The Research Of The Automobile Driving Training Simulator System Design

With the development of new energy vehicles and small cars,the rigid requirements of private car is growing and car driving gradually transformed from a career as a skill.The demand for driver training keeps increasing and safe driving has become a traffic safety focus.Besides the impact of space,time,weather and other factors,driving simulation training system provides scientific and standardized operation of demonstration and guidance to improve the efficiency and quality of training.Driving simulation training system is based on the purpose of driving training and uses virtual reality technology as a means to achieve active analog system.This paper studies the design method for driving simulation training system,and takes road driving as a case.(1)Take system design theory as a guide and propose the three-dimensional design method,which uses virtual reality technology to simulate the activities of driving training,from the target activity,technology,and human-machine interface technology to achieve three levels of system design respectively.(2)Based on the activities centered design method,elements and level of activity are analyzed;and combined with cognitive psychology theory,a training activities simulator model is made;depending on the characteristics of road driving scene and driving behavior model,road driving training activities are modeled.(3)Use the object-oriented modeling technology to model the system from the technical level.The technology model is set up by the manipulation of simulation system,dynamic simulation system,visual simulation system,subsystems operating reviews system and audio management system.And the paper studies the key technologies of road driving training,analyzes the procedure of setting up the virtual road scenes,constructs the driving operation mode and driving operation evaluation,which is based on hierarchical task network,and studies camera management system.(4)Combined with the multi-aware interface features and immersion and the flow theory,the haptic,visual and immersive experience immersive man-machine interface design principles are proposed.And the immersive design principles of road driving training system are proposed,which include the stage of intent,the story of the goal,the visual operation,and clearly stated navigation.Finally,the paper uses the game engine Unity3 D systematically develop the simulator system,explain the development of processes from the building of visual scene and the logic of the programming code.Also the study takes the physics engine,image rendering,particle system,and the script as example to show the instantiated development of simulation system.Practice has proved that three-dimensional design method can effectively guide the design of the car driving simulation training system to unify the active,technology and human-machine interface,which takes the system design with the use of virtual reality technology to simulate activities,training and other applications like systems design skills with a draw and forward-looking.
