Abstract: A method for controlling an internal combustion engine having a common rail system together with individual accumulators. A rotational speed-control deviation (dn) is determined from a target rotational speed (nSL) that represents the set point for an outer control loop to control the rotational speed, as well as from an actual rotational speed (nIST). A target torque (MSL) is determined from the rotational speed-control deviation (dn) via a rotational speed controller as a master controller. A target injection duration (SD(SOLL)) is determined from the target torque (MSL). The target duration injection (SD(SOLL)) represents the set point for an inner control loop for controlling cylinder-specific injection duration. An injection duration deviation is determined from the target injection duration (SD(SOLL)) and from an actual injection duration.

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: 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.
