Title:
FAILURE PREDICTION SYSTEM, FAILURE PREDICTION METHOD, AND FAILURE PREDICTION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/176622
Kind Code:
A1
Abstract:
An acquisition unit (111) acquires travel data of an electric vehicle. A prediction unit (112) predicts a failure due to aging in a drive circuit of a motor for driving a drive wheel of the electric vehicle on the basis of the travel data of the electric vehicle. The travel data includes position data and power-consumption-related data of the electric vehicle. The prediction unit (112) predicts a failure due to aging in the drive circuit on the basis of the increased trend of a power consumption amount obtained each time the electric vehicle travels the same route.
