    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 includes determining a first electrical power loss value of operating first and second electric machines with power inverters of both electric machines in an active mode. The method includes determining at least one of a second and a third electrical power loss value. The second electrical power loss value is with operating with the power inverter of the first electric machine in the active mode and the power inverter of the second electric machine in a standby mode. The third electrical power loss value is with operating with the power inverter of the second electric machine in the active mode and the power inverter of the first electric machine in the standby mode. A controller sets the power inverters in the respective modes corresponding with a lowest of the electrical power loss values.

    Abstract: A hybrid vehicle has a powertrain that includes a transmission with a planetary gear set that has a first, a second, and a third member. An engine is connected for unitary rotation with the first member. A first final drive is operatively connectable with the carrier member and connected with the first axle. A first motor-generator is connected for unitary rotation with the third member. A second motor-generator is operatively connected for proportional rotation with one of the axles. A first clutch is selectively engageable to connect any two of the members for unitary rotation with one another. The planetary gear set provides an underdrive ratio of speed of the second member to speed of the engine when the sun gear member is stationary.

    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.
