Tire is the most essential part of automobile and it plays crucial role in ensuring safe driving. Even then, almost every automobile on the road run with either one or more under inflated tires. Detailed survey has come with result that drop in tire pressure by just few psi leads to the reduction in gas mileage, tire life ,safe driving and vehicle performance. Unawareness of exact pressure requirement, sudden environmental changes are also some of causes for tire running with improper pressure. Automatic tire pressure controlling and self-inflating system ensures correct pressure in the tire all the time. Drop in pressure is detected by hissing sound made by tire and system will starts refilling the tire automatically according to the requirement of the tire. This system is named automatic because it checks the tire pressure constantly using pressure gauge and accordingly gives alert signals to the driver. Aim of this project is to stabilize all automobile tires with ideal pressure, make system absolutely automatic, achieve satisfactory fuel efficiency, construct an affordable system, increase tire life and reduce accident rate has been achieved by installing the system in vehicle.
Self-Inflating Tyre Pressure Safety System Suitable for the Automotive Industry
2018
Four wheelers are often used by most of the people in today’s life for their comfort and sophistication. Some of the vehicle accidents are taken place, due to the burst of tyre, it mainly occur because of under inflation which creates overheating during which causes loss of human life and also severe damage to the vehicle because of uncontrollable vehicle motion. To overcome the problem, this paper focuses on achieving accurate pressure in the vehicle tyre which can be attained by introducing a self-inflating system for tyre while in running condition with a low cost. This system checks the tyre pressure periodically and inflates automatically to the precisepressure. Self-inflation pressure has added advantages like increase fuel economy, reduction of distance while applying braking, improves tyre life. Approximately 3/4 of all automobiles operate with at least has one underinflated tyre. The main causes of under inflation in tyres are because of natural leakage, temperature changes...
Effects of Tire Pressure Monitoring Systems on Tire Pressures in Consumer Vehicles
Transportation Research Record, 2007
(FMVSS) No. 138 in June 2002. FMVSS 138 requires that a tire pressure monitoring system (TPMS) be installed in all new passenger cars, multipurpose passenger vehicles, trucks, and buses that have a gross vehicle weight rating of 4,536 kg (10,000 lb) or less, except vehicles with dual wheels on an axle. These systems are currently being phased in to the mix of vehicles on the roadways. Existing TPMS technologies fall into two general categories, those with sensors that measure tire pressure directly (direct systems) and those that estimate pressure based on wheel speed (indirect systems). Despite evidence that direct systems outperform the less costly indirect systems (4), either approach can be used to satisfy the current FMVSS 138. As specified in FMVSS 138, all TPMSs are required to detect when one or more tires are underinflated relative to a predetermined trigger threshold. The trigger threshold ultimately adopted in FMVSS 138 is 25%. Thus all TPMSs are required to alert the driver when one or more tires are 25% or more underinflated relative to the pressure recommended by the vehicle manufacturer. Although the development of TPMSs, as well as standardized rules for their efficacy, has the laudable goal of reducing the population of underinflated tires in consumer vehicles, the authors are unaware of any solid empirical data that document the effect that TPMSs have on pressure levels in consumers' tires. There are at least three possible ways in which the presence of TPMSs might affect tire pressure. First, TPMSs might successfully reduce the frequency and severity of tire underinflation problems. That would presumably stem from a TPMSrelated increase in drivers' awareness of underinflation conditions, which would in turn encourage tire maintenance behaviors. A second possibility, however, is that TPMSs might increase the frequency of tire underinflation problems. That possibility might result from drivers' believing that their vehicles have automated monitoring systems that supplant their responsibility to check their tire pressure manually (i.e., "I don't need to check my tire pressure; my car does that for me."). From that perspective, it is possible that drivers could mistakenly interpret a lack of an alert as a tacit reassurance that they have no underinflated tires, potentially unaware that TPMSs are not required to issue an alert until the 25% underinflation threshold is reached. A third possibility is that TPMSs might have little or no effect on users' tire pressure. Because the factors that influence consumers' tire maintenance behaviors are not well understood, it is not known whether the addition of an in-vehicle information system will necessarily alter habits that may be deeply ingrained.
DESIGN AND FABRICATION OF AUTOMATIC TYRE PRESSURE INFLATION SYSTEM
Industrial Engineering Journal, 2024
The main aim of our project is to achieve accurate tyre pressure. This is achieved by introducing an automated system for tyre inflation. This system checks the tyre pressure regularly and inflates automatically to the correct tyre pressure. Proper tyre inflation pressure improves fuel economy, reduces braking distance, improves handling, and increases tyre life, while underinflation creates overheating and can lead to accidents. Approximately 3/4 of all automobiles operate with at least one underinflated tyre. The main causes of underinflation are natural leakage, temperature changes, and road hazards. Drivers typically do not check tyre pressure unless they notice unusual vehicle performance. Visual checks are often insufficient to determine under-inflation. In 2000, the U.S. Transportation Recall Enhancement, Accountability, and Documentation Act (TREAD) requested that the National Highway Transport Safety Authority (NHTSA) investigate the implementation of a pressure drop warning system on vehicles. Beginning with 2006 models, all passenger cars and trucks in the United States are required to have tyre-pressure inflation systems (TPMSs). A TPMS is a driver-assist system that warns the driver when the tyre pressure is below or above the prescribed limits.

Engineering of Tire Pressure Controlling Device: An Invention Towards Successful Product Development
Tire pressure plays an important role in ensuring safe and economical driving. Even then, many vehicles with under inflated tires are observed to be on the road due to the unawareness of the fact that properly inflated tires can safe tire life up to 20% which is nine months more of its life span. It can also save fuel from 4% to 10%, increase braking efficiency up to 20%, lightens steering system and ease self steer. Improper maintenance and operation failure of air pressure kiosks are the main reason why users seldom inflate their tires at the gas stations. Besides that, long awaiting queue at the kiosk and not knowing the exactly required tire pressure of their own vehicle is another cause for tires running with improper pressure. Therefore, a method of how to ease the users to inflate their tires is engineered and invented. Automatic Tire Pressure Controller (ATPC) has been idealized to ensure correct pressure is inflated into the tires regardless of the setting on the pressure source: e.g. kiosk, compressor, foot inflator, etc. The device will alert the user upon reaching the appropriate pressure by a hissing sound. This product attracts many users especially ladies who often being the second driver who are always unsure of the pressure of their tires.
To Study on Implementation of Tyre Inflation System for Automotive Vehicles
The Tire Inflammation System is based on the idea to maintain uniform tire pressure of an automobile and to reduce tire wear, increase fuel efficiency and increased overall vehicle safety.The main working principle of the Tire Inflation System is that the compressed air is passed through the rotary joint into the nozzle fitted in Rim of the Wheel. The rotary joint thus allows the air to flow through itself along with providing the rotary motion of the wheel assembly. Thus the rotary joint makes it possible work out the idea. A compressor is used which gets its power supply from the battery. When the pressure falls below desired level the compressor pumps air through the rotary union to the Tyre and inflates it.
Pressure gauge accuracy and tire maintenance awareness among vehicle owners in Birnin Kebbi, Nigeria
Jurnal Sistem dan Manajemen Industri
Aside from human factors, tire blowouts and other tire imperfections are major contributors to the persistently high road accident rate. While tire imperfections are categorized as part of the mechanical factors affecting road accident, the tire maintenance personnel and the vehicle owners' human behavior plays a significant role in ensuring that accidents due to tire imperfections are minimized. Therefore, this study aims to determine the accuracy of the pressure gauges used by tire maintenance personnel, popularly called vulcanizers in Nigeria, and to determine the level of awareness of vehicle owners about the basic information that affects the safe use of tires on the road. The study consists of two stages. The first stage investigates the accuracy of the pressure gauges used by twenty vulcanizers in four different districts in Birnin Kebbi, the northwestern part of Nigeria. The second stage was an online survey regarding the tire maintenance behavior of 87 participants, wh...
Method for Tyre Pressure Monitoring
This method presents vibration based continuous tyre monitoring system using the machine learning approach. It is important for the driver to know as soon as the tyre is punctured in order to prevent the rim and the treads of the tyre from extreme damage. This study provides an insight to tyre pressure monitoring using vibration analysis. The model for fault diagnosis uses the concept that the vibration signals in case of normal and punctured tyre have characteristic differences and thus can be used for indirect monitoring of tyre pressure. Statistical features are extracted from these signals and then feature selection is carried out in order to select the best features for feature classification. Feature classification is carried out using the Simple Logistic function is used as the classifier. The data model thus built helps to distinguish between vibration signals from a normal tyre and a punctured tyre.
