Title:
タイヤ情報通信システム
Document Type and Number:
Japanese Patent JP4856423
Kind Code:
B2
Abstract:
A tire information communication system mounted on a vehicle (11) includes a tire-pressure detector (30) mounted on a tire wheel (14) for detecting a pressure of a tire and transmitting a result of detection, a tire monitor (50) mounted on a vehicle body (12) for obtaining information about tire pressure from the tire-pressure detector (30), a tire-side transmission circuit (39) provided in the tire-pressure detector (30) for applying AC voltage containing information about tire pressure between the tire wheel (14) and an annular conductor (15B, 15C) of the tire (15) so that a radio wave is radiated from the annular conductor (15B, 15C), a vehicle ground isolation (20, 81-84, 94, 95) provided in the tire monitor (50) so as to receive the radio wave from the annular conductor (15B, 15C) thereby to be capable of generating AC voltage between the vehicle ground (19) and itself, and a body-side receiving circuit (52) provided in the tire monitor (50) and connected to the vehicle ground (19) and vehicle ground isolation (20) respectively for obtaining the information about the tire pressure from the AC voltage generated between the vehicle ground (19) and the vehicle ground isolation (20, 81-84, 94, 95).
