Embodiment

[0036] figure 1 It is a specific implementation flow chart of the fault diagnosis method of the networked vehicle control system of the present invention. Such as figure 1 As shown, the specific steps of the fault diagnosis method of the networked vehicle control system of the present invention include:

[0037] S101: Layering of connected vehicle control system:

[0038] The networked vehicle control system is divided into a control layer and an information layer. figure 2 It is a layered schematic diagram of the vehicle control system of China Internet of Things in the present invention. Such as figure 2 As shown, the control nodes in the control layer are the nodes that realize the control function in the connected vehicle control system, and the remaining nodes are divided into the information layer as information nodes, and the information nodes in the information layer are controlled by the control nodes in the control layer.

[0039] Generally speaking, the infor...

Abstract

The invention discloses a fault diagnosis method for a networked vehicle control system, which divides the networked vehicle control system into an information layer and a control layer, wherein the information layer uses genetic particle swarm filtering to estimate the output state parameters of information nodes, and calculates and Fault diagnosis is carried out based on the residual of the actual output state parameters; the control layer uses a multi-layer expanded state observer to estimate the output state parameters of the control nodes, calculates the residual with the actual output state parameters, and performs fault diagnosis based on this. The invention provides a brand-new fault diagnosis method for the networked vehicle control system, and provides technical guarantee for the safe operation of the networked vehicle control system.

Description

technical field [0001] The invention belongs to the technical field of networked vehicle control, and more specifically relates to a fault diagnosis method for a networked vehicle control system. Background technique [0002] Cars with networking, intelligence and electrification are regarded as an important direction for future car development. In 2017, the State Council issued my country's "New Generation Artificial Intelligence Development Plan", which clearly put forward the development requirements for a new generation of intelligent networked vehicles. The National Development and Reform Commission drafted the "Smart Vehicle Innovation and Development Strategy" in January 2018 after soliciting opinions from the society. It can be seen that intelligent networked vehicles have become an emerging strategy of the country. [0003] The intelligent networked car is also a complex information-physical fusion system (Cyber ​​physical systems, CPS) with multiple information s...
