On-board communication terminal and information service center communicating with on-board communication terminal
First Claim
1. An on-vehicle communication system including first radio communication means for transmitting predetermined data having state information in the detection of an abnormal state, the predetermined location information and a terminal ID to an information service center on occurrence of a predetermined event,said on-vehicle communication system comprising:
- an on-vehicle terminal main unit having the first radio communication means to communicate with the information service center;
a mobile terminal detachable from said on-vehicle terminal main unit, andmeans for detecting a relative distance between said on-vehicle terminal main unit and said mobile terminal,wherein said means switches a main system for communications of said on-vehicle communication system,wherein said mobile terminal includes voice communication means,wherein said on-vehicle terminal main unit and said mobile terminal can communicate with each other via second radio communication means, andwherein if said first radio communication means has finished transmitting the predetermined data to the information service center, said mobile terminal has the second radio communication means transmit data for voice communication to the information service center via said on-vehicle terminal main unit.

Abstract
The invention provides an on-vehicle communication terminal that secures a report to a center and safety of a crew by providing short-range radio communication means in the on-vehicle communication terminal, separately configuring a mobile terminal provided with a part of the functions of a conventional on-vehicle terminal detached therefrom, and letting the crew who are escaping carry a mobile terminal.
That is, an on-vehicle terminal (1) according to the invention includes location information detecting means (11), state sensor (14) for detecting an abnormal state and outputting the state information, first radio communication means (12) for transmitting predetermined data including state information, location information on a plurality of locations and a terminal ID to the information service center (2) on occurrence of a predetermined event, and second radio communication means (16) for providing radio communications between the on-vehicle terminal (1) and the mobile terminal (3). The mobile terminal (3) includes second radio communication means (31) and further location information detecting means (11) and a state sensor (14). Thus, by configuring an on-vehicle communication terminal with a combination of the on-vehicle terminal (1) and the mobile terminal (3), the crew can report to the information service center (2) while securing safety in the event of an accident.
