METHOD FOR OPERATING A DRIVER ASSISTANCE SYSTEM FOR MOTOR VEHICLES

A method for operating a driver assistance system for motor vehicles which comprises a radar sensor and has a variable functional scope, with continuous recalibration of the radar sensor in order to compensate for adjustment errors during ongoing operation, characterized by the following steps: estimating the adjustment error on the basis of a measurement over a limited first operating time period(S3), restricting the functional scope of the driver assistance system depending on the estimated adjustment error (S5), continuing the measurement during operation with a restricted functional scopewithin a second operating time period (42), for improving the estimation accuracy of the adjustment error (S7), and extending the functional scope according to the improvement in the estimation accuracy (S9). 本发明涉及一种用于运行车辆的驾驶员辅助系统的方法，所述驾驶员辅助系统具有雷达传感器并且有功能范围，所述方法具有在持续运行时连续地再校准雷达传感器以补偿校正误差的功能，其特征在于以下步骤：在受限的第一运行时段基于测量评估校正误差(S3)，根据所评估的校正误差限制驾驶员辅助系统的功能范围(S5)，在第二运行时段(42)内在以受限的功能范围运行期间继续进行测量，以改善所述校正误差的评估精度(S7)，和根据评估精度的改善扩展功能范围(S
