Abstract: A method and a device for controlling a fuel-operated internal combustion engine of a motor vehicle having a tank venting system associated with a fuel tank and having at least two operating states, in which the internal combustion engine is shut off automatically according to a shut-off strategy. The shut-off strategy takes into account the instantaneous operating state of the tank venting system.

Abstract: A method and a device for operating a drive unit, a computer program product having program code and a computer program which allow for an adaptation of a torque loss even outside of an idling operating state of the drive unit. In this instance, the losses of an output variable of the drive unit, in particular of a torque, are adapted. The losses are adapted during a shutdown of the drive unit.

Abstract: The invention relates to a procedure to heat up or keep warm an exhaust gas emission control assembly of a vehicle with a drive train containing one transmission. The drive train is powered by an internal combustion engine and at least one second drive unit. It is proposed that also in an operating state, which lies outside of the idle speed, a rotational speed or a torque of the internal combustion engine deviating from values for the engine rotational speed and the torque is set, which would exist during an identical driving condition without the heating-up or keeping warm of the exhaust gas emission control assembly.

Abstract: A method and a device for operating a drive unit, in particular of a vehicle, are provided, which allow for an adaptation of losses of an output variable of the drive unit, in particular of a torque, which is precise and which restricts as little as possible a request to shut down the drive unit. For this purpose, the losses are adapted during at least one operating phase, in particular an idling operating phase, of the drive unit. With the conclusion of a successful adaptation, a shutdown of the drive unit is enabled.
