Embodiment Construction

[0034] as from Figures 1 to 11 As can be seen, the shown exemplary embodiments of the sensor arrangement 1 , 1A, 1B, 1C, 1D according to the invention for detecting the angle of rotation α at the rotating component 10 in a vehicle each have a predetermined A first measured value indicator 20 , 20A, 20B, 20C, 20D coupled to the rotating member 10 in a first speed ratio and a second measured value indicator coupled to the rotating member 10 in a predetermined second speed ratio on the circumferential side 40, 40A, 40B, 40C, 40D. Here, measured value indicators 20 , 20A, 20B, 20C, 20D, 40 , 40A, 40B, 40C, 40D are connected to at least one measured value receiver 30 , 30A, 30B, 30C, 30D, 30E, 50 , 50A, 50B, 50E are connected to generate at least one piece of information for acquiring the current rotation angle α of the rotating member 10 . According to the invention, the two measured value indicators 20 , 20A, 20B, 20C, 20D, 40 , 40A, 40B, 40C, 40D are mounted on a common axis ...

Abstract

A sensor arrangement for sensing a rotation angle on a rotating component in a vehicle includes a first measurement transmitter. The first measurement transmitter is coupled at a periphery with a predefined first transmission ratio to the rotating component. The sensor arrangement includes a second measurement transmitter coupled at the periphery with a predefined second transmission ratio to the rotating component. The first and second measurement transmitters are mounted on a common axis of rotation. The first and second measurement transmitters generate, in conjunction with a corresponding first and second to measurement recorder, data configured to determine the current rotation angle of the rotating component.

Description

technical field [0001] The invention relates to a sensor arrangement for detecting a rotational angle at a rotating component in a vehicle of the type according to independent claim 1 . Background technique [0002] In known steering angle sensors, a counter wheel for determining the number of revolutions of the steering wheel is detected contactlessly by means of a magnetic field sensor. A disadvantage of such a system is that, with the ignition switched off, a static current must be supplied in order to be able to detect a rotation of the steering wheel with the ignition switched off. This leads to unnecessary discharge of the vehicle battery in vehicles that have not been used for a long period of time. If this static current is not supplied, it is no longer possible to unambiguously determine the steering angle when the steering wheel is turned with the ignition switched off or the battery switched off. [0003] The development provides a new steering wheel angle measu...
