    Abstract: A method for propulsion of a vehicle (100), the vehicle (100) has a combustion engine (101) and a gearbox (103) that can be adjusted to a number of gear ratios for the transfer of force between the combustion engine (101) and at least one driving wheel (113, 114). The engine (101) combustion chamber has at least one inlet for supply of combustion gas and at least one outlet for evacuation of exhaust gas from the combustion chamber, a turbocharger unit (203) for pressurizing the combustion gas in the combustion chamber. During a change of gear from a first higher to a second lower gear ratio, wherein the rate of revolution of the combustion engine (101) is reduced from a first rate to a second rate, increasing the pressure (Put) at the chamber outlet (202) at least through the use of the turbocharger unit for constriction of the exhaust gas flow to reduce the pressure (Pin) at the combustion gas through the opening of a first valve (221) and, when the rate of revolution (n) of the combustion engine (101) has at least partially fallen towards the second rate of revolution (n2), controlling the turbocharger unit (203) such that the combustion gas pressure (Pin) is increased. Also a system and a vehicle are disclosed.

    Abstract: A method for propulsion of a vehicle (100): The vehicle (100) includes a combustion engine (101), and a gearbox (103) that can be adjusted to a number of gear ratios for transfer of force between the combustion engine (101) and at least one driving wheel (113, 114), at least one combustion chamber with at least one inlet for the supply of combustion gas and at least one outlet for the evacuation of an exhaust gas flow that has resulted from combustion in the combustion chambers and a turbocharger unit (203) for pressurizing the combustion gas. In the method, during the change of gear from a first higher gear ratio to a second lower gear ratio, the rate of revolution of the combustion engine (101) is reduced, to control the turbocharger unit such that the pressure of the combustion gas is reduced, to increase the pressure at the outlet by constriction of the exhaust gas flow, and when the rate of revolution of the combustion engine (101) has at least partially fallen towards a second rate of revolution, to control the turbocharger unit such that the combustion gas pressure is increased. Also a system and a vehicle including the system.
