Abstract
A brake monitoring system and method for a vehicle having multiple axles and a plurality of brake actuators and an engine control module, each brake actuator being associated with one of the axle. The system include sensors for measuring, in real-time, brake pressure and brake lining wear, and generating first and second signals. The first and second signals are received and stored in a chassis communications module. The chassis communications module detects fault condition of the brakes as a function of the first and/or second signals and for recording the fault condition, the fault condition being one of a brake monitor warning and a brake lining warning and provides an indication of status via warning lights.

23. A brake monitoring system for a vehicle having an engine control module, comprising:
-
a brake actuator for actuating a brake pad; an actuator sensor for monitoring the stroke of the brake actuator and generating a stroke signal indicative of a condition of the brake actuator; a brake pad wear sensor for detecting pad wear and generating a wear signal indicative of the pad wear; a controller interactive with said actuator sensor for receiving the stroke signals and said brake pad wear sensor for receiving the wear signal, said controller evaluating the signals for determining a fault condition in the brake actuator and the brake pad and generating a warning signal corresponding to the fault condition; and said controller signaling the engine control module to adjust engine speed in response to the fault condition determined by the controller. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method of monitoring a brake system of motor vehicle having brake actuators for actuating brake pads, comprising the steps of:
-
monitoring individual movement of each brake actuator and generating an actuator signal indicative of a condition said brake actuator; monitoring wear of each brake pad and generating a wear signal indicative of the condition of the brake pad; monitoring pressure applied to said brake actuator and generating a pressure signal indicative of the pressure applied to said brake actuator; determining a fault condition in said brake system by evaluating the an actuator signal the wear signal, and the pressure signal; and generating an engine control signal in response to the fault condition and modifying operation of the motor vehicle corresponding to the fault condition by transmitting an engine control signal to an engine control module of the motor vehicle based upon said fault condition. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42)
