Title:
TRANSCEIVER WITH INSTALLATION DATA EMBEDDED THEREIN, ON-BOARD TRANSCEIVER, AND AUTOMATICALLY OPERATED ROAD SYSTEM
Document Type and Number:
Japanese Patent JP3836778
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a transceiver with installation data embedded therein, using electric field data communication permitting accurate acquisition of positional information and vehicle information on a vehicle traveling on a road; an on-board transceiver, which is mounted on the vehicle and uses the electric field data communication permitting the provision of the correct vehicle information; and an automatically operated road system, which carries out the electric field data communication with the on-board transceiver, and can accurately and surely perform road traffic control, based on the high-resolution positional information and the vehicle information acquired with the plurality of transceivers with installation data embedded therein.
SOLUTION: The vehicle information from the vehicle traveling on a road is received by the electric field data communication via an electric field transmitting means. The vehicle information is combined with the installation data and transmitted, via an input/output circuit to an external, for instance, such as a traffic monitoring base station composing the automatically operated road system. In addition, external information, such as road traffic control information received from such the outside, is combined with the installation data and is transmitted to the vehicle, via the electric field transmission means, by the electric field data communication.
