Detailed description of the invention
It is more fully described the exemplary embodiment of the present invention below with reference to accompanying drawings.Although accompanying drawing showing the exemplary embodiment of the present invention, it being understood, however, that may be realized in various forms the present invention and should not limited by embodiments set forth here.On the contrary, it is provided that these embodiments are able to be best understood from the present invention, and complete for the scope of the present invention can be conveyed to those skilled in the art.
The invention provides a kind of brake block abrasion condition alarm method, the method includes: by the distance between induction apparatus detection brake block and brake disc, obtains measuring distance；According to the measurement distance obtained, analyze and obtain the brake block degree of wear；According to the brake block degree of wear, send alarm signal.Wherein, induction apparatus is the induction apparatus that can be used for measuring distance, and such as, induction apparatus can be infrared distance-sensor etc..Below by specific embodiment, the method is illustrated.
Fig. 1 a shows the flow chart of the brake block abrasion condition alarm method embodiment one that the present invention provides.As shown in Figure 1a, the method for the present embodiment specifically includes following steps:
Step S101, by the induction apparatus that is arranged on brake block detection distance between brake block and brake disc under braking state, obtains the first measurement distance.
Wherein, induction apparatus can be arranged at the inside of brake block.Induction apparatus specifically can be fixed by those skilled in the art according to practical situation, does not limits.Such as, induction apparatus can be fixed on inside brake block by screw, grab etc..Specifically, as shown in Figure 1 b, the centre position of brake block 120 is provided with a through hole, induction apparatus 140 is arranged in this through hole, so that induction apparatus 140 is embedded in the inside of brake block 120, induction apparatus 140 may be installed on installation carrier 130, wherein, installing carrier 130 can be printed circuit board (PCB) etc..Shown in Fig. 1 b for the situation under non-braking state, brake block 120 separates with brake disc 110, under at braking state, brake block 120 will fit tightly with brake disc 110, and induction apparatus 140 is arranged at the inside of brake block 120, therefore, in step S101, detect under braking state the distance between brake block 120 and brake disc 110 by induction apparatus 140, obtain the first measurement distance.Measure distance by first and can reflect the thickness of brake block 120.
Step S102, it is judged that whether first measure distance less than the first preset value；The most then perform step S103；If it is not, then perform step S101.
Wherein, the first preset value is more than the second preset value.First preset value and the second preset value can specifically be arranged by those skilled in the art according to actual needs.Generally, the thickness of brand-new brake block is about 1.5cm, and along with constantly rubbing in using, the thickness of brake block can be the most thinning.When the thickness of brake block is about 5mm, user then needs to change brake block, to avoid the occurrence of traffic safety hidden danger.Therefore, the first preset value can be set to 8mm, and the second preset value can be set to 5mm.If the first measurement distance is less than 8mm, then perform step S103；If the first measurement distance is more than or equal to 8mm, then perform step S101, continue through the induction apparatus detection being arranged on brake block distance under braking state between brake block and brake disc.
Step S103, it is judged that whether first measure distance less than the second preset value；The most then perform step S106；If it is not, then perform step S104.
Through step S102 judge to obtain the first measurement distance less than the first preset value in the case of, in step s 103, also need to judge that whether the first measurement distance is less than the second preset value.If obtaining the first measurement distance less than the second preset value through judging, then perform step S106；If obtaining the first measurement distance more than or equal to the second preset value through judging, then perform step S104.
Step S104, determines that the brake block degree of wear is first degree of wear.
When judging to obtain the first measurement distance more than or equal to the second preset value through step S103, it is determined that the brake block degree of wear is first degree of wear.
Step S105, sends the first alarm signal, in order to inform user's brake block abrasion condition.
When step S104 determines after the brake block degree of wear is first degree of wear, in step S105, send the first alarm signal, inform user's brake block abrasion condition by the first alarm signal.Such as, may inform the user that brake block abrasion condition is more serious by the first alarm signal, it is simple to user understands brake block abrasion condition, change the preparation of brake block to remind user to carry out.Specifically, can be provided for showing the display module of the brake block degree of wear on the display floater of automobile, when determining the brake block degree of wear and being first degree of wear, send the first alarm signal, the display module being used in the display brake block degree of wear by the first alarm signal is shown as the first particular color, such as green, in order to inform that user's brake block abrasion condition is more serious.
Step S106, determines that the brake block degree of wear is second degree of wear.
When judging to obtain the first measurement distance less than the second preset value through step S103, it is determined that the brake block degree of wear is second degree of wear.When the brake block degree of wear is second degree of wear, then it represents that the abrasion condition of brake block is more serious than the abrasion condition of first degree of wear.
Step S107, sends the second alarm signal, in order to point out user to change brake block.
When step S106 determines after the brake block degree of wear is second degree of wear, in step s 107, send the second alarm signal, change brake block by the second warning signal prompt user.Such as, change brake block in time by the second warning signal prompt user, to avoid, because the thickness of brake block crosses thin, traffic safety hidden danger occurs.Specifically, when determining the brake block degree of wear and being second degree of wear, send the second alarm signal, made by the second alarm signal in the display floater of automobile for showing that the display module of the brake block degree of wear is shown as the second particular color, such as red, to inform that user's brake block abrasion condition is extremely serious, need to change in time.User is by checking the color shown by the display module for showing the brake block degree of wear, so that it may know brake block abrasion condition easily.
The brake block abrasion condition alarm method provided according to the present embodiment, by the induction apparatus that is arranged on brake block detection distance between brake block and brake disc under braking state, obtain the first measurement distance, then measure distance to first to judge, when judge obtain the first measurement distance less than the first preset value and more than or equal to the second preset value time, determine that the brake block degree of wear is first degree of wear, send the first alarm signal, in order to inform user's brake block abrasion condition；When judging to obtain the first measurement distance less than the second preset value, determine that the brake block degree of wear is second degree of wear, send the second alarm signal, in order to point out user to change brake block.The technical scheme provided according to the present invention, user, without checking brake block, can know brake block abrasion condition easily, in order to is replaced brake block in time, improve the convenience obtaining brake block abrasion condition, it is to avoid because the thickness of brake block crosses thin, traffic safety hidden danger occurs.
