Abstract
An alarm operation is activated by closing all vehicle doors (S11). When all doors are locked (S12), an active alarm awaiting state is set (S13) and, when all doors are not locked (S12), a passive alarm awaiting state is set (S16). When all the doors are locked after a passive alarm awaiting state was set (S17), the passive alarm awaiting state shifts to an active alarm awaiting state. Then, whether or not all doors are unlocked is judged (S14). If they are unlocked, the alarm awaiting state is released (S15). If the alarm mode is preserved intact, without shifting to be in an active alarm mode, the alarm awaiting state is released (S15) by turning on an ignition or accessory switch within fifteen seconds after a door was opened (S18).
