Abstract

A driving support apparatus includes an output unit installed in a steering wheel that outputs steer information about a rotation operation of the steering wheel to the driver through the output unit. By providing the driver with steer information from the output unit in the steering wheel, the driver may recognize the contents of the output of the steer information. Further, since the steer information has a high priority for the driver due to its direct relevance to movement and a travel direction of the vehicle, providing such high priority steer information in an easily-recognizable manner improves driver awareness or readiness to recognize lower-priority information. Thus, information overload by the driver caused by information from various driving support techniques is prevented.

Claims

1. A driving support apparatus installed in a vehicle and supporting a driver driving the vehicle, the driving support apparatus comprising:

a steering wheel controlling a directional movement of the vehicle;

a steer information obtain unit obtaining steer information about a rotation operation of the steering wheel; and

a steer information output unit installed in the steering wheel and outputting the steer information to the driver.

2. The driving support apparatus of claim 1, wherein

the steer information obtain unit obtains the steer information by detecting a rotation operation of the steering wheel that is performed by the driver.

3. The driving support apparatus of claim 1, wherein

the steer information includes a rotation direction of the steering wheel.

4. The driving support apparatus of claim 1, wherein

the steer information includes a rotation speed of the steering wheel.

5. The driving support apparatus of claim 1, wherein

the steer information output unit visually outputs the steer information to a visual sense of the driver.

6. The driving support apparatus of claim 1, wherein

the steer information output unit tactily outputs the steer information to a tactile sense of the driver.

7. The driving support apparatus of claim 1 further comprising:

a drive unit rotationally driving the steering wheel; and

a drive controller controlling the drive unit to rotationally drive the steering wheel, wherein

the steer information obtain unit obtains the steer information based on a control amount of the drive unit that is controlled by the drive controller.

8. The driving support apparatus of claim 7 further comprising:

a manual driving state in which the driver performs the rotation operation of the steering wheel;

an automatic driving state in which the drive unit performs the rotational drive of the steering wheel; and

a determination unit determining whether the vehicle is in the manual driving state or the automatic driving state, wherein

when in the manual driving state, the steer information output unit tactily outputs the steer information to a tactile sense of the driver, and

when in the automatic driving state, the steer information output unit visually outputs the steer information to a visual sense of the driver.

9. The driving support apparatus of claim 8, wherein

when in the automatic driving state, the steer information output unit outputs the steer information to the driver prior to the drive unit rotationally driving the steering wheel.
