Abstract

A method/system for calibrating a vehicle sensor, including detecting data about the vehicle's surroundings using the sensor, and ascertaining stationary structures using the detected first data pieces. Stationary structures are selected for later calibration, and potential parking positions are determined. A parking position is selected from the potential parking positions so that after parking, stationary structures selected for a calibration of the sensor are in the sensor's field of vision. The vehicle is parked, and the position of the stationary structures selected for the calibration of the sensor is stored. After the vehicle start, second data pieces about the vehicle's surroundings are detected using the sensor, and instantaneous positions of the selected stationary structures are ascertained using the detected second data pieces. The instantaneous position are compared with the stored positions, and deviations between the instantaneous positions and the stored positions determined. The sensor is calibrated using the determined deviations.
