Embodiment Construction

[0017] Provides for acceleration for optimizing vehicle systems (for example, figure 1 A method and system for updating one or more calibration tables output by a powertrain in a vehicle system for a vehicle. In one non-limiting example, the engine can be configured as figure 2 Shown, where the engine includes at least one cylinder, a control system, a turbocharger, and an exhaust gas recirculation system, among other features. The engine controller can be configured to execute a control program (eg, Figure 3-Figure 5 program) to update the vehicle calibration table based on the on-board data and / or the off-board data, and optimize the vehicle powertrain output based on the updated calibration table. Off-vehicle network data can be obtained from the Figure 1-Figure 2 download from the off-board network system described here. exist Image 6 An example adaptation of a vehicle calibration table is shown at .

Abstract

The present invention relates to methods and systems for engine and powertrain control. Methods and systems are provided for expedited updating of a powertrain calibration table for a vehicle. The table is updated with data generated on a given vehicle while being completed with data downloaded from a cloud-based network generated on one or more other vehicles with matching drivetrain characteristics. Areas of the calibration table for vehicles for which sufficient data was not generated on a given vehicle are populated with data from one or more other vehicles for which those corresponding areas have sufficient data.

Description

technical field [0001] The present application relates to systems and methods for improving calibration of engine and powertrain output. Background technique [0002] Various calibration tables and maps may be used by the engine control system to optimize engine and drivetrain output as operating conditions change during the drive cycle. For example, a vehicle system may be pre-installed using an engine map that is used by the engine control system to determine how to schedule various actuators. Calibration charts and tables may be populated with data collected during engine and powertrain design, testing and experimentation. Additionally, the engine control system can be enabled to adapt and update calibration tables using measurements and feedback data. [0003] However, as drivetrains and combustion engines become more complex, there are many degrees of freedom to optimize engine and drivetrain output. For example, there may be various combinations of possible variable...
