Abstract: There is disclosed a method for the adjustment of an optical row of sensors which, for guiding a driverless vehicle along an optical guideway, is secured at the vehicle transversly with respect to the vehicle travel direction. Known systems attempt to accomplish a compensation of component tolerances by carrying out an adjustment between the measurement signals of the sensors. However, this leads to inaccurate measurement values. A post-adjustment of a contrast value is not contemplated with these systems. The invention eliminates these inaccuracies and affords an exact post-adjustment. On the one hand, this is attained in that the sensors are adjusted by a calibration surface and the adjustment values for controlling the sensors are stored in an adjustment table. On the other hand, it is proposed to perform the adjustment operation at the site of use of the equipment and to provide an adaptive post-adjustment of the thus set adjustment table.
