Yaw Moment

Aiming at the lateral stability control problem of distributed driven electric vehicles under high speed steering condition, a hierarchical control algorithm of direct yaw moment is designed. The upper control takes the 2-DOF vehicle model as the reference model and uses the sliding mode control to obtain the required yaw moment by tracking the desired yaw velocity and the desired vehicle side-slip angle. The lower control optimizes the distribution of four wheel torque with the minimum tire utilization rate. Finally, Carsim/Simulink was used for model building and co-simulation, and the control effect of PID algorithm was compared. The results show the hierarchical control algorithm achieves the expected goal of improving vehicle lateral stability.

In this paper, the problem of vehicle yaw control using differential braking is investigated. The proposed control structure employs the wheel slip controller to apply differential braking to generate the yaw moment calculated by the yaw controller. A fuzzy logic based target slip allocation method is also designed. Due to system uncertainties and wide range operation conditions, two different yaw controller which are based on sliding-mode control and PID control are designed, and their performances are compared by hardware in loop simulation. The obtained results show the effectiveness of the proposed control structure with both yaw controllers, but the sliding mode based yaw controller can be more robust.
