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...
In recent years, the demand for safer vehicles has increased. According to traffic accident reports prepared by the Metropolitan Police Department in Japan, almost all traffic accidents are caused by human errors such as driver negligence or operational mistakes. Therefore, future technologies need to precisely detect driver's mistakes and adopt active control in order to increase vehicle safety....

Active front steering (AFS) is an effective technique to stabilize motion control such as direct yaw control (DYC) for vehicle. However, if AFS intervenes excessively during the steering process, it becomes difficult to resolve the interference between driver steering and automatic steering by AFS. As a result, vehicles are at present rarely equipped with AFS. We propose a reactive torque control...
