Suspension system
Suspension is the term given to the system of springs, shock absorbers and linkages that connects a vehicle to its wheels
Serve a dual purpose – contributing to the car's handling and braking.
Keeps vehicle occupants comfortable and well isolated from road noise, bumps, and vibrations,etc
Need of suspension system
Prevent the road shocks from being transmitted to the vehicle parts
To keep the vehicle stable while in motion.
Provides safe vehicle control and free of irritating vibrations and reduce wear and tear.

Functions of Active Suspension
Improves driver control, safety and stability.
Eliminates sway and reduces roll on corners
Reduces axle wrap
Maximum safety
Absorbs load, rather than resisting it, thereby ensuring a much more comfortable ride
Eliminates the need for fitting extra blades which harden the ride
Better handling and control in windy and rough road conditions
Minimize wear on tires, shocks, springs
Benefits of Bose Suspension System
Superior comfort
Superior control
Reduces body roll during turns
Reduces need for camber roll during turns
Requires only 1/3 of the power needed by the AC
Wider damping range than Magneto-Rheological systems
Applications
System high end luxury vehicles such as Lotus, Infiniti, and Mercedes-Benz
Used in F1 cars
The same technology has been applied in Military applications.
