Outline of Final Research Achievements

In order to analyze effective driving methods and beneficial changes for eco-driving using the eco-driving pilot program data with ITS. The results empirically indicated that effective eco-driving methods on highways was to keep speeds between 70 and 80 km/h. And high fuel economy improvement exceeding 30 % was mainly caused by decreasing idling consumption.
Regarding EV/HEV, the driver must always be aware of the range anxiety (RA) of the vehicle. To clarify the actual performance of the vehicle, electricity consumption rate (ECR) was calculated. The effect of speed management was evaluated by comparing the difference among ECRs. As the analysis results, the effect of speed management on the ECR to reduce RA was smaller than non-use of heater but larger than non-use of air conditioning. Three measures for non-use of the heater are common to those for improvement in fuel economy of engine vehicles and simple and easy solutions.
