Threat-Based Semi-Autonomous Operator Assistance Algorithms for Ground Vehicles

Abstract : This research has developed an intelligent co-pilot operator assistance algorithm for manned or teleoperated ground vehicles. A large-scale experimental study was performed on an outdoor vehicle to test the hypothesis that the semi-autonomous control framework could both prevent vehicle collisions and increase travel speed. Statistically significant results, gathered over a large population of operators, showed a substantial increase in vehicle speed and safety when guided by the semi-autonomous control framework. Other results showed an increasing acceptance of the control technology as additional feedback modalities (i.e. visual, tactile) were provided to the operator.
