• Description:
  Tractor instability is a major cause of serious injuries and fatalities in the agricultural industry. Thus, preventing tractor rollover can have a vital impact in reducing injury risk and saving lives of operators. This study presents preliminary experimental results on the perception of tilt angles. Using a novel tractor driving simulator developed at Penn State, a testing protocol was implemented in order to evaluate the ability of subjects to remember poses at various roll-pitch combinations. Results suggest that roll and pitch are both systematically underestimated, the former more severely than the latter. They also show no statistically significant correlation between the effect of pitch angles on the perception of roll, but do provide an upper bound on typical perceptual errors. These pilot-test results will serve as the basis of a comprehensive study with a wider subject pool. The bigger goal in this effort is to develop rollover alert systems that can prevent these accidents from happening. In that regard, the data obtained from this experiment can be useful in the design and tuning of predictive rollover alerts that promote safe operation of farm tractors, using human perception errors of roll and pitch to guide the thresholds at which warnings should be initiated in each of these directions.
