Fuzzy Logic Torque Control Strategy for Parallel Hybrid Electric Vehicles

摘要：

In this paper, a design method of a fuzzy torque control strategy (FTCS) is presented for parallel hybrid electric vehicles (PHEVs). Considering all components as one system, the controller receives vehicle information such as the driver command, the state of charge (SOC) of the battery, and the motor/generator speed as input to determine the torque distribution between electric motor (EM) and internal combustion engine (ICE). The simulation results reveal a potential efficiency improvement in all components especially the fuel economy by comparing with the conventional logic torque control strategy (LTCS) which uses precise threshold parameters.
