Introduction

The vehicle suspension system is responsible for driving comfortand safety as the suspension carries the vehicle-body andtransmits all forces between body and road.

Passive suspension system consists of an energy dissipatingelement, which is the damper, and an energy-storing element,which is the spring.

Since these two elements can not add energy to the system this

kind of suspension systems are called passive.

Passive suspension systems are subject to various trade offswhen they are excited across a large frequency bandwidth.

Active or adaptive suspension is an automotive technology thatcontrols the vertical movement of the wheels via an on-board

system rather than the movement being determined entirely bythe surface on which the car is driving.

The system therefore virtually eliminates body roll and pitchvariation in many driving situations including cornering,accelerating, and braking.

The average citation frequency of the patents pertaining to this

technology is found to be 1.9866

Though Toyota has a major share of 13% patents to its name as its

average citation frequency is well below average citation frequency.

From the above graph it is clear that Ford and Nissan have good

quality patents as their average citation frequency is above average

citation frequency of all patents.

Similarly classes B60G0017018, B60G17016F, B60G170165 have

good quality patents, as their average citation frequency is more than

the average citation frequency of all relevant patents.
