TESTING EQUIPMENT FOR CAR PARTS

摘要

PROBLEM TO BE SOLVED: To solve the problem that highly accurate and responsive control is difficult because a temperature drift is generated in a torque meter when a dynamometer is controlled by the detection of the torque of a torque meter. SOLUTION: The temperature of the torque meter 8 is detected other than the torque detection signal from the torque meter 8. A temperature drift map preliminarily measuring the temperature drift characteristics of the torque meter is prepared in an engine torque correction part 13 and the torque detection value due to the temperature drift is corrected. Further, a table preliminarily measuring temperature-rated torque characteristics is prepared and the torque detection value is corrected on the basis of the ratio of the temperature-rated torque characteristics to obtain the torque detection signal to a controller.
