Problems solved by technology

[0002] With the rapid increase of the number of motor vehicles and the improvement of motor vehicle performance, especially the improvement of vehicle speed, there are more and more car rear-end collisions, which not only cause property losses, but also cause serious casualties
Rear-end collisions are mostly caused by the emergency braking of the vehicle in front, and the rear vehicle did not get the alarm signal in time, and the brakes were not timely.
Especially on the highway, it is easy to cause a series of rear-end collisions
This first point is because most of automobiles adopt a single brake signal at present, that is, it is the same during ordinary braking and emergency braking, so it cannot be noticed in time, and it cannot provide enough reminders to the driver, resulting in driving. The driver cannot judge the braking condition of the vehicle in front early and accurately, and cannot take timely measures to avoid hazards.
In order to solve this problem, in the prior art, for example, in the document ZL93229130.9, it is proposed to turn on the brake lights in advance through the collected release signal of the accelerator pedal before the brake pedal is touched, so as to increase the However, in this prior art, although the driver of the trailing vehicle has a longer time to judge, the warning signal he can obtain is still the normal brake light signal, therefore, the function It is not obvious; moreover, using the accelerator signal instead of the real brake signal to judge the braking situation may cause misjudgment, thus forming the illusion of "emergency braking" and causing unnecessary interference to trailing vehicles
In addition, in the prior art, for example in the document ZL200520097766.2, it is also suggested to install a separate single-chip microcomputer to monitor the vehicle speed change and send out an emergency braking signal accordingly. The emergency braking signal is sent by an additional LED matrix. The LED matrix Connected with a single-chip microcomputer; however, this solution also has defects and fails to meet actual needs, for example, the separately installed single-chip microcomputer and LED matrix are unsatisfactory in terms of cost and reliability; this solution cannot be adopted according to actual driving conditions Corresponding judgment conditions, thus, may cause misjudgment (wrong signal when there is no emergency braking) or judgment hysteresis (too late signal when there is emergency braking)
[0003] Therefore, the technical solutions in the prior art cannot meet the actual needs of traffic participants

Abstract

The invention relates to an emergency braking warning system, which is provided with a controller and an emergency braking warning lamp. The controller comprises an acquisition unit, a speed comparison unit, a time-keeping unit and a judgement unit; the acquisition unit acquires a braking signal and a speed signal, and the speed at the moment when the braking signal becomes effective is adopted as an initial speed value; the speed comparison unit acquires the initial speed value from the acquisition unit and compares the initial speed value with an emergency braking speed threshold; when the initial speed value is greater than the threshold, the time-keeping unit gives and provides emergency braking duration for the acquisition unit, and according to the emergency braking duration, the acquisition unit monitors the speed signal and adopts the speed reaching the emergency braking duration as a final speed value; the judgement unit acquires the initial speed value, the final speed valueand the emergency braking duration and determines an acceleration threshold in order to determine average acceleration and compare the average acceleration with the acceleration threshold to judge emergency braking; and the higher the initial speed value is, the shorter the emergency braking duration is and / or the lower the acceleration threshold is.

Description

technical field [0001] The invention relates to a motor vehicle safety system. Specifically, the present invention relates to an emergency brake warning system. Furthermore, it relates to a method for implementing an emergency brake warning of a motor vehicle by means of a control device and an emergency brake warning light. Background technique [0002] Along with the sharp increase of motor vehicle quantity and the raising of motor vehicle performance, especially the raising of speed, there are more and more car rear-end collisions, which not only cause property damage, but also cause casualties seriously. Most of the rear-end collisions are due to the emergency braking of the vehicle in front, the rear vehicle does not get the alarm signal in time, and the brakes are not timely. Especially on the highway, it is easy to cause a series of rear-end collisions. This first point is because most of automobiles adopt a single brake signal at present, that is, it is the same d...
