Abstract :
Engine start/stop characteristic of double-clutch hybrid electric vehicle (HEV) was studied. The factors which affect engine start/stop were analyzed, and the disadvantage of the control strategy based on rule for engine start/stop was put forward. In order to optimize the control strategy of engine start/stop, the fuzzy logic control strategy was proposed. Models of double-clutch HEV and control strategy were established based on the co-simulation of AVL CRUISE and MATLAB/SIMULINK. It was drawn through the simulation result that the fuzzy control strategy for the engine start/stop can really prevent from frequent start/stop in low speed, and that the equivalent fuel consumption with fuzzy logic control strategy decreases by 4.6% than that with rule strategy.
