主权项

1. A vehicle, comprising:
an internal combustion engine having a crankcase, a crankcase ventilation device, which has at least one oil separating device and an oil return that feeds separated oil back to the crankcase, a conveying device for driving a fluid other than a blow-by gas, wherein the conveying device is also configured to drive the blow-by gas in the crankcase ventilation device, an intake line of the crankcase ventilation device for communicating the blow-by gas and connecting the crankcase to an intake side of the conveying device, wherein the intake line includes the oil separating device and is connected downstream the oil separating device to a fresh air system of the internal combustion engine, and a control device for actuating a control member in response to a current pressure in fresh air in a region of the connection of the fresh air system to the intake line to control the connection between the intake line and the conveying device, wherein the control device actuates the control member to deactivate the driving of the blow-by gas via the conveying device in response to the current pressure exceeding a pressure threshold.
