BRAKE PAD WEAR SENSOR WITH WIRELESS DATA TRANSMISSION

A vehicle wheel monitoring device includes a tire pressure monitoring unit, a tire pressure sensor unit disposed at a wheel of the vehicle and a brake pad wear sensor unit disposed at a wheel of the vehicle. The brake pad wear sensor unit includes a brake pad wear sensor and a wireless transmitter configured to receive the signal emitted from the brake pad wear sensor and wirelessly transmit it tothe tire pressure monitoring unit. An energy harvesting device is configured to convert energy derived from an external source into electrical power, and to provide the electrical power to the brakepad wear sensor unit and the transmitter. The brake pad wear sensor unit and the tire pressure sensor unit are monitored by the tire pressure monitoring unit. 一种车辆车轮监测装置包括轮胎压力监测单元、被设置在车辆的车轮处的轮胎压力传感器单元以及被设置在车辆的车轮处的制动衬块磨损传感器单元。制动衬块磨损传感器单元包括制动衬块磨损传感器和无线传输器，无线传输器被配置为接收从制动衬块磨损传感器发出的信号并且将该信号无线地传输到轮胎压力监测单元。能量采集装置被配置为将来自外部源的能量转换成电能，并且将电能提供给制动衬块磨损传感器单元和传输器。制动衬块磨损传感器单元和轮胎压力传感器单元由轮胎压力监测单元监测。
