Study on the construction of basic test scenario library of campus driverless vehicle

Aiming at the construction of driverless vehicle test scenario, this paper proposes a construction research of driverless vehicle test scenario library in campus environment. By analyzing the unique characteristics of the campus environment, the definition of different from the open/closed road test scenario is proposed. Combining with the characteristics of the scenario, the scenario elements are analyzed in layers. The combination analysis of scenario elements at different levels was carried out by using PICT(Pairwise Independent Combinatorial Testing) combination test tool, and random sampling method is used to extract different levels of sample sets. Through the analysis of scene elements and driving task complexity, this paper proposes a generation system of campus driverless vehicle combination test scenarios. According to the construction method of campus test scenario proposed, an obstacle avoidance test case is generated, and its simulation verification is carried out, the results show that the test vehicle can effectively decelerate and stop and avoid collision when encountering obstacles in front, which verifies the effectiveness of the test scenario.
