Integrated Chassis Control System for Improving Vehicle Stability

The control authorities of active front steer, active rear wheel steer, brake-based stability control system and 4 WD-based stability control system are compared and analyzed. The results show that these systems are reciprocal for each other and the vehicle stability and handling can be improved through coordinated control. Based on the analysis result, a coordinated principle is advised. The simulation results show that the coordinate chassis control can properly distribute the yaw moment to DYC and AFS control system and improve stability together.
