Title:
ANOMALY DETECTION DEVICE FOR ON-BOARD POWER SUPPLY DEVICE, AND ON-BOARD POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/150921
Kind Code:
A1
Abstract:
Provided is a technology with which it is possible to set an allowable range corresponding to an actual operation status of an on-board power supply device, and to perform anomaly determination on the basis of the allowable range. In an on-board anomaly detection device (10), an allowable range setting unit (12B) sets an allowable range on the basis of at least one of a detected voltage, a detected current, and a detected temperature. A determination unit (12C) determines an anomaly on the basis of: an input power input to a voltage conversion unit (6) via an input-side conductive path; an output power output from the voltage conversion unit (6) via an output-side conductive path; and the allowable range set by the allowable range setting unit (12B).
