TIRE INFLATION PRESSURE WARNING SYSTEM

摘要

PROBLEM TO BE SOLVED: To enhance response by establishing transmission conditions for a transmitter in accordance with the degree of a reduction in tire inflation pressure. SOLUTION: A transmitter 4 for transmitting information on tire air pressure for every given time is mounted on a tire and a receiver 7 is provided on a car body side to receive the tire inflation pressure information to identify the information for display. In that tire inflation pressure warming system, a transmitting signal is transmitted for every given time and is also transmitted when a fluctuation in the rapid pressure of the tire at a unit time t exceeds given pressure (P1).
