Abstract: A method for operating a motor vehicle having a camera device that records the area ahead of the vehicle and an associated control device for evaluating images taken by the camera device, wherein the control device evaluates the images in order to detect at least one hand gesture performed by a person shown in the images, wherein, when a hand motion describing a calling gesture that indicates a stop request is detected, in the case of a self-driving motor vehicle, the motor vehicle is controlled to stop in the vicinity of the person, or in the case of a non-self-driving motor vehicle, the driver of the motor vehicle is given a signal indicating the stop request.

Abstract: A method for operating a vehicle charging apparatus for charging a vehicle battery. A particular line on the decoupling-point side is initially assigned to the first line on the charging-apparatus side by changing the charging current of a particular line on the charging-apparatus side and evaluating the line on the decoupling-point side in which a change can likewise be determined. This process is repeated for at least one second line on the charging-apparatus side.

Abstract: A charging device including a first interface, by which the first connection between the charging device and a local network can be established; a second interface by which a second connection between the motor vehicle and the charging device can be established so that when the first connection is established, a data exchange between the local network and the motor vehicle is possible; at least one further interface by which a further connection between a further participant and the charging device can be established so that when the first connection is established, a data exchange between the local network and the further participant is possible; and a control device that is designed to request a predefined certificate from the vehicle and to establish the further connection without requesting and authenticating the predefined certificate.

Abstract: The present disclosure relates to a method for operating an electric motor, wherein a vehicle dynamics controller transmits a driving-performance-related torque setpoint to an acoustic controller configured as a control device. The acoustic controller receives an input value for defining an acoustic signal as well as a phase angle of a rotor of the electric motor from the power electronics as well. To generate a dynamic torque setpoint, the acoustic controller modulates onto the driving-performance-related torque setpoint at least one torque pattern that depends on the phase angle of the rotor of the electric motor, wherein the dynamic torque setpoint is such that a sound according to the input value is generated by the electric motor and/or a drive train. The dynamic torque setpoint is transmitted to power electronics.

Abstract: A method for operating a charging device for a battery of a motor vehicle. The charging device converts electric power obtained from a motor vehicle-external, three-phase energy system supplying other consumers in an infrastructure unit, in particular a house, by a converter device into an electric current that is suitable for charging the battery, and supplies electric energy of the battery by the converter device into the energy system. The charging device receives in an operating phase phase-resolved power data, which is fed to the energy system and measured by a measuring device, and determines phase-specified target power while using phase-related power data outputs for each phase. The target power that is determined for each phase is retrieved from each phase.
