Abstract

A power distribution apparatus of a vehicle includes a power input terminal configured to receive power. A power output terminal is connected to a load and a main fuse is connected to the power input terminal and to the load through the power output terminal. A number of sub fuses are connected to the power input terminal and a switching circuit is provided between the plurality of sub fuses and the power output terminal. A controller is configured to supply power to the load through the main fuse in response to an operation signal of the load and control the switching circuit so that at least one of the plurality of sub fuses is selectively connected to the load.

First claim

What is claimed is:

1. A power distribution apparatus of a vehicle, the apparatus comprising:
a power input terminal configured to receive power;
a power output terminal to be connected to a load;
a main fuse connected to the power input terminal and connected to the power output terminal;
a plurality of sub fuses connected to the power input terminal;
a switching circuit provided between the plurality of sub fuses and the power output terminal; and
a controller configured to supply power to the load through the main fuse in response to an operation signal of the load and to control the switching circuit so that at least one of the plurality of sub fuses is selectively connected to the load, wherein the controller is configured to select the at least one of the plurality of sub fuses to be connected to the load based on a remaining usage count of the main fuse and a remaining usage count of each of the plurality of sub fuses.

2. The apparatus according to claim 1 , wherein the controller is configured to calculate the remaining usage count of the main fuse and the remaining usage count of each of the plurality of sub fuses based on usage history data of the main fuse, durability data of the main fuse, usage history data of each of the plurality of sub fuses, and durability data of each of the plurality of sub fuses.

3. The apparatus according to claim 1 , wherein the controller is configured to calculate the remaining usage count for each fuse in each set of a plurality of sets, each set including the main fuse and at least one of the plurality of sub fuses, and select the at least one of the plurality of sub fuses based on the set among the plurality of sets having the sum of calculated remaining usage count of each fuse that is the maximum.

4. The apparatus according to claim 1 , wherein the controller is configured to determine whether the remaining usage count of the main fuse and the remaining usage count of each of the plurality of sub fuses are equal to or less than a preset reference value and control a user interface provided in the vehicle to provide replacement notification information for the fuse having the remaining usage count equal to or less than the preset reference value.

5. The apparatus according to claim 1 , wherein the controller is configured to update usage history data of the main fuse and usage history data of each of the plurality of sub fuses.

6. A power distribution apparatus of a vehicle, the apparatus comprising:
a power input terminal configured to receive power;
a plurality of power output terminals;
a plurality of main fuses connected to the power input terminal, each main fuse of the plurality of main fuses to be connected to a respective one of a plurality of loads through a respective one of the plurality of power output terminals;
a plurality of sub fuses connected to the power input terminal;
a switching circuit provided between the plurality of sub fuses and the plurality of power output terminals; and
a controller configured to supply power to each of the plurality of loads through each of the plurality of main fuses in response to an operation signal of each of the plurality of loads and to control the switching circuit so that at least one of the plurality of sub fuses can be selectively connected to each of the plurality of loads, wherein the controller is configured to select the at least one of the plurality of sub fuses to be connected to the each of the plurality of loads based on a remaining usage count of each of the plurality of main fuses and a remaining usage count of each of the plurality of sub fuses.

7. The apparatus according to claim 6 , wherein the controller is configured to calculate the remaining usage count for each fuse in each set of a plurality of sets, each set including at least one of the plurality of main fuses and at least one of the plurality of sub fuses, and to select the at least one of the plurality of sub fuses based on the set among the plurality of sets having the sum of calculated remaining usage count for each fuse that is the maximum.

8. The apparatus according to claim 6 , wherein the controller is configured to calculate the remaining usage count of each of the plurality of main fuses and the remaining usage count of each of the plurality of sub fuses based on usage history data of each of the plurality of main fuses, durability data of each of the plurality of main fuses, usage history data of each of the plurality of sub fuses, and durability data of each of the plurality of sub fuses.

9. The apparatus according to claim 8 , wherein the controller is configured to recalculate the remaining usage count of each of the plurality of main fuses and the remaining usage count of each of the plurality of sub fuses based on the minimum of the remaining operation time of each of some of the main fuses connected to some of the loads and the average operation time of each of the other main fuses connected to the other part of the loads when the other part of the loads may operate after some of the loads of the plurality of loads have been operated.

10. The apparatus according to claim 6 , wherein the controller is configured to calculate the remaining usage count of each of the plurality of main fuses and the remaining usage count of each of the plurality of sub fuses based on the minimum of the average operation time of each of the plurality of main fuses when the plurality of loads start operating simultaneously.

11. The apparatus according to claim 10 , wherein the controller is configured to recalculate the remaining usage count of each of the plurality of main fuses and the remaining usage count of each of the plurality of sub fuses based on the minimum of the remaining operation time of each of the plurality of main fuses connected to the load not terminated when the operation of a part of the plurality of loads is terminated.

12. The apparatus according to claim 6 , wherein the controller is configured to determine whether the remaining usage count of each of the plurality of main fuses and the remaining usage count of each of the plurality of sub fuses are equal to or less than a preset reference value and control a user interface provided in the vehicle to provide replacement notification information for the fuse having the remaining usage count equal to or less than the preset reference value.

13. The apparatus according to claim 6 , wherein the controller is configured to update usage history data of each of the plurality of main fuses and usage history data of each of the plurality of sub fuses.

14. A method for controlling a power distribution apparatus of a vehicle, the method comprising:
supplying power to a load through a main fuse connected to a power input terminal in response to an operation signal of the load connected to a power output terminal; and
controlling a switching circuit provided between a plurality of sub fuses and the power output terminal so that at least one of the plurality of sub fuses connected to the power input terminal is selectively connected to the load based on a remaining usage count of the main fuse and a remaining usage count of the plurality of sub fuses.

15.
