Anti-collision system for automobile

Abstract

The invention discloses an anti-collision system for an automobile, and the system comprises a distance collection device, a control module, a warning module, and a braking module. The control module is electrically connected with the distance collection device, the warning module and the braking module. The distance collection device is disposed exactly in front of the automobile, and is used for collecting a distance between the automobile and a front barrier according to a preset collection period. The braking module is used for the braking of the automobile. The warning module is used for warning and prompting a driver. The control module is used for controlling the operation of the warning module and the braking module according to the collection information of the distance collection device. The system is simple in structure, is convenient to use, reminds the driver of danger when the automobile is in danger, actively carries out braking when the automobile is in a condition of no reaction, and avoids accidents.

Description

technical field [0001] The invention relates to the field of automobile electronics, in particular to an automobile anti-collision system. Background technique [0002] Automotive electronics is the general term for car body electronic control devices and vehicle electronic control devices. Car body electronic control device, including engine control system, chassis control system and body electronic control system (body electronic ECU).

The degree of automobile electrification is regarded as an important symbol to measure the level of modern automobiles. It is the most important technical me...

AI Technical Summary

Problems solved by technology

[0007] Some existing cars are equipped with anti-collision systems. The principle of anti-collision is based on one-way distance. For example, when the distance between the vehicle and an obstacle is less than a certain distance, it starts to warn or brake. However, this anti-collision consideration Blind spots exist because obstacles are not necessarily stationary. If the obstacle is a car, then there are two situations:

[0008] One situation is that the vehicle is in the same direction as the own vehicle, and if the relative speed of the two vehicles is very small, then it is undoubtedly inappropriate to warn or brake at this time;

[0009] Another situation is that the vehicle is in the opposite direction to the own vehicle, then the speed of the two vehicles is very large, and the warning or braking is based on the distance of one side, regardless of the braking distance and time of the other vehicle, it is very likely that there is no way to avoid collision
