Abstract:The introduction of electric vehicles is a way to reduce the high contributions of the transport sector to CO2 emissions. Eco-driving feedback is often employed to reduce range anxiety in electric vehicles, but can also affect cognitive workload. Increases in cognitive workload pose safety risks when they interfere with driving. In the current study, effects of range anxiety and eco-driving feedback on cognitive workload are investigated. For this, 23 participants holding a driver’s license took part in a VR-simulated experiment. They drove for five minutes in each of the four conditions. These were divided into low range (LR) and high range (HR) situations and depending on whether efficiency feedback was shown (marked by adding /F to the condition). This resulted in the conditions of HR/F, LR/F, HR, and LR. After each condition, levels of range anxiety and cognitive workload were measured. Range anxiety and cognitive workload were strongly correlated (r=.66). Cognitive workload was significantly higher for the conditions in which eco-driving feedback was shown. Eco-driving feedback did not moderate the effect of range anxiety on cognitive workload. These findings inform the design of in-vehicle information systems in electric vehicles. Future research should investigate ways to reduce effects on cognitive workload.
