Title:
車輪位置検出装置およびそれを備えたタイヤ空気圧検出装置
Document Type and Number:
Japanese Patent JP5477368
Kind Code:
B2
Abstract:
A wheel position detector for a vehicle includes: a transmitter at each wheel having a first controller for generating and repeatedly transmitting a frame with specific identification information and an acceleration sensor; a receiver at a vehicle body receiving the frame from one wheel and having a second controller for performing wheel position detection; and a wheel speed sensor for detecting a tooth of a gear. The second controller acquires gear information indicating a tooth position; sets a variation allowance based on the tooth position; registers the one wheel with using the variation allowance; sets another variation allowance based on another tooth position when the receiver receives a new frame; and changes the variation allowance to a new variation allowance provided by an overlap portion between the variation allowance and another variation allowance.
