ABSTRACT:
A wheel-speed detecting arrangement for detecting the wheel-speed of a vehicle having a fixed wheel-and-axle configuration includes a wheel generator connected to the wheel/axle configuration such that a first distance signal is produced indicating rotational displacement of the wheel. This first distance signal is then synchronized by use of a basic clock and passed onto a first counter which produces a first data signal indicative of the number of distance pulses. A second counter, enabled as a function of the output of the first counter, measures the number of clock pulses occurring within a measuring time period and generates a second data signal representing that time count. The first distance signal also operates a latch circuit such that, upon initial occurrence of any distance pulse, a reading of the second counter is taken and passed through to a calculating circuit. The calculating circuit uses this latched second data output and the first data signal to calculate the wheel-speed according to the relationship V=k . (n-1) t, where V is the wheel-speed, k is a proportionality constant, n is the first data signal, and t is the second data signal.
