    摘要： An engine control system of a vehicle comprises a reserves module and a fault diagnostic module. The reserves module controls airflow into an engine based on a driver torque request, increases the airflow into the engine when a reserve torque request is received, and outputs a torque output command for the engine based on the driver torque request. The fault diagnostic module selectively diagnoses a fault in the reserves module when the torque output command is greater than a sum of the driver torque request, a predetermined torque, and a load applied to the engine.

    摘要： A method and control module for controlling an engine includes a requested torque module that generates a requested torque and a maximum toque capacity module that determines a maximum torque capacity corresponding to a maximum torque capacity of the engine. A launch trim torque threshold determination module determines a launch trim torque threshold. A comparison module that compares the requested torque and the launch trim torque threshold. An output module that applies a fast rate limit to the requested torque up to the launch trim threshold when the requested torque is less than the launch trim torque threshold and a shower rate limited torque request when the requested torque is greater than the launch trim torque threshold.
