Abstract
A control module includes a predicted torque control module that determines a desired throttle area based on a transmission torque request and a desired predicted torque. A throttle security module determines a throttle limit based on the desired throttle area and the desired predicted torque and determines an adjusted desired throttle area based on the throttle limit. A throttle actuator module adjusts a throttle based on the adjusted desired throttle area.
