Abstract :
The precise calculation of front wheel toe-in of vehicles is the base of the control for toe-in tracing camber and simulation of vehicles´ handling and stability. Since the match between the toe-in and camber depends on several factors, it is difficult to give a precise calculation of the toe-in according to a given camber. A semi-empirical approach is developed based on theoretical analysis combined with measurement techniques. As an application, the developed approach is used to determine the optimistic front wheel toe-in of a domestic 1026 model pick-up vehicle. Based on the sideslip test of the vehicle, the formulation of the sideslip value and toe-in is determined by regress analysis. By comparing the theoretical and the regressed toe-in corresponding to the minimum sideslip value, the theoretical formulation is modified to suit for the pick-up vehicle considered. The proposed methodology provides a precise mathematical model for the control of toe-in tracing camber, which might be used to improve the high speed safety of vehicles.
