<p>PROBLEM TO BE SOLVED: To improve the fuel consumption by providing a clutch control means for controlling a clutch mechanism on the basis of the residual value of power fluctuation of an engine canceled by a rotating machine and setting the relative rotating speeds of rotating members corresponding to the transmitted power. SOLUTION: The residual fluctuation after the fluctuation of engine torque is cancelled by a motor generator 3 is estimated, and the engagement pressure of a lockup clutch 11 is controlled on the basis of the estimation result to control the relative rotating speeds of a pump impeller 7 and a turbine runner 9 corresponding to the transmitted power. Accordingly, the relative rotating speeds of the pump impeller 7 and the turbine runner 9 corresponding to the transmitted power, or the power transmission efficiency can be controlled according to the canceling function of engine torque fluctuation by the motor generator 3, and the fuel consumption can be improved.</p> |
