  make min-speed for downshift polygon a parameter
  allow reading pev shift parameters from file
  finetuning PEV shift strategy
  refactoring PEV shift strategy: simplify required methods, prohibit eff-gearshift when at max recuperation, prevent gearshift on drive-off (until target speed reached, em-speed above n_P80low, or operating point at full-load)
  implementing first idea of shift polygons for PEV
