Abstract

A sensor for a vehicle includes a sensor housing, a surface of which sensor housing has at least three areas defining at least three reference measuring fields. Positions of the at least three reference measuring fields define a reference plane. The reference measuring fields have (i) a surface texture which enables tactile position determination of the reference measuring fields, and/or (ii) a surface characteristic which enables optical position determination. The detected positions of the reference measuring fields are used to define the reference plane. A mechanical sensor axis of the target sensor is defined as extending orthogonally to the reference plane. The mechanical sensor axis is used to (a) ascertain an angle of deviation between the mechanical sensor axis and a known sensor axis of the sensor, and/or (b) align the mechanical sensor axis to a travel axis of the vehicle.
