The open signal generator 12 generates an emergency open signal including a window open signal for lowering the window of the vehicle by a predetermined interval when the shock detector 11 detects an abnormal shock or more. The interval at which the window descends may be set to various values according to the vehicle model and the size of the window glass. The interval may be set such that the window is completely lowered, half lowered, or lowered by a specific interval (for example, 30 cm). It is desirable that at least half of the window be opened, since the car door must be opened through the open gap of the window or the passenger must be evacuated out of the vehicle.

Meanwhile, as described above, the emergency opening signal may further include a door opening signal to unlock the door in addition to the window opening signal.

The delay unit 13 serves to generate a delay open signal by delaying the generated emergency open signal by a predetermined time.
