  • Control strategy for engine start-stop in hybrid electric vehicle

    • 摘要：

      A simulation model was built for the self-developed parallel hybrid electric vehicle (HEV) with dual clutch configuration using the software of powertrain system analysis toolkit (PSAT) with the forward-looking simulation approach. The model was used to perform the optimization simulation of the control strategy for the engine start-stop in HEV. The results showed that the optimal fuel economy can be realized when the engine start power is 10 kW/1200 r·min-1 and the engine stop power is 4 kW/800 r·min-1. Under these power settings, the engine and the integrated starter-generator (ISG) motor can collaborate well with each other, the operating mode switching of the powertrain is smooth. The vehicle tests validated the practicality of the developed control strategy.
