Patent ID: 8049608

Claim:
A system for determining a distance of travel of a brake cylinder piston, comprising: a brake cylinder having a brake cylinder piston; a pressure transducer operationally coupled to the brake cylinder and configured to determine a pressure measurement within the brake cylinder; and a control module of an electrically controlled pneumatic (ECP) brake control system operationally coupled to the pressure transducer and configured to convert the pressure measurement within the brake cylinder determined by the pressure transducer into at least one of a displacement time of the brake cylinder piston, an equalization pressure within the brake cylinder, a pressure build-up time within the brake cylinder, a pressure leakage from the brake cylinder, or any combination thereof, wherein the control module determines the distance of travel of the brake cylinder piston based on at least one of the displacement time of the brake cylinder piston, the equalization pressure within the brake cylinder, the pressure build-up time within the brake cylinder, the pressure leakage from the brake cylinder, or any combination thereof.
