Globally, safety technology of smart cars is developing for drivers' safety. Because the eye inspection of tire pressure is difficult, automatic sensing of the tire pressure is very important. Tire pressure monitoring system measures tires' pressure and temperature. By using TPMS system we can reduce pollution emissions, fuel consumption and car accident. U.S.A NHTSA made a law to use TPMS on cars...
In this paper we perform the analysis of the popular TPMS (tire pressure monitoring systems) and their application for traffic management purposes. In particular, we evaluate several of the commercially available TPMS devices and analyze their architecture and communication features. Furthermore, we propose the architecture of an external sensor device used for effective eavesdropping of TPMS ID data...
This paper describers the history and trends of application about TPMS, mainly introduces the basic principles of transmitter based TPMS, the structure of the system, as well as the main features of components. To solve the problem of reducing the power of the direct-type TPMS system from the engineering Application Perspective, It focuses on software processes of achieving low power consumption and...
In view of the automobile tire security problem, designs the tire pressure monitor system. The hardware system by the pressure transmitter, the micro controller and receives and dispatches RF to be composed, completes the tire pressure and temperature signal gathering, the launch duty through the CAN line transmission; The receiver receive pressure information carries on processing, the driver real-time...
In this paper, the anti-flat tire design process is divided into two parts: the tire module and the host module. The micro-controller MC68HC908RF2 is the core of the tire module. The integrated sensor MPXY8020A executes tire pressure and temperature measuring. The transmitter integrated inside the micro-controller executes wireless transmittal task. MC33594 executes wireless receive task in the host...
All sensors or sensor systems previously used for tire measurements have one common feature - the sensors are part of electrically closed circuits and electrical connections are used to form the closed circuits. In this paper, we present a new tire safety monitoring system using a recently developed method for designing, powering and interrogating sensors developed at NASA. In lieu of sensors being...
The paper deals with RF tire pressure and temperature monitoring (TPM) systems for automotive. Currently, most systems are characterized by an unidirectional link from the RF TPM sensors on the wheels' rim to the receiving/processing unit on the vehicle chassis. This way the battery-powered transmitter is always active wasting power also in parking mode, when TPM is not required Without a feedback...
