SUSPENSION CONTROL UNIT

Specifically designed to implement a patented e-Shock solution to optimally manage the damping in two, three, and four wheeled vehicles.

The device handles the inputs from external sensors used to monitor the vehicle attitude, the chassis and suspensions dynamics, and the driver manoeuvres. Thanks to this set of information, processed by e-Shock algorithms, the device drives up to 8 electro-hydraulic valves or 4 magnetorheological dampers.
