Abstract: A device is directly or indirectly connectable to a patient for determining a volume related to the lungs of the patient. The device has an inspiration part through which a breathing gas passes towards the patient, and an expiration part through which the breathing gas passes away from the patient. The inspiration part has a mouthpiece for introducing a change of the gas composition in the breathing gas. The device implements a method for determining the volume with a detector being arranged in the expiration part that measures a measuring parameter which is dependent on the change in the gas composition, and with a calculation unit connected to the detector unit that determines the variation in the measuring parameter, and determines the volume from the determined variation.

Abstract: When controlling an engine provided with Variable Turbine Geometry (VTG), the VTG is closed to a maximally acceptable closed position without endangering the VTG when performing an up-shift. The VTG is kept in such a position during the gear shift which, allows for a quick retardation of the engine speed.

Abstract: When controlling an engine having a Variable Turbine Geometry (VTG) the VTG is closed some predicted time period before an up-gear shift is performed. This is advantageous because when the gear shift begins the engine breaking is already maximized and full engine brake can be obtained during the entire gear shift operation.

Abstract: In a method and a system for controlling the Variable Turbine Geometry (VTG) of a combustion engine during up-gear shift, the VTG is opened based on a prediction when exhaust gas pressure is stabilized. During up-gear shift the VTG is closed to a closed position (301) to build an exhaust gas pressure and reduce engine speed, and a parameter from which the engine acceleration can be deduced is recorded. The VTG is determined to be opened to an open positioning response to the recorded parameter and a target engine speed of the up-gear shift (303), and the VTG is opened at a time corresponding to said determination to reduce the exhaust gas pressure (305). Hereby the up-gear shift can be made in a short time and at smooth operational conditions.

Abstract: A method for executing a gear shift step in a motor vehicle (100; 110) having an engine (220) and an automated manual transmission incorporating a clutch (230) and a gearbox (240), the method includes the steps, during a gear shift procedure, controlling a torque (Tc) in the clutch (230) to enable a gear shift step to take place before a target speed (rpm*) of the engine (220) is reached; and, when the clutch (230) has stopped sliding, of controlling a torque (Te) of the engine (220) on the basis of the torque (Tc) in the clutch (230). A computer program product includes program code (P) for a computer (200; 210) for executing a method according to the invention. Also disclosed is a device for executing the gear shift step in a motor vehicle (100; 110) having an engine (220) and an automated manual transmission incorporating a clutch (230) and a gearbox (240), and a motor vehicle equipped with the device is disclosed.
