1. A data recording apparatus for a vehicle comprising:

  • circuitry including;

    an event occurrence determination circuitry that determines whether a predetermined event occurs in a vehicle;

    a data recording control circuitry that, in a case where the event occurrence determination circuitry determines that the predetermined event occurs, records data indicating a vehicle state in a memory 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 circuitry that determines whether the recording based on a previous event is actually being carried out by the data recording control circuitry at a time when it is determined by the event occurrence determination circuitry that the predetermined event occurs, whereinthe data recording control circuitry, in a case where the on-data-recording determination circuitry 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 memory for the predetermined event, andthe data recording control circuitry, in a case where the on-data-recording determination circuitry determines that the recording based on the previous event is not actually being carried out at the time when it is determined that the predetermined event occurs, records the data in the memory at each predetermined time at least until the predetermined period of time elapses from the occurrence of the predetermined event, whereas in a case where the on-data-recording determination circuitry 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, continues to record the data in the memory at each predetermined time at least until a predetermined period of time elapses from an occurrence of the previous event, and also records the data in the memory at the time when it is determined that the predetermined event occurs.
