<p><P>PROBLEM TO BE SOLVED: To provide a testing method and a device capable of steadily and repeatedly carrying out a test by simple structure in view of a problem wherein a constitution of duplexing a motor for generating hydraulic pressure for clutch control and directly coupling rotating shafts of the two motors excels in improving reliability but has a fault of failing to detect easily when one of the motors malfunctions. <P>SOLUTION: The device has a region of "play" where a clutch is not operated in a low region of hydraulic pressure even if hydraulic pressure is supplied to a clutch control cylinder in the connected state of the clutch. In a testing procedure, operation can be individually confirmed on each motor by performing motor position control on each of the duplexed motors in the region of play. This testing procedure can be carried out by automatically starting the device during the warming-up of an engine or starting it by operation. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
