In a Tesla data log readout, what does an accelerator pedal reading of 0% signify? Does an accelerator pedal reading of 0% mean that the pedal is released and that zero motor torque is being produced, like it does in an ICE vehicle? Or, considering that the Tesla accelerator pedal is used for one-pedal driving, does an accelerator pedal of 0% imply that the accelerator pedal is released and that the vehicle is in maximum regen mode with negative motor torque being produced?
At zero vehicle speed, this might not make much of a difference because at zero vehicle speed both forward torque and regen torque are zero at 0% accelerator pedal. But at nonzero vehicle speeds, with one-pedal driving the accelerator pedal sweet spot that indicates the boundary between forward acceleration and regeneration increases with vehicle speed. Therefore, at nonzero vehicle speeds the accelerator pedal reading at which positive motor torque begins to be produced increases with vehicle speed. This means that at nonzero vehicle speeds a given accelerator pedal percentage reading may indicate different values of torque in percentage of maximum torque, or even different values of negative torque. And at all non-zero forward speeds, a 0% accelerator pedal reading will always indicate a maximum regen torque (i.e., negative torque) that varies with vehicle speed.
So, can someone please explain to me the mapping between percent accelerator pedal depression and percent maximum motor torque that applies in a Tesla data log readout? At what accelerator pedal percentage reading does positive torque begin to be applied to cause forward vehicle acceleration? Is this data log mapping the same as the EDR readout mapping?
