Abstract: A system for the ergonomic communication of a map portion is presented. The map portion may include map information, map background, and additional information. The system includes an interface control unit that may include a graphics control unit, a processor and a memory. The system may include one or more modules for creating an ergonomic presentation including: a border module that may add the additional information to the representation; an adaptation module for adapting the map information and map background and/or additional information with one another, such as within a maximum color contrast; a scale-dependent module that may adapt the color intensity and width of map information as a function of scale and type; and a smoothing module to increase the quality of the map portion representation. The system may include a method for controlling the representation of a map portion.

Abstract: To facilitate the operation of an in-vehicle navigation system and to shorten the time required for the otherwise time-consuming entering of the destination by crosshairs by reducing the operating steps required, a general map and an enlarged portion of the general map are displayed simultaneously on a screen. A navigation computer calculates the routes. Map data from general maps and detail maps are stored in a memory. A main computer calculates the portion selectable for example by crosshairs and shown on an enlarged scale, from the data stored in the memory. The general map and the enlarged portion can be moved synchronously with one another on the screen by a graphic control unit.

Abstract: A navigation unit, especially for vehicles, with a data bus, a data memory on which a plurality of map information items and navigation data are stored, with a navigation computer, connected to the data bus, for route planning, with a data processing unit, connected to the data bus, for processing the data into picture information, the data processing unit containing a picture memory for storing the picture information, with a monitor, connected to the data processing unit, on which the picture information can be displayed, with a communication block with a control unit for entering the start location, intermediate destination, and/or final destination of a trip, such that the data processing unit contains a map memory for storing road map information.

Abstract: A navigation unit, especially for vehicles, with a data bus (3), with a data memory (2) on which a plurality of map information items and navigation data are stored, with a navigation computer (1), connected to the data bus (3), for route planning, with a data processing unit (30), connected to the data bus (3), for processing the data into picture information, the data processing unit (30) containing a picture memory (32) for storing the picture information, with a monitor (4), connected to the data processing unit (30), on which the picture information can be displayed, with a communication block (20) with a control unit (21) for entering the start location, intermediate destination, and/or final destination of a trip, such that the data processing unit (30) contains a map memory (38) for storing road map information.
