Method for operating a transport vehicle for the interference-free transportation of load racks in industrial buildings by way of a partially autonomous driving operation, said method having the following features: a) a control centre in a storage region receives the order to ensure that a specific load rack having goods for transportation situated on said load rack is transported to a specific destination; b) the control centre determines which transport vehicle, by virtue of the current location and present order status thereof, is capable of most rapidly fulfilling the required order; c) a specific transport vehicle thereupon receives from the control centre the order to locate a specific load rack in a specific area of a comparatively large floor space of a storage region, to receive this load rack, and to drive this load rack having the goods for transportation situated thereon to a specific storage space; d) the transport vehicle selected by the control centre receives the instructions, as determined by means of a specific route-algorithm, in terms of the route to be travelled and of the speed to be travelled in each section of the route so as to reach the immediate destination within a specific time window; e) the respective transport vehicle by means of a 3D scanner and/or a light field sensor determines the load rack to be received, selects a suitable initial position for receiving the load rack, travels below the latter and lifts the latter for onward transportation; f) the respective transport vehicle awaits the instructions from the control centre and commences the return journey according to the instructions received, characterized in that the industrial buildings have radio shadow areas and, with a view to communicating in a corresponding manner, at least one further transport vehicle is integrated by means of a corresponding transmitter and receiver installation so as to bypass the radio shadow areas; wherein a vehicle control unit of the transport vehicle by way of an absent feedback signal can identify a loss of a direct data connection to the control centre and, having identified the loss of the direct data connection, emits a corresponding message which can be detected by at least one further transport vehicle, and upon the corresponding message having been received by one of the further transport vehicles, the further transport vehicle as a mobile transmitting and receiving installation, in particular as a mobile WLAN hotspot, reestablishes the lost direct data connection to the control centre as an indirect data connection. a) a control centre in a storage region receives the order to ensure that a specific load rack having goods for transportation situated on said load rack is transported to a specific destination; b) the control centre determines which transport vehicle, by virtue of the current location and present order status thereof, is capable of most rapidly fulfilling the required order; c) a specific transport vehicle thereupon receives from the control centre the order to locate a specific load rack in a specific area of a comparatively large floor space of a storage region, to receive this load rack, and to drive this load rack having the goods for transportation situated thereon to a specific storage space; d) the transport vehicle selected by the control centre receives the instructions, as determined by means of a specific route-algorithm, in terms of the route to be travelled and of the speed to be travelled in each section of the route so as to reach the immediate destination within a specific time window; e) the respective transport vehicle by means of a 3D scanner and/or a light field sensor determines the load rack to be received, selects a suitable initial position for receiving the load rack, travels below the latter and lifts the latter for onward transportation; f) the respective transport vehicle awaits the instructions from the control centre and commences the return journey according to the instructions received, characterized in that
