Pre-warning system for preventing tailgating of rear vehicle

Abstract

The invention relates to a pre-warning system for preventing tailgating of a rear vehicle. The pre-warning system comprises a signal collecting mechanism, a data processing mechanism and a pre-warning executing mechanism, wherein the signal collecting mechanism, the data processing mechanism and the pre-warning executing mechanism are installed on a current vehicle. The signal collecting mechanism is used for sending detecting waves backwards and receiving the detecting waves reflected by the rear vehicle, so that relative speed and the distance between the two vehicles of the rear vehicle and the current vehicle are monitored. The data processing mechanism is connected with the signal collecting mechanism, and whether a tailgating danger exists between the rear vehicle and the current vehicle or not is judged according to a preset condition on the basis of the relative speed and the distance between the two cars fed back by the signal collecting mechanism. The pre-warning executing mechanism is connected with the data processing mechanism, and pre-warning to a driver of the rear vehicle and / or the current vehicle is executed according to the judging result fed back by the data processing mechanism. The pre-warning system for preventing tailgating of the rear vehicle is capable of reminding the rear vehicle that the distance between the two vehicles is small and a safe interval needs to be kept and reminding the driver of the current vehicle that the rear vehicle is in an unsafe distance and behaviors such as braking need to be avoided as far as possible.

Description

Technical field [0001] The invention relates to the technical field of automobiles, and in particular to a rear-end collision prevention early warning system that reminds vehicles behind to maintain a safe speed and distance. Background technique [0002] With the rapid development of society and economy, the number of cars has continued to increase. While it brings convenience to human society, it also causes traffic accidents to increase year by year. According to statistics released by the Ministry of Public Security of China, in 2011, a total of 210,812 road traffic accidents involving casualties were reported nationwide, resulting in 62,387 deaths. Traffic accidents have become the number one public hazard in modern society. [0003] Among various types of traffic accidents, rear-end collisions are one of the main forms of traffic accidents. When two motor vehicles are driving in the same direction, the rear vehicle is responsible for keeping a safe distance from the precedin...
