Study of automobile emulated driving model and simulation

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 the automobile engine, and presents simplified structure velocity and direction control models. The simulation structure of simulated driving and logic alestimation of driver operation are discussed, and illegal operation of driver and car backing state are judged correctly. Through the linearization process of the steering framework input function, simulation models for multiple driving cases were derived and effective algorithm was selected to realize the models. Experiment results showed that the presented model and simulation algorithm are correct and feasible.
