Abstract: The invention relates to a sensor unit, integrated in a pedal-box, for the determination of the angular position of a pedal lever (1), in the form of an inductive non-contact separation sensor, comprising a stationary sensor head (3) and a sensor element (4), moving with the pedal lever (1). The sensor head (3), oriented transverse to the pedal axis (6), is directed at the sensor element (4), which moves with the pivoting pedal lever (1) in the direction of the main sensor, such as to alter the separation. The separation of the sensor head (3) and the sensor element (4) influences the electrical signal generated by the sensor head (3), from the values of which, inferences can be drawn about the position of the pedal. Two adjacent pedal levers (1) are arranged on a common housing (5), each with one of the integrated sensor heads (3).

Abstract: A setting device for a vehicle having a mechanically adjustable part in which a sensor assigned to the mechanically adjustable part generates sensor signals corresponding to the positions of the part. An initial range of the sensor values is assigned to an inoperative position of the part and covers the varying initial positions of the part. An evaluation device stores a longer constant signal in the initial range as an intermediate value. A longer constant sensor signal is compared with the intermediate value after the initial range is exceeded and after the subsequent return into this range. If it is established that both values are approximately of the same magnitude, the evaluation device stores this value as an initial value. As a result, the inoperative position of the part is reliably verified without the use of additional auxiliary components or steps.

Abstract: The sensor values (s) of a sensor device (6) exhibit, in the delivered condition, sensor values in a delivered scale that are reduced by about 50%, which document at the same the condition at the time of delivery. After the installation in a device, an initialization and justification process of the sensor device is started on crossing of the threshold values (t), in course of which the delivered scale (ds) is converted into a normal operating scale (os).

Abstract: A carrier (2) with optically transilluminated position marks (3) can be positioned between a source of light (5) and an optical detector (4). The position mark (3) is built as an optical element that deflects the beam of light, which leads to significant variations in the intensity of light (8) at the central area of the image in the detector plane. With that, it is possible with less fabrication costs to furnish a measuring device that is robust against interfering influences.

Abstract: The invention relates to a pedal system for a motor vehicle comprising a displacement sensor. Said sensor is used for determining the angular position of a foot pedal (1) and is provided as an inductive sensor which comprises a stationary coil part (3) and a metal part (4) that is displaced with the foot pedal (1). The distance of the metal part (4) from the coil part (3) alters the electric relationships from which corresponding measured values can be derived. This results in reducing the production complexity of the pedal system and in improving the functional reliability of the sensor.

Abstract: A sensor (3, 4) is assigned to a mechanically adjustable part (e.g. 1) and generates sensor signals corresponding to the positions of the part. An initial range (sr) of the sensor values (s) is assigned to an inoperative position of the part and covers the varying initial positions of the part (e.g. 1). An evaluation device (9) stores a longer constant signal in the initial range as an intermediate value (st). A longer constant sensor signal is compared with the intermediate value (st) after the initial range (sr) is exceeded and after the subsequent return into this range. If it is established that both values are approximately of the same magnitude, the evaluation device stores this value as an initial value (sp, spn). As a result, the inoperative position of the part is reliably verified without the use of additional auxiliary means.
