ABSTRACT OF THE DISCLOSURE An automatic clutch control system for controlling a vehicle master clutch (14) drivingly interposed a throttle controlled engine (12) and a change gear transmission (10) having a clutch protection portion (70) to prevent the clutch from destructively overheating due to excessive slipping is provided. The clutch protection portion (70) includes a device for maintaining a variable parameter simulating clutch operating temperature (110) and devices (104 and 116) for causing said variable parameter to be increased and decreased, respectively, at first and second rates selected to simulate clutch heating and cooling rates, respectively. A signal generating device (126) is responsive to the simulated value exceeding a predetermined limit to generate a clutch protection output signal (84) effective to cause the clutch to be operated in a non-slipping, preferably fully engaged, mode of operation. The devices (104 and 116) for causing the numerical value to be increased or decreased are actuated in response to sensed and/or calculated inputs (72, 74, 76, 78 and 82). The device (126) for generating the clutch protection signal may be reset to a non-signal generating condition in response to selected sensed and/or calculated imputs thereto.
