Research on pedestrian vehicle collision warning based on path prediction

The vehicle FCW (forward collision warning) system is supposed to considerable reduce the traffic accidents caused by pedestrian crossing. The pedestrian path prediction method in FCW is studied, and the five-freedom-degree vehicle model is analyzed, the limit condition where whether the maximum barking acceleration can avoid collision effectively is researched. The vehicle coordinate is divided according to the psychological safety distance of pedestrians, and an anti-collision warning system is designed on basis of the pedestrian initial position, the movement speed and path. The test results show that the designed anti-collision warning system can effectively warn the driver before the collision accident occurs and avoid pedestrian traffic accidents caused by the negligence of the drivers.
