<P>PROBLEM TO BE SOLVED: To provide a control device for a vehicle drive unit, which can estimate friction torque without using a clutch friction coefficient or the like affected by a vehicle state. <P>SOLUTION: The control device for the vehicle drive unit includes: a rotation speed acquisition part which acquires the rotation speed of an internal combustion engine; a friction torque operation part which calculates a rotation change rate on the basis of a change of the rotation speed of the internal combustion engine in a combustion stop state of the internal combustion engine, and operates the friction torque of the internal combustion engine on the basis of the inertia of the combustion engine and the rotation change rate; and a management part which learns a relationship between the rotation speed acquired by the rotation speed acquisition part and the friction torque which is operated by the friction torque operation part on the basis of the rotation speed when stopping the internal combustion engine, and constructs a friction torque lead-out part which leads out the friction torque from the rotation speed on the basis of the result of the learning. <P>COPYRIGHT: (C)2012,JPO&INPIT |
