Abstract
A vehicle drive device having a control device making another first planetary gear device constituent member and a second planetary gear device constituent member non-rotatable by a brake to perform electric motor running for running with power of a second electric motor while an engine is put into a non-drive state, when the engine is started during the electric motor running the control device causing a first electric motor to rotate the engine while the other first planetary gear device constituent member and the one second planetary gear device constituent member are kept non-rotatable by the brake, and when the brake is released after start of the engine, the control device controlling the first electric motor before release of the brake so a torque applied to the brake due to power of the engine reaches a magnitude balancing with a torque applied to the brake due to a running load.
