Abstract:

An automatic emergency braking (AEB) pedestrian detection system was developed for automotive active safety technology. The AEB pedestrian detection system includes a soft dummy target, a dummy driving device and a control system with driving the dummy to walk according to the requirements of the AEB pedestrian test scenario of the 2018 Chinese New Car Evaluation Procedure (C-NCAP), with real-time communicating a driving robot which controls the test vehicle. Some measurements were done for walking distances of the dummy target, walking speeds of the dummy target, and linkage experiments with the driving robot. The results show that the success rate of the system is more than 90%, while the accuracy of the dummy speed control is 96%, and the collision location accuracy is 96%. Therefore, the AEB pedestrian detection system can be used to conduct C-NCAP (2018) pedestrian test experiments both to evaluate a vehicle AEB system functions and to be a tool for related product developing since the system can accurately restore current hazardous conditions.
