Title:
SENSOR TRANSMITTER, WHEEL POSITION DETECTION DEVICE, AND TIRE AIR PRESSURE DETECTION DEVICE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2018/131664
Kind Code:
A1
Abstract:
Each sensor transmitter (2) itself calculates the inclination angle (θset) of a G sensor (22) mounted to a wheel (any of 5a to 5d), and estimates which of the right wheels (5a, 5c) and the left wheels (5b, 5d) the sensor transmitter is mounted to on the basis of calculated quadratic and linear functions and measured quadratic and linear functions. Then, for each sensor transmitter (2), it is identified on a receiver (3) side, on the basis of the estimation result and an effective tire radius, which of the front wheel (5a, 5b) or the rear wheel (5c, 5d) the sensor transmitter (2) is mounted to. Accordingly, it can be identified which of the wheels (5a to 5d) the respective sensor transmitters (2) are mounted to.
