Abstract: A method to identify lane-level road congestion includes: modeling a lane-level congestion evolution process as a 2-dimensional (2D) Markov chain having multiple vehicles moving through a predetermined segment of a road; aggregating a volume of the multiple vehicles over a predetermined unit of time moving through the predetermined segment of a road; populating a lane congestion map identifying individual road lanes having differing levels of congestion; directing an output of the lane congestion map and an output of a lane congestion model to a lane routing engine; and identifying routes and route changes for a host vehicle to apply to improve a host vehicle estimated time of arrival (ETA) at a predetermined finish location.

Abstract: A method to incorporate lane level road congestion to enhance vehicle navigation includes: collecting vehicle data from a fleet of vehicles; identifying a lane level distribution of multiple vehicles operating on a road having multiple lanes including a host vehicle; comparing the lane level distribution against a non-congested lane of the road; and identifying if a lane level congestion is occurring in at least one of the multiple lanes.

Abstract: A computer is provided for a system for detecting, characterizing, and mitigating road network congestion. The system includes a plurality of motor vehicles. Each motor vehicle includes a telematics control unit (TCU) for generating one or more location signals for a location of the associated motor vehicle and one or more event signals for an event related to the associated motor vehicle. The computer includes one or more processors for receiving the location signal and/or the event signal from the TCU of the associated motor vehicles. The computer further includes a non-transitory computer readable storage medium (CRM) including instructions, such that the processor is programmed to identify a location of the road network congestion at a current time step. The processor is further programmed to track the road network congestion and predict the road network congestion at a next time step.

Abstract: A vehicle off-guard monitoring system includes an automobile vehicle having multiple sensor inputs capturing sensor data representing hazards including garage fires, excessive water or flooding, rain, snow, and at least one person loitering proximate to the automobile vehicle. A database has multiple saved images of the hazards. A computer compares the multiple saved images to the sensor data captured by the multiple inputs to identify if at least one match exists between any one of the multiple saved images of the hazards and the sensor data and when the at least one match exists generating a predefined warning signal. A smart-phone application in communication with the computer and a remote system signals the predefined warning signal to a user of the automobile vehicle to mitigate against damage occurring to the automobile vehicle.

Abstract: A radiant heating and blocking shade system for a sunroof of a vehicle includes a first roller configured to be mounted adjacent to one end of a sunroof of a vehicle. A second roller is mounted adjacent to the first roller between the first roller and the sunroof. A radiant heating shade is at least partially wound around the first roller. The radiant heating shade has a deployed position and a retracted position. A blocking shade is at least partially wound around the second roller. The blocking shade has a deployed position and a retracted position. The blocking shade is arranged parallel to and spaced from the radiant heating shade between the radiant heating shade and the sunroof when the blocking shade and the radiant heating shade are in the deployed position.

Abstract: A method and system of diagnosing and suggesting least probable faults for an exhibited vehicle failure. The method includes initiating a vehicle health management (VHM) algorithm to monitor a state of health (SOH) for at least one vehicle component at each vehicle operating event over a predetermined time period. The VHM algorithm determines at least one of a Green SOH, a Yellow SOH, and a Red SOH designation with a confidence level for the at least one vehicle component; calculating a number of Green SOH designations (Ncalculated) over the predetermined time period; and upon an exhibited vehicle failure, providing a least probable cause indication for the at least one component when a set of conditions are met. The set of conditions includes (i) Ncalculated is equal to or greater than a predetermined number of Green SOH designations and (ii) no Yellow SOH and Red SOH designations are present.

Abstract: System and method for controlling operation of a vehicle in real-time with a supervisory control module. A fault detection module is configured to receive respective sensor data from one or more sensors in communication with the vehicle and generate fault data. The supervisory control module includes at least one fault-tolerant controller configured to respond to a plurality of faults. The supervisory control module is configured to receive the fault data. When at least one fault is detected from the plurality of faults, the supervisory control module is configured to employ the fault-tolerant controller to generate at least one selected command.

Abstract: A scheduling controller in communication with a plurality of autonomous vehicles is described, and includes an operator request compiler, a fleet state-of-health database, an environmental conditions compiler and a fleet scheduling controller. The fleet scheduling controller is configured to deploy the autonomous vehicles based upon inputs from the operator request compiler, the fleet state-of-health database and the environmental conditions compiler. A process for coordinating a fleet of autonomous vehicles includes determining states of health for the autonomous vehicles, and determining a desired autonomous vehicle use requirement from each of a plurality of operators that are associated with the autonomous vehicles. A usage schedule for each of the autonomous vehicles is determined based upon the states of health and the desired autonomous vehicle use requirements from the operators. The autonomous vehicles are deployed based upon the usage schedule.
