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.

A safety device includes a safety module and a safety control module in order to reduce a speed of an unwanted clutch engagement when a malfunction of a motor for a clutch control actuator occurs, such as by the power supply for the motor being interrupted, so that a driver can have more time to react in such situation.

Device and method to reduce clutch engagement speed

A clutch system for closing and interrupting a force flow includes a clutch actuator that can have a pressure medium applied thereto, a first electrically actuatable valve device and a second electrically actuatable valve device. Pressure medium can be fed into a switching chamber of the clutch actuator by the first valve device for building up pressure, and pressure medium can be discharged again by the second valve device for releasing pressure. The clutch system interrupts or closes the force flow at a pressure P&#x2267;Pd in the switching chamber. A method for operating the clutch system for closing and interrupting a force flow prevents a subsequent pressure buildup in the switching chamber sufficient for actuating the clutch system if the first valve device and the second valve device malfunction.
