Rollover Causes • Excessive Speed on Ramps or Curves • Excessive Speed in Inclement weather • Swerving to Avoid Obstacles • Inattention • Fatigue • Turning too sharply Configurations 2S/1M, 2S/2M, 4S/2M Applications Vans, Reefer Units, Tankers, Flat Beds, Hazardous Material Haulers, B-Trains 12 © ZF Friedrichshafen AG Function: • Lateral acceleration calculated from side-to-side wheel speed differences and a lateral accelerometer • 4 wheel speed sensors required with tandem & tridem • 2 wheel speed sensors for single axle trailers • Load signal from suspension air bags or electronic suspension sensor • When a critical acceleration is detected (during evasive maneuver, etc.) the trailer brakes are automatically applied • Vehicle speed is reduced, lowering lateral acceleration • System can help prevent rollovers, it cannotcompletely eliminate occurrences • RSSplus is a driver aid, the driver remains the critical component • Laws of Physics prevail 13 How does Roll Stability for Trailers work Roll Stability for Trailers How does Roll Stability for Trailers work?
