Title:
TIRE PNEUMATIC PRESSURE MONITORING DEVICE FOR VEHICLE AND MONITOR DEVICE IN THE SAME
Document Type and Number:
Japanese Patent JP3892271
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a tire pneumatic pressure monitoring device for a vehicle capable of easily and securely detecting an abnormal condition and an abnormal section of a tire for the vehicle.
SOLUTION: A microcomputer 17 switches a possibility and an impossibility for receiving a radio signal of reception antennas 13a to 13d when the reception antennas 13a to 13d receive the radio signal to monitor reception intensity of each reception antenna 13a to 13d. The microcomputer 17 specifies sensor devices 11a to 11d transmitting radio signals based on the reception intensity. Moreover, it judges an abnormality of tires 3a to 3d corresponding to the specified sensor devices 11a to 11d based on tire information included in the received radio signal. As a result, the microcomputer 17 displays that the tire information in the radio signal indicates an abnormal condition in a display device 15 if the tire information indicates the abnormal condition and displays in which tire of 3a to 3d an abnormality occurs.
