Method for Constructing Spatiotemporal Coupling Test Scenario

At present, the methods for generating basic test scenarios for autonomous driving are becoming more and more diversified. However, in the face of a huge number of basic test scenarios, there is no clear definition of how autonomous vehicles can effectively complete the test through the basic test scenarios. Based on the mutual coupling between the basic test scenarios, this paper defines the temporal coupling scenario and the spatial coupling scenario, and gives the definition of the spatiotemporal coupling test scenario on the basis of the two. By deploying the spatiotemporal coupling scenario to the autonomous driving virtual simulation platform, verifying that the spatiotemporal coupling scenario can improve the time efficiency of the test during the test of the autonomous vehicle.
