Problems solved by technology

[0004] However, when the offline detection method is used, it can only detect the reliability and product quality of the hardware and software of the domain controller product, but cannot detect the domain controller's own failure or network communication failure during the working process; In the hardware redundancy method, it is necessary to design different hardware structures for the domain controllers of different vehicles. Although the security and reliability of the domain controllers can be improved, the structural design is complicated and the cost is high, which increases the cost of the entire vehicle.

Abstract

The invention discloses a vehicle control system and a vehicle. The system includes: two domain controllers in the same subnet domain, wherein each of the domain controllers has a different actual IP address of the Internet protocol, but each of the domain controllers uses the same virtual IP address through the vehicle Ethernet The interface is connected to the vehicle-mounted Ethernet general network; each of the domain controllers is used to monitor the working status of the corresponding active domain controller in the sub-network domain after operating as a backup domain controller in the sub-network domain, When the working state is abnormal, send an alarm prompt and replace the active domain controller as a new active domain controller. It solves the problem that the failure of the domain controller in the sub-network domain affects the function of the whole vehicle. At the same time, only the domain controller redundancy is used in the key domain of the vehicle, and there is no need to redesign the hardware structure of the domain controller, which improves the safety of the whole vehicle While improving performance and reliability, the cost of the whole vehicle is reduced.

Description

Technical field [0001] Example embodiments relate to a vehicle control system and a vehicle control a vehicle, and more particularly relates to the present invention. Background technique [0002] In recent years, the electric car, intelligent, network-linked and lighter weight direction, the electronic control unit (Electronic Control Unit, ECU) on the number of cars increases every year, the overall automotive electrical and electronic architecture tends to be complex, car often used in automobile domain controller (domain Control Unit, DCU) will be a number of different functions of the ECU chip and centralized management, formed a key node-board Ethernet backbone architecture, and security and reliability of the car to maintain the domain controller a direct impact on the safety of the vehicle. [0003] Controller Functional safety and reliability of the conventional method of protection domains primarily by internal hardware redundancy to detect and offline methods. Wherein,...
