Abstract

Provided are a control method and system for a host vehicle. The control method in which the host vehicle has adaptive cruise control (ACC) includes selecting a lane or another vehicle as a target lane or a target vehicle for the ACC according to selection of a driver; when the lane is selected, controlling the ACC to cause the host vehicle to travel in the selected target lane; and when the other vehicle is selected, controlling the ACC to cause the host vehicle to follow the selected target vehicle, wherein the controlling includes changing the lane when the target lane or a lane of the target vehicle does not correspond to a lane of the host vehicle.

Claims

1. A control method for a host vehicle having adaptive cruise control (ACC), the control method comprising:

selecting a lane or another vehicle as a target lane or a target vehicle for the ACC according to selection of a driver;

when the lane is selected, controlling the ACC to cause the host vehicle to travel in the selected target lane; and

when the other vehicle is selected, controlling the ACC to cause the host vehicle to follow the selected target vehicle,

wherein the controlling includes changing the lane when the target lane or a lane of the target vehicle does not correspond to a lane of the host vehicle.

2. The control method of claim 1, wherein, when the selected target lane is the lane in which the host vehicle travels or the selected target vehicle is another vehicle traveling ahead of the host vehicle in the same lane, the ACC is continuously performed using the other vehicle traveling ahead of the host vehicle.

3. The control method of claim 1, wherein the lane is changed at a predetermined distance from an obstacle to the host vehicle under the control of a speed and a steering angle of the host vehicle.

4. The control method of claim 3, further comprising controlling the ACC to change the lane and select another vehicle traveling ahead of the host vehicle as a preceding vehicle when the selected target lane is not the lane in which the host vehicle travels.

5. A control system for a vehicle having adaptive cruise control (ACC), the control system comprising:

a user interface configured to receive input of a driver; and

a control unit that configured to control the ACC to select a lane or another vehicle as a target lane or a target vehicle according to the input of the driver, to drive the host vehicle in the selected target lane, or to follow the selected target vehicle.

6. The control system of claim 5, wherein, when the selected target lane is in a lane in which the host vehicle travels or the selected target vehicle is another vehicle traveling ahead of the host vehicle in the same lane, the control unit continuously performs the ACC using the other vehicle traveling ahead of the host vehicle.

7. The control system of claim 6, wherein:

the control unit is configured to change the lane when the selected target lane or the selected target vehicle does not correspond to the lane in which the host vehicle travels; and

the lane is changed at a predetermined distance form an obstacle to the host vehicle under the control of a speed and steering of the host vehicle.

8. The control system of claim 7, wherein, when the selected target lane is not the lane in which the host vehicle travels, the lane is changed, and the other vehicle traveling ahead of the host vehicle is selected as a preceding vehicle.

9. The control system of claim 5, wherein the user interface includes a touch screen that receives and displays the input of the driver.

15. The control system of claim 6, wherein the user interface includes a touch screen that receives and displays the input of the driver.

16. The control system of claim 7, wherein the user interface includes a touch screen that receives and displays the input of the driver.

17. The control system of claim 8, wherein the user interface includes a touch screen that receives and displays the input of the driver.

10. A control system for a vehicle having adaptive cruise control (ACC), the control system comprising:

an input unit configured to receive input of a driver;

a display unit configured to display the input of the driver; and

a control unit that configured to control the ACC to select a lane or another vehicle as a target lane or a target vehicle according to the input of the driver, to drive the host vehicle in the selected target lane, or to follow the selected target vehicle.

11. The control system of claim 10, wherein, when the selected target lane is in a lane in which the host vehicle travels or the selected target vehicle is another vehicle traveling ahead of the host vehicle in the same lane, the control unit continuously performs the ACC using the other vehicle traveling ahead of the host vehicle.

12. The control system of claim 11, wherein:

the control unit is configured to change the lane when the selected target lane or the selected target vehicle does not correspond to the lane in which the host vehicle travels; and

the lane is changed at a predetermined distance from an obstacle to the host vehicle under the control of a speed and a steering angle of the host vehicle.

13. The control system of claim 12, wherein, when the selected target lane is not the lane in which the host vehicle travels, the lane is changed, and the other vehicle traveling ahead of the host vehicle is selected as a preceding vehicle.

14. The control system of claim 10, wherein the input unit is configured to include a turn signal or a touch screen.

18. The control system of claim 11, wherein the input unit is configured to include a turn signal or a touch screen.

19. The control system of claim 12, wherein the input unit is configured to include a turn signal or a touch screen.

20. The control system of claim 13, wherein the input unit is configured to include a turn signal or a touch screen.
