Abstract

A driving control system of a vehicle sets a target speed as an automatic setting speed when the driving control system is an automatic speed setting mode, changes a speed setting mode to a manual speed setting mode when a speed change input is received in the automatic speed setting mode, sets the target speed as a manual setting speed when the driving control system is a manual speed setting mode, changes the manual setting speed depending on the speed change input when the speed change input is received in the manual speed setting mode, and changes the speed setting mode to the automatic speed setting mode when the manual setting speed coincides with the automatic setting speed in the manual speed setting mode.

Claims

1. A driving control system of a vehicle, comprising:

a speed setting unit configured to set a target speed as one of an automatic setting speed and a manual setting speed depending on a speed setting mode;

a driving control unit configured to control a driving speed of the vehicle depending on the target speed set by the speed setting unit;

a first input unit configured to receive a speed change input; and

a mode setting unit configured to change the speed setting mode to a manual speed setting mode when receiving the speed change input in an automatic speed setting mode, and to change the speed setting mode to the automatic speed setting mode when the manual setting speed coincides with the automatic setting speed in the manual speed setting mode.

2. The driving control system of a vehicle according to claim 1, wherein when the driving control system is enabled, the mode setting unit changes the speed setting mode to the automatic speed setting mode.

3. The driving control system of a vehicle according to claim 1, wherein when the speed setting mode is changed to the manual speed setting mode, the speed setting unit sets a first manual setting speed to be equal to the automatic setting speed.

4. The driving control system of a vehicle according to claim 1, wherein the driving control system is enabled when the vehicle enters a main line of an express highway and is disabled when the vehicle deviates from the main line of the express highway.

5. The driving control system of a vehicle according to claim 1, further comprising:

a second input unit configured to receive a mode change input,

wherein when receiving the mode change input, the mode setting unit changes the speed setting mode depending on the received mode change input.

6. The driving control system of a vehicle according to claim 1, wherein the first input unit is a steering wheel switch which is positioned at a steering wheel of the vehicle, and

a current manual setting speed is increased or decreased depending on the speed change input received through the steering wheel switch in the manual speed setting mode.

7. The driving control system of a vehicle according to claim 1, wherein the automatic setting speed is changed depending on a speed limit of a driving road of the vehicle and the manual setting speed is changed depending on the speed change input received in the manual speed setting mode.

8. The driving control system of a vehicle according to claim 7, further comprising:

an acquisition unit configured to monitor the speed limit,

wherein the acquisition unit acquires the speed limit based on a position of the vehicle determined by navigation of the vehicle or detects the speed limit from a traffic sign recognized by a camera attached to the vehicle.

9. The driving control system of a vehicle according to claim 1, further comprising:

a display unit configured to display the target speed,

wherein the display unit displays the target speed with different colors depending on the speed setting mode.

10. A method for changing a speed setting mode in a driving control system of a vehicle, comprising:

when an automatic speed setting mode is enabled in the driving control system, setting a target speed as an automatic setting speed;

when a speed change input is received in the automatic speed setting mode, changing the speed setting mode to a manual speed setting mode;

when the manual speed setting mode is enabled in the driving control system, setting the target speed as a manual setting speed;

when the speed change input is received in the manual speed setting mode, changing the manual setting speed depending on the speed change input; and

when the manual setting speed coincides with the automatic setting speed in the manual speed setting mode, changing the speed setting mode to the automatic speed setting mode.

11. The driving control method for a vehicle according to claim 10, wherein the automatic setting speed is changed depending on a speed limit of a driving road of the vehicle.

12. The driving control method for a vehicle according to claim 10, further comprising:

when the driving control system is enabled, changing the speed setting mode to the automatic speed setting mode.

13. The driving control method for a vehicle according to claim 10, wherein when the speed setting mode is changed to the manual speed setting mode, a first manual setting speed is set to be equal to the automatic setting speed.

14. The driving control method for a vehicle according to claim 10, further comprising:

when the vehicle enters a main line of an express highway, enabling the driving control system; and

when the vehicle deviates from the main line of the express highway, disabling the driving control system.

15. The driving control method for a vehicle according to claim 10, further comprising:

when a mode change input is received, changing the speed setting mode depending on the received mode change input.

16. The driving control method for a vehicle according to claim 10, wherein the speed change input is received through a steering wheel switch which is positioned at a steering wheel of the vehicle and a current manual setting speed is increased or decreased depending on the speed change input received through the steering wheel switch in the manual speed setting mode.

17. The driving control method for a vehicle according to claim 11, wherein the speed limit of the driving road is acquired from road information depending on a position of the vehicle using navigation of the vehicle or is detected from a recognized sign using a camera attached to the vehicle.

18. The driving control method for a vehicle according to claim 10, further comprising:

displaying the target speed,

wherein a color of the target speed is changed depending on the speed setting mode.
