Abstract: This paper presents a design method of a torque control strategy for parallel hybrid electric vehicles (PHEV) by using fuzzy logic. Taking the driver command, the state of charge (SOC) of the battery, and the motor/generator speed as inputs, a fuzzy controller and relevant fuzzy rules have been developed to effectively determine the torque distribution between electric motor (EM) and internal combustion engine (ICE). The underlying theme of this strategy is to optimize the operational efficiency of all components, considered as one system. The simulation results reveal that, compared with the conventional logic torque control strategy (LTCS) which uses precise threshold parameters, the proposed fuzzy torque control strategy (FTCS) improves fuel economy and maintains battery SOC within its operation range more effectively.
