The hybrid electric vehicle (HEV) gearbox switches between different operating modes to achieve optimal fuel efficiency. However, the vibration caused by mode switching significantly affects the smooth operation of HEVs. Traditional vibration suppression control methods are mostly implemented based on the vehicle controller. Due to delays and long control cycles, the effectiveness of vibration suppression cannot be further improved, thereby limiting the rapid response of the system’s power. To address this issue, this article proposes a vibration suppression strategy for hybrid powertrain mode transitions that actively responds using the motor controller. This strategy aims for speed synchronization, incorporates a model predictive control (MPC) algorithm, and optimizes the design of key control parameters. Research results indicate that the proposed control strategy enhances the effectiveness of vibration suppression during mode transitions and the power output response capability, achieving rapid compensation for system power demands and improving system stability during mode transitions.
