A new longitudinal speed control strategy is proposed.It used the lateral jerk information as the feedback to predict the longitudinal acceleration and deceleration,which is especially beneficial to a sharp curve turning at a high driving speed.The performance of the controller is validated with Matlab/Simulink.The simulation results indicate that compared with the traditional vehicle,the G-vector controller can reduce the turning radius and improve the vehicle stability and agility obviously.And the proposed longitudinal speed control strategy could trade-off the longitudinal and lateral acceleration by using the tire force during the turning.
