    Abstract: A method for controlling an internal combustion engine system so as to avoid turbo surge and/or shorten power cut off during gearshift is provided. The internal combustion engine system includes: an internal combustion engine and a gearbox operatively connected to the internal combustion engine; a turbocharging arrangement configured to provide a boost pressure of air fed to the internal combustion engine; and a control system configured to control operation of the internal combustion engine system, the method comprising: providing information about a point of time for initiating an upcoming gearshift, a target engine speed after the upcoming gearshift, iii) a target engine torque after the upcoming gearshift, and current operation conditions of the internal combustion engine system; determining, based on said information and before the upcoming gearshift is initiated, whether there is a risk of having turbo surge during the upcoming gearshift; and, if such a risk is determined, lowering the boost pressure before initiating the upcoming gearshift.

    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: According to the present invention, there is provided a control device for an internal combustion engine which includes a motor driving a WG valve (waste gate valve), and in which a target opening degree of the WG valve is set in accordance with a running state of an internal combustion engine and a valve opening degree of the WG valve is controlled by controlling electrification of the motor. While the internal combustion engine is starting or is running with the target opening degree set to a fully-closed opening degree, an electrification duty ratio of the motor is controlled such that the electrification duty ratio meets a predetermined value allowing the WG valve to be pressed to a fully-closed position, and electrification of the motor stops after the WG valve is driven to the fully-closed position while the internal combustion engine is in a stop state.
