A method of operating an engine control system includes reducing pressures within cylinders of an engine based on an auto start command signal including: receiving a torque request signal; calculating a powertrain output torque; and controlling air flow to the engine based on the powertrain output torque. During a startup of the engine: electric motor torque is increased to a predetermined level and reduced to increase a current speed of the engine; combustion torque of the engine is activated and increased after the current speed is within a predetermined range and a manifold absolute pressure is less than a predetermined level; and the electric motor torque is increased based on a crankshaft output torque signal to increase a crankshaft output torque subsequent to the reducing of the electric motor torque and while performing the activating of the combustion torque.

A control system for an engine includes an engine control module (ECM) that operates in a first mode and a second mode. The ECM generates an idle speed signal and a transmission load signal that is based on an idle speed of the engine. The hybrid control module (HCM) increases electric motor torque to increase a current speed of the engine based on the idle speed signal and the transmission load signal. The HCM controls the current speed when in the first mode. The ECM controls the current speed when in the second mode. The HCM transfers control of the current speed to the ECM when at least one of the current speed matches the idle speed and a combustion torque output of the engine is equal to a requested crankshaft output torque.

An engine control system comprises a pedal torque determination module, a driver interpretation module, and an actuation module. The pedal torque determination module determines a zero pedal torque based on a desired engine torque at a zero accelerator pedal position and a minimum torque limit for an engine system. The driver interpretation module determines a driver pedal torque based on the zero pedal torque and an accelerator pedal position. The actuation module controls at least one of a throttle area, spark timing, and a fuel command based on the driver pedal torque.

An engine control module comprises a torque control module, an engine speed (RPM) control module, and an actuator module. The torque control module determines a first desired torque based on a requested torque. The RPM control module selectively determines a second desired torque based on a desired RPM. The torque control module determines the first desired torque further based on the second desired torque when the engine control module is transitioning from an RPM control mode to a torque control mode. The RPM control module determines the second desired torque further based on the first desired torque when the engine control module is transitioning from the torque control mode to the RPM control mode. The actuator module controls an actuator of an engine based on the first and second desired torques.

A minimum torque module selectively determines a first minimum propulsion torque based on second and third minimum propulsion torques when a torque converter clutch is in unlocked and locked states, respectively. A zero pedal torque module selectively sets a zero pedal torque equal to the first minimum propulsion torque. A pedal request module determines a pedal torque request based on an accelerator pedal position, a vehicle speed, and the zero pedal torque. A driver request module determines a driver axle torque request based on the pedal torque request. A shaping module selectively shapes the driver axle torque request into a shaped driver axle torque request. A conversion module converts the first minimum propulsion torque into a minimum axle torque. A final driver request module sets a final driver axle torque request equal to a greater of the shaped driver axle torque request and the minimum axle torque.

An engine control system comprises an air control module and a spark control module. The air control module controls a throttle valve based on a first desired torque when the throttle valve is in an operable state. The spark control module controls spark advance based on the first desired torque and a second desired torque when the throttle valve is in a fault state. The throttle valve is maintained in a predetermined fault position when in the fault state.
