A system is mounted on a vehicle and includes a sensor configured to perform a detection process that detects a fingerprint of a finger touching the sensor in order to perform a fingerprint authentication process, and a controller. The controller is configured to: (i) control a power supply of the vehicle to be ON when a predetermined authentication process through a predetermined communication with another device other than the sensor is successful, the predetermined authentication process being different from the fingerprint authentication process, and (ii) suppress the detection process that detects the fingerprint in response to the power supply of the vehicle being ON and the predetermined authentication process being successful.

Fingerprint authentication device

A system including: a first communication device and a second communication device, wherein the first communication device and the second communication device perform the wireless communication that conforms to first wireless communication standards, and, when one of the first communication device and the second communication device decides that information obtained by the wireless communication that conforms to the first wireless communication standards satisfies a predetermined condition, perform the wireless communication that conforms to second wireless communication standards for measuring a distance between the first communication device and the second communication device.

System, and communication device

A polling processing unit executes a polling process for detecting a device that performs NFC communication. An NFC communication processing unit executes a communication process of performing NFC communication with a mobile device detected by the polling process. Power consumption associated with execution of the communication process is larger than power consumption associated with execution of the polling process. When authentication of the mobile device by an authentication processing unit is completed, or when the execution of the communication process continues for a prescribed time period, the NFC communication processing unit executes a stop process of stopping the communication process until the execution of the communication process is permitted.

Communication control device, vehicle including the same, and communication control method

A control device and a control method that can reduce power consumption for waiting for reception of a signal are provided. The control device includes a controller configured to control a communicator such that the communicator performs wireless communication with another device. The controller controls a reception waiting time of a predetermined signal which is transmitted from the other device by the wireless communication on the basis of acquired acquisition information.

Control device and control method

A communication unit includes: a plurality of wireless communication units configured to perform wireless communication with another communication device; and a control unit configured to estimate a relative position of the other communication device relative to the communication unit, wherein the control unit estimates the relative position of the other communication device on the basis of a plurality of distance measurement values indicating a distance between each of the plurality of wireless communication units and the other communication device obtained by each of the plurality of wireless communication units performing wireless communication with the other communication device, and a position characteristic including a position of each of the plurality of wireless communication units in the communication unit.

Communication unit, communication device, and position estimating method

A control device comprising, a control section configured to control an authentication process of performing a process related to device authentication together with at least one communication device on a basis of information included in a signal received through wireless communication with the communication device, wherein the control section performs control in such a manner that a signal including authentication information that is information to be used for the authentication process is transmitted to the communication device through the wireless communication, the authentication information varying depending on signal types, which are types of roles of signals to be transmitted to the communication device in the authentication process.

A control device controls an authentication process related to device authentication together with at least one communication device on a basis of information included in a signal received through wireless communication with the communication device. The control device performs the control in such a manner that authentication information is changed for each process group in which the authentication process is repeated more than once. Signals transmitted or received in the authentication process include a trigger signal, a request signal, and a response signal. The control device executes the process group in which the authentication process is repeated more than once for the trigger signal, the request signal, and the response signal, and changes the authentication information to be used for each of the trigger signal, the request signal, and the response signal each time the process group is executed.
