Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and device for digital twin virtual-real multi-vehicle mixed traffic simulation. Background technique [0002] The intelligence and networking of cars is the major trend in the development of the automotive industry today. Compared with traditional driver-driven cars, intelligent networked cars have great advantages in improving traffic efficiency. Before the commercialization of intelligent networked vehicles, a large number of experimental verifications of related technologies or algorithms are required to ensure safety. However, real vehicle experiments are often expensive and have many limitations, so simulations are often performed before real vehicle experiments. [0003] Currently commonly used autonomous driving simulation software includes CarSim, Prescan, Carla, etc. These software or platforms have good characteristics in vehicle dynamics mo...
