Please refer to FIG. The intelligent vehicle electronic key system according to the present invention includes a first user device 11, a second user device 12, a cloud server 13, and a vehicle control unit 21.
The cloud server 13 may be a cloud-based server host. The vehicle control unit 21 is installed in the vehicle 20. Considering that the connectivity between the vehicle control unit 21 and the cloud server 13 is clearly shown, the fact that the vehicle control unit 21 is located outside the vehicle 20 in FIG. It is an intention to show.

The first user device 11 and the second user device 12 are portable electronic devices or wearable electronic devices such as smart phones, tablets, personal computers (PCs), laptop computers, personal digital assistants (PDAs), smart watches, or smart glasses. The device may be, but is not limited to.
As the first user device 11 or the second user device 12, any mobile electronic device having wireless network connection performance, portability, or wearability can be adopted. Wireless network connection performance can be implemented by a wireless network module compliant with Wi-Fi®, ZigBee®, 3G, 3.5G, 4G, or higher mobile standards, and The user device 11 or the second user device 12 can be embedded.

  The first user device 11, the first user device 12, and the vehicle control unit 21 are wirelessly connected to the cloud server 13 through the Internet or other network for them and communicate with each other wirelessly. The communication between them will be described in detail later in conjunction with FIG. 2 and FIG.

  As a premise of a practical example illustrating the technical solution of the present invention, the owner of the vehicle 20 asks his friends or family members to move the vehicle 20 from other locations to the designated location. . The owner is the first user who owns the first user device 11. A friend or family member is a second user who possesses the second user device 12.

  When the first user (i.e., the owner) activates the electronic key sharing function through the first user device 11, the first user device 11 becomes the second user device 12 owned by the second user. Send electronic key information link. After operating the second user device 12 to open the electronic key information link, the second user further operates the second user device 12 to activate the vehicle control function and cloud the vehicle control signal. Transmit to the server 13. The cloud server 13 then sends a vehicle control signal to the vehicle control unit 21 to cause the vehicle control unit 21 to control the operation of the vehicle 20.

Please refer to FIG. 2A and FIGS. 4A to 4D. The first user implements an electronic key application through the first user device 11. As shown in FIG. 4A, the first user device 11 has a first display screen 15.
When the first user executes the electronic key application, the first user interface serves as a user interface when operating the electronic key application on the first display screen 15 of the first user device 11. 16 is shown. When sharing the access right for the electronic key with the second user, the first user performs the electronic key sharing function shown on the first user interface 16 (S11).
In the present embodiment, the electronic key sharing function marked with 160 is displayed in the upper right corner of the first user interface 16. In the present invention, functions implemented on the user interface are implemented by “key press”, “button”, “scroll bar control”, “text box”, and the like, and are selectively presented according to operation functions. For example, when trying to enable or disable the electronic key sharing function, the first user can operate an element on the first user interface 16 related to “scroll bar control” and change the default name of the electronic key. If so, the first user can manipulate elements on the first user interface 16 associated with the “text box”, and so on.
The operations associated with the electronic keys are hereinafter referred to as literal “functions” or “press keys”, “buttons”, “scroll bar control”, and “text box” on the first user interface 16. It may be expressed by a corresponding practical operation, but is not limited thereto.

When the first user chooses to perform the electronic key sharing function 160, a screen on the first user interface 16 corresponding to the electronic key application is shown in FIG. 4B. As shown in FIG. 4B, the electronic key application includes an electronic key function 161 and an instantaneous position function 162.
When the first user selects the instantaneous position function 162, the first user interface 16 displays the parking position coordinates and position information of the vehicle 20. For example, on the first user interface 16 or another user interface that is further activated on the first display screen 15, such as a web-based interface, the information on the instantaneous parking position of the vehicle 20 is digital map, street view information, This can be verified by satellite image or text, but is not limited to this. In other words, when the first user selects the instantaneous position function 162, the vehicle search function for the first user is performed.
The coordinate information of the instantaneous parking position of the vehicle corresponds to the coordinate information of the vehicle control unit 21 in the vehicle 20. One possible solution, including but not limited to the implementation of the instantaneous position function 162, is proposed as follows. The vehicle control unit 21 maintains its connectivity with the cloud server 13 through the Internet, and the vehicle control unit 21 can continuously transmit the coordinate information to the cloud server 13. As such, when the first user device 11 requests the coordinate information of the vehicle 20 through the cloud server 13, the cloud server 13 causes the first user to recognize the coordinate information of the instantaneous parking position of the vehicle 20. The coordinate information of the vehicle control unit 21 can be transmitted to the first user device 11.

After selecting the electronic key function 161, the first user can select the key sharing function 163 for sharing the access right of the electronic key with friends by creating an electronic key (eKey). After the first user selects the key sharing function 163, the screen on the first user interface 16 corresponding to the electronic key application is shown by FIG. 4C. As shown in FIG. 4C, the electronic key application further includes an authority sharing function 164.
After the first user selects the key sharing function 163, the default state of the authority sharing function is enabled, and the first user interface 16 also has a name, authority, and a name for sharing an electronic key that can be shared with friends. Display remaining time. For example, as shown in FIG. 4C, when an electronic key is created, the name of the default electronic key to share and the default remaining time may be, but not limited to, “ekey1” and 1 hour Not.

  Furthermore, when the access right of the electronic key is to be revoked, the first user disables the authority sharing function 164 from the enabled state so that the second user will no longer have the access right of the electronic key. It may be selected or switched to change to a state. In other words, even when the second user receives the electronic key, the electronic key is not effective for the operation.

  In addition, when the access right of the electronic key is to be further shared with another person, in consideration of the similarity, the first user is a user other than the second user in order to share the access right of the electronic key. The key sharing function 163 can be selected on the first user interface 16 again as shown in FIG. This point is not described in detail here.

  When the name of the electronic key shown on FIG. 4C is selected, the selected electronic key is configured and this access right is transmitted. When the electronic key is selected, the first user interface 16 displays the corresponding screen on FIG. 4D. As shown in FIG. 4D, the electronic key application further includes a name setting function 165, an effective time setting function 166, a position sharing function 167, a comment function 168, a transmission function 169, and an activation function 170.

When the first user selects the name setting function 165, the default name of the electronic key is changed to another new name that is better recognizable, especially when the access rights of the electronic key are shared by multiple people at the same time May be. Further, when the first user transmits the authority sharing information to the second user, the name of the electronic key is transmitted and indicated to the second user device 12.
When the first user selects the effective time setting function 166, the time for sharing the access right can be changed. The effective time setting function 166 can be used for setting the remaining time of sharing or setting the specified expiration date in order to easily recognize that the operating condition for sharing the access right of the electronic key is handled. It may be.

  When the first user selects the position sharing function 167, the coordinate information and position information of the parking position of the vehicle 20 may be transmitted in parallel with the transmission of the shared access right information to the second user. When selecting the comment function 168, the first user can enter text about how to use the electronic key within the first user interface 16. This text is used so that the second user recognizes text that is noticed by the first user and commented by the first user to know how to use the electronic key. The text is also shown in FIG. 5B.

  When selecting the send function 169, the first user may have multimedia messaging service (MMS), short message service (SMS), email, and communication software (eg, LINE®, WhatsApp®, Select any one of the communication means including, but not limited to, WeChat®, Snapchat®, Facebook®, Messenger, Vessenger, and Twitter® messages, etc. The sharing access right of the electronic key can be transmitted to the second user device 12 to cause the second user to use the electronic key.

  When selecting the activation function 170, the first user further shares the access right of the extended function with the second user. For example, when the first user selects the activation function 170, the second user can activate the engine of the vehicle 20 through the second user device 12. In contrast, if the activation function 170 is not selected by the first user, the second user can only open or lock the vehicle door through the second user device 12, and the engine of the vehicle 20 Cannot be started. The extended function access right can be exemplified by the above description, but is not limited thereto.

  Still referring to FIGS. 2A and 2B. When selecting the electronic key sharing function (S11), the first user further performs the electronic key sharing function 160 as shown in FIG. 4A, and as discussed above, the electronic key function 161, the instantaneous position, The function 162, the key sharing function 163, the authority sharing function 164, the name setting function 165, the effective time setting function 166, the position sharing function 167, and the comment function 168 can be selectively executed. Next, the first user device 11 transmits the electronic key information link to the second user device 12 by executing the transmission function 169 (S12).

  For example, when the first user device 11 transmits an electronic key information link through the Internet and the cloud server 13, the web address information linked corresponding to the electronic key information link is the SMS, email, or It may be input through an operation interface for operation of communication software. Thus, when an electronic key information link is transmitted to the second user device 12, the electronic key information link received by the second user device 12 is the linked web address information.

During the process of sending the electronic key information link from the first user device 11 to the second user device 12, hashing is introduced to preserve the integrity of the information and authenticate the identification information. For example, the original content of the electronic key information link can be processed by a cryptographic hash function, which may be, but is not limited to, SHA-512. The hash value is obtained after the electronic key information link has been processed by the cryptographic hash function and then transmitted to the second user device 12.
If the second user device 12 receives the hash value and the hash value is authenticated by the cloud server 13, the electronic key information if the hash value is correct or the same as that stored in the cloud server 13 This means that the link has not been tampered with, and this confirms that the second user device 12 is a proper device that can share the access rights of the electronic key. Therefore, it is possible to obtain the effectiveness of maintaining the integrity of the information and authenticating the identification information, and the security when sharing the access right of the electronic key is improved.

Refer to FIG. 5A. The second user device 12 has a second display screen 25. When the second user selects an electronic key information link, i.e., web address information linked from the second user device 12, the second user interface 26 displays the second display screen 25 of the second user device 12. Displayed above.
The second user interface 26 is a web-based interface. When the electronic key information link is clicked on the second user interface 26 (S13), the second user interface 26 displays the web address information 260 linked at the top of the web-based interface.

Refer to FIG. 2A. After the electronic key information link is selected from the second user device 12 (S13), the access right of the second user device 12 is further authenticated. Specifically, after step S13, the second user device 12 transmits an authority authentication request that may be generated by hashing the electronic key to the cloud server 13 (S19). In this embodiment, since the authority authentication request is generated when the first user device 11 activates the electronic key sharing function and transmits the access right request to the cloud server 13, the cloud server 13 follows the access right request. The authority authentication request is returned to the first user device 11. Next, the first user device 11 collectively transmits the authority authentication request and the electronic key information link to the second user device 12.
When the electronic key information link is selected, the second user device 12 transmits an authority authentication request to the cloud server 13 in order to cause the cloud server 13 to authenticate the authority authentication request with the information associated with the stored authority authentication. To do. When the content of the authority authentication request is authenticated by the cloud server 13 as appropriate, the cloud server 13 returns an access confirmation to the second user device 12 (S1A). Thus, when the second user receives an access confirmation through the second user device 12, the second user recognizes that the second user device 12 has access rights. Otherwise, if the second user device 12 does not receive an access confirmation, or if the received message is not a notification about the access confirmation, the second user device 12 is not valid for accessing the electronic key. It means that there is.

  After the second user device 12 is authenticated, the second user causes the second user device 12 to transmit the vehicle control signal to the cloud server 13 through the Internet (S15). The vehicle control function is activated on the second user interface 26 (S14). When receiving the vehicle control signal, the cloud server 13 further transmits the vehicle control signal to the vehicle control unit 21 (S15 ').

  When receiving the vehicle control signal transmitted from the cloud server 13, the vehicle control unit 21 outputs the vehicle control signal to control the vehicle operation (S16). Further, the vehicle control unit 21 returns vehicle operation information to the cloud server 13 (S17). After receiving the vehicle operation information, the cloud server 13 returns the vehicle operation information to the second user device 12 (S17 '). A second user who receives vehicle operation information through the second user device 12 can recognize that the vehicle control unit 21 has performed a corresponding control operation on the vehicle 20.

  When returning the vehicle operation information to the second user device 12, the cloud server 13 may transmit a vehicle control notification to the first user device 11 (S18). It is optional and not constrained to allow the first user to recognize what type of control or operational status the vehicle 20 is located by receiving a vehicle control notification.

  Still referring to FIG. FIG. 2B mainly shows that after the cloud server 13 returns an access confirmation to the second user device 12 (S1A) and before the vehicle control function is activated (S14), the cloud server 13 2A is different from FIG. 2A in that a key activation notification is transmitted to the first user device 11 through the Internet when an access confirmation is returned to the user device 12 (S1B). Therefore, by receiving the key activation notification, the first user can recognize that the second user device 12 has completed the authority authentication and becomes a device having the validity of accessing the electronic key.

  Please refer to FIG. The vehicle control function activated in step S14 includes a vehicle position specifying function, a door lock releasing function, and an engine starting function. In other words, when the second user activates the electronic key information link (S13), the second user, depending on the actual situation, the vehicle position specifying function (S141), the door lock release function (S142), Alternatively, the engine start function (S143) is performed.

  When the second user forgets where the vehicle 20 is parked, the vehicle position specifying function (S141) is performed. The second user device 12 transmits a vehicle position request to the cloud server 13 through the Internet (S151). Since the vehicle control unit 21 is always connected to the cloud server 13 through the Internet, the vehicle control unit 21 can continuously transmit this coordinate information to the cloud server 13. As a result, when receiving a vehicle position request, the cloud server 13 transmits vehicle position specifying information to the second user device 12 (S161). Therefore, the second user can acquire coordinate information of the parking position of the vehicle 20.

  Please refer to FIG. The second user interface 26 generated by the second display screen 25 of the second user device 12 can display the position information Pc. In the present embodiment, the position information of the vehicle 20 may be presented in the form of a digital map, but is not limited to this. For example, the position information of the parking position of the vehicle 20 may be indicated using street view information, satellite images, or text.

  Still referring to FIG. When the second user already knows where the vehicle 20 is parked through the vehicle location information or locates the vehicle, the door unlock function (S142) is then performed. The second user device 12 transmits a door lock release signal to the cloud server 13 through the Internet (S152). When receiving the door lock release signal, the cloud server 13 further transmits a door lock release signal to the vehicle control unit (S152 ').

  When receiving the door lock release signal transmitted from the cloud server 13, the vehicle control unit 21 outputs a control signal for unlocking the door of the vehicle 20 (S162). Further, the vehicle control unit returns door lock release operation information to the cloud server 13 (S172). When receiving the door lock release operation information, the cloud server 13 further transmits the door lock release operation information to the second user device 12 (S172 '). Therefore, the second user can recognize that the vehicle control unit 21 has unlocked the door of the vehicle 20 by receiving the door lock release operation information through the second user device 12.

  When returning the door lock release operation information to the second user device 12, it is optional that the cloud server 13 may simultaneously send a door lock release notice to the first user device 11 through the Internet (S182), Not constrained. Therefore, the first user can recognize that the door of the vehicle 20 is controlled by the vehicle control unit 21 such that the door is unlocked.

  When the second user further attempts to start the engine of the vehicle 20, the engine start function (S143) is then performed. The second user device 12 transmits an engine start signal to the cloud server 13 through the Internet (S153). When receiving the engine start signal, the cloud server 13 further transmits the engine start signal to the vehicle control unit 21 (S153 ').

  When receiving the engine start signal transmitted from the cloud server 13, the vehicle control unit 21 further outputs a control signal for controlling the vehicle 20 to start the engine (S163). The vehicle control unit returns engine start operation information to the cloud server 13 (S173). When receiving the engine start operation information, the cloud server 13 further returns the engine start operation information to the second user device 12 (S173 '). Therefore, the second user can recognize that the vehicle control unit 21 has performed a control operation for starting the engine of the vehicle 20 by receiving the engine start operation information.

  When returning the engine start operation information to the second user device 12, the cloud server 13 may transmit the engine start notification simultaneously to the first user device 11 through the Internet (S183). Not. Therefore, the first user can recognize that the engine of the vehicle has been started by the vehicle control unit 21 by receiving the engine start notification.

  The foregoing steps associated with the notification to the first user device 11, such as steps S1B, S18, S182, or S183, are push messages, eg, cloud server 13, Google® cloud messaging (GCM), Apple. The first user device 11 is notified by a push service provided by (registered trademark) push notification service (APNS), Microsoft push notification service (MPNS), or another push server developed by a technician.

  The steps performed by the second user may be performed through the function displayed in FIG. 5A. When the electronic key information link on the second user interface 26 is activated (S13), the vehicle control function shown in FIG. 5A includes a control function 261 and a position specifying function 262. When the second user selects the position specifying function 262, the second user device 12 performs the vehicle position specifying function (S141). The detailed description can refer to FIGS. 3 and 6 and the corresponding description and will not be repeated here.

  When the second user selects the control function 261, the second user interface 26 further provides a lock / engine start function 263 and an unlock / engine stop function 264. When the second user briefly clicks the lock / engine start function 263, the second user device 12 performs the door lock function. The door lock function, which is the basic operation for the vehicle, is therefore not described in detail here. Also, when the second user continues to press the lock / engine start function 263 for a while, the second user device 12 then performs the engine start function S143. The detailed description associated with the engine start function S143 can be referred to FIG. 3 and the corresponding description and will not be repeated here.

  The operation associated with the text input in the comment function 168 is described as follows. After the first user sends the text entered in the comment function 168 to the second user device 12, the second user reads the corresponding text on the second user interface 26 of the second user device 12. It is possible. The second user can further adjust the size of the text displayed on the second user interface 26 by selecting the font size reduction function 265 or the font size increase function 266.

  An open space site, tower parking ground floor, or roadside that allows the vehicle control unit 21 to smoothly connect to the Internet to allow the first user to give the second user access to the vehicle 20 When the vehicle 20 is parked, the vehicle control unit 21 can be directly connected to the cloud server 13 through the Internet. The second user can control the vehicle control unit 21 by connecting to the cloud server 13 through the Internet using the second user device 12.

  In a situation where the vehicle 20 is parked in an underground parking lot where the vehicle control unit 21 cannot be directly connected to the cloud server 13, the second user uses the second user device 12 to drive the vehicle through the cloud server 13. In some cases, the control unit 21 cannot be controlled. In order to deal with this problem, the vehicle control unit 21 can still connect to the second user device 12 by the short-distance connection means, even though the vehicle control unit 21 cannot connect to the cloud server 13 through the Internet. And can be controlled by the second user device 12. The short-distance connection means will be described as follows in conjunction with the corresponding drawings.

Each of the first user device 11, the second user device 12, and the vehicle control unit 21 further has a short-distance connection function. As shown in FIG. 7, the first user device 11 and the second user device 12 can be connected to the vehicle control unit 21 through a short-range connection function. Further, as shown in FIG. 1, the vehicle control unit 21 can be connected to the cloud server 13 in an environment accessible to the Internet.
Specifically, such a short-distance connection function can be implemented by a Bluetooth module according to the Bluetooth (registered trademark) standard. Such a short-range connection function is available when the first user device 11 and the second user device 12 are located with a certain distance between them under a limited distance. In order to facilitate the description of the short-range connection function, the short-range connection can be represented by a Bluetooth connection, but is not limited thereto.

To describe a technical solution for controlling by a short range connection, reference is made to FIGS. The vehicle control unit 21 is incorporated with at least one set of first key information. When the first user device 11 activates the electronic key sharing function (S41A), as shown in FIG. 10A, the first display screen 15 of the first user device 11 displays the first user interface 16A. .
The first user interface 16A has a name associated with an electronic key, along with a Bluetooth control function 171A that allows the second user device 12 to connect to the vehicle control unit 21 and control the vehicle 20 via a Bluetooth connection. Provide electronic key setting functions including setting of effective time, link sharing, activation, and location information. After the electronic key information is set, the first user device 11 sets the electronic key information link so that the second user device 12 obtains the access right for controlling the vehicle according to the electronic key information.
