Abstract: A method for performing an on-board diagnostic function in a motor vehicle including at least one drive system, at least one operating element and at least one control unit with a processor, a control module and an on-board diagnostic function module. The method includes the steps of: activating an on-board diagnostic function in the on-board diagnostic function module; supplying a first signal profile (S1) of an operating value (CV) of the operating element to an analysis module; the analysis module analyzing the first signal profile (S1) of the operating value (CV); activating a filtering module in the event of a positive analysis result; and the filtering module filtering the first signal profile (S1) of the operating value (CV) with selected damping parameters (DP) upon activation of the filtering module in order to obtain a filtered second signal profile (S2) of the operating element.

Abstract: A drive train arrangement for a motor vehicle includes at least one drive device, a start-up element arrangement, a gear drive arrangement, at least one driveshaft configured to drive drive wheels, an electronic operator control member configured to be operated, a torque control member, and a controller. The controller is configured to store torque regions for a change in load and to transmit a torque default value to the torque control member depending on an actuation of the electronic operator control member. The stored torque regions are zero transition regions with a zero transition starting point and a zero transition end point for covering all zero-load clearance regions. The controller is configured to adapt at least one respective zero transition region of at least one respective stored torque region.

Abstract: A method for controlling an engine in a motor vehicle includes determining a theoretical inertia of a drivetrain during a change of an operating mode of the engine, detecting an actual inertia in the drivetrain during the change of the operating mode, and increasing a rotational speed of the engine in response to detecting the actual inertia. The method further includes detecting an inertia overcome, determining a difference between the theoretical inertia and the inertia overcome, and reducing the rotational speed of the engine if the difference becomes less than a threshold value.

Abstract: A method for controlling a setpoint charging pressure for a turbocharger includes determining a charge-based setpoint charging pressure on the basis of a charge of the internal combustion engine, sampling an actual charging pressure, determining a carried-along actual charging pressure on the basis of the actual charging pressure, determining an offset on the basis of the charge-based setpoint charging pressure, and adjusting, by open-loop control, the setpoint charging pressure to the charge-based setpoint charging pressure by a first-order timing element if the carried-along actual charging pressure exceeds a first value which is lower than the charge-based setpoint charging pressure by the offset.

Abstract: A method for controlling an internal combustion engine of a motor vehicle includes detecting a driving situation of the motor vehicle and determining a setpoint torque (M2) based on the detected driving situation. An expected driving situation of the motor vehicle is ascertained and a torque reserve is determined based on the ascertained expected driving situation of the motor vehicle. The setpoint torque (M2) is set by setting an ignition angle of the internal combustion engine, and the torque reserve (MR) is set by setting a pressure of a gas mixture that flows into the internal combustion engine.

Abstract: A method for operating a drivetrain of a motor vehicle, the drivetrain having a drive unit with an internal combustion engine and with at least one turbocharger, a driver demand torque being determined as a function of a present accelerator pedal actuation (PI), a drive unit torque (MNEW) which is dependent on the driver demand torque (MDD) provided by the drive unit via a load shock damping facility such that the drive unit torque (MNEW) is built up as a function of the driver demand torque via load filter gradients of the load shock damping facility, and wherein in the case of a relatively high driver demand torque, to ensure a comfortable and dynamic build-up of the drive unit torque using the or each turbocharger, a nominal value (MNOM,2) for an air-based torque is increased more quickly to a maximum value than a nominal value (MNOM,1) for an ignition-based torque.
