An alarm system includes a miniature camera (), a loudspeaker (), a vehicle speed sensor (), a longitudinal G sensor (), a lateral G sensor () and an on-vehicle unit (). A CPU () of the on-vehicle unit () executes respective programs ()&#x2013;() in a ROM (), thereby outputting, if a traveling distance during a period for which a driver D continues to take an abnormal behavior exceeds a predetermined value when a traveling state of an automobile is kept stable, an alarm corresponding to a magnitude of the excess over the predetermined value from the loudspeaker (). The alarm system is thus configured and is therefore capable of exactly outputting the alarm when a danger actually rises.

An image sensor section and a millimeter-wave sensor section separately detect objects. A sensor matching section determines whether the objects detected by the image sensor section and the millimeter-wave sensor section are one and the same object. If the objects are one and the same object, the sensor matching section estimates a position of the obstacle after a certain period. A collision prediction section determined whether there is going to be a collision between the vehicle and the objectfrom the position estimated by the sensor matching section.
