Abstract: A system according to the present disclosure includes an actuator control module and a damping ratio module. The actuator control module is configured to control an actuator of a vehicle to cause the vehicle to perform a yaw maneuver by rotating about its yaw axis. The damping ratio module is configured to determine a damping ratio based on an operating parameter measured during the yaw maneuver. The operating parameter includes at least one of a yaw rate of the vehicle, a yaw rate of a trailer connected to the vehicle, a lateral acceleration of the vehicle, a lateral acceleration of the trailer, a heading angle of the vehicle, and a hitch angle between a longitudinal axis of the vehicle and a longitudinal axis of the trailer.

Abstract: A process for correcting longitudinal roll from an offset load using active roll control within a vehicle is provided. The process includes, within a computerized controller using axle-based control to control a suspension system, operating programming to control pneumatic pressure supplied to each of a plurality of air spring devices within the suspension system to execute a vehicle leveling event including one of adjusting a height of the vehicle or maintaining the height of the vehicle. The process further includes operating programming to, simultaneously with the controlling the pneumatic pressure, utilize a plurality of active sway bars to provide an offset torque to the vehicle body. Each of the plurality of active sway bars is associated with one of a plurality of axles. Providing the offset torque is based upon a number of moles of air in each of the plurality of air spring devices and reducing the longitudinal roll.

Abstract: Systems and methods to perform traffic signal management for operation of autonomous vehicles involve obtaining vehicle data from two or more vehicles at an intersection with one or more traffic lights. The vehicle data includes vehicle location, vehicle speed, and image information or images. A method includes determining at least one of three types of information about the one or more traffic lights based on the vehicle data. The three types of information include a location of the one or more traffic lights, a signal phase and timing (SPaT) of the one or more traffic lights, and a lane correspondence of the one or more traffic lights. The method also includes providing the at least one of the three types of information about the one or more traffic lights for the operation of autonomous vehicles.

Abstract: A system and method for determining a frequency response of a power steering system is disclosed including a steering assist motor configured to generate an assist torque about an axis of a steering shaft when activated. The method includes monitoring, by a controller, a torque transducer that measures a steering output torque of the steering shaft experienced during a first frequency sweep and a second frequency sweep. The method also includes determining, by the controller, a transfer function based on the steering output torque monitored during the first frequency sweep and the second frequency sweep, where the transfer function indicates the response by the power steering system.

Abstract: A method of controlling a vehicle includes receiving a first signal from a user device, which indicates motion of the user device. The method additionally includes receiving first sensor data, which indicates motion of a feature external to the vehicle. The method also includes processing, via a controller, the first sensor data to compare the motion of the user device with the motion of the feature external to the vehicle. The method further includes communicating, via the controller, a second signal to the user device. The second signal indicates motion of the vehicle. The method additionally includes receiving a third signal from the user device. The third signal indicates a correlation between the motion of the vehicle and a motion observed by the user device. The method further includes selectively controlling, via the controller, the vehicle towards the feature based on the processing and on the receiving the third signal.

Abstract: A vehicle crowd sensing system and method of selective sensing for the vehicle crowd sensing system. The method, in one implementation, involves receiving a plurality of detection reports from a first set of vehicles, each detection report including an event, a position qualifier of the event, and a severity qualifier of the event; developing an inherent error model for the event that includes a compilation of the position qualifiers of the event and the severity qualifiers of the event; and determining a resampling instruction for the event. The resampling instruction is based on an action model and the action model is at least partly a factor of the inherent error model.

Abstract: An exemplary method for detecting a lateral oscillation of a vehicle includes monitoring yaw rate data and lateral acceleration data of the vehicle, analyzing the yaw rate and lateral acceleration data to generate a yaw rate signal energy distribution and a lateral acceleration signal energy distribution, determining whether a series of conditions are satisfied; and if the conditions are satisfied, automatically controlling the actuator to reduce the lateral oscillation of the vehicle. In some examples, the series of conditions includes the detection of spikes in the yaw rate and lateral acceleration data at approximately the same frequency, a magnitude of the spikes exceeding a first threshold, and a phase shift between the yaw rate and lateral acceleration data exceeding a second threshold.
