METHOD FOR DETERMINING VEHICLE EFFICIENCY

The article proposes an experimental methodology, which is based on a new approach to estimating the coefficient of performance (COP) of a car in the “power plant - transmission” part, as a system consisting of a subsystem. Each of the selected subsystems has its own efficiency size and affects the resulting value to varying degrees. The results of testing the effectiveness of the method were obtained using comparative results of calculated and experimental efficiency on car models, the absolute error of which does not exceed 1.5%.
