Description

FIELD OF INVENTION The proposed invention relates to methods for controlling energy consumption by a motor vehicle, and can be used in transportation industry. BACKGROUND OF THE INVENTION There is a known method for evaluating the fuel efficiency of a motor vehicle disclosed in patent KR101526431B1, published on 06.05.2015 on 12 sheets (D1). The method of D1 is implemented by a device for evaluating the fuel efficiency of a motor vehicle, the device comprising: a data collection unit that collects data on driving, as well status and identification data of a plurality of motor vehicles, including the first motor vehicle; a driving index calculator that calculates driving indexes of each motor vehicle based on their driving data; a means for extracting an analogous group that extracts a group of motor vehicles, which are similar to the first motor vehicle, from a plurality of motor vehicles, based on their driving indexes and status data; a means for fuel efficiency evaluation that evaluates the fuel efficiency of the first motor vehicle based on its driving data and identification data in the analogous group; and a means for controlling a motor vehicle that controls the method of steering the motor vehicle or the method for improving the driving of the first motor vehicle, based on the fuel efficiency evaluation. According to the invention, the fuel efficiency of a motor vehicle can be evaluated with precision taking into account driver's habits and the current condition of the vehicle. In addition, the method of steering the motor vehicle and the driving mode based on the assessment of the vehicle's fuel are provided to the driver, so that he/she can improve his/her driving efficiency and the efficiency of steering the motor vehicle, as well as reduce the cost of vehicle maintenance. The method disclosed in D1 does not use the information on the specific portion of the route that was covered by the first motor vehicle, which reduces the accuracy of fuel consumption estimation. In addition, the method disclosed in D1 uses the information obtained from motor vehicles with similar specifications and similar driving mode only, which prevents the method from being used in a global fuel consumption control system comprising multiple motor vehicles with different specifications. In addition, the method disclosed in D1 is used to identify operational problems of motor vehicles that affect the fuel consumption levels and require certain vehicle parts to be repaired or replaced, and so this method cannot be used to change the motor vehicle driving mode in order to reduce the energy consumption on a given portion of the route. In addition, the solution disclosed in D1 does not propose any specific or special means or methods to generate a model of the motor vehicle moving in an urban area, resulting from other motor vehicles moving along trajectories located on corresponding portions of the route, actual or estimated presence of other motor vehicles, including on other portions of the route. The method disclosed in D1 can be considered the closest prior art to the claimed invention. Document GB 2 567 008 A discloses a method for generating an adjustment energy-efficient track for a vehicle in operation, that is performed by a computer's CPU. BRIEF SUMMARY OF THE INVENTION The technical problem to be solved by the claimed invention is to provide a method, a device and a non-transitory computer-readable medium that do not possess the drawbacks of the prior art and thus make it possible to generate an accurate energy-efficient track for a motor vehicle that allows to reduce energy consumption by the motor vehicle moving along a portion of the route in an urban area taking into account other vehicles' trajectories. The objective of the claimed invention is to overcome the drawbacks of the prior art and thus to reduce energy consumption by the motor vehicle moving along a portion of the route in an urban area taking into account other vehicles' trajectories, as well as to improve traffic safety. The objective of the present invention is achieved by a method according to claim 1, by a device according to claim 12 and a medium according to claim 14.
