Abstract

A method for controlling an electricity generation mode of a vehicle includes detecting an idle condition of an engine. An electricity generation mode is performed in which a generator generates an electricity. An idle RPM is increased in the electricity generation mode. An managing mode is entered if the electricity generation mode time elapses a reference time. An engine RPM is increased or decreased for a predetermined time in the managing mode.

Claims

1. A method for controlling an electricity generation mode of a vehicle, the method comprising steps of:

detecting an idle condition of an engine;

generating an electricity by a generator in an electricity generation mode;

increasing an idle revolutions per minute (RPM) in the electricity generation mode;

entering an electricity generation managing mode if an electricity generation mode time elapses a reference time; and

increasing or decreasing an engine RPM for a predetermined time in the electricity generation managing mode.

2. The method of claim 1, wherein the electricity generation mode is performed in a D (drive) condition, a R (rear) condition, a N (neutral) condition, or a P (parking) condition of a transmission, and the engine RPM is changed according to a condition of the transmission.

3. The method of claim 1, wherein if it is determined that the engine RPM exceeds a reference RPM in the electricity generation mode, an accumulation time is reset to 0 (zero).

4. The method of claim 1, wherein the electricity generation mode or the electricity generation managing mode is selected by an electricity generation mode switch.

5. The method of claim 1, wherein if it is determined that a total accumulation time of the electricity generation managing mode exceeds a reference accumulation time, an emergency light is turned on.

6. The method of claim 1, wherein if it is determined that a total accumulation time of the electricity generation managing mode exceeds a reference accumulation time, a replacement signal for an engine component is generated according to the total accumulation time of the managing mode.

7. A system for controlling an electricity generation mode of a vehicle, the system comprising:

an engine;

an electricity generation mode switch;

a generator configured to generate an electricity;

a battery having an inner side battery that is disposed inside the vehicle and an outer side battery that is disposed outside the vehicle; and

a controller configured to control an engine RPM based on a driving condition of the engine of an operation of the electricity generation mode switch.
