Abstract

Driver behaviour is a major cause of traffic accidents. In response to this problem, this paper proposes a solution to increase the driver's reaction time by changing the vehicle's stability through the toe-in angle The toe angle of a vehicle is an important parameter in vehicle design, which has a great influence on the stability and steering ability of the vehicle. In this paper, the influence of the toe angle on the vehicle stability is determined by analyzing the influence of the vehicle toe angle on the lateral force generated when the vehicle wheels are deflected. This paper simulates the force of different toe angles when the wheels suddenly turn by the carmaker and establishes the relationship between the stability of the vehicle and the toe angle when the wheels are deflected by analysing the lateral force on the vehicle under different toe angles. A mathematical model to analyse the effect of toe angle on vehicle stability. The results of the modeling simulations show that the increase of the toe angle can effectively reduce the lateral force on the vehicle when the wheels are deflected. From this result, it is concluded that increasing the toe angle can effectively increase the stability of the vehicle.
