This study performs an effects analysis of the hybrid conversion of a light-duty diesel truck depending on driving style. The experimental route is extracted from real delivery routes, and multiple drivers drive the route several times before and after the conversion. The results confirm that the fuel economy is improved by 24.3% on average after the conversion, and the fuel economy before and after the conversion is most strongly dependent on average engine speed and regenerative braking ratio, respectively. This different dependence on the driving style parameters is analyzed in relation to the control strategy and powertrain of the converted truck. An additional experiment reveals that the fuel economy of the converted truck can be further improved by 13.3% when visual feedback is provided to the unaware driver for correcting driving styles. These findings can be utilized to improve the performance of hybrid electric vehicles for various driving styles.

轻型柴油卡车混合动力转换取决于驾驶风格的效果分析

本研究根据驾驶风格对轻型柴油卡车的混合动力转换进行了效果分析。实验路线是从真实的配送路线中提取出来的,由多名司机在转换前后多次驾驶该路线。结果证实,改装后燃油经济性平均提高了24.3%,改装前后的燃油经济性分别最强烈地依赖于平均发动机转速和再生制动比。这种对驾驶风格参数的不同依赖性与改装卡车的控制策略和动力系统有关。一项额外的实验表明,当向不知情的驾驶员提供视觉反馈以纠正驾驶风格时,改装卡车的燃油经济性可以进一步提高 13.3%。
