Abstract

The invention is applicable to the technical field of automobile control, and provides an automobile driving assistance method and device. The automobile driving assistance method comprises the steps of detecting the distance between the current position of an automobile and intersection traffic lights, acquiring the type of a turn-on light in the traffic lights and the remaining turn-on time when the automobile is detected to arrive at a position which is a preset distance away from the traffic lights, when the turn-on light is a green light, determining the speed required by passing the intersection before the red light is turned on according to the preset-distance position and the remaining turn-on time, and executing a corresponding driving assistance operation when the required speed exceeds preset intersection safety speed, thereby providing corresponding driving assistance operations for a driver so as to drive the automobile to pass the intersection safely, being capable of effectively reducing the occurrence rate of red light running of automobiles, and improving the traffic safety of the intersection.

Description

technical field [0001] The invention belongs to the technical field of automobile control, and in particular relates to an automobile driving assistance method and device. Background technique [0002] At present, the traffic lights at intersections are composed of red lights, green lights, and yellow lights. Wherein, red lights represent prohibition of passage, green lights represent permission to pass, and yellow lights represent warnings. Among the current national road traffic accident statistics, road traffic accidents involving casualties by running a red light account for a relatively large proportion. Specifically, according to the national road traffic accident statistics, as of January to October this year, the national road traffic accident statistics Figures show that there were 4,227 road traffic accidents involving casualties across the country caused by running a red light, resulting in 798 deaths, making it difficult for traffic lights to play a role in direc...
