Abstract
A vehicle includes an engine, first and second motor generators, a power split device, a propeller shaft, an automatic transmission, and an ECU. The power split device includes a carrier, a sun gear, and a ring gear respectively coupled to a crankshaft of the engine, a rotor of the first motor generator, and a rotation shaft of the second motor generator. The automatic transmission is provided between the second motor generator and a propeller shaft. When the first motor generator has a malfunction, the ECU restricts gear shift performed by the automatic transmission, as compared with a case where the second motor generator has a malfunction.
