The in-vehicle core communication interface method of the present invention first performs step S100 (as shown in Figure 4) to send a binding request message: the at least one client 30 and the at least one server 40 connected thereto respectively send a binding request message 31, 41 to the in-vehicle server 20. After completing the above step S100, the next step S110 is performed.

The binding request message 31, 41 (as shown in FIG. 5) contains an identification code (not shown), which is either an identity (ID) or a password or a combination thereof, wherein the identity (ID) of the identification code mainly refers to the identity (ID) of the at least one client 30 or the identity (ID) of the at least one server 40, and the identification code can be a password in addition to the identity (ID), wherein the password of the identification code mainly refers to the single-use code of the at least one client 30 or the at least one server 40, which has its own specificity and cannot be repeated, and can be used to identify the at least one client 30 or the at least one server 40. In addition, it can also be a combination of the identity (ID) and the password to increase its specificity.

In addition, the next step S110 is to log in the inter-program communication interface: when the car server 20 receives the binding request messages 31 and 41 from the at least one client 30 and the at least one server 40, the binding request messages 31 and 41 from the at least one client 30 and the at least one server 40 are respectively logged in the inter-program communication interface 21 of the car server 20. After completing the above step S110, the next step S120 is performed.

The inter-program communication interface 21 has a communication list (LIST) (not shown), and the communication list (LIST) registers the at least one client 30 or the at least one server 40 that sends the binding request message 31, 41, that is, the identification code contained in the binding request message 31, 41 is registered in the communication list (LIST), so that the inter-program communication interface 21 can clearly know who the at least one client 30 or the at least one server 40 to be connected is, and it is also convenient for managing the at least one client 30 or the at least one server 40.

After completing the above step S120, the next step S130 is performed.

The binding completion messages 32 and 42 contain an access right (not shown), which is a CRC verification code, wherein the CRC verification code can be a 15-bit cyclic redundancy check (CRC) field, which can confirm whether the message packet 43 is correct when the at least one message packet 43 is received, so as to ensure that the at least one client 30 has the right to read the message packet 43.

In addition, the next step S130 is for the server to send a message packet: when the at least one server 40 needs to send at least one message packet 43, the at least one message packet 43 contains at least one message identifier (ID) and at least one data message, and the at least one message packet 43 is sent to the car server 20. After completing the above step S130, the next step S140 is performed.

The at least one message identifier (ID) (not shown) mentioned above can be used to determine the priority of different message packets 43, and the at least one client 30 that receives the at least one message packet 43 can also determine whether to process the message packet 43 according to the message identifier (ID), wherein the at least one message identifier (ID) can be 11 bytes or more bytes. The at least one data message (not shown) contains actual data content, and its length can be composed of 0 to 8 bytes, which can be set according to the at least one data message.

Furthermore, the at least one message packet 43 may include the following contents, and the contents are any one of a frame start bit, a remote request (RYR) bit, a control field, a CRC separation bit, an acknowledgment (ACK) bit, an acknowledgment separation bit, a frame end, and a frame interval (not shown). The frame start bit means that when the at least one message packet 43 is sent out, it will be synchronized by the frame start bit first, and the message identifier (ID) and the remote request (RYR) bit will be used to determine the priority of the at least one message packet 43. When the at least two server ends 40 or more server ends 40 send out at least one message packet 43 at the same time, the message identifier (ID) and the remote request (RYR) bit will be used for bitwise arbitration (Bitwise Arbitration) (not shown), and the smallest message packet 43 has its priority and will be sent first. The other server ends 40 will suspend sending the message packet 43 and wait to send the message packet 43 later. The control field has 6 bits, 2 of which are fixed, and the following 4 bits indicate the length of the actual data. The CRC separation bit, ACK bit, and ACK separation bit each have 1 bit for identification. The frame end and frame interval are 7 bits and 2 bits respectively, as the end and confirmation of the message packet 43, so that it has its integrity.

In addition, the next step S140 is to broadcast the message packet: and broadcast the at least one message packet 43 to the at least one client 30 that has completed the login through the inter-program communication interface 21 of the car server 20. After completing the above step S140, the next step S150 is performed.

The above-mentioned car server 20 uses the client 30 listed in the communication list (LIST) of the inter-program communication interface 21 to allow the at least one server 40 to broadcast at least one message packet 43 through the inter-program communication interface 21 in the car server 20, so that the client 30 listed in the communication list (LIST) can receive the at least one message packet 43 sent by the at least one server 40.

In addition, the next step S150 is to determine whether to process the message packet: when the at least one client 30 receives the at least one message packet 43 sent by broadcast, it determines whether to process the at least one message packet 43 according to the message identifier (ID) of the at least one message packet 43. After completing the above step S150, the next step S160 is performed.

In addition, the next step S160 is to perform an action according to the data message: after the at least one client 30 determines to process the at least one message packet 43, it performs an action according to the data message in the at least one message packet 43.

After the at least one client 30 determines that processing is required based on the message identifier (ID) of the at least one message packet 43, it performs actions based on the data information of the at least one message packet 43, such as adjusting the volume, switching songs, shutting down Bluetooth services, etc.

Thus, through the above two vehicle core communication methods, the first vehicle core communication method is that the at least one client 30 is at least one application 50, and the at least one server 40 is at least one interface service 60 (as shown in FIG. 2), and the second vehicle core communication method is that the at least one client 30 is at least one interface service 60, and the at least one server 40 is at least one application 50 (as shown in FIG. 3), so that the vehicle core communication has the performance of two-way communication, and through the vehicle server (car server) 20 is provided with an inter-program communication interface 21, so that the at least one client 30 and the at least one server 40 can communicate through the vehicle server (car The inter-program communication interface 21 in the server) 20 is used for in-vehicle core communication, so that it has the performance of real-time communication and can enhance the ability of in-vehicle management, thereby increasing the overall practicality.

Furthermore, the vehicle core communication interface method of the present invention mainly has two implementation modes, and the first implementation mode (as shown in Figures 4 and 5) includes step S100 sending a binding request message, step S110 logging into the inter-program communication interface, step S120 responding with a binding completion message, step S130 the server sends a message packet, step S140 broadcasting the message packet, step S150 determining whether to process the message packet, and step S160 performing an action according to the data message, which has been described above. Please refer to the above description.

In the second implementation (as shown in FIG. 6 and FIG. 7 ), step S200 sends a binding request message, step S210 logs in to the inter-program communication interface, step S220 responds with a binding completion message, step S250 determines whether to process the message packet, and step S260 performs an action based on the data message, all of which are the same as step S10 in the first implementation. 0 sends a binding request message, step S110 logs in to the inter-program communication interface, step S120 responds to the binding completion message, step S150 determines whether to process the message packet, and step S160 takes action based on the data message. The only difference is that the server sends a message packet in step S230 and the content of the message packet is broadcasted in step S240.

Therefore, the same contents as step S100 sending a binding request message, step S110 logging into the inter-program communication interface, step S120 responding with a binding completion message, step S150 determining whether to process the message packet, and step S160 performing actions according to the data message are not repeated. Please refer to the above description. The following will explain step S230 of the server sending a message packet and step S240 of broadcasting the message packet in the second implementation.

The difference of the second implementation (as shown in FIG. 7) is that the server sends a message packet in step S230: when the at least one server 40 needs to send at least one message packet 43, the at least one message packet 43 contains at least one message identifier (ID) and at least one data message. After completing the above step 230, the next step S240 is performed.

Compared with step S130, the above-mentioned step S230 of the server sending a message packet lacks the step of sending the at least one message packet 43 to the car server 20. The main reason is that the at least one server 40 can first obtain the communication list (LIST) of at least one client 30 in the inter-program communication interface 21 from the car server 20. Therefore, when the at least one server 40 needs to send at least one message packet 43, it does not need to go through the inter-program communication interface 21 of the car server 20.

In addition, the next step is step 240 of broadcasting the message packet: the at least one message packet 43 is directly broadcasted from the at least one server 40 to the at least one client 30.

Compared with the step 140, the step 240 of broadcasting the message packet does not require the at least one message packet 43 to be broadcasted through the inter-program communication interface 21 of the car server 20. Therefore, when the at least one server 40 first obtains the communication list (LIST) containing at least one client 30 in the inter-program communication interface 21 from the car server 20, it can directly broadcast the at least one message packet 43 to the at least one client 30 without going through the inter-program communication interface 21 of the car server 20.

Thus, when the at least one server 40 needs to send at least one message packet 43, there are two implementation methods. The first implementation method is that the at least one message packet 43 is first sent to the car server 20 (as shown in FIG. 5), and then the at least one message packet 43 is broadcasted to the at least one client 30 that has completed the login through the inter-program communication interface 21 of the car server 20. The second implementation method is that the at least one message packet 43 is directly broadcasted from the at least one server 40 to the at least one client 30 (as shown in FIG. 7), so that the server 40 and the client 30 communicate with each other in addition to the communication through the car server. In addition to transmitting the at least one message packet 43 through the inter-program communication interface 21 of the onboard server 20, the server 40 can also directly broadcast the at least one message packet 43 to the client 30 without broadcasting through the inter-program communication interface 21 of the onboard server 20, so as to have different broadcasting performances and thus increase the overall operability.

The above detailed description will enable those familiar with this technology to understand that this invention can indeed achieve the above-mentioned purpose and is in compliance with the provisions of the Patent Law, and therefore an invention patent application is filed.

However, the above is only a preferred embodiment of the present invention, and should not be used to limit the scope of implementation of the present invention; therefore, all simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the invention specification should still fall within the scope of the present invention patent.
