Constructing software delta updates for vehicle ECU software and abnormality detection based on toolchain

摘要

Disclosed embodiments relate to generating an update package for updating software on an Electronic Control Unit (ECU) in a vehicle. Operations may include accessing a plurality of attributes of a software update to be stored on the ECU in the vehicle; accessing a corresponding plurality of attributes of current software stored on the ECU in the vehicle; comparing the plurality of attributes with the corresponding plurality of attributes; generating a delta file representing differences between the plurality of attributes and the corresponding plurality of attributes determined in the comparison; and providing the delta file to the ECU, wherein the delta file is configured to be processed by startup code in the ECU that enables the delta file to execute in the ECU in the vehicle.
