Behind the efficiency and clean operation of modern vehicles is a steadily growing number of powertrain functions that are based on precise sensor readings, subsequently coordinated operation and electronically controlled optimization. Together with the increasing level of inter-domain networking this has led to a great many electronic control units (ECUs). The downside of this complex and rigid architecture includes added cost and additional weight – none of which is welcome.

This is why Vitesco Technologies is developing a solution for a new approach to the electric and electronic architecture (E/E architecture). One key element of this is to consider the requirements posed by the rapidly growing software share. Therefore, the new Master Controller hardware is already being made to fit the software needs. The Master Controller – instead of many individual ECUs – provides everything a vehicle needs to drive. Similar to a PC, it manages the complexity of many functions within a single architecture that is much easier to integrate into a vehicle. Also, parts of the software can be updated individually and independent of each other – very much like smartphone apps – and even completely new functions can be added after the end of the line without a visit to the workshop.
