First Claim
Patent Images
1. An identification information examination method for an information obtaining apparatus mounted in a vehicle, comprising:
- transmitting information including vehicle related information which is related to the vehicle and identification information that allows a transmission source of the vehicle related information to be identified;
receiving the transmitted information;
processing the received information and performing an examination concerning the identification information included in the received information; and
when the examination concerning the identification information is performed, changing a reception sensitivity of the reception device by changing at least one of (i) a target reception voltage of the reception device and (ii) an orientation of the reception device for receiving a signal from a first reception sensitivity which is used when an examination concerning the identification information is not performed to a second reception sensitivity which is used when the examination concerning the identification information is performed.

Abstract
In an identification information examination mode, reception sensitivity of a reception device in an information obtaining mode is reduced. In the reception device, information transmitted from a transmission device mounted in a vehicle adjacent to the host vehicle is not received, and identification information transmitted from a transmission device mounted in the host vehicle is received. Then, an examination is performed by comparing the received identification information with the identification information stored in memory in advance.
