  • the company Google ® and others have in recent years in Germany and other countries around the world streets of some cities completely included. These data are available via the internet.

Disadvantageous, however, would be that the captured images reflect random situations and are not necessarily suitable for assisting a driver or an automatic driver's system to guide the vehicle. There are now many situations in which it would be desirable to have information in a motor vehicle about areas of the vehicle not lying in the current field of vision of the driver or sensors of the vehicle, regardless of whether other vehicles can detect these areas or Not.

  • track data are thus stored in a stationary device located in or on the travel path or in or at an access to the vehicle with a transceiver and a data memory; and from the stationary device these infrastructure data is transmitted to the motor vehicle wirelessly.

  • An approach of the motor vehicle to the stationary device is detected, for example with the aid of a positioning sensor using, for example, the Global Positioning System, GPS: it must simply determine the position of the motor vehicle itself and that of the stationary one Facility to be compared.
  • a request is sent from the motor vehicle to the fixed facility to obtain the travel route data.
  • This preferred embodiment of the invention has the advantage that the stationary device does not have to emit signals itself, so that the motor vehicle has the information that there is the fixed device at all.
  • a request can be sent from the motor vehicle to a stationary device in order to obtain the track data.
  • the driver recognizes, for example by means of a self-explanatory or well-known symbol on a base-fixed device, such as a building or a pillar, that track data is available here and actively queries it.
  • the motor vehicle gains driving-track data when driving on the travel path. transfers these to the stationary facility.
  • up-to-date infrastructure data is always available in the stationary device, which information can be transmitted to a later arriving vehicle, for example.
  • the configuration is preferably even such that the stationary device compares the transmitted track data with the previously stored track data and updates the track data according to a predetermined criterion in order subsequently to transmit the updated track data to a motor vehicle.
  • the predetermined criterion may include, for example, that a property of the travel path which may have changed, as described in the originally stored travel data, is checked for durability in its change: for example, the pavement of the travel route is changed (for example, at a private driveway) or if new parking spaces are drawn on a public road, this new property will be "learned" by the fixed installation, for example, if the corresponding new infrastructure data is transmitted a minimum number of times, if a minimum number of times other than one is selected To an increased degree, it is ensured that non-short-term changes in the surroundings of the vehicle on the roadway are communicated to a motor vehicle the next time: If, for example, a new tree is planted in the area of the track, this change must be recorded permanently For example, in a garage only a few boxes that are later cleared away, so the information about these boxes is not essential and should not go into the transmitted to the motor vehicle track data.
  • the stationary device is in turn coupled to sensors that acquire measurement data.
  • the stationary device compares the measurement data which its sensors have obtained with the previously stored route data and updates the route data according to a predetermined criterion in order subsequently to transmit the updated route data to a motor vehicle.
  • a "learning" of the environment takes place automatically by the stationary device and is therefore independent of how often a motor vehicle polls and transmits the corresponding data.
  • the track data makes contours of lane boundaries and / or obstacles (on or above the carriageway).
  • an automatic vehicle guidance system such as a parking aid, to at least support the route data in order to guide the vehicle.
  • the floor-mounted device comprises a data memory in which track data is stored for a track in the environment; it comprises a transceiver device which is designed to transmit the stored infrastructure data (to a requesting motor vehicle) upon request.
