Abstract
A vehicle system controller for a vehicle having an engine, a motor/generator, and subsystem controllers is provided. The vehicle system controller includes a state machine having a number of predefined states which represent vehicle operating modes. The predefined states include a motor drive state, which represents a vehicle operating mode wherein the motor/generator provides all driveline torques. The vehicle system controller further includes a set of rules which define logical relationships between each of the predefined states. A set of commands, unique to each state, are supplied to the subsystem controllers. The commands are provided to the subsystem controllers to achieve desired vehicle functionality within the states, and to transition between different states.
