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: A system for data processing and storage in vehicles having a zone-based, central computing in-vehicle communications network architecture, includes a zone control unit (ZCU) that receives electronic messages from one or more sensors or electronic control units (ECUs) located within a zone of the vehicle, the ZCU comprising a protocol data unit (PDU) gating module that converts the electronic messages into a plurality of PDUs, and a switch-based Ethernet network that transmits the plurality of PDUs, using Ethernet protocol frames comprising the plurality of PDUs, to a central computing platform. The central computing platform includes an Ethernet handler module that decomposes the Ethernet protocol frames into individual PDUs for storage in a shared memory. The central computing platform further includes a plurality of parsing modules that are configured to access the individual PDUs from the shared memory and perform data processing on the individual PDUs.

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: A method for optimizing inter-vehicle order and distance includes communicating vehicle characteristics representative of a first and at least one second vehicle as the first vehicle approaches the at least one second vehicle. Based on the vehicle characteristics, a position in a driving order of the first vehicle with respect to the at least one second vehicle is selected and executed. A real-time fuel economy is recorded as the vehicle in the trailing position moves from a maximum following distance to a minimum following distance from the vehicle in the lead position. Based on at least the recorded real-time fuel economy, an optimal inter-vehicle distance between the vehicles in the lead and trailing positions is selected and executed.

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.
