Increased active safety and connectivity content in the car will cause the number of computers on the average car to swell from 50 to 70 electronic control units within the next five years. The introduction of multi-domain controllers—a powerful control center that brings multiple electronic sub-systems together--could help lessen that burden by increasing computing power in smaller and fewer, but more powerful controllers.
These “uber brains,” or multi-domain controllers, can process massive amounts of data and manage several functions at once; unlike current domains that can only control one function at a time. Although the number of computers in the car will continue to grow as the demand for content in the car increases, we will be able to manage it with fewer computers. (Published on Dec 15, 2015)
