| 摘要 |
The present invention concerns a method related to the propulsion of a vehicle (100), wherein a transmission (103) can be set to a plurality of gear ratios, and wherein the propulsion of said vehicle (100) is affected by a running resistance (F). The method comprises, when said vehicle (100) is driven with said transmission (103) set to a first gear ratio : a determination as to whether a supply of a quantity of fuel to said combustion engine (101) has decreased to a first level due to decreased running resistance (F), and setting said transmission to a second gear ratio that is lower compared to said first gear ratio within a first time from when said supplied fuel to said combustion engine (101) has decreased to said first level. |
