engage the clutch to decelerate the vehicle speed when the vehicle reaches the stopping line with the first deceleration rate.

5. The vehicle driving control apparatus of claim 1 , wherein the controller is configured to:

receive lighting color information from a traffic information device;

determine whether the stopping line distance is within a predetermined distance when the lighting color of the traffic signal light is red based on the lighting color information; and

determine that the driving control condition is satisfied when the stopping line distance is within the predetermined distance.

6. The vehicle driving control apparatus of claim 1 , wherein:

the controller is configured to determine that the entry condition is satisfied when a position value of an accelerator pedal is a first predetermined value and a position value of a brake pedal is a second predetermined value.

7. The vehicle driving control apparatus of claim 1 , wherein the state detector comprises at least one of:

a speed detecting unit configured to detect the vehicle speed;

an accelerator pedal position sensor configured to detect a position value of the accelerator pedal; or

a brake pedal position sensor configured to detect a position value of the brake pedal.

8. A vehicle driving control method comprising:

determining whether an entry condition is satisfied based on state data;

determining a stopping line distance based on a difference between a vehicle and a stopping line when the entry condition is satisfied;

determining whether a lighting color of a traffic signal light positioned at the stopping line is red;

determining whether the stopping line distance is within a predetermined distance when the lighting color of the traffic signal light is red;

confirming a deceleration rate depending on a clutch engagement when the stopping line distance is within the predetermined distance;

determining a stop prediction position based on the deceleration rate; and

controlling a clutch based on the stop prediction position,

wherein determining the stop prediction position comprises:

when the clutch is engaged, determining a first stop prediction position based on a first deceleration rate; and

when the clutch is disengaged, determining a second stop prediction position based on a second deceleration rate.

9. The vehicle driving control method of claim 8 , wherein controlling the clutch comprises:

determining whether the first stop prediction position is a first predetermined position; and

engaging the clutch to decelerate a vehicle speed when the first stop prediction position is the first predetermined position,

wherein the first predetermined position is a position that a front portion of the vehicle is on the stopping line or crosses the stopping line.

10. The vehicle driving control method of claim 9 , wherein controlling the clutch comprises:

determining whether the second stop prediction position is a second predetermined position when the first stop prediction position is the second predetermined position; and

disengaging the clutch to decelerate the vehicle speed when the second stop prediction position is the second predetermined position,

wherein the second predetermined position is a position that the front portion of the vehicle is not on the stopping line and does not cross the stopping line.

11. The vehicle driving control method of claim 9 , wherein controlling the clutch comprises:

determining whether the second stop prediction position is a second predetermined position when the first stop prediction position is the second predetermined position;

disengaging the clutch to decelerate the vehicle speed when the second stop prediction position is the first predetermined position;

determining whether the vehicle reaches the stopping line with the first deceleration rate when the vehicle speed is decelerated; and

engaging the clutch to decelerate the vehicle speed when the vehicle reaches the stopping line with the first deceleration rate.

12. The vehicle driving control method of claim 8 , wherein determining the stopping line distance comprises:

receiving road guidance information from a route guidance device; and

determining the stopping line distance based on a vehicle position by using the road guidance information.

13. The vehicle driving control method of claim 8 , wherein determining whether the lighting color of the traffic signal light is red comprises:

receiving lighting color information from a traffic information device; and
