Abstract

There is provided a positioning system including a communication device which includes a connector configured to engage with a connector provided to a vehicle, a vehicle communication section configured to receive vehicle speed information or travelling distance information of the vehicle from the vehicle via the connector, and an information processing device-communication section configured to transmit, to an information processing device, transmission information based on the vehicle speed information or the travelling distance information acquired by the vehicle communication section, and the information processing device which includes a communication section configured to receive the transmission information from the communication device, and a position calculation section configured to calculate a current position based on the vehicle speed information or the travelling distance information.

Claims

1. A positioning system comprising:

a communication device which includes

a connector configured to engage with a connector provided to a vehicle,

a vehicle communication section configured to receive vehicle speed information or travelling distance information of the vehicle from the vehicle via the connector, and

an information processing device-communication section configured to transmit, to an information processing device, transmission information based on the vehicle speed information or the travelling distance information acquired by the vehicle communication section; and

the information processing device which includes

a communication section configured to receive the transmission information from the communication device, and

a position calculation section configured to calculate a current position based on the vehicle speed information or the travelling distance information.

2. The positioning system according to claim 1,

wherein the information processing device further includes a navigation section configured to show a route to a destination using the calculated position information.

3. The positioning system according to claim 1,

wherein the connector provided to the vehicle is a connector for fault diagnosis.

4. The positioning system according to claim 3,

wherein the communication device further includes an angular velocity detection sensor configured to acquire an angular velocity of the vehicle, and

wherein the information processing device-communication section transmits, as the transmission information to the information processing device, the angular velocity acquired by the angular velocity detection sensor and the vehicle speed information or the travelling distance information.

5. The positioning system according to claim 1,

wherein the communication device has a shape such that the connector is fixed on the connector provided to the vehicle when the connector engages with the connector provided to the vehicle.

6. A communication device comprising:

a connector configured to engage with a connector provided to a vehicle;

a vehicle communication section configured to receive vehicle speed information or travelling distance information of the vehicle from the vehicle via the connector; and

an information processing device-communication section configured to transmit, to an information processing device, transmission information based on the vehicle speed information or the travelling distance information acquired by the vehicle communication section.

7. The communication device according to claim 6, further comprising

an angular velocity detection sensor configured to acquire an angular velocity of the vehicle.

8. The communication device according to claim 7,

wherein the information processing device-communication section transmits, as the transmission information to the information processing device, the angular velocity acquired by the angular velocity detection sensor and the vehicle speed information or the travelling distance information.

9. The communication device according to claim 7, further comprising

a position calculation section configured to calculate a current position based on the angular velocity acquired by the angular velocity detection sensor and the vehicle speed information or the travelling distance information,

wherein the information processing device-communication section transmits the position information as the transmission information to the information processing device.

10. The communication device according to claim 6,

wherein the information processing device-communication section communicates wirelessly with the information processing device in accordance with a short range wireless communication standard.

11. A positioning method of a positioning system which includes a communication device that is provided inside a vehicle by a connector being engaged with a connector provided to the vehicle and that includes a vehicle communication section and an information processing device-communication section, and which includes an information processing device that includes a communication section configured to communicate with the information processing device-communication section and a position calculation section configured to calculate a current position, the positioning method comprising:

receiving, by the vehicle communication section, vehicle speed information or travelling distance information of the vehicle from the vehicle via the connector;

transmitting, by the information processing device-communication section, transmission information based on the vehicle speed information or the travelling distance information acquired by the vehicle communication section, to the information processing device;

receiving, by the communication section, the transmission information; and

calculating, by the position calculation section, the current position based on the vehicle speed information or the travelling distance information.
