2. The communications device according to claim 1, wherein

the communication unit provided for mobile communications is configured to receive a recommended drive information for the vehicle, and

the recommended drive information is calculated based on the vehicle travel data sent to the server by the communication unit provided for fixed-line communications and based on the partial data sent to the server by the communication unit provided for mobile communications.

5. The communications device according to claim 1, wherein

the communication unit provided for mobile communications is configured to receive a recommended drive information for the vehicle, and

the recommended drive information is calculated in the server on the basis of the vehicle travel data sent to the server by the communication unit provided for fixed-line communications and the partial data sent to the server by the communication unit provided for mobile communications.

6. The communications device according to claim 5, wherein

the vehicle travel data includes at least an information of driver'"'"'s steering, and a state of the vehicle constituted by a vehicle speed, an acceleration/deceleration, a yaw rate and a vehicle location information.

7. The communications device according to claim 6, wherein

a data-communication condition setting unit configured to previously set a format of the partial data is provided in the vehicle.

8. The communications device according to claim 7, wherein

the partial data set by the data-communication condition setting unit is sent in real time.

9. The communications device according to claim 5, wherein

the vehicle is an electric vehicle, and

the communication unit provided for fixed-line communications is configured to send data through a charging cable during a charging of the electric vehicle.

10. The communications device according to claim 5, wherein

the communication unit provided for fixed-line communications is configured to send data through a wireless LAN.

11. The communications device according to claim 5, wherein

the recommended drive information is an information for recommended drive route.

12. The communications device according to claim 1, wherein

the communication unit provided for fixed-line communications is configured to send the vehicle travel data which was accumulated in the vehicle-travel-data accumulating unit and which exists after a data range sent during a previous stopped state of the vehicle.

3. A communications system for a vehicle, comprising:

a server provided in a data center;

a vehicle-travel-data accumulating unit provided in the vehicle and configured to accumulate a travel data of the vehicle;

a communication unit provided in the vehicle for mobile communications and configured to send a partial data of the vehicle travel data accumulated in the vehicle-travel-data accumulating unit to the server, the partial data being selected from the vehicle travel data on a predetermined condition; and
