Abstract:
A vehicle including an internal combustion engine provided with a plurality of cylinders, and a control unit that determines that an abnormality of the internal combustion engine has occurred when an atmospheric pressure has a first value and an operation state represented by at least one of an output shaft revolution speed and a load of the internal combustion engine is within a preset region and determines that an abnormality of the internal combustion engine has occurred when the atmospheric pressure has a second value that is lower than the first value and the operation state is outside the region.
