Reverse driving assistant anti-collision system and method for automobile

Abstract

The invention discloses a reverse driving assistant anti-collision system and a method for an automobile, which relate to the technical field of automobile safety. The system comprises a target acquisition module used for acquiring automobile and pedestrian information on the rear part and the side rear part of the automobile, and calculating to obtain a target traveling track when judging a target to be effective; an automobile status information acquisition module used for acquiring status information of the automobile and calculating to obtain a reverse driving track of the automobile; a central control unit used for judging whether the reverse driving track of the automobile intersects the target traveling track or not, and controlling an execution unit to prevent automobiles from colliding when judging intersection exists and the automobile colliding time is less than a predefined threshold; and the execution unit used for reminding a driver to drive safely or / and brake the automobile. The invention further provides the corresponding method. The detection range of the target on the rear part and the side rear part of the automobile is effectively enlarged, and meanwhile, pedestrians can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a backing assist anti-collision system and method for vehicles. Background technique [0002] With the increase of the number of vehicles, the probability of traffic accidents is also increasing, especially in the process of vehicle reversing, because it cannot effectively detect the vehicles passing by quickly in the lateral direction or the pedestrians passing quickly, thus greatly increasing the traffic accident risk. Collision probabilities between vehicles and pedestrians. [0003] At present, in order to reduce the probability of the above-mentioned accidents, vehicle manufacturers install a reversing radar detection device behind the vehicle to monitor the target behind the vehicle. When the vehicle is in danger of collision, it will automatically warn the driver to drive safely. Therefore, to a certain extent avoid collision accidents. [0004] However, the area ...

AI Technical Summary

Problems solved by technology

[0004] However, the area behind the vehicle that can be detected according to the above method is small, and it is not sensitive to the detection of moving objects, so it cannot completely avoid collisions with surrounding vehicles. At the same time, this method cannot identify pedestrians passing laterally to protect pedestrians.
