<P>PROBLEM TO BE SOLVED: To accurately stop an internal combustion engine at a predetermined target stop position by outputting proper torque from an electric motor. <P>SOLUTION: Base torque "Tbs" is set based on rotation numbers "Ne" and a crank angle "CA" (S140) after the rotation number "Ne" of an engine becomes not larger than a threshold "Nref", when the operation of the engine is stopped (YES in S130), then correction factor "k" is set, based on pressure "Pin" in a cylinder (S160). Then a value of the base torque "Tbs" multiplied by the correction factor "k" is set to a torque instruction "Tm1*" of a motor "MG1" (S170), then the engine is stopped at a predetermined target position by outputting torque from the motor "MG1". Since a proper torque instruction is thus set, in response to the pressure in the cylinder, the engine can be accurately stopped at the predetermined target stop position, as compared with what does not take into consideration the pressure inside the cylinder. <P>COPYRIGHT: (C)2009,JPO&INPIT |
