Abstract:
1. A control system, comprising: a driver torque determination module that determines a driver torque request when a driver depresses an accelerator pedal while a vehicle is coasting; a lash zone torque determination module that determines a lash zone torque based on a transmission gear and an engine speed; a rate limit determination module that determines an adjustment rate limit based on a previous immediate torque request, the lash zone torque, and the transmission gear; and an immediate torque determination module that determines a present immediate torque request based on the driver torque request and that determines the present immediate torque request based on the adjustment rate limit when a difference between the previous immediate torque request and the lash zone torque is less than a torque threshold; and an actuation module that controls an actuator of an engine based on the present immediate torque request.
