<P>PROBLEM TO BE SOLVED: To provide a control device for a vehicle drive mechanism, enabling to sufficiently improve the power performance of a vehicle by increasing a torque ratio and changing a capacity coefficient to be lower, while avoiding the stop of an internal combustion engine even in the state of setting the fuel-cut reset revolving speed of the internal combustion engine to be lower. <P>SOLUTION: A capacity coefficient control means 122 lowers a capacity coefficient C of a torque converter 6 during fuel-cut of the engine 9 when reducing the speed of the vehicle, to secure a rotating speed difference between a pump impeller 6p and a turbine impeller 6t, namely, a rotating speed difference between the engine 9 and the turbine impeller 6t even when the vehicle is suddenly stopped, e.g., therefore preventing the stop of the engine 9. Thus, the fuel-cut reset revolving speed Ncut can be set to be further lower than conventional one, resulting in improved fuel consumption. <P>COPYRIGHT: (C)2010,JPO&INPIT |
