Abstract: A method and system for controlling at least one predefined function of an electronic multi-function apparatus usable during travel by a vehicle driver is provided. The electronic multi-function apparatus is connected to a control unit of the vehicle by a communication link. Data of the vehicle driver and/or data on the journey is acquired, and on the basis of the acquired data at least one characteristic value which is characteristic of the degree of loading of the vehicle driver by his current vehicle control process is formed. The at least one predefined function of the electronic multi-function apparatus is controlled based on the at least one characteristic value in such a way that a degree of loading of the vehicle driver when using the function is matched to the degree of loading of the vehicle driver corresponding to the current vehicle control process.

Abstract: A device for determining at least one position of a mobile terminal includes at least one memory apparatus, a magnetometer sensor unit, a classification unit, and a position-determining unit to determine the position of the mobile terminal. The classification unit is configured to determine states, in particular operating states, of at least one electric motor and/or a vehicle driven by means of at least one electric motor using the magnetometer sensor data. The classification unit is also configured to store the determined states in the at least one memory apparatus. The position-determining unit reads out the states from the at least one memory apparatus and determines the at least one position of the mobile terminal with the help of the states.
