Abstract: The invention provides a method for controlling a vehicle with a braking system including a modulator pump. A first fluid line can communicate brake fluid from the master cylinder to a brake caliper. An isolation valve including a pressure bypass can be disposed along the fluid line between the master cylinder and the brake caliper. A second fluid line can extend from a first position along the first fluid line between the master cylinder and the isolation valve to a second position along the first fluid line between the isolation valve and the brake caliper. A modulating pump is disposed along the second fluid line to pump fluid to the brake caliper during a controlled brake event. The modulator pump is engaged to pump fluid to the brake caliper until the pressure in the first fluid line reached slightly below the predetermined pressure to prevent the isolation valve from opening in response to excessive pressure.

Abstract: The present invention provides a method, a computer usable medium including a program, and a system for monitoring inflation in a plurality of vehicle tires. The method and computer usable medium include the steps of determining a direct pressure in at least one primary tire and determining a rolling radius for the primary tire and at least one secondary tire. A pressure difference is determined based on the determined rolling radius for the primary and secondary tires. The determined pressure difference is adjusted based on the determined direct pressure of the primary tire. The determined pressure difference is compared to at least one threshold value. The system includes means for achieving the method steps of the invention.

Abstract: A method for determining the axle load on a rotating tire or the percentage axle load of a first axle of a moving vehicle. The relationship between the axle load on a test tire and the rolling radius of the test tire under a constant pressure is empirically determined, and optionally the relationship between the pressure of the test tire and the rolling radius of the test tire at a constant axle load is empirically determined. A measurement of the rotational speed of the rotating tire is taken, and optionally a measurement of the pressure of the rotating tire is taken using a pressure sensor. The axle load or percentage axle load is determined from the measurement (or optionally from the measurements) and from the relationship (or optionally from the relationships).
