Document Type and Number:
WIPO Patent Application WO/2007/097185
Kind Code:
A1
Abstract:
A communication device (100) connectable with a mobile body is provided to exchange the
present position information of a plurality of mobile bodies in a group with each
other. An acquiring unit (101) acquires the present position information of
a mobile body. A transmitting unit (102) sends the present position information acquired
by the acquiring unit (101) to other than the mobile bodies in a group. A detecting
unit (103) detects whether electric power supplied to itself is cut off or not,
or whether a connection with the mobile bodies is cut off or not. When the detecting
unit (103) detects that the electric power or the connection with the mobile bodies
is cut off, a control unit (104) controls the transmitting unit (102) to send the
other mobile bodies terminating information to the effect that the transmission
of the position information is terminated.
