Electric power distribution system
An electric power distribution system includes a first path through which electric power is supplied from a DC/DC converter to a driven load to be driven in a load group; a second path connected in parallel with the first path and through which electric power is supplied from the battery to the driven load; a third path connected in series with the second path and connecting the DC/DC converter and the battery; a first switching circuit provided in the third path and switched to either ON state or OFF state; and a control unit switching the first switching circuit to either the ON state or the OFF state based on travel route information of a navigation system. The control unit switches the first switching circuit to the ON state according to a peak current of a load current of the driven load derived from the travel route information.
1. An electric power distribution system which is mounted in a vehicle and supplies electric power from at least one of a DC/DC converter and a battery, the electric power distribution system comprising:
a first path through which electric power is supplied from the DC/DC converter to a driven load to be driven in a load group;
a second path that is connected in parallel with the first path and through which electric power is supplied from the battery to the driven load;
a third path that is connected in series with the second path and connects the DC/DC converter and the battery;
a first switching circuit that is provided in the third path and is able to be switched to any one of an ON state and an OFF state; and
a control unit that switches the first switching circuit to any one of the ON state and the OFF state based on travel route information of a navigation system mounted on the vehicle,
wherein the control unit switches the first switching circuit to the ON state according to a peak current of a load current of the driven load derived based on the travel route information.
2. The electric power distribution system according to claim 1 , wherein
the peak current is generated in a time zone in which an output current of the DC/DC converter exceeds a rated current of the DC/DC converter, and
the control unit maintains the ON state of the first switching circuit in the time zone.
3. The electric power distribution system according to claim 1 , wherein
the control unit derives the peak current for each travel area analyzed based on the travel route information, and
each of the travel areas is predicted to be passed by vehicle during traveling and is one of a rectilinear area and an intersection area.
