Definitions

  • German patent application DE 103 22 559 A1 discloses a device and a method for updating a digital map, in which information for navigation or general location information is transmitted to a subscriber in a vehicle, digital map information being present on board the vehicle.
  • one of the difficulties of such information transfers has been that considerable differences exist between different cards of different manufacturers, which can lead to comparatively large deviations in determining a position within the card.
  • the known AGORA method performs a kind of "map matching" which makes it possible to correlate similarities between maps and thus to be able to approximate elements without having to know the deviations in detail, although the method requires the transmission of comparatively large amounts of data , which is relatively expensive.
  • the navigation device according to the invention and the method according to the invention for navigation according to the independent claims has the advantage that, despite a reduction in the amount of data to be transmitted to the subscriber from the center, an increase in the accuracy of the navigation or location determination and the hit rate of properly localized objects is made possible .
  • Another advantage is that the required computational effort in the terminal or at the subscriber for the correlation of the data is reduced. This results in that a lower transmission capacity and thus an increased cost efficiency in the calculation in the navigation device is possible.
  • the route calculation in the navigation device is accelerated, and it is the use of simpler processors possible, which further reduces the cost of the navigation device according to the invention.
  • Another advantage is that updating a digital card with higher precision is directly possible since location information received from the center can be correlated directly with the information of the existing map material of the digital map.
  • the difference between the subscriber location calculated on the basis of the satellite navigation signal and an assumption calculated via the digital map about the current location of the subscriber is provided as correction information for correcting the navigation based on the digital map.
  • the navigation device for installation in a motor vehicle or for use in a motor vehicle has an interface for connection to a vehicle component.
  • the satellite navigation signal is a signal corresponding to the commercial navigation service (CS, Commercial Service) of the GALILEO satellite navigation standard. This makes it advantageously possible to obtain a particularly accurate spatial resolution of a location information, so that the subsequent navigation process can be carried out particularly efficient and cost-effective as well as easy and uncomplicated.
  • the difference between the subscriber location calculated on the basis of the satellite navigation signal and an assumption calculated via the digital map about the current location of the subscriber is used as correction information for correcting the navigation based on the digital map.
  • the amount of information or data quantity to be transmitted from the center to the subscriber 50 can be considerably reduced by representing the discrepancies between the digital map stored at the subscriber and the current location of the subscriber essentially by means of a correction information are.
  • correction information is transmitted to the subscriber by the control center for at least one intended digital map. This makes it possible to further reduce the data stream to be transmitted because the location information transmitted by the center already takes into account the type of digital map present in the subscriber (in particular due to different manufacturers or providers of digital maps).
  • a further subject matter of the present invention is a method for generating and / or updating a digital map, wherein a subscriber receives a satellite navigation signal, wherein the instantaneous location is determined by means of the satellite navigation signal with a greater accuracy compared to the average accuracy of the digital map, wherein the difference between the subscriber location calculated on the basis of the satellite navigation signal and an assumption calculated based on the digital map over the current location of the subscriber is used as correction information for generating and / or updating the digital map.
  • Figure 1 is a schematic representation of the communication situation of a navigation device according to the invention with a representation of the effect of correction information
  • Figure 2 is a schematic representation of the installation situation of the navigation device in a motor vehicle.
  • FIG. 1 shows a navigation device 51 according to the invention as a participant 50 of a control center 40.
  • the control center 40 transmits to the navigation apparatus 51 or the subscriber 50 location information 100, which is normally contained in encoded form within a signal to be transmitted from the center 40 to the navigation apparatus 51.
  • the location information 100 was either requested by the navigation device 51, wherein a request, not shown in FIG. 1, was sent from the navigation device 51 to the center 40, or the location information 100 was transmitted from the center 40 to the navigation device 51 not requested, but sent unsolicited.
  • the location information 100 is, for example, a supplement to a digital map 200 present in the navigation device 51 or the subscriber 50, or else an update or adaptation of the digital map 200 to a current traffic situation or other location-relevant information.
  • the navigation device 51 does not merely include the location information 100 received from the center 40 into those in the navigation device 51 digital map 200, but also performs navigation to a location 10 corresponding to the location information 100.
  • the navigation device 51 performs a navigation algorithm which is based on the evaluation of a satellite navigation signal 300.
  • the satellite navigation signal 300 is transmitted by a satellite 301. By means of the satellite navigation signal 300, it is possible to detect the location 30 of the navigation device 51 with a comparatively high accuracy.
  • This location of the navigation device 51 which is also referred to below as the subscriber location 30, may under certain circumstances differ from the location 20 of the subscriber 50, assumed to be based on the navigation algorithm carried out on the digital map 200.
  • the assumed location 20 of the subscriber 50 is also referred to below as the assumption 200 about the current location of the subscriber 50 calculated on the basis of the digital map 200.
  • Term correction information 25 is called between the assumption 20 about the location of the subscriber 50 and the current subscriber location 30 (which is based on the satellite navigation signal 300 enabling a comparatively accurate location-finding) calculated on the basis of the digital map 200.
  • the navigation algorithm running in the navigation apparatus 51 based on the digital map 200 therefore performs a navigation from the assumption 20 calculated on the basis of the digital map 200 over the current location of the participant 50 to a virtual location 10 'of the location information 100, wherein the virtual location 10 'from location 10 of location information 100 ideally differs by the amount of correction information 25.
  • the navigation algorithm that is traversed within the navigation device 51 therefore ultimately performs a navigation from the calculated assumption 20 over the current location of the subscriber 50 to the virtual location 10 'of the location information 100, while the navigation device 51 is "really" from the subscriber location 30 of the navigation device 51 to the location 10 of the location information 100 moves.
  • 2 shows a schematic representation of the arrangement of the navigation device 51 according to the invention in a motor vehicle 60 is shown.
  • the navigation device 51 is connected to a vehicle component 61 by means of an interface 52.
  • the vehicle component 61 can be used to supply vehicle movement data or vehicle position data acquired by the navigation device 51 to increase the accuracy of the navigation process in the navigation device 51, in particular by means of sensors not shown in FIG. 2.
  • the vehicle movement data or vehicle position data is, in particular, a vehicle speed, one or more vehicle accelerations, rotational accelerations or the like.
  • the vehicle component 61 is, in particular, a car radio, a human-machine interface or the like.
  • the navigation device 51 according to the invention can be connected to the vehicle component 61, in particular by means of the interface 52, which according to the invention is provided in particular wirelessly, wherein, for example, a radio interface or an infrared interface or the like can be provided.
  • This may be, for example, a Bluetooth connection, a WLAN connection (Wireless Local Area Network) or an NFC connection (Nearfield Communication).
  • a wired interface for example a bus or a bus system, such as a MOST bus.
  • only the digital map 200 located in the navigation device 51 is generated or updated or only generated in partial areas by means of the location information 100 sent from the center 40.
  • the deviation from the digital map 200 already in the navigation device 51 is again determined by means of the correction information 25 and taken into account in the generation or updating of the digital map 200.
