Wherein the tachograph 102 is mountable near an interior rear view mirror. As shown in fig. 1b, which is a schematic structural diagram of the automobile data recorder 102, the automobile data recorder 102 includes: a collision detection module 104, a control module 106, a storage module 108, and a recording module 110. The storage module 108 includes a permanent memory and a temporary buffer.
In one embodiment, as shown in fig. 2, a driving record data processing method is provided, which is described by taking the method as an example applied to the driving recorder 102 in fig. 1, and includes the following steps:
step S202, when the recording function of the driving recorder is closed, driving record data obtained by the driving recorder is stored in a temporary buffer area; the recording function is used for storing the driving record data into the permanent memory.
The temporary buffer area can be an annular buffer area and is used for temporarily storing the driving record data recorded by the driving recorder.
The driving record data can comprise driving video data and/or driving audio data.
In a specific implementation, when the control module 106 of the automobile data recorder 102 detects that the recording function of the automobile data recorder 102 is turned off, that is, the automobile data recorded by the automobile data recorder 102 cannot be stored in the persistent memory. At this time, the control module 106 sends a temporary storage instruction to the storage module 108, instructs the storage module 108 to start a temporary storage function, and temporarily stores the driving video data and/or the driving audio data recorded by the driving recorder 102 in a temporary buffer area.
And step S204, when the vehicle accident is detected, extracting the driving record data in the temporary buffer area to obtain the pre-accident record data.
The pre-accident recorded data may represent driving recorded data within a certain time before a node where the vehicle has an accident.
In a specific implementation, when the collision detection module 104 of the automobile data recorder 102 detects an accident, an emergency video storage instruction is sent to the control module 106, the control module 106 is instructed to extract the automobile data in a temporary buffer area within a certain time before the accident occurs, and the obtained automobile data is used as the pre-accident recorded data. In addition, when an accident occurs, the control module 106 will control the car recorder 102 to start the emergency recording function, so as to record the video data and audio data after the accident occurs, and store the video data and audio data in the permanent memory directly.
Step S206, the pre-accident recording data is transferred to a permanent memory.
In a specific implementation, after the control module 106 extracts the driving record data in the temporary buffer area to obtain the pre-accident record data, the pre-accident record data is transferred to the permanent memory for storage. Meanwhile, the permanent memory stores the driving record data recorded by the driving recorder 102 after the accident as the post-accident recording data, so that the driving record data before and after the accident can be obtained.
According to the driving record data processing method, when the recording function of the driving recorder is closed, the driving record data are temporarily stored through the temporary buffer area; when the vehicle accident is detected, the driving record data in the temporary buffer area is extracted and is transferred to the permanent memory.

In a specific implementation, when the collision detection module 104 of the automobile data recorder 102 detects that an accident occurs in a vehicle, an emergency video storage instruction is sent to the control module 106, the driving record data in the temporary buffer area is obtained first, the driving record data is used as initial record data, and then in the initial record data, the driving record data in a set time before the time point when the accident occurs is extracted and used as pre-accident record data.
In practical application, the temporary buffer area may be set in the following manner: the driving record data can be only stored within a set time, for example, the temporary buffer area only buffers 20s of driving record data, and when the temporary buffer area is full, the new driving record data will overwrite the previous driving record data. When the vehicle accident is detected, all the driving records in the temporary buffer area are extracted and used as the recording data before the accident, and the recording data are transferred to the permanent memory.
Another arrangement of the temporary buffer area may be as follows: longer video and audio times, such as 1 hour, may be buffered. When the vehicle accident is detected, the driving record data of the accident node is extracted only within a set time, for example, 20s before the accident occurs, and is stored into the permanent memory as the pre-accident record data.
In this embodiment, when an accident of the vehicle is detected, the driving record data within the set time in the temporary buffer area is extracted as the pre-accident record data. Through the setting of temporary buffer, do not occupy the memory of memory, only when the emergence accident, draw out the driving recording data in a period before the emergence accident and save, realized satisfying the user's demand and can closing when recording the function, when guaranteeing to take place the accident, still can take notes the driving recording data before the emergence accident, thereby, traditional vehicle event data recorder has been solved, when recording the function and being closed, if the emergence accident, the problem of the driving recording data before the unable recording accident.
