Title
(DE) Drehwinkel-Erfassung mit 3-D-Sensor und Leiterplatten-paralleler Drehachse
Abstract
(DE)

Bei einer Sensoranordnung (8) zur Ermittlung eines Drehwinkels (WE) eines Magneten (6) um eine Drehachse (12), mit einem Sensor (18) zur Erfassung einer Radialkomponente (KR) und einer Tangentialkomponente (KT) des Messfeldes (16) des Magneten (6) und zur Ermittlung des Drehwinkels (WE) anhand einer atan-Funktion, ist der Sensor (18) mit Radialabstand (AR) zur Drehachse (12) auf einer zur Drehachse (12) parallelen Leiterplatte (20) montiert und gegenüber dem Magneten (6) um einen Axialabstand (AA) versetzt. Bei einem Entwurfsverfahren für die Sensoranordnung (8) wird ein anfänglicher Axialabstand (AA) und Radialabstand (RA) gewählt, der Verlauf (26) ermittelt, und Axialabstand (AA) und/oder der Radialabstand (RA) iterativ optimiert. In einer Wählhebelanordnung (2) für ein Fahrzeug, ist ein Wählhebel (4) mit dem Magneten (6) der Sensoranordnung (8) bewegungsgekoppelt. Bei einem Fertigungsverfahren für die Wählhebelanordnung (2) wird die Sensoranordnung (8) optimiert, mit der Wählhebelanordnung (2) verbaut, und eine Kompensationsanordnung (28) im Rahmen einer End-of-Line-Einstellung eingestellt. embedded image
