Abstract

A system according the principles of the present disclosure includes a torque determination module and a torque limit module. The torque determination module determines a first torque that prevents an engine from stalling. The torque limit module limits engine torque based on the first torque when a driver actuates an accelerator pedal from a first position in which the accelerator pedal is not depressed to a second position in which the accelerator pedal is depressed.
