A drive system for a hybrid vehicle includes a planetary gear unit, a first rotating machine connected to a sun gear of the planetary gear unit, an engine connected to a carrier of the planetary gear unit, a second rotating machine and drive wheels connected to a ring gear of the planetary gear unit, a regulating mechanism that regulates rotation of the carrier, a first running mode in which the vehicle runs using the second rotating machine as a power source, and a second running mode in which the vehicle runs using the first rotating machine and the second rotating machine as power sources while the regulating mechanism regulates rotation of the carrier. The carrier is rotated by the first rotating machine (S40) when the vehicle shifts from the first running mode to the second running mode (S30-Y). |
