Abstract
An engine control system includes an air control module, a spark control module, and a reserves module. The air control module controls a throttle valve of an engine based on an adjusted predicted torque request. The spark control module controls spark timing of the engine based on an adjusted immediate torque request. The reserves module determines an arbitrated reserve based on a maximum one of a minimum reserve and an additive reserve sum. The reserves module also generates the adjusted predicted torque request based on a sum of an arbitrated predicted torque request and a requested reserve, wherein the requested reserve is based on the arbitrated reserve.
