Abstract
A system for controlling an industrial truck with a drive portion including a traction drive portion, a steering portion, and a load portion, comprises a portable transmitting unit configured to be positioned away from the industrial truck. The system further comprises at least three transmitting and receiving units positioned in a predetermined spatial arrangement with respect to one another on the drive portion. An evaluation unit is provided that is configured to determine a position of the portable transmitting and receiving unit relative to the industrial truck by measuring signal propagation times. The industrial truck further comprises a control unit configured to send a control command for traction drive and/or steering if the relative position of the portable transmitting and receiving unit is located within a predetermined spatial region relative to the industrial truck.
