摘要
ADAS控制器主要通过传感器(如毫米波雷达、摄像头等)感知外界环境信息,并根据这些信息来决策车辆驾驶行为,以辅助驾驶员驾驶。随着汽车先进驾驶辅助系统(Advanced Driving Assistant System,ADAS)的快速发展,越来越多的ADAS功能被搭载在智能网联汽车上,如自动紧急制动(Autonomous Emergency Braking,AEB)、自适应巡航控制(Adaptive Cruise Control,ACC)等。目前针对ADAS控制器功能的测试方法主要是将其集成在整车上进行道路测试,这种测试方法效率较低,且难以实现危险、极限工况的复现,不能完整的评价控制器的功能。因此,本文提出一种基于ADAS控制器的虚拟测试方法,通过构建日常或极限的仿真测试场景,在短时间内完成大量的测试。
The principle of ADAS controller is that radar and camera are used as sensors to perceive the information of external traffic environment,and the controller decides vehicle behaviour to assist driving. With the rapid development of Advanced Driving Assistance System(ADAS), more and more ADAS functions will be mounted on intelligent connected vehicles, such as Automatic Emergency Braking(AEB), Adaptive Cruise(ACC), etc. At present, the main test methods for ADAS controller functions are to integrate it into the vehicle for field test, which the test method is inefficient and difficult to achieve the reproduction of dangerous and extreme scenarios, and the function of the controller can not be completely evaluated. This paper proposes a test method of ADAS controller based on virtual test, which can complete a large number of test scenarios in short time, and also can be tested in the environment of dangerous scenarios.
