Abstract:
Method for controlling a vehicle to maintain a desired position on a roadway includes monitoring roadway information behind the vehicle using a rearward detection device and monitoring vehicle sensor information. Frontward positional information is projected based on rearward positional information obtained from the monitored roadway information behind the vehicle. Forward roadway curvature is estimated based on the vehicle sensor information. Roadway information ahead of the vehicle is modeled based on the projected frontward positional information and the estimated forward roadway curvature to determine desired vehicle positional information. Future vehicle positional information is predicted with respect to the modeled roadway information based on the monitored vehicle sensor information and the estimated forward roadway curvature. The desired vehicle position information is compared to the predicted future vehicle positional information and a steering command is generated based on a deviation in the predicted future position information from the desired vehicle positional information.
