Title:
WHEEL FASTENING STATE DETERMINING DEVICE
Document Type and Number:
Japanese Patent JP2016187977
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a wheel fastening state determining device which can monitor a wheel fastening state during traveling, can easily attach/detach sensors to/from a vehicle, does not influenced on vehicle weight, axle width, and supporting stiffness so much, can determine an abnormal condition reducing an influence of a disturbance, can improve determination accuracy, and can quantify a determination reference.SOLUTION: A wheel fastening state determining device is equipped with a sensor unit 3 which can be attached/detached to/from a wheel fastening portion, and an information processing device 4 such as an on-vehicle apparatus 4A and a communication terminal 4B. The information processing device 4 has a measurement timing instructing portion 23 which reads vehicle state data from a control/communication system 5 of a vehicle, and instructs measurement to the sensor unit 3 at a fixed timing; and an information processing portion 24 which determines an abnormal condition of a fastening state of the wheel fastening portion by comparing measurement data with accumulated data measured and stored under the same condition in the past.SELECTED DRAWING: Figure 7
