Application Research on Driving Simulator for Automatic Driving System

The testing phase of autonomous driving vehicles before they are actually on the road is a crucial part.A low-cost,high-efficiency and high-precision test method for autonomous vehicles is of great significance for the development of autonomous driving vehicles.Applying the driving simulator to the research of autonomous vehicle testing has become a research hotspot in recent years.Based on the detection of the autonomous driving vehicle of the virtual driving scene,the combination application of the driving simulator and the virtual driving scene is carried out to test the autonomous driving vehicle through the background vehicles,pedestrians,traffic lights,buildings,indicating signs and the like of the virtual driving scene.The typical traffic scene is designed,and the performance indicators of autonomous driving vehicle are studied through the real-time interaction between the autonomous driving vehicle and the background vehicle.The research results show that the driving simulator can highly fit the human driving experience.The driver can control the background driving vehicle through the driving simulator to simulate the driving behavior in real life,which can promote the simulation test of the autonomous driving vehicle.
