摘要:
This invention is intended to ensure that a control device for a vehicle drive unit is capable of realizing desired torque by making the main-actuator and sub-actuator collaborate adequately while holding the interposition of the sub-actuator as low as possible. For this end, a future target of torque that is going to be output from the engine and a realization timing of the future target are taken as reservation information for reserving engine torque regulation. Next, the required period, which is required to realize the future target when a main-actuator (a throttle) is operated to regulate the torque, is computed from a current engine operating condition. Then, the operation of the main-actuator is started at the timing preceding the realization timing by the required period for realizing the future target. In parallel with that, a sub-actuator (an ignition system) is operated to cancel out a torque change induced by the operation of the main-actuator during the period from the start timing of the operation of the main-actuator to the realization timing.
