Abstract A hybrid electromagnetic suspension with three modes was proposed here. Three modes focused on ride comfort, tire grounding ability and comprehensive performance of a suspension, respectively. The contradiction between ride comfort and tire grounding ability was coordinated. The dynamic model of the hybrid electromagnetic suspension was established. Weight coefficients of LQG control strategy under the three modes were determined. The effects of the suspension’s stiffness and damping on its dynamic performance and energy consumption characteristic were analyzed under different modes, the suspension’s stiffness and damping values under different modes were determined. Simulation analysis was performed. The results showed that compared with a traditional passive suspension, the hybrid electromagnetic suspension can improve a suspension’s dynamic performance effectively; it can significantly reduce a suspension’s energy consumption compared with an active suspension. Finally, the tests were conducted. It was shown that the test results agree well with those of simulation, the correctness of the simulation results is verified.
