Abstract: A rotary angle encoder in which the adjustment of the sensor signal desired in the starting position can be changed by simple manipulation. In the rotary angle encoder set forth herein, upon assembly, the coupling is slid only partially onto a cylindrical shaft connected to the sensor part in a first position. In this first position, the coupling can be rotated in relation to the sensor part. Then the sensor signal desired in the starting position is set and after that, the coupling is slid still further onto the cylindrical shaft so that an unintentional rotation of both parts in relation to each other is not possible after the adjustment is complete. The rotary angle encoder is provided for controlling the power of a vehicle drive unit.

Abstract: In prior rotary angle encoders, the adjustment of the sensor signal desired in the starting position is very difficult. Furthermore, this sensor signal can be changed by simple manipulation.

Abstract: An accelerator pedal module actuated by the driver's foot for controlling the output of a driving engine. The accelerator pedal module includes a friction element for attaining frictional hysteresis directly at a bearing point on which the pedal lever is supported. The number of components required is thus reduced considerably. The accelerator pedal module is contemplated for controlling the output of a driving engine of the vehicle.

Abstract: An accelerator pedal modules for a motor vehicle which is actuated by the driver's foot. A sensor is disposed in a common housing together with other components, a restoring spring assembly, a kickdown mechanism and an end switch secured relative to the accelerator pedal and each other. The sensor is disposed in a separate housing, and by a suitable embodiment of the pedal lever, the accelerator pedal module can be adapted to a specific vehicle without modification of the sensor. This makes it possible to produce a standard sensor in large quantities. When the accelerator pedal module is activated the pedal activates the sensor which sends an electrical signal to a controller via electrical lines. The sensor includes a restoring spring which forces the pedal back to its normal rest position. The device includes a friction device which causes a friction in order to apply a force against momentum of the pedal. The controller controls an output of a driving engine.
