ABSTRACT:
A tire pressure monitoring system having a monitoring unit that receives the output of a transmitted pressure sensor through a receiving antenna, and compares the output with a predetermined value to determine whether the tire pressure is proper, and informs a result of the determination to an operator by an indicator or alarm section connected to an onboard battery through an ignition switch. In the system, an operating switch is installed in a vehicle compartment to be operable by the operator for supplying the operating power to the indicator by connecting it to the battery, while bypassing the ignition switch. Alternatively, a portable terminal device to be carried by the operator is connected to the monitoring unit in such a manner that the monitoring unit transmits the result of the determination to the portable terminal device to inform the result of the determination to the operator by a second indicator provided at the portable terminal device. With this, the operator's work is facilitated when pumping up the tire with insufficient pressure.
