A method of controlling a braking force applied to at least one wheel supporting a tire that includes steps of issuing a braking command (), commanding an amount of tire stretch based on the braking command (), estimating an amount of tire stretch for the tire based at least in part on wheel speed (), and controlling the braking force applied to the wheel so that the estimated amount of tire stretch approaches the commanded amount of tire stretch (). Also, a system () for controlling braking based on a determination of tire stretch that includes a tire stretch command generator () generating a tire stretch command based on a braking command, a reference velocity estimator () producing a first signal indicative of a velocity, a tire stretch estimator () producing a second signal indicative of an amount of tire stretch, and a brake force command generator () generating a brake force command based on the braking command, the first signal and the second signal.

Method and system using tire stretch data to control braking

Methods and apparatus to control electro-mechanical brakes are disclosed. A disclosed example method of controlling a brake actuator comprises receiving a value representative of a velocity of a piston associated with the brake actuator relative to a pressure plate mounted on a wheel, and determining a control input for the brake actuator based on the velocity value.
