Abstract

The invention relates to the management of a scheduled temporary shutdown of an electronic component (ECU) monitored by a supervisory device (VSM), the component and the device being comprised on board a land motor vehicle.

First claim

The invention claimed is:

1 . A method for managing a scheduled temporary shutdown of an electronic monitored component monitored by a supervisory device and by a secondary component, the monitored component, the supervisory device, and the secondary component being comprised on board a land motor vehicle, the method comprising steps of:
the monitored component identifying the scheduled temporary shutdown; the monitored component generating a shutdown anticipation message comprising information regarding a duration of the scheduled temporary shutdown of the monitored component; the monitored component transmitting the shutdown anticipation message to the supervisory device; the supervisory device stopping monitoring of the monitored component for the duration of the scheduled temporary shutdown as indicated by the information on the duration of the scheduled temporary shutdown in the shutdown anticipation message, the supervisory device, upon the receipt of the shutdown anticipation message, transmitting a secondary information message to the secondary component; the secondary information message comprising the information on the duration of the scheduled temporary shutdown of the monitored component; and, the secondary component stopping the monitoring of the monitored component for the duration of the scheduled temporary shutdown as indicated by the information in the shutdown anticipation message.

2 . The method as claimed in claim 1 , wherein the shutdown anticipation message further comprises at least one of:
an identifier of the component; and information configured to explain a reason for the scheduled temporary shutdown.

3 . The method as claimed in claim 1 , further comprising the steps of:
upon the monitored component identifying a restart of the monitored component, the monitored component sending a resume information message to the supervisory device; upon the supervisory device receiving the resume message, the supervisory device resuming monitoring of the monitored component.

4 . The method as claimed in claim 1 , wherein the monitoring by the supervisory device comprises periodically receiving verification messages from the monitored component, which are configured to inform the supervisory device of normal operation of the component.

5 . A computer program comprising instructions for implementing the method as claimed in claim 1 , wherein these instructions are executed by a processor.

6 . A system configured to manage a scheduled temporary shutdown of an electronic monitored component monitored by a supervisory device and by a second component, the system comprising the supervisory device, the second component, and the monitored electronic component, the system being on board a land motor vehicle,
the monitored component comprising at least one processor and at least one memory which are arranged to perform operations of:
identifying a scheduled temporary shutdown;
generating a shutdown anticipation message comprising information on a duration of the scheduled temporary shutdown of the monitored component;
transmitting the shutdown anticipation message to the supervisory device;
the supervisory device comprising at least one processor and at least one memory which are arranged to perform the operation of:
stopping monitoring of the monitored component for the duration of the scheduled temporary shutdown as indicated by the information on the duration of the shutdown in the shutdown anticipation message; and,
upon receipt of the shutdown anticipation message, transmitting a secondary information message to the secondary component; the secondary information message comprising the information on the duration of the shutdown of the monitored component; and,
the secondary component, upon receipt of the secondary information message, stopping the monitoring of the monitored component for the duration of the scheduled temporary shutdown as indicated by the information in the shutdown anticipation message.

7 . A land motor vehicle comprising the system as claimed in claim 6 .

8 . A method for managing a scheduled temporary shutdown of an electronic component monitored by a supervisory device, the component and the device being comprised on board a land motor vehicle, the method comprising steps of:
the component identifying a scheduled temporary shutdown; the component generating a shutdown anticipation message comprising information on a duration of the scheduled temporary shutdown of the component; the component transmitting the shutdown anticipation message to the supervisory device; the supervisory device stopping monitoring of the component for the duration of the scheduled temporary shutdown as indicated by the information on the duration of the scheduled temporary shutdown in the shutdown anticipation message; wherein the vehicle further includes a secondary component, the secondary component monitoring the operation of the component, the method further comprising the step of: the supervisory device, upon receiving the shutdown anticipation message, transmitting a secondary information message to the secondary component; the secondary information message comprising the information on the duration of the scheduled temporary shutdown of the component; and the secondary component stopping the monitoring of the component for the duration of the scheduled temporary shutdown as indicated by the information on the duration of the scheduled temporary shutdown in the shutdown anticipation message.

9 . The method according to claim 1 wherein, once the duration has elapsed, the supervisory device resumes monitoring of the monitored component.

10 . The method according to claim 3 wherein the monitored component sends the resume information message to the supervisory device prior to the end of the shutdown duration.
