Abstract: A door drive for a motor vehicle door or motor vehicle flap, which is provided with an electromotive drive, a transmission downstream of the drive, and a force-transmission element. The force-transmission element is operatively connected to a leaf of the motor vehicle door or motor vehicle flap. An output element of the transmission and the force-transmission element are coupled by a toothing with compensation for play. According to the invention, the output element and/or the force-transmission element are not only designed to be moveable for play compensation, but can also be permanently fixed after the compensation for play.

Abstract: A motor vehicle lock, in particular a motor vehicle door lock, which is equipped with a locking mechanism essentially consisting of a rotary latch and a pawl. Furthermore, an actuating lever chain for the locking mechanism is provided. The actuating lever chain has at least one actuating lever, a coupling element, and a trigger lever on the locking mechanism side. Furthermore, an inertia element is also provided for acting on the coupling element at least in the event of a crash. According to the invention, the coupling element is disengaged during normal operation and is only engaged in the event of a crash by means of the inertia element.

Abstract: The disclosure relates to a method for determining phase currents of a rotating multiphase electrical machine fed by means of a PWM-controlled inverter. In this case, injection voltages applied in at least one stipulated PWM period are determined. An evaluation direction for a phase current vector is also determined and a division of current measurements for the individual phase currents is determined on the basis of the evaluation direction. The phase currents are then determined on the basis of the previously determined division of the current measurements.
