Title:
ON-VEHICLE POWER SOURCE SWITCH APPARATUS AND CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/169817
Kind Code:
A1
Abstract:
Provided is an on-vehicle power source switch apparatus capable of surely turning off a switch provided between two power storage devices when grounding occurs. A first system includes: a generator; a first power storage device charged by the generator; and a first vehicle load to which power is supplied from the first power storage device. A second system includes: a second power storage device; and a second vehicle load to which power is supplied from the second power storage device. A separation switch is connected between the first system and the second system. A first control circuit and a second control circuit respectively output a first virtual control signal and a second virtual control signal for controlling the separation switch. A logical circuit turns on the separation switch when the first virtual control signal and the second virtual control signal both indicate on. The first control circuit and the second control circuit output a first virtual control signal and a second virtual control signal that indicate on, during the power generation by the generator, and output a first virtual control signal and a second virtual control signal that indicate off, when grounding occurs.
