Abstract: A method for operating a driver assistance system for motor vehicles which has a radar sensor and a variable scope of functionality, with continuous recalibration of the radar sensor in order to compensate for alignment errors during operation, characterized by the following steps: estimating the alignment error based on a measurement over a limited first operating time period; limiting the scope of functionality of the driver assistance system depending on the estimated alignment error; continuing to measure during operation with a limited scope of functionality within a second operating time period, in order to improve the estimation accuracy of the alignment error; and expanding the scope of functionality in accordance with the improvement in estimation accuracy.
