Abstract
The current vehicle position is detected by a position and orientation sensor 101. Past accident data related to roads ahead of the detected position are extracted from an accident data storing unit 109. The vehicle driving conditions (e.g. right/left turn, speed, etc.) are detected by a right/left turn sensor 105 and a speed sensor 102. The possibility of occurrence of an accident similar to the extracted past accident is discriminated on the basis of the detected vehicle driving conditions. An accident alarm is generated through a speech outputting unit 107, for example, if an accident occurrence possibility exists.
