Title: Wheel speed detecting method
Inventor: IMANAKA ASAJI
IPC: G01P3/489
Filed: 1985-04-23
Abstract: PURPOSE:To reduce an error caused by the omission of fractions of a pulse of the last distance and the difference of measured values of a necessary time at high and low speeds by deriving a wheel speed by a specified expression. CONSTITUTION:A clear signal is outputted from a clear signal generator CS by which a distance pulse counter DC is cleared and a pulse counting value becomes '0', also a time counter TC is also cleared and its clock counting value also becomes '0'. In this case, an FF circuit is reset and a gate circuit GA is closed and no reference clock is inputted to a counter TC. Also a latching circuit LA continues the previous latching state since no latching signal is inputted. In this state, when a distance pulse after synchronization is inputted to the counter DC, this pulse is counted successively, the FF circuit is set to its first one and the circuit LA is also operated. In this state, a wheel speed (v) is derived by the equation. In this regard, the number of pulses, the time required by the time when the last distance pulse is inputted and a proportional constant are denoted as (n), (t), and (k) respectively.
