Abstract

A control device including a control section configured to obtain distance measurement information, and perform a process according to the obtained distance measurement information, the distance measurement information being information that is obtained by transmitting and receiving a distance measurement signal between at least two communication devices, and the distance measurement signal being a signal that is transmitted and received to measure a distance between the two communication devices.

First claim

1 . A control device comprising a control section configured to obtain distance measurement information, and perform a process according to the obtained distance measurement information, the distance measurement information being information that is obtained by transmitting and receiving a distance measurement signal between at least two communication devices, and the distance measurement signal being a signal that is transmitted and received to measure a distance between the two communication devices.

2 . The control device according to claim 1 , wherein the distance measurement information is the information that is obtained when a first communication device that is one of the two communication devices transmits a first distance measurement signal, an other second communication device receives the first distance measurement signal, the second communication device transmits a second distance measurement signal as a response to the first distance measurement signal, and the first communication device receives the second distance measurement signal.

3 . The control device according to claim 2 , wherein the distance measurement information includes information that indicates a time from a transmission time of the first distance measurement signal to a reception time of the second distance measurement signal in the first communication device.

4 . The control device according to claim 2 , wherein the distance measurement information includes information that indicates a transmission time of the first distance measurement signal and a reception time of the second distance measurement signal in the first communication device.

5 . The control device according to claim 2 , wherein the distance measurement information includes information that indicates a time from a reception time of the first distance measurement signal to a transmission time of the second distance measurement signal in the second communication device.

6 . The control device according to claim 2 , wherein the distance measurement information includes information that indicates a reception time of the first distance measurement signal and a transmission time of the second distance measurement signal in the second communication device.

7 . The control device according to claim 2 , wherein the distance measurement information includes a distance measurement value that is calculated based on information obtained by transmitting and receiving the distance measurement signal, and indicates the distance between the first communication device and the second communication device.

8 . The control device according to claim 2 , wherein the control section performs calculation of a distance measurement value indicating the distance between the first communication device and the second communication device based on the distance measurement information as the process according to the distance measurement information.

9 . The control device according to claim 7 , wherein the control section performs decision that is based on the distance measurement value indicating the distance between the first communication device and the second communication device as the process according to the distance measurement information.

10 . The control device according to claim 2 , wherein the control section transmits at least one of the distance measurement information and information that indicates a result of the process performed according to the distance measurement information to at least one of the first communication device and the second communication device.

11 . The control device according to claim 2 , wherein the control section transmits at least one of the distance measurement information and information that indicates a result of the process performed according to the distance measurement information to another device other than the first communication device and the second communication device.

12 . The control device according to claim 2 , wherein
one of the first communication device and the second communication device is mounted on a vehicle, and other one of the first communication device and the second communication device is a device that is carried by a user of the vehicle.

13 . A communication device comprising:
a wireless communication section configured to perform wireless communication with another communication device; and a control section configured to control a process of transmitting distance measurement information to a control device configured to execute communication with each of the communication device and the another communication device, the distance measurement information being information that is obtained by transmitting and receiving a distance measurement signal between the wireless communication section and the another communication device, and the distance measurement signal being a signal that is transmitted and received to measure a distance between the two communication devices.

14 . An information processing method comprising obtaining distance measurement information, and performing a process according to the obtained distance measurement information, the distance measurement information being information that is obtained by transmitting and receiving a distance measurement signal between at least two communication devices, and the distance measurement signal being a signal that is transmitted and received to measure a distance between the two communication devices.
