Research on Energy-fed Suspension Control System of New Energy Vehicles Based on Energy Flow Analysis

Suspension is the general name of device that connects conductive force between car body and wheels. Among them, operational stability ride comfort are two contradictory requirements in actual driving. In traditional vehicle suspension system, order to maintain vehicle, vibration energy caused by uneven road surface usually dissipated passive shock absorber form heat. If this part can be recovered an effective way, demand whole system reduced. Usually, stiffness semi-active constant, damping coefficient will change automatically with driving conditions. Its advantages simple structure, no need consume automobile power, conditions, which effectively improve riding handling stability. This paper expounds problems encountered suspension, analyzes semi-automatic control strategy regenerative new vehicles from perspective flow.
