Abstract

An adaptive cruise controller having dynamics matching as a function of the situation includes an identification device for identifying various predefined categories of single-file driving situations, and for selecting a dynamic profile matched to the situation identified.

Claims

1-6. -6. (canceled)

7. An adaptive cruise controller having dynamics matching as a function of the situation, comprising:

an identification device for identifying various predefined categories of single-file driving situations, and for selecting one dynamic profile matched to the situation identified.

8. The cruise controller according to claim 7, wherein in identifying the categories, the identification device distinguishes whether a host vehicle is on a road without intersections, or on a road section before an intersection or junction.

9. The cruise controller according to claim 7, wherein the identification device includes an interface to a navigation system.

10. The cruise controller according to claim 7, wherein the identification device includes an interface to a traffic-congestion information system.

11. The cruise controller according to claim 7, wherein dynamic profiles differ in a parameter which determines an acceleration behavior of a host vehicle in response to changes in speed of preceding vehicles, or when a traffic lane traveled by the host vehicle becomes free.

12. The cruise controller according to claim 7, wherein dynamic profiles differ in a time gap with which a preceding vehicle is followed within the framework of a distance control.
