Patent ID: 7744167

Claim:
An adaptive brake application and initial skid detection system for a vehicle braking system supplying brake pressure for braking of a wheel of a vehicle, comprising: a wheel brake configured to receive the brake pressure and apply brake torque to the wheel; a brake pressure sensor configured to measure the brake pressure and to generate a brake pressure signal that is a function of the brake pressure; a wheel velocity sensor configured to produce a wheel velocity signal that is a function of the rotational speed of the wheel; a wheel velocity comparator configured to compare said wheel velocity signal with a reference velocity signal and to generate a wheel velocity error signal that is indicative of a difference between said wheel velocity signal and said reference velocity signal; a pressure bias modulator integrator configured receive the wheel velocity error signal and to provide an anti-skid control signal responsive to the wheel velocity error signal; and an initializing unit configured to provide a predetermined constant brake pressure value plus a predetermined constant increment of brake pressure to the pressure bias modulator integrator at a time when said brake pressure is equal to said predetermined constant brake pressure, said initializing unit connected to receive the brake pressure signal, and said initializing unit configured to provide the brake pressure signal to the pressure bias modulator integrator at a time when the wheel velocity error signal is greater than a predetermined wheel velocity error threshold.
