DISPLAY APPARATUS AND DISPLAY METHOD
First Claim
1. An inter-vehicle communication method comprising:
- a frame control signal transmitting step of one of a plurality of in-vehicle communication apparatuses having functions of both a base station and a mobile station transmitting a frame control signal;
a step of said in-vehicle communication apparatus that receives said frame control signal during a frame control signal reception standby operation analyzing received said frame control signal;
a step of, when said in-vehicle communication apparatus that transmitted said frame control signal can be recognized by means of said analysis, transmitting a channel affiliation request signal containing that station'"'"'s own address;
a step of said in-vehicle communication apparatus that transmitted said frame control signal receiving said channel affiliation request signal during a channel affiliation request reception standby operation and functioning as a base station correspondent in-vehicle communication apparatus; and
an inter-vehicle communication step of said base station correspondent in-vehicle communication apparatus and a mobile station correspondent in-vehicle communication apparatus that is said in-vehicle communication apparatus of an address of said channel affiliation request signal performing dedicated short-range communication.

Abstract
A DSRC in-vehicle communication apparatus (1) operates as a base station based on the DSRC communication standard when a base station function section (3) is selected by an operation function selection section (2), and operates as a mobile station based on the DSRC communication standard when a mobile station function section (4) is selected. After a plurality of vehicles equipped with a DSRC in-vehicle communication apparatus (1) have been disposed, an inter-vehicle communication system is constructed by the function of each DSRC in-vehicle communication apparatus (1) being selected, and vehicles whose function has been selected as base station or mobile station performing DSRC communication.

2. An in-vehicle communication apparatus comprising:
-
an operation function selection section that selects operation as a mobile station on receiving a frame control signal during a frame control signal reception standby operation, and selects operation as a base station on receiving a channel affiliation request signal during channel affiliation request signal reception standby after transmitting said frame control signal; a base station function implementation section that, when operation as a base station has been selected by said operation function selection section, performs communication with a mobile station of an address contained in received said channel affiliation request signal; and a mobile station function implementation section that, when operation as a mobile station has been selected by said operation function selection section, transmits said channel affiliation request signal containing that station'"'"'s own address when a base station can be recognized by analyzing received said frame control signal, and performs communication with a base station. - View Dependent Claims (3)
