1. A system for controlling lateral positioning in a host vehicle, the system comprising:
a controller having a processor and tangible, non-transitory memory on which instructions are recorded, the controller being adapted to:
identify a plurality of targets surrounding a planned path of the host vehicle with at least one distance sensor on the host vehicle;
determine at least one attribute for each of the plurality of targets;
determine a lane quality along the planned path with at least one optical sensor on the host vehicle;
determine a first target point and a second target point based on the at least one attribute for each of the plurality of targets when the lane quality has degraded below a predetermined threshold;
calculate a follow trajectory for the host vehicle based on the first target point and the second target point; and
direct the host vehicle along the follow trajectory when a lane marker identification distance is less than a minimum look ahead distance for the host vehicle.
