<P>PROBLEM TO BE SOLVED: To achieve engine stop in that the negative torque of the motor when the ignition switch is turned off in a first clutch engagement state in selecting a non-travel range, does not deteriorate sound vibration performance of the vehicle. <P>SOLUTION: When stopping the engine at high revolution that exceeding the idling speed Neid after the warm up (S17) by ignition switch OFF (S11) when selecting non-travel range (S15) and leaving a first clutch locked state (S13), the engine is stopped after the engine speed Ne is decreased to the idling speed Neid by S19. On this occasion, the motor is controlled by setting the target motor torque tTm so that the target rotation number of the motor tNm is decreased by the prescribed change rate ΔNm and the motor rotation speed Nm may follow to this target tNm. As a result, the variation of the target motor torque tTm when the engine rotation is decreased, is controlled to the extent that may not enlarge the target motor torque tTm more than the value in the sound vibration allowance range. <P>COPYRIGHT: (C)2012,JPO&INPIT |
