The Implementation And Research Of Driving Simulation System Based On Unity 3D

With the development of automobile safety technology,the research on the active safety technology which is based on the driver as the research object is also deepening.Based on the driver's behavior of the active safety technology,it can enhance the safety performance of the car further on the foundation of original car,and can protect the safety of occupants better.At the same time,urban crowded road traffic has become a serious problem,and the emergence of the concept of car network ing can achieve the communication of vehicle-vehicle,vehicle-road and vehicle-people,alleviating road traffic congestion of the problem greatly,enhancing the traffic capacity of road traffic.Therefore,it is of great value to study the active safety technology of driver and virtual simulation driving process based on vehicle networking technology.It can provide the necessary data support and theoretical support for the in-depth research of active safety technology and intelligent transportation vehicle network.This paper is to develop a simulation platform based on Unity 3D in order to study active safety and vehicle network.After fully studying the principle and process of building a virtual scene in Unity 3D,the virtual scene of the simulated driving platform is built,including the modeling of terrain,road and environment,the modeling and control o f the driver's driving vehicle,modeling AI vehicles and controlling the traffic rules in a virtual scene on a fixed road network.After examining and analyzing the mainstream active safety research direction and the collection method of driver information data,several specific virtual experiment scenarios are built on the simulated driving platform for different experimental purposes.These scenarios include the following model,the overtaking model,the emergency collision model and the multiplayer network simulation driving scene.In order to collect all the effective information including the environment,the driver and the vehicle in the experiment,a complete information acquisition system is built on the simulated driving platform,including the vehicle dynamic parameter information acquisition system,the driver's facial information acquisition system and driver EEG signal acquisition system.The driving simulator can simulate the driver's real driving process by experimenting on the virtual simulation driving platform with the background of driving and the realistic virtual driving scene.At the same time,through the information collection system building on the driving platform,all the necessary information data can be accurately and completely collected including the environment,the vehicle and the driver in the simulated driving process.These data can be used as the data support for the research process.
