Technical Examples

A system for reducing clunk in a driveline of a vehicle having an engine comprises a torque-based module that generates a torque request, a filter that receives the torque request from the torque-based module and that selectively modifies the torque request to reduce a rate of change of the torque request, and an engine control module that receives the modified torque request and actuates the engine to produce the modified torque request. The filter slows torque changes to a fixed rate within a range defined by an upper limit greater than zero torque and a lower limit less than zero torque. The filter applies a low-pass filter to the torque request when the torque request is greater than a cut-off value, and coefficients of the low-pass filter are selected from a table based upon the currently selected gear in the vehicle and an output of an aggressive driving evaluator.
