Abstract: An inverter power module: selectively applies power from a battery to a permanent magnet (PM) electric motor; and selectively provides power output by the PM electric motor for the battery. A switch, when open, prevents power flow the inverter power module from the battery, and, when closed, enables power flow between the inverter power module and the battery. An adjustment module determines an SOC adjustment based on at least one of a vehicle speed and a temperature of the battery. A maximum module receives a first maximum SOC of the battery and that determines a second maximum SOC of the battery based on the first maximum SOC and the SOC adjustment. A clutch control module disengages a clutch, decoupling the PM electric motor from a transmission, when the switch is stuck closed and an SOC of the battery is greater than the second maximum SOC.

A second planetary gear set is coupled to the second electric device. The output is coupled to both the first planetary gear set and the second planetary gear set. The input is connected to the first planetary gear set. A fixed ratio gear reduction system couples the input and the second planetary gear set.

Abstract: A method of prioritizing power output of first and second power-sources in a vehicle includes identifying, via a controller communicating with a satellite, the vehicle's position on a specific road course. The method also includes receiving a request for total amount of power from both power-sources and determining first power-source power and available second power-source target maximum power based on the vehicle position. The method also includes determining, based on the vehicle position, a minimum energy reserve of a source configured to energize the second power-source and available second power-source power based on the determined reserve. The method also includes subtracting the first power-source power from the requested total amount of power to determine a requested second power-source power. Furthermore, the method includes comparing the available and the requested second power-source power and generating the smaller power value to minimize the time for the vehicle to traverse the road course.

Abstract: A powertrain system includes an internal combustion engine having a crankshaft that fixedly couples to an input member of a multi-mode transmission including first and second torque machines. The transmission operates in one of a plurality of fixed-gear modes and variable modes through selective activation of first and second clutches. A control method includes, in response to a command to operate the multi-mode transmission in a fixed-gear mode, activating only the first clutch and commanding the engine to an OFF state. The first torque machine is controlled to generate a first torque output responsive to a drag torque that is offset by an engine reactive torque with the engine in the OFF state. The transmission operates in the fixed-gear mode by controlling the second torque machine to generate a second torque output responsive to an operator torque request and the first torque output of the first torque machine.

Abstract: A method for operating a powertrain system includes executing a transmission shift between an initial electrically-variable transmission (EVT) range and a target EVT range. The transmission shift includes transitioning to operating with three speed degrees of freedom including controlling speed of a second torque machine to synchronize speed of an oncoming clutch associated with the target EVT range and coincidentally controlling speeds of a first torque machine and an engine to achieve a preferred speed of the output member of the transmission. The transmission shift further includes controlling torque output from the first torque machine in response to an output torque request, and activating the oncoming clutch upon synchronizing the speed of the oncoming clutch. Subsequent to the transmission shift, the powertrain system is operated in the target EVT range.
