With European regulations mandating a vehicle stability function with roll-over control for semi-trailers and heavy trailers, both with air suspension and up to three axles, with effect from July 2010, WABCO has received approval for its system from German authority TUV Nord.
As a result, WABCO RSS for trailers is the industry’s first trailer roll-over control approved for use in all 27 countries of the European Union and in 20 other countries worldwide in accordance with the United Nations Economic Commission for Europe’s Regulation 13 for braking.
Integrated with WABCO’s Trailer EBS system, RSS reliably prevents vehicle roll-over within physical limits, by analysing vehicle data such as wheel speed, load and lateral acceleration and then automatically applying the brakes to reduce speed and re-stabilise the vehicle.
Beyond the scope of the EU’s new regulation, WABCO also offers RSS for trailers with mechanical suspension, lift axles and steering axles, and the company can adapt RSS for special vehicle types such as non-standard flatbed semi-trailers with independent wheel suspension.
