Abstract

An embodiment vehicle includes a battery, a switch configured to identify whether a state of a power of the vehicle is in a normal state or an abnormal state by monitoring the power of the vehicle and to control a supply of a battery power of the battery based on the state of the power being in the abnormal state, and a controller configured to control the vehicle based on the supply of the battery power.

First claim

What is claimed is:

1. A vehicle comprising:
a battery;
a switch configured to:
identify whether a state of a power of the vehicle is in a normal state or an abnormal state by monitoring the power of the vehicle; and
control a supply of a battery power of the battery based on the state of the power being in the abnormal state;

a controller configured to control the vehicle based on the supply of the battery power; and
a voltage converter configured to supply the power of the vehicle,
wherein the switch is further configured to:
identify a voltage of the voltage converter;
identify whether the state of the power is in the normal state or the abnormal state based on the voltage of the voltage converter; and
control the battery power of the battery to be supplied to the controller.

2. The vehicle of claim 1 , wherein the switch is further configured to:
identify that the state of the power is in the abnormal state based on the voltage of the voltage converter being out of a preset reference voltage range for more than a predetermined number of times.

3. The vehicle of claim 1 , wherein the switch is further configured to:
identify whether an ignition power or an accessory power of the battery is supplied; and
identify that the state of the power of the vehicle is in the abnormal state based on the ignition power and the accessory power of the battery not being supplied.

4. The vehicle of claim 3 , wherein the switch is further configured to:
identify that the state of the power of the vehicle is in the normal state based on the ignition power or the accessory power of the battery being supplied.

5. The vehicle of claim 1 , wherein the controller is further configured to:
control the vehicle in motion to pull over on a shoulder of a driving lane based on the battery power.

6. A method of controlling a vehicle, the method comprising:
identifying whether a state of a power of the vehicle is in a normal state or an abnormal state by monitoring the power of the vehicle;
controlling a battery power of a battery of the vehicle to be supplied to a controller based on the state of the power being in the abnormal state; and
controlling the vehicle in response to the battery power being supplied to the controller, wherein:
the power of the vehicle includes a power supplied from a voltage converter of the vehicle; and
identifying whether the state of the power is in the normal state or the abnormal state comprises:
identifying a voltage of the voltage converter; and
identifying whether the state of the power is in the normal state or the abnormal state based on the voltage of the voltage converter.

7. The method of claim 6 , wherein identifying whether the state of the power is in the normal state or the abnormal state further comprises:
identifying that the state of the power is in the abnormal state based on the voltage of the voltage converter being outside of a preset reference voltage range for more than a predetermined number of times.

8. The method of claim 6 , further comprising:
identifying whether an ignition power or an accessory power of the battery is supplied,
wherein identifying whether the state of the power is in the normal state or the abnormal state further comprises:
identifying that the state of the power of the vehicle is in the abnormal state based on the ignition power and the accessory power of the battery not being supplied.

9. The method of claim 8 , wherein identifying whether the state of the power is in the normal state or the abnormal state further comprises:
identifying that the state of the power of the vehicle is in the normal state based on the ignition power or the accessory power of the battery being supplied.

10. The method of claim 6 , wherein controlling the vehicle comprises controlling the vehicle in motion to pull over on a shoulder of a driving lane.

11. A method of controlling a vehicle, the method comprising:
determining whether a cause of an emergency state of the vehicle is an internal cause or an external cause;
in response to determining the cause of the emergency state is the internal cause, determining whether a power state of the vehicle is a normal state or an abnormal state;
in response to determining the power state of the vehicle is the abnormal state, controlling a battery power of a battery of the vehicle to be supplied to a controller; and
controlling the vehicle in response to the battery power being supplied to the controller,
wherein determining whether the power state of the vehicle is the normal state or the abnormal state comprises:
identifying a voltage of a voltage converter of the vehicle; and
determining the power state of the vehicle based on the voltage of the voltage converter.

12. The method of claim 11 , further comprising:
determining that the power state of the vehicle is the abnormal state based on the voltage of the voltage converter being outside of a preset reference voltage range for more than a predetermined number of times.

13. The method of claim 11 , further comprising:
determining whether an ignition power or an accessory power of the battery is supplied.

14. The method of claim 13 , further comprising:
determining that the power state of the vehicle is the abnormal state based on determining that the ignition power and the accessory power of the battery are not supplied.

15. The method of claim 13 , further comprising:
determining that the power state of the vehicle is the normal state based on determining that the ignition power or the accessory power of the battery is supplied.

16. The method of claim 11 , wherein controlling the vehicle comprises controlling the vehicle in motion to pull over on a shoulder of a driving lane.

17. The method of claim 11 , further comprising:
controlling an operation for coping with the emergency state in response to determining the cause of the emergency state of the vehicle is the external cause.
