Abstract: A hybrid-electric vehicle having a continuously variable transmission is provided. The continuously variable transmission further includes a forward disconnect clutch configured to selectively couple and decouple the continuously variable transmission and a first set of drive wheels. The hybrid-electric vehicle further includes a rear e-axle assembly, which allows the vehicle to operate in an electric-only mode, in which the vehicle is propelled with power generated solely by at least one electric power component. When the vehicle is operated in electric-only mode, the transmission disconnect clutch is disengaged, such that the continuously variable transmission is decoupled from the first set of drive wheels to allow the continuously variable transmission to operate in a low loss state. A method of transitioning an all-wheel drive hybrid-electric vehicle between an electric only mode and a hybrid mode, i.e., completing a “flying start,” is also provided.

Abstract: A powertrain includes an engine having a crankshaft, a transmission having an input member, and a damper operatively interconnecting the input member and the crankshaft to transmit torque from the crankshaft to the input member. An electric motor/generator is operatively connected to the transmission input member to selectively transmit torque thereto. A damper bypass system is operatively connected to the crankshaft and the input member. The damper bypass system is configured not to transfer torque from the crankshaft to the input member, but transmits torque from the input member to the crankshaft in response to input member torque exceeding crankshaft torque.

Abstract: A vehicle is described that includes a multi-mode powertrain system having a first drive unit and a second drive unit. A controller is arranged to monitor the high-voltage DC power bus and is in communication with and operatively connected to first and second inverters. The controller is able to detect operation of one of the first inverter or the second inverter in an uncontrolled generating (UCG) mode, determine a driveline torque associated with the operating of the one of the first inverter or the second inverter in the UCG mode, and determine a compensating torque that is needed to counteract the driveline torque associated with the operating of the one of the first inverter or the second inverter in the UCG mode. The controller can further operate to detect a fault that may induce unintended lateral motion (ULM), and control torque outputs of the inverters based thereon.

Abstract: A method for controlling a powertrain system includes deactivating a motor disconnect clutch during vehicle operation. Motor speed is decreased to a first inactive speed threshold and an inverter circuit is controlled to an inactive state while monitoring the motor speed. The inverter circuit is deactivated, and when the motor speed decreases to a second inactive speed threshold, the inverter circuit is pulse-activated to operate the electric machine to increase motor speed to the first inactive speed threshold, and then deactivated. The inverter circuit is activated to increase the motor speed to synchronize with speed of the driveline prior to activating the motor disconnect clutch.

Abstract: A method for controlling a hybrid powertrain includes the following steps: (a) receiving, via a control module, a torque request; (b) commanding, via the control module, the first clutch of an automatic transmission to shift to a disengaged position in response to the torque request; (c) commanding, via the control module, an electric motor-generator to transmit torque to an internal combustion engine until a speed of a second clutch is substantially synchronized with a speed of the internal combustion engine; and (d) commanding, via the control module, the second clutch to shift to the engaged position after the speed of the second clutch is substantially synchronized with the speed of the internal combustion engine. The automatic transmission shifts a transmission speed ratio from an initial speed ratio to a subsequent speed ratio when the second clutch is in the engaged position.

Abstract: A system and method of managing power in a hybrid vehicle are provided. The system includes an engine, first and second electronic power components, a power storage device, and a controller. The power storage device is configured to supply a power output to the second electronic power component necessary for the second electronic power component to drive a second set of drive wheels, in an electronic all-wheel drive mode. In steep grade environments, the power storage device is depleted at a higher rate, and may require a power input in addition to the power input of a conventional charge to adequately supply the second electronic power component with adequate power. To provide this power, the controller executes a series of control steps to increase a power output of the first electronic power component, by increasing the speed of the engine, thereby providing continuous power to the power storage device.
