Abstract

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.

Claims

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 receiving 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.

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 one of the preceding claims, 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.
