The invention relates to a method for ascertaining a rotational angle (E) of a shaft (). In order to increase the accuracy of the ascertainment within a greater predefined angle range in relation to the prior art, the following steps are provided:

Ascertaining a rotational angle of a steering shaft by means of three toothed gears

The invention relates to a sensor system (), and a method for determining an absolute rotation angle (&#x3b4;) of a shaft () with a rotation angle range of more than one revolution and to a vehicle fitted with a sensor system (), wherein the sensor system () has a main rotor () that can be connected rotationally synchronously to the shaft (), a first auxiliary rotor () which is mechanically coupled to the main rotor (), a second auxiliary rotor () mechanically coupled to the main rotor (), a first sensor device (SE) which is assigned to the first auxiliary rotor () for generating a first sensor signal dependent on a rotation angle of the first auxiliary rotor (), a second sensor device (SE) which is assigned to the second auxiliary rotor () for generating a second sensor signal dependent on a rotation angle of the second auxiliary rotor (), a third sensor device (SE) which is assigned to the main rotor () and which is used for generating a third sensor signal dependent on a relative rotation angle (&#x3b3;) of the main rotor () and an evaluation device for determining the absolute rotation angle (&#x3b4;) of the main rotor () from the sensor signals of the sensor devices (SE, SE, SE). The detection range (&#x3b1;) of the third sensor device is less than 360&#xb0;.

Sensor system for determining an absolute rotational angle of a shaft, method for determining an absolute rotational angle of a shaft, and vehicle having a sensor system

The invention relates to a sensor device for a vehicle for capacitively detecting input means in the region of a detection area, having a first sensor electrode and a second sensor electrode and an evaluation unit which is electrically connected to a respective first connection of the first sensor electrode and of the second sensor electrode via connection lines. The object of the invention is to provide a particularly accurate and reliable sensor device for a vehicle for capacitively detecting input means. The object according to the invention is achieved by using respective second connections on the first sensor electrode and on the second sensor electrode and by means of corresponding methods for detecting the presence of input means and for detecting faults.
