Based on the model of driver-vehicle with 4WS closed-loop system considering tire nonlinearity, the nonlinear motion stability of vehicle with steering angle input was analyzed in this paper. From the point of view of system and control theory, some inherent relations of nonlinear motion stability were revealed quantitatively for vehicle with 4WS on different roads. The nonlinear motion stability...
Traditional active safety systems in automotive industry use the vehicle current state and additional optional measurements to plan their intervention. In general, the computation of the most convenient action to undertake in order to guarantee a safe driving is performed without any reference to what the optimal maneuver, predicted on the basis of the vehicle current state and future road geometry/conditions,...
Vehicle rollover accounts for a significant percentage of fatal accidents in the USA and worldwide. In this paper, two rollover indexes are proposed and analyzed. The first rollover index estimates the actual lateral transfer ratio (LTR) while the second, referred to as dasiapredictive lateral transfer ratiopsila (PLTR), incorporates the predictive influence of the driver's steering input, thus allowing...
