Abstract
A vehicle includes an engine, a first motor generator, a second motor generator, a transmission, a differential device, and an electronic control unit. The transmission includes an input shaft, an output shaft, and a clutch. The electronic control unit is configured to detect a rotation speed difference between the input shaft and the output shaft when the clutch is controlled so as to be brought into a power transmission shut-off state. The electronic control unit is configured to, when the rotation speed difference detected by the electronic control unit is smaller than a target rotation speed difference between the input shaft and the output shaft that occurs in a case where the power transmission shut-off state of the clutch is established, suppress cranking of the engine by the first motor generator.
