Driving vehicle collision early-warning method and device

Abstract

The invention discloses a driving vehicle collision early-warning method and a driving vehicle collision early-warning device. The driving vehicle collision early-warning method comprises the steps of: acquiring position information and driving information of a local vehicle, and receiving position information and driving information broadcasted by a remote vehicle within a preset distance of the local vehicle; generating a local prediction driving trajectory of the local vehicle in a preset duration from the present moment according to the local position information and the local driving information; generating a remote prediction driving trajectory of the remote vehicle in a preset duration from the present moment according to the remote position information and the remote driving information; judging whether the local prediction driving trajectory and the remote prediction driving trajectory have a trajectory intersection point or not; and outputting preset collision early-warning information if the local prediction driving trajectory and the remote prediction driving trajectory has the trajectory intersection point. The driving vehicle collision early-warning method and the driving vehicle collision early-warning device provided by the invention have the advantages of being free from the limitation of the field of view in the process of acquiring the position information and the driving information, high in accuracy rate of acquired information, low in cost, capable of forming real-time effective early warning and improving the road traffic safety.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation system and automobile safety, in particular to a method and device for early warning of vehicle collision. Background technique [0002] With the rapid development of the traffic industry, the number of road vehicles has increased sharply, and the traffic safety situation has become increasingly severe, especially at intersections with complex traffic conditions. Drivers have blind spots, and their driving collision rates are often higher, causing serious damage to the personal safety of drivers and passengers. Great threat. [0003] In recent years, with the development of communication technology, advanced driver assistance systems (ADAS, Advanced Driver Assistance Systems) have emerged. This system uses image recognition to judge the safety status of vehicles and give timely warnings to avoid traffic accidents. However, due to Affected by factors such as the installation pos...
