Description

The present invention relates to a vehicle entry system, and more particularly to a vehicle entry system that enables locking and unlocking of a vehicle while leaving operation keys inside the vehicle.

Conventionally, an entry system for locking and unlocking a vehicle by using an operation key having a communication function without inserting an operation key into a keyhole of a door has become widespread. Further, if the user who is the passenger who owns the operation key approaches the vehicle and touches the touch sensor or the like arranged at the door handle or the vicinity thereof without touching the operation key, the lock and unlock are performed. More advanced entry systems are being developed.

In such an advanced entry system, if the user touches a touch sensor or the like to lock from outside the vehicle while leaving the operation key inside the vehicle, a warning sound is emitted to prevent the user from being locked out. It is a control that does not lock.

On the other hand, for example, when a user exercises or leisurely outside the vehicle, there is a demand to lock the vehicle with the operation key left in the vehicle in order to prevent the operation key from being lost or broken down. However, in the advanced entry system described above, in principle, the user could not lock the vehicle from outside the vehicle while leaving the operation keys inside the vehicle.

To deal with this problem, a technology has been developed to lock the vehicle with an encrypted code while leaving the operation key in the vehicle. In this coding technology, a password of several digits is set in advance, and by pressing the switch for the number of times corresponding to the password, even if the operation key is left inside the vehicle, the vehicle can be operated from outside the vehicle. It can be locked and unlocked.

Patent Document 1 describes an in-vehicle device control device in which a camera is arranged in a vehicle and a user can release a door lock by issuing a specific sign toward the camera. According to this device, the vehicle can be locked without touching the door handle.

However, in the lock / unlock method using the above-mentioned coding technology, the password code is fixed, and if the password code is changed in order to improve security, it is necessary to re-register the password code. The work was complicated. In addition, the switch for entering the password code is in a position where it can be easily touched, so if you enter all the code combinations, theoretically you can unlock it without knowing the password code and lock / unlock it. be able to. Therefore, the lock / unlock method using the coding technology has security concerns. Further, since the number of times the switch is pressed when inputting the password code is increased, the input work is complicated. Furthermore, when using the password code, it is necessary to temporarily stop the function of the operation key that unlocks when approaching the vehicle, and such work is complicated.

Further, the in-vehicle device control device described in Patent Document 1 can be unlocked by recognizing the user's signature with a camera, but even in such a device, a third party other than the user can unlock the signature. There is a risk of unlocking by showing the camera. Therefore, the device described in Patent Document 1 also has a security concern.

The present invention has been made in view of the above circumstances, and an object of the present invention is to easily lock and unlock the vehicle while maintaining high security while leaving the operation keys in the vehicle. The purpose is to provide a vehicle entry system that can be used.

Further, the vehicle entry system of the present invention includes a vehicle, a server capable of communicating with the vehicle, and a display for displaying the first release information for unlocking the vehicle, and the server is a user. In response to the request from the vehicle, a path for permitting the unlocking of the vehicle is transmitted to the vehicle and the display device, respectively, and the display device displays the first release information generated from the path. The vehicle has a display unit, and the vehicle reads from the reading device for reading the first release information displayed on the display unit of the display unit, the second release information generated from the path, and the reading device. It is characterized by having a vehicle control device that unlocks the vehicle when the first release information matches.

Further, in the vehicle entry system of the present invention, when the door is locked while the operation key of the vehicle is present in the vehicle, the vehicle control device unlocks by the operation key or starts the power source of the vehicle. It is characterized by prohibition.

Further, in the vehicle entry system of the present invention, the server invalidates the first release information after the unlock is completed.

Further, in the vehicle entry system of the present invention, when the first release information based on the path issued to another display is registered, the server first registers the first release information of the display. It is characterized by disabling it.

Further, the vehicle entry system of the present invention includes a vehicle, a server capable of communicating with the vehicle, and a display for displaying the first release information for unlocking the vehicle, and the server is a user. In response to the request from the vehicle, a path for permitting the unlocking of the vehicle is transmitted to the vehicle and the display device, respectively, and the display device displays the first release information generated from the path.

Hereinafter, the vehicle entry system 30 according to an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, in principle, the same code number will be used for the same member, and repeated description will be omitted.

FIG. 1 is a schematic view showing the configuration of the vehicle entry system 30 according to the present embodiment. With reference to this figure, the vehicle entry system 30 is composed of a vehicle 10, a display 20 that displays an ID code for unlocking the vehicle 10, and a server 25 that can communicate with the vehicle 10 and the display 20. It is configured. The function of the vehicle entry system 30 is to lock the vehicle 10 while leaving the operation key 12 used for normal entry in the vehicle, and to unlock the vehicle 10 using the display 20 while maintaining high security. Here, the lock means to lock the door 11 and the like of the vehicle 10, and the unlock means to unlock the lock.

The vehicle 10 includes a reading device 15, an external switch 16, an in-vehicle antenna 14, a transmission / reception unit 13, and a vehicle control device 17. Each of these devices is electrically connected via wiring routed inside the vehicle 10.

The reading device 15 is a device for visually reading the first release information displayed on the display unit 21 of the display 20, which will be described later. For example, a reading device having a solid-state image sensor such as a CCD is adopted. As the reading device 15, a dedicated reading device for reading the display unit 21 of the display device 20 can be adopted. Further, a camera for a back monitor arranged near the rear end of the vehicle 10 or a stereo camera arranged near the front end of the vehicle to monitor the situation in front of the vehicle while driving is adopted as the display 20. You can also do it. A barcode reader can also be used as the reading device 15.

The vehicle exterior switch 16 is a touch-type or push-type switch arranged at or near the handle of the door 11 of the vehicle 10, and locks and unlocks the vehicle 10 by touching or pressing the vehicle exterior switch 16. Can be done.

The in-vehicle antenna 14 is an antenna arranged in the vehicle interior, and when the in-vehicle antenna 14 communicates with the operation key 12, the vehicle control device 17 determines whether or not the operation key 12 exists in the vehicle interior.

The transmission / reception unit 13 performs information communication with the display 20 and the server 25 existing outside the vehicle 10 via a communication network such as a telephone communication line.

The vehicle control device 17 is an ECU (Electronic Control Unit) composed of a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory), and controls the operation of each device constituting the vehicle 10. is doing.

The server 25 is installed at a location remote from the vehicle 10. As will be described later, in response to the request of the user 26, a one-time pass (pass) for unlocking the vehicle 10 is generated, and this one-time pass is transmitted to the vehicle 10 and the display 20.

The display 20 is an electronic device that can be carried by the user 26 outside the vehicle, and for example, a smartphone or the like capable of communicating with the server 25 can be adopted. The display 20 includes, for example, a display unit 21 including a liquid crystal display. As will be described later, the display 20 can receive the one-time pass from the server 25 and display the ID code generated from the one-time pass on the display unit 21.

Next, a method of locking and unlocking the vehicle 10 using the vehicle entry system 30 having the above configuration will be described below. FIG. 2 is a flowchart showing a method of locking the vehicle 10, FIG. 3 is a flowchart explaining a method of transferring the first release information (ID code) to another display 20, and FIG. 4 is a flowchart showing a method of unlocking the vehicle 10. It is a flowchart which shows the method of doing.

A method of locking the vehicle 10 provided with the vehicle entry system 30 will be described with reference to FIG. 1 with reference to FIG.

First, in step S10, it is determined whether or not the one-time pass has been issued to the display 20. The one-time pass is provided by the server 25 and has an input code required for generating an ID code described later, and is invalid after being used once. Further, there is a limit to the time during which the one-time pass can be effectively used, and the one-time pass is invalidated after a predetermined time has passed since it was issued by the server 25.

Specifically, the user 26 issues a one-time pass from the display 20 to the server 25 via a communication network, for example, by operating an application installed on the display 20 such as a smartphone. Request to do. The server 25 generates a one-time pass in response to the request, and issues the generated one-time pass to the display 20.

In the present embodiment, the ID code generated from the one-time pass issued toward the display 20 is the first release information, and the ID code generated from the one-time pass issued toward the vehicle 10 is the first release information. 2 Cancellation information. Here, the one-time pass issuance request can be made by operating a device other than the display 20, for example, the user 26 controls the vehicle by operating a touch panel or the like provided on the vehicle 10. The device 17 may request the server 25 to issue a one-time pass via the transmission / reception unit 13 of the vehicle 10. When the one-time pass is issued to the display 20, that is, if YES in step S10, the process proceeds to step S11. On the other hand, if the one-time pass is not issued to the display 20, that is, if it is NO in step S10, the process proceeds to step S12.

In step S11, next, the one-time pass is input to the display 20 and the ID code which is the first release information is registered. Specifically, the application installed on the display 20 generates an ID code from the input one-time pass. If the ID code has already been input to the display 20, the ID code is generated again.

In step S12, it is determined whether or not a one-time pass has been issued to the vehicle 10. Specifically, the server 25 transmits the one-time pass to the vehicle 10 in response to the above-mentioned request of the user 26. The one-time pass transmitted to the display 20 and the one-time pass transmitted to the vehicle 10 are the same pass. The one-time pass issued from the server 25 is stored in a storage device such as a RAM included in the vehicle control device 17 via the communication network and the transmission / reception unit 13. If the one-time pass is issued to the vehicle 10, that is, if YES in step S12, the process proceeds to step S13. On the other hand, if the one-time pass is not issued to the display 20, that is, if it is NO in step S12, the process proceeds to step S14.

In step S13, next, the one-time pass is input to the vehicle control device 17 of the vehicle 10, and the ID code which is the second release information is registered. Specifically, the vehicle control device 17 also has an algorithm for generating an ID code from a one-time pass, like the display 20, and generates an ID code from the input one-time pass by the algorithm. If the ID code has already been input to the vehicle control device 17, the ID code is generated again.

In step S14, it is determined whether or not there is a request from the user 26 to lock the vehicle 10. Specifically, has the user 26 carrying the display 20 locked the door 11 of the vehicle 10 by operating the door knob of the vehicle 10 or a touch switch arranged in the vicinity thereof from the outside of the vehicle 10. Judge whether or not. If the user 26 locks the vehicle 10, that is, if step S14 is YES, the process proceeds to step S15. On the other hand, if the user 26 does not lock the vehicle 10, that is, if step S14 is NO, the process ends without locking the vehicle 10.

In step S15, it is determined whether or not the display 20 is present in the vehicle interior of the vehicle 10. Specifically, the in-vehicle antenna 14 of the vehicle 10 communicates with the display 20, and the vehicle control device 17 determines whether or not the display 20 exists in the vehicle interior according to the communication result. If the display 20 is present in the vehicle interior of the vehicle 10, that is, if YES in step S15, the process proceeds to step S16. On the other hand, if the display 20 does not exist in the vehicle interior of the vehicle 10, that is, if NO in step S15, the process proceeds to step S17.

In step S16, if the operation key 12 is present in the vehicle interior of the vehicle 10, that is, if step S16 is YES, step S18 ends without locking the vehicle 10 in order to prevent confinement. On the other hand, if the operation key 12 does not exist in the vehicle interior of the vehicle 10 and exists outside the vehicle, that is, if NO in step S16, the vehicle 10 is locked because it is not closed in step S19. Further, in this state, since the user 26 can subsequently unlock the vehicle 10 from the outside with the operation key 12, the vehicle 10 is not unlocked by using the display 20. Therefore, in order to improve the security. The ID code of the display 20 described above is invalidated.

If NO in step S15 described above, that is, if there is no display 20 in the vehicle interior of the vehicle 10, specifically, if the user 26 carries the display 20 and is outside the vehicle, in step S17, the vehicle is inside the vehicle. It is determined whether or not the operation key 12 exists. If the operation key 12 is present in the vehicle, that is, if YES in step S17, the vehicle control device 17 locks the vehicle 10 with the operation key 12 confined in the vehicle, and the locking operation is completed. Further, in step S20, the vehicle control device 17 invalidates the ID of the operation key 12 existing in the vehicle in order to prevent unnecessary start of the vehicle 10 and further improve security. As a result, the power source such as the engine or the vehicle drive motor cannot be started by the operation key 12, and the vehicle 10 is not unlocked or the like at an unintended timing.

If NO in step S17, that is, if the operation key 12 does not exist in the vehicle, specifically, if the operation key 12 is locked outside the vehicle while being carried by the user 26, the vehicle control device 17 is the vehicle in step S21. Lock 10. Then, the ID code of the display 20 specified by the above-mentioned one-time pass is invalidated.

With reference to FIG. 3, next, after locking the vehicle 10 as described above, a method of transferring the ID registered in the display 20 owned by the locked user 26 to the display 20 owned by another user 26. explain. Specifically, it is conceivable that a user 26 locks the vehicle 10 by the method shown in FIG. 2 and then requests another user 26 to unlock the vehicle 10. Assuming such a case, in the present embodiment, the ID code can be transferred to the display 20 owned by another user 26 outside the vehicle.

Specifically, first, in step S30, the server 25 determines whether or not the display 20 carried by the user 26 has ID registered. If the display 20 is not registered as an ID, that is, if step S30 is NO, the transfer of the ID code is completed. On the other hand, if the ID code is registered, that is, if step S30 is YES, in step S31, the server 25 determines whether or not the one-time pass has been issued to the display 20 owned by another user. If the one-time pass has not been issued to the display 20 owned by another user, that is, if step S31 is NO, the server 25 proceeds to step S33. On the other hand, if the one-time pass is issued to the display 20 owned by another user 26, that is, if step S31 is YES, the server 25 inputs the one-time pass to the other display 20 in step S32 and IDs. Complete code registration.

Next, in step S33, the server 25 determines whether or not the one-time pass has been issued to the vehicle 10, and if it has not been issued, that is, if it is NO in step S33, the transfer of the ID code ends. .. On the other hand, if the one-time pass is issued to the vehicle 10, that is, if YES in step S33, the vehicle control device 17 registers an ID code indicating another display 20 from the one-time pass in step S34. .. Further, in step S35, the vehicle control device 17 invalidates the ID code related to the first display 20 for which the server 25 issues the one-time pass. By doing so, it is possible to prevent the vehicle 10 from being accidentally unlocked by the first display 20 against the intention of the user 26.

Through each of the above steps, the one-time pass can be copied to the display 20 owned by another user 26, and the vehicle 10 can be unlocked by the display 20 owned by the other user 26. Therefore, after locking the vehicle 10, when the action schedule of the locked user 26 is changed, it is possible to request another user to unlock the vehicle 10, and the degree of freedom when unlocking the vehicle 10. Can be improved.

Next, a method of unlocking the vehicle 10 using the display 20 will be described with reference to FIG.

In step S40, first, the vehicle control device 17 determines whether or not the reading device 15 of the vehicle 10 has a reading request in order for the user 26 to unlock the vehicle 10. This determination can be made, for example, by whether or not the display unit 21 of the display 20 is reflected on the reading device 15 which is a back monitor camera. Further, the presence or absence of this request can also be determined by whether or not a predetermined action (for example, the user 26 operates a switch or the like of the vehicle 10) has been performed. If there is no read request, that is, if NO in step S40, unlocking is not performed.

If there is this reading request, that is, if YES in step S40, the reading device 15 reads the ID code displayed on the display unit 21 of the display 20 in step S41. Here, the ID code is projected on the display unit 21 as, for example, a code arranged two-dimensionally. Further, the vehicle control device 17 determines whether or not the ID code displayed on the display unit 21 and the ID code stored in the vehicle control device 17 match. If they match, that is, if step S41 is YES, the process proceeds to step S42. On the other hand, if they do not match, that is, if step S41 is NO, the vehicle 10 is not unlocked.

In step S42, the vehicle control device 17 unlocks the vehicle 10 in order to allow the user 26 to board, and invalidates the ID code of the display 20 used for unlocking. By doing so, it is possible to prevent the vehicle 10 from being unlocked again with the ID code once used. Further, the ID of the operation key 12 that was invalidated in the above step is enabled, and the engine or the like can be started by using the operation key 12.

In step S43, if there is a request operation by the user 26 and the ID of the vehicle 10 and the ID of the operation key 12 match, the vehicle control device 17 starts the engine and makes the vehicle 10 capable of traveling (the vehicle 10 is ready to travel). YES in step S43, YES in step S44, step S45). On the other hand, if there is no engine start request by the user 26, or if the ID of the vehicle 10 and the ID of the operation key 12 do not match, the vehicle control device 17 ends without starting the engine (NO in step S43, step S43). NO of S44).

By unlocking the vehicle 10 as described above, for example, even if the user 26 outside the vehicle does not hold the operation key 12, the display 20 owned by the user 26 is only held over the reading device 15 of the vehicle 10. Then, the vehicle 10 can be unlocked. Further, when the operation key 12 is not to be carried in the outdoors such as in the sea or mountains, the operation key 12 can be left in the vehicle and the user 26 can carry only the display 20 and perform activities outside the vehicle. The user 26 can enjoy the outdoors without worrying about losing the operation key 12.

Further, when the vehicle 10 is operated by car sharing, there is a possibility that passing the operation key 12 to another user may cause a sense of incongruity. When the server 25 gives a one-time pass, the vehicle 10 can be unlocked. Therefore, car sharing can be performed without handing over the operation key 12. In this case, the engine or the like may be started by the operation key 12 owned by each user 26.

Further, in the present embodiment, since the ID code is newly changed each time the one-time pass is issued to the display device 20, the anti-theft property can be improved without forming a fixed code.

Furthermore, since it is not necessary for the user 26 to stop the function of the operation key 12, the vehicle entry system 30 can be implemented without significantly changing the function of the conventional operation key 12.

Although the embodiments of the present invention have been shown above, the present invention is not limited to the above embodiments.

In the above embodiment, the server 25 transmits each release information to the display 20 and the vehicle 10, but the vehicle entry system 30 can be configured by the vehicle 10 and the display 20 without using the server 25. In this case, each release information can be transmitted and received between the display 20 and the vehicle 10.

Further, in the above embodiment, the ID code is displayed on the display unit 21 of the display 20 owned by the user 26, but the ID code may be printed on a paper medium so that the user 26 owns the paper medium. can.
