When trigger _{T g} prior to recording time _{T bef} seconds, the time obtained by adding the recording time _{T aft} seconds after the time trigger _{T g} corresponds to the total time of the recording range Rh in one event.

Recording time _{T bef} before when the trigger occurs The _{T g,} can be set in the range of 12 seconds 8 seconds, recording time _{T aft} after when the trigger occurs The _{T g,} set between 12 seconds and not more than 8 seconds Is possible. In other words, the recording range Rh of 1 event trigger occurs when T _g before 8 seconds 12 seconds or less, and is capable of setting a maximum 20 seconds in the range of less than 12 seconds 8 seconds or more after the time trigger T _g .

In this embodiment, the total time of the recording range Rh in one event is set to a maximum of 20 seconds, but the total time of the recording range Rh is not limited to 20 seconds, and the total time of the recording range Rh is For example, it may be set to a maximum of 30 seconds. In this case, a trigger generation time _{T g} prior to recording time _{T bef,} for example set in the range of 5 seconds to 25 seconds or less, the recording time _{T aft} after time trigger _{T g,} for example 25 seconds or more 5 seconds You may set in the following ranges.

The G sensor 15 is a two-axis type that detects the gravitational acceleration in the X-axis direction and the Y-axis direction as described above, and is configured to be able to detect the gravitational acceleration in the front-rear direction and the left-right direction of the vehicle. Therefore, it is possible to reliably detect not only the collision accident in the front-rear direction of the vehicle but also the collision accident in the left-right direction, and analyze the cause. The threshold determination is performed by the vector sum of the gravitational acceleration in the front-rear direction and the gravitational acceleration in the left-right direction. This threshold value can be changed to an arbitrary value by setting.
