ABSTRACT:
An acceleration sensor state detecting apparatus for detecting a state of an acceleration sensor provided at a vibrating body includes a calculating method for calculating a difference between measured results of the acceleration sensor obtained per first predetermined time that is shorter than a vibration period of the vibrating body, and a determining method for determining that the acceleration sensor is in an error state in a case that a state in which the difference calculated falls into a range between a predetermined upper limit value and a predetermined lower limit value continues for a second predetermined time or more.
