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 this paper, the robust yaw stability control based on active steering control is proposed for electric vehicles (EVs). A two degree of freedom control method by a disturbance observer is applied to control design for yaw stabilization. Moreover, the feed-forward disturbance compensator is designed to compensate unexpected yaw moment caused by torque differences between left and right driving motors...
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....
In this paper, a robust yaw stability control design based on active steering control is proposed for electric vehicles. The control system consists of an inner-loop controller (i.e., in this paper, called as a Steering Angle-Disturbance Observer(SA-DOB) which rejects an input steering disturbance and an output yaw disturbance simultaneously by feeding a compensation steering angle) and an outer-loop...
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 be able to precisely detect driver's mistakes and adopt active control in order to increase vehicle...
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...
