Abstract: A method and apparatus that adjust a field of view of a sensor are provided. The method includes detecting at least one target object in an effective field of view of the sensor, determining an area corresponding to the effective field of view of the sensor, determining whether a critical zone is within the effective field of view based on the determined area of the effective field of view, parameters corresponding to the at least one target object, and parameters corresponding to the host vehicle, and moving the host vehicle within its lane of travel to adjust the effective field of view to capture the critical zone in response to determining that the critical zone is not within the effective field of view.

Abstract: The present application relates to a method and apparatus for real time lateral control and steering actuation assessment for a motor vehicle by determining a desired host vehicle path, establishing a control point along the host vehicle path, generating a motion path between a host vehicle location and the control point, estimating a theoretical acceleration of the host vehicle along the motion path, controlling the host vehicle along the motion path, receiving a measured acceleration from an inertial measurement unit within the host vehicle, generating an error term in response to a comparison of the motion path and the measured lateral travel, and adjusting the performance limits of the sub-features in response to the error term.

Abstract: A vehicle, system and method for operating the vehicle is disclose. The system includes a radar system and a processor. The radar system locates a gap between targets in a second lane adjoining a first lane, with the host vehicle residing in the first lane. The processor is configured to determine a viability value of the gap for a lane change, select the gap based on the viability value, align the host vehicle with the selected gap, and merge the host vehicle from the first lane into the selected gap in the second lane.

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: A powertrain optimization method is used to identify the optimal torque operating range. The method for controlling the vehicle includes: receiving, by a planning controller, a trip plan based on an input from a vehicle-operator, wherein the trip plan is indicative of a planned trip; determining, by the planning controller, a current location of the vehicle using a Global Navigation Satellite System (GNSS) of the vehicle; determining, by the planning controller, a geography of the planned trip using map data from a map database; determining, by the planning controller, a target speed profile for the vehicle as a function of the trip plan, the geography of the planned trip, and a predetermined, optimal acceleration range; determining, by an adaptive cruise controller, a torque request as a function of the target speed profile, a predetermined-optimal torque range, and a current speed of the vehicle.

Abstract: An automotive vehicle includes at least one actuator configured to control vehicle steering, shifting, acceleration, or braking, at least one sensor configured to provide signals indicative of a location and velocity of an object external to the vehicle relative to the vehicle, and at least one controller in communication with the at least one actuator and the at least one sensor. The at least one controller is configured to, in response to a signal from the at least one sensor indicating that a relative velocity between a rearward object and the vehicle exceeds a first threshold and a distance between the rearward object and the vehicle falls below a second threshold, automatically control the at least one actuator to maneuver the vehicle from a first lateral position with respect to a current driving lane to a second lateral position with respect to the current driving lane.
