1. An adaptive cruise control system for a vehicle, said adaptive cruise control system comprising:
- a camera having a field of view forward of a vehicle equipped with said adaptive cruise control system, said camera operable to capture image data;
a traffic situation classifier, wherein said traffic situation classifier, responsive to captured image data, determines a traffic condition ahead of the equipped vehicle; and
a control, wherein said control is operable to process captured image data and, at least in part responsive to said traffic situation classifier, generate an output to accelerate or decelerate the equipped vehicle to establish a desired or appropriate velocity of the equipped vehicle based on the determined traffic condition and image data processing.

Abstract
An adaptive cruise control system for a vehicle includes a camera having a field of view forward of a vehicle and operable to capture image data. A traffic situation classifier, responsive to captured image data, determines a traffic condition ahead of the vehicle. A control is operable to process captured image data and, at least in part responsive to the traffic situation classifier, generate an output to accelerate or decelerate the vehicle to establish a desired or appropriate velocity of the vehicle based on the determined traffic condition and image data processing.

10. An adaptive cruise control system for a vehicle, said adaptive cruise control system comprising:
-
a camera having a field of view forward of a vehicle equipped with said adaptive cruise control system, said camera operable to capture image data; a traffic situation classifier, wherein said traffic situation classifier, responsive to captured image data, determines a traffic condition ahead of the equipped vehicle; wherein said traffic situation classifier is responsive to at least one of (i) information about a target vehicle that the equipped vehicle is following, (ii) information about at least one adjacent vehicle that the equipped vehicle is behind but in a different lane than the lane in which the equipped vehicle is traveling, and (iii) road Information pertaining to the road on which the subject vehicle is traveling; a control, wherein said control is operable to process captured image data and, at least in part responsive to said traffic situation classifier, generate an output to accelerate or decelerate the equipped vehicle to establish a desired or appropriate velocity of the equipped vehicle based on the determined traffic condition and image data processing; and wherein said output of said control comprises one of a positive acceleration signal and a negative acceleration signal. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. An adaptive cruise control system for a vehicle, said adaptive cruise control system comprising:
-
a camera having a field of view forward of a vehicle equipped with said adaptive cruise control system, said camera operable to capture image data; a traffic situation classifier, wherein said traffic situation classifier, responsive to captured image data, determines a traffic condition ahead of the equipped vehicle; wherein said traffic situation classifier is responsive to at least one of (i) information about another vehicle that the equipped vehicle is following, (ii) information about at least one other vehicle that the equipped vehicle is behind but in a different lane than the lane in which the equipped vehicle is traveling, and (iii) road Information pertaining to the road on which the subject vehicle is traveling, (iv) information pertaining to a turn signal of another vehicle, (v) information pertaining to a brake light of another vehicle, (vi) information pertaining to another vehicle'"'"'s position in the same lane in which the equipped vehicle is traveling, and (vii) information pertaining to a lateral velocity of another vehicle; a control, wherein said control is operable to process captured image data and, at least in part responsive to said traffic situation classifier, generate an output to accelerate or decelerate the equipped vehicle to establish a desired or appropriate velocity of the equipped vehicle based on the determined traffic condition and image data processing; and wherein said control is responsive to at least one of (i) a determined distance to another vehicle ahead of the equipped vehicle and (ii) a determined relative velocity of another vehicle ahead of the equipped vehicle, as determined from processing of captured image data. - View Dependent Claims (18, 19, 20)
