Abstract: Hybrid electric vehicle(HEV) is a very complicated non-linear system, whose performance is affected by lots of control parameters. To optimize this system, the routine optimization approach is inefficient, and the reliability of optima depends on the precision of model. An HEV bus dynamic simulation model is built for performance analysis by the interlinking of advanced software AVL CRUISE and MATLAB/Simulink. For achieving minimum fuel consumption and emissions, a multi-objective genetic algorithm(GA) optimization method is applied to getting the optima of work modes and energy distribution in different city bus cycles, which finds the compatible control logic parameters and saves much time. The feasible solution can improve the fuel economy and emissions simultaneously and provide wider choices for different requirements in HEV design.
