Title:
TIRE STATE MONITORING SYSTEM, BATTERY DISCHARGE CAPACITY ESTIMATION PROGRAM, AND DISCHARGE CAPACITY ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/071038
Kind Code:
A1
Abstract:
The present invention comprises: a step for receiving tire state data from a tire state measurement unit (sensor unit SU); a first counting step for counting the number of times of reception; a step for receiving, together with the tire state data, data on the number of times of operations of the tire state measurement unit or on the number of cycles equivalent to standby time; a second counting step for counting the number of times of operations of the tire state measurement unit or a third counting step for counting the cycles equivalent to standby time; and a first estimation step for estimating a discharge capacity discharged by a battery that drives the tire state monitoring system on the basis of the number of times of operations counted in the first to third counting steps and the discharge capacity in each operation.
