Abstract
A hybrid-vehicle driving system includes an engine, a transmission, a first motor/generator provided between the engine and the transmission, and a battery that can charge and discharge the first motor/generator. When an estimated output voltage of the first motor/generator becomes higher than or equal to a predetermined voltage during a gear shift operation of the transmission, the battery is electrically disconnected from the driving system, and the voltage of a power line on the side of the first motor/generator is then decreased so as to charge the battery.
