Abstract
The article describes the information system for remote monitoring and control of vehicle technical condition and motion modes with the use of modern telematics technologies. There are 17 morphological features in the system, which determine the level of telematic support of the main functional elements of the system to obtain information about vehicle technical condition and motion modes in the appropriate infrastructural conditions. The information model of the system for monitoring of parameters of vehicle technical condition, motion modes and infrastructural characteristics was built. This model is implemented in the information and software complex for remote monitoring of vehicle operational efficiency. The results of experimental studies of freight vehicle operational efficiency on a given route with use of the developed information and software complex are presented. The results show significant influence of the vehicle technical speed and average coolant temperature of its engine on operational efficiency indicators such as fuel consumption, carbon dioxide, nitrogen oxides and particulate matter emissions on the route characterized by different road height profiles.
