Abstract
A motor transmission apparatus is provided between a transmission output shaft coupled to a drive wheel and a motor shaft coupled to a motor/generator. The motor transmission apparatus includes a first power transmission path that is switched to a power transmission condition by a high clutch having a clutch oil chamber, and a second power transmission path that is switched to a power transmission condition by a low brake having a brake oil chamber. Working oil discharged from an oil pump is guided to an oil passage switching valve via an output control valve. The working oil is distributed to one of the clutch oil chamber and the brake oil chamber by the oil passage switching valve, and therefore interlocking, in which the high clutch and the low brake are engaged simultaneously, can be avoided.
