ABSTRACT

Based on the Pacejka magic tire formula, this paper establishes a nonlinear full model of a four-wheel independent drive and four-wheel independent steering car. Using the discrete step method, the paper solves the nonlinear implicit differential equations, simplifies the model, and determines its applicable scope. Finally, the paper compares the simulation results of three simplified models with those of the full model. The results show that under the corresponding applicable conditions, the results of the simplified models are very similar to those of the full model, allowing the full model to be replaced by the simplified model.
