A fuzzy-logic-based energy management and power control strategy for PHV (Parallel Hybrid Vehicles) are presented. The main objective is to optimize the fuel economy of the PHV, by optimizing the operational efficiency of all its components. The controller optimizes the power output of the e1ectric motor generator and the internal combustion engine by using vehicle speed, driver commands from accelerator and braking pedals, SOC (State Of Charge) of the battery and the electric motor/generator speed. Separate controllers optimize braking and gear shifting. Simulation results show potential fuel economy improvement relative to other strategies that only maximize the efficiency of the combustion engine.
