1. A vehicular machine manual gearshift and clutch training apparatus including sensory indicator means providing admonition for the most favorable operator control thereof, comprising in combination:

  • a. An operator controlled vehicular machine apparatus consisting of at least;

    A driving engine means, including an output means therefrom;

    A clutch means including an input coupled to said driving means output, wherein said clutch means provides, at an output therefrom, at least a state of engagement and a state of disengagement of said output from said input by means under the control of an operator;

    A transmission gearing means including an input coupled to said clutch means output, wherein said transmission means provides, at an output therefrom, at least two combinations of gearing together with a means for operably selecting therebetwixt by means under the control of the operator;

    Propulsion means coupled to said transmission means output, wherein said propulsion means is operative to enable the mobility of the said vehicular machine;

    b. A speed sensing means coupled to said driving engine means operative to provide a bounding signal pattern output therefrom, wherein the definition of such signal is constrained by the pre-established best operational performance range of the said driving engine means;

    c. A transmission gear combination sensing means operative to provide a unique signal pattern output therefrom for each available combination of transmission gearing ratios;

    d. A clutch sensing means operative to provide a unique signal pattern output therefrom for at least one condition of engagement, partial engagement, and disengagement of the said clutch means;

    e. A processing logic unit means including a plurality of inputs thereto which are operatively connected to the said speed sensing signal output, said transmission gear combination sensing signal output, and said clutch sensing signal output wherein said logic unit is operative to provide at least one derived conditional output signal therefrom the logic combination of which is dependent upon the particular pattern of input signals provided thereto by the said sensing means;

    f. A first sensory indicant means operative by at least one signal derived from the said processing logic unit output to provide for the operator an indication of the correct gearing combination which should be engaged;

    g. A second sensory indicant means operative by at least one signal derived from the said processing logic unit output to provide for the operator a distinctive indication of the impending need for gearing readjustment;

    h. A third sensory indicant means operative by at least one signal derived from the said processing logic unit output to provide for the operator a distinctive indication of the abusive operation of the clutch means.
