Virtual Driving Scenario Simulation can be completed on a virtual prototype and thousands of tests can be completed within the time and budget required for a single physical test.This greatly promotes the development of unmanned driving technology.In this paper,a virtual racetrack was built by Prescan software,which referenced the geometric parameters of Xiangyang Dream Race Track and the Bistu-Ⅲunmanned Formula car prototype was built by Carsim software.Subsequently,associated simulations of virtual tests were carried out based on Prescan/Simulink/Carsim software and the simulation of straightway accelerating,skidpad and lap time racing were realized.It was shown that this Virtual Driving Scenario Simulation system can meet the requirements of simulation tests on racing i-tems and can verify the performance of the environmental perception sensors of unmanned Formula cars.
