摘要: A shift control for an automatic countershaft type transmission includes a memory device which stores a plurality of maps representing optimum speed ratios for various vehicle conditions. The control selects from the maps based on the speed of the vehicle, the position of the accelerator pedal and on the state of operation of a brake. The control further determines whether the position of a shift lever corresponds to the optimum gear ratio obtained from the selected map. The transmission is shifted to the optimum gear ratio when the shift lever doesn't correspond to the optimum gear ratio position.

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.

摘要: A torque transmission device for eliminating the transmission of tortional vibration from a driving shaft to a driven shaft comprises a clutch capable of controlled slippage so that the speed of rotation of the driven shaft is lower than the speed of the driving shaft. Slippage of the clutch is controlled by sensing the speed of rotation and the fluctuation of the speed of rotating of the driving shaft and the speed of rotation of the driven shaft and regulating slippage so that the difference in rotation speed between the two shafts is greater than the fluctuation in rotation speed of the driving shaft. The clutch may be an electromagnetic clutch of which the exciting current is controlled or a friction clutch actuated by controlled hydraulic pressure. The clutch may be in parallel with a fluid coupling.

摘要: A system for controlling an electromagnetic clutch of an internal combustion engine mounted on a vehicle, in accordance with the engine speed and vehicle speed. The electro-magnetic clutch has a drive member secured to a crankshaft of the internal combustion engine, a magnetizing coil provided in the drive member, and a driven member adjacent said drive member. A shift lever switch produces a signal during the operation of a shift lever for the transmission. A speed sensor detects the speed of said vehicle producing a signal when the speed exceeds a predetermined value, and a clutch hold switch produces a signal when the speed of the engine exceeds a predetermined value. Both signals are fed to a control circuit. The control circuit maintains current through the magnetizing coil when the speed sensor and the clutch hold switch produce respective output signals.

摘要: An automatic clutch system is provided for use in a motor vehicle and has a control mechanism which responds to the position of the accelerator pedal and which also responds to first and second rotation speed sensing means connected to the engine shaft and the transmission shaft. In a preferred embodiment, the automatic clutch system is provided with a control mechanism which operates in a first mode when the vehicle is starting from a standing position to engage the clutch in a manner which keeps the engine in a specified speed range, which depends on accelerator lever position. The control mechanism operates in a second mode when the vehicle is shifted between gears in order to engage the clutch in a manner which provides a constant time gradient for the shaft speed difference selected in accordance with accelerator pedal position.

摘要: A power transmission that includes hydraulically-operated clutches that areelectively supplied with operating fluids by a selector valve that is controlled by an error signal means constructed to compare prime mover speed and user demand speed. The transmission preferably is a split torque hydromechanical transmission having one power path going through a hydrostatic pump-motor unit and another path going only through epicycloidal gearing system containing the hydraulically-operated clutches. The transmission is controlled hydraulically rather than mechanically, thereby avoiding problems relating to mechanical slack, response lag, and reliability.
