The existence of self-aligning torque makes the wheel direction of the car consistent with the driving direction, which is the key to ensure the stable straight-line driving of the car. In this paper, we will mainly apply Python to establish the force and motion models of BMWM3 and Chevrolet under different driving modes, and work through the function of the self-aligning torque through the classical calculation model of the self-aligning torque. In our calculation, we examine the variation of self-aligning torque of BMW and Chevrolet with the change of time under various driving conditions. Then, we evaluated the dynamic mechanical properties of the vehicle during driving, and provide reference for the design of vehicle parameters. We also proved their relationship between self-aligning torque and slip angle for the two cars and found the maximum torque values according to the slip angle. Use such model, it becomes possible to calculate the real-time self-aligning torque only with the data measured by python programming.
