摘要

欧盟(NEDC -新欧洲驾驶循环)型式认可试验中预定的换挡点对当今手动变速器的技术设计影响很大。大多数制造商选择一个较长的总传动比，以达到节省燃料，降低速度。最终传动比在实际驾驶中对提高油耗的影响，以及主观上可感知的纵向动力学，迄今为止几乎没有被考虑过。

Influence of the final drive ratio on the consumption of passenger cars under real driving conditions

The predetermined gear shift points in the type approval test for the European Union (NEDC - New European Driving Cycle) influence the technical design of today's vehicles with manual transmission significantly. Most manufacturers select a long total gear ratio to achieve fuel savings by down speeding. The effects of the final drive ratio on improving fuel consumption in real customer driving, and subjectively perceivable longitudinal dynamics have hardly been considered so far.
