Abstract:
     A transmission control equipment contains: a speed sensor used to detect the rotating rate of spindle; a number of speed sensors used to detect the rotating rates of speed-changing gears; a number of actuators used to achieve speed-changing conversion; and a number of displacement sensors used to detect the displacement of clutch gears; and the transmission control equipment depending on the output signal of speed sensor controls the actuators. Within the equipment, from the beginning of speed-changing, after a predetermined duration, if the finished signal of speed-changing is not detected yet, a clutch gear, which is connected to selected speed-changing gear, returns automaticly to idle position.
