A method for adjusting a fuel mass to be injected into an internal combustion engine. The internal combustion engine including an intake tract, at least one cylinder, and an exhaust tract. In the method, an air mass introduced into the internal combustion engine is ascertained and a fuel mass to be injected into the internal combustion engine is determined. An air-fuel ratio in the exhaust tract of the internal combustion engine is determined which is adjusted in time. Based on the time-adjusted air-fuel ratio and the calculated fuel mass to be injected, a first wall film fuel mass is calculated and the fuel mass to be injected is adjusted based on the first wall film fuel mass.

Method for adjusting a fuel mass to be injected

A control system for a motor vehicle, for outputting a controlled variable, with the aid of which a directly controlled variable of a motor vehicle is adjustable via suitable control operations, in order to adapt the directly controlled variable to a reference variable of the control system. The control system includes a controller, which is configured to output a first output variable on the basis of the directly controlled variable of the motor vehicle, and on the basis of the reference variable of the control system. The control system further includes a predictive model, which may be trained to output a second output variable that reflects a deviation of a driving behavior of a driver of the motor vehicle from the first output variable of the controller. The controlled variable of the control system encompasses an addition of the first output variable and the second output variable.

Control system for a motor vehicle and method for adapting the control system

A computer-implemented method for using machine learning to determine control parameters for a control system, in particular of a motor vehicle, in particular for controlling a driving operation of the motor vehicle. The method includes: providing a set of travel trajectories; deriving reward functions from the travel trajectories, using an inverse reinforcement learning method; deriving driver type-specific clusters based on the reward functions; determining control parameters for a particular driver type-specific cluster.

A method for the operation of a particulate filter in an exhaust aftertreatment system of a combustion engine () with the following steps: set up () a pressure difference model, which models a measured pressure difference (&#x394;p) which drops across the particulate filter () as a function () of a volume flow ({dot over (V)}) through the particulate filter () with an offset value (a, C); measure () multiple measurement values () for the pressure difference (&#x394;p) at different volume flows ({dot over (V)}) and solve () the pressure difference model as a function of the pressure difference (&#x394;p), whereby the offset value (a, C) is also determined.

A method for operating an internal combustion engine having a camshaft phase adjuster, including: providing a nonlinear final control element model, which indicates via a functional relationship an angular velocity of a relative adjustment of the camshaft phase adjuster as a function of an actuator correcting variable for the control of the camshaft phase adjuster; carrying out a control based on a deviation between a predefined camshaft angle adjustment setpoint value, and a camshaft angle adjustment actual value, to obtain as a control output a setpoint positioning rate of the camshaft phase adjuster; calculating the actuator correcting variable as a function of the setpoint positioning rate using an inverted final control element model; applying a predefined correction variable to the actuator correcting variable; controlling the camshaft phase adjuster using the actuator correcting variable to which the correction variable has been applied, to operate the internal combustion engine.

A method for operating a supercharging device for an internal combustion engine, the supercharging device being supported as an exhaust gas-driven supercharging device by an electric motor-driven supercharger drive or being operated exclusively by the electric motor-driven supercharger drive, the electric motor-driven supercharger drive being operated as a function of a setpoint actuating torque, the setpoint actuating torque being determined as a function of a pilot control torque from a pilot control unit and a control actuating torque from a rotational speed control unit.
