Abstract

Abstract: In order to improve the handling stability of three-axil vehicle at high speed, a control method, that integrates all-wheel steering system and direct yaw moment control system, is proposed, which includes the upper coordinated controller and the lower controller. Based on the 18-DOF vehicle model, the load distribution model and the Dugoff nonlinear tire model, the steering on low friction road and the obstacle avoidance steering are simulated. The simulated results show that the integrated control method can improve the handling stability and active safety of vehicle at high speed.

Key words: ordnance science and technology, three-wheel vehicle, all-wheel steering, yaw moment, horizontal integration control
