Abstract

In a mobile system and a mobile management system, when an emergency notification that an urgent car 3 is approaching is transmitted from a base station 5 to a general owner-driven car 1, the distance between the general owner-driven car 1 and the urgent car 3 is calculated on the basis of the current position of the general owner-driven car 1 and the current position of the urgent car 3 under the control of a CPU 11. If the distance is within a predetermined value, the base station notifies the driver of the general owner-driven car that the urgent car is approaching.

Claims

1. A mobile system which is mounted on a mobile unit, comprising:

a position measuring section for measuring the current position of said mobile unit;

an information transmission section for transmitting the current position measured by said position measuring section to a base station;

an information reception section for receiving the information that another mobile unit is approaching to said mobile unit from said base station; and

a controller for controlling said mobile unit to transfer to an emergency state on the basis of the information received by said information reception section.

2. The mobile system according to claim 1, wherein said controller controls a notification section to notify the driver of said mobile unit of the notice information transmitted from the base station or the notice information memorized in advance.

3. The mobile system according to claim 1, further comprising a speaker, wherein said controller reduces the output of sound information which is output from said speaker.

4. A mobile management system comprising:

a current position receiving section for receiving the current position of a mobile unit from a mobile system which is mounted on said mobile unit, and the current position of another mobile unit from a mobile system which is mounted on said another mobile unit different from said mobile unit; and

an information transmitting section for transmitting the required information to said mobile unit on the basis of the current position of said mobile unit and the current position of said another mobile unit which are received by said current position receiving section.

5. The mobile management system according to claim 4, further comprising a selector for selecting said mobile unit located within a predetermined distance from said another mobile unit, on the basis of the current position of said mobile unit and the current position of said another mobile unit which are received by said current position receiving section, wherein said information transmitting section transmits the required information to said mobile unit selected by said selector.

6. The mobile management system according to claim 4, further comprising a selector for selecting said mobile unit located in a range where said another mobile unit can reach within a predetermined time, on the basis of the current position of said mobile unit and the current position of said another mobile unit which are received by said current position receiving section, wherein said information providing section provides the required information to said mobile unit selected by said selector.

7. The mobile management system according to claim 4, wherein said required information is the information indicating that said another mobile unit is approaching.
