  "textContent": "A vehicle comprises: an internal combustion engine (7) which can be motorized by a generator (6); an exhaust catalyst device (24) which purifies the exhaust gas of the internal combustion engine (7); and an A/F sensor (47) which is located on the upstream side of the exhaust catalyst device (24) and detects an air-fuel ratio. When the oxygen storage amount of the exhaust catalyst device (24) increases but the effect on the exhaust performance on the downstream side of the exhaust catalyst device (24) is small, the fuel injection of the internal combustion engine (7) is stopped. The internal combustion engine (7) is motorized, and air-fuel ratio learning for learning the detection value of the A/F sensor (47) is performed. This makes it possible to motorize the internal combustion engine (7) without causing deterioration in exhaust performance. Further, the air-fuel ratio learning can be performed without causing deterioration in exhaust performance.",
