Cut-in management for an adaptive cruise control system
First Claim
1. A method of managing deceleration of a succeeding vehicle having an adaptive cruise control system adapted for active deceleration of the succeeding vehicle in accordance with a predetermined deceleration function characterized by inverse responsiveness to inter-vehicle spacing between the succeeding vehicle and preceding vehicles in the path of the succeeding vehicle, the method comprising;
- discerning the introduction of a new preceding vehicle into the path of the succeeding vehicle;
determining a new inter-vehicle spacing subsequent to the introduction of the new preceding vehicle; and
, attenuating the inverse responsiveness of the deceleration function when the new inter-vehicle spacing does not exceed a predetermined inter-vehicle spacing.

Abstract
A vehicle having an adaptive cruise control system with active deceleration control responds to capture of new in-path vehicles which violate a predetermined inter-vehicle spacing to attenuate unnecessarily aggressive deceleration responses. New in-path vehicles may be identified by inordinate changes in inter-vehicle spacing. Deceleration response of the system to controlled vehicle closing rate and new in-path vehicle deceleration preferably remain unattenuated.

4. A method of managing deceleration of a succeeding vehicle having an adaptive cruise control system adapted for active deceleration of the succeeding vehicle in accordance with a predetermined deceleration function characterized by inverse responsiveness to inter-vehicle spacing between the succeeding vehicle and preceding vehicles in the path of succeeding vehicle travel, the method comprising:
-
monitoring inter-vehicle spacing between the succeeding vehicle and preceding vehicles;
determining introduction of new preceding vehicles from inordinate changes in inter-vehicle spacing;
when inter-vehicle spacing between the succeeding vehicle and new preceding vehicles is less than a predetermined spacing, attenuating the inverse responsiveness of the predetermined deceleration function during a predetermined interval following introduction of new preceding vehicles. - View Dependent Claims (5)

6. A method of managing deceleration of a succeeding vehicle having an adaptive cruise control system adapted for active deceleration of the succeeding vehicle in accordance with a predetermined deceleration function characterized by inverse responsiveness to inter-vehicle spacing between the succeeding vehicle and preceding vehicles in the path of succeeding vehicle travel, the method comprising:
-
monitoring inter-vehicle spacing between the succeeding vehicle and preceding vehicles;
determining introduction of new preceding vehicles from inordinate changes in inter-vehicle spacing;
when inter-vehicle spacing between the succeeding vehicle and new preceding vehicles is less than a predetermined spacing, attenuating the inverse responsiveness of the predetermined deceleration function during a predetermined interval following introduction of new preceding vehicles wherein the inverse responsiveness of the function to inter-vehicle spacing is attenuated as a function of a predetermined desired minimum inter-vehicle spacing. - View Dependent Claims (7)

8. A method of managing deceleration of a succeeding vehicle having an adaptive cruise control system adapted for active deceleration of the succeeding vehicle in accordance with a predetermined deceleration function characterized by inverse responsiveness to inter-vehicle spacing between the succeeding vehicle and preceding vehicles in the path of succeeding vehicle travel, the method comprising:
-
monitoring inter-vehicle spacing between the succeeding vehicle and preceding vehicles;
determining introduction of new preceding vehicles from inordinate changes in inter-vehicle spacing;
when inter-vehicle spacing between the succeeding vehicle and new preceding vehicles is less than a predetermined spacing, attenuating the inverse responsiveness of the predetermined deceleration function during a predetermined interval following introduction of new preceding vehicles wherein the predetermined deceleration function is further responsive to at least one of (a) time rate of change of inter-vehicle spacing and (b) deceleration of the preceding vehicle.

9. A method of managing deceleration of a succeeding vehicle having an adaptive cruise control system adapted for active deceleration of the succeeding vehicle in accordance with a predetermined deceleration function characterized by inverse responsiveness to inter-vehicle spacing between the succeeding vehicle and preceding vehicles in the path of succeeding vehicle travel, the method comprising:
-
detecting the presence of a preceding vehicle;
determining inter-vehicle spacing;
determining whether the preceding vehicle was recently acquired as a function of a time rate of change of inter-vehicle spacing; and
,attenuating the inverse responsiveness of the deceleration function during a predetermined interval following acquisition of recently acquired preceding vehicles as a function of inter-vehicle spacing. - View Dependent Claims (10)
