For trailers equipped with WABCO's Trailer Electronic Braking System (Trailer EBS) , WABCO offers an advanced Roll Stablity Support (RSS) logic control unit, which reliably prevents vehicle roll-over within physical limits. RSS is a function integrated in the software and hardware of the EBS modulator. The system assesses the vehicle data such as wheel speed, load information and by means of an integrated sensor, transverse acceleration data. By analyzing this data quickly and effectively, the vehicle ECU detects the chances of vehicle roll-over and automatically applies the brakes. Although no system can fully defy the laws of physics and a trailer can still tip if the side forces are extreme or increase significantly during braking, WABCO's RSS significantly reduces the risk.
