Abstract
A transmitter of a tire condition monitoring apparatus has a pressure sensor, a transmitting circuit, and a transmission controller. The pressure sensor measures the air pressure of a tire. The transmitting circuit wirelessly transmits data indicating the measurement at a variable bit rate. The transmission controller controls the transmitting circuit). More specifically, the transmission controller varies the bit rate depending on the traveling speed of a vehicle, which is detected by a vehicle speed sensor. The transmission controller then causes the transmitting circuit to transmit data at the varied bit rate. Accordingly, regardless of the operation mode of the vehicle, the data is transmitted at an optimal bit rate.
Claims19
A transmitter of an apparatus for monitoring the condition of a tire attached to a vehicle, comprising:
- a tire condition sensor, wherein the tire condition sensor measures a parameter indicting the condition of the tire;
- a transmitting circuit, wherein the transmitting circuit wirelessly transmits, at a variable bit rate, data representing the measured parameter;
- and
- a controller, wherein the controller controls the variable bit rate of the data transmitted by the transmitting circuit.
An apparatus for monitoring the condition of a tire attached to a vehicle having an engine, comprising:
- a transmitter, which is attached to the tire, wherein the transmitter includes:
- a tire condition sensor, wherein the tire condition sensor measures a parameter indicting the condition of the tire;
- a transmitting circuit, wherein the transmitting circuit wirelessly transmits, at a variable bit rate, data representing measured parameter;
- and
- a controller, wherein the controller controls the variable bit rate of the data transmitted by the transmitting circuit;
- and
- a receiver, wherein the receiver receives and processes the transmitted data.
