<p>A device for optically providing information pertaining to the value of the quotient of the rates of revolution of two axles contains converters connected to the axles, which converters generate electrical signals which are a measure for the rate of revolution of the respective axles. At least one of the signals is fed to a ladder network of resistances which contains tap-off points which are connected to similar inputs of comparator circuits. The other inputs of the various amplifiers receive as input the signal which is a measure for the rate of revolution of the other axle. The comparator circuits are each coupled to light-emitting elements of which a few, depending upon the the quotient of the revolution rates, illuminate. When applied in a vehicle which is provided with a continuously variable transmission, optical information pertaining to the current value of the transmission ratio is thus provided. <IMAGE></p> |
