Abstract:
1. An engine control system comprising: 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 that generates ABA predicted and immediate torque requests based on the driver input; a speed control (SC) module that generates a first set of SC predicted and immediate torque requests based on engine speed; a propulsion torque arbitration (PTA) module that 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 that controls output torque of an engine based on the PTA predicted and immediate torque requests; and a zero pedal torque module that generates a zero pedal torque signal based on a friction torque and a transmission load torque; and a revolutions per minute (RPM) control module that generates a second set of SC predicted and immediate torque requests based on the zero pedal torque signal.
