Design and Manufacturing of Automobile
Vehicle Safety with Pneumatic Bumper - In the design of an automobile, a most important task is to minimize the occurrence and
consequences of automobile accidents. Automotive safety can be improved by "active" as well
as "passive" measures. Active safety refers to technology which assists in the prevention of a
crash. Passive safety includes all components of the vehicle that help to reduce the
aggressiveness of the crash event. Crash protection priorities vary with the speed of the car
when crash occurs.
