汽车紧急制动行人检测系统的设计与测试

Design and Test of Pedestrian Detection System for Emergency Braking in Automobile

针对有行人出现时汽车自动紧急制动(AEB)测试需求,设计了一种行人检测系统。该系统主要包括假人目标、假人驱动装置以及控制系统,可以根据中国新车评价规程C-NCAP的AEB行人测试场景要求,驱动假人目标按规定的路线移动,并与测试汽车的驾驶机器人实现互联互通。为验证所设计的行人检测系统的有效性,进行了假人目标移动位移、移动速度和驾驶机器人的协同测试。测试结果表明,该行人检测系统的一次成功率达到90%以上,假人速度控制的精度达到96%,假人与测试汽车的碰撞位置准确度达到96%,可以模拟行人出现时的汽车紧急制动场景。该AEB行人测试系统可以用于C-NCAP行人测试,在汽车AEB功能测评中得到应用,具有较强的实际应用价值。

A pedestrian detection system mainly including dummy target,dummy drive device and control system was designed for automatic emergency braking(AEB)test in the presence of pedestrians.The dummy target was operated to move along the prescribed route according to the AEB pedestrian test scene requirements of China New Car Evaluation Regulation(C-NCAP),and interconnection with the driving robot of the test vehicle was achieved.To verify the effectiveness of the pedestrian detection system,the moving displacement,moving speed and driving robot of the dummy target were tested.The test results show that the first success rate of the human detection system in this line reaches more than 90%,that the accuracy of the dummy’s speed control reaches 96%,and that the accuracy of the collision position between the dummy and the test vehicle reaches 96%.And the test also indicates that the emergency braking scene of the vehicle can be simulated when the pedestrian appears and that the AEB pedestrian testing system can be used for C-NCAP pedestrian testing and applied in automotive AEB function evaluation with strong practical application value.
