Electric-drive motor vehicles, systems, and control logic for predictive charge planning and powertrain control
ActiveUS20200070679A1Minimize and eliminate relianceInexpensive costHybrid vehiclesCharging stationsDriver/operatorElectric cars
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.

Presented are vehicle charging systems and control logic for provisioning vehicle grid integration (VGI) activities, methods for making / using such charging systems, and electric-drive vehicles with intelligent vehicle charging and VGI capabilities. A method of controlling charging operations of electric-drive vehicles includes a vehicle controller detecting if a vehicle is coupled to an electric vehicle supply equipment (EVSE), and determining if the vehicle's current mileage exceeds a calibrated mileage threshold. Responsive to the vehicle being connected to the EVSE and the vehicle's current mileage exceeding the calibrated mileage threshold, the controller determines the current remaining life of the vehicle's traction battery pack and the current time in service of the vehicle. The vehicle controller determines if the current remaining battery life exceeds a predicted remaining battery life corresponding to the current time in service. If so, the vehicle controller enables the traction battery pack to transmit electrical power to the EVSE.
