Abstract:
1. A method for controlling a fuel-operated internal combustion engine of a motor vehicle, comprising: 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, wherein the shut-off strategy takes into account the instantaneous operating state of the tank venting system, wherein at least one first state of the operating states represents a correct state of the tank venting system and at least one second state represents a defective state of the tank venting system; wherein the shut-off strategy is configured in such a way that in the case of a tank venting system recognized as defective, the internal combustion engine is not shut off or is shut off with a delay; and wherein the tank venting system is recognized as defective at least when the tank venting valve cannot be closed and/or its controller does not allow the valve to be closed.
