<P>PROBLEM TO BE SOLVED: To provide a controller for a drive unit for a vehicle capable of restraining a travel condition from being fluctuated, even when a mechanical shifting operation is carried out by a shift mechanism, a mode switching mechanism or the like in EV drive. <P>SOLUTION: This controller for the drive unit for the hybrid vehicle provided with an electric transmission in a power transmission route from a prime mover to wheels, and a rotation condition switching mechanism constituted mechanically in a downstream of the electric transmission in the power transmission route, and having a plurality of engagement devices for controlling a power transmission state by the rotation condition switching mechanism and engaged or released, is provided with a shift request detecting means (step S1) for detecting a switching request for the power transmission state of the rotation condition switching mechanism, and a transmission torque reducing means (step S3-S5) for reducing a transmission torque from the rotation condition switching mechanism to the electric transmission. when the switching request for the power transmission state is detected by the shift request detecting means. <P>COPYRIGHT: (C)2007,JPO&INPIT |
