the identification code reader 30 is used for scanning the identification code 20 and then reading the identification code information, the output end of the identification code reader 30 is in communication connection with the OBD interface 40 of the vehicle, and the identification code reader 30 sends the read identification code information to the vehicle-mounted bus after passing through the OBD interface 40 and the vehicle-mounted gateway 90; the vehicle-mounted controller 50 reads the identification code information from the vehicle-mounted bus; the vehicle-end controller 50 is in communication connection with the server, and the vehicle-end controller 50 receives the corresponding relationship from the server; the vehicle-end controller 50 determines the information of the brake lining 10 to be replaced according to the identification code information and the correspondence relationship, and sends the information of the brake lining to be replaced to the part information management system 60. The parts information management system 60 can be activated to delete the information of the original brake lining as the brake lining information with the information of the new brake lining to be replaced. The brake lining information may include information such as the type of the lining, the friction coefficient, and wear characteristic information. All the schemes can be realized through an automatic means without manual intervention, so that the operation process is simplified and the efficiency is improved. And because the information is input in an automatic scanning mode, the condition of misreading can not occur, and the accuracy of information input is improved.
Preferably, the identification code 20 in the above solution is detachably provided on the surface of the brake lining 10 to be replaced. The identification code 20 can be detached and can also be installed in a vehicle together with the brake lining, for example, the identification code can be detached after scanning is finished, and the subsequent influence on the normal use of the brake lining can be avoided. Preferably, the identification code 20 is adhered to the surface of the brake lining 10 to be replaced by an adhesive layer. The identification code 20 may be in the form of a two-dimensional code, a bar code, or the like.
Preferably, as shown in fig. 2, the brake lining 10 to be replaced is used as a brake lining 101 after being installed in an automobile and is worn during use, wherein a wear sensor 102 is further included and is arranged on one side of the brake lining 101, the wear sensor 102 has the same wear degree as the brake lining 101, and the wear sensor 102 detects the wear degree of the wear sensor 102; and the vehicle end controller 50 receives the wear degree of the wear sensor itself sent by the wear sensor 102 as the wear degree of the brake lining. As shown in fig. 3, the wear sensor 102 includes a plurality of resistive patches 104 connected in parallel, as well as a power supply 105 and a sensor control unit 103; two ends of each resistance sheet 104 are respectively and electrically connected with the positive electrode and the negative electrode of a power supply 105; the sensor control unit 103 detects the current value of the circuit in which the plurality of resistive patches 104 are located, and obtains the degree of wear of the wear sensor 102 from the relationship between the current value of the circuit in which the plurality of resistive patches 104 are located and the degree of wear of the wear sensor 102. Obviously, according to ohm's law, the resistance value of the loop in which the plurality of resistance cards 104 are located can be determined according to the power supply voltage and the measured current, and as the wear degree of the wear sensor is different, the number of the wear resistance cards 104 is different, which results in different resistance values of the resistance cards 104 connected in parallel, so that after the loop resistance value is determined, the wear degree of the wear sensor can be determined. In the above scheme, the resistance values of the different resistive patches 104 may be the same or different, and for the sake of simplifying the calculation, it is preferable that the plurality of resistive patches 104 in the wear sensor have the same resistance value.
The sensor control unit 103 can be realized by selecting a chip with a function of measuring a current value, or selecting a current sensor to be independently arranged, the current sensor sends a detected current value to the sensor control unit, and the sensor control unit 103 can obtain a calculated loop resistance according to a calculation model of ohm's law, so that the degree of wear is obtained.
As shown in the drawing, the wear sensor 102 has the same degree of wear as the brake lining 101, and therefore, the degree of wear of the brake lining 101 can be replaced by the degree of wear of the wear sensor 102. On the basis, the wear sensor 102 sends the wear degree of the wear sensor to the vehicle-end controller 50, so that the vehicle-end controller 50 can obtain the wear degree of the brake lining 101 in real time, and the active safety of the vehicle is greatly improved.

The data in the sensor controller unit 103 can be safely verified through the vehicle gateway 90, and it is ensured that the data entering the vehicle-end controller 50 are all safe and effective data.
In the above aspect, in order to ensure the detection accuracy of the wear sensor 102, the wear sensor 102 further includes an insulating housing adapted to be connected to one side of the brake lining 101, and the housing encloses the plurality of resistive sheets 104, the power supply 105, and the sensor control unit 103 inside thereof.
