Abstract

A method of designing a domain controller for a vehicle, a domain controller, and a vehicle are provided. The design method includes: installing an operating system on the domain controller; installing a program of a vehicle-mounted communication terminal (T-BOX) of the vehicle in the operating system; configuring a virtual machine in the operating system; and A vehicle controller (VCU) real-time operating system of the vehicle and a software program for the vehicle controller are installed in the virtual machine, wherein the software program for the vehicle controller runs on the vehicle controller real-time operating system. The present invention does not need to deploy interactive wire harness connections, which can simplify design, reduce hardware and labor costs, and reduce space occupation. The domain controller of the present invention communicates through a virtual network, thereby reducing the CAN communication load rate, and the domain controller of the present invention The controller includes all the functions of the vehicle communication terminal and the vehicle controller to achieve real-time and stable effects.

Description

technical field [0001] The present invention relates to the field of domain controllers of vehicles, and in particular, to a design method of a domain controller for vehicles, a domain controller and a vehicle. Background technique [0002] With the gradual improvement of the electronic degree of the vehicle, more electronic control units (ECUs) are usually installed on the vehicle to realize corresponding control functions in different aspects, such as anti-lock braking system, four-wheel drive system, electronic control Automatic transmission, active suspension system, airbag system, and gradually extended to body safety, network, entertainment, sensor control system and so on. These ECU controllers are connected by a bus, and information is exchanged through a communication protocol preset by engineers. With the increasing electronic and intelligent degree of vehicles, the number of electronic control units is still increasing year by year, and the bus length is also inc...
