10. Functions of Active Suspension
Improves driver control, safety and stability, with or without a
load .
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, shackles and leaf springs
13. Active suspension mimics the
functions of the human body
The sensors are nerve ends
The Electronic Control Unit represents our mind
Wires connecting the whole thing are the central
nervous system
The servos and actuators resemble the muso-
skelatel portion .
16. ADVANTAGES
•Stabilizes the wheel independently.
•Increases the overall grip of the vehicle, hence
creating a safer ride.
•It has soft spring which improves ride quality and
passenger comfort.
•Eliminates body role during high speed cornering.
•Anti role bar is omitted.
•Ride height is not affected by varying static load.
17. Draw-backs
Need for a large external power source
Complex control algorithms
Complex closed-loop control systems.
Requirement of fast-acting devices
Increased cost
18. Conclusion
In the case of active suspension system, as in any
other innovations of automotive technology, today's
innovation is tomorrow's standard feature. In spite of its
high initial cost, let us expect to see them in the Indian
roads soon. The trickle-down effect will take some time, but
it'll happen and when such a time comes we can expect
much lesser accidents, less fatalities and more comfort in
driving the roads.
