Method for differentiating between right and left wheels of car, involves producing centrifugal acceleration signal for determination of sign, and determining sign as sign of changes of portion of centrifugal acceleration signal

摘要

The method involves producing a tangential acceleration signal by measuring tangential acceleration. A centrifugal acceleration signal is produced for determination of a sign by measuring centrifugal acceleration, where the centrifugal acceleration signal contains a portion periodically changed in accordance with rotational frequency of a wheel (1) and another portion proportional to the rotational frequency of the wheel. The sign is determined as a sign of changes of the latter portion of the centrifugal acceleration signal.
