Uncertain analysis of vehicle handling using interval method

Abstract

To solve the dynamic response problem that contains uncertain parameters, the uncertain differential equations need to be calculated. In this study, a new efficient numerical interval method for uncertain differential equations is presented. The interval dynamic analysis of a Two-Degree-of-Freedom (2DOF) bicycle car model with uncertain parameters is presented. Considering the vehicle parameters as the interval variables, the lower and upper bound of the vehicle handling uncertain responses are obtained by the proposed numerical interval method. The comparison between the numerical interval method and the Monte Carlo method indicates that the proposed numerical interval method is more effective.
