Abstract:
A hybrid vehicle includes: a multi-cylinder internal combustion engine and an electric motor, a power source control unit that controls the engine and the motor, an air-fuel ratio control unit that controls the air-fuel ratio of exhaust gas of the engine to obtain a target air-fuel ratio, a battery that stores electric power that is supplied to the motor, a state-of-charge detection unit that detects a state-of-charge of the battery, a detection unit that detects an air-fuel ratio imbalance abnormality of the internal combustion engine and identifies an abnormal cylinder that has caused the imbalance abnormality, and a correction unit that corrects, in a case where the air-fuel ratio imbalance abnormality has been detected, a fuel injection amount of the abnormal cylinder based on a battery state-of-charge decrease amount from when the abnormality is detected to the time when a predetermined time interval is elapsed after the detection.
