Document Type and Number:
WIPO Patent Application WO/2011/135677
Kind Code:
A1
Abstract:
Provided is a vehicle-mounted device which can reduce the amount of data of the positional information of other vehicles captured by a communication device, and also provided are a vehicle-mounted communication device and a vehicle-mounted information processor which are used in the vehicle-mounted device. The vehicle-mounted device discerns a positional relationship, which is formed on the basis of map information, with an object captured by a communication device (30). The positional relationship is discerned by means of an information processor (20) which processes positional information of the object as required. The communication device (30) is provided with a coordinate conversion unit (33) which converts the positional information of the captured object into coordinate information of a coordinate system that is set at a limited resolution with respect to the map information, and the communication device (30) transfers to the information processor (20) the coordinate information produced by said conversion.
