RELIABLE REMOTE PNEUMATIC PRESSURE MONITORING SYSTEM HAVING TIRE MONITORING DEVICES OPERATING IN ENERGY SAVING MODE.

摘要

The system has tire monitors (2) to sense inflation pressure of a tire and determine a change in the pressure. The monitors transmit a pressure transmitting signal only when the determined change in the pressure is greater than/equal to a preset threshold. A controller is connected with a receiver (3) and transmitters (8a-8d). The controller determines, on signal reception by the receiver, the tire pressure based on the signal. The controller controls, on signal reception, the transmitters to transmit an acknowledge signal to inform the monitors that the receiver has received the signal.
