The article deals with the peculiarities of processing the results of the remote control of the parameters of the technical condition of the vehicles in the operating conditions, which allows to obtain the value of average speeds for the site taking into account the geo-zone, fuel consumption and the relative coefficient of change of the speed of movement, which is the main guideline in determining the conditions of operation of cars.
In the work of determining the speed of cars in operating conditions was performed in several stages. In the first stage of the study, the process of determining the speed of the car was carried out as a whole for the whole section of the experimental section of the road. In the second stage of the study, a similar result was obtained, as in the first stage, in terms of taking into account the operating conditions of the vehicle at speed and correctly obtaining the value of the relative coefficient of change in the speed of movement. With this speed determination, it is not possible at all to determine the operating conditions of the vehicle at speed, although it is possible to determine the transport, road and weather conditions. In the third stage, to determine the speed of the vehicle, taking into account the operating conditions, the pilot section of the road was broken depending on the formation of geo-zones along the entire distance of the road. As a result, the average fuel consumption of the vehicle (for example, a segment C passenger car) over the whole distance of travel, taking into account a geo-zone equal to Gmedium = 7.23 liters/hour. On the same section of the car movement the value of the relative coefficient of change of the speed of movement
Kv p = 0,94, which belongs to the first group of operating conditions, was obtained, it varied on the sections of the road of movement within the limits of Kv p = 0,69 - 1,25.
It is determined that in the course of the study the evaluation of the results of determining the technical and economic performance and parameters of the technical condition of the vehicles in the operating conditions was carried out at the average speed of vehicles and fuel consumption. The evaluation of the operating conditions was carried out according to the value of the relative coefficient of change of speed of movement in accordance with the provisions of the theory of operation of cars. The assessment of the traffic of vehicles was carried out on one route for 3 variants with the use of geo-zones in their formation. The obtained results made it possible to improve the method of processing the results of monitoring the parameters of the technical condition of vehicles under operating conditions.
