Abstract
The drive unit for a vehicle has an engine driving control element for driving a first motor on the basis of an engine driving signal, and driving a second motor so as to restrain a reaction force in a power distributing planetary gear due to the driving of the first motor in a state in which the stepped speed change gear connects the second motor and an output shaft by brakes. Further, the drive unit has an electrically operated oil pump for generating an operating oil pressure of the brakes, and also has a control section having an electrically operated oil pump operation control element for operating the electrically operated oil pump prior to the control of the engine driving control element on the basis of an engine starting signal outputted in a vehicle stopped state.
