    Abstract: A method for degradation diagnosis of an electrochemical cell, comprising: determining a first open circuit potential, relative to a preselected potential scale, for a positive electrode and determining a second open circuit potential, relative to the preselected potential scale, for a negative electrode; obtaining a first charge value and a second charge value by comparing the determined first and second open circuit potentials to respective reference curves of open circuit potential, relative to the preselected potential scale, as a function of charge for the corresponding electrode; arranging the first and the second reference curves on a common charge scale so that the obtained first charge value and the obtained second charge value are equal on said common charge scale; and based on the first and second reference curves, determining remaining capacity as the difference in charge between a first predefined potential limit and a second predefined potential limit.

    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 vehicle driving assembly is disclosed comprising an axle beam and a propulsion unit. The axle beam comprises a mounting section comprising a cavity with an opening facing in a direction perpendicular to an axial direction of the axle beam. The cavity accommodates a portion of the propulsion unit protruding into the cavity via the opening. The propulsion unit is attached to the mounting section of the axle beam with a number of fastening elements arranged at a first mounting interface and at a second mounting interface arranged at a respective side of an axial plane extending through a respective rotation axis of at least two opposing ground engaging wheels of the axle beam. The present disclosure further relates to a vehicle comprising a vehicle driving assembly.

    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.
