    摘要: The method for controlling operation of a vehicle having at least two possible operating modes includes calculating and/or determining the operating variables and/or control variables of at least one active one of at least two possible operating modes in a first continually repeated predetermined time interval and calculating and/or determining the operating variables and/or control variables of at least one inactive one of the at least two possible operating modes in at least one other continually repeated predetermined time interval. The first predetermined time interval is shorter than any of the one or more other predetermined time interval(s). A device for performing the method is also described.

    摘要: A method for determining a gas charge of an internal combustion engine having an intake manifold. The intake manifold has a gas mixture, which is a fresh air/fuel mixture and an exhaust gas, and further has a gas mass flow from the intake manifold and an intake manifold pressure. The method includes the steps of determining a partial pressure of the fresh air/fuel mixture in the gas mass flow by setting up a mass balance for a fresh air/fuel mixture mass flow, determining a partial pressure of the exhaust gas in the gas mass flow by setting up a mass balance for an exhaust gas mass flow, and determining a gas mass flow via a throttle based on a function that depends on a temperature compensation factor, a pressure compensation factor and a factor depending on a ratio of a pressure downstream of the throttle to a pressure upstream of the throttle. The pressure downstream of the throttle corresponds to the intake manifold pressure.
