Abstract
Abstract A drive assist system of a vehicle for preventing a lane moving-out includes a pair of CCD cameras (3) for taking picture images of the scenery in front of the vehicle, an image processing section (4) for processing the picture images, a road/object detecting section (11) for obtaining image data, a lane moving-out judging section (12) for judging a lane moving-out from a lane, a roadside judging section (13a) for issuing an alarm when it judges a lane moving-out in the roadside direction, a moving-out direction obstacle judging section (13b) for issuing an alarm when there is a possibility of colliding with an obstacle on a moving-out direction lane, a lane width judging section (13c) for stopping or suppressing an alarm in case where the lane moving-out is an avoidable behavior due to the narrow width of the lane and a front direction obstacle judging section (13d) for stopping or suppressing an alarm in case where the lane moving-out is for avoiding an obstacle in front of the vehicle. <IMAGE> <IMAGE>

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
195 words
A drive assist system for raising an alarm when a vehicle moves out
from a first lane on which said vehicle is travelling, comprising: a running environment detecting means for detecting running
conditions of said vehicle, the position of said vehicle, the position of said first lane
and the position of a neighboring lane and for recognizing objects existing on said
first lane and said neighboring lane in relationship to said position of said vehicle; a lane moving-out judging means (12) based on information obtained
from said running environment detecting means for comparing said position of said
vehicle with said position of said first lane and for judging a lane moving-out from
said first lane of said vehicle; a warning signal generation judging means (13) for outputting a signal
to raise an alarm when said vehicle moves out from said first lane and at least when
it is judged based on said information obtained from said running environment
judging means that said neighboring lane does not exist in the direction of moving
out; and a warning control means (14) for operating a warning device based on
said signal from said warning signal generation judging means.
Claim 2
Dependent Claim
211 words
A drive assist system for raising an alarm when a vehicle moves out
from a first lane on which said vehicle is travelling, comprising: a running environment detecting means for detecting running
conditions of said vehicle, the position of said vehicle, the position of said first lane
and the position of a neighboring lane and for recognizing objects existing on said
first lane and said neighboring lane in relationship with said position of said vehicle; a lane moving-out judging means (12) based on information obtained
from said running environment detecting means for comparing said position of said
vehicle with said position of said first lane and for judging a lane moving-out from
said first lane of said vehicle; a warning signal generation judging means (13) for outputting a signal
to raise an alarm when said vehicle moves out from said first lane in the direction of a
neighboring lane to said first lane and at least when it is judged based on said
information obtained from said running environment judging section that an object
exists on said neighboring lane and that said object is an obstacle to said vehicle; and a warning control means (14) for operating an warning device based on
said signal from said warning signal generation judging means.
Claim 3
Dependent Claim
196 words
A drive assist system for raising an alarm when a vehicle moves out
from a first lane on which it is travelling, comprising: a running environment detecting means for detecting running
conditions of said vehicle, the position of said vehicle, the position of said first lane
and the position of a neighboring lane and for recognizing objects existing on said
first lane and said neighboring lane in relationship to said position of said vehicle; a lane moving-out judging means (12) based on information obtained
from said running environment detecting means for comparing said position of said
vehicle with said position of said first lane and for judging a lane moving-out from
said first lane of said vehicle; a warning signal generation judging means (13) for outputting a signal
to stop or suppress an alarm when said vehicle moves out from said first lane and at
least when it is judged based on said information obtained from said running
environment judging means that the width of said first lane is narrower than a
predetermined value; and a warning control means (14) for operating a warning device based on
said signal from said warning signal generation judging means.
Claim 4
Dependent Claim
206 words
A drive assist system for raising an alarm when a vehicle moves out
from a first lane on which said vehicle is travelling, comprising: a running environment detecting means for detecting running
conditions of said vehicle, the position of said vehicle, the position of said first lane
and the position of a neighboring lane and for recognizing objects existing on said
first lane and said neighboring lane in relationship to said position of said vehicle; a lane moving-out judging means (12) based on information obtained
from said running environment detecting means for comparing said position of said
vehicle with said position of said first lane and for judging a lane moving-out from
said first lane of said vehicle; a warning signal generation judging means (13) for outputting a signal
to stop or suppress an alarm when said vehicle moves out from said first lane and at
least when it is judged based on said information obtained from said running
environment judging section that an object exists on said first lane within a pre-established
range and that said object is an obstacle to said vehicle; and a warning control means (14) for operating an warning device based on
said signal from said warning signal generation judging means.
Claim 5
Dependent Claim
45 words
The drive assist system according to claim 4, wherein said pre-established
range in said warning signal generation judging means (13) includes the
width of said first lane and a specified width of a range provided on left and right
sides of said first lane, respectively.
