Abstract：To coordinate the contradiction between improving the dynamic performance and reducing the energy consumption of the system, the hybrid electromagnetic active suspension (HEMAS) was used as a potential solution. Based on the improved skyhook control strategy, the general energysaving mechanism of HEMAS was realized compared with linear electromagnetic active suspension (LEMAS). Taking the passive suspension and the LEMAS as comparison objects, a comparison bench test was carried out. The test results show that compared with passive suspension, the RMS of vehicle acceleration and suspension dynamic deflection of the HEMAS are respectively reduced by 23.35% and 14.97% with good tire grounding ability. Compared with LEMAS, the electric power consumption of the HEMAS is reduced by 70.60% for the same dynamic performance, which verifies the superiority of HEMAS with consideration of the system dynamic performance and energy consumption.
