METHOD TO ADAPTIVELY CONTROL VEHICLE OPERATION USING AN AUTONOMIC VEHICLE CONTROL SYSTEM
First Claim
1. Method for operating a vehicle in response to an operator request for a lane change maneuver, the vehicle including a vehicle monitoring system for estimating vehicle motion states, a spatial monitoring system, an adaptive cruise control system for vehicle speed and acceleration control, a steering controller for vehicle lateral motion control, and an autonomic control system, the method comprising:
- generating a preferred travel path responsive to the operator request for a lane change maneuver;
using the autonomic control system to command vehicle operation to achieve the preferred travel path;
determining vehicle motion states;
predicting a travel path associated with the vehicle motion states;
adjusting the commanded vehicle operation to achieve the preferred travel path based upon the predicted travel path;
estimating a roadway using the spatial monitoring system; and
adapting the preferred travel path responsive to the estimated roadway.

Abstract
A vehicle includes a vehicle monitoring system for estimating vehicle motion states, a spatial monitoring system, an adaptive cruise control system for vehicle speed and acceleration control, a steering controller for vehicle lateral motion control, a roadway estimator, and an autonomic control system. Commanded vehicle operation is adjusted to achieve a preferred travel path based upon a predicted travel path and an estimated roadway. The preferred travel path is adapted responsive to the estimated roadway.

14. Method for controlling operation of a vehicle configured to execute an autonomic lane change maneuver, comprising:
-
estimating a roadway; generating a preferred travel path in response to an operator request for a lane change maneuver and the estimated roadway; estimating a first vehicle lateral acceleration state corresponding to the preferred travel path; adapting the preferred travel path when the first vehicle lateral acceleration state exceeds a threshold; determining a second vehicle lateral acceleration state corresponding to the adapted preferred travel path; and reducing vehicle speed when the second vehicle lateral acceleration state exceeds the threshold. - View Dependent Claims (15, 16, 17, 18, 19)
