This year, in the third year of FutureTruck competition, the Ohio State University team has taken the challenge to convert a 2002 Ford Explorer into a more fuel efficient and environmentally friendly SUV. This goal was achieved by use of a post-transmission, charge sustaining, parallel hybrid diesel-electric drivetrain. The main power source is a 2.5-liter, 103 kW advanced CIDI engine manufactured by VM Motori. A 55 kW Ecostar AC induction electric motor provides the supplemental power. The powertrain is managed by a state of the art supervisory control system which optimizes powertrain characteristics using advanced energy management and emission control algorithms. A unique driver interface implementing advanced telematics, and an interior designed specifically to reduce weight and be more environmentally friendly add to the utility of the vehicle as well as the consumer appeal.

The rise of automation in the automotive industry has ensured significant progress in vehicle safety and infrastructure. During the transition to full autonomy, the driver is often the redundancy and safety feature in the event of a hazard or automation error. Understanding driver behavior in the transition from non-driver to driver is important for safety. Proper handling of transitions will be more critical as these events become less common and users trust automated driving systems. This research investigates the case of SAE level-3 automated driving systems, where the driver need not constantly pay attention but is responsible for reaction during hazards. Findings include quantitative and qualitative assessment of various warning modes for a distracted driver responding to an automated driving failure situation. Driver response time and behavior for these events are compared to instances with minimal warning systems.
