Method and device for determining an absolute value of a variable
First Claim
1. A method 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 method being performed by a processor of the motor vehicle and comprising the steps of:
- (a) acquiring, by the processor, intermediate values of the defined reference point in at least two detection modules using at least one second measured variable, wherein each detection module has a predefined ranking and is adapted to determine a value of the defined reference point of the first variable in a respective pre-defined driving situation,(b) determining, by the processor, a quality level for each intermediate value based on driving conditions,(c) comparing, by the processor, the quality levels of the intermediate values, and(d) determining, by the processor, the value of the defined reference point from the acquired intermediate values based on the comparison of the quality levels and the ranking of the detection modules.

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.
