Electronic control by rigidity of shock-absorbers (EDC)

The system of electronic control by rigidity of shock-absorbers (EDC) delivered as an additional complete set practically without delay adapts rigidity of the shock-absorber to variable conditions of the road and the movement.

All changes of speed, vertical acceleration of a body, pressure of braking, loading of the car, angle of rotation of a steering wheel and position of the accelerator pedal are constantly controlled by sensors. On the basis of the obtained data the computer develops the corresponding signals of control of shock-absorbers which rigidity is regulated by electromagnetic valves and is installed in the mode "rigidly", "average rigidity" or is "soft".
