摘要/Abstract

摘要： 为验证车辆高级驾驶辅助系统（ADAS）功能在复杂电磁环境下的可靠性，并考虑到目前缺乏符合 ISO 11451-2 的测试方法，文章提出了一种基于整车在环的 ADAS 电磁辐射抗扰度的测试平台和测试方法。针对车辆 ADAS 功能的电磁辐射抗扰度测试开发了测试平台，并基于小孔成像原理和雷达模拟器完成对摄像头、雷达传感器的校准以及传感器场景融合的验证，实现了车辆的车道偏离警告（LDW）、包含多目标的自适应巡航控制（ACC）以及盲区监测（BSD）等工况在半电波暗室内的成功激活。最后对 ACC 功能进行电磁辐射抗扰实验，当场强至 98 V/m 时，车辆 ACC 功能退出。结果表明，所提出的测试方法和测试平台对 ADAS 的电磁辐射抗扰度测试是可行和有效的。

Abstract: To verify the reliability of advanced driving assistance system (ADAS) functions in complex electromagnetic environments and taking into account the current lack of ISO 11451-2 compliant test methods, this paper proposes an ADAS electromagnetic radiation immunity test platform and test method for ADAS electromagnetic immunity based on vehicle hardware-in-loop concept. And develops an ADAS electromagnetic radiation immunity test platform for electromag netic immunity test of vehicle ADAS function. Based on the principle of small-hole imaging and radar simulator, the calibration of camera and radar sensor and the verification of sensor scene fusion are completed, The vehicle's lane departure warning (LDW), adaptive cruise control (ACC) with multiple targets, and blind spot detection (BSD) and other conditions were successfully activated in the semi-anechoic chamber. ACC is successfully activated in the semi-anechoic chamber. Finally, electromagnetic radiation immunity test is carried out on ACC function. When the spot force reaches 98 V/m, the ACC function of the vehicle is withdrawn. The results show that the proposed test method and test platform are feasible and effective for the electromagnetic radiation immunity test of ADAS system.
