Abstract: A method is provided for controlling a speed of a vehicle, using a Pulse and Glide (PnG) operation, whereby the speed of the vehicle is controlled about a reference speed. The PnG operation comprises a pulse-phase during which the speed of the vehicle is increased to a first speed, higher than the reference speed, followed by a glide-phase during which the speed of the vehicle is allowed to decrease to a second speed, lower than the reference speed. The method is performed when the PnG operation is to be carried out and when a speed increase to an increased speed, higher than the reference speed, is to be commenced during the PnG operation. The method comprises adjusting the PnG operation such that the speed increase to the increased speed, is carried out by accelerating the vehicle immediately following a speed decrease in the glide-phase to at least the second speed.

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.
