The regenerative vehicle active suspensions have become more and more attractive to many automotive researchers and engineers in recent years. The main benefits of a regenerative vehicle active suspension are the possible improvement of rid e comfort and the regeneration of vibration energy with decreasing the energy co nsumption of active suspension. Above all, the state of the art on regenerative active suspension is reviewed. Then the electromagnetic suspension is summarized as the main type of regenerative suspension. In the end, the key problems in th e development of the electromagnetic suspension are analyzed. With the improvement of electromagnetic technology,the electromagnetic regenerat ive suspension may become one of promising trends of vehicle active suspension.
