    Abstract: An arrangement of a steering device is provided for use with a steering system of a vehicle, which includes a rigid steering part and a rotatable steering part. The arrangement includes a steering wheel coupled to the rotatable steering part via a transmission, and a motor configured to rotate the rotatable steering part. The transmission includes a first machine element, a second machine element, and a third machine element. The first machine element is rotationally connected to the rotatable steering part, the second machine element is rotationally connected to the steering wheel, and the third machine element couples the first machine element to the second machine element. The third machine element is mounted for rotation about an axis of rotation, wherein the axis of rotation is arranged rigidly relative to the rigid steering part.

    Abstract: A method for determining a risk of instability of a calculation of an angle ϕ of a steering shaft of a motor vehicle can be employed where a first gear wheel is fixed to the steering shaft and cooperates with a second gear wheel and a third gear wheel, which are smaller than the first gear wheel. The number of teeth of the first gear wheel is n. The number of teeth of the second gear wheel is m. And the number of teeth of the third gear wheel is m+1. The angles θ and ψ of the two smaller gear wheels are determined and the angular position ϕ of the steering shaft is calculated by evaluating the equation
