Document Type and Number:
WIPO Patent Application WO/2018/030001
Kind Code:
A1
Abstract:
A control unit (13) of a tire mounted sensor (1) determines whether a tire 3 has been changed. When the tire (3) has been changed, the control unit (13) changes the threshold value of a road surface state determination condition used for detecting the road surface state from vibration data of the tire (3) detected by an acceleration sensor (12) of the tire mounted sensor (1). For example, the threshold value of the road surface state determination condition is reset upon determining that the tire (3) has been changed, by transmitting an instruction command to the tire mounted sensor (1) through a tool (200) at an automobile maintenance shop, etc.
