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.

Hybrid vehicle

A control device for a vehicular automatic transmission is provided which can preferably execute backpressure control of accumulators and torque-up control so as to minimize the occurrence of interference between learning on these controls during a gearshift operation. With the control device for the vehicular automatic transmission including the accumulators (and) operative to control a hydraulic pressure supplied to second and third clutches (Cand C) and a third brake (B), the backpressure control is executed for controlling a backpressure of the accumulators (and) during the gearshift operation while the torque-up control is executed for raising torque output from an engine (). Completion of learning on the backpressure control is determined when no completion of learning on the backpressure control is determined, learning on the backpressure control is executed with no execution of the torque-up control. Thus, no interference occur between learning on the backpressure control and the torque-up control.
