Embodiment Construction

[0026] figure 1 The device 1 is shown schematically in the form of a line diagram. The device 1 has as a core component a control unit 13 which can be arranged in a motor vehicle. Furthermore, a position receiving unit 10 is shown, which is embodied as a navigation system and which can likewise be arranged in a motor vehicle in a known manner. The illustration only shows the components in their arrangement by way of example, and all units can be arranged in a smartphone or a mobile navigation system. It is not essential that the position receiving unit is arranged in the vehicle or that it is part of the navigation system. The position receiving unit 10 is used to provide position information 14 which can be given in particular to the control unit 13 .

[0027] According to the invention, device 1 has a position sensor 11 , which can be arranged, for example, in the motor vehicle itself or in a hand-held terminal which, on the other hand, is likewise accommodated in the mot...

Abstract

The device (1) has position obtaining unit (10) which is formed for determining a position on a traffic road. The device further comprises a position sensor (11) for sensing position information (12) and a control unit (13) for transmitting the position information (14) obtained from position obtaining unit and the position information from the position sensor. A slope calculation unit (15) is provided for receiving the location information from the position sensor and for determining a gradient information (16) on the slope of the road at a particular position. Independent claims are included for the following: (1) a method for accumulation of road data; and (2) a computer program product for accumulation of road data.

Description

technical field [0001] The invention relates to a device for enriching road data, which has a position receiving unit designed to determine a position on a traffic road. Furthermore, the invention relates to a method for enriching road data with such a device as well as a computer program and a computer program product therefor. Background technique [0002] Navigation devices are known which have a position receiving unit and which receive position data, for example in the form of GPS data, GALILEO data, via satellite or via mobile wireless telemetry for navigation on traffic roads. In a known manner, road data relate to the geographical location of traffic roads and can be enriched with so-called points of interest or with long-term or real-time updated traffic information or traffic instructions. [0003] Furthermore, it is known to store altitude information about the terrain altitude of the traffic road and, for example, if the motor vehicle is moving on the traffic ro...
