    • A method and system may determine, in a vehicle, a desired path around an object based on a location of the object relative to the vehicle, relative speed, road parameters and one or more vehicle parameters. The method and system may calculate one or more vehicle control parameter values which minimize a predicted deviation from the desired vehicle path. The method and system may determine whether the one or more vehicle control parameter values would cause the vehicle to exceed one or more vehicle stability constraints. If the one or more vehicle control parameter values would cause the vehicle to exceed one or more vehicle stability constraints, the one or more vehicle control parameter values may be reduced to one or more vehicle control parameter values not causing the vehicle to exceed the one or more vehicle stability constraints. The method and system may output the one or more vehicle control parameter values to a vehicle automated control device.

    • A system and method for providing steering control for lane changing and lane centering purposes in an autonomous or semi-autonomous vehicle system. A vehicle vision system calculates roadway lane marking information, such as lateral offset, yaw angle and roadway curvature with respect to the vehicle's centered coordinate system. The roadway is then modeled as a second order polynomial equation. The method then predicts roadway lateral position and yaw angle over a pre-defined lane change completion time using a vehicle dynamic model. The method then compares a predicted vehicle path with a desired vehicle path to generate an error value, and calculates a steering angle command to minimize the error value, where the steering angle command is calculated as a function of vehicle lateral position, vehicle lateral speed, vehicle yaw rate and vehicle yaw angle. The steering angle command is then sent to the vehicle steering system.

    • A system for providing path generation for automated lane centering and/or lane changing purposes. The system includes a desired path generation processor that receives signals detecting the roadway on which the vehicle is traveling, a request for a lane change, vehicle state information and a steering angle of the vehicle. The system also includes a path prediction processor that predicts the vehicle path based on vehicle state information including vehicle longitudinal speed, vehicle lateral speed, vehicle yaw-rate and vehicle steering angle. The desired path information and the predicted path information are compared to generate an error signal that is sent to a lane change controller that provides a steering angle signal to turn the vehicle and reduce the error signal. The desired path generation processor can use a fifth order polynomial equation to determine the desired path of the vehicle based on the input signals.
