The invention relates to a lane-changing early warning device based on vehicle-vehicle coordination as well as a vehicle-vehicle coordination lane-changing early warning method based on the device. The device comprises an information acquisition unit, an information communication unit, an information processing unit and an early warning output unit. According to the device and the method, the collision between two vehicles on the same lane in the same driving direction is predicted by virtue of the vehicle-vehicle communication, so that an initiative safety early warning is realized, errors in report of a visual sensor caused by factors such as light, environment and the like as well as the non-vehicle barriers such as laser sensor or radar sensor can be avoided, the initiative safety performance of the vehicle can be improved, the early warning information can be transmitted to more vehicles by means of vehicle-vehicle communication, and the initiative safety range of the vehicle can be enlarged.
