Abstract

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 withthe 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 536,767, filed July 25, 2017, and U.S. Provisional Patent Application No. 62 / 560,224, filed September 19, 2017, the entire contents of which are incorporated by reference into this article. Background technique [0003] Modern vehicles utilize many Electronic Control Units (ECUs) to control the operation of components such as the engine, driveline, transmission, brakes, suspension, in-vehicle entertainment system, communication system, and more. ECUs control the basic operation of modern vehicles from power steering to braking to acceleration. In addition, the ECU controls many additional functions and analysis functions in the vehicle. For example, some cars may be equipped with ECUs configured to collect and analyze driving data, which can be provided to insurance companies to determine insurance premiums. Some cars may be equipped with E...
