This study was conducted by researchers at the National Advanced Driving Simulator (NADS) at the University of Iowa. The primary objective of this research project was to assess the effectiveness of tractor electronic stability control systems on heavy trucks in terms of reducing the incidences of rollovers and jackknifes. This study was completed using the NADS-1, a high-fidelity full motion simulator instrumented with a functioning 1999 Freightliner Century Class cab with an Eaton Fuller 9-speed transmission. A hardware-in-the-loop (HIL) solution was developed in partnership with Meritor WABCO to integrate commercial stability control systems into the simulation environment. The experiment is a split plot; the between-subjects independent variable is ESC Condition. Five study drives were completed by each participant; these drives were divided into two distinct groups: those designed to induce the potential for a rollover utilizing a high coefficient of friction roadway, and those designed to induce the potential for a jackknife using a low coefficient of friction roadway. Overall, potential benefits were found for both the RSC and the RSC+YSC systems under differing conditions for helping drivers maintain vehicle control. It was observed that the performance of both systems was highly dependent on drivers speed. RSC showed strong reductions of rollovers in geometry-based situations such as tight curves and exit ramps. Additionally, drivers with the RSC+YSC system were six times more likely to avoid a jackknife than were drivers without a system when encountering similar conditions at event onset.
