PURPOSE: A vehicle is provided to utilize data lost by damage of a first storage when collision of the vehicle as backup data stored in a second storage. CONSTITUTION: A vehicle comprises an ACU(Airbag Control Unit) and a second storage. The ACU includes a data generating unit and a first storage. The data generating unit generates self-diagnosis real time data and collision recording data when an accident occurs. The first storage stores the self-diagnosis real time data and the collision recording. The second storage backup-saves the self-diagnosis data from the ACU every 2 hours in a FIFO(First In First Out) method and backup-saves the collision recording data after a first period passes when an ignition switch is on . |
