Abstract
A method for aligning a calibration device for calibrating a vehicle environmental sensor of a vehicle, and a device for carrying out such a method. The method includes: measuring a temporal curve of at least one measurement point using the camera, determining the geometrical driving axis from the temporal curve of the at least one measurement point, measuring a first and a second lateral distance value of the vehicle using the distance sensors at a measurement time, determining a center of a vehicle axle at the measurement time on the basis of the ascertained lateral distance values, correlating the geometrical driving axis to the center of the vehicle axle at the measurement time and determining an axially centric geometrical driving axis, and aligning the calibration device in correspondence to the ascertained axially centric geometrical driving axis.
