Lateral Stability Control of Car-Trailer Combination Based on 4WS
Rollover and jack-knifing of car-trailer combination on overtaking or obstacle avoidance under emergency are serious threats for motorists. A car-trailer combination model was built in this paper. The kinematics of car-trailer combination has been analyzed, and a 4 DOF model was built to act as the controller predictive model. The dynamics simulation for yaw rate following and anti-rollover has been performed on the dynamic car-trailer combination model. The results show that the lateral stability control based on four-wheel steering proposed in this paper can stabilize the car-trailer combination, rollover and jack-knifing are prevented from and the car-trailer combination more can follows accurately the driver's desired path.
