Abstract
A vehicle has an engine having a crankshaft, a hydraulically controlled multi-plate clutch operatively connected to the crankshaft, and an output shaft operatively connected to the clutch. The clutch selectively transmits power from the crankshaft to the output shaft. A propulsion element is operatively connected to the output shaft. A hydraulic fluid supply system is fluidly connected to the clutch for supplying pressurized hydraulic fluid to the clutch. A controller is connected to the hydraulic fluid supply system. The controller receives a torque signal indicative of engine torque and controls the hydraulic fluid supply system based at least in part on the torque signal. A clutch control method and system are also disclosed.
