Description

[0001] The present invention relates to a file management system mounted on a vehicle recording apparatus, and a file management method for reproducing a file in the file management system.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle recording apparatus, and more particularly, to a file management system and a file playback method in a file management system mounted in a vehicle recording apparatus that stores and reproduces automobile driving information and image information.

Recently produced vehicles are equipped with sensors for various measurement and control such as temperature sensor, pressure sensor, acceleration sensor, etc., and these sensors are controlled by an ECU. The ECU was originally intended to precisely control the engine's core functions such as ignition timing of the engine, fuel injection, variable valve timing, idling, and threshold setting. However, with the development of automobile and computer performance, automatic transmission control, drive system, steering system All parts of the car can be controlled.

Automobile recording devices (black box, black box) record information about the driving condition of the vehicle and the accident situation. In the event of a car accident, it is possible to more precisely judge the condition of the car accident based on the record saved in the car recorder. The car recorder is released as a separate terminal with built-in camera and microphone. It is installed in a car, or mounted on a room mirror inside a car, and stores a video shot by its own camera. Depending on the product, You can record both inside and inside. The camera includes a front camera, a rear camera, a left camera, and a right camera, and the vehicle recording apparatus can simultaneously record or reproduce images photographed from each camera.

Korean Patent Registration No. 10-0581744 (hereinafter referred to as 'Prior Art Document 1') discloses a storage device and a storage method in which a plurality of memories capable of storing images are stored, and each memory can be sequentially and repeatedly stored . In the prior art document 1, at the same time that the car is started, the last used memory is retrieved from the CPU to designate the first memory (MC1), the second memory (MC2) as the active state, and the third memory (MC3) as the disabled state When there is a signal of a shock sensor due to a minor accident, it stops the video recording of the memory 1 (MC1) and immediately stores the moving image in the memory 2 (MC2). At the same time, the memory 3 In the activated state, memory 1 (MC1) is deactivated.

In the prior art document 1, since the image device is stopped to store the stored image data after an accident, it is troublesome to set the image storage device by receiving the A / S for re-operation of the image storage device even when a minor accident occurs To solve the problem.

However, according to the prior art document 1, it is inefficient to control the plurality of memories only by the external impact detection signal without considering the difference in the processing speed between the vehicle driving information and the image information in the driving mode and the pseudo-mode . For example, the driving mode of the vehicle, the steering system, and the signal processing speed in the ECU are required to be larger than the driving mode in the differential mode. The size and the processing speed of the image captured by the camera should also be much larger than the mode of driving mode.
