Zusammenfassung:	An on-board vehicle computer system receives a software update package from a remote computer system via a wireless communication network. The update package includes a software update for an updatable electronic component (e.g., an ECU) of the vehicle. Prior to installing the update, the vehicle computer system may check for a valid backup software version in a storage medium in the vehicle computer system to facilitate reversion to a previous software version in the event of an error during installation of the update. Installation of the update may be delayed until a compatible backup software version is obtained. After installation of the update, the system stores the update in the storage medium as the current backup software version for the updatable electronic component. This facilitates roll-back to a functional state in the event of an error during a future update.
