  • Publication number: 20210061278
    Abstract: A method for controlling automated driving operations of a vehicle includes determining vehicle origin and destination data, and generating a graphical representation of a road network with multiple candidate routes between the vehicle's origin and destination. Road-level data, including speed, turn angle, and/or gradient data, is received for each candidate route, and respective total energy uses are estimated for the vehicle to traverse across the candidate routes. Multiple candidate driving strategies, each having respective speed and acceleration profiles, are determined for the candidate route with the lowest estimated total energy use. An optimal candidate driving strategy is selected through a cost evaluation of the associated speed and acceleration profiles and forward movement simulations of the vehicle over a prediction horizon.

    Abstract: A method for controlling continuous and discrete actuators (e.g., modes) in a powertrain system includes receiving preview information from a sensor(s) describing an upcoming dynamic state at a future time point, and providing control inputs for the actuators to a controller that includes the preview information. The input set collectively describes a future torque or speed output state at the future time point. The controller processes the input set via a dynamical predictive model, in real time, to determine control solutions to take at the present time point for implementing the dynamic state at the future time point. A lowest opportunity cost control solution is determined and optimized. The controller executes the optimized solution at the present time step.

  • Publication number: 20200224601
    Abstract: A method of diagnosing a propulsion system implements a top-down hierarchical examination procedure, in which the propulsion system is analyzed as a whole to determine if the propulsion system is healthy. Data from a first set of vehicle sensors is compared to a system-healthy data cluster to determine if the propulsion system is healthy or unhealthy. If the propulsion system is unhealthy, then a plurality of subsystems of the propulsion system are each analyzed at a first examination level using selective data from the sensors to identify one of the subsystems as an unhealthy subsystem. A plurality of component systems of the unhealthy subsystem are then analyzed at a second examination level using other selective data from the sensors to identify one of the component systems of the unhealthy subsystem as an unhealthy component system.
