Abstract

A position determining arrangement for a vehicle includes: a receiving device, in particular an antenna, designed to receive a navigation satellite signal from a navigation satellite; a processing device designed to provide a first signal depending on the received navigation satellite signal, the first signal describing a navigation satellite signal-based position of the receiving device in a coordinate system; at least one inertial sensor designed to detect an acceleration and/or a rate of rotation; a computing unit designed to determine an adapted position of the receiving device in the coordinate system depending on the first signal and the detected acceleration and/or rate of rotation; and a first housing in which at least the computing unit is located. The position determining arrangement includes a second housing independent of and spatially separated from the first housing, and the inertial sensor is located in the second housing.

First claim

The invention claimed is:

1. A position determining arrangement for a vehicle, comprising:
a receiving device configured to receive at least one navigation satellite signal from at least one navigation satellite;
a processing device configured to provide a first signal depending on the received navigation satellite signal, said first signal describing a navigation satellite signal-based position of the receiving device in a coordinate system;
at least one inertial sensor configured to detect at least one of an acceleration and a rotation rate;
a computing unit configured to determine an adjusted position of the receiving device in the coordinate system depending on the first signal and the at least one of the acceleration and the rotation rate;
a first housing in which at least the computing unit is arranged; and
a second housing independent of and spatially separated from the first housing,
wherein the inertial sensor is arranged in the second housing.

2. The position determining arrangement as claimed in claim 1 , wherein:
the position determining arrangement is part of a vehicle, and
the first housing and the second housing are arranged in the vehicle so as to be spatially separated from each other.

3. The position determining arrangement as claimed in claim 2 , wherein the vehicle is a motor vehicle.

4. The position determining arrangement as claimed in claim 1 , wherein the inertial sensor is arranged in a ceramic housing.

5. The position determining arrangement as claimed in claim 4 , wherein the ceramic housing is arranged in the second housing or formed by the second housing.

6. The position determining arrangement as claimed in claim 1 , further comprising:
an evaluation device configured to provide a second signal representing a correction value that is based on at least one correction service satellite signal received from at least one correction service satellite via the receiving device or a receiver of the position determining arrangement that is configured to receive the correction service satellite signal.

7. The position determining arrangement as claimed in claim 6 , wherein the processing device and/or the evaluation device are arranged in the first housing.

8. The position determining arrangement as claimed in claim 6 , wherein the processing device and/or the evaluation device are arranged outside the first housing.

9. The position determining arrangement as claimed in claim 6 , wherein the processing device is integrated into the receiving device and/or the evaluation device is integrated into the receiver.

10. The position determining arrangement as claimed in claim 1 , wherein the computing unit is connected to the inertial sensor for communication purposes via a field bus, an Ethernet connection, and/or a radio connection.

11. The position determining arrangement as claimed in claim 10 , wherein the computing unit is connected to the inertial sensor via a CAN bus or FlexRay bus.

12. The position determining arrangement as claimed in claim 1 , wherein the inertial sensor is connected to a control unit.

13. The position determining arrangement as claimed in claim 12 , wherein the control unit is an airbag control unit and/or a vehicle dynamics management control unit.

14. The position determining arrangement as claimed in claim 1 , wherein the computing unit is integrated into a control unit.

15. The position determining arrangement as claimed in claim 14 , wherein the control unit is an airbag control unit, a vehicle dynamics management control unit, and/or a vehicle central control unit.

16. The position determining arrangement as claimed in claim 1 , further comprising at least one additional inertial sensor.

17. The position determining arrangement as claimed in claim 1 , wherein one or more sensors of the at least one inertial sensor is arranged in a region of a transmission tunnel of the vehicle.

18. The position determining arrangement as claimed in claim 1 , wherein one or more sensors of the at least one inertial sensor is arranged on a chassis or bodywork of the vehicle.

19. The position determining arrangement as claimed in claim 1 , wherein the receiving device is an antenna.

20. A motor vehicle comprising:
a position determining arrangement comprising:
a receiving device configured to receive at least one navigation satellite signal from at least one navigation satellite;
a processing device configured to provide a first signal depending on the received navigation satellite signal, said first signal describing a navigation satellite signal-based position of the receiving device in a coordinate system;
at least one inertial sensor configured to detect at least one of an acceleration and a rotation rate;
a computing unit configured to determine an adjusted position of the receiving device in the coordinate system depending on the first signal and the at least one of the acceleration and the rotation rate;
a first housing in which at least the computing unit is arranged; and
a second housing independent of and spatially separated from the first housing, wherein the inertial sensor is arranged in the second housing.
