VEHICLE TO PEDESTRIAN (V2P) COLLISION PREVENTION SYSTEM AND METHOD THEREFOR

摘要

A vehicle to pedestrian (V2P) collision prevention system and a method therefor are disclosed. In a V2P communication system for transmitting and receiving vehicle global navigation satellite system (GNSS) location information and pedestrian GNSS location information via wireless access in vehicular environments (WAVE) standard wireless communication, a V2P collision prevention system comprises: an on-board unit (OBU) in which a V2P collision prevention service is executed by calculating a relative distance between the vehicle and the pedestrian and which is mounted in the vehicle, road side equipment (RSE) which is capable of WAVE standard wireless communication with the OBU, and a user terminal which is capable of transmitting the pedestrian GNSS location information via WAN/Internet; and a server which calculates the possibility of collision between the vehicle and the pedestrian using the vehicle GNSS location information and the pedestrian GNSS location information via the RSE and WAN/Internet, and which transmits a danger signal to the driver of the vehicle and to the user terminal of the pedestrian. According to the present invention, the OBU provides a V2P collision prevention service via WAVE by calculating the relative distance between the vehicle and the pedestrian even when the accuracy of locations measured using the vehicle GNSS and measured using the pedestrian GNSS is low, and the latency executed using an ACK packet between the vehicle and the server, and between the pedestrian and the server is low.
