Research on the method of coasting resistance for light-duty vehicles at various altitudes

Abstract

In order to obtain the coasting resistance of vehicles at different altitudes and temperatures, experiment selects three different types of vehicles, and conducts altitude coasting resistance research tests at four altitudes and temperatures. The results show that the modified coasting resistance method can accurately correct the coasting resistance of the vehicle under the condition of 0 meters and 20 °C to different altitudes and temperatures, while the error is controlled within 6%.The modified coasting resistance method can be kept within 4% in most cases, and it is applicable to different types of vehicles.
