Dynamic Simulation System For Automobile Driving Simulator

Driving fatigue is an important cause of traffic accidents, for the study of driving fatigue of the human engineering, we design a dynamic steering simulator according to the factors of causing driving fatigue. It's convenient for fixing the test equipment and gathering the test data, and also has the excellence of no pollution, safety, saving energy, and no influence of environment and climate. It also has the value of study and practicality.The dynamic steering simulator discussed in this paper has a power simulator, and has good dynamic effect because its four tyres are rolling when running. The power simulator simulates the car inertia impulsion and is avail of shifting when running. The effect is closer to the real driving condition than other former driving simulators. We use industrial computer to control the servo system of electro-hydraulic to realize the action of the simulator and the simulation of the roads ride.This paper mainly introduces the study of the dynamic system of the steering simulator, including the design of the mechanism structure, the design and control of the servo system of electro-hydraulic, at the same time, it also introduces the control method of PID. It also gets the open loop transfer function according the technical parameter asked. The paper not only introduces the design methods of dynamic simulation and the theory study of the roads ride, but also uses MATLAB to simulate. By the method of simulation, it's easy to get the initial driving signals of the servo system of electro-hydraulic.It's proved that the effect is as good as expected by the means of fixing hardware and debugging the control software. The practice testifies the method we studied is practicable, and the method has some innovation. It provides a scientific test platform for the study of driving fatigue.
