シリーズハイブリッド車の実路エコドライブ手法の検討

抄録

In this study, we conducted real road tests using a series HV (hybrid) that is popular in Japan, and compared the results with the analysis results of a series-parallel HV that the authors have previously investigated, with the aim of proposing an eco-driving method for series HV on real roads. As a result of a comparative analysis of the fuel efficiency of series HV and series-parallel HV on real roads, we found that the series HV has less change in fuel efficiency in urban areas, rural areas, and on highways compared to the series-parallel HV. In addition, for series HV, there is no correlation between fuel efficiency and driving conditions such as frequency of acceleration and deceleration. Therefore, Series HV is considered to be a system that has little change in fuel efficiency in response to changes in vehicle speed due to traffic flow on real roads and changes in driving conditions such as the frequency of acceleration and deceleration due to driving operations by the driver.
