ABSTRACT:
Alarm apparatus for a motor vehicle includes sensor (101) for detecting an object distance (Do) rearward of the vehicle, means (103) for detecting a vehicle speed (V), means (104) for detecting a traveling direction sideward of the vehicle, a control means (102) for generating an alarm signal (E) on the basis of object distance (Do), vehicle speed (V) and traveling direction (P), alarm (105) driven in response to the alarm signal (E), means (102a) for measuring a time lapse (T) since detection of the traveling direction (P), and means (102b) for setting an alarm distance serving as a comparison reference for the object distance (Do). The alarm (105) is driven when vehicle speed (V) lies within a predetermined range with the time lapse (T) falling within a predetermined time (T1) and when object distance (Do) laterally rearward of the vehicle lies within the alarm distance.
