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
Roll on Corners
DESCRIPTION OF THE PREFERRED EMBODIMENT
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 musoskelatel portion .
Example
Mercedes CL coupe
Draw-backs
Need for a large external power source
Complex control algorithms
Complex closed-loop control systems.
Requirement of fast-acting devices
Increased cost
Conclusion
In the case of active suspension
system, as in any other innovations of
automotive technology, today's innovation is
tomorrow's standard feature. Inspite 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.
