电动汽车增程器燃油效率优化控制
Optimal control of electric vehicle range extender for fuel efficiency
摘要
Abstract
In order to improve the fuel efficiency of electric vehicle range extender, and reduce the vehicle fuel con-sumption, a range extender fuel efficiency optimal control approach which is based on PRP conjugate gradient method is proposed in this paper. First, the discrete-time range extender fuel efficiency optimization model is developed, in which the fuel efficiency for a given energy command is chosen as the cost function, and the torque of the engine and generator are utilized as the optimized variables. Then, the methods of processing the maximum speed and torque of engine and generator are analyzed, and the step-by-step details to implement the proposed PRP conjugate gradient method based fuel efficiency optimal control approach are described. Finally, simulation and experiments are carried out and the results show that the optimal solutions obtained by the proposed approach improve the fuel efficiency of the range extender effectively.关键词
