Abstract: Acceleration data on acceleration that a vehicle undergoes are written in a readable memory, the acceleration being detected by an acceleration sensor. When an airbag is inflated, the time of the inflation is determined. Either acceleration data on acceleration that the vehicle undergoes during a predetermined time period before or after the determined time or acceleration data on acceleration that the vehicle undergoes during two predetermined time periods before and after the determined time are read from the readable memory, and the acceleration data read from the memory are stored in a nonvolatile memory as a collision history.
