Abstract

The invention discloses a dangerous driving behavior recognition and dangerous event prediction method and device, equipment and a medium. The method comprises the steps that dynamic driving data of avehicle at the current moment are collected; acquiring a dangerous driving characteristic value at the current moment according to the dynamic driving data; acquiring historical driving data of the vehicle in a specified historical time period; acquiring a driving behavior characteristic value according to the historical driving data; and comparing the dangerous driving characteristic value withthe driving behavior characteristic value to obtain a comparison value, comparing the comparison value with a preset threshold value to determine whether the vehicle is currently in a dangerous driving behavior or not, and predicting the probability of a dangerous event. According to the invention, under the condition that certain driving data is collected and stored in advance, dangerous drivingcan be quickly identified and warned without increasing high hardware cost, and dangerous driving behaviors can be quantitatively identified.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving, in particular to a dangerous driving behavior identification and dangerous event prediction method, device and storage medium. Background technique [0002] Dangerous driving can easily lead to car accidents. Car accidents are one of the most dangerous killers of human beings. Millions of people die every year around the world. In China alone, about 100,000 people die in car accidents every year. With the development of society and the advancement of science and technology, the application of semi-automatic driving and automatic driving technology is becoming more mature, and the equipment for collecting vehicle driving data is becoming more and more diverse. [0003] Although technologies such as assisted driving and automatic driving are gradually entering people's field of vision, people use more and more sensors to collect data in automotive technology. Whether it is the d...
