Justification of integrated reliability index of vehicles

Abstract

In modern automobile transport, the methodology of probabilistic estimates of the time between failures of automobiles, which has been developed over decades, is not used, and manufacturers do not include data on their reliability in the characteristics of automobiles. With their distribution of cars on flights and routes, the motor transport enterprises do not calculate the margin of their performance before repair or maintenance. The aim of this work is to substantiate automation methods for a comprehensive reliability assessment of a car and determine the residual life before setting up for repair or maintenance. It is proposed to use for these purposes statistical estimates of the operating time parameter between statements for repair or maintenance and their change as the vehicle develops a resource. A new service for the on-board local area network of vehicle has been developed to automatically monitor the performance margin. It is based on a joint automatic control of statements for repair or maintenance and calculation of vehicle operating time between them. The proposed control is intended to be implemented by means of the on-board local area network of the car and the information system for supporting the technical operation of cars at the motor transport enterprise.
