The invention relates to a computer-implemented method of controlling the cabin climate in a vehicle travelling on a road. A requested temperature value of a desired temperature for at least one part of the cabin is detected. An allowable temperature deviation from the requested temperature value is determined. Topographic data representative of the topography of an upcoming road segment is acquired. A flow creating device of an air-conditioning system of the vehicle is controlled based on the acquired topographic data so as to maintain the temperature within the allowable deviation. The invention also relates to a computer program, to a computer readable medium, to a control unit and to a vehicle.

A computer system comprising processing circuitry configured to: determine predicted vehicle operational information for a vehicle including at least predicted travel route for a vehicle, a predicted shutdown of a combustion engine of the vehicle along the predicted travel route, and a predicted subsequent re-start of the combustion engine; determine the topography of the predicted travel route subsequent to the predicted re-start of the combustion engine; determine a set ammonia storage level threshold of a selective catalytic reduction, SCR, catalyst arranged in an exhaust after treatment system to the combustion engine in response to the topography of the predicted travel route subsequent to the predicted combustion engine re-start; and control an injector of the exhaust after treatment system to inject a predetermined amount of reductant achieving the set ammonia storage level threshold prior to shutdown of the combustion engine.

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.

A calibration method for at least one propulsion unit of a marine vessel, the at least one propulsion unit being arranged to provide a propulsive force to the vessel, the at least one propulsion unit being adjustable so as to change a respective steering angle of the at least one propulsion unit in relation to a hull of the vessel. The method includes controlling the at least one propulsion unit so as to provide at least one acceleration sequence, wherein the vessel is accelerated stepwise or continuously in each acceleration sequence, adjusting, continuously or repeatedly, during the acceleration sequence, the steering angle of the at least one propulsion unit, to keep the path of the vessel straight during the acceleration sequence, registering, during the acceleration sequence, a plurality of values of the respective steering angle of the at least one propulsion unit, and determining, based at least partly on the registered steering angle values, a respective reference steering angle of the at least one propulsion unit, which reference steering angle minimizes a deviation of an actual course over ground of the vessel from a desired course over ground of the vessel.
