Abstract

An engine control system of a vehicle comprises a torque module and a chassis request evaluation module. The torque module controls a torque output of an engine based on a driver torque request and selectively increases the torque output based on a chassis torque request. The chassis request evaluation module selectively prevents the increase of the torque output based on at least one of a vehicle speed, a transmission state, and an accelerator pedal position.
