VEHICLE-MOUNTED DEVICE, VEHICLE-MOUNTED COMMUNICATION DEVICE, AND VEHICLE-MOUNTED INFORMATION PROCESSOR
First Claim
1. A vehicle-mounted device, which is configured to discern a target positional information, which is a positional relationship with a target, on the basis of map information, the device comprising:
- a vehicle-mounted communication device for obtaining target positional information, which is positional information of the target; and
a vehicle-mounted information processor, which discerns the target positional relationship by processing the target positional information as required, whereinthe vehicle-mounted information processor is provided with a display device having a screen, on which the target positional information and the map information are visualized and displayed,the vehicle-mounted communication device includes a coordinate conversion unit, which uses a conversion factor to convert the target positional information to coordinate information of a coordinate system that corresponds to a resolution of the screen,the vehicle-mounted communication device is configured to transfer the coordinate information to the vehicle-mounted information processor, andthe vehicle-mounted information processor includes a conversion factor computing unit, which calculates the conversion factor on the basis of a scale in each case of the map information and the screen resolution.

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. The positional relationship is discerned by means of an information processor, which processes positional information of the object as required. The communication device is provided with a coordinate conversion unit, 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 transfers to the information processor the coordinate information produced by the conversion.
