Abstract

A sensor failure prediction system is a sensor failure prediction system that predicts a failure of a physical quantity sensor including a vibrator element which is driven and vibrates by a drive signal and outputs a detection signal based on a physical quantity, and includes a memory that stores reference information on a reference value of the drive signal or the detection signal, and a processor that outputs prediction information on a stepwise or continuous state until the physical quantity sensor fails, based on signal information on a measurement value of the drive signal or the detection signal and the reference information.
