Abstract
A method for increasing the measuring accuracy for a limited path is described, where a map of the actual geometric path that is stored in a memory is obtained in a “learning phase.” In addition, a method for better controlling a camshaft offset in a combustion engine is described.

A method for increasing measuring accuracy for a limited path by using a measuring system having a sensor and a scale having path events, the method comprising the steps of:
- during at least one learning phase, moving the sensor relative to the scale so as to form a map of actual geometric intervals of the path events;
- and
- subsequent to the at least one learning phase, moving the sensor and the scale relative to each other and detecting the path events during a measuring phase, the path events being reproduced by the sensor as electric signals, and determining a measured path as a function of the detecting of the path events and the map.
A method for increasing measuring accuracy for a limited path by using a measuring system having a sensor and a scale having path events, the method comprising the steps of:
- during at least one learning phase, moving the sensor relative to the scale so as to form first stored values, a map of actual geometric intervals of the path events over the limited path capable of being formed as a function of the first stored values;
- and
- subsequent to the at least one learning phase, moving the sensor and the scale relative to each other and detecting the path events during a measuring phase, second values corresponding to the path events during the measuring phase being generated as function of electric signals from the sensor;
- and
- determining a geometric location along the limited path of at least one of the path events detected during the measuring phase as a function of the first stored values and the second values.
