Abstract: A method for lane centering control of a host vehicle that is towing a trailer includes: determining in real time, by a controller of the host vehicle, a radius of curvature of a turn, wherein the host vehicle is approaching the turn; determining, by the controller, a trailer required offset based on the radius of the curvature of the turn to maintain the host vehicle and the trailer in a lane while the host vehicle and the trailer move along the turn; and controlling the host vehicle using the trailer offset to maintain the host vehicle and the trailer in a lane while the host vehicle and the trailer move along the turn. The method also allows the host vehicle to avoid encroaching vehicles.

Abstract: An autonomous vehicle and a system and method of operating the autonomous vehicle. The system includes a sensor and a processor. The processor determines an effective observation area of the sensor, the effective observation area being affected by an extrinsic condition. The processor determines an available time for performing a lane change based on the effective observation area and performs the lane change based on the available time.

Abstract: A method for controlling operation of a motor vehicle includes an electronic controller receiving, e.g., from a vehicle-mounted sensor array, sensor data with dynamics information for a target vehicle and, using the received sensor data, predicting a lane assignment for the target vehicle on a road segment proximate the host vehicle. The electronic controller also receives map data with roadway information for the road segment; the controller fuses the sensor and map data to construct a polynomial overlay for a host lane of the road segment across which travels the host vehicle. A piecewise linearized road map of the host lane is constructed and combined with the predicted lane assignment and polynomial overlay to calculate a lane assignment for the target vehicle. The controller then transmits one or more command signals to a resident vehicle system to execute one or more control operations using the target vehicle's calculated lane assignment.

Abstract: A system and method of detecting and mitigating an erratic vehicle by a host vehicle. The method includes gathering sensor information on a calibratable external region surrounding the host vehicle; analyzing the sensor information to detect a target vehicle traveling in a lane and a movement of the target vehicle in the lane; determining whether the movement of the target vehicle in the lane is erratic; if erratic then designating target vehicle as erratic vehicle; assigning a risk score to the erratic vehicle; and implementing a predetermined mitigating action correlating to the assigned risk score to the erratic vehicle. The mitigating action includes one or more of: warning an operator of the host vehicle, warning a vehicle proximal to the host vehicle, and taking at least partial control of the host vehicle to further distance the host vehicle apart from the erratic vehicle.

Abstract: A method to establish a lane-change maneuver, the method includes the steps of calculating a plurality of anchor points along a projected vehicle route and, based on the plurality of anchor points, generating a lane-change maneuver trajectory. The plurality of anchor points can include: a first anchor point based on time, a second anchor point where the vehicle would cross a lane boundary from a host lane to a target lane, and a third anchor point where counter steering torque would be applied to center the vehicle in the target lane.

Abstract: Systems and methods are provided for tracking objects in an autonomous vehicle having multiple sensors. A method includes: determining, by a processor, a type of an environmental condition associated with the autonomous vehicle; adjusting, by the processor, a weight associated with a first type of sensor of the multiple sensors in response to the type of the environmental condition; fusing, by the processor, sensor data from the multiple sensors based on the adjusted weight; tracking, by the processor, an object in the environment of the autonomous vehicle based on the fused sensor data; and controlling, by the processor, the autonomous vehicle based on the tracked object.

Abstract: A method of providing a collision warning within a vehicle comprises detecting an object and determining the distance to the object, identifying when a driver is distracted and measuring the time that the driver has been distracted, calculating an actual time to collision, modifying first and second pre-determined time to collision thresholds based on information from the driver monitoring system and creating first and second modified time to collision thresholds, comparing the actual time to collision to the first and second modified time to collision thresholds, sending a signal to a driver interface to provide an initial warning to the driver when the actual time to collision is less than the first modified time to collision threshold, and sending a signal to the driver interface to provide an imminent collision warning to the driver when the actual time to collision is less than the second modified time to collision threshold.
