    摘要: A method for operating a hybrid drive system which includes ascertaining an overall cost function that takes into account the cost function, which is a function of the operating point, for minimizing an energy usage of the hybrid drive system, and that takes into account one or more partial cost functions, which are a function of the operating point, which are each assigned to a requested special function; determining an optimized operating point of the hybrid drive system corresponding to an optimization according to the ascertained overall cost function; operating of the hybrid drive system at the operating point; and executing of those of the requested special functions for which the determined operating point is within an operating range assigned to the respective special function.

    摘要: A method for determining a nitrogen oxide emission and an ammonia emission in the combustion exhaust gas of an engine system having an exhaust-gas-guided internal combustion engine using an output-side nitrogen oxide sensor having a cross-sensitivity to ammonia. The method including: detecting a measurement signal of the nitrogen oxide sensor; ascertaining a partial conversion indication for each of multiple catalytic converter segments arranged in series in the combustion exhaust gas depending on local operating conditions with the aid of a provided conversion model that maps a local operating condition on the partial conversion indication; determining a conversion indication from the multiple partial conversion indications; and ascertaining a nitrogen oxide emission and an ammonia emission depending on the measurement signal and the conversion indication.

    摘要: In a method for operating a motor vehicle having an internal combustion engine, pre-heating measures (7) for reaching operating temperatures for components of the exhaust-gas post-treatment system and/or for a lambda probe of the motor vehicle are provided prior to the departure (10) of the motor vehicle. The activation of a transducer (1) by a driver of the motor vehicle for explicitly announcing an impending departure of the motor vehicle is provided as the trigger for the pre-heating measures (7), in particular for avoiding an unnecessary initiation of pre-heating measures.

    摘要: A method (200) for operating an exhaust gas system (120) that includes a first catalytic converter (122) and at least one second catalytic converter (124), which are both arranged downstream from an internal combustion engine (110) The internal combustion engine (110) is controlled to generate a rich exhaust gas having a first rich gas portion, (220) a fill level of the second catalytic converter (124) is ascertained with respect to at least one lean gas component that is storable in the second catalytic converter and, if the ascertained fill level drops below (230) a minimum fill level, (240) the internal combustion engine (110) is controlled to generate a lean exhaust gas. The internal combustion engine (110) is then controlled to generate a rich exhaust gas having a second rich gas portion, and subsequently controlled (210) to generate the rich exhaust gas having the first rich gas portion.
