Abstract: A vehicle and method is provided. The vehicle includes systems and method for limiting the slip of the wheels. In an embodiment, the system holds the brakes based on an acceleration characteristic measured by a sensor. In another embodiment, the system includes a transmission controller that applies an adjustment to limit an amount of clutch slip as the clutch temperature to change in clutch performance to reduce wheel slip. In another embodiment, the system monitors wheel slip signal from a sensor and compares the wheel slip to a target slip value and controls clutch slip of the transmission clutch based to maintain engine output torque during acceleration. In another embodiment, in response to an anticipated vehicle launch event, a drive motor applies a first torque to the input shaft to adjust a gear lash of the differential unit.

Abstract: An electrified powertrain system for a vehicle includes an electric machine coupled to a driveline. An inverter controller communicates directly with an auxiliary power module. An ignition module indicates either a key-on state or a key-off state. When the ignition module is in a key-off state, a low-power DC/DC converter generates an output voltage originating on the high-voltage DC bus having a magnitude sufficient to activate the inverter controller. The inverter controller detects a key-off uncontrolled generator (UCG) mode. The inverter controller directly communicates detection of the key-off UCG mode to the auxiliary power module. The inverter controller controls the inverter. The auxiliary power module supplies electric power to operate low-voltage electrically-powered powertrain actuators.

Abstract: A vehicle system includes an electric motor, an internal combustion engine, and a heating system configured to transfer heat from the internal combustion engine to a passenger compartment of the vehicle. The system includes a controller configured to operate the electric motor and the internal combustion engine according to one of a plurality of drive cycle profiles. The controller selects the drive cycle profile based on an ambient temperature. The drive cycle profiles include a first drive cycle profile that commands power from the electric motor until the battery system reaches a predetermined state of charge and subsequently commands power from the internal combustion engine and a second drive cycle profile that commands power from the internal combustion engine and subsequently commands power from the electric motor.

Abstract: A method and system used to identify an optimal hybrid vehicle operating mode based on a variety of potential factors, and then recommend the optimal operating mode to the driver so that they can make an informed decision regarding their operating mode selection. In one embodiment, the method uses geographic-, vehicle- and/or environmental-related factors to establish one or more operating zones, monitors the location of the hybrid vehicle and determines when it is within one of the operating zones, and then determines an operating mode that is optimal for that particular operating zone.
