Abstract

An engine control system includes a mode selection module that is configured to select an operating mode from one of an open loop control mode, a torque control mode, and a speed control mode based on an engine speed and a driver input. An axle torque arbitration (ABA) module generates ABA predicted and immediate torque requests based on the driver input. A speed control (SC) module generates a first set of SC predicted and immediate torque requests based on engine speed. A propulsion torque arbitration (PTA) module generates PTA predicted and immediate torque requests based on one of the ABA predicted and immediate torque requests and the first set of SC predicted and immediate torque requests based on the operating mode. A torque output control module controls output torque of an engine based on the PTA predicted and immediate torque requests.
