The Siemens In-Vehicle Software Management system addressed and solved the increasing number of vehicle variations that manufacturers face with the growth of distributive electronic systems. As the number of electronic control units expands, then lines of software code and interdependencies between competing suppliers within vehicles expands. The current number of lines of code is about 10 million in a typical vehicle. By 2015, 100 million lines of code will be within "connected vehicle." Siemens and Ford have created a software management system permitting them to monitor every vehicle variation on a global basis down to the VIN (vehicle identification number). This innovation extends the lifetime control Ford has of its global fleet by leveraging existing software management processes that also maintain security protocols for firewalls between competing suppliers to all model types.
