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