detecting an object and generating an object profile; detecting a future path of the automotive vehicle; generating a predicted future path profile in response to said future path and said object profile; and inhibiting a resume speed of the automotive vehicle in response to said predicted future path profile.
- 2. A method as in claim 1 further comprising continuously updating said predicted future path profile.
- 3. A method as in claim 2 wherein updating said predicted future path profile includes updating parameters selected from the following group comprising: object profile, yaw rate, street category, and upcoming future road paths.
- 4. A method as in claim 1 further comprising:
determining that said object is a stopped object; adjusting automotive vehicle speed in relation to said stopped object; and maintaining a safe operating distance between the automotive vehicle and said stopped object.
- 5. A method as in claim 1 further comprising assuming a future road condition selected from the following group comprising: road curvature, speed category, number of lanes, and road inclination is the same as a present road condition.
- 6. A method as in claim 1 wherein detecting the future path of the automotive vehicle comprises:
sensing yaw rate of the automotive vehicle and generating a yaw rate signal; relating said yaw rate to road curvature; and inhibiting resume speed of the automotive vehicle in response to said yaw rate signal.
- 7. A method as in claim 1 wherein detecting the future path of the automotive vehicle comprises using a navigation system to generate a navigation signal including information selected from the following group comprising: automotive vehicle position, speed category, future path of the automotive vehicle, landmark location, road curvature, overhead object location, bridge location, construction zone, number of lanes, road type, and road inclination.
- 8. A method as in claim 1 wherein generating an object profile comprises storing object parameters selected from the following list comprising: relative distance from the automotive vehicle, object location relative to a road, and velocity of said object relative to the automotive vehicle velocity.
- 9. A method as in claim 1 wherein generating a predicted future path profile further comprises determining object location with respect to the future path of the automotive vehicle.
- 10. A method as in claim 1 wherein inhibiting the resume speed of the automotive vehicle further comprises inhibiting resume speed of the automotive vehicle while a present parameter selected from the following group comprising: road curvature, speed category, number of lanes, and road inclination remains constant.
- 11. A method of adaptively controlling the speed of an automotive vehicle having a controller comprising:
sensing yaw rate of the automotive vehicle; generating a yaw rate signal; and inhibiting resume speed of the automotive vehicle in response to said yaw rate signal.
- 12. A method as in claim 1further comprising:
detecting an object and generating an object profile; detecting a future path of the automotive vehicle and generating a predicted future path profile; assuming a future road condition to be the same as a present road condition; and inhibiting resume of the automotive vehicle in response to said object profile, said assumption, and said predicted future path profile.
- 13. A method as in claim 11 wherein detecting a future path of the automotive vehicle is in response to a navigation signal.
- 14. A method as in claim 11 further comprising adjusting the automotive vehicle speed in response to said object profile and said predicted future path profile to avoid a stopped object.
- 15. A method as in claim 11 wherein said controller in response to said object profile and said predicted future path profile signals a warning system.
- 16. A control system for an automotive vehicle comprising:
a detection system detecting an object, said detection system generating a object profile; a navigation system generating a navigation signal; and a controller electrically coupled to said radar system and said navigation system, said controller in response to said object profile and said navigation signal, generating a predicted future path profile and inhibiting resume speed of the automotive vehicle in response to said predicted future path profile.
- 17. A system as in claim 16 wherein said controller in generating a predicted future path profile determines an object location with respect to the future path of the automotive vehicle.
- 18. A system as in claim 16 wherein said controller determines said object to be a stopped object and adjusts the speed of the automotive vehicle in relation to said stopped object.
- 19. A control system for an automotive vehicle comprising:
a yaw rate sensor sensing yaw rate of the automotive vehicle, said yaw rate sensor generating a yaw rate signal; and a controller electrically coupled to said yaw rate sensor, said controller inhibiting resume speed of the automotive vehicle in response to said yaw rate signal.
- 20. A system as in claim 19 further comprising:
a radar system detecting an object, said radar system generating an object profile; and a navigation system generating a navigation signal; said controller electrically coupled to said radar system and said navigation system, said controller in response to said object profile and said navigation signal generating a predicted future path profile and inhibiting resume speed of the automotive vehicle in response to said predicted future path profile.
