Abstract: Disclosed are a control arrangement and method for controlling wheel slip in a vehicle comprising a plurality of mechanically independent powertrains. The plurality of mechanically independent powertrains comprises, as seen in a driving direction of the vehicle, a leading powertrain, and at least one trailing powertrain. The method comprises monitoring of estimated road friction for the leading powertrain and estimated road friction for the at least one trailing powertrain. When a derivative of a difference between the estimated road friction for the leading powertrain and the estimated road friction for the at least one trailing powertrain is above a threshold and the estimated road friction for the leading powertrain is greater than the estimated road friction for the at least one trailing powertrain, the method comprises reducing a maximum allowable wheel slip for the leading powertrain and controlling the leading powertrain in dependence of the reduced maximum allowable wheel slip.

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. The method comprises simulating a vehicle speed profile for an upcoming road section if braking at a pre-identified power level would currently be requested, thereby obtaining a predicted maximum vehicle speed and a predicted time until a vehicle speed equal to or within a pre-selected interval 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 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.

Abstract: A method of outputting a notification in a driver environment of a vehicle is disclosed. The method comprises obtaining topographic data representative of the topography of an upcoming road segment, identifying an upcoming downhill slope in the upcoming road segment, obtaining, based on the topographic data, a speed estimate representative of a maximum allowable speed of the vehicle upon reaching the upcoming downhill slope for keeping the speed of the vehicle below a threshold speed in the upcoming downhill slope while using a predetermined braking amount of wheel brakes of the vehicle, and outputting a notification indicating the speed estimate in the driver environment before the vehicle reaches the upcoming downhill slope. The present disclosure further relates to a computer program, a computer-readable medium, a control arrangement, and a vehicle.

Abstract: A method is provided for controlling operation of a vehicle having at least one leading wheel axle and at least one trailing wheel axle. The method monitors a wheel slip of the wheels arranged at the at least one leading wheel axle and controls a wheel torque of the wheels arranged at the at least one trailing wheel axle based on: (i) the monitored wheel slip, (ii) a speed of the vehicle relative to the surface, and the distance between the at least one leading wheel axle and the at least one trailing wheel axle.

Abstract: A method of controlling operation of a vehicle is disclosed, wherein the method comprises the steps of monitoring a wheel slip of the wheels arranged at at least one leading wheel axle, and controlling a wheel torque of the wheels arranged at at least one trailing wheel axle based on the monitored wheel slip, a speed of the vehicle relative to the surface, and the distance/distances between the at least one leading wheel axle and the at least one trailing wheel axle. The present disclosure further relates to a computer program product, a computer readable medium, a control arrangement, and a vehicle.

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.
