The system would use knobs, sliders, touchscreen controls and other stuff that’s essentially present in current in-car systems, but extends its ability to be completely user programmable and able to extend its reach to systems like windshield wiper control. The patent talks about customizability through apps and information, such as from the Stocks app, being displayed through the console.
The patent filing itself is an older one, but Apple is just now starting to really make its intentions known regarding how it will begin to expand in this new market.
