摘要： An automatic gear shifting device for operating a gear-shift type transmission in conjunction with a disc type clutch of an automobile, comprising: a control unit; a trigger switch operable by the accelerator pedal of the automobile; detectors for detecting engine speed, automobile road speed, transmission position (gear position) and clutch position and for delivering control signals to the control unit; actuators operable by vacuum produced in the intake manifold of the engine or by a pressurized air or fluid to operate the clutch and the transmission, the actuators each having a solenoid valve through which the vacuum or the pressurized air is applied to the actuator; the control unit, upon receiving and processing the control signals, being adapted to deliver operation signals to the solenoid valves to allow vacuum or pressurized air or fluid to be applied to the actuators in a pre-programmed sequential order to operate automatically the transmission and clutch to adjust to the speed and load condition of the automobile. The device of this invention further comprises a mode selection switch for selectively changing the function of the device from automatic operation to manual operation, so that the transmission may be manually operated if so desired.
