ABSTRACT:
A wheel lock control system is described for a wheel braking system in which the brake pressure producing the critical slip value and therefore the peak braking effort is precisely determined. The brake pressure that is reapplied following an incipient wheel lockup condition is determined as a function of (A) the brake pressure and wheel deceleration corresponding in time to the peak calculated tire torque tending to accelerate the wheel during braking prior to the detection of an incipient wheel lockup condition and (B) the brake pressure and wheel acceleration corresponding in time to the peak calculated tire torque tending to accelerate the wheel during wheel speed recovery following an incipient wheel lockup condition. By using these parameters, the precise brake pressure for establishing the critical wheel slip is determined so that the maximum braking effort may be established following a detected incipient lockup condition.
