Hybrid vehicle air conditioner heating control method based on double-waterway circulation framework

The invention discloses a hybrid vehicle air conditioner heating control method based on a double-waterway circulation framework, and the main design concept of the hybrid vehicle air conditioner heating control method lies in that through optimization of an engine and a WPTC control strategy, according to a demand instruction sent by a passenger compartment, high voltage is used for controlling the WPTC to heat a whole vehicle or waste heat of the engine is used for heating compensation, and in addition, the engine and the WPTC control strategy are optimized. The battery heating performance and influence are comprehensively considered, superposition control logic is adopted, and the heat of the battery and a passenger compartment can be accurately controlled. Specifically, a WPTC is introduced into the air conditioning system and is connected in series in a water path, and the output power of the WPTC can be comprehensively controlled according to the two factors of a battery and a passenger compartment.
