Title:
CURRENT DETERMINATION DEVICE AND ON-VEHICLE APPARATUS
Document Type and Number:
Japanese Patent JP2017063544
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a current determination device capable of determining a current outputted from a power supply device reliably, and to provide an on-vehicle apparatus including the current determination device.SOLUTION: A current determination device includes a voltage acquisition unit for acquiring a voltage outputted from a current voltage conversion unit for converting a current outputted from a power supply device into a voltage corresponding that current, an inversion voltage acquisition unit for acquiring an inversion voltage obtained by inverting the magnitude of the voltage outputted from the current voltage conversion unit, a first conversion unit for converting the voltage, acquired in the voltage acquisition unit based on a predetermined reference voltage, into a conversion value, a second conversion unit for converting the inversion voltage, acquired in the inversion voltage acquisition unit based on a reference voltage, into a conversion value, and a determination unit for determining whether or not the current outputted from the power supply device goes above a predetermined upper limit, based on the conversion values converted in the first and second conversion units.SELECTED DRAWING: Figure 1
