The invention discloses a cabin climate automatic control system of a pure electric vehicle and a control method thereof. The control system comprises a controller, an environment temperature sensor,an in-vehicle temperature sensor, an evaporator temperature sensor, a heater temperature sensor, a sunlight sensor, a compressor, a heater, an air blower, a mode air door driver and a mixed air door driver. According to the invention, the climate comfort of an automobile cabin can be ensured, and high efficiency and energy conservation can be realized; the target temperature of the evaporator andthe target temperature of the heater are calculated, and the rotating speed of the compressor and the power of the heater are output by adopting a PID algorithm, so that the purpose of accurately controlling the target air outlet temperature is achieved, and energy waste caused by air mixing by adopting a mixed air door is avoided.
Description
technical field [0001] The invention relates to the technical field of pure electric vehicle cabin climate control, in particular to a pure electric vehicle cabin climate automatic control system and a control method thereof. Background technique [0002] With the promotion of the new energy vehicle industry policy and the development of new energy vehicle technology, the proportion of new energy vehicles in the market is getting higher and higher. Pure electric vehicles powered by batteries do not have engines to power air-conditioning compressors, and refrigeration systems are common. Electric compressors driven by motors are used; in addition, since pure electric vehicles do not have engines, engine coolant cannot be used to provide heat for air-conditioning and heating. The heating methods generally use air-heated PTC heating and water-heated PTC heating. At present, the mileage of pure electric vehicles has been receiving much attention. As an important part of improvin...
