The purpose of automobile diagnosis is to perform performance test and fault detection on an automobile under the condition that the automobile is not disassembled. In general, an automobile is configured with an on-board automatic diagnosis (OnBoardDiagnostics, OBD) system and has an OBD interface matched with the OBD system, and a maintainer can access the OBD interface by using an automobile fault diagnosis instrument to read the diagnosis result of the OBD system so as to find out the fault position and the fault cause of the automobile.
Currently, with the gradual development of automobile diagnosis technology, the automobile diagnosis technology is gradually intelligent, and in order to facilitate the execution of an automobile diagnosis process, generally, the execution of the automobile diagnosis process may refer to fig. 1, which includes: a vehicle 101, a VCI device 102, and a user equipment 103.

However, after the data connection is established between the user equipment 103 and the VCI device 102, the user equipment may only obtain the VCI service through the VCI device 102, and the connection with the external internet cannot be performed, which causes inconvenience in use of the user equipment and affects the use experience of the user to some extent.
In view of the above problems, the present application provides a method for using a VCI device, referring to fig. 2, and one embodiment of the method for using a VCI device of the present application includes: step 201-step 204.
201. And receiving the data signal sent by the user equipment.
The VCI device receives the data signals sent by the user equipment, and is in a use state, namely, is arranged on an OBD interface of the vehicle, and meanwhile, the VCI device can receive the data signals sent by the user equipment through a corresponding communication link for providing services for the user equipment. The VCI device is connected with the user equipment through WIFI, wire or Bluetooth and the like.
202. And judging the type of the data signal.

After the VCI device receives the data signal sent by the user equipment, the attribute of the data signal is judged, and the specific data signal may have a corresponding data identifier for indicating the type of the data signal, such as a vehicle connection interface service request signal or a network service request signal. The general user equipment may wish to acquire network service after establishing a connection with the VCI device, and access to the internet to acquire data of the internet is more, so that a manner of judging whether a vehicle connection interface service request identifier exists for the received data signal may be adopted, if the corresponding identifier exists, the data signal is determined to be the vehicle connection interface service request signal, it may be understood that the type of the data signal is not limited to the vehicle connection interface service request signal or the network service request signal, and more types of data signals may exist in the actual implementation process of the scheme, which is not limited in specific embodiments herein.
203. And selecting a corresponding transmission path and a corresponding transmission destination according to the type of the data signal.
The VCI device determines the type of the data signal and then determines the transmission path and the transmission destination corresponding to the data signal of the type. That is, the data signal transmission process should be performed, and in particular, a transmission path and a transmission destination corresponding to different types of data signals may be preset in the VCI device.
204. And transmitting the data signal to the transmission destination according to the transmission path.
The VCI device transmits the data signal to the transmission destination according to the transmission path. The data signal is described herein as an example of a vehicle connection interface service request signal or a network service request signal.
Further, when the VCI device is network-serviced for the user equipment via a network transmission path; the selecting a corresponding transmission path and a corresponding transmission destination according to the type of the data signal specifically includes:

and sending the network transmission signal to the network server so that the user equipment provides a diagnosis transmission path to realize vehicle diagnosis.
Further, when the VCI device is serving a user equipment network via a diagnostic transmission path; the selecting a corresponding transmission path and a corresponding transmission destination according to the type of the data signal specifically includes:
receiving a diagnosis transmission signal sent by the user equipment;
and sending the diagnosis transmission signal to a vehicle so that the user equipment completes a vehicle diagnosis process through the diagnosis transmission path.
If the data signal belongs to a vehicle connection interface service request signal, the VCI device may determine that the transmission destination is a vehicle electronic control unit, and the transmission path is a circuit connection path between the VCI device and an OBD (On-board diagnostics) connection interface. The VCI device may provide a vehicle connection interface service for the user equipment in dependence of the data signal. Specifically, the VCI device may determine according to a VCI service protocol supported by the VCI device itself, where the service request signal of the vehicle connection interface belongs to a CANBUS protocol or a service request signal of a K-line-based diagnostic protocol, and issue an instruction to the OBD system according to the request signal, so that the OBD system obtains data inside the vehicle ECU and returns corresponding data to the VCI device, and after receiving the data, the VCI device converts the obtained number into a form that can be identified by the user device, and forwards the data to the user device through a data channel, so as to complete a diagnostic process for the vehicle. The specific vehicle connection interface service process is similar to the existing VCI device operation process, and specific reference may be made to the prior art, which is not repeated here.

The VCI device may determine that the transmission destination is a network server, and the transmission path is a network path, and may specifically be a form of wireless network transmission or wired network transmission. At this time, the VCI device starts an AP (wireless access point) mode, on one hand, as a network service receiving terminal, its communication module establishes network connection with a network server through 3G, 4G, 5G, wiFi or even a wired form, and on the other hand, the VCI device acts as a hotspot to share out network service for a user device to connect through WiFi, thereby providing network service for the user device. The specific VCI device may be provided with a network service module for supporting network services, which is similar to a router currently used for providing network services in specific form, and the router first searches a destination address in a routing table, and if the destination address is found, the data signal is transmitted to an output link for output. Since the various network segments and their interconnections may change due to environmental changes, the information of the routing situation is also generally updated regularly as specified by the routing information protocol used. In order to maintain the validity of the routing information. In order to facilitate the transmission of messages between networks, routers always break up larger data into packets of appropriate size according to predetermined rules, and then send out the packets through the same or different paths, respectively. After the data packets arrive at the destination according to the sequence, the decomposed data packets are packaged into the original message form according to a certain sequence. The specific examples are not limited herein.
From the above technical solutions, the embodiment of the present application has the following advantages: according to the scheme, after the VCI device is connected with the user equipment for detection, the type of the data signal sent by the user equipment is judged, a transmission path and a transmission destination are determined according to the type of the data signal, and the data signal is transmitted, so that the user equipment can obtain different kinds of services by sending different types of signals after being connected with the VCI device, and the practicability of the VCI device is improved.

The specific data signal may be a vehicle connection interface service request signal or a network service request signal, and if the type of the data signal is determined to be the network service request signal, step 303 is executed to transmit the data signal to the network server according to the network transmission path. If the type of the data signal is determined to be the vehicle connection interface service request signal, step 304 is executed to transmit the data signal to the vehicle electronic control unit according to the diagnostic transmission path. This step is similar to step 202 in the corresponding embodiment of fig. 2, and is not repeated here.
303. And transmitting the data signal to the network server according to a network transmission path.
The VCI device transmits the data signal to the network server according to the network transmission path. The data signal may be sent to the VCI device by the user equipment through any one of WIFI connection, bluetooth connection, or wired connection, and the network transmission path is any one or more of wired network transmission, 4G network transmission, or 5G network transmission. Specific data transmission process referring to fig. 4, a data signal is transmitted from a user equipment 403 to a VCI device 402, and then transmitted from the VCI device 402 to a network server 404.
And if the data signal is a network service request signal, the VCI device provides network service for the user equipment according to the data signal. The specific network service may be: a 4G (the 4thgeneration mobilecommunicationtechnology, fourth Generation mobile communication technology) network service or a 5G (5 th-Generation, fifth Generation mobile communication technology) network service. The VCI may perform functions with an existing 4G router or 5G router, that is, use a wireless network or a wireless network access chip (SIM card) provided by a wireless carrier as a network source, on the basis of which a WIFI hotspot sharing network is established, a specific VCI device may be provided with a card slot for accommodating a SIM card, and after receiving a data signal for requesting network services sent by a user device through a WIFI link, the identity information of the SIM card may be added to the data signal and forwarded to a base station supporting the 4G network or 5G network, so as to provide network services for the user device, and a specific form may refer to an operation mode of the current 4G router or 5G router, which is not limited herein.
304. The data signal is transmitted to the vehicle electronic control unit according to the diagnostic transmission path.
The VCI device transmits the data signal to the vehicle electronic control unit in accordance with the diagnostic transmission path. The diagnosis transmission path is transmitted through an on-board diagnosis system interface, and the data signal can be sent to the VCI device by the user equipment through any one of WIFI connection, bluetooth connection or wired connection. Referring specifically to fig. 4, data signals are transmitted by the user equipment 403 to the VCI device 402 and then transmitted by the VCI device 402 to the vehicle 401.
And if the data signal is a vehicle connection interface service request signal, the VCI device provides vehicle connection interface service for the user equipment according to the data signal. Specifically, the protocol type of the vehicle connection interface service may be: any one or more of interface service protocol (CANBus, controLLerAreaNet-workbench), internet protocol based diagnostic communication (DoIP, diagnostic communicationoverInternetProtocol), K-wire based diagnostic protocol based on a serial bus system.

In the practical implementation process, the staff may make appropriate adjustments to the protocol types supported by the VCI device according to the practical situation, which is not limited herein. For the VCI devices belonging to different types of diagnosis protocols, the VCI devices convert the diagnosis protocols into instructions which can be recognized and executed by the vehicle OBD system according to the protocols, after the instructions are executed, execution results are returned to the VCI devices and are converted by the VCI devices, the converted results are data which can be recognized by the user equipment, namely, diagnosis data, and the user equipment can diagnose the current specific conditions of the vehicle after receiving the returned diagnosis data.
Notably, in this scenario, the VCI device supports the DoIP diagnostic protocol, defined by the ISO13400 series of standards, as a solution for implementing Ethernet-based diagnostic communications. When the DoIP diagnosis protocol is used for diagnosing the vehicle, the VCI device only bears the forwarding work of instructions and data and does not process the transmitted data, so that the user equipment can be considered to be directly communicated with the vehicle under the condition of the DoIP protocol, and the VCI device only plays a role in establishing the connection function between the vehicle and the user equipment, so that the advantages of the DoIP have the following points: faster diagnostic response, shorter time to transmit large amounts of data and enable remote direct diagnostics.
