Abstract: The present disclosure relates to establishing bidirectional communication between a brain wave processing device and a vehicle to control at least one vehicle component of the vehicle. For this purpose, a brain-computer communication channel is provided between the brain wave processing device and the respective vehicle component. Subsequently, a control signal is determined as a function of a brain wave of the operator of the brain wave processing device and transmitted via the brain-computer communication channel to adapt at least one operating parameter of the respective vehicle component. This causes a change in the operating state of the respective vehicle component. Depending on this, an output signal is generated and is assigned to the change in the operating state of the vehicle component. This output signal is transmitted back to the brain wave processing device via the brain-computer communication channel and is output to the operator by means of an output unit of the brain wave processing device.
