Vehicles and related systems and methods are provided for mitigating lane departures, alternatively referred to as lane keeping assistance. One method of assisting vehicle operation involves determining a control trajectory for the vehicle over a prediction horizon that satisfies one or more steering angle constraints for operating a steering system of the vehicle based at least in part on a current steering angle, a first difference between the control trajectory and a reference lateral trajectory for the vehicle and a second difference between the control trajectory and a lane boundary, for example, by minimizing a weighted sum of the differences. The method continues by determining a steering angle command for the vehicle based at least in part on the control trajectory and autonomously operating one or more actuators onboard the vehicle in accordance with the steering angle command prior to the vehicle crossing the lane boundary.

Systems and methods are provided for managing transitions between operational modes of a vehicle. The system includes a controller configured to, by a processor: automatically transition between vehicular operational modes without initiation by the driver including a hands-off autonomous driving mode in which the processor controls lateral steering of the vehicle, a hands-on driving assistance mode in which the processor controls the lateral steering of the vehicle while the driver is holding the steering wheel, and a no control mode in which the driver controls the lateral steering of the vehicle. The transition between the operational modes is based on sensed data. The hands-off autonomous driving mode is prioritized over the hands-on driving assistance mode which is prioritized over the no control mode. The controller is further configured to display on a human-machine-interface a notification indicating that at least one of the operational modes is active or not available.
