Abstract

A vehicle may include an engine; a transmission; an accelerator pedal position sensor; a steering wheel; a steering angle sensor; and a processor configured to control the engine according to a position of an accelerator pedal detected by the accelerator pedal position sensor and to shift the transmission to a neutral state when a position of the accelerator pedal coincides with a reference position while the transmission is in a driving state, wherein the processor shifts the transmission to a driving state when a steering angle of the steering wheel detected by the steering angle sensor is equal to or greater than a reference angle while the transmission is in a neutral state.

First claim

What is claimed is:

1. A vehicle comprising:
an engine;
a transmission;
an accelerator pedal position sensor;
a steering wheel;
a steering angle sensor; and
a processor configured to control the engine according to a position of an accelerator pedal detected by the accelerator pedal position sensor, and shift the transmission to a neutral state when the position of the accelerator pedal coincides with a reference position while the transmission is in a driving state,
wherein the processor is configured to shift the transmission to the driving state when a steering angle of the steering wheel detected by the steering angle sensor is equal to or greater than a reference angle while the transmission is in the neutral state.

2. The vehicle of claim 1 , further including a multi-function switch,
wherein the processor is configured to shift the transmission to the driving state when the multi-function switch is disposed in a direction-indicating position while the transmission is in the neutral state.

3. The vehicle of claim 1 , further including an image sensor configured to capture an image of a front side of the vehicle,
wherein the processor is configured to shift the transmission to the driving state when the steering angle of the steering wheel is equal to or greater than the reference angle and when a lane departure of the vehicle is detected on a basis of the image captured by the image sensor while the transmission is in the neutral state.

4. The vehicle of claim 1 , further including an image sensor configured to capture an image of a front side of the vehicle,
wherein the processor is configured to maintain the transmission in the neutral state when a violation of a centerline of the vehicle is detected on a basis of the image captured by the image sensor while the transmission is in the neutral state.

5. The vehicle of claim 1 , further including a rear side radar sensor configured to emit radio waves rearwards of the vehicle,
wherein the processor is configured to maintain the transmission in the neutral state when an obstacle disposed at a rear side of the vehicle is detected on a basis of reflective radio waves received by the rear side radar sensor while the transmission is in the neutral state.

6. The vehicle of claim 1 , further including a front side radar sensor configured to emit radio waves forwards of the vehicle,
wherein the processor is configured to shift the transmission to the driving state when another vehicle disposed in a range of a first reference distance of the vehicle is detected on a basis of reflective radio waves received by the front side radar sensor with the transmission being in the neutral state.

7. The vehicle of claim 6 , wherein the processor is configured to shift the transmission to the driving state when another vehicle disposed outside a range of a second reference distance of the vehicle, which is greater than the first reference distance, is detected on a basis of the reflective radio waves received by the front side radar sensor with the transmission being in the neutral state.

8. The vehicle of claim 7 , wherein the processor is configured to shift the transmission to the driving state when another vehicle is detected to have a relative speed less than a first reference speed on a basis of the reflective radio waves received by the front side radar sensor while the transmission is in the neutral state.

9. The vehicle of claim 8 , wherein the processor is configured to shift the transmission to the driving state when another vehicle is detected to have a relative speed greater than a second reference speed, which is greater than the first reference speed, on a basis of the reflective radio waves received by the front side radar sensor while the transmission is in the neutral state.

10. A method of controlling a vehicle including an engine, a transmission, a steering wheel, and a processor, the method comprising:
controlling, by the processor, the engine according to a position of an accelerator pedal;
shifting, by the processor, the transmission to a neutral state when a position of the accelerator pedal coincides with a reference position while the transmission is in a driving state; and
shifting, by the processor, the transmission to the driving state when a steering angle of the steering wheel is equal to or greater than a reference angle while the transmission is in the neutral state.

11. The method of claim 10 , further including:
shifting, by the processor, the transmission to the driving state when a multi-function switch is disposed in a direction-indicating position while the transmission is in the neutral state.

12. The method of claim 10 , further including:
shifting, by the processor, the transmission to the driving state when a lane departure of the vehicle is detected on a basis of a front view image captured by an image sensor while the transmission is in the neutral state.

13. The method of claim 10 , further including:
maintaining, by the processor, the transmission in the neutral state when a violation of a centerline of the vehicle is detected on a basis of a front view image captured by an image sensor while the transmission is in the neutral state.

14. The method of claim 10 , further including:
maintaining, by the processor, the transmission in the neutral state when an obstacle disposed at a rear side of the vehicle is detected on a basis of reflective radio waves received by a rear side radar sensor while the transmission is in the neutral state.

15. The method of claim 10 , further including:
shifting, by the processor, the transmission to the driving state when another vehicle disposed in a range of a first reference distance of the vehicle is detected on a basis of reflective radio waves received by a front side radar sensor while the transmission is in the neutral state.

16. The method of claim 15 , further including:
shifting, by the processor, the transmission to the driving state when another vehicle disposed outside a range of a second reference distance of the vehicle, which is greater than the first reference distance, is detected on a basis of the reflective radio waves received by the front side radar sensor while the transmission is in the neutral state.

17. The method of claim 16 , further including:
shifting, by the processor, the transmission to the driving state when another vehicle is detected to have a relative speed less than a first reference speed on a basis of the reflective radio waves received by the front side radar sensor while the transmission is in the neutral state.

18. The method of claim 17 , further including:
shifting, by the processor, the transmission to the driving state when another vehicle is detected to have a relative speed greater than a second reference speed, which is greater than the first reference speed, on a basis of the reflective radio waves received by the front side radar sensor while the transmission is in the neutral state.

19. A vehicle comprising:
an engine;
a transmission;
an accelerator pedal position sensor;
a multi-function switch;
a direction indicating lamp; and
a processor configured to control the engine according to a position of an accelerator pedal detected by the accelerator pedal position sensor, and shift the transmission to a neutral state when a position of the accelerator pedal coincides with a reference position while the transmission is in a driving state,
