A control device for an internal combustion engine includes an intake air amount controller and a variable valve controller. The intake air amount controller includes an exhaust manifold pressure calculator, an engine intake air amount calculator, a volumetric efficiency correction coefficient calculator, a cylinder intake air amount calculator, an exhaust gas flow rate calculator, and a cylinder intake air amount controller. The volumetric efficiency correction coefficient calculator calculates a volumetric efficiency correction coefficient based on a pressure ratio between an intake manifold pressure and an exhaust manifold pressure, a rotational speed of the internal combustion engine, and an actuation state of at least one of an intake valve and an exhaust valve.

A method of generating vehicle control data is provided. The method is executed using a processor and a storage device and includes: storing first data that prescribe a relationship between a state of a vehicle and an action variable that indicates an action related to an operation of an electronic device; acquiring a detection value from a sensor that detects the state of the vehicle; operating the electronic device; calculating a reward, on the basis of the acquired detection value; in a case where a predetermined condition is met, updating the first data using, as inputs to update mapping determined in advance, the state of the vehicle, a value of the action variable, and the reward; and in a case where the state of the vehicle does not meet the predetermined condition, obtaining second data by adapting the relationship between the state of the vehicle and the action variable.

A control module includes a dynamic target selection module configured to receive an intake manifold pressure setpoint and a measured intake manifold pressure, select between the intake manifold pressure setpoint and the measured intake manifold pressure, and output a selected intake manifold pressure setpoint based on the selection. A multivariable control module is configured to receive at least one target setpoint that is based on the selected intake manifold pressure setpoint and control operation of an air charging system of a vehicle based on the at least one target setpoint.

An internal combustion engine with a regulating device, whereby a fuel-air mixture is burned in the internal combustion engine with a combustion air ratio controllable by the regulating device, whereby the regulating device comprises an emission control loop, which is designed to control the charge-air pressure as a substitute variable for the NOx emission by the actuators influencing the charge-air pressure via a functional relationship, such that, for each target power or actual power of the internal combustion engine, a charge-air pressure target value can be set, and whereby the internal combustion engine further comprises a variable valve train, by means of which an operating characteristic of at least one inlet valve can be varied, whereby the functional relationship takes into account the influence of an adjustment of the operating characteristic of the at least one inlet valve.

A method for a combustion motor that is initially used in a full Miller cycle or full Atkinson cycle that is advantageous with regard to efficiency. In full operation, a switchover to a partial operation takes place, wherein the intake valves associated with the combustion chambers that are to continue to be operated are switched over to actuation in accordance with a second valve lifting curve in order to achieve a switchover that is as torque-neutral as possible and is optimal with regard to efficiency. The closing time of the intake valve brought about by this second valve lifting curve is designed with respect to maximum volumetric efficiency.

A method for adaptation of a detected camshaft position of a camshaft in an internal combustion engine with: Detection of an ACTUAL gas signal in a gas space that is associated with the camshaft and is associated with a detected camshaft position; Processing of the gas signal to produce an ACTUAL gas criterion; Modeling of multiple simulated gas criteria, each of which is associated with a target camshaft position; Determination of a simulated gas criterion with the least deviation from the ACTUAL gas criterion; Determination of an ACTUAL camshaft position that corresponds to the simulated gas criterion with the least deviation from the ACTUAL gas criterion; Determination of a camshaft position correction value from the difference between the ACTUAL camshaft position determined and the detected camshaft position; Determination of corrected camshaft positions by correcting the detected camshaft positions with the camshaft position correction value.

A multi-injection process includes performing intake synchronized injection in which fuel is injected in synchronism with an open valve period of an intake valve, and an intake asynchronous injection in which fuel is injected at a more advanced timing than during intake synchronized injection. A single-injection process includes injecting a required injection amount of fuel by intake asynchronous injection. An operating process includes operating a port injection valve for injecting fuel into an intake passageway. A selection process includes selecting the single-injection process if the temperature of an intake system of an internal combustion engine is not lower than a prescribed temperature, and selecting the multi-injection process if the temperature of the intake system is less than the prescribed temperature.

The present invention relates to a method for controlling an internal combustion engine arrangement (100). The internal combustion engine arrangement (100) comprises a combustion cylinder (102) and an inlet valve (106) arranged to be positioned in a closed position at a distance before a piston (104) reaches a bottom dead center during normal operation. The inlet valve is further controllable to be arranged in the open position until the piston reaches the bottom dead center if a required volumetric efficiency of the combustion cylinder is higher than a volumetric efficiency during normal operation.

A system and method for improving the functioning of a turbocharged diesel engine equipped with a cylinder deactivation system includes detecting when the turbocharged diesel engine is at risk of compressor surge, and then delaying the implementation of the cylinder deactivation. The delay may be a set period of time, or it may be determined by performing a set of instructions effective for estimating changes in intake manifold pressures over time if cylinders are deactivated, and then comparing the intake manifold pressure estimates to acceptable intake manifold pressure information. A formula for performing the required estimates is provided.
