Problems solved by technology

This type of system has the disadvantage that a steady flow must be provided when the ignition is off to be able to recognize the rotation of the steering wheel when the ignition is off
This leads to an undesired depletion of the vehicle battery when the vehicle has not been used for an extended period of time

Embodiment Construction

[0020] as available from Figures 1 to 6 As can be seen in , an embodiment of the sensor assembly 1 according to the invention for detecting an angle of rotation at a rotating member 10 in a vehicle comprises a measured value indicator 20 and at least one sensor 26 whose output signal Evaluated by the evaluation and control unit 30 . The rotating member 10 is coupled at its periphery with a measured value indicator 20 which, in combination with at least one sensor 26 , generates a signal representing the angle of rotation of the rotating member 10 and outputs this signal to an evaluation and control unit 30 . According to the invention, the measured value indicator 20 is embodied as a motion converter which converts the rotation 12 of the rotary member 10 into a translation 24 of the measured value indicator 20 , wherein the at least one sensor 26 is arranged at the measured value Next to the indicator 20 and monitor the entire translation area of ​​the measured value indica...

Abstract

The arrangement (1) has a movement transducer (20) that is coupled with a sensor (26) for generating signal representing signal indicating the angle of a rotation rotary component (10). The movement transducer is provided for converting the rotation (12) of rotary component into a translation (24) of the movement transducer. The sensor is arranged on the side of the transducer for monitoring the entire translational region of the transducer. The current position of the transducer in translation region which represents the rotation angle of rotary component, is determined by sensor.

Description

technical field [0001] The invention relates to a sensor assembly for detecting an angle of rotation at a rotating component in a vehicle according to the preamble of independent claim 1 . Background technique [0002] In known steering angle sensors, a counting wheel for determining the number of revolutions of the steering wheel is scanned contactlessly by means of a magnetic field sensor. This type of system has the disadvantage that a constant flow must be provided when the ignition is switched off in order to be able to recognize a rotation of the steering wheel when the ignition is switched off. This leads to an undesired drain of the vehicle battery when the vehicle has not been used for a long period of time. If this steady flow is not provided, the steering angle can no longer be determined unambiguously when the steering wheel is turned with the ignition switched off or the battery switched off. [0003] For example, laid-open document DE 10 2007 052 ​​162 A1 des...
