<P>PROBLEM TO BE SOLVED: To determine the occurrence of idling even in a region in which determination based on a load of an electric oil pump becomes difficult. <P>SOLUTION: A determination target rotating speed tNset higher than a required rotating speed tNreq according to an operation request of the electrid oil pump is set, and control of an electric motor is executed to make the rotating speed N of the electric oil pump reach the determination target rotating speed tNset. A load (phase current Ii) of the electrid oil pump during execution of the control of the electric motor is detected, and the occurrence of idling in the electric oil pump is determined based on the detected pump load (Inrm, Iidl). <P>COPYRIGHT: (C)2013,JPO&INPIT |
