Document Type and Number:
Japanese Patent JP2014128982
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a tire position determination system capable of securing the accuracy in determining a tire position.SOLUTION: A pulse combination determination part 24 performs: checking, for a data string representing a pulse output sequence of axle rotation speed detection sensors 19a-19d, as to whether the data string contains pulses of all of the axle rotation speed detection sensors 19a-19d; and moving up a date string by discarding one piece of a head data string when a new pulse is output, if the data string does not contain pulses of the axle rotation speed detection sensors 19a-19d, and to check a combination of pulses as performed before and repeat the aforementioned checking until all pulses appear. Timing of pulses of all the axle rotation speed detection sensors 19a-19d appearing in a data string is set as a pulse import timing.
