Abstract

A hydraulic vehicle clutch system and preemptive control method includes a hydraulic vehicle clutch, a vehicle speed sensing device, a shift position sensing device, and a hydraulic pressure generating system. The pressure generating system sends hydraulic fluid to the clutch at a first pressure when (1) the vehicle speed sensing device indicates that the vehicle speed is at or below a threshold vehicle speed and (2) the shift position sensing device indicates that the shift position is in a nondrive position and at a second, higher pressure when (1) the vehicle speed sensing device indicates that the vehicle speed is at or below the threshold vehicle speed and (2) the shift position sensing device indicates that the shift position is in a drive position.
