Automobile rear-end collision early warning apparatus and method

Abstract

The invention provides an automobile rear-end collision early warning apparatus and method, wherein the apparatus comprises an information acquisition module, a communication module, a micro-control module, and an alarm and brake module; the information acquisition module and the communication module are connected with the signal input end of the micro-control module; and the alarm and brake module is connected with the signal output end of the micro-control module. According to the automobile rear-end collision early warning apparatus and method, brake information of the lead automobile and front obstacle information can be obtained timely through the communication module, and the obtained information can be processed through a microprocessor, therefore, the following automobile can decelerate timely, and rear-end collisions can be reduced.

Description

Technical field [0001] The invention relates to a vehicle intelligent auxiliary driving device, in particular to a vehicle rear-end collision prevention early warning device and method based on workshop communication. Background technique [0002] With the rapid development of my country’s economy, the number of car ownership has increased rapidly, and the demand for car drivers has increased, but the driving level of car drivers is different; at the same time, due to insufficient driver training and supervision, a large number of low driving skills have been generated The driver. The increase in road vehicles, the deterioration of the driving environment, and the lack of driving skills of many drivers, which makes vehicle rear-end accidents often occur; and in the case of multi-vehicle following, even drivers with high driving skills still follow the car The problem of inaccurate judgment of distance and vehicle braking, especially the sudden acceleration and deceleration of the...

AI Technical Summary

Problems solved by technology

The number of road vehicles increases, the driving environment deteriorates, and there are many drivers with insufficient driving skills, which makes vehicle rear-end collision accidents occur frequently; and in the case of multiple vehicles following, even drivers with high driving skills may follow The problem of inaccurate judgment of distance and vehicle braking, especially the sudden acceleration and deceleration of the vehicle. In this case, if the following distance and speed cannot be well controlled, it is very easy to cause rear-end collision accidents, especially leading to serial rear-end collisions of accompanying vehicles ACCIDENT
