Abstract

A control device including a control section configured to cause a ranging process of measuring a distance between communication devices to be executed a designated number of times, and control a subsequent process that is a process of using a ranging value that satisfies a designated allowable value, on a basis of whether or not at least any of a plurality of ranging values that have been acquired satisfies the designated allowable value. The control section controls start of the subsequent process when the ranging value that satisfies the designated allowable value is acquired.

First claim

What is claimed is:

1. A control device comprising:
a controller, including a processor and a memory, configured to cause a ranging process of measuring a distance between communication devices to be executed a designated plurality of times repeatedly for a predetermined time, and control a subsequent process that is a process of using a ranging value, amongst a plurality of ranging values acquired during the designated plurality of times, that satisfies a designated allowable value acquired during the repeated measuring of the distance between the communication devices, on a basis of whether or not at least any of the plurality of ranging values that have been acquired satisfies the designated allowable value,
wherein the controller controls start of the subsequent process when the ranging value that satisfies the designated allowable value is acquired,
wherein the controller causes the ranging process to be executed the designated plurality of times for each combination of the communication devices, and controls the ranging process and the subsequent process, and
wherein, when the ranging value that satisfies the designated allowable value is acquired, the controller cancels a subsequent ranging process with regard to a combination between the communication devices from which the ranging value that satisfies the designated allowable value is acquired,
wherein the ranging process includes transmission of a first ranging signal from one of the communication devices to another communication device, transmission of a second ranging signal from the other communication device to the one communication device in response to the first ranging signal, and calculation of the ranging value on a basis of time it takes to transmit and receive the first ranging signal and the second ranging signal, and
wherein the ranging process includes a process of transmitting the first ranging signal and the second ranging signal through ultra-wideband wireless communication.

2. The control device according to claim 1 ,
wherein, when the ranging value that satisfies the designated allowable value is acquired, the controller cancels all subsequent ranging processes.

3. The control device according to claim 1 ,
wherein the controller sequentially repeats control to cause the ranging process to be executed the designated plurality of times, for each combination of the communication devices.

4. The control device according to claim 1 ,
wherein the controller controls the designated plurality of times to cause the ranging processes of respective combinations of the communication devices to be sequentially executed.

5. The control device according to claim 1 ,
wherein the controller performs control in such a manner that the subsequent process is not executed in a case where all the ranging processes that have been acquired do not satisfy the designated allowable value.

6. The control device according to claim 1 ,
wherein the subsequent process includes at least any of an unlocking process and an activation process, the unlocking process being a process of unlocking a lock device installed in an open/close mechanism including an openable/closable part, the activation process being a process of activating a predetermined device.

7. The control device according to claim 1 ,
wherein the ranging process includes a process of calculating a ranging value of a distance between a communication device installed in a vehicle and a communication device installed in a portable device.

8. A control device comprising:
a controller, including a processor and a memory, configured to cause a ranging process of measuring a distance between communication devices to be executed a designated plurality of times repeatedly for a predetermined time, and control a subsequent process that is a process of using a ranging value, amongst a plurality of ranging values acquired during the designated plurality of times, that satisfies a designated allowable value acquired during the repeated measuring of the distance between the communication devices, on a basis of whether or not at least any of the plurality of ranging values that have been acquired satisfies the designated allowable value,
wherein the controller controls start of the subsequent process when the ranging value that satisfies the designated allowable value is acquired,
wherein the ranging process includes transmission of a first ranging signal from one of the communication devices to another communication device, transmission of a second ranging signal from the other communication device to the one communication device in response to the first ranging signal, and calculation of the ranging value on a basis of time it takes to transmit and receive the first ranging signal and the second ranging signal, and
wherein the ranging process includes a process of transmitting the first ranging signal and the second ranging signal through ultra-wideband wireless communication.

9. A non-transitory storage medium having a program stored therein, the program causing a computer to achieve a control function of causing a ranging process of measuring a distance between communication devices to be executed a designated plurality of times repeatedly for a predetermined time, and controlling a subsequent process that is a process of using a ranging value, amongst a plurality of ranging values acquired during the designated plurality of times, that satisfies a designated allowable value acquired during the repeated measuring of the distance between the communication devices, on a basis of whether or not at least any of the plurality of ranging values that have been acquired satisfies the designated allowable value,
wherein the control function controls start of the subsequent process when the ranging value that satisfies the designated allowable value is acquired,
wherein the control function causes the ranging process to be executed the designated plurality of times for each combination of the communication devices, and controls the ranging process and the subsequent process,
wherein, when the ranging value that satisfies the designated allowable value is acquired, the control function cancels a subsequent ranging process with regard to a combination between the communication devices from which the ranging value that satisfies the designated allowable value is acquired,
wherein the ranging process includes transmission of a first ranging signal from one of the communication devices to another communication device, transmission of a second ranging signal from the other communication device to the one communication device in response to the first ranging signal, and calculation of the ranging value on a basis of time it takes to transmit and receive the first ranging signal and the second ranging signal, and
wherein the ranging process includes a process of transmitting the first ranging signal and the second ranging signal through ultra-wideband wireless communication.

10. A control device comprising:
a controller, including a processor and a memory, configured to cause a ranging process of measuring a distance between communication devices to be executed a designated plurality of times, and control a subsequent process that is a process of using a ranging value, amongst a plurality of ranging values acquired during the designated plurality of times, that satisfies a designated allowable value, on a basis of whether or not at least any of the plurality of ranging values that have been acquired satisfies the designated allowable value,
