Abstract

The invention discloses a cloud-terminal fused intelligent drive-by-wire chassis health monitoring system and method. The system comprises a cloud data terminal and a drive-by-wire chassis terminal, wherein the drive-by-wire chassis terminal comprises a drive-by-wire driving system, a drive-by-wire steering system, a drive-by-wire braking system and a vehicle device. Whether parts are damaged or not is judged by detecting the states of key parts of the drive-by-wire chassis such as a hub motor, a steering gear, a torsion bar and a steering pull rod in real time, abnormal data are diagnosed online through the cloud data terminal, and health monitoring is conducted on damage of the automobile drive-by-wire chassis.

Description

technical field [0001] The invention belongs to the technical field of vehicle-by-wire chassis detection, and specifically relates to a cloud-terminal fusion intelligent wire-by-wire chassis health monitoring system and method. Background technique [0002] With the development of the times, the intelligentization of automobiles is the general trend. As the key to realizing intelligentization, wire control technology is gradually being applied to automobile chassis. Wire control technology has the following advantages: it provides more space for car design, and the flexibility of wire control greatly reduces the cost of car design, engineering manufacturing and production, as well as reduces maintenance requirements and body weight. However, the control-by-wire system must meet safety redundancy. Once the key parts of the system, such as motors, sensors, and ECUs, fail and are damaged during driving, it will seriously affect the safety of the vehicle and endanger the safety ...
