The concept of determining the residual life of vehicle assemblies and components

Abstract

Determining the residual life of vehicle assemblies and components is necessary to solve current problems of automobile transport: transition to maintenance (MOT) based on technical condition, development of a built-in diagnostic system, remote monitoring of the technical condition of vehicles. The improved design and high level of quality of modern cars would allow maintenance to be carried out more frequently than required by regulations. However, in order to make a decision on increasing the frequency, it is necessary to assess the actual technical condition of units and components and predict their residual life. Work is underway in the domestic automotive industry and abroad to create unmanned vehicles. In the absence of a driver, technical condition monitoring can only be performed using the built-in diagnostic system. The system must warn about the approaching limit state and take appropriate measures to prevent an emergency. The embedded system should be based on determining the current technical condition and estimating the remaining life using diagnostic parameters. One of the important tasks when assessing the technical condition and determining the residual life is to establish the relationship between structural and diagnostic parameters.
