The invention discloses a multi-vehicle coordination collision avoidance system and method based on vehicle-vehicle communication, and belongs to the field of vehicle active safety. The system comprises an information collection module, a communication module, an information processing module, and a voice prompt module. The method provided by the invention comprises the steps: collecting the movement data of a target vehicle and a front vehicle in real time through the information collection module, comparing the safety distance of the target vehicle with the distance from the target vehicle to the front vehicle, and judging the danger state of the two vehicles; and starting to judge whether the target vehicle and the front vehicle meet a coordination collision avoidance condition of two vehicles or not when a danger signal is received. When the target vehicle and the front vehicle meet the coordination collision avoidance condition, the time of coordination collision avoidance of the two vehicles and the expected speed are calculated, and are transmitted to other coordination collision avoidance vehicles, thereby achieving a purpose that the vehicles at the same lane achieve the expected speed in a collision time range and move at a constant speed, and achieving the coordination collision avoidance.read more
