混合动力车辆——现状与发展(英文)

Hybrid Electric Vehicles——Current Status and Future Trend

第一辆混合动力汽车(HEV)诞生100多年了。近15年来,技术手段趋于成熟,在美国、日本和中国有很多混合动力乘用车投入使用。然而,在中国和美国,混合动力乘用车的市场份额依然很小。为使混合动力车辆更加成功,与传统内燃机车辆相比具竞争性,混合动力车就必须价格更便宜、性能更好。本文回顾了混合动力车辆的现状与发展趋势,并讨论了几种可以运行多行星齿轮排、多模式和全轮驱动的技术方案,这些技术方案将有助于实现混合动力车辆性能突破。这些方案对于将混合动力车辆技术从乘用车扩展到轻型卡车(LTs)和运动型多用途汽车(SUVs)十分重要。

The first hybrid electric vehicle （HEV） was built more than 100 years ago. Over the last 15 years, the technologies have matured and many hybrid passenger cars are offered in US, Japan and China. However their market shares are still very small in both China and in the US. To make HEVs more successful, they must become more affordable, and have better performance, so that they can become more competitive compared with the traditional powertrain vehicles that only run on international combustion engines. This paper reviews the current status, and discusses several technology concepts to enable multi-planetary gear, multi-mode and all-wheel drive operations. These concepts likely will help to achieve the needed performance breakthrough. These concepts are especially important to extend the HEV technologies beyond passenger cars, to light trucks （LTs） and Sport Utility Vehicles （SUVs）.
