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 a delay adapts rigidity of the shock-absorber for variable conditions of road and 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 a pedal of gas are constantly supervised by gauges. On the basis of the received data the computer develops corresponding signals of management of the shock-absorbers which rigidity is regulated by electromagnetic valves and is established in a mode "rigidly", “average rigidity” or is soft".
