Abstract
A brake system and a method of control. The brake system comprises a friction brake, a sensor unit, and a controller. The sensor unit is disposed on a brake pad assembly of the friction brake and comprises a first sensor and a second sensor that is electrically connected to the first sensor.
Claims20
A brake system comprising:
- a friction brake that comprises a brake pad assembly, the brake pad assembly comprising:
- a backplate that comprises a first side and a second side disposed opposite the second side;
- and
- friction material that extends from the first side and extends away from the second side;
- a sensor unit that is disposed on the brake pad assembly, the sensor unit comprising:
- a first body that extends from the first side of the backplate and is disposed proximate the friction material;
- a first sensor that is disposed inside the first body;
- a second body that extends from the second side of the backplate and is connected to the first body;
- and
- a second sensor that is disposed inside the second body and that is electrically connected to the first sensor;
- and
- a controller that is electrically connected to the second sensor by a data bus.

A method of controlling a brake system, the method comprising:
- providing a signal with a thermistor of a sensor unit to a second sensor of the sensor unit, the sensor unit being disposed on a brake pad assembly of a friction brake, wherein the signal is indicative of a temperature of the brake pad assembly;
- generating, with the second sensor, an output signal that comprises a serial number of the second sensor and a temperature code based on the signal from the thermistor;
- communicating the output signal to a controller;
- and
- identifying, with the controller, a location of the sensor unit based on the serial number;
- identifying, with the controller, a temperature of the sensor unit based on the temperature code;
- and
- communicating, with the controller, the location and temperature of the sensor unit to a communication device.
