Information control and diagnostic systems of modern vehicles

Abstract

Problem. The article analyzes displays and work units that communicate with all connected components through the on-board communication controller to control and display information on the display. Particular attention is paid to control and measuring devices and on-board diagnostics, information systems of hybrid vehicles. Goal. The object of research is the process of analyzing the functionality of information control and diagnostic systems. The purpose of the study is to increase the competitiveness of vehicles by expanding the functionality of information systems. Methodology. The research method is based on the use of a systematic approach to the analysis and synthesis of information vehicles, on the rational combination of theoretical and experimental developments and the generalization of scientific results. Results. The basic functions of most vehicle combinations are the same, although some functional units, including microcontrollers, program-based storage integrated circuits, and standard external devices, sometimes differ significantly. Leading companies that produce modern automotive and tractor equipment, currently use extensive microprocessor on-board control systems that monitor the condition of the battery, clutch, shock absorbers, compression in the cylinders of the ignition system, etc. Features of information systems of hybrid vehicles are that in them the function of the assistant with recommendations to the driver concerning fuel saving is realized. Practical value. The information control and diagnostic systems of modern vehicles are considered. Particular attention is paid to instrumentation and onboard diagnostics, information systems of hybrid vehicles. The information systems Honda CR-Z and Chevrolet Volt are shown.Key words: vehicle, information system, control and diagnostic systems, measuring instruments, on-board diagnostics
