Automobile network control system

Abstract

The invention provides an automobile network control system. The automobile network control system comprises a front-end controller, a rear-end controller, a driving controller and a plurality of networked sensors. Each of the front-end controller and the rear-end controller comprises a computing unit and a communication unit; the front-end controller is connected with the networked sensor arranged in a first area range through the communication unit; the rear-end controller is connected with the networked sensor arranged in a second area range through the communication unit; the front-end controller and the rear-end controller are in communication connection through the communication unit; the computing unit performs vehicle control according to the information received by the communication unit of the controller to which the computing unit belongs; and the front-end controller and the rear-end controller are connected with the driving controller through the communication units. By arranging the regionalized controller, the wiring length of the whole vehicle can be reduced, and meanwhile, the communication unit and the calculation unit in the controller are separately arranged sothat the stability of the system is improved.

Description

technical field [0001] The present application relates to the field of electrical and electronic architecture, in particular to an automobile network control system. Background technique [0002] Electrical / Electronic Architecture (EEA) is to integrate all kinds of sensors, central processing unit, wiring harness topology, electronic and electrical distribution system and other software and hardware in the car to realize the configuration and function of the whole vehicle, as well as computing and power. , Energy distribution. The traditional distributed electronic and electrical architecture is difficult to carry the complex functions of the car, which greatly affects the user experience. Taking the traditional automotive supply chain as an example, vehicle manufacturers are highly dependent on the ECU (Electronic Control Unit, electronic control unit, also called "driving computer") provided by the first-tier component suppliers, but different ECUs come from different sup...

Problems solved by technology

This coaxial cable solution has the following problems: the communication method is a private standard, and the manufacturers cannot communicate with each other; the cameras can only be connected point-to-point with the domain controller, so that the cameras around the car body need to be connected to the central controller, resulting in The length of the cable is large; the video data of the camera can only be provided to a domain controller, but cannot be shared with the controller, resulting in an increase in cost

[0007] Lack of equipment redundancy design to ensure the functional safety of the system. For example, in Tesla's "regional zone" solution, the central computing module uses a serial circuit to share visual data, and the serial processing method increases the risk of system failure. Probability, once the system fails, due to the lack of equipment redundancy, the central computing module will no longer be able to share visual data through the serial circuit, posing certain security risks
