Abstract: A method operates an onboard power supply system in a motor vehicle. The onboard power supply system has a master controller and a slave controller, in which the master controller communicates with the slave controller via a subsidiary bus system and a further onboard power supply system component via a main bus system. Present requests are received in the slave controller and in response to the present requests, performing one of: putting the slave controller into an operating mode and switching the master controller to a transmission mode, in which the master controller coordinates communication between the slave controller and the onboard power supply system component; or putting the slave controller into a sleep mode and switching the master controller to an undertaking mode, in which the master controller responds to queries from the onboard power supply system component to the slave controller.

Abstract: The invention relates to a drive configuration for the motorized displacement of a displacement element of a motor vehicle, at least one drive having an electrical drive motor, in particular a DC motor, and a drive controller, which is associated with the drive and connected to a supply voltage UV, being provided, the drive not being designed as self-locking, so that in the case of a non-motorized displacement of the displacement element, the drive motor operates as a generator and generates a generator voltage UG. It is proposed that the drive controller is equipped with an overvoltage protector, which can be triggered by exceeding a limiting supply voltage UV, and that the configuration is further made so that the overvoltage protector can additionally be triggered by a non-motorized displacement of the displacement element if a limiting generator voltage UG is exceeded.

Abstract: A method for controlling a vehicle seat adjuster in an adjusting path having a first mechanical stop and a second mechanical stop. A user sets an adjustment position of the adjuster inside the adjusting path. A protective stop is also automatically set in the adjusting path in the vicinity of the mechanical stops or another mechanical block blocking the adjusting path. The protective stop causes the adjusting motion to be reduced or stopped upon reaching of the protective stop. This helps produce a smooth braking of the vehicle seat and reduces the mechanical strain on the mechanical stops. The protective stop may be corrected with an updated protective stop. The updated protective stop is maintained despite any user action if a condition dependent on the adjusting motion of the adjuster is fulfilled. Learning regions within the adjusting path are provided to allow the setting of updated protective stops within the learning regions.

Abstract: The invention relates to a method for controlling an adjuster on a motor vehicle, in particular for a motor vehicle seat adjustment, with at least one adjustment range between a first stop and a second stop. An adjustment position for the adjuster may be set within the adjustment range by means of a user action, said adjustment position determined within the adjustment range and a protective stop set in the adjustment path, which, depending on the adjuster position, triggers a reduction in the adjustment energy, in particular to stop the adjustment movement in the vicinity of a mechanical block for the adjustment movement. According to the invention, in order to correct the position of the protective stop, a new protective stop is set, which may not be inactivated by a user action, when a condition, dependent on the adjuster motion of the adjuster device is fulfilled.
