Abstract

The invention relates to a plug-and-play smart vehicle domain controller with a redundant structure and a method. The domain controller is provided with a power supply redundancy structure, a microcontroller redundancy structure, a microprocessor redundancy structure, a communication redundancy structure, a data redundancy structure and a redundancy management module through a hardware redundancymethod. The microcontroller redundancy structure comprises more than two microcontroller MCUs which realize intelligent control and an auxiliary chip. The microprocessor redundancy structure is a multi-embedded microprocessor structure. The communication redundancy comprises multiple redundant buses. The data redundancy structure comprises more than two data storage units. The redundancy management module is used to isolate, switch and reconstruct input and output channels and signals of the domain controller when faults or attacks are discovered. The domain controller is connected with the whole vehicle to complete safe deployment, and is suitable for smart vehicles of the L3 class and above or link smart vehicles. Compared with the prior art, the domain controller provided by the invention has the advantages of high security, high reliability, high adaptability, good cross-platform versatility and the like.

Description

technical field [0001] The invention relates to a domain controller in the field of smart cars, in particular to a plug-and-play smart car domain controller with a redundant structure and a method. Background technique [0002] In recent years, thanks to the continuous major breakthroughs in information technology, the automobile industry has entered the information age, and automobile products are gradually becoming intelligent and networked. my country is vigorously promoting the development of smart cars and connected smart cars, especially the development of smart transportation and the Internet of Things, which is constantly promoting the development of the Internet of Vehicles with cars as nodes, and the information interaction between cars and the outside world will become more frequent and complex. However, in the process of information interaction, external attacks or implanted malicious Trojan horse viruses will destroy the electronic control system of the car, whi...
