Analysis Vehicle Steering Ability Using Computational Dynamic

Building a car dynamics model is the primary means to evaluate the steering ability of a car. This paper describes a method to analyze the U-turn capability using a car dynamics model built in Python. The model can simulate the car’s trajectory and obtain the corresponding parameters during the car’s motion. The basic parameters of BMW M3 and Chevrolet Cavalier are input into the model, with given initial conditions of U-Turn, the motion state can be obtained through simulation. The slip angle, front tire force, Movement trajectory, and steering speed of the two cars under the same initial conditions are analyzed to compare the U-turn performance of the two models. The results showed that the U-turn performance of the BMW M3 was superior.
