PROBLEM TO BE SOLVED: To provide an operation method for an on-vehicle electric motor, preventing the impression of ball bearings by giving somewhat rotational drive to the electric motor during the travel of an automobile. SOLUTION: In the operation method for the electric motor 7, an auxiliary oil pump 8 is driven for supplying ATF hydraulic pressure to a transmission 3 via rotating shaft 9 journaled by the ball bearings 10, 11 only during the idle stop of an engine 1. When the automobile is travelling and the auxiliary oil pump 8 is not used, creeping speed rotation or intermittent rotation is given to the electric motor 7. COPYRIGHT: (C)2005,JPO&NCIPI |
