    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： An automatic clutch control system and method for controlling a clutch for an automatic transmission when a clutch stroke sensor fails. The apparatus includes 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 when requests for clutch engagement or disengagement are received and for controlling the solenoid valves so as to obtain a clutch moving speed defined by an engine rotational speed and other driving conditions. The control unit further includes a clutch engagement control section and a clutch disengagement control section for controlling solenoid valves for operating the clutch independently of the stroke signal when the stroke sensor fails. The control unit detects a failure of the stroke sensor by defining an upper limit value and a lower limit value for the stroke signal and when the stroke signal exceeds the upper limit value or is lower than the lower limit value it is determined that the stroke sensor has failed. The method includes the steps of setting the upper and lower limit values for the stroke signal, detecting a clutch stroke sensor failure by determining if the value of the stroke signal exceeds the upper limit or is less than the lower limit and operating the clutch at a predetermined speed if a stroke sensor failure is detected.

    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： Herein disclosed is a signal processing system for a motor vehicle with high responsiveness to the will of a driver. The output voltage of an acceleration sensor using a potentiometer is converted into a digital value by an analog-digital converter. The nonlinearity of the output voltage is corrected by polynominally calculating the digital value. This digital value is controlled by a central processing unit which processes the digital value to generate an acceleration signal having a linear relationship to the changes in the resistance of the potentiometer during actuation of an accelerator. The central processing unit further includes a memory for storing the acceleration signal at an idling position to determine a calibrated acceleration signal using a ratio of an actual acceleration signal obtained from the accelerator pedal to the stored value thereof.
