Title:
TRANSMISSION TESTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/035310
Kind Code:
A1
Abstract:
[Problem] Provided is a transmission testing device that can highly accurately reproduce the behavior of an actual engine. [Solution] The present invention has: a drive dynamometer DM1 that is connected to an input shaft 11a of a transmission 11; absorption dynamometers DM2, DM3 that are connected to an output shaft of the transmission 11; a shaft torque detection unit 12 that detects a value for shaft torque generated at the input shaft 11a of the transmission 11; and a control unit 13 that controls the drive dynamometer DM1. The control unit 13: uses the shaft torque value detected by the shaft torque detection unit 12 to generate a shaft torque correction value for the drive dynamometer DM1; receives an engine torque input value and uses the received engine torque input value to generate an engine torque correction value for the drive dynamometer DM1; and controls the drive dynamometer DM1 on the basis of a torque command value generated from the shaft torque correction value and the engine torque correction value.
