Study on range extended electric vehicle engine's multiple operation points control strategy
In order to study the influence of different engine multi-working point control strategies on the fuel economy of the whole vehicle,a range extended electric vehicle was taken as the research object,and engine three-operation-point and five-operation-point control strategies under the premise of satisfying the whole vehicle dynamics were designed.The two control strategies were compared and analyzed under different cycling conditions.The simulation results showed that the three-operation-point control strategy and five-operation-point control strategy could meet the power requirements of the vehicle,and the three-operation-point control strategy had better fuel economy.
