    Abstract: Methods and apparatus are provided for selecting a computational platform. The method includes collecting platform feature data for each of a plurality of existing computational platforms in a particular class of computational platforms. The platform feature data for each of the plurality of existing computational platforms includes a plurality of design parameters and a performance measurement for the computational platform to complete a benchmarking software component. The method further includes training a mathematical model using the collected platform feature data to devise a predictive model for predicting a predicted performance measurement for a computational platform in the particular class of computational platforms when provided with design parameters, predicting, with the predictive model, the predicted performance measurement of a new computational platform that is not available for testing, and selecting a computational platform using the predicted performance measurement.

    Abstract: Presented are scenario-planning and route-generating distributed computing systems, methods for operating/constructing such systems, and vehicles with scenario-plan selection and real-time trajectory planning capabilities. A method for controlling operation of a motor vehicle includes determining vehicle state data, such as a current position and velocity of the vehicle, and path plan data, such as an origin and desired destination of the vehicle. A remote computing node off-board from the motor vehicle generates a list of trajectory plan candidates based on the vehicle state data, the path plan data, and current road scenario data. The remote computing node then calculates a respective travel cost for each candidate in the trajectory plan candidates list, and sorts the list from lowest to highest travel cost. The candidate with the lowest travel cost is transmitted to a resident vehicle controller. The vehicle controller executes an automated driving operation based on the received trajectory plan candidate.

    Abstract: A vehicle system controller having an asymmetric system architecture and a method of operating the vehicle system controller is provided. The vehicle system controller includes a primary controller and a secondary controller in communications with the vehicle systems. Each of the controllers include a memory unit containing software application and a processor for executing the software to generate commands for the vehicle systems. The memory unit of the secondary controller contains only a subset of the total software applications contained in the memory unit of the primary controller. The subset of software applications is only for the operation of pre-identified features of the vehicle systems. The vehicle systems are configured to default to commands from the primary controller, but switches to the commands from the secondary controller for a predetermined length of time if the primary controller becomes fail-silent.

    Abstract: Method and systems for one-pedal driving (OPD) control for a vehicle. The methods and systems determine that regenerative braking is to be applied based on accelerator pedal stroke data, predict an upcoming deceleration event based on sensor data from a sensor system of the vehicle, thereby providing deceleration prediction data, adjust a default braking profile based on the deceleration prediction data, generate a regenerative braking command based on the accelerator pedal stroke data and the adjusted braking profile, and output the regenerative braking command to a motor/generator of the vehicle.
