FIELD: test technology.
SUBSTANCE: invention relates to testing of machines. In method for determination of vehicle tractive power at starting from partial load mode, means are connected to tractive device, starting from partial load mode and determining value of tractive power. Tractive power of tested device is determined from engine crankshaft rotation frequency in partial load mode at preset thrust force at full fuel supply. For given force, engine crankshaft maximum rotation speed is first found, having nominal tractive power, and engine crankshaft minimum rotation speed, having tractive power, which corresponds to power developed at specified partial load. Then, engine crankshaft rotation speed is measured to determine tractive power of vehicle by formula.
EFFECT: higher quality of determination.
