The invention relates to an auxiliary reversing method, device and system and a vehicle. The method comprises the steps that multiple pieces of historical position information of an obstacle in a moving state are acquired; based on the multiple pieces of historical position information of the obstacle, a future movement track of the obstacle is determined by utilizing a gradient descent algorithm;current movement direction information of the vehicle is acquired; based on the current movement direction information of the vehicle, a future movement track of the vehicle is determined; and basedon the future movement track of the obstacle and the future movement track of the vehicle, auxiliary reversing prompt information is formed. According to the technical scheme, the possible movement track of the obstacle in the future is estimated and guessed by utilizing the multiple pieces of historical position information of the obstacle, meanwhile, the possible movement track of the vehicle inthe future is estimated and guessed, and finally, based on the future movement track of the obstacle and the future movement track of the vehicle, the collision probability of the vehicle and the obstacle is judged, then auxiliary reversing prompt information is formed, safety accidents can be effectively prevented, and reversing safety is improved.
