Abstract: A method for an autonomous vehicle to perform an autonomous parking maneuver is provided. The method includes operating the autonomous vehicle to a destination and then operating the autonomous vehicle to a first parking location at the destination utilizing stored first coordinates of the first parking location. Next the autonomous vehicle determines whether the first parking location is available and performs the autonomous parking maneuver at the first location when the first parking location is available.

Abstract: A method of arbitrating conflicting outputs in a redundant control system. Execution data of a task executed by each controller in the redundant control system is recorded. The execution data includes an initial timestamp of each execution stream, identification of critical functions in each execution stream, and parameter values used by the critical functions. A path executed by each controller is identified based only on the critical functions executed for each execution stream. The recorded execution data of each executed path is applied to an arbitration module. An output result from one of the respective controllers selecting, by an arbitration module, based on the recorded execution data of each executed path. The output result of the selected controller is communicated to a next module for further processing.

Abstract: A front impact mitigation system for a host vehicle and a method for operating a front impact mitigation system. The front impact mitigation system can take into account the position of a rear object that trails the host vehicle to develop a modified front impact mitigation control signal that at least partially mitigates the likelihood of certain rear impact collisions between the rear object and the host vehicle when the host vehicle is responding to the presence of an impending leading obstacle. A modified front impact mitigation control signal may be developed to account for the speed of the host vehicle and the distance that the rear object trails the host vehicle.

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: Systems, Methods and Apparatuses are provided to control actuation of an autonomous operating mode feature of a vehicle to operate when the vehicle is on a limited access freeway. The elevated freeway detection system includes: receiving, by an evaluation module, a plurality of data in real-time about the vehicle including: mapping, GPS and radar data of the vehicle to provide at least a current vehicle location and image data to capture surroundings of the vehicle; determining, whether the vehicle is mapped on a limited access freeway by computing a matching probability location data of the vehicle to the limited access roadway based on the map data, radar data and GPS data; and sending a signal to inhibit the autonomous feature from engaging in the vehicle when the vehicle is not on the limited access freeway.

Abstract: Operation of a vehicle that includes an autonomous operating system including an on-board map database includes operating in a travel lane employing a lane keeping control system and an adaptive cruise control system and monitoring a plurality of lane reference markers. Periodically, parameters are determined, including a first lateral offset for the vehicle based upon a forward-monitoring sensor and one of the lane reference markers, and a second lateral offset for the vehicle based upon a GPS sensor and the map database. A difference and an associated variance are determined, and an error in the map database is determined when the variance is greater than a threshold variance. The vehicle operator is alerted to actively control the vehicle based upon the detected error in the map database.
