ABSTRACT:
A wheel speed sensing system for a brake control system is characterized in that the periodic signal generated by a wheel speed transducer is used to trigger a series of digital signals having a frequency proportional to that of the periodic transducer signal. Clock signals are counted between a selected pair of digital signals to provide a digital measure of the time interval separating the digital signals and hence the period of the periodic signal. In a preferred embodiment the number of intervening digital signals separating the selected pair of digital signals is automatically chosen to maintain the time resolution of the measurement above a preselected value.
