Claim 0:
1. A control system for an electrified powertrain of a battery electric vehicle (BEV), the electrified powertrain being configured to generate drive torque to propel the BEV, the control system comprising:
an accelerator pedal configured to be manipulated by a driver of the BEV between fully-off and fully-depressed positions; and
a controller in communication with the accelerator pedal and configured to control the electrified powertrain by:
determining maximum and minimum values for driver pedal position based on a first position of the accelerator pedal indicative of a first driver pedal position;
determining whether the accelerator pedal position remains to within a threshold amount of the first position;
when the accelerator pedal position does not remain within the threshold amount of the first position and moves to a second position indicative of a second driver pedal position:
detecting that driver pedal position is increasing when the second driver pedal position is greater than the minimum value and setting the maximum value to the second driver pedal position, and
detecting decreasing driver pedal position when the second driver pedal position is less than the maximum value and setting the minimum value to the second driver pedal position; and

controlling the electrified powertrain based on the accelerator pedal position and the maximum and minimum values for driver pedal position.
