<P>PROBLEM TO BE SOLVED: To provide a tire pressure alarm apparatus capable of properly giving an alarm to a user by properly detecting a decrease in tire pressure. <P>SOLUTION: The tire pressure alarm apparatus gives the alarm to a driver of a vehicle by using an alarm device on the basis of the condition that the pressure detected by a pressure sensor for detecting the pressure of a tire provided for a vehicle wheel is lower than a threshold Pth1. The threshold Pth1 varies depending on the detected pressure obtained during a vehicle traveling motion (t3) or immediately after the vehicle traveling motion (t1, t2 and t4). <P>COPYRIGHT: (C)2013,JPO&INPIT |
