Abstract: A method for powerhop identification and mitigation includes receiving sensor data of a vehicle, such as wheel speed; determining a wheel jerk characteristics of the vehicle based on the wheel speed; determining a ride height of the vehicle; determining whether the vehicle is experiencing powerhop based on the wheel jerk characteristics and the ride height of the vehicle; and in response to determining that the vehicle is experiencing powerhop, adjusting a torque of the vehicle to mitigate the powerhop.

Abstract: A vehicle control system for driving behavior vehicle detection includes at least one vehicle object detector configured to detect motion of target vehicles within an object detection range of a host vehicle, a vehicle user interface configured to display a visual indication to a driver of the host vehicle, and a vehicle control module configured to obtain detected motion parameters of the one or more target vehicles via the at least one vehicle object detector, determine a hazard index for each of the one or more target vehicles, according to the detected motion parameters, and in response to the hazard index exceeding a specified threshold value for at least one of the one or more vehicles, update the vehicle user interface to provide a visual notification of identified driving behavior exceeding the specified threshold value for the at least one of the one or more target vehicles.

Abstract: A fault remediation system for a vehicle includes one or more controllers in electronic communication with one or more consumed interfaces and one or more provided interfaces. The one or more controllers execute instructions to receive, from the one or more consumed interfaces, a consumed signal and perform fault detection upon the consumed signal to determine the presence of an active fault within the consumed signal. In response to detecting an active fault with the consumed signal, the one or more controllers select a remediation state from a group of two or more prospective remediation states based on a significance analysis of the consumed signal. The one or more controllers evaluate a relevant subfunction that corresponds to the consumed signal that the remediation state addresses for the presence of remediation tolerance and generates arbitration instructions based on the remediation tolerance.

Abstract: Systems and methods of alerting an occupant of a vehicle to an obstacle to a side of the vehicle. The systems and methods include receiving turn indicating data from at least one vehicle system, receiving perception data from a perception system of the vehicle, predicting a vehicle turn based on the turn predicting data, generating an obstacle alert, which is output through an output device of the vehicle, when an obstacle is detected within a first sized detection zone or a second sized detection zone using the perception data, and switching from using the first sized detection zone to using the second sized detection zone for generating the obstacle alert in response to predicting the vehicle turn. The second sized detection zone is extended as compared to the first sized detection zone.

Abstract: A system for adaptive tire force prediction in a motor vehicle includes a control module that executes program code portions that receive real-time static and dynamic data from motor vehicle sensors, that model forces at each tire of the motor vehicle at one or more incremental time steps, that estimate actual forces at each tire of the motor vehicle at each of the one or more incremental time steps, that adaptively predict tire forces at each tire of the motor vehicle at each of the one or more incremental time steps, that generate one or more control commands for actuators of the motor vehicle, that capture discrepancies between real-time force estimations and nominal force calculations at each tire of the motor vehicle, and that apply compensation parameters to reduce tracking errors in the one or more control commands to the one or more actuators of the motor vehicle.

Abstract: A data analytics system for a vehicle includes one or more controllers having a multi-layered control software architecture including two or more software layers and a health monitoring structure. The one or more controllers execute instructions to receive a fault, and in response to receiving the fault, generate, by the health monitoring structure, a plurality of unique triggers as the fault propagates throughout the multi-layered control software architecture. The controllers build a network including a plurality of propagation paths and identify one or more main propagation paths that are part of the network based on a data analysis of a mock big data set. The one or more controllers build a complete propagation pathway including two or more main propagation paths. In response to determining only one main propagation path, the controllers determine a root cause of the fault based on the only one main propagation path.
