| Abstract: | As the decision-making data collection module of intelligent vehicle, the perception system has a significant impact on the vehicle planning and control strategy. This paper analyzes the significant factors (rainfall, visibility and light intensity) of external natural conditions on the vehicle perception system, and forms the evaluation rules for the controllable technology of simulation environment and the controllable technology of real vehicle field test environment. In combination with relevant national standards and technical capacity reserves of the supplier, the rainfall simulation system covering light rain, moderate rain, heavy rain, heavy rain and heavy rain will be built; Build a fog fall simulation system covering a minimum visibility of 15-2000 meters; And build a four-gear adjustable natural lighting simulation system, so that the test site has the ability of all-weather, uninterrupted and controllable environmental testing. Based on the key functional testing research system of typical working conditions, the test case development and test of the intelligent vehicle perception system are carried out through the environment-controlled test technology. The test statistics show that the environment controllable test technology can effectively cover typical test scenarios, and can promote the realization of the highly automatic driving phase of intelligent vehicles. |
