Abstract

A driving safety system for a vehicle includes a housing, a camera positioned on the housing, and a controller positioned on the housing and electrically coupled to the camera. The controller includes a plurality of modules whereby the camera captures images of the scene in front of the vehicle and an image identification module identifies a traffic light state and a value of a countdown timer in real time from the captured images and sends a corresponding signal to the micro control unit, then the micro control unit will warn the driver as to the states of the traffic lights and countdown timer. A vehicle using the driving safety system is also disclosed.

Claims

1. A driving safety system configured to operate in a vehicle, the driving safety system comprising:

a housing;

a camera positioned on the housing for capturing images of a scene in front of the vehicle;

a controller positioned on the housing and electrically coupled to the camera and comprising;

a micro control unit configured to receive captured images from the camera,

a storage module electrically coupled to the micro control unit and configured to receive the captured images from the micro control unit,

an image identification module electrically coupled to the micro control unit and the storage unit and being configured to identify a traffic light state and a value of a countdown timer from the storage images in real time,

a warning module electrically coupled to the micro control unit,

wherein the image identification module sends a signal to the micro control device upon a determination that a traffic light in an image is red and a value of the countdown timer is less than a preset value and the micro control unit sending a signal to the warning module to cause the warning module to emit a warning.

2. The driving safety system of claim 1, wherein the warning module comprises a vibrator and a buzzer, the vibrator and the buzzer are positioned on the housing and electrically coupled with the micro control unit.

3. The driving safety system of claim 1, wherein the housing comprises a first surface, the driving safety system further comprises a display mounted on the first surface and electrically coupled to the micro control unit for displaying a warning signal and final countdown numbers of the countdown timer.

4. The driving safety system of claim 1, further comprising a wide angle lens assembled to the camera for widely grabbing images being front of the vehicle.

5. The driving safety system of claim 1, further comprising a rechargeable battery electrically coupled with the camera and the micro control unit.

6. The driving safety system of claim 1, further comprising a charging wire for coupling between the rechargeable battery and a cigar lighter of the vehicle.

7. A driving safety system for a vehicle, comprising:

a housing;

a camera positioned on the housing for capturing images of a scene in front of the vehicle; and

a controller positioned on the housing and electrically coupled to the camera, the controller comprising a micro control unit, a storage module, an image identification module, and a warning module, the micro control unit electrically coupled with the storage module, the image identification module, and the warning module,

wherein the micro control unit is configured for receiving the images from the camera and sending the images to the storage module, the image identification module is electrically coupled with the storage module for identifying a traffic light state and a value of a countdown timer from the images in real time, and sending a corresponding signal to the micro control unit, then the micro control unit will drive the warning module to send out a warning signal as to the state of the traffic lights and countdown timer.

8. The driving safety system of claim 7, wherein the warning module comprises a vibrator and a buzzer, the vibrator and the buzzer are positioned on the housing and electrically coupled with the micro control unit.

9. The driving safety system of claim 7, wherein the housing comprises a first surface, the driving safety system further comprises a display mounted on the first surface and electrically coupled to the micro control unit for displaying a warning signal and final countdown numbers of the countdown timer.

10. The driving safety system of claim 7, further comprising a wide angle lens assembled to the camera for widely grabbing images being front of the vehicle.

11. The driving safety system of claim 7, further comprising a rechargeable battery electrically coupled with the camera and the micro control unit.

12. The driving safety system of claim 7, further comprising a charging wire for coupling between the rechargeable battery and a cigar lighter of the vehicle.

13. The driving safety system of claim 7, wherein the image identification module comprises an image extracting unit, an image denoising unit, an image filtering unit, and an image matching unit, the image extracting unit is configured for extracting imagines of traffic lights and countdown timer out of the full amount of data received from the storage module, the image denoising unit and the image filtering unit is configured for image denoising and filtering, and the image matching unit can be configured for determining state of the traffic light and the countdown timer from the processed images by the image denoising unit and the image filtering unit, and sending a signal to the micro control unit according to corresponding state of the traffic light and the countdown timer.

14. A vehicle comprising:

a vehicle body;

a front windshield positioned on the vehicle body; and

a driving safety system positioned in the vehicle body adjacent to the front windshield, the driving safety system comprising;

a housing;

a camera positioned on the housing for capturing images of a scene in front of the vehicle; and

a controller positioned on the housing and electrically coupled to the camera, the controller comprising a micro control unit, a storage module, an image identification module, and a warning module, the micro control unit electrically coupled with the storage module, the image identification module, and the warning module,

wherein the micro control unit is configured for receiving the images from the camera and sending the images to the storage module, the image identification module is electrically coupled with the storage module for identifying a traffic light state and a value of a countdown timer from the images in real time, and sending a corresponding signal to the micro control unit, then the micro control unit will drive the warning module to send out a warning signal as to the state of the traffic lights and countdown timer.
