  • Patent number: 10919428
    Abstract: A powered sliding platform assembly may include an actuator, a platform, and a controller. The platform may have a rail defining first and second openings configured to receive a pin of an actuator. The actuator and the rail may be arranged such that while the platform moves between extended and retracted positions, the pin rides along the rail between the openings. The controller may be programmed to, in response to a signal indicative of an object being proximate the platform, inhibit movement of the platform.

  • Patent number: 10821963
    Abstract: A control strategy is provided for a hybrid vehicle that will increase drivability during low or decreasing driver demands. Coordination between shifting the transmission and stopping or (non-demand) starting of the engine can increase drivability. The vehicle includes a motor/generator with one side selectively coupled to the engine and another side selectively coupled to the transmission. The control strategy acts when an engine start or stop is requested while driver demand is decreasing and a shift of the transmission is demanded. To inhibit these events from proceeding simultaneously, the control strategy delays the engine from starting or stopping until the transmission has finished shifting, or vice versa.

  • Patent number: 10710461
    Abstract: A vehicle includes a traction battery and a controller. The controller, in response to termination of current flow from the traction battery to a tool that is plugged in to the vehicle that results in shutting down of the tool, actuates a switch such that current resulting from the shutting down flows from the tool to the traction battery for regenerative energy capture.

  • Patent number: 10473211
    Abstract: Systems and methods for improving hybrid vehicle cooling are presented. In one example, an electric pump may supply transmission fluid to a transmission and a driveline integrated starter/generator to cool, operate, and lubricate driveline components. The electric pump may be selectively operated to conserve energy and to supply driveline cooling when driveline cooling may be desirable.

  • Patent number: 10336315
    Abstract: A controller and a control strategy minimizes shift shock in a hybrid electric vehicle during a downshift conducted while the vehicle is in a regenerative braking mode by maintaining total powertrain torque at a desired target during the downshift. The controller has three preferable modes including modulating just engine torque, modulating just electric motor torque or simultaneously modulating both motor and engine torque.

  • Patent number: 10005453
    Abstract: A vehicle includes a hybrid powertrain with a motor/generator electrically coupled to a high-voltage bus to provide propulsion. The vehicle also includes an integrated starter/generator electrically copulated to a low-voltage bus and configured to start the engine. A vehicle power system includes a power converter electrically coupled between the high-voltage bus and the low-voltage bus. During engine start events, operation of the integrated starter/generator is coordinated with operation of the power converter to reduce voltage sag on the low-voltage bus. An increase rate of current supplied to the integrated starter/generator is limited such that a current output of the power converter does not saturate at a maximum current output for a period of time after initiating the engine start event.

  • Patent number: 9925972
    Abstract: A method and a system for reducing driveline speed oscillations related to a driveline resonance frequency are described. Driveline speed oscillations may be reduced via slipping a driveline clutch or adjusting torque of a driveline motor/generator. The method and system may be activated during select vehicle operating conditions.

  • Patent number: 9873422
    Abstract: A vehicle includes a motor positioned between an engine and a driveline connected to a vehicle wheel, and a controller. The controller controls engine torque and maintains motor torque during wheel torque and driveline component torque reversals to limit a vehicle output torque rate of change through a lash region associated with a range of driveline torque ratios. A method of controlling a hybrid vehicle includes controlling engine torque to a specified profile and maintaining motor torque at a generally constant value during at least one of wheel torque and driveline component torque reversals to limit a vehicle output torque rate of change through a lash region associated with a range of driveline torque ratios.
