Use of 13.56 MHz transponders for vehicle infrastructure communication

Abstract

To ensure active safety, various techniques are being used by car manufacturers. This paper relates how communication between vehicles and infrastructures by means of transponders can be used. In the first part, it reminded the communication principle. Then, results of simulation of the internal architecture of the reader are presented as well as the type and the structure of the exchanged information. At the end, a fast discussion shows that the two-axle vehicle model was used to justify the transponders organization in the tread. To assure an 8 cm picking up with regards to the ideal trajectory distance, it is necessary to arrange the transponders of all the meters.
