DETAILED DESCRIPTION

[0019] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0020] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The main solutions of the embodiments of the present application are: obtaining the current state parameters of the vehicle; when the current state parameters meet the parameter requirements, activating the low-temperature anti-breakdown function and obtaining the power generation control strategy according to the current state parameters and the preset parameter thresholds; controlling the vehicle's driving state based on the power generation control strategy; adjusting the vehicle's engine power generation according to the vehicle's driving state to prevent the vehicle from breaking down.

[0022] In this embodiment, for the convenience of description, the following description is made by taking the identification of the vehicle low-temperature anti-anchoring equipment as the execution subject.

[0023] Due to the existing technology, more and more fuel cell vehicles are currently used for travel, urban logistics, and urban transportation. Fuel cell vehicles include hydrogen fuel cell vehicles, and the energy of their batteries is generated by the electrochemical reaction of hydrogen and oxygen, which is 1.5 times the efficiency of ordinary internal combustion engines. However, the hydrogen fuel cell vehicle needs to be heated before starting in a low-temperature environment. However, the existing fuel cell vehicles generally take a long time to start in a low-temperature environment. In an extremely low-temperature environment, when a hybrid vehicle is cold-started, the available charging and discharging power of the power battery is very small, close to 0kw under extreme conditions, making the vehicle unable to drive. Although there is an engine, it is limited by the battery's charging capacity and can only run in a no-load state. The water temperature is difficult to rise, the car is slow to warm up, and the vehicle power is limited.

[0024] The present application provides a solution, which activates the low-temperature anti-breakdown function when necessary by monitoring status parameters, and adjusts the engine power generation power based on the vehicle power control strategy corresponding to the vehicle status parameters, so as to avoid the problem of the vehicle breaking down and being unable to drive due to the limited charging capacity of the battery in an extremely low temperature environment, ensure that the vehicle has sufficient power supply and can operate stably under low temperature conditions, so that the driver has a better driving experience.

[0025] It can be seen from the above embodiments that the present application discloses a vehicle low-temperature anti-anchoring method, device, equipment and storage medium, which relates to the field of vehicle control technology, and discloses a vehicle low-temperature anti-anchoring method, including: obtaining the current state parameters of the vehicle; when the current state parameters meet the parameter requirements, activating the low-temperature anti-anchoring function and obtaining the power generation control strategy according to the current state parameters and the preset parameter threshold; controlling the vehicle driving state based on the power generation control strategy; adjusting the engine power generation of the vehicle according to the vehicle driving state to prevent the vehicle from breaking down. The method activates the low-temperature anti-anchoring function when necessary by monitoring the state parameters, and adjusts the engine power generation based on the vehicle power control strategy corresponding to the vehicle state parameters, so as to avoid the problem of the vehicle breaking down and being unable to drive due to the limited charging capacity of the battery in an extremely low temperature environment, ensure that the vehicle has sufficient power supply and can operate stably under low temperature conditions, so that the driver has a better driving experience.

[0026] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle low temperature anti-anchoring device, etc. The following takes the vehicle low temperature anti-anchoring device as an example to illustrate this embodiment and the following embodiments.

[0027] Based on this, the embodiment of the present application provides a method for preventing a vehicle from being stranded at low temperature. Figure 1 , Figure 1This is a schematic flow chart of the first embodiment of the vehicle low-temperature anchoring prevention method of the present application.

[0028] In this embodiment, the vehicle low temperature anti-breakdown method includes steps S10 to S40: Step S10, obtaining the current state parameters of the vehicle.

[0029] It is understandable that the current state parameters of the vehicle may include the current vehicle allowed charging power, the current ambient temperature and the current vehicle speed.

[0030] It should be noted that in an extremely low temperature environment, the charging power and discharging power of the power battery are very low. Even if the engine is in operation, it cannot charge the battery and is basically in an unloaded state. The load is very small, the water temperature cannot rise, and the air conditioning heating and vehicle power performance are very poor. In order to improve the heating performance and vehicle power performance under such extreme working conditions, the present invention proposes the following technical solution: first, the battery's allowable charging power, ambient temperature, vehicle speed and other signals are obtained, and then the working state of the load on the vehicle and the working state of the motor are controlled according to the above signals to increase the engine's power generation, thereby accelerating the warming of the vehicle, improving the vehicle's power performance at low temperatures, and preventing the vehicle from breaking down.

[0031] Step S20, when the current state parameters meet the parameter requirements, the low temperature anti-anchoring function is activated and the power generation control strategy is obtained according to the current state parameters and the preset parameter thresholds.

[0032] It should be noted that when the current state parameters meet various parameter threshold conditions, it can be considered that the current state parameters meet the parameter requirements.

[0033] It should be emphasized that the current state parameters may include multiple parameters, and the parameter requirements may include multiple requirements. In a specific implementation, if one of the parameters does not meet the parameter threshold, while the other parameters meet the parameter threshold, it may be deemed that the first parameter requirement is met; if two of the parameters do not meet the parameter threshold, while the other parameters meet the parameter threshold, it may be deemed that the second parameter requirement is met.

[0034] It should be further explained that after activating the low-temperature anti-anchoring function, the parameter requirements satisfied by the current state parameters can be determined based on the current state parameters and the preset parameter thresholds, and the control strategy of the power generation can be further determined.

[0035] It should be noted that the power generation control strategy may include a first power generation control strategy and a second power generation control strategy.

[0036] Step S30: controlling the vehicle driving state based on the power generation control strategy.

[0037] It should be noted that the vehicle driving state includes a vehicle load state and a vehicle motor state; at least one of the vehicle load state and the vehicle motor state can be controlled based on different power generation control strategies.

[0038] In a feasible implementation, step S30 may include step A31: Step A31, when the power generation control strategy is the first power generation control strategy, start the vehicle heater, start the vehicle lights, start the seat heating function and start the vehicle thermostat to make the vehicle load state in the vehicle low temperature load state.

[0039] It should be noted that by utilizing load consumption such as the vehicle heater, lights, seats and vehicle thermostat, the engine can operate at a higher power generation capacity and warm up the vehicle faster.

[0040] In this embodiment, by actively increasing the load, the power of the engine under extremely cold conditions is increased, the warm-up speed is accelerated, and the vehicle power is improved.

[0041] In another feasible implementation, step S30 may include steps B31-B32: Step B31, when the power generation control strategy is the second power generation control strategy, start the vehicle heater, start the vehicle lights, start the seat heating function and start the vehicle thermostat to make the vehicle load state in the vehicle low temperature load state.

[0042] It is understandable that starting the vehicle heater, starting the vehicle lights, starting the seat heating function and starting the vehicle thermostat are controls on the vehicle load state.

[0043] Step B32, obtaining a motor torque command, and controlling the motor to be in a stalled state according to the motor torque command.

[0044] It is understandable that obtaining the motor torque command and controlling the motor to be in a stalled state according to the motor torque command is controlling the state of the vehicle motor.

[0045] It should be noted that the motor torque command needs to be within the motor's safe stall torque range and can only be used when the vehicle speed is 0. The motor stall generates heat, consumes part of the electrical power, and further increases the load consumption. In conjunction with loads such as PTC, lights, seats, and the car in a thermostat, the engine can run at a higher power generation power to speed up the warm-up.

[0046] It should be noted that, after obtaining the motor torque command and controlling the motor to be in a stalled state according to the motor torque command, the method further includes: obtaining the motor controller temperature; and controlling the motor to be in a normal state when the motor controller temperature is greater than a preset motor controller temperature threshold.

[0047] In a specific implementation, the temperature information of the motor controller is detected. When the controller temperature is less than the motor controller temperature safety threshold, after the temperature exceeds the threshold, the motor torque command is cancelled and the stall is no longer executed.

[0048] It is understandable that the stalled state refers to a state in which the motor cannot rotate at a fixed position, and at this time the torque of the motor reaches a maximum value.

[0049] In a specific implementation, the temperature information of the motor controller is obtained after the stall. The motor controller is a key component for controlling the operation of the motor, and its temperature directly affects the operating state and life of the motor. In order to ensure the safe operation of the motor controller, a preset motor controller temperature threshold is set. When the temperature of the motor controller is detected, if the temperature is less than the motor controller temperature safety threshold, the motor stall operation continues. If the detected temperature exceeds the preset motor controller temperature threshold, measures are taken immediately to protect the motor controller. Specific measures include canceling the motor torque command, allowing the motor to exit the stall state and return to normal operating state, which can effectively prevent the motor controller from being damaged due to overheating and ensure the stability and safety of the system.

[0050] It is understandable that the load is actively increased to improve the power of the engine under extremely cold conditions, speed up the warm-up speed, and improve the vehicle's dynamics. When the vehicle speed is 0, the motor is safely blocked to increase load consumption, actively increase load consumption, increase the engine load, and speed up the warm-up speed.

[0051] In this embodiment, by continuously monitoring the temperature information of the motor controller, once it is detected that the controller temperature exceeds the set safety threshold, the system will immediately cancel the motor torque command and stop the motor's stall operation. This can effectively avoid equipment damage caused by overheating of the motor controller, extend the service life of the motor controller, and ensure the stable operation of the entire system.

[0052] The above are only two feasible implementations of step S30 provided in this embodiment, and this embodiment does not specifically limit the specific implementation of step S30.

[0053] Step S40, adjusting the engine power generation of the vehicle according to the driving state of the vehicle to prevent the vehicle from breaking down.

[0054] It should be noted that the control of the engine power generation can be achieved based on the control of the vehicle's driving state. Increasing the engine's power generation under extremely low temperature conditions can effectively prevent the vehicle from breaking down.

[0055] In the specific implementation, the specific steps to prevent the vehicle from breaking down at low temperature can be referred to Figure 2In the figure, the vehicle status information is first obtained, and the vehicle status information is judged whether it meets condition one. If condition one is met, the low-temperature anti-anchoring function is activated and the first solution is adopted; if condition one is not met, it is further judged whether condition two is met. If condition two is met, the low-temperature anti-anchoring function is activated and the second solution is adopted; if the second condition is not met, it is closed.

[0056] It can be understood that the first solution and the second solution can be understood as solutions for controlling the vehicle engine state.

[0057] The present embodiment provides a method for preventing a vehicle from being stranded at low temperatures. The method activates the low-temperature stranding prevention function when necessary by monitoring status parameters, and adjusts the engine power generation power based on the vehicle power control strategy corresponding to the vehicle status parameters, so as to avoid the problem of the vehicle being stranded and unable to drive due to the limited charging capacity of the battery in an extremely low temperature environment. The method ensures that the vehicle has sufficient power supply and can operate stably under low temperature conditions, so that the driver has a better driving experience.

[0058] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , step S20, the vehicle low temperature anti-breakdown method further includes steps S21-S22: Step S21, when the current vehicle allowed charging power is less than the preset charging power threshold, the current ambient temperature is less than the preset temperature threshold, and the current vehicle speed is less than the preset vehicle speed threshold, the parameter requirements are met and the low-temperature anti-anchoring function is activated.

[0059] It should be noted that the current state parameters include the current vehicle allowed charging power, the current ambient temperature and the current vehicle speed; the preset parameter thresholds include a preset charging power threshold, a preset temperature threshold and a preset vehicle speed threshold.

[0060] In the specific implementation, a battery charging power threshold △P and an ambient temperature threshold △T are set. ambient , vehicle speed threshold △V, motor safety stall torque threshold △M, motor controller temperature safety threshold △T motor ; When the three conditions of the power battery's allowed charging power <△P, ambient temperature <△T, and vehicle speed <△V are all met, it is considered that the parameter requirements are met and the low-temperature anti-anchoring function is activated.

[0061] Step S22, obtaining a power generation control strategy according to the current state parameters and preset parameter thresholds.

[0062] It is understandable that the power generation control strategy includes a first power generation control strategy and a second power generation control strategy; which strategy to adopt is determined based on current state parameters and preset parameter thresholds.

[0063] In a feasible implementation, step S22 may include steps A221-A222: Step A221, when the current vehicle allowed charging power is less than the preset charging power threshold, the current ambient temperature is less than the preset temperature threshold, and the current vehicle speed is greater than 0 and less than the preset vehicle speed threshold, obtain the first power generation control strategy.

[0064] In the specific implementation, the allowable charging power of the power battery is <△P and the ambient temperature is <△T and the vehicle speed = 0, so plan 1 is adopted: fully open the PTC, turn on the high and low lights, turn on the seat heating, and turn on the vehicle thermostat; give the motor a torque command, and at the same time brake the entire vehicle to put the motor in a stalled state.

[0065] Step A222, when the current vehicle allowed charging power is less than the preset charging power threshold and the current ambient temperature is less than the preset temperature threshold and the current vehicle speed is equal to 0, obtain a second power generation control strategy.

[0066] In the specific implementation, the allowable charging power of the power battery is <△P and the ambient temperature is <△T and 0<vehicle speed<△V. Solution 2 is adopted, with the PTC fully turned on, the high and low lights turned on, the seat heating turned on, and the vehicle thermostat turned on.

[0067] In this embodiment, different power generation control strategies are determined by different vehicle states, and a more targeted power generation control strategy is given according to the vehicle conditions, which can better improve the engine's power generation, thereby speeding up the warm-up, improving the vehicle's power at low temperatures, and preventing the vehicle from breaking down.

[0068] The above are only feasible implementations of step S22 provided in this embodiment, and this embodiment does not specifically limit the specific implementation of step S22.

[0069] It should be noted that when the current state parameters meet the parameter requirements, after activating the low-temperature anti-anchoring function and obtaining the power generation control strategy according to the current state parameters and the preset parameter thresholds, it also includes: when any one or more parameters of the current vehicle's allowed charging power, current ambient temperature and current vehicle speed do not meet the parameter requirements, the low-temperature anti-anchoring function is turned off.

[0070] It is understandable that when any of the three conditions of the charging power allowed by the power battery <△P, the ambient temperature <△T, and the vehicle speed <△V is not met, the function exits.

[0071] The present embodiment provides a method for preventing a vehicle from breaking down at low temperatures. The method dynamically adjusts the power generation control strategy through the current vehicle's allowed charging power, ambient temperature, vehicle speed, and preset parameter thresholds, optimizes energy management, and adjusts the power generation, thereby better improving the engine's power generation, thereby accelerating vehicle warm-up, improving the vehicle's power performance at low temperatures, and preventing the vehicle from breaking down.

[0072] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the vehicle low-temperature anti-anchoring method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
