Abstract
A method in a control arrangement of a vehicle and a control arrangement for a vehicle for downshifting gears in an uphill slope are presented. The method comprises, when the vehicle is travelling in an uphill slope using an initial gear of the vehicle's automated manual transmission gearbox: simulating at least one speed profile for a downshift to, and a usage of, at least one gear; determining that a minimal speed of each one of the at least one simulated speed profile has a value indicating that the actual speed of the vehicle will be less than or equal to zero in the uphill slope; opening a clutch before is reduced to a value less than zero; activating at least one vehicle brake; shifting vehicle's automated manual transmission gearbox to a start gear; closing the clutch; and deactivating the at least one vehicle brake.
