FIELD: computer technology.
SUBSTANCE: invention relates to the field of computer technology. The expected result is achieved due to the fact that the device contains a display, processor and memory containing a program that performs the following steps: determining the current position and speed of the vehicle on the section of the road within a pre-formed energy-efficient track, and the track contains the estimated position and estimated speed of movement on the section of the path; comparing the current speed of the vehicle with the estimated speed of movement; formation of a control signal for displaying graphic elements corresponding to the coincidence or discrepancy of the current speed of movement with the mentioned design speed.
EFFECT: reduction in the vehicle’s energy consumption on a specific section of the track, as well as providing the ability to control the vehicle’s energy consumption and improving the accuracy of providing information about the vehicle’s energy consumption.
