Tire sensor device and tire information transmission method
First Claim
1. A tire sensor device comprising:
- plurality of sensor devices installed at predetermined locations of a tire; and
a base station arranged in a tire interior and which communicates with the plurality of sensor devices;
whereineach of the sensor devices has a sensor which detect a condition of the tire and a communication device,the base station comprises;
an internal communication device having a first antenna and communicating with the plurality of sensor devices;
an information processing device which processes a tire information signal wherein the tire information signal is information of condition of the tire detected in the sensor; and
an external communication device having a second antenna and transmitting processed tire information to a car body side, wherein;
the first antenna is arranged on a tire air chamber side of a wheel,the second antenna is arranged on an opposite side to the tire air chamber side of the wheel, andthe communication device of the sensor devices has an antenna arranged on the tire air chamber side and is operable to communicate with only the base station and other sensor devices.

Abstract
A tire sensor device comprising sensor modules 20A to 20D, each comprising a sensor, a communication module having a communication function and a power regenerating circuit, and an antenna; and a base station comprising an internal communication device for communication with the sensor modules 20A to 20D, an information processing device for processing tire information signals from the sensor modules, an external communication device for communicating with a car control device 40 on the car body side and a power source. The sensor modules 20A to 20D and the base station 30 are arranged in the tire and constitute an intra-tire LAN. Tire information signals transmitted from the sensor modules 20A to 20D are processed by the base station 30 and transmitted to the car control device 40 so that appropriate tire information can be obtained and the size and power consumption of the sensor device can be reduced.
