Automobile collision avoidance method based on width detection

Abstract

The invention discloses an automobile collision avoidance method based on width detection. The automobile collision avoidance method based on width detection includes the steps that initialization is carried out, an angle of the detection direction of a first distance detector and an angle of the detection direction of a second distance detector which are arranged at the position of the distance L between the two sides of the center position of an automobile head of an automobile are calibrated, and the adjustable angle range is pre-demarcated, wherein the first distance detector comprises a first sub-distance detector and a second sub-distance detector, the second distance detector comprises a third sub-distance detector and a fourth sub-distance detector, and the edge parameters of front driving space are detected through the first sub-distance detector, the second sub-distance detector, the third sub-distance detector and the fourth sub-distance detector; the width of the driving space is calculated, alarm is given, and the driving direction of the automobile is adjusted according to the detected width value; by means of the driving space step, it is achieved that the width of the driving space is prejudged in advance, collision is prevented, the driving skill of a driver is effectively improved, and the probability of accident occurring is reduced.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to an automobile collision avoidance method based on width detection. Background technique [0002] During the driving process of the car, collision accidents between the car and the front and rear vehicles, or with the surrounding environmental facilities often occur. Accidents will not only cause damage to vehicles and collision objects, but also cause economic losses, and sometimes cause injuries to drivers and passengers. Therefore, it is of great significance to effectively avoid accidents. [0003] At present, the early warning of accidents is usually realized by means of radar detection, reversing images, etc., and an alarm is issued by detecting or displaying surrounding obstacles to remind the driver. However, most of these methods can only be implemented under certain conditions. For example, the radar only starts to alarm within a certain detection range, and the reversi...
