  • Control architecture for a multi-mode powertrain system
    Patent number: 9073544
    Abstract: A controller architecture for a vehicle including a multi-mode powertrain system includes an engine controller having a control routine for determining and executing engine torque commands responsive to a hybrid engine torque command, and a control routine for determining a propulsion axle torque command responsive to an output torque request. The controller architecture further includes transmission controller having a control routine for selecting and effecting operation of the passive transmission in a preferred gear responsive to the output torque request. The controller architecture further includes a hybrid controller having control routines for determining and executing torque commands for each of the non-combustion torque machines and for determining the hybrid engine torque command to achieve a desired axle torque in response to the propulsion axle torque command with the passive transmission operating in the preferred gear.

  • CONTROLLED VEHICLE SHUTDOWN SYSTEM
    Publication number: 20050029869
    Abstract: A vehicle shutdown system (10) includes an ignition-enabling device (14) that has an ON state and an OFF state. A controller (18) that has multiple functions is coupled to the ignition-enabling device (14). The controller (18) temporarily maintains operation of the controller functions when the ignition-enabling device (14) is switched to the OFF state.
