It is important to study the deceleration inside passenger compartment to know the effect of crash completely, so that the crash avoidance systems can be suitably designed. For example, if the deceleration of the passenger after crash is very high, the air bag system and the seat belt system has to be so designed that the activation time for them is reduced to a lower value. Otherwise it may lead to injuries and fatalities.

Usually tests are conducted to know the deceleration behavior after the crash with a stationary obstacle. The tests are conducted at the following speeds:

15 mph (miles per hour)

20 mph

40 mph

50 mph

15 mph test:

The following pictures show the body deformation and acceleration graph after crash. The body deformation is less as the vehicle speed is low. The crash occurs at time 0 seconds. From the graph, we can know that after the crash, deceleration occurs which is shown in the negative (lower) portion. Its value is up to 20g. After some time the acceleration slowly comes to zero (the car stops).

This book has been written for the Medical/Pharmacy/Nursing/ME/M.TECH/BE/B.Tech students of All University with latest syllabus for ECE, EEE, CSE, IT, Mechanical, Bio Medical, Bio Tech, BCA, MCA and All B.Sc Department Students.

The basic aim of this book is to provide a basic knowledge in Automotive Safety.

Automotive Safety Syllabus students of degree, diploma & AMIE courses and a useful reference for these preparing for competitive examinations.

All the concepts are explained in a simple, clear and complete manner to achieve progressive learning.

This book is divided into five chapters. Each chapter is well supported with the necessary illustration practical examples.
