Study And Implemntation Of Automobile Simulator Driving System Based On MCU And DirectX Technology

Automobile driving simulation system is a simulator which oriented to the drive training and recreation.It use computer technology,control technique, sound-image technology and vehicle engineering technology to simulate the drive environment of vehicle,let the trainees study the realistic vehicle steer indoors, it can replace the parts of the driver training subjects which trainees in real vehicle training, and reseach the road's running safe condition, and it is in favor of decrease the incidence of traffic accicent, and also have the advantages such as energy conservation,security,economy,highly effective etc.This paper mainly discuss the implemtation of automobile simulator driving system based on MCU and DirectX technology etc,mainly include the implemtation of scene system and simulation steer chair system,as well as the realize of data aquisitation and communication system between them.The simulation steer chair system are made of MCU control device, transducer vibration control device, manipulate control device.This paper mainly study the MCU control device and transducer vibration control device.Among others, the MCU control device with STC89LE516AD for kernel, assist with data acquisition circuit, data correspondence circuit etc, so we had completed the collection and correspondence of the steer information.The transducer virbrate device are made of transducers,AC machine and related machine device etc.Firstly,the steer signal are collected by MCU and count by dynamic model.Then send the movement data to the transducers and control the electric machine to control the related machine,thus,drive steer chair to move.The scene system are developed by 3DS MAX 7,VC++ and DirectX.Firstly,we use object-oriented technology and mathematical modeling, build the plan of all kinds of models in simulatior driving system.Secondly,through the object-oriented analysis to the automobile dynamic quality, based on the automobile dynamic quality and kinematic theory,we adopt the object-oriented modeling and mathematical modeling,then build the automobile dynamic quality models.According to the mathematical models of automobile dynamic quality,we build the automobile movement simulation models.Then we adopt Visual C++ as well as DirectX SDK program development software, and apply the function DirectX submitted,we complied the program of simulation driving system kinetic models and scene romance,when we import the 3D scene made by 3DS MAX 7,we finished the scene system. Though the expermential verification, it can well realize the requires of simulation driving systerm must possesssd to the scene system.
