Prerequisites for the creation of domestic onboard diagnostics tools for the M1 and M2 categories vehicles

Abstract

BACKGROUND: Due to the steady growth of the worldwide fleet of vehicles alongside the sophistication of their operational functions and the increase in the number and manufacturability of electronic control units, used in a vehicle, the demand for means of access to the performance of on-board electronic sys-tems at the final stages of their production and operation is increasing. This review is necessary to summarize the available data from the world experience in the development and implementation of on-board diagnostic systems.

AIMS: Formulation of general principles for the development of on–board diagnostic systems, helpful to outline reasonable technical solutions for the task of creation of proprietary domestic diagnostic environment for vehicles.

METHODS: This paper describes the purpose and role of onboard diagnostic systems used in world practice for modern vehicles. Classes of diagnostic devices are allocated according to the level of implemented functions. The grounds that determine the demand for development of proprietary onboard diagnostic systems for wheeled vehicles are considered. A review of the functionality of the original diagnostic tools of foreign vehicle manufacturers was carried out. The main requirements imposed on developers by the ISO 27145 and ISO 14229 group of standards within the framework of the implementation of modern diagnostic systems in domestic vehicles of the M1 and M2 categories are determined.

RESULTS: A specific set of functions recommended for integration into diagnostic equipment being developed as a part of promising domestic developments has been determined. The content of the positive effect of the practical implementation of the measures proposed according to the results of the analysis is formulated.

CONCLUSIONS: The performed scientific analysis of the features of the existing diagnostic equipment is helpful to determine the relevant trends in the implementation of a fundamentally new trend in on-board diagnostics in the Russian Federation, which contributes to increasing the level of competence of domestic specialists and development within the framework of the domestic engineering development strategy.
