Abstract: A method for operating a dual-clutch transmission having a first partial transmission, a second partial transmission, a first clutch assigned to the first partial transmission, and a second clutch assigned to the second partial transmission, in which the dual-clutch transmission is shifted into a parking lock state. The dual-clutch transmission is shifted into the parking lock state by the following steps: while a first gear of one of the partial transmissions is engaged: carrying out an engagement process provided for engaging a second gear of the one partial transmission; determining that the second gear is not engaged despite the engagement process being carried out; selecting a third gear of the dual-clutch transmission different from the first gear and from the second gear; and engaging the selected third gear such that in the park lock condition, the first gear and the third gear are at least temporarily engaged simultaneously.

Abstract: A wheel bearing arrangement for a motor vehicle, having a wheel hub and a wheel bearing for rotatably mounting the wheel hub on a wheel carrier. The wheel bearing has an outer ring and an inner ring. A wheel flange extends from the wheel hub in a radial direction and has a brake disc receptacle which is open in the direction facing away from the outer ring and is formed by a recess in the wheel flange and has a brake disc bearing face for a brake disc. A seal-receptacle space is formed in the wheel flange on its side facing the outer ring in an axial direction, in which seal-receptacle space there is a wheel bearing seal. A rim-centering seat element extends from the wheel hub and runs in the direction opposite the brake disc bearing face with respect to the brake disc receptacle.

Abstract: A method for operating a dual clutch transmission of a motor vehicle having a first partial transmission, a second partial transmission, and a transmission output shaft common to the partial transmissions and drivable both by the first partial transmission and by the second partial transmission, in which the dual clutch transmission is in a parking lock state in which two gears of one of the partial transmissions are engaged simultaneously. The following steps are carried out to exit the parking lock state: Introducing a torque caused by a drive element of the motor vehicle via the transmission output shaft common to the one partial transmissions into the one and/or other partial transmission while the gears of the partial transmission are engaged; and disengaging at least one of the gears of the one partial transmission engaged simultaneously in step a).

Abstract: A method of operating virtual reality glasses in a vehicle in which a risk of motion sickness for a wearer of the virtual reality glasses is reduced with the aid of the method. A virtual reality system (IO) includes the virtual reality glasses and the vehicle. According to the method, a vehicle movement of the vehicle is evaluated in such a way that ultimately, after the image data describing the virtual surroundings have been split into a background image dataset and a foreground image dataset, a lateral offset for a position of an object in the foreground in comparison with the background is determined, so that virtual surroundings which are processed in this way can be determined and displayed. Alternatively, the virtual surroundings can be enlarged in accordance with the vehicle movement, and processed virtual surroundings can be determined by means of a movement of the enlarged virtual surroundings along a movement trajectory, and displayed.

Abstract: A power network for a motor vehicle includes a first partial power network connected to a supply potential, a second partial power network, and a coupling element which couples the second partial power network to the supply potential via the first partial power network. The coupling element has a reversible disconnect function, such that the coupling element reversibly decouples the first partial power network from the second partial power network based on a physical value of the first partial power network.

Abstract: A method for operating a motor vehicle. The motor vehicle has a drive unit which is designed in such a way that, in case of acceleration, the motor vehicle is accelerated using a continuous torque output. The drive unit is operable in a first and second operating mode. In the first operating mode the motor vehicle is accelerated without interruption by the continuous torque output, and in the second operating mode the continuous torque output is changed over to a stepped torque output, so that in the second operating mode the motor vehicle is accelerated subject to interruption by the stepped torque output.

Abstract: An electric power converter device includes a first power semiconductor module and a frame for a closed cooler. The first power semiconductor module includes a first base plate having a first main side, a second main side opposite the first main side and a lateral side surface extending along a circumferential edge of the first base plate and connecting the first and the second main side. The frame is attached to the second main side of the first base plate. The first base plate has a first step on the second main side along the circumferential edge of the first base plate to form a first recess along the circumferential edge of the first base plate, in which first recess a first portion of the frame is received.

Abstract: The described examples may relate to a method of operating an on-board power supply of an electrically drivable motor vehicle, in which at least one electrical machine is supplied with electrical energy from a vehicle battery connected to the on-board power supply via an inverter connected to the on-board power supply in an intended drive operation, and the inverter may include a radio interference suppression filter to reduce grid-bound interferences. In an example, at least the inverter may be electrically disconnected from the on-board power supply in a charging operation.
