1. An vehicle alarm device operable at a time of changing lanes comprising:
- an obstacle detecting means for detecting obstacles in a lane where a driver'"'"'s own vehicle runs and lanes adjacent thereto,an obstacle recognizing means for recognizing the obstacles detected by said obstacle detecting means,a lane state recognizing means for recognizing a state of lanes based on the obstacles recognized by said obstacle recognizing means,an alarm determining means for determining whether or not an alarm is necessary using the obstacles recognized by said obstacle recognizing means and the state of lanes recognized by said lane state recognizing means, andan alarm means for alerting said driver based on determination by said alarm determining means.

Abstract
An alarm device for vehicle operable at a time of changing lanes which does not alert in case of congestion by inputting an obstacle by a scan laser radar 1, recognizing the obstacle by a obstacle recognizing means 9 based on thus inputted information, recognizing the congestion by a lane state recognizing means 10 based on thus recognized obstacle and a state of peripheral lane, setting an optimum area for alerting by an alarm determining means 11 based on thus recognized state of lane, and conducting an alarm by an alarm means 7 based on the obstacle within the optimum area for alerting.

21. A vehicle alarm device usable to alert a driver of a vehicle of obstacles in close proximity to the driver'"'"'s vehicle, said vehicle alarm device comprising:
-
an obstacle detector operable to detect obstacles in a lane wherein said driver'"'"'s vehicle is travelling and areas adjacent thereto; an obstacle recognizer operable to determine a type of obstacle for said obstacles detected by said obstacle detector; a lane state recognizer operable to determine a state of the lane wherein said driver'"'"'s vehicle is travelling and lanes adjacent thereto wherein said lane state recognizer uses information provided by said obstacle detector; an alarm determiner operable to determine whether or not an alarm is necessary using information provided by said obstacle recognizer and said lane state recognizer, and an alarm operable to alert said driver of an obstacle when said alarm determiner determines said alarm is necessary. - View Dependent Claims (22, 23)
