Dynamic car driving simulator is able to correctly simulate car driving action and get the same feeling of real car driving simulation equipment in the main performance . Car driving simulator combined with the real vehicle driving training , driving training can improve efficiency , shorten the training cycle . Therefore , the development of automobile driving simulator has a very important practical significance . In this paper, the dynamic car driving simulator information collection , processing and visual system . First, the details of the collection object is a car driving simulator operating system , the acquisition component selection and acquisition circuit design , the completion of the three pedals , gear shift control mechanism , steering control mechanism to manipulate the amount of information collected . Secondly, the power supply module is designed based on the microcontroller Atmega128 , the information processing circuit module , the control circuit module and a communication module . Accordance with the RS422 serial data interface standard set of communication protocols , system program using C language , the manipulation of communication between the system and the host computer , the control of automotive instrument cluster , lights and other devices . In the visual system , the vehicle dynamics , through the analysis of the relationship between the engine power, vehicle acceleration , vehicle speed , three full consideration affecting the movement state of the car a few amount of manipulation input , such as gear, throttle , clutch , brake and steering wheel action status , including the establishment of the dynamic equations and manipulate the stability equation approximately 4 degrees of freedom of vehicle dynamics model , at the same time , the use of the French OKTAL developed SCANeR Ⅱ software to establish a three-dimensional driving scene and write some special driving the situational control procedures .
