Electric automobile air conditioner control method based on thermal comfort and low virus infection risk

Abstract

The invention relates to an electric vehicle air conditioner control method based on thermal comfort and low virus infection risk, and belongs to the technical field of vehicle thermal management. Themethod comprises the following steps: S1, establishing a thermal coupling model of an automobile air conditioning system and a passenger compartment; s2, establishing a virus infection risk evaluation model based on the passenger compartment; s3, establishing a model prediction controller matched with the thermal coupling model of the automobile air conditioning system and the passenger compartment; and S4, in combination with the virus risk infection evaluation model, establishing a complete air conditioning system controller for comfort and health of drivers and passengers in the passengercompartment. Model prediction control is adopted, the method is suitable for a multiple-input-multiple-output air conditioner control system, the controller is efficient and energy-saving, the effectof reducing the virus infection risk is achieved, and comfort and safety of passengers are guaranteed in the whole vehicle running process.

Description

technical field [0001] The invention belongs to the technical field of vehicle thermal management, and relates to an electric vehicle air-conditioning control method based on thermal comfort and low virus infection risk. Background technique [0002] Considering the comfort, safety and health requirements of the driver and passengers in the passenger compartment, the heating, ventilation and air conditioning system (HVAC) is one of the most important auxiliary systems of the vehicle. However, the HVAC system consumes a lot of energy, and electric vehicles are faced with the energy consumption problems brought about by the HVAC system, resulting in a decrease in the cruising range of electric vehicles. Relevant studies have shown that HVAC systems can reduce the cruising range of electric vehicles by 30%-40%, and even more in some extreme conditions. In terms of intelligence, due to the development of intelligent automobiles, automotive air conditioners need to be more intel...
