Abstract: The invention relates to a method and a control arrangement for controlling a speed of a vehicle in an upcoming road section comprising a road crest. The method comprises: determining a speed reduction to be performed before reaching the road crest based on at least a gradient of a downhill slope following the road crest; determining whether the upcoming road section has a single lane or multiple lanes; controlling the speed of the vehicle in the upcoming road section based on the speed reduction and based on whether the upcoming road section has a single lane or multiple lanes, wherein the speed reduction is limited when the upcoming road section has a single lane compared to when the upcoming road section has multiple lanes. In some embodiments, the speed reduction of the vehicle is limited in situations when there is a risk of queues building up behind the vehicle.

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.
