Automatic pressure maintenance system for tyres in automobiles to reduce accidents

One of the important factors that play key role in increasing automobile efficiency and reducing number of road accidents, is optimum tyre pressure maintenance. Variation of tyre pressure from the optimum value can result in reduction of fuel mileage, tyre life, and safety and often in tyre bursts causing accidents. We propose the design of an automatic system that can ensure and maintain tyre pressure to its optimum safe value. The design consists of real time tyre pressure monitoring system for taking periodic pressure readings, a pressure control system that makes adjustments to achieve the desired pressure settings and a wireless communication link to integrate both these systems together. The design in addition allows adjustments to predefined terrain based tyre pressure settings and to manually entered pressure settings. The implementation, testing, and analysis of the system is provided in this research work.
