Definitions

  • the invention relates to a method for operating a navigation device, which additionally receives with a tuner TMC data for determining an optimal driving route, as well as a correspondingly designed navigation device.
  • Navigation devices are known and familiar in various embodiments. They essentially comprise a position-determining device which determines its position on the earth's surface in a manner known per se with the aid of signals which are emitted by GPS satellites or, in the future, the Galileo satellites. Furthermore, a route guidance device is known, which starting from this position, a route to one of the
  • TMC data (English: Traffic Message Control).
  • TMC data are transmitted by radio stations and received by the navigation device or system with a tuner suitable for this purpose. In doing so, these TMC data become parallel to the actual
  • Radio signals so for example a piece of music, broadcast.
  • the information which radio stations or on which frequencies these TMC data are broadcast are likewise deposited on the CD-ROM intended for this country or region.
  • a disadvantage here is to be considered that the navigation device always tries with the associated tuner or radio receiver to receive for all countries that are stored on the CD-ROM or DVD, the corresponding TMC data or to search a TMC transmitter.
  • the collection time is unnecessarily prolonged and the response time until all relevant TMC messages for the area being traveled is collected is too long.
  • the tuner is thereby overloaded with unnecessary tasks, so that even in known two-tuner concepts the problem occurs that a correct station search, for example, for RD S functionalities can not be performed.
  • the invention has the object to provide a method for operating a navigation device of the type mentioned with the guaranteed that even when driving over a national border traffic information can be reliably determined for consideration in the further calculation of the route. Furthermore, a suitably trained navigation device is to be created.
  • a navigation device collects in a conventional manner with the help of an additional tuner TMC data or messages for the currently traveled area or land and these messages are taken into account in the further calculation of a route, for example, a traffic jam dodge in time.
  • the navigation device is hardware and / or software designed such that when approaching a national border is automatically searched by the tuner for TMC data from the next country to be driven. For this purpose, from the tuner of the receivable frequency range for stations from the next area to be traveled be searched, in which case special search is made for stations whose country code, which is also always broadcast with the country code of the next country to be traveled.
  • the corresponding information about the country code or about the transmitters that transmit TMC data can also be stored on the exchangeable data carrier with the information about the route and road network of the currently traveled area.
  • the approach to a country border can be easily determined by the navigation device, since the position of the navigation device and the location of the border are known. For example, with an approach of 50 kilometers to a country border, which is to be run over in accordance with the calculation of the route, the navigation device automatically starts the search for TMC data from the next country. Similarly, the navigation device may estimate a time to cross the country boundary based on the average speed and the distance to the boundary, and e.g. Begin collecting TMC data half an hour before crossing the border. Of course, in this case several transmitters of a transmitter chain, each transmitting on different frequencies, can be set one after the other.
  • the advantage of the invention is that the method can be implemented in a simple manner in the navigation device, so that virtually no additional expense is incurred in its production.
  • the tuner had already been tuned to a first radio station for some time and all essential TMC data for the previously traveled country was collected and contained in a corresponding memory in the navigation device. As this country is about to leave anyway, there is almost no need to search for traffic reports for that country, so that the tuner will be available to determine the TMC data from the next country.
  • the second tuner With a two-tuner concept, as it is characterized in the claims 2 and 6, it is possible with one of the two tuners, here called the second tuner, already before crossing the country border after the TMC data from the next to be driven Searching for land while the first tuner associated with the navigation device continues to collect TMC data from the current country.
  • the tuner or tuners search for TMC data in more than one other country. This is particularly relevant when driving through several countries, such as Germany via Luxembourg to France, because already here the future route to a trouble-free traffic flow can be checked.
  • TMC data consists essentially of the fact that based on the information stored on a removable data storage on the
  • Radio stations of the individual countries such a transmitter of the next to be driven country is selected, which transmits TMC data.
  • the second tuner is set to this transmitter or to this transmitter chain to collect the TMC data and to transmit in a conventional manner the destination guidance device of the navigation device for calculating an optimal route. If this is not possible, since there are no TMC stations in the next country, for example, the second tuner can be occupied with other tasks for as long or, after a certain waiting time, be prompted to automatically search for TMC data from the next To look for land.

Abstract

La présente invention se réfère à un procédé pour l'utilisation d'un appareil de navigation qui utilise de plus un syntoniseur pour recevoir des données TMC pour la détermination d'un itinéraire optimal et avec lequel la détermination d'un itinéraire optimal est également possible au-delà des frontières nationales, l'invention prévoyant qu'à l'approche d'une frontière le syntoniseur recherche des données TMC provenant du pays suivant à traverser. L'invention concerne également un appareil de navigation conçu en conséquence.
