Determining wheel revolution rate or speed or speed of travel of a motor vehicle involves computing speed of travel signal based on mean time interval between successive transducer pulses

摘要

The method involves detecting a pulse sequence signal proportional to the vehicle speed from a speed of travel sensor (1), determining the intervals between successive pulses of the pulse sequence signal, averaging the intervals to produce an averaged interval between successive pulses and computing the speed of travel signal on the basis of the mean interval..
