ABSTRACT:
An apparatus for generating a reference signal in a brake control system stores a reference signal representative of a reference braking condition and compares this reference signal with a conditioned wheel signal. Depending on the outcome of the comparison, the reference signal is either updated to correspond to a reduced reference braking condition or ramped to correspond to an increased braking condition. The reference signal is not simultaneously ramped and updated, and is, therefore, precisely controlled. In a first embodiment, the amount by which the reference signal is ramped is a function of the past history of the reference signal: each time the reference signal is ramped the ramp rate is increased and each time the reference signal is updated the ramp rate is decreased. The apparatus of this embodiment generates the conditioned wheel signal from the wheel signal by averaging the maximum and minimum wheel signals in a preselected group and by then reducing this average by an amount proportional to the difference between the maximum and minimum wheel signals. In this way undesirable oscillations, such as those due to pitching of the wheel truck, are filtered out. In a second embodiment the conditioned wheel signal is set equal to the minimum wheel signal in a preselected group, and the reference signal is set equal to the conditioned wheel signal in the event the reference signal is less than the conditioned wheel signal.
