| description | A closed loop clutch pressure control effective during steady state (nonshifting) operation of a motor vehicle transmission for adjusting the scheduled clutch pressure to generate torque capacity substantially in the amount required to transmit the transmission input torque. When significant slippage is detected, the pressure is adjusted upward to increase the torque capacity of the clutch. If significant slippage is not detected over a period of specified driving cycles, the pressure is adjusted downward to decrease the torque capacity of the clutch. This results in a low frequency clutch pressure limit cycle which enhances the efficiency of the transmission control while maintaining the clutch slippage within acceptable limits. |
