    Abstract: Vehicles and related systems and methods are provided for controlling a vehicle in an autonomous operating mode. One method involves identifying one or more avoidance zones in a vicinity of the vehicle, determining a deadline for completing a lateral maneuver to avoid a priority avoidance zone of the one or more avoidance zones, obtaining an initial reference lateral trajectory for the lateral maneuver based at least in part on the deadline, autonomously operating one or more actuators onboard the vehicle in accordance with the initial reference lateral trajectory, and thereafter obtaining one or more updated reference lateral trajectories for the vehicle, wherein the one or more actuators onboard the vehicle are autonomously operated in accordance with the one or more updated reference lateral trajectories in lieu of the initial reference lateral trajectory.

    Abstract: A method of rationalizing a plurality of temperature sensors associated with a plurality of electrical systems of a vehicle includes: maintaining each of the respective electrical systems of the vehicle in a non-operational state for a predetermined period of time; receiving a temperature reading from each of the plurality of temperature sensors following the predetermined period of time; computing a master-reference temperature value from the plurality of received temperature readings; determining a difference between each of the respectively received temperature readings and the computed master-reference temperature value; comparing each determined difference to a threshold; and providing an indicator if one or more of the determined differences exceeds the threshold.

    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 detecting unclassified hazards for a driver assistance system of a vehicle. The systems include a data storage device comprising map data, one or more sensors configured to generate sensor data indicative of one or more sensed objects in proximity to the vehicle, and a controller configured to, by one or more processors thereof, receive the map data and the sensor data, filter the sensor data to omit at least one of the sensed objects located outside of a bounding area that includes a portion of an adjacent lane next to a current lane in which the vehicle is operating, determine whether an unclassified hazard is present in the adjacent lane, and maintain operation of the vehicle in the current lane in response to a determination that the unclassified hazard is present in the adjacent lane.
