Abstract: A control unit system includes a control unit on which a rights management system is set up, access permission information being retrievably stored by the rights management system, functions in executable form being stored on further control units of the control unit system, at least one of the further control units being configured as a query control unit set up to execute these functions, or not, based on access permission information stored in the rights management system, characterized in that the control unit also includes a device management system that is configured to establish a connection with a server via a communication interface and to provide the rights management system with an update of the access permissions received from the server via this interface.

Abstract: A computer system for vehicles is provided in which the functions are partitioned among the computers of the computer system. A first computer takes over the driving-related functions, while a second computer having greater computing power takes over entertainment-specific functions.

Abstract: A navigational device for guiding a vehicle within a network of traffic routes provides, for guidance purposes, a guide object that is shown in relation to the traffic route in such a manner that the guide object's movement represents driving maneuvers to be performed by the driver. The driver emulates the driving maneuvers shown to him/her and thus follows the previously calculated route.

Abstract: Method for navigating a vehicle in a road system is provided, in which method data is read from a data-storage medium and automatically transferred to a memory of a navigation device after the data medium is inserted into a data-media drive associated with the navigation device. The transferred data remains available for vehicle navigation even after the data medium is removed from the data-media drive.

Abstract: A driver information device with a map display is designed in such a way as to make the map display clear and easy to read. This is achieved, in cases where multiple special objects are situated at one location on the map, through the use of an indicator symbol representing such special objects, with a selection menu for selecting individual special objects, instead of displaying an individual symbol for each one of them.

Abstract: In order to create a method for making available driving lane recommendations for each driving direction relating to at least one curb and interlinked with one another, as well as a system related thereto, which improve the quality of the driving instructions provided by a navigation device via optimized processing of the driving lanes on roads, in particular at intersections, it is recommended that (a) a curb (10, 11, 12; 10?, 12?, 15?) be assigned at least one lane list (20) whose elements (20.a.1.1, 20.a.1.2, 20.a.2) contain lane information on the totality of the driving lanes assigned to the curb (10, 11, 12; 10?, 12?, 15?); (b) each of the driving lanes be assigned at least one lane data list (30; 40) whose elements (30.b.1, 30.b.2; 40.b.1, 40.b.2) each contain lane data information on the particular driving lane; and (c) each follow-on driving lane succeeding the driving lane be assigned at least one follow-on lane list (50; 60; 70) whose elements (50.c.1, 50.c.2, 50.c.3, 50.c.4; 60.c.1, 60.c.2, 60. c.
