Abstract

The invention discloses an expressway-oriented vehicle-road cooperation automatic driving simulation test system and method, and the system comprises a real physical unit system, a virtual reality test system, and a communication network system which is used for providing data communication and network transmission between the real physical unit system and the virtual reality test system. The real physical unit system comprises an intelligent network connection test vehicle, a closed test site road and an expressway roadside intelligent facility, and the virtual reality test system comprises an expressway map acquisition module, a terrain environment construction module, a vehicle twinborn module and a traffic scene module. The vehicle twinning module has a function of converting latitude and longitude coordinates of the intelligent network connection test vehicle in a closed test site road into coordinates of a twinning vehicle in an expressway terrain environment. According to the simulation test system, highway road test is replaced by closed test site road and virtual simulation test software test, the defects of real vehicle on-road test can be completely overcome, a large amount of financial resources and manpower can be saved, the efficiency is high, and the safety can be guaranteed.
