Active suspension control: – Comfort and safety : maintain chassis stability and vehicle height constant. – Safety and fun to drive : adapt suspension performances to road and drive conditions, and allow the driver to select modes (sport, comfort). Load monitoring: – For safety purpose the system monitor the vehicle load and balancing.
