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 system includes a partition element (4) and a first component (1) which is arranged on a first side of the partition element (4). The first component (1) includes at least one conductor (9), and the partition element (4) includes an associated feedthrough (5) for inserting and feeding through the conductor (9) and for electrically contacting the conductor (9) on a second side of the partition element (4) located opposite the first side. The conductor (9) forms a form-fitting connection to the feedthrough (5) and is pressed into the feedthrough (5).

Abstract: A method for operating an electric motor-driven refrigerant compressor of a motor vehicle is provided. A first temperature of a power semiconductor is measured, and a second temperature of the power semiconductor is determined using a theoretical model of the motor-driven refrigerant compressor. A difference between the first temperature and second temperature is determined. A fault is detected if the difference is greater than a first threshold. The invention further relates to a motor-driven refrigerant compressor of a motor vehicle, to the use of a motor-driven refrigerant compressor, and to a motor vehicle comprising a refrigerant circuit.

The system has a partition element (4) and a first component (1) which is arranged on a first face of the partition element (4). The first component (1) has at least one conductor (9), and the partition element (4) has a paired feedthrough (5) for introducing and feeding through the conductor (9) and electrically contacting the conductor (9) on a second partition element (4) face opposite the first face. The conductor (9) forms a formfitting connection with the feedthrough (5) and is pressed into the feedthrough (5).

Abstract: An operating mechanism for a folding top (1) of a convertible has an electric motor (10) with a rotational speed that can be regulated for driving a hydraulic gear mechanism (11). A control unit (7) for actuating the electric motor (10) has a memory (18) for rotational speeds intended according to the positions of the folding top (1). As a result, the rotational speeds are stored as software that is easy to change.

Abstract: A parking aid for a motor vehicle, which measures the distance between an object and the motor vehicle in a contactless manner and has a plurality of sensors which are arranged on the motor vehicle, each sensor emitting a signal and receiving the signal reflected from an object located in the direction of the beam, and an evaluation device connected to the sensors determining the distance between the object and the motor vehicle from the signals received. The outlay for electrically synchronizing the sensors is reduced and which nevertheless allows reliable detection of the actual object for accurate measurement of the distance, has three sensors which are arranged directly next to one another to provide approximate coverage of the same detection area, whereby the main beam of each sensor having approximately the same beam angle.
