Abstract
PURPOSE:To obtain the set value of good accuracy in a short time by setting mechanical loss and traveling resistance automatically, and deciding the justness of basic data. CONSTITUTION:A mechanical loss detection part 22 detects the mechanical losses in respective speed sections from the torque detected value of a torque meter 5, and applies these as set values to a mechanical loss command part 21. A data collecting part 24 collects the data of the absorption torque and braking force torque from the meter 5 for the respective speeds with respect to >=3 points out of the respective speed of the basic data. These data are inputted to a coordinate operating part 25, by which the constant term A, primary term B, secondary term C of traveling distance are calculated, and are applied to an automatic discrimination part 26 which discriminates the justness of the contants. When the justness is admitted, a coordinate making part 28 makes the table of the traveling resistance value F at each speed V by using the constants A, B, C, and stores this in a traveling resistance command part 20. The traveling resistance table made in this way is used as the set value for the part 20, and the traveling performance is measured by the traveling resistance control corresponding to speeds.
