Abstract
In order to carry out data recording efficiently, a data recording apparatus for a vehicle in the present invention determines whether a predetermined event occurs in a vehicle. When it is determined that a predetermined event occurs, generally at least data indicating a vehicle state is recorded in a recording part from an occurrence of the predetermined event until a predetermined period of time elapses. Also, it is determined whether, at a time when it is determined that the predetermined event occurs, the recording in the recording part is actually being carried out. When it is determined that the recording is actually being carried out, the data indicating the vehicle state at that time is recorded in the recording part instead of recording the data based on the occurrence of the predetermined event at least from the occurrence of the predetermined event until the predetermined period of time elapses.

10. A data recording apparatus for a vehicle comprising:
-
an event occurrence determination part that determines whether a predetermined event occurs in a vehicle; a data recording control part that, in a case where the event occurrence determination part determines that the predetermined event occurs, records data indicating a vehicle state in a recording part at each predetermined time at least until a predetermined period of time elapses from the occurrence of the predetermined event; and an on-data-recording determination part determines whether the recording based on a previous event is actually being carried out by the data recording control part at a time when it is determined by the event occurrence determination part that the predetermined event occurs, wherein the data recording control part, in a case where the on-data-recording determination part determines that the recording based on the previous event is actually being carried out at the time when it is determined that the predetermined event occurs, carries out recording of only the data at the time in the recording part for the predetermined event. - View Dependent Claims (11)

12. A data recording apparatus for a vehicle comprising:
-
an event occurrence determination part that determines whether a predetermined event occurs in a vehicle; a first data recording control part that, in a case where the event occurrence determination part determines that the predetermined event occurs, records data indicating a vehicle state at each predetermined time in a recording part at least until a predetermined period of time elapses from an occurrence of the predetermined event; an occurrence time recording control part that records in the recording part a time when the predetermined event occurs calculated by using a second timer different from a first timer that counts a time required for generating timing for the recording by the first data recording control part; an on-data-recording determination part determines whether the recording is actually being carried out by the first data recording control part at a time when it is determined by the event occurrence determination part that the predetermined event occurs; and a timer control part that, in a case where the on-data-recording determination part determines that the recording by the first data recording control part is not being carried out at the time, resets and starts the second timer. - View Dependent Claims (13, 14, 16)

15. A data recording apparatus for a vehicle comprising:
-
an event occurrence determination part that determines whether a predetermined event occurs in a vehicle; and a data recording control part that, in a case where the event occurrence determination part determines that the predetermined event occurs, records data indicating a vehicle state at each predetermined time in a recording part at least from a predetermined period of time before an occurrence of the predetermined event until the occurrence of the predetermined event, wherein in the data recording control part, the farther from the time of occurrence of the event a current time is, the longer an interval of the predetermined time is, and the closer to the time of occurrence of the event a current time is, the shorter an interval of the predetermined time is.
