Abstract

PURPOSE:To obtain the set value of good accuracy in a short time without setting mechanical losses by performing the setting of traveling resistance having mechanical loss compensating power automatically. CONSTITUTION:A traveling resistance command part 20 sets the absorption torque of a driving power absorber according to traveling speeds in conformity with the actual traveling resistance. A setting operating part 23 operates the actual traveling resistance from the time measurement data in each speed section in coasting on roads. In an automatic discrimination part 24, traveling resistances are operated by the time measurement of each speed section in the coasting test with a dynamometer, and the coincidence thereof with the results of operations in the part 23 is decided. When the coincidence decision is not obtained, a correction operating part 25 corrects the traveling resistance and applies the fresh set value of the part 20. The set value for the traveling resistance including mechanical losses is obtained by repeating the automatic decision and correction until the coincidence decision is obtained in this way.
