Abstract:
A method and an apparatus configured to acquire, as acceleration information, a peak level a k  which is a magnitude of a peak on a positive side or a negative side of an acceleration signal in a tire circumferential direction or a tire width direction detected by an acceleration sensor, or a peak interval b k  which is a time interval between peaks, or acquire the peak level a k  or the peak interval b k  of a differential acceleration signal in a tire radial direction obtained by differentiating the acceleration signal in the tire radial direction; calculate ratios P k , Q k  of a difference between the acquired acceleration information a k , b k  and average values A k−1  of the acceleration information to the average values; and determine that the acceleration sensor is detached from the inside of the tire when the calculated ratio P k , Q k  exceeds a preset threshold value K p , K q  by multiple times successively.

Claim (Index 6):
An apparatus for determining detachment of an acceleration sensor attached to inside of a tire for detecting an acceleration signal in a tire radial direction, the apparatus comprising:\n a differential acceleration calculation means for differentiating the acceleration signal to calculate a differential acceleration in the tire radial direction;\n an acceleration information acquisition means for acquiring, as acceleration information, one or both of a peak level and a peak interval of the differential acceleration signal; \n an average value calculation means for calculating an average value of the acquired acceleration information, \n a difference ratio calculation means for calculating a difference ratio which is a ratio of a difference between the acquired acceleration information and the calculated average value to the calculated average value; and \n a detachment determination means for determining whether or not the acceleration sensor is detached from the inside of the tire based on the difference ratio, \n wherein the average value calculation means calculates the average value of the acceleration information of at least three of acceleration information immediately before the acquired acceleration information, and \n the detachment determination means determines that the acceleration sensor is detached from the inside of the tire when the difference ratio exceeds a threshold value by a plurality of number of times successively.
