Abstract:
1. An apparatus for monitoring the condition of a tire of a vehicle, the apparatus comprising: a commander having an operation switch, wherein the commander transmits an instruction signal when the operation switch is turned on; a transmitter provided in the tire, wherein a unique identification data is assigned to the transmitter in advance, and wherein the transmitter includes a tire condition sensor for detecting the condition of the tire, a receiving portion for receiving the instruction signal, and a transmitting portion for transmitting signals; and a receiver located in the body of the vehicle, wherein the receiver includes a receiving portion for receiving signals transmitted from the transmitter and a rewritable ID memory for storing the identification data of the transmitter, wherein the transmitter has a first transmission mode, in which the transmitter transmits a signal regardless whether the commander transmits the instruction signal, and a second transmission mode, in which the transmitter transmits a signal in response to the instruction signal from the commander, wherein the signal transmitted according to the first transmission mode is a first signal, the first signal including at least data representing the tire condition detected by the tire condition sensor and the identification data, and wherein the signal transmitted according to the second transmission mode is a second signal, the second signal including at least the identification data, and wherein, when receiving the first signal, the receiver continues processing the received first signal if the identification data in the received first signal matches with the identification data in the ID memory, and wherein, when receiving the second signal, the receiver stores the identification data in the received second signal in the ID memory.
