Abstract: A method for controlling operation of a vehicle. The method includes: providing information on geographical position of a first (starting) location and a second (destination) location and on length and topography for at least one possible route to be taken by the vehicle from the first location to the second location; calculating, based on vehicle conditions and on length and topography for the at least one possible route, a plan for how to control the powertrain system to achieve an energy efficient performance of the powertrain system if driving the vehicle along said at least one possible route. The method further includes: setting the vehicle in a non-drive off mode that prevents the vehicle from driving off from the first location, and setting the vehicle in a normal operation mode that allows drive off from the first location when calculating the plan has been carried out.

Abstract: A device and a method for controlling vehicle speed in a vehicle equipped with brake cruise control when the vehicle is travelling downhill are provided. The method involves driving a vehicle downhill with the brake set speed set to a first brake set speed; detecting a current vehicle speed; automatically applying a brake torque using at least an auxiliary brake to maintain the first brake set speed; and detecting a manual application of a vehicle service brake, in order to decrease vehicle speed. If a control unit detects that the driver is applying the service brake, then the control unit is automatically arranged to set the brake set speed to a second brake set speed that is lower than the first brake set speed; and to apply a brake torque using at least the auxiliary brake if a detected current vehicle speed exceeds the second brake set speed.
