Eco-driving performance assessment with in-car visual and haptic feedback assistance

Abstract : In this experiment, 28 participants completed an urban driving task in the CARDS simulator at Renault’s Technical Centre for Simulation. This simulator, based on the SCANeR2© software package, provides a 150° field of view in a fully instrumented cockpit. Two different eco-driving assistance devices were added: a 7 inches display on the mid-console, and a force feedback system on the gas pedal. The feedback information was computed by comparing the car’s instant acceleration with an optimal acceleration level based on a proprietary consumption model of a Renault diesel engine. Basic eco-driving behaviors, like gear-shifting under 2000 Rpm, allows significant decrease of polluting emissions. Assisting drivers with visual, haptic, or visual-haptic on-board devices, in addition to low engine speed verbal instructions, lead to supplementary significant savings of polluting emissions. There is no significant difference between assistance feedback type; suggesting that haptic feedback provides the same ecoperformance as visual feedback. In particular, subjects show good adaptation to the haptic feedback pedal at first utilization of the system. They apparently relied more on haptic modality to achieve the eco-driving task, when they used both visual and haptic assistance.
