Abstract: Methods and systems of controlling a vehicle. The methods and systems include switching to a second processor executed mode in response to determining that a range of perception information extends to a range end point that is closer to the vehicle than a first Look Ahead (LA) point. In the second processor executed mode: a motion planner requests a lateral controller to provide a closer LA point relative to the vehicle. The lateral controller determines the closer LA point and sends the closer LA point to the motion planner. The lateral controller generates control commands for an EPS system based on an error between a desired trajectory and an actual trajectory at the closer LA point. The motion planner generates the desired trajectory based on perception data and the closer LA point.

Abstract: 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.

Abstract: Methods, systems and a vehicle control system for a vehicle is provided. The vehicle control system includes an Electric Power Steering System (EPS), and a sensor system including a vehicle dynamics sensor configured to provide vehicle dynamics data and a temperature sensor configured to provide measured outside temperature. A processor is in operable communication with the EPS and the sensor system. The processor is configured to execute program instructions. The program instructions are configured to cause the processor to: execute an automated lateral control algorithm based on the vehicle dynamics data to generate a steering command, adapt the automated lateral control algorithm based on the measured outside temperature so that the steering command compensates for changing lateral response of the vehicle as a result of changing environmental temperature; and provide the steering command to the EPS, wherein the EPS is configured to laterally control the vehicle based on the steering command.

Abstract: A vehicle and a system method of operating the vehicle is disclosed. The system includes a monitoring module and a mitigation module operating on a processor. The monitoring module is configured to measure a degradation in an operation parameter of the vehicle, the vehicle operating in a first state based on a first value of a set of adaptive parameters. The mitigation module is configured to determine a threat to the vehicle due to operating the vehicle in the first state with the degradation in the operation parameter and adjust the set of adaptive parameters from the first value to a second value that mitigates the threat to the vehicle, wherein the processor operates the vehicle in a second state based on the second value.

Abstract: Systems and methods for smoothing automated lane change (ALC) operations. A mission planner, upon receipt of an ALC request, sends a ALC heads up signal to a lateral control. The mission planner then begins confidence building operations, for a preprogrammed duration of time, and awaits an ALC ready signal from the lateral control. The lateral control, upon receipt of the ALC heads up, calculates an index of readiness, RALC, as a function of the requested ALC, a current trajectory, and a lane centering control path. When RALC is less than or equal to a readiness threshold, Rt, the lateral control sends the ALC ready signal. When RALC is greater than Rt, the lateral control generates a steering correction and applies the steering correction to reduce the RALC and thereby stabilize the vehicle and send the ALC ready signal. Upon receiving the ALC ready signal, the ALC operation is executed.
