Abstract: An arrangement for a motor vehicle includes a master controller and a slave controller that use different reference-earth voltages and respectively comprise a transmission and a reception unit for shared data interchange. The transmission and reception units are connected to one another via a shared communication line. The communication line contains a diode that prevents a flow of current from the slave controller to the master controller. The master controller contains a pull-up resistor via which the shared communication line can be connected to a first reference-earth potential of the reference-earth voltage of the master controller.

Abstract: The invention relates to a connecting support (1) for holding motor electronics on a motor subassembly (2), the connecting support being located between at least two components (3, 4) arranged at a distance from each other on the motor subassembly (2), wherein the connecting support (1) has means (8, 9) by means of which said components (3, 4) are electrically connected to each other, and wherein the connecting support (1) has a supporting structure (5) to which at least individual elements (6, 7) of the motor electronics are fastened.

Abstract: A power circuit (10) for activating a drive unit for a wiper system of a motor vehicle has a circuit breaker (14) for activating the drive unit. According to the invention a heat accumulator (16) for absorbing heat accumulating in the circuit breaker (14) when the drive unit is in the blocked state is thermally connected to the circuit breaker (14). In the event of sudden heat generation in the circuit breaker (14) a majority of the resulting heat can be discharged quickly to the heat accumulator (16) such that the circuit breaker (14) can be smaller in size and the power circuit (10) enables use of a higher-ohm circuit breaker (14).

Abstract: The present invention relates to an electrical drive unit with an electric motor and a transmission, wherein the motor has a rotor shaft (6), to which a rotor (10) and a commutator (11) are fitted in a manner fixed against rotation, wherein a commutator sliding contact (23) is provided in order to make contact with the commutator (11), and wherein an electrical connection is provided between an electrical terminal (18) and the commutator sliding contact (23). According to the invention, one cable and one special step in the manufacturing process are dispensed with by virtue of the fact that the electrical connection runs via the rotor shaft (6).
