Abstract

An engine system of a vehicle includes an engine torque module. The engine torque module determines an engine output torque profile including predicted torque outputs based on an accelerator signal and an engine state variable. A load control module determines a dynamic transmission load profile based on the engine output torque profile and an engine speed profile. The dynamic transmission load profile includes transmission loads as a function of engine speed during an auto-start of an engine. A compensation module generates a torque compensation signal based on the dynamic transmission load profile. An actuator module compensates for a change in a transmission load based on the torque compensation signal and during a transition of the engine from a cranking state to an idle state.
