In this embodiment, the control method of the vehicle thermal management system of the present application is applied to the vehicle thermal management system described above, and as shown in fig. 5, the control method of the vehicle thermal management system of the present application may include the steps of:

step S10: detecting a vehicle state of the vehicle;

step S20: and generating a temperature control signal according to the vehicle state, and adjusting the vehicle thermal management system to enter a target temperature adjustment state based on the temperature control signal.

In this embodiment, when the terminal device is running, the terminal device first detects the vehicle to obtain the vehicle state of the vehicle, and then, the terminal device generates a temperature control signal based on the vehicle state and controls the vehicle thermal management system based on the temperature control signal, so that the vehicle thermal management system enters a target temperature adjustment state corresponding to the temperature control signal, and the vehicle thermal management system adjusts the temperature of a target temperature control loop which needs to be temperature-adjusted in the target temperature adjustment state, so as to adjust the real-time temperature values in each target temperature control loop.

Further, in a possible embodiment, the temperature control signal comprises a first temperature control signal and the target temperature adjustment state comprises a first temperature adjustment state; the step S20 may include:

in this embodiment, when detecting that the vehicle state is the adjustment signal receiving state, the terminal device reads a temperature adjustment signal sent by the cockpit, determines a temperature adjustment parameter based on the temperature adjustment signal, and simultaneously, detects an engine in the vehicle based on the temperature adjustment parameter, thereby obtaining an engine state parameter corresponding to the engine, and further generates a first temperature control signal corresponding to the temperature adjustment signal based on the engine state parameter, and then adjusts the vehicle thermal management system based on the first temperature control signal, thereby enabling the vehicle thermal management system to enter a first temperature adjustment state capable of controlling the vehicle heating circuit to generate heat and conveying the heat to the cockpit.

For example, when the terminal device detects that the vehicle is in a whole vehicle power-on state and the cockpit sends out a warm air request signal, the terminal device determines that the vehicle state is in an adjustment signal receiving state, at this time, the terminal device reads a first temperature set value contained in the warm air request signal and detects an engine of the vehicle so as to detect whether the engine is started and acquire an engine water temperature of the engine, and when the terminal device further determines that the engine is not started, compares the engine water temperature with the first temperature set value so as to determine whether the engine water temperature is smaller than the first temperature set value, if the terminal device determines that the engine water temperature is smaller than the first temperature set value, generates a corresponding first PWM control signal based on the first temperature set value, then the terminal device adjusts a vehicle thermal management system based on the first PWM control signal, in order to make the vehicle thermal management system enter a first temperature regulation state for regulating the vehicle heating loop 35, finally, in the first temperature regulation state, the vehicle thermal management system regulates the vehicle heating loop 35 based on the first PWM control signal to make the warm air water return valve in the vehicle heating loop 35 only 8 ac on and ab off, calculates the heating power corresponding to the PTC10 based on the first temperature set value, the first actual temperature value, the blower wind speed value and the blowing mode corresponding to the first PWM control signal, further controls the PTC10 to heat according to the heating power, simultaneously, the terminal equipment calculates the first operation power of the warm air loop water pump 11 based on the first temperature set value corresponding to the first PWM control signal, thereby controlling the warm air loop water pump 11 to operate according to the first operation power, so that the PTC-heated coolant circulates in the vehicle heating circuit 35 to enter the warm air core 22 in the vehicle heating circuit 35, and at the same time, the terminal device controls the blower 20 to operate so as to blow the heat in the warm air core 22 into the cabin 42 through the blower 20.

In addition, in this embodiment and another embodiment, if the terminal device detects that the engine is in a start state and the engine water temperature is greater than or equal to the first temperature set value, a corresponding first temperature control signal is generated based on the first temperature set value, and the vehicle thermal management system is adjusted based on the first temperature control signal, so that the vehicle thermal management system enters a first temperature adjustment state for adjusting the vehicle heating circuit 35 and the engine temperature control circuit 37, finally, in the first temperature adjustment state, the vehicle thermal management system adjusts the vehicle heating circuit 35, so that the warm air return valve in the vehicle heating circuit 35 is only 8 ab on, ac is closed, and the PTC10 is controlled to keep the closed state, and further, based on the first temperature set value and the first actual temperature value, the first operation power of the warm air circuit water pump 11 is calculated, so that the warm air circuit water pump 11 is controlled to operate according to the first operation power, so that the cooling liquid with heat generated in the engine 33 enters the air core 22 through the warm air circuit water pump 11, passes through the warm air return valve 35 and the fan heater core 20, and the blower fan 20 is controlled by the fan heater core 20 through the warm air return valve 35, and the blower fan 20 is controlled by the fan device 42, and the warm air circulation device is controlled in the vehicle heating circuit 20.

In addition, in the present embodiment and another embodiment, when the terminal device detects that the vehicle is in the parking charge state, the terminal device detects the DCDC24 in the motor temperature control loop 38, so as to obtain the DCDC temperature, and at the same time, the terminal device obtains a preset second set temperature, compares the DCDC temperature with the second set temperature, and generates a second PWM control signal based on the comparison result, and then adjusts the vehicle thermal management system based on the second PWM control signal, so as to make the vehicle thermal management system enter a second temperature adjustment state in which the motor temperature control loop 38 is adjusted, and finally, when the DCDC temperature is less than the second set temperature, the thermal management system controls the electric drive loop water pump 5 and the low-temperature radiator fan 2 in the motor temperature control loop 38 to stop, and when the DCDC temperature is greater than or equal to the second set temperature, the thermal management system adjusts the rotational speeds of the electric drive loop water pump 5 and the low-temperature radiator fan 2 in the motor temperature control loop 38 based on the second PWM control signal, so as to adjust the cooling rate of the motor 26.

In this way, the terminal device is able to regulate the motor temperature control loop 38 by the vehicle thermal management system when the vehicle is in a powered-up state or a parked state of charge, thereby performing a cooling operation on the motor 26 through the motor temperature control loop 38.
