Abstract

A magnetic signal transmitter (3) moves compared to first (4), second (14) and third (15) sensors and has a magnetic field. A signal, which is transmitted from the magnetic signal transmitter and varied with changes in a motor vehicle's wheel rotational status, is directed at the first sensor and detected by it.
