Abstract
In a truck, consisting of a towing vehicle and at least one trailer vehicle, to transmit telematics data to a vehicle-remote telematics portal the telematics data from the trailer vehicle(s) are transmitted via a cable connection to the towing vehicle and sent from the towing vehicle, together with the telematics data from the towing vehicle, to the vehicle-remote telematics portal. Only the towing vehicle has an electronic telematics controller, and the cable connection is used as a PLC line in order to transmit the telematics data from the trailer vehicle(s) to the towing vehicle without the need for additional cable connections.
