Abstract
A driving system, vehicle, and control method in which a difference between the detection value of an intake air pressure sensor and an atmospheric pressure sensor is computed as a detection value difference in the engine stop condition. An estimate of a potential for an abnormality of the detection value difference is determined, or the abnormality of the detection value difference is determined according to the duration time of an unusual state having the detection value difference of greater than a preset reference value. In an ignition-on state, when a delayed activation is requested, it is identified whether the abnormality in the detection value difference is to be determined. The delayed activation is requested in response to confirmation of a potential abnormality condition where there is a potential for an abnormality in the detection value difference but the abnormality in the detection value difference is not determined.
