Abstract

A mobile carrier includes a carrier controller configured to check an amount of charge of a main battery of a vehicle through communication with a vehicle controller, to check an amount of charge of a carrier battery, to compare the amounts of charge of the main battery and the carrier battery when the carrier is installed in the vehicle and to control mutual charging of the main battery and the carrier battery.

First claim

What is claimed is:

1. A mobile carrier comprising:
a carrier body including:
carrier wheels for movement of the carrier body outside a vehicle;
a seat for seating of a passenger;
an operation unit for controlling the carrier or the vehicle in a state in which the passenger is seated on the seat; and
a carrier battery to provide driving energy to the carrier wheels; and

a carrier controller configured to check an amount of charge of a main battery of the vehicle through communication with a vehicle controller, to check an amount of charge of the carrier battery, to compare the amounts of charge of the main battery and the carrier battery when the mobile carrier is installed in the vehicle, and to control mutual charging of the main battery and the carrier battery,
wherein, when a destination of the vehicle is input through the carrier controller or the vehicle controller, the carrier controller determines whether the vehicle is capable of traveling to the destination with the amount of charge of the main battery of the vehicle, and
wherein, when the destination of the vehicle is input to the vehicle controller, information on the destination of the vehicle is transmitted to the carrier controller through communication.

2. The mobile carrier according to claim 1 , wherein the mutual charging of the main battery and the carrier battery is performed through a wireless charging module when the mobile carrier is installed in the vehicle.

3. The mobile carrier according to claim 2 , wherein the carrier controller performs control to start the mutual charging of the main battery and the carrier battery when the mobile carrier is installed at a specific position in an internal space of the vehicle.

4. The mobile carrier according to claim 1 , wherein the mutual charging of the main battery and the carrier battery is performed through a wired charging module when the carrier is installed in the vehicle.

5. The mobile carrier according to claim 4 , wherein the carrier controller performs control to start the mutual charging of the main battery and the carrier battery by connecting the carrier body with the vehicle through the wired charging module, when the carrier is installed at a specific position in an internal space of the vehicle.

6. The mobile carrier according to claim 1 , wherein the carrier controller performs control to charge the carrier battery through the main battery when the amount of charge of the main battery is equal to or greater than a predetermined percentage.

7. The mobile carrier according to claim 6 , wherein the carrier controller performs control to charge the carrier battery through the main battery of the vehicle when the amount of charge of the carrier battery is equal to or less than a predetermined percentage.

8. The mobile carrier according to claim 1 , wherein the carrier controller performs control to charge the carrier battery through the main battery when the amount of charge of the carrier battery is equal to or less than a predetermined percentage.

9. The mobile carrier according to claim 1 , wherein, when the carrier controller determines that the vehicle is not capable of traveling to the destination with the amount of charge of the main battery, the carrier controller performs control to charge the main battery through the carrier battery.

10. The mobile carrier according to claim 1 , wherein the carrier battery is detachable from the carrier body and is replaceable.
