| Condition monitoring and fault diagnosis of the brake is an important part of the driving safety. Research on real-time monitoring of the brake linings or pads is less reported than material and manufacture of the brake linings or pads. With development of modern micro-fabrication and electronic technology, integrated and micro-sensors have appeared, which are strongly tools of real-time monitoring. Systematic monitoring for the brake linings or pads is based on that sensor. Sensor array technology solves a difficult problem that is how to measure unbalanced abrasion information of the brake linings or pads in complicated conditions. It improves reliability and stability of the system in course of measuring information. Systematic functional realization is based on it. Multisensor information fusion deals with measuring data in the system. It improves data precision and sustains systematic working order. Design of alterable resistance sensor solves a difficult problem in course of measuring thickness information of the brake linings or pads. It is the precondition which system carries out through. Many anti-jamming designs in software and hardware, and software structural design assure system safety, reliability and maintainability.
