Controller system and control method

This application relates to the field of intelligent vehicle technologies in the field of artificial intelligence technologies, and in particular, to a controller system. The controller system includes: an intelligent driving domain control unit; a human-machine interaction domain control unit; and a sensor interface unit that is connected to the intelligent driving domain control unit and the human-machine interaction domain control unit. The sensor interface unit is connected to a sensor, and transmit data of the sensor to the intelligent driving domain control unit and the human-machine interaction domain control unit. In this application, external cable connections can be simplified, occupation of data stream transfer resources can be reduced, and power consumption of a vehicle can be reduced.
