Abstract

An input control system, method, and apparatus for adjusting an input control value of a motor or engine by damping the acceleration curve. In certain aspects, the damping may gradually increase until the input control optimization system detects a change in the behavior of the vehicle operator, for example, in the form of a conscious or unconscious increase in aggressive use of the accelerator pedal. When such behavior is detected, the input control optimization system reverses the damping and begins to restore gradually the original acceleration curve until aggressive pedal use by the operator is no longer detected.
