Clutch Control block diagram
Role of subsystem in vehicle
The clutch control determines whether the clutch should be fully engaged, fully disengaged, or slipping–transmitting torque while the two sides of the clutch spin at different speeds.
Description of modeling approach
The state of the clutch depends on the requirements of the drivetrain.
then the clutch is disengaged.
then the clutch is slipping (meaning that the engine is required to operate at its launch speed).
If the clutch is neither disengaged nor slipping, then it is engaged.
If the clutch is being used in a parallel hybrid and the engine is off, the clutch is disengaged regardless of the above conditions.
