Abstract: A hydraulic parking lock actuation module for a parking lock with a parking lock piston, which can be hydraulically actuated in a parking lock cylinder from an initial position in an actuation direction by applying an actuation pressure, and which is mechanically coupled to an actuation rod which can be fixed via an engaging device in order to act as a locking mechanism for the parking lock piston. In order to simplify the actuation of the parking lock, for actuating the parking lock piston and the locking mechanism for the parking lock piston, the hydraulic parking lock actuation module includes only one active actuation valve with a tank connection and a working pressure connection at which different hydraulic pressure levels are applied.

Abstract: An angle-measuring device is provided for a rotationally-driven linear actuator, which can be implemented into a clutch actuator. A rotor element has an axis of rotation and rotates concentrically with a rotor of a rotary drive for an axially movable linear actuator element. A measurement magnet arrangement is fixed relative to the rotor element and has a polarization. The polarization is oriented in such a way that the magnetic field lines can change with a rotation of the rotor element so as to enable the angle to be precisely determined from at least one measurement position. At one location, a 360-degree sensor is provided for measuring angular positions based on the measurement magnet arrangement. At another location, a revolution-counting sensor is provided for counting a number of revolutions carried out based on the measurement magnet arrangement.

Abstract: A drive unit (100) is provided with a first electric machine (110), a second electric machine (120), a first shaft (130) and an output shaft (140). A rotor (111) of the first electric machine (110) is rotationally fixed to the first shaft (130), and a rotor (121) of the second electric machine (120) is rotationally fixed to the output shaft (140). The drive unit (100) also includes a separating clutch (150) and a connection element (230) for the rotationally fixed connecting of an internal combustion engine, and a first gear ratio step (142) is arranged between the connection element (230) and the shafts (130, 140) with a gear ration i
