<P>PROBLEM TO BE SOLVED: To provide a control device which allows miniaturization of a vehicle drive or improves fuel consumption while avoiding shock during engine air-fuel ratio control, the vehicle drive having a differential mechanism for distributing engine outputs to a first electric motor and to an output shaft and having an electric motor provided on the output shaft. <P>SOLUTION: The drive is provided which has a switching clutch C0 or a switching brake B0 so as to have the advantages of both the effect of improving the fuel consumption of a transmission where transmission ratio is electrically changed as a transmission mechanism 10 is switched between a continuously variable transmission state and a stepped transmission state, and the high transmission efficiency of a gear type transmission device for mechanically transmitting power. If transmission state switching control by a switching control means 50 and air-fuel ratio switching control by an air-fuel ratio switching control means 90 overlap, an execution control means 82 preferentially executes the transmission state switching control, and after the transmission state switching control is complete, it executes the air-fuel ratio switching control so as to avoid shock. <P>COPYRIGHT: (C)2009,JPO&INPIT |
