Abstract
This paper proposes robust lateral motion control of vehicle with steer-by-wire system. For the vehicle with steer-by-wire system, we design the observer to construct a lateral motion control system without a yaw rate sensor and a lateral speed sensor. The lateral motion control system considering a disturbance caused by a crosswind is constructed. In addition controllability of the proposed system is also considered. A condition for the controllability is derived from the controllability matrix. Computer simulation results are shown to confirm the effectiveness of the proposed control system.
