    Abstract: A transmission system for a straddle vehicle which provides two operating modes, namely semi-automatic and automatic. With the semi-automatic transmission system, an operator only uses a switching means mounted on a sheeting bar of the vehicle for activating a clutch actuator and a shift actuator. The clutch actuator disengages a transmission clutch while the shift actuator operates a shifter for changing the transmission ratio. With the automatic transmission system, an Electronic Control Unit reads inputs signals such as speed of the engine (RPM), speed of the vehicle, opening of a throttle valve and position of a shifter and accomplishes a smooth shifting by activating a clutch actuator, a shift actuator and a modulated controlling valve.

    Abstract: A device and a method of a hydraulic control system for 4-speeds automatic transmissions which may reduce line pressure in a steady flow during operation of an automotive vehicle at high speed thereby decreasing the load applied to an oil pump and reducing fuel consumption. And when shifting from the second, third or fourth speed of the "D" range, where the damper clutch operates, to another shift range, which makes it so the line pressure is not changed when the damper clutch is released thereby increasing the load applied to the engine, thereby preventing the run-up of the engine, and when the shift is completed, which changes the line pressure again, thereby improving shift quality and power transmission efficiency.

    Abstract: A lock-up clutch of an automatic transmission is controlled by an electronic control unit using a gear shift diagram and a lock-up clutch changeover diagram each having vehicle velocity plotted along identical abscissa and throttle opening plotted along identical ordinate. Changeover of the lock-up clutch is controlled upon setting a changeover line in the changeover diagram in accordance with which the lock-up clutch is changed over from OFF to ON state, and changeover of transmission gear ranges is controlled upon setting a transmission gear range changeover point in the gear shift diagram. The changeover line is set in such a manner that it will not intersect a region in the gear shift diagram where the shift position is 2nd gear range or less and the throttle opening is less than a predetermined value. Thus, the lock-up clutch is not engaged in a case where the transmission is in 2nd gear range or less and, moreover, the throttle opening is less than a predetermined value.

    Abstract: A vehicle transmission includes a gear transmission mechanism and a torque converter with a lock up clutch, both hydraulically activated. The transmission control device practices the method, and includes an electronic computer which inputs data representing operational parameters of the vehicle and outputs transmission speed stage command signals and lock up clutch command signals, and a hydraulic control system controlled by the computer which according to these signals controls the lock up clutch to be engaged or disengaged and the transmission to be set to its various speed stages. Sometimes the lock up clutch is engaged just before the computer changes the speed stage of the transmission, and in this case the lock up clutch is disengaged by the computer during a time period overlapping the time period taken for the change of speed stage, with the time instant of commencement of dispatch of lock up clutch disengage signals from the computer to initiate the disengagement of the lock up clutch being displaced in time from the time instant of dispatch of speed stage change signals from the computer to initiate the change of speed stage. Particularly, the time displacement may be forward in the case of an upshift, and backward in the case of a downshift.
