    摘要: 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 singal (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 inputs thereto.

    摘要: In a free-wheeling vehicle drive system in which the free-wheeling function is cut in and cut out entirely in response to normal driving operation of acceleration and deceleration, at least the signal corresponding to engine acceleration, which may be provided by the accelerator pedal, is subjected to delay before it may set a flipflop establishing the free-wheeling function. The braking signal, which may conveniently be derived from the brake-light switch, can likewise be advantageously delayed in its resetting of the flipflop in order that brief touching of the brakes should not disable free-wheeling. A more refined system which cuts in free-wheeling only after acceleration of the engine followed by the establishment of an idling condition of the engine can be used without the necessity of providing an overrunning clutch, since the control of a normal clutch connecting or separating engine and drive train can provide free-wheeling. The use of both slow-acting engagement of the clutch and an overriding fast-action engagement, and the taking account of engine speed, engine temperature, downward road slope and rapid changes of position of the accelerator pedal, can provide a sophisticated and nevertheless natural control of free-wheeling over a wide variety of driving conditions.
