Active Front Steering enhances vehicle performance by making optimal road wheel angle based on vehicle state information. This information includes steering wheel angle, vehicle speed, lateral acceleration and yaw rate. To generate optimized road wheel angle under various vehicle maneuver, several mechanisms are studied and developed by steering suppliers in the world and these mechanisms are commercialized by car makers. Linkage mechanism, harmonic gear, planetary gears are widely referred mechanism. Among them planetary mechanism is most commonly known actuator. In this paper planetary gear system is analyzed using dynamic simulation model and requirement in choosing appropriate electric motor is described.
