The focus of this paper is the control strategy used to control general parallel hybrid electric vehicles (HEV). The torque split control problem of HEV is formulated as the optimal control of a switched system. A model-based strategy for fuel-optimal control is presented. The optimal control problem of such a switched system is formulated as a two-stage(More)
In order to improve the control system precision, a novel fuzzy control method is being proposed in this paper. The fuzzy logic controller (FLC) based on the double-fuzzifications methods is implemented. The FLC is different from the conventional design method. No complex algorithm is required to implement the controller. The actual performance of the novel(More)
