Embedded Intelligent Brake Early Warning System

Abstract

The invention discloses an embedded intelligent brake early warning system, comprising an oil pressure sensor module, a displacement sensor module, an embedded microprocessor module, a key input correction module, an LED driving module, an LED light group and a display module. The system can characterize the strength of the foot on the brake according to the oil pressure in the brake hose or the displacement of the brake pedal, and warn the rear car in real time through the tail light; the displacement of the brake pedal and the oil pressure range in the brake hose can be corrected by pressing the button to avoid different Inaccurate display of brake lights in driving conditions. Based on the embedded intelligent brake warning system, compared with the existing ordinary brake system, it solves the problem that only the braking status can not indicate the braking degree. The occurrence of traffic accidents. At the same time, the measurement method and control method are optimized to provide our car with a safe, precise and intelligent braking state warning system.

Description

technical field [0001] The invention relates to an automobile braking system, in particular to an embedded intelligent braking state display system. Background technique [0002] At present, the braking system used by the vast majority of vehicles can only display to the rear vehicle that the vehicle is in the braking state, and cannot display whether the vehicle is under normal braking or emergency braking. accurate judgment. Especially in the process of high-speed driving, the front and rear speeds are relatively fast. When the car suddenly brakes in an emergency, the driver of the rear vehicle can only rely on the two information of the front brake light and the distance to the front vehicle. Judging whether emergency braking should be taken, but it may be due to the relatively fast speed, the vehicle behind cannot take action or the judgment is wrong, which may cause the vehicle to collide. [0003] Chinese Patent No. 02246690.8 discloses a vehicle brake force display ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an embedded intelligent brake warning system to solve the problem of the general automobile brake display device proposed in the above-mentioned background technology, which directly connects the brake pedal to the power circuit of the brake light. Through the contact of the brake light power switch, the brake light is on. This brake device can only reflect whether it is in the braking state, but cannot display the strength of the car brake or the pedal. It also solves the problem of using a displacement sensor to measure the displacement of the brake pedal to display Disadvantages of braking force, as the thickness of the brake pad changes, the displacement of the brake pedal also changes, resulting in inaccurate display results and other problems, which cannot well meet people's needs
