In this paper the idea of energy regeneration of active suspension system in hybrid electric vehicle is presented and its influence on the fuel consumption and emissions of vehicle is investigated through computer simulations. Active suspension systems employ active actuators to apply force and control the vibrations of vehicle body. The active actuators either insert energy to the system or extract the energy of vibrations when required. Using an energy regeneration system, the extracted energy of vibrations can be recovered and stored in the energy storage system. In hybrid electric vehicles, the active suspension supplies its required energy from the electric energy storage system of vehicle. In this work, a hybrid battery/supercapasitor energy storage system is employed to supply the required energy of active suspension and other electric components of vehicle. The simulation results show that with application of the energy regeneration system, the fuel consumption and exhaust emissions of vehicle is reduced.
