Air conditioning system and audio system control device for motor vehicle, has common microcontroller for implementing both air conditioning and audio system control functions and connected to common supply source

摘要

The device has a common user interface (10) to receive commands from a user. A control unit (12) exchanges data with the user interface through a common communication bus. The control unit has a common microcontroller (120) to implement both air conditioning system and audio system control functions. The microcontroller is connected to a common supply source and is mounted on a common printed circuit board.
