In this research, a hybrid electromagnetic actuator is proposed to coordinate the contradictions between dynamic performance and energy consumption of an electromagnetic suspension. The hybrid electromagnetic suspension (HEMS) is configured to operate in the passive energy regeneration mode, active control ride comfort mode or active control driving safety mode depending on the road excitation frequency. Then, the HEMS system is modeled. The simulation results show that the HEMS can automatically switch between different modes, and realize an effective coordination between dynamic performance and energy saving. Finally, a quarter car test is conducted, which verifies the effectiveness of the multi-mode switching control.
