Abstract: A hybrid vehicle includes an engine, a motor, and a controller. The controller is configured to control the engine and the motor. The controller is configured to, when the engine is operated under load at the time when the vehicle slows down and stops in an autonomous driving mode in which the vehicle runs without driver's operation, set a controlling lower limit rotation speed of the engine to a maximum rotation speed out of a plurality of candidate rotation speeds and control the engine such that the engine is operated under load within a range higher than or equal to the controlling lower limit rotation speed.

Abstract: A driving device includes a motor; a power storage device; a first boost converter configured to exchange power by voltage conversion between a power storage device side and a motor side; a second boost converter connected to the first boost converter in parallel and configured to exchange power by voltage conversion between the power storage device side and the motor side; and an electronic control unit configured to control the first boost converter and the second boost converter. The electronic control unit controls the first boost converter and the second boost converter such that the loss of each of the first boost converter and the second boost converter is not minimized during an excessive power input in which power to be input to the power storage device from the motor side is greater than an input limit of the power storage device.
