Traffic in-loop automatic driving simulation system

Abstract

The invention discloses a traffic in-loop automatic driving simulation system, which can acquire transmitted real roads and traffic data according to an Internet of Vehicles technology, and constructa first simulation traffic scene according to the real roads and the traffic data so as to ensure the authenticity of the first simulation traffic scene. And on the basis, the system constructs the virtual tested vehicle and the state data thereof, the virtual tested vehicle and the state data thereof are fused into the first simulation traffic scene to obtain a virtual traffic scene, and the virtual tested vehicle is controlled to automatically drive and timely update the virtual traffic scene according to the virtual traffic scene so as to complete interactive simulation of the virtual traffic scene and the virtual tested vehicle. The authenticity and the accuracy of a simulation result in a simulation test can be ensured.

Description

technical field [0001] The present application relates to the technical field of Internet of Vehicles, in particular to a traffic-in-the-loop automatic driving simulation system. Background technique [0002] The verification and testing of the automatic driving system is one of the important links in the research and development of automatic driving technology. At present, the commonly used testing methods for automatic driving systems are mainly divided into two categories, namely real vehicle testing and simulation testing. [0003] Real vehicle testing, that is, using real vehicles to deploy the automatic driving system and testing on real roads (closed roads or open roads). This method uses real vehicles and occupies real roads, so the test cost is relatively high, and it has certain test risks (traffic accidents), and the accumulation of test data is slow. [0004] Another method is the simulation test, that is, in the computer system, the vehicles, roads and traffic...
