Let's take a hard look at Tesla's zone controllers from Model 3 to Model Y -- it's been iterated from generation 1 to Generation 3.
From a compatibility point of view, the three controllers have always maintained forward compatibility on the interface, but the internal function allocation is really iterating.
As a contrast, in general, if the three Zonal are done by other car companies, it will generally be divided into the door module, integrated body controller, seat controller, thermal management controller HVAC and front-end cooling controller Theraml Unit and parking controller. There are so many lighting controls, interior lights may be separately divided into a controller to do.
From the perspective of control structure, the three regional controllers can be distributed to do, can also do some top-level applications on the main information system, to achieve the control of a system.
