Embedded intelligent brake early warning system

Abstract

The invention discloses an embedded intelligent brake early warning system. The intelligent brake early warning system comprises an oil pressure sensor module, a displacement sensor module, an embedded microprocessor module, a key input correction module, an LED driving module, an LED lamp set and a display module. The system can represent the brake stepping force according to the oil pressure in a brake oil pipe or the displacement of a brake pedal, and warns a rear vehicle in real time through a tail lamp. The displacement of the brake pedal and the oil pressure range in the brake oil pipe are corrected through the key, and the situation that display of the brake lamp is not accurate under different running vehicle conditions is avoided. Compared with an existing common brake system, the embedded intelligent brake early warning system solves the problem that only the brake state is displayed and the brake degree cannot be indicated, and particularly, a rear vehicle can be informed at the first time when an emergency occurs, so that traffic accidents are avoided to the greatest extent. Meanwhile, a measuring method and a control method are optimized, and a safe, accurate and intelligent brake state early warning system is provided for automobiles.

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 most vehicles can only show the vehicle behind that the vehicle is in the braking state, and cannot display whether the vehicle is braking normally or in an emergency, so the driver of the vehicle behind cannot monitor the state of the vehicle ahead Accurate judgment. Especially when the vehicle is running at high speed, the front and rear speeds are relatively fast. When the car suddenly brakes in an emergency, the driver of the vehicle behind can only use the two information of the brake light of the front vehicle and the distance from the vehicle in front. It is judged whether emergency braking should be adopted, but it may be due to the relatively fast speed that the following vehicle has no time to take action or misjudgment, which may cause the vehicle t...

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
