Patent ID: 8527136

Claim:
A vehicular action data record apparatus for a vehicle, the apparatus comprising: an action data output section to output action data relevant to an action of the vehicle; a record section to record the action data; an anomaly determination section to determine whether an action of the vehicle is anomalous based on the action data outputted by the action data output section to identify an anomalous action; and a record control section to execute a record process to cause the record section to record action data relevant to an anomalous action of the vehicle when the anomalous action is identified by the anomaly determination section, the record section containing a plurality of archive areas, each of which is enabled to record a single action data set that contains at least one action data relevant to an anomalous action, the plurality of archive areas being enabled to record the action data sets, respectively, in a predetermined recording order relative to the record process, wherein: in cases that an occurrence time interval between adjacent anomalous actions that are identified by the anomaly determination section is within a predetermined time period, the record control section is further configured to cause the record section to record action data sets relevant to the adjacent anomalous actions, which are identified by the anomaly determination section, in different archive areas of the plurality of archive areas according to the recording order, respectively; and in cases that an occurrence time interval between adjacent anomalous actions that are determined by the anomaly determination section exceeds the predetermined time period, the record control section is further configured to cause the record section to record a newer action data set relevant to a newer anomalous action of the adjacent anomalous actions, which are identified by the anomaly determination section, by overwriting an earliest ordered archive area, which is earliest in the recording order among the plurality of archive areas, and to cause other archive areas, which is among the plurality of archive areas and other than the earliest ordered archive area, to erase all past action data sets that are recorded in the other archive areas, respectively.
