Title:
DETECTOR AND TIRE AIR PRESSURE MONITORING SYSTEM
Document Type and Number:
Japanese Patent JP2018187981
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a detector that is provided in a tire, the power consumption of which can be suppressed, and which can detect tire air pressure early in required timing.SOLUTION: When receiving a request signal, a detector detects air pressure of a tire provided in a vehicle, and transmits an air pressure signal including air pressure information obtained by detection. The detector comprises a reception part that receives the request signal in a first state by operating in such a manner as to periodically switch between the first state in which the request signal can be received and a second state in which power consumption is lower than in the first state and in which the request signal is not received, and a control part that changes frequency of a shift to the first state.SELECTED DRAWING: Figure 1
