Problems solved by technology

However, there is an aging of this speed information such that in some cases the driver is informed of a maximum speed that is too low or too high for the road segment that he is currently traveling through the vehicle
This can cause the driver to exceed the maximum permitted speed, which may incur additional driving costs in the form of fines

Embodiment Construction

[0028] In the following description of a preferred exemplary embodiment of the present invention, the same or similar reference symbols are used in different drawings to designate similarly acting elements, wherein a repeated description of these elements is omitted.

[0029] figure 1 A block diagram of a vehicle 100 is shown, in which a navigation device 110 is provided which has an embodiment of a data processing device 120 according to the invention for carrying out the steps of the method according to the invention. The navigation device 110 also includes a memory 130 in which, for example, a digital street map 135 is stored. The digital street map 135 includes, for example, a network of road segments representing streets or paths between individual geographic locations. These road sections can be associated with speed limit information which indicates the maximum permissible driving speed of the vehicle on the road section concerned. In this case, the speed limit inform...

Abstract

The invention relates to a method for providing speed warning information to a navigation device, wherein the method comprises the step of reading in at least one first speed limit information about a selected road section, wherein the information is transferred from a first data transfer channel The first speed limit information is read into the data combining unit of the navigation device. Further comprising the step of reading at least one second speed limit information related to the selected road segment into the data combining unit of the navigation device from a second data transfer channel, wherein the first data transfer channel Physically independent from the second data transfer channel. Finally, combining the first speed limit information with the second speed limit information to obtain speed warning information for the road section.

Description

technical field [0001] The invention relates to a method for providing speed warning information to a navigation device, a corresponding data processing device and a corresponding computer program. Background technique [0002] In order to increase driver comfort, the speed limit for the vehicle on the road the vehicle is currently driving is often displayed in the navigation device. For example, the speed limit is read from separate data of a digital street map, or is added as an attribute depending on the road segment and is read by the navigation device and displayed to the driver of the vehicle. In this way, the driver is informed that the speed limit is just in effect. However, there is an aging of this speed information such that in some cases the driver is informed of a maximum speed that is too low or too high for the road segment that he is currently traveling through the vehicle. This can cause the driver to exceed the maximum permissible speed, which may result ...
