Onboard information system with antenna for receiving satellite-based geoposition data
View Patent ↗An onboard information system having an antenna for receiving satellite-based geoposition data. The onboard information system includes a housing that can be installed in a vehicle interior and a module for processing satellite-based geoposition data. The antenna for receiving satellite-based geoposition data is arranged on the housing such that in the installed state a reception direction of the antenna points toward the vehicle interior. The onboard information system can be used particularly in a vehicle as a tachograph, preferably as a digital tachograph, and/or toll collection appliance.
1. An onboard information system for capturing at least one vehicle-related variable, comprising:
a housing configured to be installed in a vehicle interior;
a module for processing satellite-based geoposition data; and
an antenna for directly receiving the satellite-based geoposition data arranged on the housing such that in the installed state of the antenna a reception direction of the antenna points toward the vehicle interior,
wherein the antenna for receiving the satellite-based geoposition data provides the received satellite-based geoposition data directly to the module for processing satellite-based geoposition data.
2. The onboard information system as claimed in claim 1 , wherein the housing comprises a panel that covers only one side of the housing, wherein the housing has, in a region behind the panel, at least one mounting element for permanent installation in the vehicle interior.
3. The onboard information system as claimed in claim 1 , wherein the antenna is a patch antenna.
4. The onboard information system as claimed in claim 1 , wherein a reception body of the antenna is positioned centrally on a ground plane of the antenna.
5. The onboard information system as claimed in claim 4 , wherein the ground plane of the antenna comprises a printed circuit board which is laminated.
6. The onboard information system as claimed in claim 1 , wherein the antenna is fitted on a portion of the housing that protrudes into the vehicle interior.
7. The onboard information system as claimed in claim 1 , wherein the housing is configured to be installed in a pit having dimensions according to an ISO 7736 standard.
8. The onboard information system as claimed in claim 1 , wherein an electrically conductive portion of the housing is fitted on a side of the antenna that is remote from the reception direction of the antenna.
9. The onboard information system as claimed in claim 1 , further comprising:
a mobile radio antenna for receiving mobile radio signals; and
a mobile radio module coupled to the mobile radio antenna.
10. The onboard information system as claimed in claim 9 , wherein the mobile radio antenna and the antenna for receiving satellite-based geoposition data are arranged on opposite sides of the housing.
11. The onboard information system as claimed in claim 1 , wherein the onboard information system is configured as a tachograph, a digital tachograph, and a toll collection appliance.
12. A vehicle, containing an onboard information system as claimed in claim 1 , wherein the onboard information system is installed in a vehicle interior such that the reception direction of the antenna points toward the vehicle interior.
13. The onboard information system as claimed in claim 5 , wherein the printed circuit board is laminated with copper.
14. The onboard information system as claimed in claim 6 , wherein the antenna is fitted on a drawer.
15. The onboard information system as claimed in claim 1 , further comprises one of a tachograph, a digital tachograph, and a toll collection appliance.
