Abstract: A method for operating a brushless electric motor of a motor vehicle, particularly an electromotive refrigerant compressor, with two sub-motors arranged in sections and each comprising n-phases, by means of a converter corresponding to the number of phases of the electric motor. On the basis of a performance requirement, first switching points are determined for the n-phases, of one of the sub-motors, and on the basis of the performance requirement, second switching points are determined for the n-phases of the other sub-motor. The second switching points are shifted by a first phase angle and the converter is controlled on the basis of the first switching points and the second switching points. The first phase angle is selected such that a resulting current flow over the converter is smaller than a first threshold value. A unit of a motor vehicle, comprising a brushless electric motor is also disclosed.

Abstract: A haptic control device, particularly for motor vehicles, with a touchpad including at least one contact-sensitive touch. A control signal can be triggered upon contact with the touch region, and the touchpad can be moveably driven by a drive in the plane of the touchpad in a certain rhythm. The touchpad is connected to a stationary carrier by one or more flexible connecting elements. The flexible connecting element or elements are spring arms, one end of which is connected to the carrier and the other end of which is connected to the touchpad.

Abstract: A haptic operating device particularly for motor vehicles, having a touch panel having at least one touch-sensitive area. When the area is touched, a switching signal can be triggered and the touch panel can be activated by a motion drive to be able to move at a certain rhythm in the plane of the touch panel. The touch panel is connected to a fixed support by one or more flexible connecting elements. The support and the touch panel form two housing parts of a closed housing, in which at least the display device or the display plane thereof is arranged, and are connected to each other by a sealing device so as to be able to move relative to each other in the plane of the touch panel or in a plane parallel to the touch panel.

Abstract: A motor-generator system of a hybrid drive with an internal combustion engine (ICE) and an electric machine (EM) connected to an energy storage device (BA) via a converter device (CD). The motor-generator system can be used in addition to supply external power consumers (PC) in isolated operation, with little incremental complexity. For this purpose, the electric machine (EM) includes, in addition to a first stator winding (W1) for traction operation, a second stator winding (W2) for isolated generator operation. The second stator winding (W2) is advantageously coupled in transformer-fashion to the first stator winding (W1) and can thus be supplied with magnetizing current from the energy storage device (BA) via the converter device (CD).

Abstract: An intake device has a flange, at which it can be attached to a flange of a cylinder head. Intake pipes are furthermore provided, which are configured as at least two inlet ducts per cylinder. At least in the region of the flange of the intake device, the free cross section of at least one of the intake ducts in each case is capable of being closed by a flap. The flange and the flap with a shaft and a bearing are formed in such a way that the flap can be introduced with the shaft and the bearing in front of that side of the flange that faces the cylinder head.
