    Recent Trends in Automation and Automobile Engineering Volume 2 Issue 3 Introduction to Antilock Breaking System (ABS) Sager Sanjay Dawange1*, Vijay P. Satao2 1Sahakar Maharshi Late Bhaskarrao Shigne College, Khamgaon, Buldana, (MS), India 2Siddhivinayak Technical Campus, Shegaon, Buldana, (MS),India. *Corresponding Author E-Mail Id: [email protected] ABSRACT Antilock Braking System (ABS) is very useful in advanced automobiles to avoid slip and lock up of wheel when brakes applied. It is automobile protection system, the regulator is provided to regulate the required torque to sustain optimal slip ration. The slip ration signifies in terms of automobile speed and wheel spin. It is an automated system that relays on principles of threshold braking and cadence braking which were experienced by skilled drivers with former generation braking system. It reaction time is so fast to makes easy steering for the driver. ABS usually deliver advanced vehicle control and reduce the stopping distance in greasy and dry surface, on the other hand on loose surface like pebbles or snow covered pavement, ABS can knowingly rise braking distance, even though still improving vehicle control.[1].The antilock Braking System was developed by Gabriel Voisin in 1929. Keywords: ABS, Antilock breaking system, electrical control unit (ECU) antilock brakes, safety, slip factor, advance braking system, vehicle stability control INTRODUCTION ABS used to be brought in manufacturing Antilock Braking System used to unlock vehicles, such assemblies have develop as the vehicle wheel. An anti-lock braking an increasing number of state-of-the-art system (ABS) is a secure anti-skid braking and active. Modern differences may in gadget that is used on airplane and on land addition no longer only stop wheel lock transport, such as cars, motorcycles, under braking, though it may also alter the trucks, and buses.

This page intentionally left blank EXECUTIVE SUMMARY In the context of diffusion of innovation, strategic niches that emerge prior to mass-market adoption represent an important area of focus for radically new technologies, since these are typically introduced in several such subsequent niches. A niche strategy represents a response to circumvent a market situation characterized by hampered large-scale diffusion, by which a company deliberately focuses on strategic niches in the effort to either (1) develop a marketable product application or (2) market an already developed product in the existing regime, if and only if revenue can be derived from the market introduction.
