the winch module is completed.

[0209] The preset voltage value may be determined according to the battery pack voltage. For example, the preset voltage value is the same as the battery pack voltage.

[0210] Exemplarily, the first threshold may be 10V.

[0211] Exemplarily, when the voltage value on the capacitor of the winch module 200 reaches 95% of the preset voltage value, it is determined that the pre-charging of the winch module 200 is completed.

[0212] In some embodiments, after the above step S801, the above method further includes: after the winch module is pre-charged, controlling the first power supply circuit to be turned on. Exemplarily, the first power supply circuit includes a second switch module, and the above control of the first power supply circuit to be turned on can be implemented as: controlling the second switch module to be closed to turn on the first power supply circuit.

[0213] In summary, based on the winch control method provided in the embodiment of the present application, the winch module and the pre-charging control circuit are integrated, and the winch module is pre-charged through the pre-charging module of the vehicle. In this way, the possibility of the winch module being burned out at the moment of access to the high-voltage current can be reduced, and the safety of the use of the high-voltage electric winch can be improved. At the same time, the winch module and the high-voltage circuit of the vehicle share the pre-charging module, which can reduce parts, save pre-charging circuit space, and optimize system costs while ensuring user experience. At the same time, when the embodiment of the present application receives the winch mode start command, the high voltage is first lowered on the whole vehicle, and then the pre-charging module is used for pre-charging, and then the high voltage operation is performed on the whole vehicle, which can improve the reliability and safety of the circuit, thereby improving driving safety.

[0214] Next, in conjunction with the winch control system provided in the above embodiment, the operation flow of the winch control system entering the winch mode is described.

[0215] For example, Figure 7 As shown, the operation flow of the winch control system entering the winch mode includes the following steps:

[0216] S901. The terminal module sends a winch mode start instruction to the second control module in response to a winch mode start operation.

[0217] S902. The second control module receives the winch mode start instruction sent by the terminal module, and sends the winch mode start instruction to the winch module.

[0218] S903: The second control module sends a winch mode start instruction to the first control module.

[0219] S904: The first control module sends a discharge operation instruction in response to the winch mode start instruction, where the discharge operation instruction is used to enable one or more set circuits connected to the energy storage module to perform a discharge operation.

[0220] S905: After the discharge operation is completed, the first control module controls the pre-charging circuit of the pre-charging module to be turned on to pre-charge the winch module.

[0221] S906: After the discharge operation is completed, the first control module controls the power distribution module to conduct the circuit between the energy storage module and the winch module.

[0222] Exemplarily, the first control module controls the power distribution switch in the power distribution module to close so as to conduct the circuit between the energy storage module and the winch module.

[0223] It should be noted that the embodiment of the present application does not limit the execution order of the above 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 step S905 and step S906 can be executed at the same time.

[0224] S907: The pre-charging module pre-charges the winch module.

[0225] S908: After the winch module is pre-charged, the first control module controls the pre-charging circuit of the pre-charging module to be disconnected.

[0226] Exemplarily, the first control module determines that the pre-charging of the winch module is completed when it detects that the voltage in the winch module is close to a preset voltage value (eg, the battery pack voltage).

[0227] S909: The first control module controls the first power supply circuit to be turned on.

[0228] The first power supply circuit includes a second switch module, and the first control module controls the second switch module to close, thereby making the first power supply circuit conductive.

[0229] It is understandable that when the vehicle is ready to be powered by high voltage, the first control module will first control the pre-charging circuit to work and perform pre-charging. This process can gradually increase the voltage across the capacitor to prevent excessive surge current when the second switch module is closed. After the pre-charging is completed, the first control module will control the second switch module to close, at which time the first power supply circuit is turned on, and the vehicle's high-voltage equipment is officially connected to the circuit.

[0230] S910. Power on the first control module again and confirm that the display status on the instrument panel is normal.

[0231] For example, if "OK" or "READY" is displayed on the instrument panel, it means that the vehicle has been successfully powered on to high voltage.

[0232] S911, winch module starts working.

[0233] S912. During the operation of the winch module, the terminal module may display the operating parameters of the winch module.

[0234] Exemplarily, the terminal module is also used to perform human-computer interaction with a user, for example, to adjust the working parameters of the winch module in response to the user's adjustment operation.

[0235] Exemplarily, the terminal module is further configured to send a control instruction corresponding to the input operation to the winch module in response to the input operation.

[0236] In summary, based on the winch control system provided in the embodiment of the present application, the winch module and the pre-charging circuit module can be integrated, and the winch module can be pre-charged through the pre-charging circuit module of the vehicle. In this way, the possibility of the winch module being burned out at the moment of accessing the high-voltage current can be reduced, and the safety of the use of the high-voltage electric winch can be improved. At the same time, the winch module and the high-voltage circuit of the vehicle share a pre-charging module, which can reduce parts, save pre-charging circuit space, and optimize system costs on the basis of ensuring user experience. At the same time, by controlling the closing or disconnection of the distribution switch of the distribution module to control the connection and disconnection of the winch module and the high-voltage circuit, the reliability and safety of the circuit can be improved, thereby improving driving safety. Based on the operation process of the winch control system provided in the embodiment of the present application to enter the winch mode, when the winch mode start command is received, the high-voltage discharge operation is first performed, and then the high-voltage operation on the whole vehicle is performed after pre-charging through the pre-charging module, so that the reliability and safety of the circuit can be improved, thereby improving driving safety.
