Abstract
A method and a device for acquiring a value of a defined reference point of a first variable which is measured by an incrementally measuring sensor of a motor vehicle are disclosed. The method includes the step of acquiring intermediate values of the defined reference point in at least two detection modules using at least one second measured variable, wherein each detection module is adapted to determine a value of the defined reference point of the first variable in a pre-defined driving situation. A quality level for each intermediate value is determined. The quality levels of the intermediate values are compared. The value of the defined reference point is determined from the acquired intermediate values in accordance with a result of the compared quality levels.

37. A device for acquiring a value of a defined reference point of a first variable which is measured by an incrementally measuring sensor of a motor vehicle, said device comprising:
-
at least two detection modules that are each configured to; (i) acquire an intermediate value of the defined reference point using at least one second measured variable, (ii) determine the value of the defined reference point of the first variable in a predefined driving situation of the vehicle, and (iii) determine a quality level for the acquired intermediate value; and an arbitration device that is configured to compare the quality levels of the intermediate values and determine the value of the defined reference point from the acquired intermediate values based upon a result of the comparison of the quality levels.
