A device for coordinating a first vehicle with a transfer device and a second vehicle with a loading chamber that is filled by the transfer device includes a monitoring device for monitoring the transfer from the first vehicle to the second vehicle and a control unit. The control unit relies on the monitoring device to detect a position of an impact point of a load crop stream discharged from a transfer device of the first vehicle to the second vehicle and, in the event the detected position deviates from a target position, the control device sets the ground-speed differential to be different from zero until the detected position matches the target position.
