Adaptive Damper System Description - Components
Damper Unit
The adaptive damper passes the electric current that has been adjusted by the adaptive damper control unit, to the coil to operate the
valves. The solenoid valves open depending on the amount of electric current. Since the amount of oil changes depending on the
driving condition, an optimal damping force can be generated.
