The invention relates to an adaptive absolute steering sensor for the absolute determination of a turning angle, especially for determining the steering angle in a motor vehicle by way of a code applied across a 360&deg; angular range for a determining the angle. The code and a sensor system are arranged in such a way that they are able to rotate in relation to each other. Absolute determination of the angle is carried out by reading the contrast information using a micro processor which determines both the angular position of the code and the fine resolution of the angles on the basis of the relative position of the recognized angle to the image on the photodetector system. At the same time the overall function of the system is verified and adjusted during each measurement. The code is determined using a photodetector system positioned in a single place, and used for determining the angle, whereby an unbroken segment of code track is shown on at least one photodetector line and at least one code word is detected to which corresponds a predetermined angle. The position of the code word in relation to the fixed position of the photodetector line is measured.

Adaptive absolute steering angle sensor

The invention relates to a heating element for a part of an automobile which is held, especially the steering wheel. The heating element consists of a textile support with at least one heating resistor. According to the invention, a knitted textile support is used.

Heating element for a part of an automobile which is held, especially the steering wheel

The invention relates to a heating device for a moveable part of a motor vehicle such as an automobile which can be held, such as a steering wheel. The heater is connected to a source of electrical energy in a stationary part of the vehicle by a contact unit having a stator and a rotor. A voltage converter of the heating device is provided in the stationary part of the vehicle, before the contact unit or in the stator of the contact unit. The voltage converter enables the generation of a higher voltage than the normal 12 volt standard voltage of the vehicle.
