A central vehicle-information management center gathers individual pieces of information on the state of a vehicle on a real-time manner by: acquiring and gathering pieces of information on the position of the vehicle from a reflection signal reflected by an artificial satellite as a result of reflection of a position signal transmitted by an antenna provided on the vehicle to the artificial satellite; and acquiring and gathering a signal reflected by the artificial satellite as a result of reflection of a signal used for representing information on control of the vehicle or information on conditions of vehicle parts and transmitted from the antenna to the artificial satellite or transmitted by the vehicle through a wireless-communication apparatus such as a DSRC (Dedicated Short Range Communication) device or a cellular phone. As a result, with such a central vehicle-information management center, it is possible to provide a method and an apparatus, which can be used for gathering information on a vehicle and capable of continuously collecting detailed information on the present state of a vehicle with a high degree of reliability and in a real-time manner.

1. Field of the Invention
The present invention relates to a method and an apparatus for gathering information on a movable body by using a satellite communication system or another movable-body communication system such as a ground-wave digital communication system, a cellular phone and a DSRC (Dedicated Short Range Communication) system.
2. Description of the Prior Art
FIG. 1 is a system conceptual diagram showing an embodiment of the present invention;
FIG. 2 is a block diagram showing functions of car onboard equipment;
FIG. 3 is a block diagram showing functions of a central vehicle-information management center;
A preferred embodiment of the present invention is explained by referring to diagrams.
FIG. 1 is a system conceptual diagram. In the system shown in FIG. 1, information on the state of a vehicle 1 generated by the vehicle 1 is split into two pieces of information. One of the two pieces of information, mainly, information on the position of the vehicle, is transmitted to a central information management center 6 from car onboard equipment 2 by way of an antenna 3 and an artificial satellite 4 on a real-time manner from time to time. The car onboard equipment 2 accommodates a variety of control apparatuses provided on the vehicle 1. The information on the position of the vehicle 1 may include a latitude and a longitude received from a navigation terminal (also referred to as a car navigation apparatus) employed in the car onboard equipment 2. The other piece of information, mainly, information on the driver, is transmitted to the central information management center 6 typically from the car onboard equipment 2 by way of a DSRC device or a cellular phone 12.
A signal transmitted by the vehicle is reflected by the artificial satellite 4 to the central vehicle-information management center 6 as information on a vehicle by typically an S-band satellite communication and broadcasting system (HEO) 5.
