The article describes the peculiarities of mathematical models for determining the performance indicators of operation and environmental impact of road vehicles. The models are the basis of intelligent monitoring systems for separate road transport objects: vehicle propulsion systems, separate vehicles in motion on the real route and traffic flows. The structures of these monitoring systems with the characteristics of input data, the features of simulating the main processes and output results of monitoring the performance indicators of operation and environmental impact of road vehicles are presented. The examples of current parameters monitoring of the car with a gasoline engine in three typical motion phases in the traffic flow are given.
The article describes the peculiarities of using the information and analytical system to study the operating processes of vehicle propulsion systems and to assess their environmental performance, particularly fuel consumption and harmful emissions under operating conditions. The study provides the functional structure of the information and analytical system. It contains the subsystems that enable to obtain and analyze data about the operating process in the cylinder, the subsystem for obtaining data from the engine control system, the subsystem for obtaining data about the operating mode of the propulsion system, the subsystem of data analysis and forecasting the vehicle propulsion system indicators in different operating modes. The case of using the information and analytical system has been shown to study the influence of exhaust gas recirculation on fuel efficiency and environmental performance indicators of the vehicle propulsion system in separate modes and under operating conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
