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 buildup that can lead to catastrophic failure of the tire, such as cracking, component separation, or blowout. 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.

Download or read book Evaluation of Effects of Tire Size and Inflation Pressure on Tire Contact Stresses and Pavement Response written by and published by . This book was released on 2006 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: A specific objective was to establish how tire contact stresses may be modeled in existing layered elastic programs to better approximate the effects of non-uniform tire contact pressure distributions, and account for differences in tire construction, tire load, and tire inflation pressure on predicted pavement response. To this end, researchers assembled a data base of measured tire contact stresses and performed a comparative evaluation of methods for representing tire contact pressure distributions in existing models to predict performance-related pavement response variables. A computer program called TireView was developed that provides estimates of tire contact area as a function of tire type, tire load, and tire inflation pressure and predicts the stress distribution at the tire-pavement interface based on polynomial interpolations of measured tire contact stresses in the data base. A method for predicting pavement response using layered elastic analysis is proposed that is based on the predicted tire contact area.

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.
Download or read book Low Power Tire Pressure Monitoring System written by Sravanthi Goparaju and published by . This book was released on 2008 with total page 118 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Operation Bigfoot was initiated by the United States Deaprtment of Agriculture (USDA) forest Service in 1988 to implement central tire inflation (CTI) to reduce the impact of commodity production such as timber and minerals on the forest environment. Cooperative work with other Federal agencies, industry and standards associations, manufacturers, and insurance industry representatives has helped make CTI technology viable and safe for commercial use. Accomplishments include validation of truck and road benefits, tire standards for low inflation pressures, and commercial availability of CTI equipment for trucks and trucks and trailer combinations over 24,000 pounds GVW (gross vehicle weight). Structures tests and demonstration projects indicate the benefits of using lowered tire pressures are real and that they can be implemented to reduce impacts on forest ecosystems. Verified benefits include: 20-30 percent reduction in required road aggregate thickness with CTI; 50-90 percent reduction in road surface maintenance with CTI; 10-85 percent reduction in road related sediment with CTI; Reduced driver injury and fatigue; Reduced vehicle operation and maintenance costs. Additional tests are planned to evaluate the effects of lowered tire pressure on pavement damage during thaw weakened periods, reduction in sediment due to reduced maintenance blading, and measured reduced impacts to the trucks. These and other planned studies will help implement CTI technology. For the covering abstract of this conference, see IRRD number 863140.
