Abstract
Clutch control systems for a power take-off system of a vehicle, such as those employing all-wheel and four-wheel drive systems. The control system calculates the temperature of the clutch system, based on one or more vehicle operational parameters. If the clutch system reaches a pre-determined temperature limit, the control system selectively stops the operation of the clutch system until the clutch temperature drops below the pre-determined temperature limit. The control system includes an electronic control unit, e.g., a computer or microprocessor, that calculates and/or processes one or more vehicle operational parameters, including, but not limited to: (1) clutch input and output speeds; (2) slip across the clutch; (3) clutch torque; (4) current clutch power; (5) accumulated clutch power; (6) temperature delta (i.e., change) of the clutch; and (7) clutch temperature.
