(Overview and features)
First, the outline and features of the keyless entry system according to the present invention will be described. FIG. 1 is a block diagram illustrating the configuration of the keyless entry system according to the first embodiment. As shown in the figure, the keyless entry system 1 performs “portable device identification processing” for identifying whether or not the identification information transmitted from the smart key 20 is identification information corresponding to the vehicle control device 10. Is.

  Here, the keyless entry system 1 according to the present invention acquires the personal authentication information of the user of the smart key 20, and the user of the smart key 20 acquires the smart key 20 based on the acquired personal authentication information. The main feature of the “use period update process” is that the use period of the smart key 20 is updated when it is authenticated whether or not it is a valid holder and the smart key 20 is authenticated. In addition, such “use period update process” can prevent spoofing by a third party while ensuring the convenience of the user.

  This key feature will be described in detail. In this keyless entry system 1, a “use period” is set in the smart key 20 in order to achieve both the convenience of the user of the smart key and the safety against unauthorized use of the smart key. To do.

  In the first and second embodiments, as a measure to be taken when the user of the smart key 20 is authenticated by the holder authentication unit 17a as not being a valid holder of the smart key 20, the period of use of the smart key 20 is taken. Although an example of discarding data has been described, the present invention is not limited to this, and measures related to theft prevention such as alarm control may be taken.

  In the first and second embodiments, examples in which separate identification information and authentication information are used as portable device identification information and personal authentication information have been described. However, the present invention is not limited to this, and the smart key 20 is used. Thus, the personal authentication information may be held for the period of use, and the personal authentication information may be used as portable device identification information.

  In the first and second embodiments, examples where the functional units according to the present invention (that is, the fingerprint sensor, the holder authentication unit, and the usage period update unit) are all present on the vehicle control device 10 side or the smart key 20 side have been described. However, the present invention is not limited to this, and the present invention is implemented if the vehicle control device 10 and the smart key 20 as a whole include at least one set of a fingerprint sensor, a holder authentication unit, and a usage period update unit. It can be carried out analogously to Examples 1 and 2. For example, the vehicle control device 10 and the smart key 20 may each include a functional unit according to the present invention (that is, a fingerprint sensor, a holder authentication unit, and a usage period update unit).

  In addition, among the processes described in this embodiment, all or part of the processes described as being performed automatically can be performed manually, or the processes described as being performed manually can be performed. All or a part can be automatically performed by a known method.
