  • AUTOMATIC TYRE PRESSURE MONITORING SYSTEM USING WIRELESS COMMUNICATON Prof
    AUTOMATIC TYRE PRESSURE MONITORING SYSTEM USING WIRELESS COMMUNICATON Prof. Mr. Prashant. G. Salunkhe 1, Mr. Harshal R. Kulthe 2, Mr. Saiprasad N. Kolhe 3, Mr. Ayaan A. Khan4 1 Guide Department of Electronics and Telecommunication, 2 3 4 Research Scholar, Sandip Foundation, SITRC College, Nasik, Maharashtra (India) ABSTRACT Tyre pressure monitoring system (TPMS) is an electronic system that monitors the air pressure of an automobile tyre and alerts the driver by displaying the real pressure or just a warning light. This project is focused on designing and developing a direct TPMS which the measurement of the air pressure is taken directly using pressure sensor. Suitable components are researched to design the prototype. Main components needed are pressure sensor, voltage-to-frequency converter, transmitter, receiver, and frequency-to-voltage converter. To power the prototype, energy is chosen through wheel rotation. Main components need to be calibrated to ensure the consistency and precision of the prototype in reporting the pressure. Calibration for pressure sensor is performed by simply applying a known value of pressure and the output voltage is measured. For voltage-to- frequency and frequency to-voltage converters, a known value of voltage or frequency is applied and the output is monitored using voltmeter and oscilloscope. The results show promising data by proving the relationship between the input and output for each component. As for the conclusion, although there are many problems and limitations faced, this prototype is a promising product in real world application. I. INTRODUCTION Every year, many accidents occurred and for certain cases, accidents are caused by under-inflated tyres.

  • Development of a Steer Axle Tire Blowout Model For
    DEVELOPMENT OF A STEER AXLE TIRE BLOWOUT MODEL FOR TRACTOR SEMITRAILERS IN TRUCKSIM THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Krishnan Veeraraghavan Chakravarthy Graduate Program in Mechanical Engineering The Ohio State University 2013 Master's Examination Committee: Dr. Dennis A. Guenther, Advisor Dr. Gary Heydinger Copyright by Krishnan Chakravarthy Veeraraghavan 2013 ABSTRACT Tractor Semitrailer handling is one of the key issues in today’s highway traffic safety research. When accidents happen with tractor semitrailers, possibilities of multiple vehicle crashes are always high. Thus it is important to study the handling and control of tractor trailers in accident scenarios. Tire blowout is one of the most common types of failure which may cause vehicle crashes. With experimental testing for such studies being expensive, vehicle dynamic simulation goes a long way in supplementing the capabilities of real field testing. The primary goal of this thesis is to develop a tire blowout model for a tractor semitrailer in TruckSim¬¬TM. Experimental data from a left steer axle tire blowout of a tractor trailer is considered for modeling. The effect of tire blowout on vehicle dynamic aspects of the tire like rolling resistance, effective rolling radius, vertical stiffness and other tire forces are studied. The tractor semitrailer model is developed from previously conducted braking simulation models in TruckSim. From the experimental data, the behavior of the tractor trailer and the left steer axle tire are studied. A tire blowout model for the left steer axle of the tractor is created within TruckSim for simulation.

NEED FOR TIRE PRESSURE MONITORING BACKGROUND • A tire-pressure monitoring system (TPMS) is a system that detects a tire that has low inflation pressure and warns the driver. • Because a run-flat tire is designed to be driven a limited distance and at limited speed after it loses air pressure, a method of alerting the driver had to be found. • There were two systems used, indirect and direct, until the 2008 model year when the use of direct- reading pressure systems was required by law.

  • Study on the Stability Control of Vehicle Tire Blowout Based on Run-Flat Tire
    Article Study on the Stability Control of Vehicle Tire Blowout Based on Run-Flat Tire Xingyu Wang 1 , Liguo Zang 1,*, Zhi Wang 1, Fen Lin 2 and Zhendong Zhao 1 1 Nanjing Institute of Technology, School of Automobile and Rail Transportation, Nanjing 211167, China; [email protected] (X.W.); [email protected] (Z.W.); [email protected] (Z.Z.) 2 College of Energy and Power Engineering, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China; fl[email protected] * Correspondence: [email protected] Abstract: In order to study the stability of a vehicle with inserts supporting run-flat tires after blowout, a run-flat tire model suitable for the conditions of a blowout tire was established. The unsteady nonlinear tire foundation model was constructed using Simulink, and the model was modified according to the discrete curve of tire mechanical properties under steady conditions. The improved tire blowout model was imported into the Carsim vehicle model to complete the construction of the co-simulation platform. CarSim was used to simulate the tire blowout of front and rear wheels under straight driving condition, and the control strategy of differential braking was adopted. The results show that the improved run-flat tire model can be applied to tire blowout simulation, and the performance of inserts supporting run-flat tires is superior to that of normal tires after tire blowout. This study has reference significance for run-flat tire performance optimization.
