This paper investigates and proposes the possibilities of standardizing the software/firmware package format and flash jobs in order to provide the possibility of productizing the update-over-the-air solution regarding on-board vehicle components and make use of it in all OEMs with minimum configuration changes and customization. The update-over-the-air solution in the automotive sector is provided by various suppliers and needs to be customized to meet various OEMs requirements. Possible Variants of OEM requirements are: • Variant 1 o Customer Portal + Backend + vehicle on-board components solution from supplier • Variant 2 o Customer Portal + Backend solution from OEM o Vehicle on-board components from supplier • Variant 3 o Backend from OEM o Customer Portal + vehicle on-board components from supplier ODX, VBF, and many other formats from OEMs include software/firmware packages. With variant 1, these different formats are converted into one supplier proprietary format and is saved in backend and understood by the vehicle on-board components for re-programming of target ECUs. With variant 2 and variant 3, these different OEM formats have to be processed by the vehicle on-board components, which results into continuous customization of the vehicle on-board components on various OEM requests and cannot act as single solution for all OEMs. Standardizing the software/firmware package and flash job format between backend and vehicle on-board components results into the vehicle on-board components as a product with minimum customization via configuration across OEMs in the automotive sector.
