Abstract: A braking system for a vehicle includes devices that are configured to apply braking force to a wheel in response to a braking command. A first sensor is disposed to monitor a parameter associated with the braking force, and a spatial sensor is disposed to determine a linear range between the vehicle and a predefined locus point. A controller is operatively connected to the braking system and in communication with the first sensor and the spatial sensor. The controller detects a braking event and determines a time to stop and an applied braking force during the braking event, which is integrated over the time to stop. The braking system is evaluated based upon the total stopping distance and the integrated applied braking force during the braking event. A fault associated with the braking system is determined based upon the evaluation of the braking system.

Abstract: A vehicle includes a brake system configured to resist vehicle movement. The vehicle also includes at least one controller in communication with the brake system. The controller is programmed to detect an initiation of a braking event and monitor raw signal data associated with the brake system during the braking event. The controller is also programmed to generate a feature data set based on the raw signal data that is indicative of performance of at least one component of the brake system. The controller is further programmed to identify a vehicle maneuver class based on a rate of change of vehicle movement, store the feature data set and the identified vehicle maneuver class as a data vector, and transmit the data vector to a processor.

Abstract: A method for dynamically determining a mass of a vehicle including a propulsion system coupled to a drive wheel is described, and includes monitoring vehicle operating conditions, executing an event-based estimation method based upon the vehicle operating conditions to determine a first vehicle mass state, and executing a recursive estimation method based upon the vehicle operating conditions to determine a second vehicle mass state. A final vehicle mass is determined based upon the first and second vehicle mass states.

Abstract: A vehicle braking system including a brake pedal in communication with a wheel brake, a brake actuation system, a braking system controller, an on-board driver communication system, and a controller is described. Parameters associated with a braking request, a brake actuation command and vehicle operation are monitored during each braking event, and segmented the into parameters associated with a static portion of the braking event and parameters associated with a dynamic portion of each braking event, evaluate the parameters associated with the static portion of the braking event and evaluate the parameters associated with the dynamic portion of the braking event, and assess a state of health of the braking system based upon the evaluation of the parameters. The assessment of the state of health of the braking system is communicated to a vehicle driver via the on-board driver communication system.

Abstract: Systems and method are provided for collaboration between autonomous vehicles. In one embodiment, a processor-implemented method for coordinating travel between multiple autonomous vehicles is provided. The method includes sending a collaboration request to one or more vehicles in an area to form a group to perform a mission, receiving an acceptance of the collaboration request to join the group wherein the group includes a plurality of vehicles, cooperating in assigning leading functions for the group to one or more of the plurality of vehicles in the group, cooperating in mission negotiations for the group, cooperating in determining a formation for the group, and cooperating in generating a trajectory for the group. The vehicles in the group are operated in accordance with the determined formation and generated trajectory.

Abstract: A method for planning and adapting a recommended travel route to a route destination for a vehicle having various subsystems includes identifying the route destination and receiving vehicle health management (VHM)/state of health (SOH) information for each subsystem. The vehicle with a controller programmed to execute the method is also disclosed. The method includes calculating route characteristics of candidate travel routes to the destination using the VHM information and determining, from among the candidate travel routes, travel routes for which the characteristics meet a respective threshold requirement. Thereafter, the controller executes a control action by displaying a candidate route meeting the threshold requirements. An occupant is prompted to revise the mission requirements when no candidate route exists. A default route to a designated parking location or repair depot may be displayed when none of the candidate routes meet the threshold requirements.
