Abstract: The disclosed subject matter relates to a method for determining a starting sequence for a fuel cell arrangement including a plurality of fuel cell systems. The starting sequence includes the following information for each fuel cell system in the fuel cell arrangement: whether or not the fuel cell system should be started and, if the fuel cell system should be started, the starting time for the fuel cell system, said starting sequence being determined using the following as input: a power and/or energy need required from the fuel cell arrangement over an upcoming time range; a shutdown duration time of each fuel cell system, indicative of the time elapsed since the fuel cell system was lastly shutdown, and a predetermined degradation characteristic of each fuel cell system as a function of shutdown duration time.

Abstract: A computer-implemented method for clutch start control of an internal combustion engine, ICE, in a vehicle is described. When the vehicle is travelling on a road with the ICE being shut off, topographic data representative of the topography of an upcoming road segment is acquired. A driving scenario for at least a part of the upcoming road segment is predicted based on the acquired topographic data. A gear is selected based on the predicted driving scenario. The ICE is started on the selected gear before or when the vehicle reaches said part of the road segment.

Abstract: A computer-implemented method of brake management in an electric or hybrid electric heavy-duty vehicle that has batteries which are configured to absorb energy from regenerative braking is provided. Topographic data containing information about an upcoming downhill slope is obtained. A state of charge target (SOC target) below 100% for said batteries is determined.

The determined total brake power is in the form of at least one of regenerative braking, auxiliary braking and service braking of the heavy-duty vehicle.

The method uses topographic data in order to provide predictive control of the vehicle driveline, where the driveline comprises a first driving mode and a second driving mode, where the vehicle is driving to a predetermined destination. The method includes receiving topographic data for the route to the predetermined destination, determining a number of predictive parameters for the route, where, in the first driving mode, the vehicle driveline is controlled in an eco-mode in order to provide the lowest possible energy consumption to the predetermined destination, and where, in the second driving mode, the vehicle driveline is controlled in order for the vehicle to arrive at the predetermined destination at a predetermined time.
