ABSTRACT:
In an anti-skid brake control system, wheel acceleration or deceleration is calculated at a different timing than the calculation of the wheel speed and a control signal. The intervals between calculations of wheel acceleration and deceleration will often be longer than those of the control signal. Wheel acceleration and deceleration values in the intervals between calculations are extrapolated on the basis of the rate of change derived from the difference between two successively derived wheel acceleration and deceleration values and elapsed time since the last derivation. The extrapolating value is used as a replacement for the most recently derived wheel acceleration in deriving the control signal.
