Abstract
Abstract THE VELOCITY OF A VEHICLE ATTAINED DURING EACH ACCELERATION IS CONVERTED INTO A VOLTAGE AND STORED IN A CAPACITOR. UPON A DECREASE IN THE VELOCITY OR IN THE VOLTAGE, THE CAPACITOR DISCHARGES AGAINST THAT VOLTAGE TO BRING SWITCHING TRANSISTORS INTO OPERATION SO THAT THE DECELERATION OF THE VEHICLE MAY BE INDICATED. THE DECELERATION CAN BE IN- DICATED EITHER INDEPENDENTLY OF THE VELOCITY OF THE VEHICLE OR AT VELOCITIES ABOVE A PREDETERMINED VALUE.
