    摘要: A method of output torque smoothing for a hybrid powertrain having an electric machine and a spark ignition engine with a first cylinder and a second cylinder includes commanding a fuel-cut transition, including consecutively initiating and completing deactivation of the first cylinder and initiating and completing deactivation of the second cylinder. The fuel-cut transition is characterized by an absence of retarding spark to the first cylinder and second cylinder. Fuel is supplied to the first cylinder until the first cylinder completes deactivation and to the second cylinder until the second cylinder completes deactivation. The electric machine captures a first torque from the first cylinder by generating electricity until the first cylinder completes deactivation and captures a second torque from the second cylinder by generating electricity until the second cylinder completes deactivation.

    摘要: Example embodiments disclosed herein relate to a storage device. The storage device may include a mechanism that monitors for receipt of cached authentication data from a host computing device upon resuming operation from a standby mode of the host computing device. The storage device may further include a mechanism that unlocks the storage device in response to receipt of the cached authentication data from the host computing device. In addition, the storage device may include a mechanism that monitors for receipt of re-authentication data and a mechanism that locks the storage device when a predetermined period of time has passed since resuming operation from the standby mode without receipt of the re-authentication data. Related computing devices, methods, and machine-readable storage media are also disclosed.

    摘要: A system comprises a first operating environment and a second operating environment. The first and second operating environments exchange information in encrypted form using a shared encryption key (K3). The first and second operating environments cooperate to change the encryption key K3 using another shared encryption key (K4). The encryption key K4 is changed upon the encryption key K3 being changed.

    摘要: A storage device includes storage media and a controller to control access of the storage media. The controller receives an erase command used to specify an erase operation of at least one portion of the storage media. The erase command has a control field controllable by a requestor device that submitted the erase command to the storage device, where the control field has one or more portions settable to cause the storage device to perform one or more of: reporting a progress of the erase operation, and modifying an operational state of the erase operation.

    摘要: A method is provided for controlling engine stop position in a vehicle having an engine with auto stop/auto start functionality. The method includes automatically ramping down engine speed upon initiation of an auto stop event, executing closed-loop speed control of the engine when the engine speed begins to ramp down, and for as long as the engine speed remains above a threshold engine speed while ramping down the engine speed; executing closed-loop position control of the engine while ramping down the engine speed once the engine speed is less than the threshold engine speed and greater than zero; and stopping the crankshaft to within a calibrated range of a targeted engine stop position. A controller is also provided that includes a hardware module and an algorithm adapted for executing the foregoing method, and a vehicle is provided having an engine with auto stop/start functionality and the controller noted above.
