Description:A SYSTEM AND METHOD FOR TIRE INFLATION AND DEFLATION
FIELD
[0001] The embodiments herein generally relate to tire inflation and deflation. More particularly, the disclosure relates to a system and method for faster tire inflation and deflation.
BACKGROUND AND PRIOR ART
[0002] Central tire inflation systems (CTIS) are provided in vehicles for controlling air pressure in each of the tires thereby improving performance on different surfaces. The central tire inflation system (CTIS) includes components for measuring pressure of each of the tires and inflating the tires of the automobile.
[0003] Adequate tire pressure is very crucial for safety and maintaining performance of the automobile. Tire pressure impacts responsive steering and handling, and affects braking distances. The rate of wear of the tire is also directly dependent on the tire pressure. Hence, it is necessary for effectively monitoring and inflating the tires to the suitable pressure.
[0004] However, the existing central tire inflation systems are slower and time consuming for detecting pressure in each tire of the automobile and inflating the tire of the automobile. This leads to reduced performance due to slower rate of inflation of the tires.
[0005] Therefore, there is a need for an improved and advanced tire inflation and deflation system with reduced time consumption. Moreover, there is a need for a system and method for faster and automated inflation and deflation of tires in an automobile.
