Abstract

A lane departure warning system and method in combination with a driving behavior are provided. The system is disposed on a vehicle, and includes: at least one first information nation capture unit, for capturing environment information around the vehicle; at least one second information capture unit, disposed in the vehicle, for capturing in-vehicle image information; a processing unit, electrically connected to the first information capture unit and the second information capture unit, where the processing unit uses an environment determining unit to determine an environment condition of the vehicle according to the environment information, so that the processing unit performs an operation process according to the environment information of the first information capture unit and the in-vehicle image information of the second information capture unit, so as to generate an alarm signal; and a warning unit, for receiving the alarm signal to generate a warning action.

Claims

1. A lane departure warning system in combination with a driving behavior, disposed on a vehicle, comprising:

an environment determining unit;

at least one first information capture unit, for capturing environment information around the vehicle;

at least one second information capture unit, disposed in the vehicle, for capturing in-vehicle image information;

a processing unit, electrically connected to the at least one first information capture unit and the at least one second information capture unit, wherein the processing unit uses the environment determining unit to determine an environment condition of the vehicle according to the environment information, so that the processing unit performs an operation process according to the environment information of the at least one first information capture unit and the in-vehicle image information of the at least one second information capture unit, so as to genera an alarm signal; and

a warning unit, for receiving the alarm signal to generate a warning action.

2. The lane departure warning system in combination with a driving behavior according to claim 1, wherein the first information capture unit is a camera.

3. The lane departure warning system in combination with a driving behavior according to claim 1, wherein the first information capture unit captures and outputs several pieces of image data, and the environment information at least comprises a lane line.

4. The lane departure warning system in combination with a driving behavior according to claim 1, wherein the second information capture unit is a camera.

5. The lane departure warning system in combination with a driving behavior according to claim 1, wherein the warning unit is an alarm.

6. The lane departure warning system in combination with a driving behavior according to claim 1, wherein the warning unit is a display.

7. The lane departure warning system in combination with a driving behavior according to claim 1, further comprising a speed sensing unit, for sensing a driving speed of the vehicle, and outputting a speed signal for the processing unit to perform the operation process.

8. A lane departure warning method in combination with a driving behavior, applicable to a vehicle, comprising the following steps:

capturing environment information around the vehicle by using at least one first information capture unit;

capturing in-vehicle image information by using at least one second information capture unit disposed in the vehicle;

electrically connecting a processing unit to the at least one first information capture unit and the at least one second information capture unit;

determining an environment condition of the vehicle by using an environment determining unit according to the environment information, so that the processing unit performs an operation process according to the environment information of the at least one first information capture unit and the in-vehicle image information of the at least one second information capture unit, so as to generate an alarm signal; and

receiving the alarm signal by a warning unit to generate a warning action.

9. The lane departure warning method in combination with a driving behavior according to claim 8, wherein the step of capturing environment information around the vehicle by using at least one first information capture unit further comprises:

capturing and outputting several pieces of image data by the first information capture unit, wherein the environment information at least comprises a lane line.

10. The lane departure warning method in combination with a driving behavior according to claim 8, wherein the step of the processing unit performing an operation process according to the environment information of the at least one first information capture unit and the in-vehicle image information of the at least one second information capture unit, so as to generate an alarm signal further comprises:

providing a speed sensing unit to sense a driving speed of the vehicle, and output a speed signal for the processing unit to perform the operation process.
