Abstract: A vehicle includes a combustion engine having at least one cylinder to burn a fuel, and a fuel injector to supply a fuel mass to the at least one cylinder. The vehicle also includes a controller programmed to cause the fuel injector supply a series of fuel pulses that sum to an aggregate target fuel mass. The controller is also programmed to adjust a commanded duration of a subsequent pulse of the series of pulses from a target pulse duration value based on at least one of a dwell time since a preceding pulse, a fuel mass of the preceding pulse, and an opening delay of the preceding pulse.

Abstract: Presented are intelligent vehicle systems and control logic for predictive charge planning and powertrain control of electric-drive vehicles, methods for manufacturing/operating such systems, and electric-drive vehicles with smart charge planning and powertrain control capabilities. Systems and methods of AI-based predictive charge planning for smart electric vehicles use machine-learning (ML) driver models that draws on available traffic, location, and roadway map information to estimate vehicle speed and propulsion torque requirements to derive a total energy consumption for a given trip. Systems and methods of AI-based predictive powertrain control for smart hybrid vehicles use ML driver models with deep learning techniques to derive a drive cycle profile defined by a preview route with available traffic, geopositional, geospatial, and map data. ML-generated driver models are developed with collected data to replicate driver behavior and predict the drive cycle profile, including predicted vehicle speed, propulsion torque, and accelerator/brake pedal positions for a preview route.

Abstract: A vehicle includes a combustion engine having at least one cylinder to burn a fuel and a fuel injector to selectively supply fuel to the cylinder. The vehicle also includes a controller programmed to issue a series of fuel pulse commands to actuate the fuel injector to supply a corresponding series of fuel pulses that sum to an aggregate target fuel mass. The controller also monitors a closed-loop feedback signal indicative of a change in an opening delay between an individual one of the series of fuel pulse commands and a responsive fuel pulse. The controller is further programmed to adjust a subsequent one of the series of fuel pulse commands to incorporate the change in opening delay.

Abstract: A diagnostic system for a vehicle includes a vehicle system configured to operate the vehicle in a normal operating mode and a boosted mode. In the boosted mode, the vehicle system increases at least one of a maximum motor torque, a maximum engine torque, and a maximum battery power available to the vehicle. A wear estimation module is configured to collect wear data associated with a component of the vehicle while being operated in the boosted mode, estimate, based on the collected wear data, wear of the component caused by being operated in the boosted mode, and generate a prediction of a remaining lifetime of the component based on the estimated wear of the component.

Abstract: A vehicle includes an engine having a combustion cylinder, and at least one fuel injector configured to supply a number of fuel pulse to the cylinder. A controller is programmed to issue a first fuel pulse command to actuate the fuel injector allowing fuel to pass through the fuel injector as a first fuel mass. The controller is also programmed to monitor a voltage across the fuel injector, and determine a preliminary fuel injector opening magnitude based on a rate of change of voltage. The controller is further programmed to assign the preliminary fuel injector opening magnitude as a maximum fuel injector opening magnitude in response to the first fuel mass being greater than a quantity threshold. The controller is further programmed to apply a scaling factor to adjust a second fuel pulse command to normalize the maximum fuel injector opening magnitude value to a predetermined full open value.
