Zone controller and whole vehicle electrical architecture

Abstract

The invention provides a zone controller. The zone controller comprises a micro-control unit, a micro-processing unit and a special integrated circuit unit, wherein the micro-control unit is used for processing control information of a vehicle body domain, a power domain and a chassis domain; the micro-processing unit is used for processing control information of an infotainment domain; the special integrated circuit unit is used for processing control information of an intelligent driving domain; and the micro-control unit is in communication connection with the micro-processing unit and the special integrated circuit unit. The micro-processing unit is in communication connection with the special integrated circuit unit, the zone controller is arranged in a control zone of a whole vehicle, the number of wire harnesses in the whole vehicle can be remarkably reduced while the control sensitivity of the vehicle is guaranteed, the development period of control software is shortened, the development cost is reduced, and maintenance and upgrading of the vehicle are facilitated.

Description

technical field [0001] The embodiments of the present application relate to the technical field of automobiles, and in particular to a zone controller and a vehicle electrical architecture. Background technique [0002] With the development of the automobile industry, the configuration of electronic appliances in the vehicle is becoming more and more abundant, which has led to a gradual increase in the number of controllers, sensors and actuators mounted on the vehicle, and the increase in the number of controllers has brought The increase in the number of wiring harnesses and the number of communication signals, due to the higher and higher requirements for control sensitivity in today's automobiles, the requirements for communication speed between electronic appliances such as controllers, sensors and actuators on vehicles are also getting higher and higher. At present, in the automotive field, in order to improve the communication speed between electronic and electrical c...

[0002] With the development of the automobile industry, the configuration of electronic appliances in the vehicle is becoming more and more abundant, which has led to a gradual increase in the number of controllers, sensors and actuators mounted on the vehicle, and the increase in the number of controllers has brought The increase in the number of wiring harnesses and the number of communication signals, due to the higher and higher requirements for control sensitivity in today's automobiles, the requirements for communication speed between electronic appliances such as controllers, sensors and actuators on vehicles are also getting higher and higher. At present, in the automotive field, in order to improve the communication speed between electronic and electrical components, a vehicle electrical architecture divided according to functional domains is generally used. This vehicle electronic architecture based on domain controllers, because different sensors and actuators of the vehicle are located in The different positions of the car body lead to a large number of controllers, a large number and long wiring harnesses of the vehicle, a long software development cycle, and difficult maintenance of software and hardware
