The purpose of automobile diagnosis is to perform performance test and fault detection on an automobile without disassembling the automobile. Generally, an automobile is provided with an on-board diagnostic (OBD) system and an OBD interface matched with the OBD system, so that a maintenance worker can access the OBD interface by using an automobile fault diagnosis instrument to read a diagnosis result of the OBD system, so as to find out a fault part and a fault reason of the automobile.
At present, with the gradual development of the automobile diagnosis technology, the automobile diagnosis technology is gradually intelligentized, and in order to facilitate the execution of the 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 user equipment 103.
Wherein the vehicle 101 has an OBD system for automatic diagnosis of the vehicle and an OBD interface for reading vehicle data in the OBD system.
The VCI device 102 is configured to obtain data in the vehicle, and when the VCI device is used, the VCI device needs to be connected to an OBD interface on the vehicle, so as to interact with an OBD system of the vehicle to obtain corresponding data. The specific VCI device can support a serial bus system (CANBus) or other K-line-based diagnostic protocols, receives an instruction sent by user equipment, converts the instruction into an instruction executable by an OBD system, executes the instruction and returns corresponding data to the VCI device, and then converts the corresponding data and sends the converted data to the user equipment so as to complete data reading of a vehicle and diagnose the vehicle.
The user device 103 is a device used by a user, and establishes a connection with the VCI apparatus through wireless fidelity (WIFI), bluetooth, or wire, and the like, and the user device includes but is not limited to a smart phone, a tablet computer, a laptop portable computer, a desktop computer, a self-service terminal, and a wearable electronic device. In order to implement the detection of the vehicle, the user equipment may be correspondingly provided with diagnostic software, an application program, or an APP that is used in cooperation with the VCI apparatus, so that the user may use the interactive function of the user equipment 103 to send a corresponding diagnostic instruction through a WIFI data transmission path established between the user equipment 103 and the VCI apparatus 102, and then the VCI apparatus may execute a corresponding data reading or diagnostic process and return a processing result to the user equipment.
However, after the data connection is established between the user equipment 103 and the VCI device 102, the user equipment can only obtain the VCI service through the VCI device 102, but cannot be connected to the external internet, which causes inconvenience in use of the user equipment and certain influence on the use experience of the user.
In view of the above problems, the present application provides a method for using a VCI apparatus, and referring to fig. 2, an embodiment of the method for using a VCI apparatus of the present application includes: step 201-step 204.
201. And receiving a data signal sent by the user equipment.
The VCI device receives the data signal sent by the user equipment, and is in a use state, that is, is disposed on an OBD interface of the vehicle, and simultaneously, the VCI device has established a corresponding data connection with the user equipment, and can receive the data signal sent by the user equipment through a corresponding communication link, so as to provide a service for the user equipment. The VCI device is connected with the user equipment in a WIFI, wired or Bluetooth mode and the like.
202. And judging the type of the data signal.
The VCI device judges the type of the data signal after receiving the data signal. After receiving the data signal sent by the user equipment, the VCI device determines the attribute of the data signal, where 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 wants to acquire network service after establishing connection with the VCI device, and accesses the internet to acquire data of the internet, so a manner of judging whether a vehicle connection interface service request identifier exists for a received data signal can be adopted, if so, the data signal is determined to be a vehicle connection interface service request signal, it can 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 of different types can exist in the actual implementation process of the scheme, and the specific details are not limited herein.
203. And selecting a corresponding transmission path and a transmission destination according to the type of the data signal.
After determining the type of the data signal, the VCI device determines a transmission path and a transmission destination corresponding to the data signal of the type. That is, the data signal transmission process should be executed, and in particular, the transmission path and the transmission destination corresponding to different types of data signals may be preset in the VCI apparatus.
204. And transmitting the data signal to the transmission destination according to the transmission path.
And the VCI device transmits the data signal to the transmission destination according to the transmission path. Here, the data signal is taken as a vehicle connection interface service request signal or a network service request signal as an example for explanation.
Furthermore, when the VCI device is used for network service of user equipment through a network transmission path; the selecting a corresponding transmission path and a transmission destination according to the type of the data signal specifically includes:
receiving a network transmission signal sent by the user equipment;
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 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 the vehicle connection interface service request signal, the VCI device can 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 can provide vehicle connection interface service for the user equipment according to the data signal. Specifically, the VCI device may perform a determination according to a VCI service protocol supported by the VCI device, where the vehicle connection interface service request signal belongs to a CANBUS protocol or a service request signal of a diagnostic protocol based on a K-line, 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 the VCI device converts the obtained data into a form that can be recognized by the user equipment after receiving the data, and forwards the data to the user equipment through a data channel to complete a vehicle diagnostic process. The specific vehicle connection interface service process is similar to the working process of the existing VCI device, and reference may be made to the prior art specifically, which is not described herein again.
If the data signal belongs to the network service request signal. The VCI apparatus may determine that the transmission destination is a network server, and the transmission path is a network path, which may be in 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, the VCI device serves as a network service receiving terminal, a communication module of the VCI device establishes network connection with a network server through 3G, 4G, 5G, WiFi or even in a wired manner, and on the other hand, the VCI device serves as a hotspot to share out network services for the user equipment to connect through WiFi, thereby providing network services for the user equipment. The specific VCI apparatus may be correspondingly configured with a network service module for supporting the network service, and the specific form is similar to that of the router currently used for providing the network service, and the router first searches for a destination address in the routing table, and if the destination address is found, transmits the data signal to the output link for output. Since various network segments and their interconnections may change due to environmental changes, the routing information is also typically updated periodically 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 these packets through the same or different paths, respectively. When the data packets arrive at the destination in order, the decomposed data packets are packed into the original message form according to a certain order. The details are not limited herein.
According to the technical scheme, the embodiment of the 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, the transmission path and the 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 types of services by sending different types of signals after being connected with the VCI device, and the practicability of the VCI device is improved.

One feasible way is to find the hot spot opened by the VCI device through the WIFI search function of the user equipment, send a connection request to the hot spot, and send a corresponding data signal to the VCI device after the connection is established. The VCI device may provide a VCI diagnostic function when installed on the vehicle, and the VCI device may be powered by the vehicle to support network services and diagnostic services, which is not limited herein. This step is similar to step 201 in the embodiment corresponding to fig. 2, and is not described here again.
302. And judging the type of the data signal.
The VCI device determines the type of the data signal. 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 a 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 diagnosis transmission path. This step is similar to step 202 in the corresponding embodiment of fig. 2, and is not described here again.
303. And transmitting the data signal to the network server according to a network transmission path.
And the VCI device transmits the data signal to the network server according to the network transmission path. The data signal can be sent to the VCI device by the user equipment through any one of a WIFI connection, a bluetooth connection, or a wired connection, and the network transmission path is any one or more of wired network transmission, 4G network transmission, or 5G network transmission. Referring to fig. 4, a data signal is transmitted from the user equipment 403 to the VCI apparatus 402, and then transmitted from the VCI apparatus 402 to the 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 (the4th Generation mobile communication technology) network service or a 5G (5th-Generation, fifth Generation mobile communication technology) network service. The VCI may function as an existing 4G router or 5G router, that is, a wired network or a wireless internet chip (SIM card) provided by a wireless operator is used as a network source, on the basis of which a WIFI hotspot sharing network is established, a card slot for accommodating a SIM card may be disposed on a specific VCI device, and after receiving a data signal requesting network service sent by the user equipment 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 service for the user equipment.
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 according to the diagnosis transmission path. The diagnosis transmission path is transmitted through an interface of the vehicle-mounted diagnosis system, and the data signals can be sent to the VCI device by the user equipment through any one of a WIFI connection mode, a Bluetooth connection mode or a wired connection mode. Specifically, referring to fig. 4, the data signal is transmitted from the user equipment 403 to the VCI device 402, and then transmitted from 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 a serial bus system-based interface service protocol (CANBus), an internet protocol-based Diagnostic communication (DoIP), and a K-wire-based Diagnostic protocol. The specific type of the protocol may be any one or more of DoIP, ISO15765, ISO14230, ISO9142-2, SAEJ1708, SAEJ1850, SAE2610, SAEJ2411, SAEJ2740 and SAEJ2809 protocols, and it is to be understood that the type of protocol listed here is not a limitation on the type of protocol supported by the method. In an actual implementation process, the staff may appropriately adjust the protocol type supported by the VCI device according to the actual situation, which is not limited herein. The VCI device belonging to different diagnostic protocols can convert the VCI device into an instruction which can be identified and executed by the OBD system of the vehicle according to the protocol, and returns an execution result to the VCI device after execution and is converted by the VCI device, the converted result is data which can be identified by the user equipment, namely diagnostic data, and the user equipment can diagnose the current specific situation of the vehicle after receiving the returned diagnostic data.
It is noted that, in the implementation scenario of the present solution, the VCI apparatus supports a DoIP diagnostic protocol, where DoIP is defined by ISO13400 series standards, as a scheme for implementing diagnostic communication based on Ethernet. When the vehicle is diagnosed by using the DoIP diagnostic protocol, the VCI device only undertakes the forwarding work of the instruction and the 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 a connection function between the vehicle and the user equipment, so that the DoIP has the following advantages: faster diagnostic response, shorter time to transmit large amounts of data and enable remote direct diagnosis.
305. And transmitting the diagnosis data to the user equipment so that the user equipment acquires network service to complete the diagnosis process of the vehicle.
And the VCI equipment transmits the diagnosis data to the user equipment so that the user equipment acquires network service to finish the diagnosis process of the vehicle. The diagnostic data is data that the ECU returns to the VCI device upon request by the user equipment. After receiving the diagnostic data, the user equipment may also need to use a network service to complete a diagnostic process, and in this process, the network transmission function provided by the VCI device may be used to obtain the network service, and may also be connected to other third-party network equipment to obtain the network service, which is not limited herein.
