Abstract

The invention discloses a digital twin-driven intelligent drive-by-wire chassis system and a fault diagnosis method thereof. The digital twin-driven intelligent drive-by-wire chassis system comprises a drive-by-wire chassis device, a drive-by-wire chassis digital twin system and a cloud platform, the cloud platform is in data connection with the drive-by-wire chassis device and the drive-by-wire chassis digital twin system in a communication network mode. The drive-by-wire chassis device comprises a drive-by-wire steering system, a drive-by-wire braking system and a drive-by-wire driving system. The three complete corresponding steering, braking and driving actions according to a control instruction; the digital twinning system of the drive-by-wire chassis device is generated through the digital twinning technology, the digital twinning system and the drive-by-wire chassis physical entity run consistently through the data driving method, and the real-time interaction of data of the drive-by-wire chassis device and the digital twinning system is achieved.

Description

technical field [0001] The invention belongs to the technical field of fault diagnosis of a control-by-wire chassis, and specifically refers to an intelligent control-by-wire chassis system driven by a digital twin and a fault diagnosis method thereof. Background technique [0002] Nowadays, with the development of automobile intelligence and electrification, wire control technology is widely favored. Compared with the traditional chassis, which is controlled by mechanical and hydraulic systems, the control-by-wire chassis technology has the advantages of high control accuracy, but the control-by-wire chassis mainly controls the vehicle through electrical components such as batteries, motors, sensors, controllers, and wires. Once the power is insufficient or the electrical components If a fault occurs, the controllability of the chassis by wire system will be greatly reduced or even out of control, causing serious safety hazards. Moreover, the driving environment of the car ...
