Ok, consider this project:
  • Honda IMA with manual transmission.
  • Let the IMA control the ICE shaft speed to match either up-shift or down-shift requirements.
  • Solenoid actuators to shift the gears.
You might still need the clutch to handle take-off from a dead start or up a hill. But once moving, everything else could be automatic with no further clutch plate wear. This is not an original idea I came up with but something I remember reading about in the past six years.
