Abstract

There is provided a vehicle information recording apparatus capable of making a user easily recognize vehicle information which is recorded in the presence of electric power supply from a backup power source. When a vehicle is involved in an accident and the impact caused by the accident has triggered the interruption of electric power supply from a vehicle power source section and thereupon electrical power is supplied from a backup power source section, predetermined identification information “−A” is added to a folder name of a vehicle power source folder where still image information is recorded in the presence of electric power supply from the vehicle power source section, whereby a backup power source folder is created on a CF card as a new folder. Part of still image information stored in a second SD-RAM is recorded in the backup power source folder created on the CF card.

Claims

1. A vehicle information recording apparatus comprising:

a first memory for recording vehicle information concerning a vehicle in a cyclic manner;

a recording control section for effecting control in a manner that the vehicle information recorded in the first memory is recorded in a second memory every time a predetermined condition is fulfilled, the recording control section being supplied with electric power from a main power source section; and

an auxiliary power source section which acts as a backup for electric power supply from the main power source section to the recording control section,

wherein the recording control section effects control in a manner that the vehicle information recorded in the first memory is recorded in the second memory so that it is possible to discriminate whether the recording of the vehicle information is carried out with use of electric power supplied from the main power source section or from the auxiliary power source section.

2. A vehicle information recording apparatus comprising:

a first memory for recording vehicle information concerning a vehicle in a cyclic manner;

a recording control section for effecting control in a manner that the vehicle information recorded in the first memory is recorded in a second memory every time a predetermined condition is fulfilled, the recording control section being supplied with electric power from a main power source section; and

an auxiliary power source section which acts as a backup for electric power supply from the main power source section to the recording control section,

wherein the recording control section effects control in a manner that the vehicle information recorded in the first memory is recorded in the second memory so that it is possible to discriminate that the recording of the vehicle information is carried out with use of electric power supplied from the auxiliary power source section.

3. A vehicle information recording apparatus comprising:

a first memory for recording vehicle information concerning a vehicle in a cyclic manner;

a recording control section for effecting control in a manner that a folder is created on a second memory and the vehicle information recorded in the first memory is recorded in the folder every time a predetermined condition is fulfilled, the recording control section being supplied with electric power from a main power source section; and

an auxiliary power source section which acts as a backup for the electric power supply from the main power source section to the recording control section,

wherein the recording control section effects control in a manner that a new folder is created on the second memory by adding, to a folder name of the folder, identification information whereby it is possible to discriminate that the recording of the vehicle information is carried out with use of electric power supplied from the auxiliary power source section, and part of the vehicle information recorded in the first memory is recorded in the new folder.

4. The vehicle information recording apparatus of claim 3, wherein, in creating the new folder, the recording control section determines a folder name according to a predetermined regulation, and adds the identification information to the tail end of the folder name.

5. A program which allows a computer to function as a recording control section for effecting control in a manner that,

in the presence of electric power supply from a main power source section, a folder is created on a second memory and vehicle information concerning a vehicle recorded in a first memory in a cyclic manner is recorded in the folder every time a predetermined condition is fulfilled, and

upon a switch to electric power supply from an auxiliary power source section which acts as a backup for the electric power supply from the main power source section to the recording control section, a new folder is created on the second memory, in a folder name of the new folder is added predetermined information whereby it is possible to discriminate that the recording is carried out with use of electric power supplied from the auxiliary power source section, and part of the vehicle information recorded in the first memory is recorded in the new folder.

6. A computer-readable recording medium where the program of claim 5 has been recorded.
