Abstract
An improved modulator for an anti-skid brake control system generates a modulated brake control signal as a time integral function of the difference between an input signal indicative of a braking condition and a variable threshold signal. The preferred embodiment includes a computer which stores a number of threshold signals. An appropriate one of these threshold signals is selected depending on the magnitude of the velocity of the braked wheel. Furthermore, the modulator adjusts the value of the modulated brake control signal in response to skids more severe than a preset level in a manner that varies in response to the frequency of such more severe skids.
