This paper deals with the modelling and robust control system synthesis of intelligent vehicles for general lateral motion in intelligent transportation system applications. The lateral vehicle dynamics for general lane following are firstly derived in a unified framework. Based on a coprime factor plant description, the two-degree-of-freedom based H infinite loop-shaping control scheme is presented for lane keeping and changing manoeuvres simultaneously. The resulting robust controller is generally of high order and has to be reduced for real implementation. Also, the reduced-order controller is evaluated in both the frequency- and the time-domain analysis. Finally, it is found that the proposed automatic steering controller provides robust performance and stability for a given vehicle manoeuvering in the presence of parameter variations of vehicles.
