Abstract: A propulsion system, control system, and method are provided that use model predictive control to generate an initial selected engine output torque value. A minimum torque limit is determined by selecting a minimum acceptable engine output torque. A maximum torque limit is determined by selecting a maximum acceptable engine output torque. A desired engine output torque value is set as: a) the minimum torque limit, if the initial selected engine output torque value is less than the minimum torque limit; b) the maximum torque limit, if the initial selected engine output torque value is greater than the maximum torque limit; or c) the initial selected engine output torque value, if the initial selected engine output torque value is neither greater than the maximum torque limit nor less than the minimum torque limit.

Abstract: A method for controlling engine torque in a vehicle during a default throttle condition includes determining whether a throttle of the engine is in a default throttle condition, determining whether the engine is producing more torque than desired if the throttle of the engine is in the default throttle condition, and applying an accessory load to the engine if the engine is producing more torque than desired in the default throttle condition.
