The invention relates to a method for removing user-specific and/or drive-specific user data which are saved distributedly on multiple controllers in a motor vehicle. A trigger apparatus is provided, and the trigger apparatus checks whether a trigger condition has been satisfied. If the trigger condition has been satisfied, a specified common delete command is transmitted to the plurality of controllers of the motor vehicle via a data bus of the motor vehicle, and each controller carries out a specified delete routine if the controller has received the delete command from the data bus, said delete routine being used to overwrite and/or delete user data saved on the particular controller.

Method for removing user-specific and/or drive-specific user data in a motor vehicle, and corresponding motor vehicle

A method for accessing an electronic device of a vehicle driver outside the vehicle including providing a vehicle which assists the vehicle driver by at least one driver assistance system while driving the vehicle and providing an electronic device of the vehicle driver outside the vehicle which communicates with the vehicle. The method includes the reproduction inside the vehicle of data contents which are stored on the electronic device of the vehicle driver outside the vehicle while the at least one driver assistance system is active. The disclosure enables a vehicle driver to perform personal tasks via one of his/her personal electronic devices during the assisted driving of a vehicle.

Method for accessing a vehicle-specific electronic device

A switch unit for an Ethernet network having a switch and a microprocessor, the switch including at least three ports, which are connected to inputs and outputs of the switch unit, a signal detector and generator for detecting and initiating a bus activity being arranged in each case between the ports and the inputs and outputs of the switch unit. For each input and output an allocation rule to the other inputs and outputs of the switch unit is stored in a memory, the switch unit being designed such that when a bus activity is detected at a signal detector and generator, the assigned inputs and outputs of this input and output are read out from the memory and the associated signal detectors and generators are woken up so that they generate a bus activity at their inputs and outputs.

Switch unit, ethernet network, and method for activating components in an ethernet network

An apparatus for operating a data bus system of a motor vehicle having data bus segments, at least one of the data bus segments is designed to switch from an active state to a rest state and vice versa. In a first step, a communication requirement is detected of a first control device of a first data bus segment in the rest state. If a communication requirement of the first control device is detected, the first data bus segment is brought from the rest state into the active state. If a communication requirement of the first control device with a second control device outside of the first data bus segment is detected, all other data bus segments of the data bus system outside of the first data bus segment that are in the rest state are additionally activated across the board.
