Abstract

An intelligent driving recording and inspection system is introduced for recording a car'"'"'s driving process and for a user to review the driving process in an intelligent manner. The system includes an image-capture unit for capturing image signals in the driving process; a sensing unit for generating event signals corresponding to all events encountered in the driving process, such as lane departure, close distance from a preceding car, changes in gravity sensing, and abnormalities shown in inside-car driving data; a processing unit for linking the event signals with and marking the same on corresponding image signals; a memory unit for storing the image signals and the event signals; and a inspection unit for a user to review the stored image signals marked with the event signals. Therefore, any event occurred in the driving process can be easily analyzed by reviewing the image signals having corresponding event signal marked thereon.

Claims

1. An intelligent driving recording and inspection system capable of recording a car'"'"'s whole driving process for a driver to review the driving process in an intelligent manner, comprising:

an image-capture unit for capturing image signals in the whole driving process;

a sensing unit being installed outside and/or inside the car for sensing all events encountered by the car in the driving process and generating an event signal corresponding to each of the sensed events;

a processing unit being electrically connected to the image-capture unit and the sensing unit; and

the processing unit linking the event signals with corresponding image signals and marking the event signals on the corresponding image signals; and

a memory unit being electrically connected to the processing unit for storing the event signals and the image signals thereon.

2. The intelligent driving recording and inspection system as claimed in claim 1, wherein the event signals are generated corresponding to different events sensed by at least one of a lane departure warning system, a forward collision warning system, a G-sensor and/or any inside-car driving data.

3. The intelligent driving recording and inspection system as claimed in claim 2, wherein the inside-car driving data include data about at least one of the stepping of an accelerator pedal by the driver, data about driving speed, data about the stepping of a brake pedal by the driver, data about fuel consumption of the car, data about turns made by the driver and/or data about the use of directional and other lights of the car by the driver.

4. The intelligent driving recording and inspection system as claimed in claim 1, further comprising a positioning unit being electrically connected to the processing unit;

the positioning unit generating a position signal corresponding to the car'"'"'s each position, and the processing unit linking the position signals with corresponding image signals and marking the position signals on the corresponding image signals.

5. The intelligent driving recording and inspection system as claimed in claim 4, wherein the memory unit stores the whole driving process to form a driving track of the car.

6. The intelligent driving recording and inspection system as claimed in claim 5, further comprising a map information unit electrically connected to the processing unit;

the map information unit including map information, and the processing unit marking the event signals, the position signals and/or the image signals on the map information.

7. The intelligent driving recording and inspection system as claimed in claim 6, wherein the event signals, the position signals and/or the image signals are marked on the map information as tagged points.

8. The intelligent driving recording and inspection system as claimed in claim 7, wherein the tagged points are shown in different shapes and/or colors to indicate different events sensed by a lane departure warning system, a forward collision warning system, a G-sensor and/or any inside-car driving data.

9. The intelligent driving recording and inspection system as claimed in claim 8, further comprising a inspection unit electrically connected to the memory unit for a user to inspect the image signals, the event signals and/or the position signals corresponding to each of the tagged points.

10. The intelligent driving recording and inspection system as claimed in claim 9, wherein the inspection unit allows a user to review the image signals and the event signals that are captured or generated closely before and after each of the tagged points.

11. The intelligent driving recording and inspection system as claimed in claim 1, further comprising a communication unit being electrically connected to the processing unit for transmitting the event signals and the image signals to an external server.

12. The intelligent driving recording and inspection system as claimed in claim 1, wherein the memory unit includes a plurality of time memory blocks, in each of which the image signals and/or the event signals are stored;

and any of the time memory blocks that stores the image signals marked with event signals is set to be read-only.

13. The intelligent driving recording and inspection system as claimed in claim 12, wherein any other time memory blocks immediately preceding and following each of the read-only time memory blocks are also set by the memory unit to be read-only.

14. The intelligent driving recording and inspection system as claimed in claim 12, wherein any other time memory blocks following each of the read-only time memory blocks and corresponding to a preset length of recording time are also set by the memory unit to be read-only.

15. The intelligent driving recording and inspection system as claimed in claim 12, wherein any other time memory blocks preceding each of the read-only time memory blocks and corresponding to a preset recording time are also set by the memory unit to be read-only.
