[0019] First, the outline of one embodiment of the present invention will be described. As described above, in recent years, a technique for performing authentication based on the result of transmitting and receiving signals between devices has been developed. For example, Patent Document 1 discloses a technology in which a vehicle-mounted device transmits and receives signals with a portable device to authenticate the portable device. By using such an authentication technique, for example, when the portable device held by the user is within a communicable distance from the vehicle, functions such as unlocking the door of the...

Abstract

The present invention addresses the problem of providing a structure capable of suppressing an increase in power consumption while ensuring the accuracy of the distance between measurement devices. A control device is provided with a control unit that causes a distance measurement process for measuring the distance between communication devices to be executed a predetermined number of times, and that performs distance measurement on the basis of whether or not at least one of a plurality of obtained distance measurement values satisfies a predetermined allowable value. And a control unit that controls a subsequent process, which is a process in which the distance measurement value satisfying the prescribed allowable value is used, and that controls the start of the subsequent process when the distance measurement value satisfying the prescribed allowable value is acquired.

Description

technical field [0001] The present invention relates to a control device and a computer-readable storage medium. Background technique [0002] In recent years, techniques have been developed to measure the distance between devices based on the result of transmitting and receiving signals between the devices. For example, Patent Document 1 below discloses a technique in which a vehicle-mounted device transmits and receives signals to and from a portable device to measure the distance between the vehicle-mounted device and the portable device. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2018-48821 [0004] Even in the case where the distance measurement process based on signal transmission and reception is performed as described above, it is assumed that the distance measurement process is executed a plurality of times in order to improve the accuracy of the acquired distance measurement value. However, as the number of executions of ranging processing increase...
