The new cyber-technological culture of the transport control based on virtual road signs and streetlight signals on the screen of car is the future of Humanity. A cyber-physical system (CPS) Smart Cloud Traffic Control, which realizes the mentioned culture, is proposed; it is characterized by the presence of the digitized regulatory rules, vehicles, infrastructure components, and also accurate monitoring, active cloud streetlight-free cyber control of road users, traffic lights, automatic output of operational regulatory actions (virtual traffic signs and traffic signals) to monitor of each vehicle. The main components of the cyber-physical system are the following: infrastructure, road users and rules, which have digital representation in cyberspace to realize a route, based on digital monitoring and cloud mobile control.

Remote monitoring is the most important stage in controlling the technical condition of a modern vehicle under operating conditions. Remote control of the technical condition involves using V2I systems in order to form and apply individual maintenance and repair systems. V2I information model developed in the article is characterized by vehicle digital field, limited by regulatory rules, with means for technical condition parameters monitoring and components of infrastructure for each vehicle monitoring. The article describes the peculiarities of V2I information system and the process of monitoring and evaluating the vehicle technical condition under operating conditions with the possibility of forecasting. The monitoring information system is designed to ensure the vehicle efficient operation under non-stationary operating conditions, with continuous consideration of information from road and transport infrastructure.

Diagnosis of the car is a necessary means for early detection of developing malfunctions. A technique for diagnosing on a short road based on the acceleration in the second and third gears and coasting from 50 or 40 to 20 km/h is proposed. The results should be compared with the reference values calculated, taking into consideration the speed rolling resistance dependence, described by the square trinomial, the speed air resistance dependence with the variable exponent, the losses of the transmission idling mode and the progressive total resistances decrease at speeds below 25 km/h. The general speed dependence of the total resistance is described by a sixth-degree polynomial but not the second-degree one, as many researchers believe. The experimental check was performed on a subcompact sedan with 1.6 atmo engine. Weight of 1370 kg. First class road with an average rise of 0.0182, asphalt in good condition. There was no wind.

The article discusses the features of applying vehicular engine heating system with phase-transitional thermal accumulator. The peculiarity of the presented system is that it uses thermal energy of exhaust gases from internal combustion engine during its operation to accumulate heat. The results of experimental studies of heating the vehicular engine are shown. The article describes the structure of information package for studying the internal combustion engine of a vehicle with heating system and thermal accumulator during the start and after-start heating. The package allows engine performance parameters and engine thermal development to be estimated from distance within intelligent transport systems. Using phase-transitional thermal accumulator in engine coolant heater system (case studied: G4GC (4FS 8.2 / 9.35) of KIA CEE'D 2.0 5MT2) reduces time for heating by 17.8 - 68.4% and fuel consumption by 19.5 - 56.25%.
