the invention relates to a device (1) on a vehicle (2) with a hydraulic bet u00e4tigungseinheit (3) to control the operation of a anbauger u00e4ts (4) of the vehicle (2),comprehensive, at least a lageerfassungseinheit (7) with at least one camera (8), at least one lageerfassungsmarkierung (9a, 9b, 9c)an evaluation unit (10) and a datenleitende connection (11) to a hydraulic bet u00e4tigungseinheit (3) assigned unit (13).with the at least one camera (8) in the operation, so the at least one lageerfassungsmarkierung (9a, 9b, 9c) and the floor (5) is addressed.a tendency of anbauger u00e4ts (4) about a transverse axis (19) are detectable and the hydraulic bet u00e4tigungseinheit (3), a lifting mechanism (14) for the tool (4) and a oberlenkerzylinder (18) umfasst.further, a procedure is proposed.and through such a lageerfassungseinrichtung (7) the location of the anbauger u00e4ts (4) can be determined according to the position and by an adequate operation of the hydraulic controlsunit (3) is adjustable.
