Research on Control Method of Hybrid Electric Vehicle Considering Air Conditioning Power

Based on the key components and controller models of the hybrid electric vehicle, the energy flow of each component of the vehicle under different power of the A/C (Air-Conditioning) system is analyzed and calculated. The control method adjusts the torque distribution strategy between the engine and motor. In this paper, the energy flow of each component is analyzed under the condition of different power of the air conditioning accessories in the standard cycle condition. Compared with the traditional control method, the improved vehicle control method can be used in different accessory powers to reduce the overall energy consumption of the vehicle. When the power of air conditioning accessories are 3kW and 5kW, the energy consumption of the new method can improve by 3.8% and 8.6%. The results show that the proposed control method can reduce the comprehensive energy consumption of the hybrid electric vehicle under the different air conditioning powers.
