Problems solved by technology

As a result, responsiveness to user lock indications may be impaired
In addition, in the independent confirmation method, as the number of portable devices increases, the time required for non-existence judgment becomes longer, so the possibility of occurrence of the above-mentioned worrying phenomenon becomes higher.
[0011] In addition, it is not limited to the vehicle control related to the locking of the vehicle door, and when executing other vehicle controls that have the condition that there is no portable device in a predetermined area as the execution condition, it is also possible to similarly discover the time required for non-existence determination. Problems such as reduction of user convenience

Deformed example 1

[0132] In the above-mentioned embodiment, as step S202 , it is disclosed that the interior determination unit F3 transmits an LF signal requesting a collective response signal to all the smart keys 2 as a collective response request signal, but the present invention is not limited thereto. The all-response request signal transmitted in step S202 may be configured as an LF signal requesting return of a response signal only to a part of the smart keys 2 . Specifically, it is as follows.

[0133] According to the procedure of the door locking process in the above-mentioned embodiment, the interior non-existence confirmation process is performed on the condition that the exterior presence confirmation process is performed and the presence of at least one smart key 2 is confirmed in the locked area Lx. In other words, at the stage of performing the exterior presence confirmation process, it has been determined that at least one of the plurality of smart keys 2 exists in the locked ...

Deformed example 2

[0141] In the above-mentioned embodiment and modification 1, as an independent confirmation process (S202), it is disclosed that each smart key 2 (that is, independently ) is a method of judging whether or not the vehicle is present in the vehicle compartment. However, the method of independently determining the location of the smart key 2 is not limited to this. For example, it is also possible to Figure 15 As illustrated, the interior determination unit F3 determines whether each smart key 2 is present in the interior of the vehicle by sequentially transmitting individual response request signals requesting return of the response signal to only one designated smart key 2 . Figure 15 The operation of each device when any one of the smart keys 2b exists in the vehicle compartment is exemplified.

[0142] In addition, the exterior presence unit F4 may be configured to determine whether or not the smart key 2 exists in the locked area Lx for each smart key 2 by sequentially ...

Deformed example 3

[0144] In the above-mentioned embodiment, an embodiment in which the process of confirming the absence of the vehicle is executed after the process of confirming the process of confirming the presence of the vehicle is executed is triggered by pressing the lock button 15 , but the present invention is not limited thereto. For example, it can also be used as Figure 16 As shown, the door locking process is configured such that all the doors of the vehicle Hv are closed as a trigger to execute the non-existence confirmation process inside the vehicle compartment, and then execute the presence confirmation process outside the vehicle compartment when the lock button 15 is pressed.

[0145] Below, use Figure 16 The shown flowchart describes the door locking process disclosed as Modification 3. FIG. Start when the vehicle information acquisition unit F1 detects that all doors of the vehicle Hv are closed Figure 16 The flow chart shown is sufficient. The door locking process of...

Abstract

An authentication device for a vehicle is used in a vehicle provided with a plurality of portable devices. The authentication device is provided with a first communication unit (12) that uses, as a communication region, a first region preset for the vehicle; a second communication unit (13) that sets, as a communication region, a second region set for the vehicle so as not to overlap the first region; a first region determination unit (F3) that determines whether or not the portable device is present in the first region on the basis of the communication status with the portable device by the first communication unit; a second area determination unit (F4) that determines whether or not the portable device is present in the second area on the basis of the communication status with the portable device by the second communication unit; and a control execution unit (F5) that executes prescribed vehicle control on the basis of the determination by the first region determination unit that there is no portable device in the first region and the determination by the second region determination unit that there is at least one portable device in the second region.

Description

[0001] Cross References to Related Applications [0002] This application is based on Japanese Patent Application No. 2018-97178 filed on May 21, 2018, and its content is cited here. technical field [0003] The present disclosure relates to a vehicle authentication device that performs predetermined vehicle control such as locking a vehicle door by performing wireless communication with a portable device that is an electronic key. Background technique [0004] Conventionally, there has been a vehicle authentication in which vehicle controls such as locking, unlocking, and starting the engine are carried out based on wireless communication with a portable device (so-called smart key) carried by the user, based on the confirmation of the presence of the portable device in a predetermined area. device. The vehicle authentication device described above, for example, when a lock command is input from a lock switch provided on the outer surface of the vehicle body, confirms that...
