Description
Technical field
The present invention relates to motor vehicle brake technical field, more particularly to a kind of brake pad wear alarm set and method.
Background technology
With the development of society, automobile is increasingly popularized, while being brought convenience to people's life, traffic thing is also increased
Therefore probability of happening.In the case of all contingency causing deaths, death toll accounts for first place caused by traffic accident.The whole world at present
There are 1,270,000 people to be killed in an automobile accident every year, wherein a big chunk reason is due to that brake system of car failure causes.
The service brake principle of vehicle is that brake block utilizes brake pad and brake disc（Drum）Rub, by the portion of vehicle
Transfer can be converted into heat energy, thus play the purpose of braking, therefore in the brakes of automobile, brake block is the most key
Breaking piece, directly determine braking effect quality.To meet to brake needs, brake block friction material in design has foot
Enough thickness, but as the use of automobile, friction material can gradually wear out, are thinning, after brake pad wears to a certain extent, still
It can be continuing with, but braking ability will substantially reduce, it is easy to trigger security incident because braking effect is bad, it is at this moment necessary
The brake block more renewed, just can guarantee that traffic safety.And present case is, the rate of depreciation of brake-pad friction block is by making material
Expect, drive to be accustomed to, brake the influence of many factors such as frequency of use, rate of depreciation differs, and driver can not understand and clearly brake
The abrasion condition of piece and replacement cycle, cause brake block heavy wear but still be continuing with, this is to cause braking system in driving
Failure of uniting triggers the main reason for security incident.
Some luxury cars can be furnished with shoe brake warning function at present, but can just be reported when brake block may wear to the limit
Alert, as before stated, now the braking of brake block seriously reduces, it cannot be guaranteed that the safety of driving.It is currently the only
The method that can guarantee that discovery situation in time is exactly periodically to go 4S shops or vehicle repairing factory to check the brake block of automobile, but will certainly give car owner
Bring certain trouble.If a kind of auto parts machinery that can monitor brake block abrasion condition, traffic safety is greatly improved
Property, reduce traffic accident incidence.
The content of the invention

In closure state, when the brake pedal resets, the controlling switch is off, and the logging modle records the big of the external force
It is small, from effect is started until the initial velocity and end speed under the forced deceleration of the brake block of time interval and an automobile of disappearance
Degree；
One processing module, is electrically connected with the detecting module and the logging modle, the size of the external force, time interval and just
Speed and end speed input the processing module, and according to above-mentioned numerical value, the processing module calculates the external force in the time interval
Caused kinetic energy；
One judge module, the processing module is electrically connected with, the judge module adds up external force production in some time intervals
Raw kinetic energy sum, when close to a setting value, the judge module sends an alarm signal；
One alarm module, the judge module is electrically connected with, when the alarm signal inputs the alarm module, alarm module hair
Go out information warning.
The present invention also provides a kind of brake pad wear based reminding method, and this method includes：
When trampling a brake pedal, detecting module measurement acts on the size of the external force of a brake block and output, control
Switch is triggered, and in closure state, when the brake pedal resets, the controlling switch is off；
Logging modle record the external force size, from start effect until disappearance time interval and an automobile in the brake
Initial velocity and end speed under the forced deceleration of car piece；
Processing module is calculated in the time interval according to the size of the external force, time interval and initial velocity and end speed
Kinetic energy caused by the external force；
Judge module adds up kinetic energy sum caused by the external force in some time intervals, when close to a setting value, sentences
Disconnected module sends an alarm signal；
The alarm signal inputs alarm module, and the alarm module sends information warning.
Especially, the energy discharged when the setting value reaches the limit of wear by a brake block.
Especially, the information warning is that a warning lamp or a word are reminded.
Compared to prior art, brake pad wear alarm set of the invention and method, the abrasion of brake block is monitored in real time
Situation, prompting is sent when reaching the limit of wear, convenient use person changes in time, ensures traffic safety.
【Brief description of the drawings】
Fig. 1 is the frame diagram of present invention brake pad wear alarm set；
Fig. 2 is the flow chart of present invention brake pad wear based reminding method.
