Abstract
It is a concern that eco-driving vehicles, because those driving behaviors are different from other vehicles due to e.g. e-start, may inhibit smooth traffic flow. Therefore, it is necessary to study about cooperation in eco-driving by vehicle groups that were viewed with “vehicle-to-vehicle communication” and “road-to-vehicle communication”. From that background, this study aimed to: 1) Analyze fuel consumption rates and driving behaviors of multiple succeeding vehicles to follow an eco-driving vehicle. 2) Observe the impact of information on fuel consumption rate of the preceding vehicle to succeeding ones. As a result, the following findings were obtained: 1. By providing information to multiple following vehicles, the fuel consumption rate of the following vehicles can reduce. 2. When the information of fuel consumption of a preceding vehicle was provided to succeeding one, it was found that acceleration of following vehicles tended to be reduced. From the above, it is suggested that sharing the information on preceding vehicles was effective when vehicle groups were targeted.
