Patent ID: 7996136

Claim:
A method for monitoring brake performance in a vehicle having at least four wheels, at least two axles, and an ABS electronic control unit, the method comprising the steps of: utilizing a program expansion of said ABS electronic control unit configured to determine at least one of sums and differences of braking distances of each wheel of said wheels having a wheel speed sensor, wherein said at least one of sums and differences of braking distances is determined only when said vehicle is braking in at least one preselected vehicle braking operation including predefined brake actuations with brake forces between a minimum and a maximum brake force; comparing said at least one of sums and differences of braking distances of each wheel of said wheels having a wheel speed sensor with one another over a predefined travel distance; and recognizing at least one wheel of said wheels having a braking distance of above-average length as being inadequately braked.
