Main Functions

Vehicle sensors monitor road bumps, driving speed and body posture, and send real-time signals to the electronic control unit. The built-in inductive coil generates magnetic force when electrified to adjust hydraulic flow resistance. Damping stiffness rises with increased current and falls with reduced current. As road shocks push the piston, regulated oil flow efficiently absorbs vibration and restricts body sway. The system switches working modes intelligently: softer damping ensures comfort during low-speed travel, while firmer damping boosts driving stability when speeding up, cornering or braking.
