A method of controlling an internal combustion engine is provided, in which at least two operating states are differentiated, at least one operating variable of the engine being controlled, a setpoint torque being predetermined on the basis of the optimum operating point for the respective operating state and on the basis of the position of a throttle valve operated by the driver, and the value of at least one operating variable to be output being determined from the setpoint torque. A cylinder-individual firing angle retardation value is predetermined by a knock control system, so that the cylinder-individual firing angle retardation value is taken into account directly in calculating the setpoint torque.

Method of controlling an internal combustion engine

In a method of controlling an internal combustion engine, at least one operating variable is controlled, a pre-control ignition timing efficiency is formed as a function of operating parameters of the engine and/or external intervention measures, and the pre-control ignition timing efficiency determines the setpoint values of the at least one operating variable. In a transition from a first operating state to a second operating state, the pre-control ignition timing efficiency is varied by a transition function.

A method and an arrangement for controlling the drive unit of a vehicle are suggested. In a first step, input quantities, which are independent of the drive unit, are applied to form a first input quantity. In a second step, a second input quantity is formed from at least this first input quantity and at least one engine-specific input quantity, the second input quantity influencing at least an actuating quantity of the drive unit. In addition, an interface is described between the engine-independent part and the engine-specific part of the engine control.

Method and device for controlling the drive unit of a vehicle

A method and a device for controlling the drive unit of a vehicle are provided, in which, in addition to the selection variable for an output variable of the drive unit, another setpoint variable representing the required dynamic setting of the output variable is preselected. The manipulated variable of the drive unit to be influenced is selected on the basis of the selection variable and the additional setpoint variable.

The invention is directed to a method and an arrangement for the rpm control of a drive unit. A control is provided having at least two components. At the start of the drive unit, these two components are activated one after the other.

The invention is directed to a method and arrangement for checking the operability of a vessel. Pressure is introduced into the vessel utilizing a pressure source having operating variables which vary during operation of the pressure source. These operating variables are detected while the pressure is introduced into the vessel and a conclusion as to a presence of a leak in the vessel is drawn from the operating variables. By utilizing the operating variables, a statement as precise as possible is provided as to the presence of the leak with as little additional equipment as possible.
