<p>The objective is to improve regeneration efficiency by reducing the amount of time until a direct clutch completely engages, while suppressing the occurrence of shock caused by the engagement of the direct clutch. Disclosed is a control device that is equipped with a transmission device and with a fluid coupling having a direct clutch, and that controls a vehicle drive device which outputs to an output member the rotation of an input member which is drive-coupled to an engine and a rotating electric machine, said control device being further equipped with: a rotation difference acquisition means which acquires the difference (?N) in the rotational velocity, which is the difference between the rotational velocities of the input side and the output side of the fluid coupling; a direct connection control means which reduces the difference in the rotational velocities and changes the state of the direct clutch from the released state to the engaged state by increasing the engagement pressure of the direct clutch with a normal pressure increase rate that is determined according to the vehicle's driving state; and a pressure-increase control means which changes the engagement pressure by the direct connection control means to a high-speed pressure increase rate which is greater than the normal pressure increase rate when the difference (?N) in the rotational velocity is at or below a permissible pressure increase threshold value (C2) while the degree of accelerator opening of the vehicle is in the reduced state.</p> |
