Method and system for controlling torque during a vehicle launch condition |
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.
