In active automobile driving training simulator, the steering framework in the simulated cabin has multi-input, multi-coupling and non-linear control effect. A driving training simulator requires dynamic model suitable for fast real-time simulation. This paper uses polynomials to express the load characteristics of an automobile engine, and presents simplified structure velocity and direction control models. The simulation structure of simulated driving and the logic estimation of driver operation are discussed, and illegal operation of driver and car backing state are correctly judged. Through the linearization process of the steering framework input function, simulation models for multiple driving cases are derive and effective algorithm is selected to realize the models. Experimental results show that the presented model and simulation algorithm are correct and feasible.
