Technical Field

The application belongs to the technical field of automotive electronics, and particularly relates to a vehicle remote diagnosis method, device, connector and storage medium.

Background

With the popularization of vehicles and the development of communication technology, when the vehicle is diagnosed, the diagnosis can be performed remotely. The remote diagnosis of the vehicle generally comprises the steps that a first joint serving as a client is inserted into a target vehicle, and data are interacted between a central processing unit of the first joint and a single chip microcomputer through a serial port between the central processing unit and the single chip microcomputer; a second connector as a server is inserted on the diagnostic instrument, and data are exchanged between the central processing unit of the second connector and the singlechip through serial ports between the central processing unit and the singlechip; the first joint and the second joint interact data through the cloud platform, and the diagnosis process is completed. When the serial port between the central processing unit of the first joint or the second joint and the singlechip exchanges data, the speed of the bus in the target vehicle is not considered. Once the vehicle plugged in the first connector is not the previous target vehicle, it means that the bus rate of the vehicle may change, and thus, when the serial port still uses the original data rate, the data may be lost during transmission.

Currently, in a vehicle remote diagnosis method, a vehicle connector reads vehicle information through a vehicle bus, then data is transmitted to a diagnosis connector through a server, and the diagnosis connector transmits the data to a diagnosis device, so that remote diagnosis is realized. However, a problem of untimely transmission occurs when the communication protocol employed by the vehicle uses a data transmission rate that is not compatible with the vehicle connector or the diagnostic connector. At present, aiming at untimely transmission, two main solutions are provided, one is to increase the buffer area of the MCU of the joint, however, on one hand, the MCU usually has no large memory space, so the space for increasing the buffer area is limited, and when continuous big data still can cause data loss; on the other hand, even if the buffer is large enough, the data cannot be buffered in time for forwarding through the serial port in the future, but still causes data delay, and remote diagnosis has a high requirement on data delay, which usually cannot exceed 50 milliseconds, so that the remote diagnosis fails due to the delay even if data is not lost. The other method is to improve the baud rate of the serial port, although the method can solve the problems of data loss and transmission delay, on one hand, the higher the rate is, the higher the error rate is, the worse the anti-interference capability is, and the worse the power supply environment of the vehicle is, the more easily interfered; on the other hand, when the baud rate of the serial port is increased, if the bus of the vehicle does not support the increased baud rate, the remote diagnosis may fail due to the increase of the bit error rate, and therefore, it is not preferable to increase the baud rate of the serial port at once.

In view of the above problems in the prior art, the present application provides a method and an apparatus for vehicle remote diagnosis, an electronic device, and a storage medium, so that a serial port can adapt to the rates of different buses.

Fig. 1-a illustrates a vehicle remote diagnosis method provided in an embodiment of the present application, which is applicable to the vehicle remote diagnosis system illustrated in fig. 1-b, wherein the vehicle remote diagnosis system includes a diagnosis device 101, a diagnosis connector 102, and a vehicle connector 103, the diagnosis device 101 is communicatively connected to the diagnosis connector 102, the vehicle connector 103 is communicatively connected to a vehicle 104 to be diagnosed, and the vehicle connector 103 and the diagnosis connector 102 can communicate via a network 105, for example, a cloud server. The method illustrated in fig. 1-a mainly comprises steps S101 to S106, which are explained as follows:

step S101: a communication connection of the vehicle connector with the diagnostic connector is established.

In the embodiment of the present application, the communication connection between the vehicle connector and the diagnostic connector may be performed through the network illustrated in fig. 1-b, firstly, the vehicle connector and a server (cloud server) of the network establish the communication connection through two or three handshakes, and secondly, the diagnostic connector and the server of the network also establish the communication connection through two or three handshakes, so as to establish the communication connection between the vehicle connector and the diagnostic connector.

Step S102: the vehicle connector acquires vehicle information of a vehicle to be diagnosed.

The vehicle connector acquires vehicle information of the vehicle to be diagnosed including vehicle type information and/or vehicle bus configuration information of the vehicle to be diagnosed, and the like.

Step S103: the vehicle connector determines target configuration information from the vehicle information.

In this embodiment of the application, the target configuration information may be a download path of a configuration file corresponding to the vehicle type information, or a configuration file generated according to the vehicle bus configuration information.

Step S104: the vehicle connector notifies the diagnostic connector of the target configuration information.

The vehicle connector notifies the diagnosis connector of the target configuration information mainly comprises two situations of direct notification and indirect notification, wherein the direct notification means that the vehicle connector directly sends the target configuration information to the diagnosis connector, and the indirect notification means that the vehicle connector sends the vehicle information to a server on a network side, and the server inquires the corresponding target configuration information and then sends the target configuration information to the diagnosis connector or the diagnosis connector downloads the target configuration information from the server.

Step S105: the vehicle connector and the diagnostic connector perform baud rate configuration according to the target configuration information.

Specifically, on the side of the vehicle connector, when a target vehicle bus protocol is consistent with a bus protocol preset by the vehicle connector, carrying out baud rate configuration according to a baud rate corresponding to the bus protocol preset by the vehicle connector, otherwise, carrying out baud rate configuration according to a target baud rate corresponding to the target vehicle bus protocol; on the side of the diagnosis connector, when the bus protocol of the target vehicle is consistent with the bus protocol preset by the diagnosis connector, carrying out baud rate configuration according to the baud rate corresponding to the bus protocol preset by the diagnosis connector, otherwise, carrying out baud rate configuration according to the target baud rate corresponding to the bus protocol of the target vehicle.

Step S106: and the vehicle remote diagnosis system diagnoses the vehicle to be diagnosed according to the configured baud rate.

Specifically, the step S106 may be implemented by the diagnostic device sending a diagnostic instruction to the diagnostic connector, the diagnostic connector transmitting the diagnostic instruction to the vehicle connector through remote communication, the vehicle connector reading vehicle data of the vehicle to be diagnosed according to the diagnostic instruction and then feeding the vehicle data back to the diagnostic connector through remote communication, the diagnostic connector feeding back to the diagnostic device, the diagnostic device analyzing the vehicle data and obtaining a diagnostic result, and the diagnostic result may be fed back to the side of the vehicle connector through communication connection between the vehicle connector and the diagnostic connector.

As can be seen from the above-mentioned technical solutions illustrated in fig. 1-a, after determining the target configuration information according to the vehicle information, on one hand, the target configuration information is notified to the diagnostic connector so as to configure the baud rate according to the target configuration information, and on the other hand, the vehicle connector also configures the baud rate according to the target configuration information, in other words, the transmission rate of the serial port between the central processor of the vehicle connector or the diagnostic connector and the single chip microcomputer can always match the rate that can be supported by the bus of the target vehicle, so when the bus type of the vehicle changes, the transmission rate of the serial port between the central processor of the vehicle connector or the diagnostic connector and the single chip microcomputer will match the rate that is supported by the changed bus type, so that the serial port can adapt to the rates of different buses, that is, the serial port can be adjusted to different transmission rates according to different bus types, thereby avoiding the problems of the prior art.

Fig. 2 illustrates a vehicle remote diagnosis method provided by the embodiment of the application, which is applicable to a vehicle connector, and the vehicle connector is in communication connection with a vehicle to be diagnosed. The vehicle remote diagnosis method illustrated in fig. 2 mainly includes steps S201 to S206, which are explained as follows:

step S201: a communication connection is established with a diagnostic connector, wherein the diagnostic connector is in communication with the diagnostic device.

Before or during the communication connection with the diagnostic connector, the microcontroller of the vehicle connector may be reset, and the serial port is set to the default transmission rate, where the serial port is a data transmission interface between the central processing unit of the vehicle connector and the microcontroller. The reason for setting the serial port, namely the data transmission interface between the central processing unit of the vehicle connector and the microcontroller, as the default transmission rate is to consider that the rate of the bus of most vehicles, such as a CAN bus, is matched with the default transmission rate, or a large amount of data is not transmitted before the remote diagnosis is started, so that the command for configuring the vehicle CAN be ensured to be reliable by setting the serial port as the default transmission rate, and the user experience is not influenced. As for the method for resetting the microcontroller of the vehicle connector, the method may specifically be to pull the reset pin of the microprocessor to a low level, keep the low level for a period of time, then pull the reset pin of the microprocessor to a high level, and finally set the serial port to a default transmission rate, for example, a rate matching with a conventional CAN bus of the vehicle. It should be noted that the default serial port transmission rate set here may be a default baud rate.

As for establishing the communication connection with the diagnostic connector, in the embodiment of the present application, the communication connection may be an indirect communication connection or a direct communication connection, where the indirect communication connection includes a communication connection established through a server (a physical server or a cloud server), data interaction between the vehicle diagnostic device and the diagnostic connector is performed through the server, and the direct communication connection does not have a relay device between the vehicle diagnostic device and the diagnostic connector, but directly interacts in a Peer-to-Peer (P2P) communication manner. On the other hand, if the communication connection between the vehicle diagnostic device and the diagnostic connector is described from the perspective of connection, both may be wired networks or wireless networks, including mobile communication networks such as 4G, 5G, or 6G.

Step S202: vehicle information of a vehicle to be diagnosed is acquired.

In the embodiment of the present application, the vehicle information of the vehicle to be diagnosed mainly includes vehicle type information of the vehicle to be diagnosed or vehicle bus configuration information of the vehicle to be diagnosed, and the like, where the vehicle type information of the vehicle to be diagnosed mainly refers to what vehicle type the vehicle to be diagnosed belongs to, and the vehicle bus configuration information of the vehicle to be diagnosed mainly includes bus types supported by the vehicle to be diagnosed, for example, a high-speed CAN bus, a medium-speed CAN bus, a low-speed CAN bus, and/or a CAN FD bus, and the like. One method of acquiring vehicle information of a vehicle to be diagnosed may be: analyzing a Vehicle Identification Number (VIN) of a Vehicle Electronic Control Unit (ECU) to be diagnosed to determine Vehicle type information of the Vehicle to be diagnosed; and determining whether a communication protocol of the vehicle supports a CAN bus or a CAN FD bus according to the vehicle type information of the vehicle to be diagnosed, wherein if the CAN bus is supported, communication attempts with the vehicle to be diagnosed at different speeds are carried out through a vehicle connector, for example, 250k, 500k, 125k or 1M (the unit is bit/s), and after the communication attempts are normal, whether the corresponding CAN bus is a high-speed CAN bus, a medium-speed CAN bus or a low-speed CAN bus is determined.

Step S203: target configuration information is determined based on the vehicle information.

As described above, the vehicle information includes the model information of the vehicle to be diagnosed or the vehicle bus configuration information of the vehicle to be diagnosed. When the vehicle information is the vehicle type information of the vehicle to be diagnosed, as an embodiment of the present application, determining the target configuration information according to the vehicle information may be: sending the vehicle type information to a server so that the server searches a configuration file corresponding to the vehicle type information in a preset vehicle type configuration file database according to the vehicle type information; and determining a download path of the configuration file corresponding to the vehicle type information as target configuration information. Obviously, in the above embodiment, the server has pre-stored the configuration file corresponding to the vehicle type information, so that the server can search the configuration file corresponding to the vehicle type information in the preset vehicle type configuration file database according to the vehicle type information sent by the vehicle connector.

When the vehicle information is the vehicle bus configuration information of the vehicle to be diagnosed, as another embodiment of the present application, the determining the target configuration information according to the vehicle information may be: generating a configuration file according to the vehicle bus configuration information; and determining the generated configuration file as target configuration information. Different from the foregoing embodiment, in this embodiment, the server does not pre-store the configuration file corresponding to the vehicle type information, so that the vehicle bus configuration information of the vehicle to be diagnosed can only be read by the vehicle connector, then the configuration file is generated according to the vehicle bus configuration information of the vehicle to be diagnosed, and finally, the generated configuration file is determined as the target configuration information.

Step S204: and informing the target configuration information to the diagnosis connector so that the diagnosis connector carries out baud rate configuration according to the target configuration information.

In the embodiment of the application, the informing of the target configuration information to the diagnosis connector mainly includes two situations, namely direct informing and indirect informing, wherein the direct informing means that the vehicle connector directly sends the target configuration information to the diagnosis connector, the indirect informing means that the vehicle connector sends the vehicle information to a server on a network side, the server queries a configuration file corresponding to the vehicle type information in a preset vehicle type configuration file database according to the vehicle type information, determines the target configuration information and then sends the target configuration information to the diagnosis connector or the diagnosis connector downloads the target configuration information from the server, and the diagnosis connector performs baud rate configuration according to the target configuration information.

Step S205: and carrying out baud rate configuration according to the target configuration information.

Different from the prior art that the transmission rate of a serial port (a data transmission interface between a central processing unit of a diagnosis connector or a vehicle connector and a microcontroller) is improved uniformly, so that the error rate is improved, the technical scheme of the application does not improve the transmission rate of the serial port uniformly, but performs baud rate configuration according to target configuration information, and sets the transmission rate of the serial port to be the rate corresponding to bus configuration information of a vehicle to be diagnosed. Therefore, when the transmission rate of the serial port does not need to be increased or the bus of the vehicle to be diagnosed is matched with the default transmission rate of the serial port, the error rate caused by the increase of the transmission rate of the serial port can be avoided.

Specifically, as an embodiment of the present application, the performing baud rate configuration according to the target configuration information may be: determining a target configuration file according to the target configuration information; analyzing the target configuration file to obtain a target vehicle bus protocol; judging whether a bus protocol of the target vehicle is consistent with a bus protocol preset by a vehicle connector; if the bus protocol is consistent with the bus protocol preset by the vehicle connector, carrying out baud rate configuration according to the baud rate corresponding to the bus protocol preset by the vehicle connector; and if the bus rate is inconsistent with the target bus rate, carrying out baud rate configuration according to the target baud rate corresponding to the target bus protocol. For example, if the bus type supported by the target vehicle bus protocol is a CAN bus, the transmission rate of the serial port is kept as the default transmission rate; and if the bus type supported by the target vehicle bus protocol is the CAN FD bus, switching the transmission rate of the serial port to the transmission rate corresponding to the CAN FD bus through the interaction between the central processing unit of the vehicle connector and the microcontroller. It should be noted here that even if the bus type supported by the target vehicle bus protocol is a CAN bus, since the CAN bus further includes a high-speed CAN bus, a medium-speed CAN bus or a low-speed CAN bus, when the bus type supported by the target vehicle bus protocol is a CAN bus, communication attempts at different speeds, for example, 250k, 500k, 125k or 1M (the unit is bit/s) are performed with the vehicle to be diagnosed through the vehicle connector, and when the communication attempts are normal, it is determined whether the corresponding CAN bus is the high-speed CAN bus, the medium-speed CAN bus or the low-speed CAN bus. In the above embodiment, the baud rate configuration according to the baud rate corresponding to the target vehicle bus protocol may specifically be: judging whether the vehicle connector supports the target baud rate or not; if so, carrying out baud rate configuration according to the target baud rate; if not, returning failure information. Specifically, a rate switch command may be sent to the microcontroller through the central processor of the vehicle connector; and if the confirmation response returned by the microcontroller is received, the transmission rate of the serial port between the central processing unit and the microcontroller is switched to the transmission rate corresponding to the CAN FD bus through the central processing unit. After confirming that the bus type supported by the target vehicle is the CAN FD bus, the central processing unit sends a speed switching command to the microcontroller, and then waits for the response of the microcontroller. If the microcontroller supports the transmission rate to be switched, namely the transmission rate corresponding to the CAN FD bus, the transmission rate of the serial port is switched to the transmission rate corresponding to the CAN FD bus, meanwhile, a confirmation response is returned to the microcontroller, the confirmation response indicates that the microcontroller supports the transmission rate corresponding to the CAN FD bus and successfully switches the transmission rate of the serial port to the transmission rate corresponding to the CAN FD bus, and otherwise, a failure response indicates that the microcontroller does not support the transmission rate corresponding to the CAN FD bus and/or does not switch the transmission rate of the serial port to the transmission rate corresponding to the CAN FD bus. And the central processing unit receives the confirmation response returned by the microcontroller, and switches the transmission rate of the serial port to the transmission rate corresponding to the CAN FD bus.

Step S206: and diagnosing the vehicle to be diagnosed according to the configured baud rate.

Specifically, the diagnostic device may send diagnostic instructions to the diagnostic connector at the configured baud rate, and the diagnostic connector transmits the diagnostic instructions to the vehicle connector via remote communication. And after reading the vehicle data of the vehicle to be diagnosed according to the diagnosis instruction, the vehicle connector feeds the vehicle data back to the diagnosis connector through remote communication according to the configured baud rate, the diagnosis connector feeds back the vehicle data to the diagnosis equipment, the diagnosis equipment analyzes the vehicle data and obtains a diagnosis result, and the diagnosis result can be fed back to one side of the vehicle connector through the communication connection between the vehicle connector and the diagnosis connector.

As can be seen from the vehicle remote diagnosis method illustrated in fig. 2, after the target configuration information is determined according to the vehicle information, on one hand, the target configuration information is notified to the diagnosis connector to configure the baud rate according to the target configuration information, and on the other hand, the vehicle connector also configures the baud rate according to the target configuration information, in other words, the transmission rate of the serial port between the central processing unit of the vehicle connector or the diagnosis connector and the single chip microcomputer can always match with the rate that can be supported by the bus of the target vehicle, so when the bus type of the vehicle changes, the transmission rate of the serial port between the central processing unit of the vehicle connector or the diagnosis connector and the single chip microcomputer matches with the rate that is supported by the changed bus type, so that the serial port can adapt to the rates of different buses, that is, the serial port can be adjusted to different transmission rates according to different bus types, thereby avoiding the problems of the prior art.

Fig. 3 illustrates a vehicle remote diagnosis method provided in another embodiment of the present application, which is applicable to a diagnosis connector, the diagnosis connector being communicatively connected to a diagnosis device, and the method includes steps S301 to S304, which are described in detail as follows:

step S301: and establishing a communication connection with a vehicle connector, wherein the vehicle connector is in communication connection with the vehicle to be diagnosed.

Similar to the previous embodiment, before or while establishing the communication connection with the vehicle connector, the microcontroller of the diagnostic connector may be reset, setting the serial port as the default transmission rate, wherein the serial port is the data transmission interface between the central processor of the diagnostic connector and the microcontroller. The reason for setting the serial port, i.e., the data transmission interface between the central processing unit of the diagnostic connector and the microcontroller, as the default transmission rate is to consider that the rate of the bus of most vehicles, such as a CAN bus, is matched with the default transmission rate, or a large amount of data is not transmitted before the remote diagnosis is started, so that the command for configuring the vehicle CAN be ensured to be reliable by setting the serial port as the default transmission rate, and the user experience is not influenced. As for the method of resetting the microcontroller of the diagnostic connector, the reset pin of the microprocessor may be first pulled to a low level, the low level is maintained for a period of time, then the reset pin of the microprocessor is pulled to a high level, and finally the serial port is set to a default transmission rate, for example, a rate matching the conventional CAN bus of the vehicle. It should be noted that the default serial port transmission rate set here may be a default baud rate. In addition, the communication connection established with the vehicle connector may be an indirect communication connection or a direct communication connection, wherein the indirect communication connection includes a communication connection established through a server (a physical server or a cloud server), data interaction between the diagnosis connector and the vehicle diagnostic device is performed through the server, and the direct communication connection has no relay equipment between the diagnosis connector and the vehicle diagnostic device, but directly interacts in a P2P communication manner. On the other hand, if the communication connection between the diagnostic connector and the vehicle diagnostic device is described from the perspective of connection, the two may be wired networks or wireless networks, including mobile communication networks such as 4G, 5G, or 6G.

Step S302: and acquiring the notification of the vehicle connector, wherein the notification of the vehicle connector comprises target configuration information, the target configuration information is determined by the vehicle connector according to the vehicle information, and the vehicle information is acquired by the vehicle connector from the vehicle to be diagnosed.

In the embodiment of the application, the method for acquiring the notification of the vehicle connector by the diagnosis connector mainly comprises a direct mode and an indirect mode, wherein the direct mode is that the vehicle connector directly sends the target configuration information, the diagnosis connector receives the target configuration information, and the indirect mode is that the server notifies the diagnosis connector, and the diagnosis connector downloads the target configuration information from the server or the server sends the target configuration information to the diagnosis connector. It should be noted that the target configuration information includes a download path of the target configuration file or the target configuration file.

Step S303: and carrying out baud rate configuration according to the target configuration information.

As previously mentioned, the target configuration information includes a download path of the target configuration file or the target configuration file. When the target configuration information is a download path of the target configuration file, as an embodiment of the present application, performing baud rate configuration according to the target configuration information may be: downloading the target configuration file according to the download path of the target configuration file; analyzing the target configuration file to obtain a target vehicle bus protocol; judging whether the bus protocol of the target vehicle is consistent with the bus protocol preset by the diagnosis connector; if the bus protocol is consistent with the preset bus protocol, carrying out baud rate configuration according to the baud rate corresponding to the bus protocol preset by the diagnosis connector; and if the bus rate is inconsistent with the target bus rate, carrying out baud rate configuration according to the target baud rate corresponding to the target bus protocol. When the target configuration information is the target configuration file, as another embodiment of the present application, the performing baud rate configuration according to the target configuration information may be: analyzing the target configuration file to obtain a target vehicle bus protocol; judging whether the bus protocol of the target vehicle is consistent with the bus protocol preset by the diagnosis connector; if the bus protocol is consistent with the preset bus protocol, carrying out baud rate configuration according to the baud rate corresponding to the bus protocol preset by the diagnosis connector; and if the bus rate is inconsistent with the target bus rate, carrying out baud rate configuration according to the target baud rate corresponding to the target bus protocol. For example, if the bus type supported by the bus protocol of the target vehicle is a CAN bus, the transmission rate of a serial port (a data transmission interface between a central processing unit of the diagnostic connector and a microcontroller) is kept as a default transmission rate; and if the bus type supported by the bus protocol of the target vehicle is the CAN FD bus, switching the transmission rate of the serial port of the diagnostic connector to the transmission rate corresponding to the CAN FD bus through the interaction between the central processing unit of the diagnostic connector and the microcontroller. .

Step S304: and diagnosing the vehicle to be diagnosed according to the configured baud rate.

As can be seen from the vehicle remote diagnosis method illustrated in fig. 3, after the target configuration information is determined according to the vehicle information, on one hand, the target configuration information is notified to the diagnosis connector to configure the baud rate according to the target configuration information, and on the other hand, the vehicle connector also configures the baud rate according to the target configuration information, in other words, the transmission rate of the serial port between the central processing unit of the vehicle connector or the diagnosis connector and the single chip microcomputer can always match with the rate that can be supported by the bus of the target vehicle, so when the bus type of the vehicle changes, the transmission rate of the serial port between the central processing unit of the vehicle connector or the diagnosis connector and the single chip microcomputer matches with the rate that is supported by the changed bus type, so that the serial port can adapt to the rates of different buses, that is, the serial port can be adjusted to different transmission rates according to different bus types, thereby avoiding the problems of the prior art.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
