    摘要: An automatic clutch control system, for use in automobiles, using a microcomputer. Included in the system are an accelerator pedal sensor for detecting accelerator position; an engine speed sensor for detecting engine speed; a clutch stroke sensor for detecting clutch stroke; and an automobile speed sensor for detecting automobile speed. The microcomputer is included in a controller for controlling opening or closing of solenoid valves, gear change of a transmission, and opening or closing of a throttle actuator, based on predetermined stored data and based on signals transmitted from the sensors. The automatic clutch control system consequently can automatically control the clutch moving time and clutch moving speed for easy driving under all driving conditions. Moreover, while the clutch control system is fully automatic, it can use dry-type single-plate clutches and sliding-mesh-type transmissions as in manual and semiautomatic transmissions.

    摘要: A method of controlling a shifting operation of a synchro mesh type automatic transmission in a vehicle, such as an automobile. The method includes the steps of (i) detecting the running state of the vehicle, (ii) determining an optimum gear position from the vehicle running condition, (iii) determining if the optimum gear position is higher than a gear position of the transmission, (iv) determining if the engine torque is greater than or equal to a predetermined value and reducing the engine torque below the predetermined value, if the optimum gear position is higher than the gear position of the transmission, (v) disengaging a clutch to disconnect an engine and the transmission, (vi) shifting the transmission to the optimum gear position, and (vii) engaging the clutch. Moreover, the engine torque is reduced before the clutch is released--by reducing the fuel supply to the engine--so that abrupt decelerations and declutching shocks caused by conventional shifting methods are not felt by the driver.

    摘要: An automatic clutch control system including a clutch, a clutch actuator for controlling a clutch stroke, a plurality of solenoid valves for controlling the clutch actuator, a clutch stroke sensor for measuring the clutch stroke, a control unit for feeding back a stroke signal detected by the clutch stroke sensor and for controlling the solenoid valves to control clutch engagement and disengagement. The control unit includes a learning control section for storing a full clutch engagement point upon saturation of the stroke signal in a clutch engagement operation and storing clutch contact point upon start of rotation of an engine input shaft in a clutch engagement operation following a clutch disengagement operation. Based on the full clutch engagement point and clutch contact point, the control unit judges a clutch operation range for control of clutch engagement and disengagement.

    摘要: A method of controlling the starting of a vehicle having an engine, an automatic clutch and an electronic control system which detects the extent of depression of an accelerator pedal and determines the speed of operation of a clutch actuator based on the detected extent of depression of the accelerator pedal. In particular, the method includes detecting a load on the engine due to a change in the condition in which the clutch is engaged, and stopping connection control of the clutch when the detected load on the engine is increased, to prevent an engine stop. In addition correction is made to vary the speed at which the vehicle starts linearly with respect to the extent of depression of the accelerator pedal.

    摘要: A vehicle transmission system has an internal lever for changing transmission gears, a select actuator for moving the internal lever to neutral positions N1, N2, N3 in a first direction, a shift actuator for moving the internal lever to 1st-5th gear positions and a reverse position in a second direction substantially normal to the first direction, and a clutch actuator for actuating a clutch. While any one of the actuators is in operation, the pressure of a fluid discharged from the operating actuator is prevented from acting on the select actuator and/or the shift actuator which is not in operation by applying a fluid pressure to the inoperative select actuator and/or the shift actuator to fix the actuator or actuators in a current position against operation, thereby allowing the transmission gears to be changed accurately and smoothly.
