    摘要： A remote control system for an automotive transmission in an earth-moving vehicle which includes a fluidic variable frequency oscillator having a variable feedback loop controlled by a quadrant lever which acts as a gear shift control. When the lever is moved between spaced transmission control positions, the frequency of the signal at the output is swept through the frequencies corresponding to intermediate control positions. The waveform of the output signal is non-symmetrical having a fixed "off" time and an "on" time which varies in length as an inverse function of the frequency. The output signal is fed to a fluidic transmitter, then through a pair of conduits to a fluidic receiver. The "on" output port of the receiver feeds into a manifold developing pressure therein which varies with the degree of dissymmetry of the wave, that is, inversely with frequency. A plurality of Schmitt triggers have their control ports connected to the manifold and have reference ports progressively biased so that pressure is produced at their output ports in succession. A power actuator of the progressive indexing type is connected to the Schmitt trigger output ports and is mechanically coupled to the gear shift member of the transmission to provide smooth transition through the gears regardless of the magnitude of the change in gear ratio. The lowest gear is interlocked with engine speed to prevent going into this gear when the engine speed is too high. The reverse gear is effectively interlocked with a forward motion detector to insure that the vehicle is at standstill before the transmission may shift into reverse.
