Title:
CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2020048262
Kind Code:
A
Abstract:
To appropriately detect a disconnected state of a connection between a vehicle side ground terminal and a power side ground terminal.SOLUTION: A vehicle discriminates a connection state between a vehicle side ground terminal and a power side ground terminal, on the basis of the voltage of a second connection signal line CC2 (the voltage of a detection point P2). The voltage of the second connection signal line in a disconnection state becomes higher than the voltage of the second connection signal line in a normal state, and a difference with the voltage of the second connection signal line in the normal state becomes larger as the output voltage (power voltage) U2 of an auxiliary battery becomes higher. In the vehicle, using a booster circuit, the output voltage U2 of the auxiliary battery is boosted to a voltage Ux. Then, using a voltage division resistor Rx, the power voltage Ux after boosted is divided, to cause a voltage at a point N to be a reference voltage.SELECTED DRAWING: Figure 5
