Title:
DEVICE FOR DETERMINING WHEEL FASTENING STATE USING SERVER
Document Type and Number:
WIPO Patent Application WO/2016/186030
Kind Code:
A1
Abstract:
Provided is a device for determining a wheel fastening state, whereby a wheel fastening state can be monitored during travel, an abnormality can be determined with reduced effects of external disturbances by specifying a vehicle travel condition during measurement, the precision of determination can be enhanced and a reference for determination can be quantified, further enhanced precision of determination is possible through increased capacity for information accumulation, and the speed of state determination is increased. The present invention is provided with a sensor unit (3) which can be attached to and detached from a wheel fastening part, an information terminal (4) which is a vehicle-mounted device (4A) or a portable terminal (4B), and a server (30). The information terminal (4) has a measurement instruction part (23) for reading vehicle state data from a control/communication system (5) of a vehicle and instructing the sensor unit (3) to perform measurement at a prescribed timing. The server (30) has a first information processing part (32) for comparing measurement data with accumulated data measured in the past under the same conditions and stored, and thereby determining an abnormality in the fastening state of the wheel fastening part.
