ABSTRACT:
Electronic device to indicate the acceleration and deceleration for vehicles; being able to be driven through means connecting to the accelerator and able to generate luminous signals which can be seen by other vehicles; characterized because, being supplied by means of a source provided with a power regulator, said device comprehends a potentiometer, that, constituting a transductor of the mechanical movement of the accelerator, is connected to a comparator circuit; said comparator circuit constituted by a plurality of operational amplifiers, each one of said operational amplifiers having a first input connected to the potentiometer, while a second input is connected to a respective terminal of a voltage divider; the output of each operational amplifier is connected to the input of a respective power amplifier which at the same time has a plurality of luminous elements connected to its output, said luminous elements constituting at least one luminous display; said display including complementary luminous elements which can be enabled in a selective way by the potentiometer in at least one of its limit positions, by means of a selective driving circuit.
