Electronic Damping Control (EDC) (BMW 5 Series E39)

The electronic shock absorber stiffness monitoring system (EDC), which is installed as an additional equipment, matches the stiffness of shock absorbers with changing road conditions almost without inertia.

The sensors constantly monitor such parameters as the speed of movement, vertical acceleration of the body, pressure in the brake system, vehicle load, steering angle of the steering wheels and the position of the accelerator pedal. Based on the signals from the sensors, the computer generates control commands, according to which the electromagnetic valves change the shock absorber shock absorber damping force from hard to medium or weak.
