The improvements comprise the incorporation in the signalling system of a speed sensor (1), of any type, which measures continuously the instantaneous speed value and which provides also permanently the appropriate signals to a deceleration discriminator (2) provided with minimal speed and deceleration thresholds adjustable by means of corresponding controls (3 and 4) and, in case of exceeding said thresholds, an output signal (5) is generated in order to close a complementary optical brake signalling circuit, such as for example the winking light circuit of the vehicle, the stop light circuit or any other circuit, an emergency signal being generated when the deceleration is due to a sudden braking. A switch (7) allows to override said auxiliary circuit or to provide a manual or automatic operation for said auxiliary circuit. |
