车道偏离报警和前撞报警是驾驶员辅助系统的两个重要组成部分,报警的正确率、误报率和漏报率不仅是评价系统性能优劣的重要指标,也是影响驾驶员对辅助系统主观感受的重要原因。使用NI公司的开发工具,设计和搭建了报警性能测试台架,能够将与实车采集的道路视频影像信息时间同步的车辆状态信息融合作为测试样本,回放给待测的驾驶员辅助系统,进行硬件在环仿真测试,人工对比实际行车状况判定报警是否相符合样本中的实际道路环境,形成测试结果分析报告。最后,通过实验初步验证了该测试台架的有效性。
車道偏離報警和前撞報警是駕駛員輔助繫統的兩箇重要組成部分,報警的正確率、誤報率和漏報率不僅是評價繫統性能優劣的重要指標,也是影響駕駛員對輔助繫統主觀感受的重要原因。使用NI公司的開髮工具,設計和搭建瞭報警性能測試檯架,能夠將與實車採集的道路視頻影像信息時間同步的車輛狀態信息融閤作為測試樣本,迴放給待測的駕駛員輔助繫統,進行硬件在環倣真測試,人工對比實際行車狀況判定報警是否相符閤樣本中的實際道路環境,形成測試結果分析報告。最後,通過實驗初步驗證瞭該測試檯架的有效性。

The important parts of driver assistance systems are lane departure warning and front collision warning.The warning’s accuracy rate and error rate and missed rate are not only the important indicators for evaluating the performance of DAS,but also the important reasons of affecting the driver’s subject feelings for DAS.For evaluating the warning’s performance a test bench is designed and built,using the NI development tool,which can combine the real road video data with time-synchronized vehicle status information to a test sample,and replayed the test sample to DAS for hardware in loop simulation testing,and then determined the character of warning if it was in line with the actual road environment.After that a test report was finished by test system.Finally,it preliminary verified the validity of the test bench with an experiment.
