ID registration method of tire pressure sensor, and a tire pressure monitoring system and tire pressure sensor, tire pressure monitoring program

摘要

PROBLEM TO BE SOLVED: To prevent entry into registration mode erroneously during usual running while preventing erroneous registration caused by interference when registering ID in a tire pneumatic pressure monitoring device.;SOLUTION: When sensor ID in a received signal does not agree with already registered ID (S120:NO), it is determined whether pneumatic pressure detection data in the signal is below the atmospheric pressure or not (S150). If the data is below the atmospheric pressure, it is determined whether the number of ID temporary registration is 0 or not (S160). If the number of ID temporary registration is 0, a registration timer T is reset (S170). Next, it is determined whether the registration timer T is less than 60 seconds or not (S180). If the timer is less than 60 seconds, ID is temporarily registered (S190). It is determined whether the number of ID temporary registration becomes 4 or not (S200). If it is determined that the number of temporary registration is 4, sensor ID is actually registered (S210). If the registration timer T is above 60 seconds, the temporarily registered ID is cleared (S220).;COPYRIGHT: (C)2004,JPO
