1. A method for transmitting electromagnetic signals from a moving vehicle to a target device,
wherein the moving vehicle comprises a communication system, provided with a radiating system by which it receives and transmits electromagnetic signals, and the method comprises
performing an alignment step with the target device to establish a first communication direction with the target device,
communicating with the target device by orienting the radiating system in order to receive and transmit data along said first communication direction, and
performing a subsequent phase for maintaining the alignment with the target device in which
determining a position and an orientation of the vehicle, based on data measured by at least one sensor of the vehicle, said sensor being operatively connected to an electronic control unit of the vehicle configured to implement control and/or driving assistance functions of the vehicle based on information received from said sensor,
receiving dynamics information indicative of or adapted to predict a future position and orientation of a radiating system of the target device,
and further comprising
determining a future position and orientation of the radiating system based on the determined position and orientation of the vehicle,
determining a future position and orientation of the radiating system of the target vehicle based on the determined position and orientation of the target device,
determining a second communication direction which connects the future position of the radiating system to the future position of the radiating system of the target device, said second communication direction being determined by combining the future position and orientation of the radiating system with the dynamics information and
orienting the electromagnetic signals emitted by the radiating system of the vehicle on the basis of the determined direction of communication.
