Test Track Lateral Stability Performance of Motorcoaches Equipped with Electronic Stability Control Systems

This article presents findings of test track research performed with three class 8 motorcoaches equipped with electronic stability control (ESC). Using maneuvers from previous tractor semitrailer stability control research, test track performance of stability control was assessed for motorcoaches that included a 2007 MICI D4500 and a 2009 Provost H3. Roll and yaw stability performance was measured via slowly increasing steer test (SIS), constant radius (CR) increasing velocity test, ramp steer maneuver (RSM), half sine with dwell (HSWD), sine with dwell (SWD), and ramp with dwell (RWD) maneuvers. Findings indicated that ESC systems could exert control over the engine/power unit and of foundation braking control to increase stability, while maintaining the same level of maneuverability or responsiveness.
