Location 

The OLU communication module and OLU central computer are located in the seat base of the front passenger seat.

Task 

The OLU is a Linux-kernel-based, high-performance vehicle control unit that is connected to the Internet.

The OLU abstracts vehicle functions to a higher abstraction interface and is connected to the actual vehicle through various interfaces.

Among other things, the OLU enables transport companies to optimize and expand existing areas of activity, and to open up new areas of activity.

Together with modern sensor systems and data analysis, the combination of modern hardware and software ensures that the vehicle is used in a flexible manner. Fleet managers and drivers benefit equally from the OLU interface.
