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.

Control architecture for a multi-mode powertrain system

A starter control system is disclosed. In one example, the starter control system may be activated via predetermined control logic or via an operator action that is not subject to the predetermined control logic.

Starter relay control

A starter control system is disclosed. In one example, the starter control system allows both automatic and manual control over an engine starting sequence. The starter control system can enhance starter control system flexibility.
