Study on cornering stability control based on pneumatic trail estimation by using dual pitman arm type steer-by-wire on electric vehicle

This paper proposes novel high accuracy road condition estimation called Tire Grip Margin (TGM), and TGM is estimated by using dual pitman arm type steer-by-wire and lateral force sensor and estimator. In addition, we propose cornering stability control technique based on the TGM. It can help driver and vehicle before unstable state. We verify our proposed system achieves robust vehicle dynamics control on the low friction road by CarSim. CarSim is simulator for the vehicle dynamics.
