摘要：
When the four-wheel-drive electric vehicle steers at high speed, the nonlinear characteristics of tyre will make the vehicle to appear some instable problems such as overswing, sideslip, oversteering and understeering.In order to tackle these instable problems, a steering stable hierarchical control strategy for four-wheel-drive electric vehicles is proposed. The outer-layer map-based sliding mode control scheme is to produce additional yaw moments to stabilize the vehicle; the inner-layer torque model predictive control scheme is to implement the torque distribution of four tires. Simulation results show that the proposed control strategy can effectively ensure the stable steering of the vehicle. © 2021, Editorial Department of Control Theory & Applications South China University of Technology.
