Abstract: A control bus (165) permits the transmission of a message (205) of a predetermined message length. A method (300) for transmitting pieces of information on the control bus (165) includes transmitting a message (205). The message includes a first field (210) and a second field (215). The first field (210) contains a variable reference to a type of information, and the second field (215) contains a piece of information of the type of information referred to in the first field (210).

Abstract: A method (200) for operating an electrical vehicle circuit (115) of a motor vehicle (105) includes determining that a voltage of the vehicle circuit (115) drops below a predetermined threshold value while electric current from the vehicle circuit (115) flows through a consumer (130) on board the motor vehicle (105), lowering a voltage present at the consumer (130) in order to reduce the current flowing through the consumer (130), and successively raising the voltage present at the consumer (130).

Abstract: An electric drive unit (E) may include an electric motor (EM) and an electronic control unit (EE) for the open-loop control of the electric motor (EM). The electric motor (EM) has a stator unit (S) and a rotor (R). The electronic control unit (EE) is mounted on an electrically insulating carrier element (ET), where the carrier element (ET) is attached to the stator unit (S). Additionally, the stator unit (S) includes a stator core (SP), where the stator core (SP) is electrically conductively connected to a ground connection (EEG) of the electronic control unit (EE).
