1. A vehicle driving detection method, performed by an electronic device, and the method comprising:
obtaining first image data corresponding to a driving direction of a first vehicle;
performing lane line detection processing on the first image data to determine that the first vehicle is traveling along a first lane of at least two lanes;
performing image recognition processing on the first image data to detect that a second vehicle travels on the first lane within a preset distance in front of the first vehicle;
performing speed measurement processing on the second vehicle to obtain a first speed of the second vehicle;
determining, when the first speed is less than a minimum speed limit of the first lane, the second vehicle as a potential slow vehicle;
obtaining second image data corresponding to the driving direction of the first vehicle after a preset duration;
performing image recognition processing on the second image data to determine that the second vehicle still travels on the first lane within the preset distance in front of the first vehicle;
re-performing speed measurement processing on the second vehicle to obtain a second speed of the second vehicle;
generating slow vehicle warning information when the second speed is less than the minimum speed limit of the first lane;
backtracking a historical congestion event according to the slow vehicle warning information, to determine that the second vehicle is a frontmost slow vehicle traveling on a same lane as the first vehicle within the preset distance in front of the first vehicle; and
transmitting, by a processor, slow speed indication information to a terminal of the second vehicle when the second vehicle is the frontmost slow vehicle traveling on the same lane as the first vehicle within the preset distance in front of the first vehicle, the slow speed indication information being used for instructing the second vehicle to travel into a slow lane or speed up in an original lane to mitigate an impact of the second vehicle on one or more vehicles behind the second vehicle in the first lane.
