A system for controlling lateral positioning in a host vehicle includes a controller having a processor and tangible, non-transitory memory. The host vehicle is located on a host lane defined by a host lane center. The controller is adapted to determine if a first and second enabling condition are met. The first enabling condition is met when the host vehicle is travelling on a non-divided road having no physical barrier separating respective traffic lanes travelling in opposing directions. The second enabling condition is met when the host lane is an inner most lane adjacent to an opposing traffic lane. When the first and second enabling conditions are both met, the controller is adapted to determine a non-divided road offset relative to the host lane center in real-time. Operation of the vehicle is controlled based in part on a magnitude, and a direction of the non-divided road offset.

Vehicle lateral positioning on a non-divided road

A system for controlling lateral positioning in a host vehicle. The system includes a controller adapted to identify targets surrounding a planned path with at least one distance sensor on the host vehicle and determine at least one attribute for each of the targets. The controller is also adapted to determine a lane quality along the planned path with at least one optical sensor on the host vehicle and determine a first target point and a second target point based at least one on the attributes of the targets when the lane quality has degraded below a predetermined threshold. Furthermore, the controller is adapted to calculate a follow trajectory for the host vehicle based on the first and second target points 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.

System and method for positioning a vehicle in a lane

Methods and systems are provided for controlling a vehicle. In one embodiment, a method includes: determining, by a processor, that a lane centering feature is active in the vehicle; identifying, by the processor, a pattern of steering wheel torque; determining, by the processor, a driver requested offset based on a location of the vehicle and a location of a center of the lane; applying, by the processor, the driver requested offset to a planned trajectory of the vehicle; evaluating, by the processor, one or more duration conditions; and in response to the evaluating, selectively generating, by the processor, a control signal based on the planned trajectory with the driver requested offset.
