Study On Information Acquisition, Processing And Visual System Of Dynamic-type Vehicle Driving Simulator

Dynamic-type vehicle driving simulator is a simulated car, which can drive the right moves and get the same feeling on the main performance. Training which combines the vehicle driving simulator driving and a car driving can improve efficiency and shorten the training cycle. Therefore, the development of the training vehicle driving simulator is of great significance.In this dissertation, study on the information Acquisition, processing and visual system of dynamic-type vehicle driving simulator is proposed.Firstly, the acquiring target - vehicle driving simulator manipulators, the choice of acquisition components and the design of acquisition circuit are presented in detail in information acquisition system, which completes the acquisition of signals on three pedals, gear and steering wheel.Secondly, based on a single chip processor, Atmegal28, the power circuit, information processing circuit, control and communication circuit are developed. After setting the RS422 protocol and programming system procedure by C-language, the communication between the manipulation system and the master computer is completed, and the control of instrument, lights and other devices is realized.Finally, in visual system study, using of vehicle dynamics knowledge, analyzing the relationship among engine power, vehicle acceleration and speed, fully considering the effect of several manipulation inputs (including shift, throttle, clutch, brake and steering wheel) to motor action status, established an approximate 4-degrees freedom vehicle dynamic model which involves sport equations and manipulating stability equations. Applying the software SCANeRâ…¡which is developed by a French company OKTAL, a virtual driving scene is established and some special driving scenarios control procedures are programmed.
