Onboard-installation for a vehicle
First Claim
1. An onboard unit for a traffic telematics system, comprising:
- a first communication module in the onboard unit, configured to generate or process near-range radio communications with a first external communication device, the first communication module comprising first processing circuitry;
a second communication module in the onboard unit that is separate from the first communication module, configured to generate or process far-range radio communications with a second external communication device, the second communication module comprising second processing circuitry that is separate from the first processing circuitry; and
a non-volatile memory in the onboard unit for storing data related to traffic telematics, the non-volatile memory configured to be accessed both by the first and second communication modules for the data related to traffic telematics;
wherein each communication module has a power-supplied communication mode and a powerless or power-saving rest mode;
wherein whether the first communication module is in its power-supplied communication mode or its powerless or power-saving rest mode is independent of whether the second communication module is in its power-supplied communication mode or its powerless or power-saving rest mode; and
wherein power to the memory is only supplied when the first or the second communication module accesses the memory for the data related to traffic telematics.

Abstract
The present subject matter relates to an onboard unit for a traffic telematics system, comprising: a first communication module, designed for near-range radio communication with a first external communication device, a second communication module, designed for far-range radio communication with a second external communication device, and a non-volatile memory, which can be accessed both by the first and the second communication module, wherein each communication module has a power-supplied communication mode and a powerless or power-saving rest mode, and wherein the power supply of the memory during an access thereto is effected by the accessing communication module. The present subject matter further relates to an onboard system for a vehicle comprising such an onboard unit, and to a communication device for said system.

16. An onboard system for a vehicle, comprising:
-
an onboard unit that includes; a first communication module in the onboard unit, configured to generate or process near-range radio communications with a first external communication device, the first communication module comprising first processing circuitry, a second communication module in the onboard unit that is separate from the first communication module, configured to generate or process far-range radio communications with a second external communication device, the second communication module comprising second processing circuitry that is separate from the first processing circuitry, and a non-volatile memory in the onboard unit for storing data related to traffic telematics, the non-volatile memory configured to be accessed both by the first and second communication modules for the data related to traffic telematics, wherein each communication module has a power-supplied communication mode and a powerless or power-saving rest mode; wherein whether the first communication module is in its power-supplied communication mode or its powerless or power-saving rest mode is independent of whether the second communication module is in its power-supplied communication mode or its powerless or power-saving rest mode; and wherein power to the memory is only supplied when the first or the second communication module accesses the memory for the data related to traffic telematics, the first communication module being a passive near field communication (NFC) tag configured to receive power via radio, and the memory of the onboard unit containing an identification of the onboard unit configured to be read out via the first communication module; and a further NFC tag, separate from the onboard unit, which contains a radio-readable identification of the separate further NFC tag. - View Dependent Claims (17, 18)

19. An onboard unit for a traffic telematics system, comprising:
-
a first communication module in the onboard unit, configured to generate or process near-range radio communications with a first external communication device, the first communication module comprising first processing circuitry; a second communication module in the onboard unit that is separate from the first communication module, configured to generate or process far-range radio communications with a second external communication device, the second communication module comprising second processing circuitry that is separate from the first processing circuitry; and a non-volatile memory in the onboard unit for storing data related to traffic telematics, the non-volatile memory configured to be accessed both by the first and second communication modules for the data related to traffic telematics; wherein each communication module has a power-supplied communication mode and a powerless or power-saving rest mode; wherein whether the first communication module is in its power-supplied communication mode or its powerless or power-saving rest mode is independent of whether the second communication module is in its power-supplied communication mode or its powerless or power-saving rest mode; and wherein a power supply is connected to the memory via a switch, and wherein power is only supplied to the memory when the first or the second communication module controls the switch to supply the power via the power supply and accesses the memory for the data related to traffic telematics.
