Patent ID: 8209104

Claim:
A control device for a vehicle drive unit having an internal combustion engine as a power plant, the control device comprising: vehicle control means which performs control concerning the drive condition of a vehicle by regulating a torque output by the internal combustion engine; a main-actuator used for regulating the torque of the internal combustion engine; a sub-actuator which makes the torque respond to its operation more promptly than the main-actuator does, and is used for torque regulation of the internal combustion engine independently of the main-actuator; reservation information taking means which receives a reservation of torque regulation supplied from the vehicle control means to the internal combustion engine, and takes as reservation information at least a future target of the torque that is going to be output from the internal combustion engine and a realization timing of the future target; required period computing means which computes based on a current engine operating condition the period required to realize the future target under a situation in which the torque of the internal combustion engine is regulated by operating the main-actuator; wherein, in a first operating mode, a main-actuator control means starts the operation of the main-actuator at the timing preceding the realization timing by the required period for realizing the future target; and a sub-actuator control means operates the sub-actuator to cancel the torque change induced by the operation of the main-actuator during the period from the start of the operation of the main-actuator to the realization timing.
