Abstract
A control system includes a driver torque determination module, a lash zone torque determination module, a rate limit determination module, and an immediate torque determination module. The driver torque determination module determines a driver torque request when a driver depresses an accelerator pedal while a vehicle is coasting. The lash zone torque determination module determines a lash zone torque based on a transmission gear and an engine speed. The rate limit determination module determines an adjustment rate limit based on a previous immediate torque request, the lash zone torque, and the transmission gear. The immediate torque determination module determines a present immediate torque request based on the driver torque request and selectively determines the present immediate torque request based on the adjustment rate limit.
