Title:
ACTIVE MAGNETIC SENSOR FOR ELECTRONIC BRAKING SYSTEMS
Document Type and Number:
WIPO Patent Application WO2002042133
Kind Code:
A9
Abstract:
The invention relates to an active magnetic sensor, in particular for detecting the rotational behaviour of a wheel. Said sensor comprises a magnetoelectric transducer (2), which is electrically connected to a modulator (5), a current-source sub-assembly (4), which controls the signal current produced at the sensor output (k3, k4) and is characterised by an undervoltage monitoring circuit (10), connected to the sensor output (k3, k4). Said circuit monitors the electric signal at the sensor output (k3, k4) for the undercutting of a first predetermined threshold current (VU) and based on the result of said monitoring, controls the signal current produced at the sensor output (k3, k4), by influencing the current-source sub-assembly (4).
