A method of vehicle dynamics prediction to anticipate the risk of future accidents: Experimental validation

Abstract

This article presents a prediction algorithm for vehicle dynamics parameters, to expect possible risk situations in future instants. The methodology consists in adopting assumptions about the trajectory, velocity, and acceleration in future instants and use these assumptions, allied to previous road information to calculate the future tire/road lateral and vertical efforts and side slip angle using a state observer. Once calculated, the risk indicators: the lateral load transfer (LTR) and the lateral skid indicator (LSI), based on these efforts could be predicted in order to expect and avoid possible dangerous situations. Experimental validations are shown using our laboratory vehicle in a real situations.
