Abstract
The present invention offers a pressure monitor and a method of controlling the pressure monitor for a vehicle tire which enable reducing electric power consumption and issuing an alarm, when the tire pressure is equal to or lower than a predetermined alarm tire pressure. The pressure monitor comprises a signal sending device and a signal receiving device. The signal sending device includes a tire pressure sensor and a battery. The tire pressure sensor detects a tire pressure at each interval time, a predetermined unit time .delta.t. The signal sending device sends an electric signal to the signal receiving device. The signal receiving device receives the electric signal from the signal sending device and issues an alarm when the detected tire pressure is equal to or lower than a predetermined tire pressure P1, P2 and P3 (P1>P2>P3). The signal sending device is installed on a wheel and is driven by the battery. The signal sending device sends the electric signal of the tire pressure detected by the tire pressure sensor at periodical interval .DELTA.T and sends at the time when a change in the value of the detected tire pressure in the interval n2.times..delta.t is equal to or more than the value of n2.times..delta.pt. The number n2 is set to satisfy with 0
