Abstract

An integrated driving assistance apparatus is provided, which is installed in a vehicle with a headlight, a turn signal light, and a side-view mirror. The integrated driving assistance apparatus includes a detector, an infrared emitter, an image sensor, and an image processor. The detector is configured to detect whether the headlight and the turn signal light are turned on or off respectively. The infrared emitter is located on the side-view mirror and irradiates infrared rays when the detector detects that the headlight is turned on. The image sensor is located on the side-view mirror for capturing an image of an area beside the vehicle. The image processor is coupled to the image sensor and the detector and configured to receive and process the image to generate a warning signal. When the detector detects that the turn signal light is turned off, the image processor processes the image for a lane deviation alarm, and when the detector detects that the turn signal light is turned on, the image processor processes the image for a blind spot detection alarm.

Claims

1. An integrated driving assistance apparatus installed in a vehicle with a headlight, a turn signal light, and a side-view mirror, the integrated driving assistance apparatus comprising:

a detector configured to detect whether the headlight and the turn signal light are turned on or off respectively;

an infrared emitter located on the side-view mirror, the infrared emitter irradiates infrared ray when the detector detects that the headlight is turned on;

an image sensor located on the side-view mirror for capturing an image of an area beside the vehicle; and

an image processor coupled to the image sensor and the detector, the image processor configured to receive and process the image to generate a warning signal;

wherein when the detector detects that the turn signal light is turned off, the image processor processes the image for a lane deviation alarm, and when the detector detects that the turn signal light is turned on, the image processor processes the image for a blind spot detection alarm.

2. The apparatus of claim 1, further comprising an indicator coupled to the image processor and configured to receive and show the warning signal.

3. The apparatus of claim 2, wherein the indicator is a liquid crystal display (LCD), an organic light emitting diode (OLED) display, a plasma display, or a cathode ray tube (CRT) display.

4. The apparatus of claim 3, wherein the indicator is located on a vehicle instrument panel.

5. The apparatus of claim 3, wherein the indicator is located on the side-view mirror.

6. The apparatus of claim 2, wherein the indicator comprises a projector configured to project the warning signal onto a front windshield of the vehicle.

7. The apparatus of claim 2, wherein the indicator is a horn.

8. The apparatus of claim 2, wherein the indicator is a vibrator.

9. The apparatus of claim 2, wherein the indicator receives the warning signal through a wireless transmission interface selected from the group consisting of Bluetooth, infrared, and wireless USB.

10. The apparatus of claim 2, wherein the indicator receives the warning signal through a wire transmission interface selected from the group consisting of USB, IEEE1394, and RS232.

11. The apparatus of claim 1, wherein the image sensor is a complementary metal oxide semiconductor (CMOS) image sensor or a charge coupled device (CCD) image sensor.

12. The apparatus of claim 1, wherein the image sensor is capable of capturing visible light and infrared.

13. The apparatus of claim 1, further comprising a drive unit connected to the image sensor for driving the image sensor to rotate or shift.

14. The apparatus of claim 13, wherein the drive unit further comprises a motor and a gear.

15. The apparatus of claim 1, wherein when the detector detects that the headlight is turned off, the infrared emitter is turned off.

16. The apparatus of claim 1, wherein the side-view mirror of the vehicle comprises a left-side-view mirror and a right-side-view mirror, and the integrated driving assistance apparatus further comprises:

two infrared emitters located on the left-side-view mirror and right-side-view mirror respectively; and

two image sensors located on the left-side-view mirror and right-side-view mirror respectively.

17. The apparatus of claim 16, wherein the turn signal light of the vehicle comprises a left turn signal light and a right turn signal light, and wherein when the detector detects that the right turn signal light is turned on, the infrared emitter and the image sensor located on the right-side-view mirror are turned on and the infrared emitter and the image sensor located on the left-side-view mirror are turned off.

18. The apparatus of claim 2, further comprising four ground image sensors coupled to the image processor for capturing a rearward ground image, a frontward ground image, a rightward ground image, and a leftward ground image.

19. The apparatus of claim 18, wherein the image processor receives the rearward ground image, the frontward ground image, the rightward ground image, and the leftward ground image, and generates a corresponding panoramic image.

20. The apparatus of claim 19, further comprising a storage configured to record the image captured by the image sensor, the rearward ground image, the frontward ground image, the rightward ground image, and the leftward ground image captured by the ground image sensors, or the corresponding panoramic image.

21. The apparatus of claim 19, wherein the vehicle comprises a gearshift, and when the detector detects that the gearshift is in a reverse position, the indicator shows the corresponding panoramic image.

22. The apparatus of claim 19, further comprising a Man-machine interface configured to receive a user'"'"'s input to control operation of the image processor and an on/off state of the infrared emitter.
