Abstract
A method of updating Electronic Control Units (ECUs) of vehicles using updates received via Vehicle to Vehicle (V2V) communication channels comprising receiving from nearby vehicle(s) via V2V communication channel(s), one or more of a plurality of update packages distributed for updating a plurality of ECUs deployed in a plurality of vehicles, each of the nearby vehicle(s) is within a reception area of the V2V communication channel(s), analyzing an identifier extracted from each update package to determine whether the update package is directed to ECU(s) of the vehicle, communicating via the V2V communication channel(s), in case of positive determination, with a subset of the vehicles each maintaining a local log associating each update package with a respective verification code to validate the verification code extracted from the update package according to a consensus of the subset and, in case of successful validation, initiating update of the ECU(s) using the update package(s).
