Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and in particular to a winch control method, device, electronic device and storage medium. Background Technology
[0002] A winch is a tool that converts the power of a winch motor into the tension of a cable, using a steel rope or special cable fixed or pulled at the other end of the cable to pull a vehicle out of trouble. When a vehicle is traveling in harsh road conditions, such as gravel roads, deserts, mudflats, snow, or other complex terrains, a winch installed on the vehicle can enable self-rescue or assist in rescuing other stranded vehicles. Currently, winches are usually retrofitted; for electric vehicles, the retrofitted winch is powered by the vehicle's low-voltage power supply system.
[0003] However, when the winch motor is running under high load, it may cause the DC-to-DC converter to shut down. At this time, the low-voltage power supply system needs to be maintained through the low-voltage battery, which will further lead to the low-voltage battery being depleted, thus making the vehicle unable to start.

[0013] If the output power is detected to be greater than or equal to a preset first power threshold, it is then detected whether the output power is less than a preset second power threshold.
[0014] If the output power is detected to be less than a preset second power threshold, the comfort function of the electric vehicle is turned off and the winch is kept open.
[0015] Optionally, the electric vehicle includes a low-voltage battery, the energy consumption data includes the remaining power of the low-voltage battery, and the preset energy consumption parameter includes a preset power threshold.
[0016] After the step of detecting whether the output power is less than a preset second power threshold, the method further includes:
[0017] If the output power is detected to be greater than or equal to a preset second power threshold, the DC-DC converter is turned off.
[0018] Detect whether the remaining battery power is greater than a preset battery power threshold;
[0019] If the remaining power is less than or equal to a preset power threshold, the winch is turned off.
[0020] Optionally, the step of detecting whether the remaining battery power is greater than a preset battery power threshold includes:
[0021] Start timing and check if the remaining battery power is greater than a preset battery power threshold;
[0022] After the step of detecting whether the remaining power is greater than a preset power threshold, the method further includes:
[0023] If the remaining battery power is detected to be greater than a preset battery power threshold and the time exceeds a preset first time threshold, the DC-DC converter is activated, and the process returns to the step of detecting the energy consumption data of the electric vehicle.
[0024] Optionally, the step of turning off the winch when the remaining power is less than or equal to a preset power threshold includes:
[0025] Get the number of short-term counts;
[0026] If the number of short-term timings exceeds a preset threshold, monitor whether the timing exceeds a preset second time threshold, wherein the preset second time threshold is greater than the preset first time threshold;
[0027] If the remaining power is detected to be less than or equal to a preset power threshold, or if the timer exceeds a preset second time threshold, the winch is turned off.
[0028] Optionally, the winch control method further includes the following steps:
[0029] When the DC-DC converter of the electric vehicle is in the off state, the speed of the electric vehicle is controlled to be less than a preset speed threshold.
[0030] Optionally, before the step of detecting the energy consumption data of the electric vehicle when the winch is in the open state, the method further includes:
[0031] In response to the operation command to start the winch, high-voltage power supply status information is obtained;
[0032] If the high-voltage power supply status information indicates that the high-voltage power system of the electric vehicle is powered on and fault-free, the winch is activated.

By detecting the energy consumption data of the electric vehicle when the winch is in the open state, it achieves monitoring of the electric vehicle's energy consumption data during winch operation. Furthermore, by controlling the winch's operating state based on the energy consumption data and preset energy consumption parameters, it achieves winch control adapted to the vehicle's energy consumption situation. Since energy consumption data reflects the current energy consumption of the entire vehicle, controlling the winch's operating state in conjunction with the current energy consumption of the vehicle allows for timely control of the winch's operating state even when the vehicle's energy consumption is high. This effectively avoids overloading the low-voltage power supply system due to winch operation, thereby reducing the risk of DC-DC shutdown and low-voltage battery depletion. It overcomes the technical defect that high load operation of the winch motor may cause DC-DC shutdown, requiring the low-voltage power supply system to operate through the low-voltage battery, which could further lead to low-voltage battery depletion and prevent the vehicle from starting. This reduces the failure rate during winch use on electric vehicles and improves the user experience. Attached Figure Description

[0046] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0047] Example 1
[0048] This application provides a winch control method. In the first embodiment of the winch control method of this application, refer to... Figure 1 The winch control method is applied to electric vehicles and includes the following steps:
[0049] Step S10: With the winch in the open state, detect the energy consumption data of the electric vehicle;
[0050] The execution subject of the method in this embodiment can be a winch control device, a winch control terminal device, or a server. This embodiment takes a winch control device as an example. The winch control device can be integrated into terminal devices such as vehicles with data processing functions, vehicle controllers, vehicle terminals, smartphones, and tablets.
[0051] In this embodiment, it should be noted that the winch control method is applied to an electric vehicle, which can be a pure electric vehicle or a hybrid vehicle. The power supply system of the electric vehicle includes at least a high-voltage power supply system, a low-voltage power supply system, a DC-DC converter, and a winch. The DC-DC converter converts the high-voltage DC power in the high-voltage power supply system into low-voltage DC power to supply power to the low-voltage power supply system. The winch is powered by the low-voltage power supply system. However, the power of the winch is usually high. When the winch motor operates under high load, causing the DC-DC converter to be overloaded, the DC-DC converter's overload protection will be triggered. When the winch motor operates beyond the DC-DC converter's load, it will cause the DC-DC converter to shut down irreversibly. After the DC-DC converter shuts down, the low-voltage power supply system is powered by the low-voltage battery. The low-voltage battery has a limited capacity. If the low-voltage battery continues to supply power, it is easy for it to run out of power, resulting in the inability to start normally, causing vehicle malfunction, and greatly affecting the user experience.
[0052] The operating state of the winch includes at least one of the following: on, off, and gear position. When the winch is powered on, it is in the on state; when the winch is powered off, it is in the off state. The winch may also be equipped with different gear positions, each with different power outputs. The operating state can also be represented by a gear position; for example, if the winch is equipped with a high gear, a medium gear, and a low gear, the operating state of the winch may include a high gear state, a medium gear state, and a low gear state.
[0053] The energy consumption data refers to data related to the electric vehicle's electrical energy consumption, including the power of various electrical appliances, the output power of the DC-DC converter, and the battery charge. The energy consumption data can reflect the current electrical energy consumption of the electric vehicle. By controlling the winch's operating status in conjunction with the current electrical energy consumption of the entire vehicle, the operating status of the winch can be controlled in a timely manner when the vehicle's energy consumption is high. For example, the winch can be turned off in time or its operating power can be reduced. Other energy consumption management measures can also be taken in a timely manner, such as reducing the power consumption of other electrical appliances in the vehicle's low-voltage power supply system or temporarily turning off the winch. This can prevent the low-voltage power supply system from being overloaded due to the operation of the winch and reduce the risk of DC-DC converter shutdown and low-voltage battery depletion.
[0054] For example, step S10 includes: after the winch is powered on, when the winch is in the open state, the energy consumption data of the electric vehicle can be continuously or periodically detected by the vehicle controller to determine the energy consumption of the vehicle in a timely manner.
[0055] Optionally, before the step of detecting the energy consumption data of the electric vehicle when the winch is in the open state, the method further includes:
[0056] Step A10: In response to the operation command to start the winch, obtain high-voltage power supply status information;
[0057] Step A20: If it is determined from the high-voltage power supply status information that the high-voltage power system of the electric vehicle is powered on and without fault, control the winch to start.
[0058] In this embodiment, it should be noted that the high-voltage power supply status information refers to the status information of the high-voltage power supply system of the electric vehicle, including operating status, fault status, etc.
[0059] For example, steps A10-A20 include: after detecting the operation command to turn on the winch, first obtaining the high-voltage power supply status information of the electric vehicle, determining whether the high-voltage power supply system of the electric vehicle is in a powered-on state and without fault based on the high-voltage power supply status information, and controlling the winch to turn on if it is determined that the high-voltage power supply system of the electric vehicle is in a powered-on state and without fault.
[0060] In one feasible approach, the vehicle controller can output a signal to the winch's ACC signal acquisition port as an enable signal to control the winch motor's functional state. The vehicle controller determines whether the electric vehicle's high-voltage power supply system is powered on and fault-free, and then outputs an enable signal to allow the winch to start.
[0061] In this embodiment, when the high-voltage power supply system is powered on and fault-free, the DC-DC converter can normally convert the high-voltage DC power of the high-voltage power supply system into low-voltage DC power. Therefore, controlling the winch to start when the high-voltage power supply system is operating normally can effectively avoid the situation where the battery is depleted due to directly powering the winch through the battery.
[0062] Step S20: Control the operating status of the winch based on the energy consumption data and preset energy consumption parameters.
[0063] In this embodiment, the preset energy consumption parameters refer to the parameters corresponding to each of the energy consumption data that are set in advance. They can be set according to the actual needs of various energy consumption data or the results of actual vehicle calibration, etc. For example, they can be the limits that each energy consumption data may cause a fault, or the limits that each energy consumption data may cause some or all of the vehicle's functions to malfunction. This embodiment does not impose any restrictions on this.
[0064] For example, step S20 includes: controlling the operating state of the winch according to the numerical relationship between the energy consumption data and the preset energy consumption parameters, wherein the method of controlling the operating state of the winch includes maintaining the existing operating state or switching the operating state.
[0065] Optionally, the electric vehicle includes a DC-DC converter, the energy consumption data includes the output power of the DC-DC converter, and the preset energy consumption parameter includes a preset first power threshold.
[0066] The step of controlling the operating status of the winch based on the energy consumption data and preset energy consumption parameters includes:
[0067] Step S21: When the output power is detected to be greater than or equal to a preset first power threshold, the operating status of the winch is controlled according to the energy consumption data and preset energy consumption parameters, and the energy consumption of the low-voltage power system of the electric vehicle is managed according to the energy consumption data and preset energy consumption parameters.
[0068] In this embodiment, it should be noted that the electric vehicle includes a DC-DC converter, the energy consumption data includes the output power of the DC-DC converter, and the preset energy consumption parameter includes a preset first power threshold. The preset first power threshold can be determined according to actual needs or vehicle calibration results, etc., and this embodiment does not impose any restrictions on it.
[0069] For example, step S21 includes: after detecting the output power of the DC-DC converter in the electric vehicle, comparing the output power with a preset first power threshold to determine whether the output power is greater than or equal to the preset first power threshold. If the output power is detected to be greater than or equal to the preset first power threshold, controlling the operation of the winch according to the numerical relationship between the energy consumption data and preset energy consumption parameters, and managing the energy consumption of the low-voltage electrical system of the electric vehicle according to the numerical relationship between the energy consumption data and preset energy consumption parameters. The energy consumption management of the low-voltage electrical system of the electric vehicle includes shutting down some low-voltage electrical equipment in the low-voltage electrical system, reducing the power of some or all low-voltage electrical equipment in the low-voltage electrical system, etc., to reduce the output power of the DC-DC converter and reduce the risk of the DC-DC converter shutting down due to overload.
[0070] When managing the energy consumption of the low-voltage electrical system of the electric vehicle, the output power of the DC-DC converter may be reduced to a lower risk level or may remain high. Therefore, the existing operating state of the winch may be maintained temporarily, or the operating state of the winch may be switched. The specific choice can be made based on the energy consumption data and preset energy consumption parameters.
[0071] In this embodiment, if the output power is detected to be greater than or equal to a preset first power threshold, it indicates that the energy consumption of the current vehicle's low-voltage electrical system is high, the load on the DC-DC converter is large, and the risk of the DC-DC converter shutting down is high. Therefore, by managing the energy consumption of the low-voltage electrical system of the electric vehicle, the output power of the DC-DC converter can be reduced, thereby reducing the risk of the DC-DC converter shutting down when the output power of the DC-DC converter is overloaded.
[0072] Optionally, the preset energy consumption parameter includes a preset second power threshold, wherein the preset second power threshold is greater than the preset first power threshold;
[0073] The steps of controlling the operation of the winch based on the energy consumption data and preset energy consumption parameters when the output power is detected to be greater than or equal to a preset first power threshold, and managing the energy consumption of the low-voltage power system of the electric vehicle based on the energy consumption data and preset energy consumption parameters, include:
[0074] Step S211: If the output power is detected to be greater than or equal to a preset first power threshold, then detect whether the output power is less than a preset second power threshold.
[0075] Step S212: If the output power is detected to be less than a preset second power threshold, the comfort function of the electric vehicle is turned off and the winch is kept open.
[0076] In this embodiment, it should be noted that the preset energy consumption parameter includes a preset second power threshold, wherein the preset second power threshold is greater than the preset first power threshold. That is, a lower first power threshold and a higher second power threshold can be set. When the output power is greater than or equal to the preset first power threshold but less than the preset second power threshold, the winch does not need to be turned off first; instead, the comfort functions of the electric vehicle can be turned off first. The comfort functions include at least one of air conditioning, seat ventilation, seat heating, wireless charging for mobile phones, and seat massage, etc. The specific settings can be adjusted according to the actual situation, and this embodiment does not impose any restrictions on this. Since the winch is usually used in special circumstances where the vehicle is in trouble, the use of the winch has a higher priority than the comfort functions when the vehicle is in trouble. Therefore, disconnecting the comfort load control relay limits the power consumption of the comfort load to ensure the normal use of the winch. When the output power is greater than or equal to the preset second power threshold, the output power of the DC-DC converter is close to full load. If the low-voltage power system experiences a short-term power surge, the risk of the DC-DC converter shutting down is high. Therefore, the DC-DC converter can be actively shut down or the winch can be turned off to avoid the DC-DC converter from being overloaded and causing an irreversible shutdown.
[0077] For example, steps S211-S212 include: after detecting the output power of the DC-DC converter in the electric vehicle, comparing the output power with a preset first power threshold to determine whether the output power is greater than or equal to the preset first power threshold. If the output power is greater than or equal to the preset first power threshold, comparing the output power with a preset second power threshold to determine whether the output power is less than the preset second power threshold. If the output power is less than the preset second power threshold, disconnecting the comfort load control relay to stop the use of the comfort function of the electric vehicle and keeping the winch open. If the output power is greater than or equal to the preset second power threshold, the DC-DC converter can be actively shut down or the winch enable output can be disconnected, and the winch can be turned off, etc., to promptly avoid the DC-DC converter from shutting down under full load.
[0078] Optionally, the electric vehicle includes a low-voltage battery, the energy consumption data includes the remaining power of the low-voltage battery, and the preset energy consumption parameter includes a preset power threshold.
[0079] After the step of detecting whether the output power is less than a preset second power threshold, the method further includes:
[0080] Step S213: If the output power is detected to be greater than or equal to a preset second power threshold, the DC-DC converter is turned off.
[0081] Step S214: Detect whether the remaining power is greater than a preset power threshold;
[0082] Step S215: If the remaining power is less than or equal to a preset power threshold, turn off the winch.
[0083] In this embodiment, it should be noted that the electric vehicle may also include a low-voltage battery. This low-voltage battery can supply power to the low-voltage electrical system of the electric vehicle after the DC-DC converter is turned off. However, the low-voltage battery has a limited capacity and is typically only for emergency use. If the low-voltage battery is depleted and the DC-DC converter is still not functioning properly, the vehicle cannot start. Therefore, even when the vehicle is in trouble, the normal operation of the vehicle takes priority over the use of the winch. Thus, it is necessary to ensure that the low-voltage battery has a certain amount of remaining charge. Therefore, a charge threshold can be pre-set based on actual conditions or vehicle calibration results to prevent the winch from depleting the low-voltage battery below the charge threshold, thereby preventing the winch's use from affecting the normal starting of the vehicle.
[0084] For example, steps S213-S215 include: when the output power is detected to be greater than or equal to a preset second power threshold, turning off the DC-DC converter to avoid an irreversible shutdown due to full load of the DC-DC converter; then detecting the remaining power of the low-voltage battery, comparing the remaining power with the value of a preset power threshold, and determining whether the remaining power is greater than the preset power threshold; if the remaining power is detected to be greater than the preset power threshold, the winch can continue to be powered by the low-voltage battery without turning it off, or the step of detecting whether the remaining power is greater than the preset power threshold can be returned to continuously monitor the remaining power of the low-voltage battery; if the remaining power is less than or equal to the preset power threshold, turning off the winch to ensure that the vehicle can start.
[0085] Optionally, the winch control method further includes the following steps:
[0086] When the DC-DC converter of the electric vehicle is in the off state, the speed of the electric vehicle is controlled to be less than a preset speed threshold.
[0087] In this embodiment, it should be noted that the winch on the vehicle primarily serves two functions: getting out of trouble and clearing road obstacles. When using the winch to get out of trouble, the vehicle typically needs to maintain a certain speed to provide power together with the winch to complete the extrication. However, during the extrication process, in order to provide sufficient power, the vehicle may not be able to reduce the power in time after getting out of trouble, resulting in excessive speed and potentially causing an accident. For example, when a vehicle is stuck in mud, the driver may accelerate to get out. When the wheels emerge from the mud, it is a sudden event for the driver, and there may not be enough time to immediately release the accelerator or apply the brakes. However, the resistance of the mud has decreased, so the vehicle speed will suddenly increase, potentially causing a safety accident. Therefore, the vehicle speed can be limited to ensure the safety of the entire vehicle.
[0088] For example, when the DC-DC converter of the electric vehicle is in the off state, the speed of the electric vehicle is limited so that the speed of the electric vehicle is less than a preset speed threshold.
[0089] In this embodiment, by detecting the energy consumption data of the electric vehicle while the winch is in the open state, the energy consumption data of the electric vehicle is monitored during the winch's operation. Then, by controlling the winch's operating state based on the energy consumption data and preset energy consumption parameters, the winch's control is adapted to the vehicle's energy consumption. Since the energy consumption data reflects the vehicle's current energy consumption, controlling the winch's operating state in conjunction with the vehicle's current energy consumption allows for timely control of the winch's operating state even when the vehicle's energy consumption is high. This effectively avoids overloading the low-voltage power supply system due to winch operation, thereby reducing the risk of DC-DC shutdown and low-voltage battery depletion. It overcomes the technical defect that high load operation of the winch motor may cause DC-DC shutdown, requiring the low-voltage battery to maintain the low-voltage power supply system, which could further lead to low-voltage battery depletion and prevent the vehicle from starting. This reduces the failure rate during winch use on electric vehicles and improves the user experience.
[0090] Example 2
[0091] Furthermore, referring to Figure 2 Based on the above embodiments of this application, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, the step of detecting whether the remaining power is greater than a preset power threshold includes:
[0092] Step B10: Start timing and check whether the remaining battery power is greater than a preset battery power threshold;
[0093] In this embodiment, it should be noted that during the use of the winch, a power surge may occur due to usage needs or circuit instability. However, the power surge is usually intermittent or short-lived. Therefore, when the output power of the DC-DC converter is greater than or equal to the preset second power threshold, it can be temporarily shut down to avoid the power surge affecting the DC-DC converter. After the power stabilizes or decreases, the DC-DC converter can be turned on to continue supplying power. This avoids the inconvenience caused by only being able to use the converter for a short period of time with a small amount of power from the low-voltage battery after the DC-DC converter is irreversibly shut down, thus improving the user experience and effectively preventing the low-voltage battery from running out of power.
[0094] For example, step B10 includes: immediately starting a timer after the DC-DC converter is turned off, and continuously detecting whether the remaining power of the low-voltage battery is greater than a preset power threshold.
[0095] After the step of detecting whether the remaining power is greater than a preset power threshold, the method further includes:
[0096] Step B20: If the remaining power is detected to be greater than a preset power threshold and the time exceeds a preset first time threshold, the DC-DC converter is turned on, and the process returns to the step of detecting the energy consumption data of the electric vehicle.
[0097] For example, step B20 includes: when the timer is detected to exceed a preset first time threshold, even if the remaining power is greater than a preset power threshold, the DC-DC converter is turned on to supply power to the low-voltage power system via DCDC, and the process returns to the step of detecting the energy consumption data of the electric vehicle, continuously monitoring the energy consumption data of the electric vehicle.
[0098] Optionally, the step of turning off the winch when the remaining power is less than or equal to a preset power threshold includes:
[0099] Step S2151: Obtain the number of short-time counts;
[0100] Step S2152: If the number of short-time counts exceeds a preset count threshold, monitor whether the count exceeds a preset second time threshold, wherein the preset second time threshold is greater than the preset first time threshold;
[0101] Step S2153: If the remaining power is detected to be less than or equal to a preset power threshold, or if the time exceeds a preset second time threshold, the winch is turned off.
[0102] In this embodiment, it should be noted that frequent switching of the DC-DC converter can affect its lifespan. Therefore, after multiple short-term shutdowns, if the DC-DC output power remains high, greater than or equal to a preset second power threshold, the DC-DC converter needs to be shut off for an extended period. The winch will then be powered by a low-voltage battery for a period of time, allowing the user to quickly escape the predicament or devise other solutions during this period. The preset second time threshold is greater than the preset first time threshold, and can be determined in advance based on actual conditions or vehicle calibration results; this embodiment does not impose any limitations on this.
[0103] For example, steps S2151-S2153 include: immediately starting a timer after turning off the DC-DC converter and acquiring a short-term timer count; determining whether to perform short-term or long-term timer based on the short-term timer count. If the short-term timer count does not exceed a preset threshold, short-term timer is performed, and the step of turning on the DC-DC converter when the remaining battery power is detected to be greater than a preset battery power threshold and the timer exceeds a preset first time threshold is executed. If the short-term timer count exceeds the preset threshold, long-term timer is performed, and the timer is monitored to see if it exceeds a preset second time threshold. After turning off the DC-DC converter, if the remaining battery power is detected to be less than or equal to the preset battery power threshold, or the timer exceeds the preset second time threshold, the winch is turned off.
[0104] In this embodiment, by shutting down the DC-DC converter for a period of time, the DC-DC converter can avoid short-term low-voltage power system instability or high-power use of the winch. After this period of power surge, restarting the DC-DC converter can effectively prevent battery depletion.
[0105] Example 3
[0106] Furthermore, embodiments of this application also provide a winch control device, referring to... Figure 3 The winch control device is used in electric vehicles and includes:
[0107] The acquisition module 10 is used to detect the energy consumption data of the electric vehicle when the winch is in the open state.
