Vehicular action data record apparatus
First Claim
1. 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 configuredto 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 configuredto 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, andto 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.

Abstract
When anomalous vehicle actions occur in a vehicle multiple times, it is determined whether each action data is included in a series of action data sets that are closely related mutually or an irrelevant independent action data set. When it is included in the series of action data sets, the ECUs record the series of action data sets in respective own memories according to a predetermined recording order. In contrast, when it is included in the independent action data set, an earliest ECU that is earliest in the recording order records the action data by overwriting its own memory. In this case, the earliest ECU transmits an instruction to other ECUs to delete all past action data that are recorded in own memories of the other ECUs.
