Abstract

The invention discloses a vehicle early warning method comprising: acquiring the speed of a current vehicle, the distance from the current vehicle to a front vehicle, the speed of the front vehicle, and the fatigue degree of a current vehicle driver, wherein the front vehicle is located in front of the current vehicle; determining the safe distance between the current vehicle and the front vehicle based on the speed of the current vehicle, the speed of the front vehicle, the fatigue degree of the current vehicle driver, and a safety vehicle distance model; and outputting warning information when the distance between the current vehicle and the front vehicle is less than the safety distance. The vehicle early warning method fully takes account of the fatigue state of the driver when the safety distance is determined, so that the output early warning is more accurate and the accuracy of the vehicle early warning is improved.

Description

technical field [0001] The invention relates to the technical field of driving safety, in particular to a vehicle early warning method, device and system. Background technique [0002] At present, considerable exploration has been carried out at home and abroad in preventing lane departure and maintaining a safe distance, and some breakthroughs have been made. At present, monocular vision technology is widely used in Forward Collision Warning System (FCW) to ensure driving safety. [0003] Monocular vision technology is: use a camera to collect road images and images of vehicles in front, and realize road detection and distance measurement based on the collected images. [0004] The forward collision warning (Forward Collision Warning, FCW) system can monitor the vehicle in front, judge the distance, orientation and relative speed between the vehicle and the vehicle in front, and warn the driver when there is a potential danger. The FCW system itself does not take any brak...
