  • Patent number: 6547694
    Abstract: A CVT has primary and secondary pulleys, and a control unit for controlling the transmission ratio by controlling the line pressure applied to the first and secondary pulleys. The control unit calculates a standard step position of a step motor corresponding to the target transmission ratio and provides a command signal representative of the difference between the standard step position and the current position of the step motor. A shift control valve actuated by the step motor controls the pressure to be applied to the primary pulley. The control unit compares the actual transmission ratio with the target transmission ratio, and if the shift is not completed, the control unit commands an additional step number. Unless the shift to the HI side is accomplished when the additional step number reaches the threshold value, the line pressure is increased to achieve the shift.

  • Patent number: 6338696
    Abstract: A lock-up controller is provided for shifting a torque converter of a vehicle from the lock-up state to the unlock state when the accelerator pedal is depressed at a speed larger than a predetermined speed when the vehicle is coasting. The controller is further functioning to prevent the torque converter from shifting to the lock-up state when the torque converter has been shifted to the unlock state and the vehicle speed is within the predetermined re-lock-up prevention speed range so as to avoid frequent lock-up/unlock operation of the torque converter.

  • Publication number: 20010023217
    Abstract: A transmission mechanism of the continuously variable transmission comprises a set of primary and secondary pulleys between which a belt is provided. The CVT control unit is operable to supply line pressure directly to a secondary pulley and also to a primary pulley via a shift control valve associated with a step motor in such a manner as to control a transmission ratio. The CVT control unit calculates a standard step position of the step motor corresponding to the target transmission ratio and provides a command signal representative of a difference between the standard step position and the current position of the step motor. The shift control valve actuated by the step motor controls the pressure to be supplied to the primary pulley. The actual transmission ratio obtained on the basis of the rotation speeds of the pulleys is compared with the target transmission ratio. If the shift is not accomplished, the CVT control unit commands additional step number.

  • Patent number: 6175785
    Abstract: A hybrid vehicle is driven by either an engine or a motor by tightening or releasing a clutch interposed between an engine and a transmission. A generator is connected to the engine, and the engine torque is absorbed by the generator when the power source is changed over from the motor to the engine. The clutch is tightened when the engine rotation speed of the motor and the engine coincide. As a result, the torque input to the transmission is maintained constant, and a shock due to change-over of the power source is suppressed.

  • Patent number: 6139472
    Abstract: A lockup control system controls a lockup state of the automatic transmission employing a torque converter with a lockup clutch. The lockup control system executes a lockup clutch engagement pressure control for decreasing an engagement differential pressure of the lockup clutch at a predetermined differential pressure for a predetermined time period under a coast lockup state. Further, the lockup control system executes a learning control for obtaining the predetermined differential pressure by adding a differential pressure correction value to a differential pressure learning value by which the torque converter generates a slight slip under the coast lockup state. Therefore, even during the coast lockup state, both of suppressing vibrations by a lowering of a lockup capacity and maintaining a responsibility for re-increasing the differential pressure are ensured.

  • Patent number: 6106433
    Abstract: A motor vehicle includes an internal combustion engine and an automatic transmission powered by the engine. The engine has a throttle valve for controlling the amount of air fed thereto. The transmission selectively assumes an Over-drive possible D-range wherein both a lock-up ON condition and a lock-up OFF condition are available and an Over-drive impossible D-range wherein only the lock-up OFF condition is kept. A control system comprises a first section for detecting a first condition of the engine wherein an open degree of the throttle valve is reduced to a certain degree; a second section for detecting a second condition of the transmission wherein the lock-up ON condition of the Over-drive possible D-range is kept; and a third section for engaging a friction element of the transmission to induce an engine brake when the first and second sections detect the first and second conditions respectively.

  • Patent number: 6074326
    Abstract: An engine-transmission drivetrain includes a torque converter situated between the engine output shaft and the transmission. The torque converter includes a lock-up clutch. A speed sensor, which measures the rotational speed of an output shaft of the transmission, generates a pulse signal. A transmission controller includes a deceleration dependent lock-up release command generator and a torque converter speed dependent lock-up release command generator. The pulse signal from the speed sensor is used as inputs to both of the lock-up release generators. In the deceleration dependent lock-up release command generator, the pulse signal is processed to derive information as to the magnitude of deceleration which the transmission output shaft is subject to. In the torque converter speed dependent lock-up release generator, the pulse signal is processed to derive information as to rotational speed of an output element of the torque converter.
