Abstract: In a method for a torque-based control of an internal combustion engine wherein from an input value representing a desired engine power output a desired torque value is calculated, then the desired torque value is converted using a performance graph while taking another value into consideration to a first power output determining signal, which is then corrected by way of a relative efficiency and a power determining signal for controlling the drive torque is determined. The additional value corresponds to a relative friction moment, which is calculated from an actual deviation of the state of the engine from a standard state in which the relative friction moment is zero.

Abstract: In a method of controlling an internal combustion engine wherein an injection begin is calculated depending at least on an actual engine speed and the injection begin is corrected, the injection begin correction is calculated from a deviation of a desired air mass flow from an actual air mass flow.

Abstract: A method for the torque-oriented control of an internal combustion engine in which a set torque is computed from an input variable that represents the desired power, and the set torque is limited to an air mass-dependent maximum torque.

Abstract: This invention relates to a method and apparatus for recognizing the impact time of a solenoid valve armature during de-energizing. In order to obtain a detectable impact signal of the armature, a measuring current is provided in the magnet coil during the armature's downward movement to generate a magnetic measuring field. When this magnetic measuring field is changed due to the armature movement, an induction voltage is generated, which is monitored to detect the time of impact of the armature.
