<P>PROBLEM TO BE SOLVED: To enable detection of a start point where a second clutch is slip-engaged between a power source and a drive wheel. <P>SOLUTION: An engine as the power source and a motor/generator are coupled via a first clutch, and this power source and drive wheel are connected via the second clutch inside an automatic transmission. In an idle driving mode in which the engine is operated, when the automatic transmission is switched from an N range to a D range, the second clutch is shifted from a released state to slip engagement, and the start point S of this slip engagement is detected from a change of a torque of the motor/generator. When the automatic transmission is switched to the D range, a change of a target engine torque and a target number of revolutions of the motor/generator is restricted, and the fixed target engine torque and the fixed target number of revolutions are maintained. The start point S of the slip engagement is detected with high accuracy without being disturbed by the fixed target engine torque and the fixed target number of revolutions. <P>COPYRIGHT: (C)2012,JPO&INPIT |
