Vehicle collision-proof early warning device

Abstract

The invention discloses a vehicle collision-proof early warning device, which is mainly and technically characterized in that the vehicle collision-proof early warning device comprises an image acquisition module, an image processing module, a millimeter microwave radar speed and distance measuring device, an ultrasonic sensor, a speed sensor, a brake sensor, an accelerator sensor, a steering sensor, a single-chip microcomputer and an early warning device, wherein the image acquisition module is used for acquiring information at the front of a vehicle and transmitting the information to the image processing module, the image processing module processes the information and then transmits the information to the single-chip microcomputer, the millimeter microwave radar speed and distance measuring device simultaneously transmits measured relative distance and relative speed between an ahead vehicle and the vehicle on which the vehicle collision-proof early warning device is installed to the single-chip microcomputer, the ultrasonic sensor transmits the measured speed of the vehicle on which the vehicle collision-proof early warning device is installed, the single-chip microcomputer processes the image information and the distance and speed data and then judges whether the vehicle is in a warning critical state or not, and finally a result processed by the single-chip microcomputer is displayed through the early warning device. The vehicle collision-proof early warning device has the advantages that the false warning rate of the early warning device is effectively reduced, the accidents such as rear-end collision are reduced and the transport efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile active safety, in particular to a vehicle anti-collision warning device. Background technique [0002] As a means of transportation for modern humans, automobiles have changed people's lifestyles, promoted the development of social economy and the progress of human culture, brought great convenience to people's lives, but at the same time brought serious traffic safety problems . According to the survey data of the Red Cross Society: the number of people who die in road traffic accidents in the world reaches 800,000 every year, and another 15-20 million people are injured, and the annual economic loss caused by road traffic accidents is about 558 billion US dollars. Road traffic accidents have brought huge losses to families, collectives and countries, and have become serious social problems in the world. [0003] At present, my country's road conditions are constantly improving, and the aver...

Problems solved by technology

The problem with this method is that it is impossible to accurately analyze the front view of the vehicle, and the acquisition of video images is easily affected by weather factors, resulting in large errors, and it is impossible to accurately warn the driver.

Therefore, although they have helped people to judge the distance between vehicles to a certain extent, there is a larger false alarm rate, and the larger false alarm rate will seriously damage the comfort and safety awareness of vehicle drivers and passengers.
