Abstract
The subject matter of the invention is a motor vehicle closing device with a positioning element ( ) which turns around one axis of rotation ( ) or which moves linearly along one lengthwise axis and which has a position which is to be ascertained, and with a position detection means ( ) which works without contact and which is located on the path of motion of the positioning element ( ) (or on the positioning element itself). It thus lends itself to “diagnosis” by the fact that on the positioning element ( ) (or on the path of movement of the positioning element ) in the direction of its motion there are several passive position detection elements ( ) in succession and that position detection takes place by counting the signals of the position detection elements ( ) by the position detection means ( ). In particular it is provided that the position detection means ( ) has a sensor which is sensitive to magnetic fields, especially a Hall sensor, a reed contact or a magnetoresistive sensor and the position detection elements ( ) are made as alternatingly magnetic and nomnagnetic pole zones or pole zones which are magnetized with changing polarity.
