An intelligent control-by-wire chassis system driven by a digital twin and its fault diagnosis method

Abstract

The invention discloses an intelligent control-by-wire chassis system driven by a digital twin and a fault diagnosis method thereof, comprising: a control-by-wire chassis device, a digital twin system of a control-by-wire chassis and a cloud platform; The chassis digital twin system is connected through a communication network; the chassis control-by-wire device includes: a steering-by-wire system, a brake-by-wire system, and a drive-by-wire system; the three complete corresponding steering, braking, and driving actions according to control instructions The present invention generates the digital twin system of the control-by-wire chassis device through the digital twin technology, utilizes the method of data drive, makes the digital twin system and the physical entity operation of the control-by-wire chassis consistent, and realizes the real-time data of the control-by-wire chassis device and the digital twin system interact.

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 ...
