First, the energy consumption of a passive suspension via damper and the energy demand for an LQG optimal vehicle active suspension are investigated, showing valuable potentials for an active suspension with vibration energy regeneration. Then, the feasibility of energy regenerative approaches is discussed, and an electrical active suspension configuration is proposed with the description of its working principle and structure. The study on feasibility and configuration shows that the proposed configuration and control approach can be an effective approach for the active control and the energy regeneration of vehicle vibration. And potentially, it also can be useful for future electrical suspension design of electrical vehicles.
