Abstract
A control device and a method for controlling traveling speed of a vehicle for the purpose of maintaining a vehicle speed equal to or lower than a pre-set downhill speed (vdh-set). The method comprises simulating a vehicle speed profile for an upcoming road section if braking at a pre-identified power level (P1, P2, P3) would currently be requested, thereby obtaining a predicted maximum vehicle speed (vP1,max, vP2,max, vP3,max) and a predicted time until a vehicle speed equal to or within a pre-selected interval (Idh) of the pre-set downhill speed is reached. The method further comprises, if the predicted maximum vehicle speed is equal to or below the pre-set downhill speed (vdh-set) and the predicted time is below a preselected threshold time limit, requesting braking at the pre-identified power level or at an adjusted power level.
