Continental has added a new feature to its successful ContiPressureCheck™ tire pressure monitoring system. Automatic Trailer Learning (ATL) can now monitor the condition of tires on trucks and trailers much more easily and practically. Semitrailer tractors with ATL can automatically and wirelessly detect each trailer tire equipped with ContiPressureCheck sensors. This means that the tire pressure monitoring for the trailer matches up with that of the tractor vehicle, even if the semitrailer is frequently changed.

The pressure and temperature data from all twelve tires on the truck and trailer combination are reliably transferred to the display in the cab. The wiring for the ContiPressureCheck system with ATL is fitted exclusively to the tractor vehicle. Once the ContiPressureCheck sensors are fitted in the tires, no further installation work is required on the trailer. It only takes the system a few minutes to detect a newly coupled trailer and display the initial data. This happens while the vehicle is in motion and without the driver having to do anything. When the vehicle has been stationary for more than 15 minutes, ContiPressureCheck™ checks again whether the tractor vehicle is coupled to a trailer and, if so, to which one. If a new trailer is detected it sends the tire data to the cockpit. Continental will be presenting the new Automatic Trailer Learning function to the general public for the first time at the IAA Commercial Vehicles Show 2014 in Hanover.

The tire manufacturer brought ContiPressureCheck™ to market in 2013. This modern tire pressure monitoring system essentially consists of a battery-operated sensor module in each tire, a receiver on the vehicle frame, and a display on the dashboard. The sensor module measures about two centimeters across and weighs just 26 grams. It contains sensors for data acquisition, a processor, and a transmitter, all housed in a rubber bracket that is fixed to the inside of the tire tread. When the tire is changed, it can be removed from the bracket and used on the new tire. The battery lasts about six years or 600,000 km. ContiPressureCheck™ works with all tire brands and on all truck-trailer combinations and buses.
