Some context for those wondering: A few years back, Continental bought the Siemens VDO Automotive business unit from Siemens. Siemens had been powering the dashboard and computing units of several auto companies, which is now owned by Continental.
It's interesting to see how the corporate alliances are shaking out. Bosch is supplying hardware for BMW and Daimler-Mercedes self driving efforts... not sure who is behind Volkswagen Audi Group's efforts, as Stanford's efforts seem to be off the shelf components (LiDAR and such).
I couldn't find anything about IBM working specifically on self-driving cars, but given their work on AI (people haven't forgotten about Watson already, have they?), it seems only natural that they would have a lot to bring to the table.
