Vehicle data recorder
First Claim
1. A vehicle data recorder comprising:
- a plurality of vehicle state-detecting sensors for detecting a state of a vehicle at the time of running;
a recording unit for temporarily recording detected values of said plurality of the vehicle state detecting sensors;
a recording/storing unit for recording and storing the detected values of said plurality of the vehicle state detecting sensors;
an airbag body installed inside an interior of the vehicle and configured to mitigate an impact force applied from an exterior of the vehicle;
an airbag body controller configured to inflate the airbag body upon receipt of a trigger signal from outside thereof;
a judging unit configured to judge that an event starts when a detected value of a given one of said plurality of the vehicle state-detecting sensors reaches or exceeds a first threshold value and to judge that the airbag body is to be developed when said given one vehicle state-detecting sensor reaches or exceeds a second threshold value, the first threshold value being lower than the second threshold value; and
a control unit configured for performing (i) an recording operation that the detected values of said vehicle state detection sensors are recorded and taken into the recording unit at a predetermined cycle, (ii) a recording/storing operation that when the judging unit judges that said event starts, the detected values of the vehicle state-detecting sensors recorded in the recording unit are recorded and stored in said recording/storing unit, and (iii) an airbag controlling operation that when the judging unit judges that the airbag is to be developed, the control unit outputs said trigger signal to said airbag body control unit.

Abstract
A vehicle data recorder includes plural vehicle state-detecting sensors for detecting a state of a vehicle at the time of running, a recording unit for temporarily recording detected values of the sensors, a recording/storing unit for recording and storing the detected values of the sensors; an airbag body, an airbag body controller configured to inflate the airbag body, a judging unit to judge that an event starts and to judge that the airbag body is to be developed and a control unit for performing (i) an recording operation that the detected values of said vehicle state detection sensors are recorded and taken into the recording unit at a predetermined cycle, (ii) a recording/storing operation that when the judging unit judges that the event starts, the detected values of the vehicle state-detecting sensors recorded in the recording unit are recorded and stored in said recording/storing unit, and (iii) an airbag controlling operation that when the judging unit judges that the airbag is to be developed, the control unit outputs said trigger signal to said airbag body control unit.
