Vehicle control device

A vehicle control device configured to control distribution of electric power supplied from power supply units to load units in a vehicle, the vehicle control device comprising:

• power supply terminal units configured to be electrically connected to the power supply units, the power supply terminal units including (i) a first power supply terminal configured to receive electric power supplied from a main power supply and (ii) a second power supply terminal configured to receive electric power supplied from an auxiliary power supply having a lower power supply capacity than the main power supply;
• load terminal units configured to be electrically connected to the load units, the load units including a priority load and a normal load, the priority load having priority over the normal load in receiving electric power, the load terminal units including (i) a priority terminal configured to be electrically connected to the priority load and (ii) a normal terminal configured to be electrically connected to the normal load;
• a first power supply line section configured to be electrically connected to the first power supply terminal;
• a second power supply line section configured to be electrically connected to the second power supply terminal included in the power supply terminal units;
• a power supply trunk section configured to be electrically connected to both of the first power supply line section and the second power supply line section;
• a trunk cutoff circuit located on the power supply trunk section, the trunk cutoff circuit configured to electrically disconnect the first power supply line section from the second power supply line section based on abnormality of at least one of a current value or a voltage value by cutting off a current flowing though the power supply trunk section;
• a priority supply line section configured to electrically connect the priority terminal to an auxiliary portion of the power supply trunk section, the auxiliary portion located between the second power supply line section and the trunk cutoff circuit;
• a normal supply line section configured to electrically connect the normal terminal to the auxiliary portion of the power supply trunk section;
• and
• a load cutoff circuit configured to electrically disconnect, via the normal supply line section, the normal terminal from the power supply trunk section based on abnormality of the voltage value or the current value caused by a decrease in power supply of the priority supply line section in a state where the trunk cutoff circuit cuts off the current flowing through the power supply trunk section.
