Abstract

The invention discloses a vehicle internal resistance testing method. Sliding tests are respectively performed on a whole vehicle and all detached parts on a chassis dynamometer under different working conditions, and thus the internal resistor value of the whole vehicle and the resistor values of all part systems such as a braking system, a transmission system, a speed changing box and a main speed reducer in states corresponding to various working conditions are obtained. The vehicle internal resistance testing method has the advantages of being high in university, high in precision, low in cost and short in testing cycle.

Description

technical field [0001] The invention relates to a method for testing vehicle performance parameters, in particular to a method for testing vehicle internal resistance. Background technique [0002] The internal resistance of the vehicle is the internal resistance of the vehicle itself. It is mainly divided into two parts: the braking system and the transmission system. The internal resistance of the vehicle affects the performance and efficiency of the transmission system of the vehicle, and affects the fuel consumption of the vehicle. With the gradual improvement of the country's requirements on vehicle emissions, it is increasingly important to reduce vehicle resistance and improve transmission efficiency. [0003] At present, the current technical standards in the automotive industry usually use the vehicle sliding method to obtain the vehicle sliding distance under the condition of the vehicle road, and use the length of the sliding distance as the standard for evaluatin...
