AI Technical Summary
Technical Problem
The reversing process is highly dependent on the driver's subjective judgment and driving experience, resulting in greater safety hazards.
Method used
Under the vehicle's reversing operation, dynamic obstacle information behind the vehicle, including interference distance, is obtained, and the target vehicle speed is determined based on this information. The target vehicle speed is positively correlated with the interference distance, and the vehicle speed is controlled through the control module.
Benefits of technology
It realizes stable control of vehicle speed under reversing conditions, avoids excessive speed during reversing, reduces the risk of collision with dynamic obstacles, and effectively reduces safety hazards.

Abstract
The invention relates to the technical field of vehicle control, in particular to a reversing control method and system and a vehicle, and the method comprises the steps that under the reversing working condition of the vehicle, dynamic obstacle information behind the vehicle is obtained, the dynamic obstacle information comprises the interference distance, and the interference distance refers to the distance between a target point and the tail of the vehicle; the target point refers to an intersection point between the predicted motion path of the vehicle and the predicted motion path of the dynamic obstacle; based on the dynamic obstacle information, a target vehicle speed is determined, and the target vehicle speed and the interference distance are in positive correlation; controlling the speed of the vehicle based on the target vehicle speed; according to the method, the speed of the vehicle can be stably controlled under the backing-up working condition, the vehicle speed is prevented from being too high in the backing-up process, the risk of collision with dynamic obstacles is reduced, and therefore potential safety hazards are effectively reduced.
