Abstract

In a method for determining input data of a driver assistance unit, information data are provided, which were determined as a function of a measurement signal of a first sensor using a predefined first calculation rule. Raw data are provided, which are representative of a measurement signal of the first and/or a second sensor. The plausibility data are determined as a function of the raw data using a predefined second calculation rule. Fusion data, which represent information data that have been checked for plausibility, are determined as a function of the information data and the plausibility data. The fusion data are provided as the input data to the driver assistance unit.

Claims
