Active magnetic field sensor, has periodic signals provided at sensor outputs processed via 2 or more separate channels of electronic signal evaluation circuit

摘要

The magnetic field sensor has at least one magnetic sensor element for converting a temporally periodic magnetic field into a temporally periodic electrical signal, supplied to an electronic signal evaluation circuit, in which the periodic signals (38,39) at the magnetic field sensor outputs are actively processed via 2 or more separate signal channels. Independent claims are included for the following: (a) a sensor device using a magnetic field sensor; (b) a wheel position sensor; (c) an automobile control device.
