Abstract
Methods and systems are provided for expediting updating a vehicle'"'"'s powertrain calibration table. The table is updated with data generated on-board a given vehicle while being matured with data downloaded from a cloud-based network, the downloaded data generated on-board one or more other vehicles having matching powertrain characteristics. Regions of a vehicle'"'"'s calibration table where sufficient data is not generated on-board a given vehicle is populated with data from one or more other vehicles having sufficient data for those corresponding regions.

13. A method, comprising:
-
uploading data collected on-board each of a first and second vehicle having matching powertrain characteristics onto an off-board network; populating a first region of a first calibration table of the first vehicle using data collected on-board the first vehicle; and downloading data collected on-board the second vehicle from the off-board network to populate a second region of the first calibration table. - View Dependent Claims (14, 15, 16, 17)

18. A vehicle system, comprising:
-
an engine; a powertrain coupled between the engine and vehicle wheels; one or more actuators configured to vary a powertrain output; a communication module for communicatively coupling the vehicle system to an off-board cloud network; and a controller with computer readable instructions included on non-transitory memory for; storing data generated on-board the vehicle locally while also uploading the on-board generated data to the off-board cloud network; based on operating conditions at which data was generated on-board the vehicle, and further based on a residence time of the vehicle at the operating conditions, populating one or more cells of a powertrain calibration table; and downloading data corresponding to unpopulated cells of the calibration table from the off-board cloud network, the downloaded data generated on-board one or more other vehicles; and adjusting settings for the one or more actuators based on the calibration table. - View Dependent Claims (19, 20)
