Abstract
A braking system for a vehicle includes devices that are configured to apply braking force to a wheel in response to a braking command. A first sensor is disposed to monitor a parameter associated with the braking force, and a spatial sensor is disposed to determine a linear range between the vehicle and a predefined locus point. A controller is operatively connected to the braking system and in communication with the first sensor and the spatial sensor. The controller detects a braking event and determines a time to stop and an applied braking force during the braking event, which is integrated over the time to stop. The braking system is evaluated based upon the total stopping distance and the integrated applied braking force during the braking event. A fault associated with the braking system is determined based upon the evaluation of the braking system.
