Object detection in adaptive cruise control
First Claim
1. A method of adaptively controlling the speed of an automotive vehicle having a controller comprising:
- detecting an object and generating an object profile;
generating a navigation signal via a navigation system;
predicting a non-planned future pat of the automotive vehicle in response to said navigation signal;
generating a predicted future path profile via the controller in response to said non-planned future path and said object profile; and
inhibiting a resume speed of the automotive vehicle by preventing acceleration of the automotive vehicle in response to said predicted future path profile and a command originated and generated by the controller.

Abstract
A control system 20 for an automotive vehicle 22, such as an adaptive cruise control (ACC) system, is provided including a controller 24. The controller 24 is electrically coupled to a radar system and a navigation system. The detection system 28 detects an object and generates an object profile. The navigation system 34 generates a navigation signal. The controller 24 in response to the object profile and the navigation signal, generates a predicted future path profile and inhibits resume speed of the vehicle 22 in response to the predicted future path profile. An additional feature of the invention is that the controller 24 may also be electrically coupled to a yaw rate sensor 30. The yaw rate sensor 30 senses the yaw rate of the vehicle 22 and generates a yaw rate signal. The controller 24 in response to the yaw rate signal inhibits resume speed of the vehicle 22.
