<P>PROBLEM TO BE SOLVED: To optimize a relationship between the vibration damping control of an internal combustion engine using a rotating electric machine which is drive-connected to the internal combustion engine and the pulsation suppression control of torque by the setting of the operation state of the internal combustion engine. <P>SOLUTION: This control device of a drive unit comprises: a pulsation torque calculation part 5 which calculates pulsation torque to be damped in vibration being pulsation torque to be an object to be damped in vibration on the basis of the present operation state of the internal combustion engine 11 and the present pulsation torque; an output-possible vibration damping torque calculation part 6 which calculates output-possible vibration damping torque being the maximum value of the vibration damping torque which can be outputted by the rotating electric machine 12 in the present operation state of the rotating electric machine 12 on the basis of the present operation state of the rotating electric machine 12 and a vibration damping controllable range which is set in advance with respect to the operation state of the rotating electric machine 12; and an internal combustion engine control part 3 which changes the operation state of the internal combustion engine 11 in a direction in which the output torque of the internal combustion engine 11 is lowered while maintaining power of the internal combustion engine 11 when the pulsation torque to be damped in vibration is larger than the output-possible vibration damping torque. <P>COPYRIGHT: (C)2013,JPO&INPIT |
