ABSTRACT:
A method for detecting an abnormality in a hybrid vehicle. The hybrid vehicle includes an engine that can run in a cylinder cut-off state where intake and exhaust valve lifts are made zero, and a motor/generator that functions as both a motor and a generator. The vehicle travels by means of the power of at least one of the engine and the motor/generator and carries out regenerative braking by the motor/generator while running the engine in a cylinder cut-off state during deceleration. When detecting an abnormality in a negative intake pressure sensor or an EGR control valve based on the negative intake pressure of the engine, the engine is prohibited from running in a cylinder cut-off state even during deceleration, thus generating a negative intake pressure and thereby enabling the abnormality detection to be carried out without any problems.
