Document Type and Number:
WIPO Patent Application WO/2021/002164
Kind Code:
A1
Abstract:
The present disclosure relates to operating Electronic Control Units (ECUs) of a vehicle in a fail-safe mode. The vehicle is controlled by a control system comprising a plurality of primary ECUs and a plurality of back-up ECUs backing-up the plurality of primary ECUs. Each back-up ECU comprises a migration map comprising a list of the plurality of back-up ECUs and corresponding primary ECU. The migration map may be shared between each other ECU from the plurality of back-up ECUs. Each ECU is configured to update the migration map based on availability of back-up ECU for corresponding primary ECU. If unavailable or if any failure of any back-up ECU, the migration map is updated, and new back-up ECU is determined in place of unavailable/ failure back-up ECU. The updated migration map is used by the plurality of back-up ECUs for determining the updated back-up ECUs.
