■Operation at input speed deceleration during slippage method smoothing
When the speed before clutch processing decreases, the speed after clutch smoothing is controlled without exceeding the
speed before clutch processing.
If slippage amount remains when the speed before clutch processing becomes 0, the smoothing process will be continued.
Then, the clutch smoothing process will be executed with the remaining slippage amount when the speed before clutch
processing gets faster than the speed after clutch smoothing.
