Abstract

With the popularization of vehicles in the world, the problem of driving safety has also received more and more attention. Among them, understeer and oversteer are the main causes of many traffic accidents. In order to explore the causes of understeer and oversteer and propose solutions, this paper builds models of two real cars, BMW M3 and Chevrolet Cavalier, in python, and simulates two turns of lane change and U-turn, as well as the side of the vehicle under different parameters. The simulation of the variation of the slip angle leads to the conclusion that the variation of the slip angle is the main cause of understeer and oversteer. Subsequently, this paper investigates and discusses other causes of understeer and oversteer, and finds that vehicle weight and driving speed are also the causes of understeer and oversteer. The solution is discussed, and specific solutions are given, which is intended to ensure the safety of drivers who encounter similar emergencies.
