Title: Slip based throttle progression modifier

Abstract: A control system for adjusting a throttle progression curve to compensate for traction slip calculates a maximum vehicle acceleration value based on wheel torque and vehicle speed conditions, then compares the actual vehicle acceleration to determine if it is greater than the maximum acceleration to determine if slip is detected, and adjust a throttle progression curve based on the results of the comparing step to enable the vehicle to learn the current road conditions and reduce the throttle progression for a given pedal position during slippery conditions to reduce the amount of slip that occurs during future accelerations.
