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.

Presented are battery pack voltage-switching (“V-switch”) systems, methods for making / operating such systems, and multi-pack, electric-drive motor vehicles with battery pack V-switch capabilities. A method for controlling operation of a vehicle includes a vehicle controller receiving a voltage switch signal to change a voltage output of the vehicle's battery system. The vehicle controller determines if a speed of a traction motor is less than a calibrated base speed; if so, the controller transmits a pack isolation signal to a power inverter to electrically disconnect the traction battery packs from the traction motor. The vehicle controller determines if a bus current of a DC bus is less than a calibrated bus current threshold; if so, the controller transmits an open signal to open one or more pack contactor switches and a close signal to close one or more pack contactor switches thereby causing the vehicle battery system to output the second voltage.

Presented are dual-clutch engine disconnect devices, methods for making / using such disconnect devices, and motor vehicles equipped with such disconnect devices. An engine disconnect device for a vehicle includes a first one-way clutch (OWC) with concentric inner and outer races and torque elements interposed between and transferring torque across these races in a first direction. The first outer race rigidly attaches to a damper plate for common rotation therewith, and the first inner race rigidly attaches to a pump cover of a torque converter for common rotation therewith. A second OWC, which concentrically aligns within the first OWC, includes concentric inner and outer races with torque elements interposed between and transferring torque across these races in a second direction. The second outer race is splined to the first inner race for common rotation with the pump cover. The second inner race rigidly attaches to the damper plate for common rotation therewith.

Presented are torque converters (TC) with planetary-type vibration dampers, methods for making / using such TC assemblies, and vehicles equipped with such TC assemblies. A TC assembly includes a TC housing drivingly connected to a prime mover to receive torque therefrom, and a TC output member drivingly connected to a transmission to transfer torque thereto. Rotatably mounted within an internal fluid chamber of the TC housing are juxtaposed turbine and impeller blades. The impeller blades are rotatably mounted to the housing. A TC clutch is operable to lock the TC housing to the TC output member. A torsional vibration damper, which is disposed within the internal fluid chamber, includes a sun gear attached to the TC output member for unitary rotation, a ring gear attached to the TC clutch for unitary rotation, and a planet carrier intermeshed with the ring and sun gears and attached to the turbine blades for unitary rotation.

Presented are engine-disconnect clutches with attendant control logic, methods for making / operating such disconnect clutches, and hybrid electric vehicles (HEV) equipped with an engine that is coupled to / decoupled from a transmission and electric motor via a disconnect clutch. A representative method for controlling an HEV powertrain includes receiving an HEV powertrain operation command, then determining a clutch mode of a multi-mode clutch device to execute the HEV powertrain operation. This multi-mode clutch device is operable in: a lock-lock mode, in which the clutch device transmits torque to and from the engine; a free-free mode, in which the clutch device disconnects the engine's output member from the transmission's input member, preventing torque transmission to and from the engine; a lock-free mode, in which the clutch device transmits torque from but not to the engine; and, a free-lock mode, in which the clutch device transmits torque to but not from the engine.

A method for operating an advanced driver assistance (ADAS) system of a motor vehicle includes a vehicle controller receiving, from side and end cameras mounted to the vehicle, camera signals indicative of real-time images of outboard-facing side and end views of the vehicle. The controller determines a region of interest (ROI) inset within each end / side view within which is expected foreign objects and / or hazards. These ROIs are analyzed to detect if a foreign object / hazard is present in the vehicle's end and / or side views. Responsive to detecting the foreign object / hazard, movement of the foreign object / hazard is tracked to determine if the foreign object / hazard moves towards or away from the vehicle's underbody region. If the foreign object / hazard moves to the underbody region, control signals are transmitted to the vehicle's propulsion and / or steering system to automate preventative action that prevents collision of the vehicle with and / or removes the foreign object / hazard from the underbody.
