PROBLEM TO BE SOLVED: To give an alarm at proper timing in an intersection.SOLUTION: An alarm device 100 includes an own vehicle information acquisition part 8a for acquiring own vehicle information, a mobile object information acquisition part 8b for acquiring mobile object information, a crossing determination part 8c for determining whether respective advance courses of the own vehicle V and the mobile object cross, a distance calculation part 8d for calculating a crossing position distance when determined that they cross, an arrival time calculation part 8e for calculating ECT, a vehicle speed determination part 8f for determining whether the vehicle speed of the own vehicle V is equal to or less than a prescribed speed, a threshold setting part 8g for setting a threshold, and an alarm part 6 for giving an alarm when the ECT is smaller than the threshold. The threshold setting part 8g makes the threshold larger than a threshold when the crossing position distance is less than a preset regulated distance in the case that the crossing position distance is equal to or more than the regulated distance, and makes the threshold larger than a threshold when the speed of the own vehicle V is not determined to be equal to or less than a prescribed speed in the case that the speed of the own vehicle V is determined to be equal to or less than the prescribed speed.SELECTED DRAWING: Figure 1 |
