| Abstract(J) | 欧米では、高効率な前照灯やオルタネータ等、オフサイクルにおいて燃費向上が見込める技術を積極的に評価しており、日本でも評価制度の導入が検討されている。本稿では、モード走行時に前照灯を点灯した際の燃費影響を評価するとともに、日本市場における前照灯の使用頻度を推定することにより、実燃費への影響を試算した。 Translation |
| Abstract(E) | Headlamps are usually not activated on fuel economy tests in type approval. However, headlamp usage would affect the fuel economy due to the increase of energy consumption and the ineffectiveness of lead-acid battery charging control in conventional internal combustion engine (ICE) vehicles. In this paper, the influence of headlamp usage on the actual fuel economy was investigated by driving cycle tests on a chassis dynamometer using an ICE vehicle and a survey for headlamp use frequency based on vehicle data in the Japanese market. As a result, the actual fuel economy was estimated to reduce by about 1.2% - 2.0% due to the effects of headlamp usage. |
