Abstract
A spin-up detection apparatus for a brake control system operates to monitor a wheel speed signal indicative of the rotational velocity of a wheel until the wheel speed signal exceeds an absolute velocity threshold. Once this threshold is exceeded, the apparatus then monitors the rate of change of the wheel speed signal. When this rate of change falls below a predetermined level, a control signal is generated to indicate that wheel spin-up is substantially complete.
