Abstract

For hybrid electric vehicles (HEVs), the hybrid power system will switch between different working modes to cope with different driving conditions. This paper formulates three engine-start control strategies for a single-motor multi-mode parallel hybrid power system to reduce the jerk and switching time during specific mode switching process. The dynamic model of engine-start process during mode switching is established and three engine-start control strategies are proposed based on the characteristics of the system configuration. Through simulation, the optimal engine starting control strategy is selected. The vehicle speed tracking effect is better and the vehicle speed recovery time after mode switching is reduced.
