Abstract
A vehicle includes an engine, a second MG for running, a battery that supplies and receives electric power to and from the second MG, and an ECU. The ECU is configured to control the engine and the second MG and to execute intake air amount learning. When the SOC of the battery exceeds a second threshold value that is higher than a first threshold value while the vehicle is running using the second MG with the engine in a stopped state, the ECU maintains the engine in the stopped state and maintains the second MG in a driven state, and then does not execute the intake air amount learning. When the SOC of the battery takes a value between the first threshold value and the second threshold value, the ECU starts the engine, drives the second MG with constant torque, and executes the intake air amount learning.
