Abstract: An adaptive braking system for a set of vehicle wheels, of the type comprising a fluid pressure source, braking apparatus associated with the set of wheels, and control apparatus for controlling the fluid pressure acting on the braking apparatus. The fluid pressure supplied to the braking apparatus is automatically controlled by the control apparatus in successive stages of pressure increase and pressure decrease separated from one another by intervals during which the pressure is kept constant. More particulary, a stage of pressure increase is controlled after an interval whenever the deceleration of a wheel has been decreasing or has remained constant during this interval, and a stage of pressure decrease whenever the deceleration has been increasing during the interval.

Abstract: The invention relates to an electronic anti-skid system which avoids the untimely operating of the system which occurs especially further to the aleatory variations of the wheel speed. A given percentage of the output voltage of a wheel speed sensor is memorized in a capacitor by means of a diode, as soon as the wheel decelerates. The exhaust signal which is given at the output of an anti-skid logic circuitry is transmitted to a transistor only when the wheel speed has decreased of an amount equal to the complementary percentage of the given percentage. The resetting of the devices is effected by another diode which deletes the memorized voltage of the capacitor.

Abstract: An electronic antiskid braking system of the type using a speed reference signal having a maximum rate of decrease as established, furnished by the constant current discharge of a capacitor in a circuit, is disclosed. The maximum slippage which is tolerated by the wheel includes a constant quantity which is determined by a potentiometer, and includes too a variable quantity, which is obtained from the direct voltage-drop in a diode. A switching device controlled by the first occuring pressure reducing signal of an antiskid braking operation, is provided to modify the intervention threshold during the initial adaptive braking cycle.

Abstract: A voltage converter set designed to feed an antiskid logic element and to modify the wheel speed sensor signals. The converter set includes a proportional converter and an inversely proportional converter, connected through a diode, so that the output voltage of the converter set is higher for the low wheel speeds. The invention also provides the combination of several converter sets with a single antiskid logic element in a circuit of the exclusive ''''OR'''' or ''''SELECT LOW'''' type.
