| Abstract: | In order to coordinate the contradiction between the dynamic performance and the economic performance of PEVs， this paper proposed a comprehensive shift schedule based on a two-speed PEV powertrain. Firstly， the strategies of obtaining the torque for low energy consumption were presented under the economic performance mode. Then the dynamic shift schedule and the economy shift schedule for a two-speed powertrain were formulated. The optimization model of comprehensive shift schedule was established with the objectives of the acceleration time during 0~100 km/h and the energy consumption per unit mass. And then the model was solved by the crossover particle swarm optimization algorithm to obtain the shift schedule curves. Three kinds of shift schedule were compared and analysed by using MATLAB/Simulink platform. Results show that the comprehensive shift schedule for low energy consumption may balance the dynamic performance and the economic performance of PEVs. |
