Available in PDF, EPUB and Kindle. Book excerpt: More than 1/4 of cars & 1/3 of light trucks on U.S. roadways have one or more tires underinflated 8 pounds per square inch (PSI) or more below the level recommended by the vehicle manufacturer. A decrease in tire pressure can be caused by poor maint., driving habits, punctures, road conditions, & the quality of material used in tire construction. Under normal driving conditions, air-filled tires can lose from 1 to 2 psi per month as air permeates through the tires. The following questions are addressed: What is the impact of tire underinflation on safety & fuel economy, & what actions has the fed. gov¿t. taken to promote proper tire inflation?; & What technologies are currently available to reduce underinflation & what are their implications for safety & fuel economy?

Book excerpt: Proper tire inflation is important for several reasons. Underinflated tires experience a greater amount of sidewall flexion than properly inflated tires, resulting in decreased fuel economy, sluggish handling, longer stopping distances, increased stress to tire components, and heat build-up that can lead to catastrophic failure of the tire, such as cracking, component separation, or blow-out. These catastrophic failures can cause loss of vehicle control and may result in a crash. This book presents an analysis of the data collected through the Tire Pressure Monitoring System-Special Study (TPMS-SS) as it pertains to the effectiveness of TPMS in promoting proper tire inflation.

Available in PDF, EPUB and Kindle. Book excerpt: "Power management is considered to be an important aspect in designing battery operated Tire Pressure Monitoring Systems (TPMS) as it helps to prolong the lifespan of the battery. There are several methods that can be used to design a low power tire-pressure and service monitoring system. One of the most common methods for power reduction is the duty cycle method. This thesis suggests an idea of implementing the TPMS in combination with a separate Radio Frequency Identification (RFID) circuit, especially a very low power (active or passive) RFID whose sole purpose is to detect the interrogating signal. This RFID circuit which can operate at a typical frequency of 125 kHz is used to turn ON a higher power transmitter which is initially in SLEEP state and soon after entering the active state performs the communication, updating, etc. Once the desired task is completed, the high power transmitter returns to SLEEP state or is turned off until the next interrogation. The implementation of SLEEP mode to minimize power consumption is discussed in detail and the currents consumed by the microcontroller in SLEEP and ACTIVE modes are measured and recorded. The microcontroller in SLEEP mode consumed a current of 17[mu]A which reduced the overall average current consumed by the microcontroller and the pressure sensor. Furthermore, this method promises an improvement in the battery life and the calculations showing this improvement are discussed with the example of an AA battery with 2800mAh battery life."--Abstract.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Recommended Practice defines the system and component functions, measurement metrics, and testing methodologies for evaluating the functionality and performance of ground vehicle tire pressure maintenance (ATIS) systems (systems which automatically restore the inflation pressure to its specified level), and recommended maintenance practices for these systems within the known operating environments.These systems are recommended to address all serviceable tires as originally installed on a vehicle by the OEM and/or specialty vehicle manufacturer, and for the aftermarket (including replacement or spare parts) are recommended (but optional) to address all tire/rim combinations installed after initial vehicle sale or in-use dates.This document is applicable to all axle and all wheel combinations for the following vehicle types - single unit powered vehicles exceeding 7257 kg (16 000 lb) gross vehicle weight rating (GVWR), and multi-unit vehicle combinations, up to three towed units, which use an SAE J560 connector for power and/or communication, or equivalent successor connector technology. For combination vehicles including two or more trailers, the dolly axles are also included. The included vehicles can be newly manufactured vehicles or existing vehicles, fitted with air or hydraulic braking systems.SPECIAL NOTE: Equipment known as dual tire equalizers' are commonly used with this category of vehicles. When employing an ATIS system, dual tire equalizers systems are not recommended as they run counter to the purpose of the maintenance system.NOTE: The following systems are not being addressed in this edition of the subject document. 1The management system types and more mature/complex versions of maintenance and management types, to include on-board reporting/storage/retrieval data/control capabilities, will be addressed separately by future changes/additions to this document series. 2Tire pressure monitoring systems - These systems have been addressed under SAE J2848-1. Today the world of mobility is served extensively by tires which are pneumatic in design. To function correctly, these tire designs need pneumatic pressure to derive their performance characteristicsoptimum tread wear, fuel economy, ride quality, or fatigue lifehence the value of keeping the retained pressure at design levels ranks high. While periodic inspection and the periodic action of adjusting the inflation pressure while a vehicle is at rest has been the norm for maintaining pressure, the need to hold tire inflation pressures closer to their design targets over time, even while operating a vehicle on the open road at highway speeds, becomes apparent. The minimum performance capabilities recommended in the following document support these needs. Within the medium and heavy-duty vehicle industry, the equipment supplier community has responded to the need to maintain inflation pressure, by developing various tire pressure systems which automatically re-inflate the tire/wheel assemblies even while operating on the highway. Because these systems do not require any intervention or action by the operator, operators will eventually come to rely upon these systems to maintain tire inflation pressure. It is therefore important that all marketed systems provide an adequate level of performance to assure continued in-service safety. Tires and wheels are integral components of tire pressure systems. The system attributes for tire pressure systems described herein assume an appropriate fitment of tire and wheel for each application, and that these tire pressure systems are not dependent on the performance or physical characteristics of the tire or wheel components. The substitution of one tire/wheel assembly for another tire/wheel assembly of another configuration, appropriate for the vehicle system, shall not render the tire pressure system inoperative, so long as it provides a pneumatic chamber for the inflation gas. Under SAE J2848-1, the system functions and performance expectations for tire pressure monitoring systems have been established. The subject document (SAE J2848-2) addresses tire pressure maintenance systems for which it is essential that the performance and communications to the driver be consistent with that established for tire pressure monitoring systems (see Figure 1). SAE J2848-2 has been reaffirmed to comply with the SAE Five-Year Review policy. While tire pressure maintenance systems do not relieve the driver of his immediate responsibility to take the recommended maintenance action, these systems must still keep the driver informed of the status of the pressure level and make him aware when the system applied is no longer performing its intended function.This document incorporates the attributes of pressure maintenance systems into the management of tire inflation pressure while retaining the alerts and warnings so vitally important to the driver.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE recommended practice defines the system and component functions, measurement metrics, testing methodologies for evaluating the functionality and performance of ground vehicle CTIS. Systems of this type allow the driver to select the operational tire pressure set point (TPSP) based on off-highway conditions, and, upon returning to highway operations, maintain the inflation pressure to the vehicle specified level.These systems are recommended to address all serviceable tires as originally installed on a vehicle by the OEM and/or specialty vehicle manufacturer, and, for the aftermarket (including replacement or spare parts) are recommended (but optional) to address all tire/rim combinations installed after initial vehicle sale or in-use dates.Systems for use by military and some other very rigorous off-road applications require such extreme performance requirements, particularly at very high and low temperature and other combat-based extremes that such applications may fall outside the recommended parameters of the subject document. In those cases, it's the responsibility of the procuring customer, vehicle OEM, and applicable component(s) OEM to determine what compromises might be required, and the suitability of design and performance solutions that may be outside of those recommended here.This document is applicable to all axle and all wheel combinations for the following vehicle types, but does not preclude it's use on other vehicle types - single unit powered vehicles exceeding 7257 kg (16,000_US lbs) gross vehicle weight rating (GVWR), and multi-unit vehicle combinations, up to three (3) towed units, which use an SAE J560 connector for power and/or communication, or equivalent successor connector technology. For combination vehicles including two or more trailers, the dolly axles are also included. The included vehicles can be newly manufactured vehicles or existing vehicles, fitted with air or hydraulic braking systems.Special Note: Equipment known as dual tire equalizers' are commonly used with this category of vehicles. When installing a CTIS system, dual tire equalizers systems are not recommended as they run counter to the purpose of the management system.NOTE: The following systems are not being addressed in this edition of the subject document. 1Tire Pressure Monitoring Systems - these systems have been addressed under SAE J2848-1. 2Tire Pressure Maintenance Systems - these systems have been addressed under SAE J2848-2. Within the medium and heavy-duty vehicle industry, the equipment supplier community has responded to the need to manage inflation pressure for greater vehicle operational performance when transitioning from improved roadways to unimproved roadways and back, by developing onboard adjustable tire pressure systems. The central tire inflation system (CTIS) is one such system. Through a CTIS, the vehicle driver from the cab position is capable of selecting a pressure level based on the ground flotation conditions, and the vehicle load, for uninterrupted operations. Because operators will expect these systems to provide the selected level of pressure and to maintain that level of pressure especially as the vehicle returns to highway operations, it is important that all marketed systems respond with a minimum level of performance to assure continued in-service safety.In the "off-road" or unimproved roadway environment, the driver typically will operate at a reduced vehicle speed and may choose a reduced tire inflation pressure. Under these conditions, it is important to maintain a balance between the tire's flotation performance at high deflection and the tire's durability. These characteristics are particular to each tire manufacturer's product, and therefore it is not practical to define one universal set of operating criteria nor a singular limiting threshold for the off-road environment. At the same time, when these vehicles return to highway operations, it is expected that tire pressure systems of this category, having survived the harsh environments to which they were exposed, will be able to bring the tire's inflation pressure back to the specified highway pressure level, and maintain it.For both SAE document SAE J2848/1 and SAE J2848/2, the system performance and communications to the driver functions have been made coherent and consistent. Under this document, it is essential that the driver communications and performance thresholds, especially when operating to highways conditions, also be consistent with the document series. Each management system must still keep the driver informed of the status of the pressure level and make him aware when the system installed is no longer performing its intended function. This document captures the attributes of pressure management systems while retaining the alerts and warnings so vitally important to the driver.

Available in PDF, EPUB and Kindle. Book excerpt: Tires are the interface between a vehicle and the ground providing forces and isolation to the vehicle. For vehicle safety, stability, maintenance, and performance, it is vital to estimate or measure tire forces, inflation pressure, and contact friction coefficient. Estimation methods can predict tire forces to some extent however; they fail in harsh maneuvers and are dependent on road surface conditions for which there is no robust estimation method. Measurement devices for tire forces exist for vehicle testing but at the cost of tens of thousands of dollars. Tire pressure-monitoring sensors (TPMS) are the only sensors available in newer and higher end vehicles to provide tire pressure, but there are no sensors to measure road surface condition or tire forces for production vehicles. With the prospect of autonomous driving on roads in near future, it is paramount to make the vehicles safe on any driving and road condition. This is only possible by additional sensors to make up for the driver's cognitive and sensory system. Measuring road condition and tire forces especially in autonomous vehicles are vital in their safety, reliability, and public confidence in automated driving. Real time measurement of road condition and tire forces in buses and trucks can significantly improve the safety of road transportation system, and in miming/construction and off-road vehicles can improve performance, tire life and reduce operational costs. In this thesis, five different types of sensors are designed, modelled, optimized and fabricated with the objective of developing an intelligent tire. In order to design these sensors,~both electromagnetic generator (EMG) and triboelectric nanogenerators (TENG) are used. In the first two initial designed sensors, with the combination of EMG and TENG into a single package, two hybridized sensors are fabricated with promising potential for self-powered sensing. The potential of developed sensors are investigated for tire-condition monitoring system (TCMS). Considering the impressive properties of TENG units of the developed hybridized devices, three different flexible nanogenerators, only based on this newly developed technology, are developed for TCMS. The design, modelling, working mechanism, fabrication procedure, and experimental results of these TENG sensors are fully presented for applications in TCMS. Among these three fabricated sensors, one of them shows an excellent capability for TCMS because of its high flexibility, stable and high electrical output,and an encapsulated structure. The high flexibility of developed TENG sensor is a very appealing feature for TCMS, which cannot be found in any available commercial sensor. The fabricated TENG sensors are used for developing an intelligent tire module to be eventually used for road testing. Several laboratory and road tests are performed to study the capability of this newly developed TENG-based sensor for tire-condition monitoring system. However the development of this sensor is in its early stage, it shows a promising potential for installation into the hostile environment of tires and measuring tire-road interacting forces. A comparative studies are provided with respect to Michigan Scientific transducer to investigate the potential of this flexible nanogenerator for TCMS. It is worth mentioning that this PhD thesis presents one of the earliest works on the application of TENG-based sensor for a real-life system. Also, the potential of commercially available thermally and mechanically durable Micro Fiber Composite (MFC) sensor is experimentally investigated for TCMS with fabricating another set of intelligent tire. Several testing scenarios are performed to examine the potential of these sensors for TCMS taking into account a simultaneous measurement from Michigan Scientific transducer. Although both flexibility and the cost of this sensor is not comparable with the fabricated TENG device, they have shown a considerable and reliable performance for online measuring of tire dynamical parameters in different testing scenarios, as they can be used for both energy harvesting and sensing application in TCMS. The extensive road testing results based on the MFC sensors provide a valuable set of data for future research in TCMS. It is experimentally shown that MFC sensor can generate up to 1.4 $\mu W$ electrical power at the speed of 28 $[kph]$. This electrical output shows the high capability of this sensor for self-powered sensing application in TCMS. Results of this thesis can be used as a framework by researchers towards self-powered sensing system for real-world applications such as intelligent tires.
