Title:
タイヤ情報管理システム
Document Type and Number:
Japanese Patent JP5019839
Kind Code:
B2
Abstract:
In a tire information management system 10 of the present invention, a vehicle side module 5 includes a receiving electromagnetic wave strength measuring means 12 for measuring, for each sensor module 3, receiving electromagnetic wave strength of data signals transmitted from the sensor module 3 and is adapted to generate a transmitting electromagnetic wave strength set value to be employed in the next data transmission by the sensor module in accordance with the receiving electromagnetic wave strength of the data signals transmitted from the sensor module and add the transmitting electromagnetic wave strength set value to a command to the sensor module at the next request of data transmission thereto. The sensor module 3 includes a transmitting electromagnetic wave strength control means 16 for controlling transmitting electromagnetic wave strength in data transmission. The transmitting electromagnetic wave strength control means 16 is adapted to control transmitting electromagnetic wave strength during next data transmission on the basis of a transmitting electromagnetic wave strength set value received from the vehicle side module. As a result, the present invention provides a tire information management system that allows electricity consumption at the sensor module to be significantly reduced, whereby the product life of the sensor module is significantly improved.
