A communication interface is provided between a towing vehicle and a trailer, which are connected by a plurality of connectors compliant with standards selected from ISO12098, ISO7638, ISO1185, ISO3731, ISO11446. Digital signals are transmissible between the towing vehicle and the towed vehicle via an ISO11992-3 CAN bus. Pins on the towing vehicles are connected to pins on the towed vehicle by twisted pairs of wires adapted to carry a digital differential signal to provide higher speed data transmission between the vehicles.

An apparatus controls a system of a plurality of motor units, which are operated by way of output-stage units. Fewer output-stage units than motor units are provided. The apparatus has a switching unit, which is configured to switch the one or more output-stage units between the motor units.

Electronics having one or more output-stage units for the operation of two or more motor units

A system and method for controlling communications between members of a tractor-trailer along a power line extending between the members are provided. The system includes an input signal conditioning circuit including an amplifier and conditioning stage configured to convert an analog input signal from the power line to a digital input signal. The system further includes a controller configured to receive the digital input signal, identify a communication protocol for the analog input signal from among a plurality of communication protocols responsive to the digital input signal and decode the digital input signal using the communication protocol. The controller may also identify a communication protocol for an output signal on the power line from among the plurality of communication protocols and encode a digital communication using the communication protocol.
