specifically, the fourth state setting circuit can adjust the target power of the air conditioning system to the first setting power, the first setting power can be 50% of the required power, so that the cabin temperature needs to be adjusted to 25 ℃, when the current cabin temperature is higher than the setting temperature signal, the target power of the air conditioning system for refrigeration can be adjusted to 50% of the corresponding power of 25 ℃, and when the current cabin temperature is lower than the setting temperature signal, the target power of the air conditioning system for heating can be adjusted to 50% of the corresponding power of 25 ℃, so that a comfortable driving environment can be provided, the energy of a power battery cannot be wasted excessively, and the cruising ability can be improved.

In step S412, the power of the air conditioning system is not limited.

Step S413, the cabin temperature is higher than the set temperature signal; if yes, go to step S414, otherwise go to step S415; step S414, the fifth state setting circuit adjusts the power utilization state of the air conditioning system and adjusts the target refrigerating power of the air conditioning system to a second set power; in step S415, the fifth state setting circuit adjusts the power consumption state of the air conditioning system and adjusts the target power for heating the air conditioning system to the second set power.

Specifically, the set temperature signal may be 25 ℃, the difference circuit makes a difference between the set temperature signal and the cabin temperature signal, and sends the difference signal to the fourth comparison circuit, the first set difference signal may be 3 ℃, if the absolute value of the difference between the cabin temperature and the set temperature signal is greater than the first set difference signal, it indicates that the temperature of the cabin at this time cannot enable the driver to drive comfortably, the fourth comparison circuit may generate a fourth comparison signal of a second level, the control circuit may control the air conditioning system to be turned on, when the current cabin temperature is higher than the set temperature signal, the target power of the air conditioning system refrigeration is set to be a second required power, and the second set power may be 30% of the required power; when the current cabin temperature is lower than the set temperature signal, the target power of the air conditioning system for heating is set to be a second required power, and the second set power can be 30% of the required power; therefore, the temperature of the cabin needs to be adjusted to 25 ℃, the target power of the air conditioning system can be adjusted to 30% of the corresponding power of 25 ℃, a comfortable driving environment can be provided, the energy of a power battery cannot be wasted too much, and the cruising ability is improved.
