Embodiment Construction

[0039] figure 1 A first circuit diagram of the sensor device 1 is shown. The sensor device 1 includes a voltage source 2 of the motor vehicle, which also supplies an operating voltage 3 when the ignition is switched off. The sensor device 1 has a multi-turn sensor 4 which is suitable for detecting the number of revolutions of a permanent magnet 5; wherein the actuator is connected to a first circuit 6 which is only supplied with work when the ignition is switched on Voltage 3 (e.g. connected to terminal 15), wherein the multi-turn sensor 4 is connected to a second circuit 7 (i.e. terminal 30) which is supplied with an operating voltage 3 (volts) even when the ignition is switched off .

[0040] The arrangement of the multiturn sensor 4 in the second circuit 7 at the second terminal 30 enables the multiturn sensor 4 to permanently sense the movement of the permanent magnet 5 on the one hand and to store the movement of the permanent magnet 5 on the other hand. 4 The numerica...

Abstract

The invention relates to a sensor arrangement for determining a position of an actuator in a motor vehicle, wherein the sensor arrangement comprises a voltage source of the motor vehicle, which also provides an electrical operating voltage when the ignition is deactivated; wherein the sensor arrangement has at least one multi-turn sensor, which is suitable for detecting a number of revolutions ofa permanent magnet; wherein the actuator is connected to a first circuit, which is only supplied with an operating voltage when the ignition is activated, wherein the multi-turn sensor is connected toa second circuit, which is also supplied with an electrical operating voltage when the ignition is deactivated.

Description

technical field [0001] The invention relates to a sensor device for determining the position of an actuator (or an operating unit of the actuator) in a motor vehicle and to a method for operating the sensor device. In particular, the sensor device is provided for determining the position of the clutch actuator. The clutch actuator is provided in particular for actuating a clutch of a motor vehicle, for example a friction clutch. In particular, the actuator has a slip-free transmission, ie for example includes a screw drive. Background technique [0002] The position of the actuator can be determined as a function of the number of revolutions of a permanent magnet arranged on the screw drive, for example by means of a multiturn sensor. A more precise determination of the position of the actuator is possible via an additional rotor position sensor. The rotor position sensor determines the angular position of the permanent magnet within one revolution of the permanent magnet...
