Investigation of Driver-Controller Interaction in Vehicle Rollover Prevention

Vehicle rollover Is a serious problem in traffic safety. A supervisory control paradigm of rollover prevention controller design is employed. The differential braking controllers are design based on two rollover threshold reported in the literature, namely the load transfer ratio and roll energy methods. The necessary controller adjustment with respect to loading condition is also investigated. The interactions of the controller with the human driver are to be investigated. Two platforms, a PC based driving simulator and a scaled vehicle testing system, are used to investigate the designed controllers. Preliminary results confirm the validity of the two platforms, and the advantage of the controller adjustment. Evaluations of the rollover prevention controllers and the human driver interactions will be performed in future work.
