Abstract: Over 1,46,000 people were killed in road accident in India in 2015 alone. To reduce road accidents, government is keep on implementing rules and speed regulations. To control the top speed of commercial vehicles, government installs a device termed Speed Limiting Governors. Various Researches and development are done each and every day to ensure road safety. To Ensure road safety a system termed “Global Positioning and Braking System (GPBS)” can be used. The ultimate aim of this system is to control the speed of the vehicle under different conditions. Global Positioning and Braking System is integrated with the Electronic Control Unit (ECU) of the vehicle. ECU and GPBS senses the position and angle at which the vehicle traveling with the help of onboard devices. This Global Positioning and Braking System provides an interface between the satellite and ECU. Onboard devices consists of Positioning chip and Clinometers. Positioning chip interacts with the satellite and sends the position of vehicle to GPBS. Clinometers incorporated with spirit level is used to sense the tapering angle of the steep at which the vehicle currently travels. All data from onboard devices is transmitted to Electronic Control Unit through Global Positioning and Braking System. Electronic Control Unit controls the Braking system and Fuel injector based on the received data with the help of preset program in it. Braking system is used to gradually reduce the speed of vehicle. Control over Fuel injector is done to control the power output of the engine. In a automotive, the power output is directly proportional to the speed of the vehicle. This entire system can replace Speed limiting governors which is currently used in commercial vehicles alone. GPBS can be used in all types of automotives. This system greatly ensures the road safety and reduces the road accident to greater extent.
