Abstract

Disclosed is a driving assistance apparatus that includes: a sensor configured to sense information received from at least one of a camera configured to speed limit sign information, a navigation system configured to receive GPS information so as to sense road information for a road on which a vehicle is traveling, a vehicle speed sensor configured to sense vehicle speed information, and an input sensor configured to sense whether an input exists or not; a recognizing unit configured to recognize a speed limit based on at least one of the limit speed sign information and the road information; and a control unit configured to control in such a manner that the traveling speed of the vehicle according to the vehicle speed information does not exceed the speed limit. When it is sensed that an input exists, the control is not performed.

Claims

1. A driving assistance apparatus comprising:

a sensing unit configured to receive and sense information from at least one of a camera configured to sense speed limit sign information, a navigation system configured to sense road information for a road on which a vehicle is traveling by receiving GPS information, a vehicle speed sensor configured to sense vehicle speed information, and an input sensor configured to sense whether an input exists or not;

a recognizing unit configured to recognize a speed limit based on at least one of the speed limit sign information and the road information; and

a control unit configured to control a vehicle in such a manner that the traveling speed of the vehicle according to the vehicle speed information does not exceed the recognized speed limit, wherein, when it is sensed that an input exists, the control unit does not perform the control.

2. The driving assistance apparatus of claim 1, wherein the input sensor senses that the input exists when the input device operates, when a pressed amount of an acceleration pedal of the vehicle is equal to or larger than a preset value, or when the acceleration pedal is continuously pressed for a preset critical time.

3. The driving assistance apparatus of claim 1, wherein the road information includes regional information including a downtown, a school zone, and a residential area, and also includes overspeed regulation information.

4. The driving assistance apparatus of claim 3, further comprising:

a selection unit configured to generate selected information when the regional information or the overspeed regulation information is selected,

wherein the control unit controls the vehicle in such a manner that the traveling speed of the vehicle does not exceed only the speed limit based on the selected information.

5. The driving assistance apparatus of claim 1, wherein the control unit limits an output signal obtained when an acceleration pedal of the vehicle is pressed to a predetermined amount such that the traveling speed of the vehicle does not exceed the speed limit.

6. The driving assistance apparatus of claim 1, wherein the control unit limits an output signal obtained when an acceleration pedal of the vehicle is pressed such that the traveling speed of the vehicle does not exceed the speed limit.

7. The driving assistance apparatus of claim 1, wherein the navigation system updates the road information using a portable phone.

8. The driving assistance apparatus of claim 1, further comprising:

a notification providing unit configured to provide a notification to a driver,

wherein the notification providing unit provides at least one of a notification as to the vehicle speed information, a notification as to the speed limit, and a notification as to a fact that the vehicle is controlled.

9. The driving assistance apparatus of claim 1, further comprising:

a generating unit configured to request an order to limit the traveling speed of the vehicle from a driver when the traveling speed of the vehicle exceeds the speed limit, and to generate order information requested thereby,

wherein, when the order information to limit the traveling speed of the vehicle is generated, the control unit controls the vehicle in such a manner that the traveling speed of the vehicle does not exceed the speed limit.

10. The driving assistance apparatus of claim 9, wherein, when the traveling speed of the vehicle exceeds a sum of the speed limit and a preset critical speed, the generating unit requests the order from the driver.

11. A driving assistance method comprising:

a sensing step of sensing at least one of speed limit sign information obtained using a camera, a road information obtained using a navigation system that receives GPS information, vehicle speed information obtained using a vehicle speed sensor, and input information obtained using an input sensor;

a recognizing step of recognizing a speed limit based on at least one of the speed limit sign information and the road information; and

a control step of controlling the vehicle in such a manner that the traveling speed of the vehicle does not exceed the recognized speed limit, wherein, when input information is sensed, the control is not performed.
