[0037] Please refer to Figure 1 , which shows a schematic flowchart of a data transmission method provided by an embodiment of the present application. This data transmission method can be applied to the electronic control unit of a vehicle and specifically may include:

[0038] Step 101, obtain vehicle information to be processed, where the vehicle information includes identification information.

[0039] Step 102, based on the identification information, determine whether the vehicle information is text information.

[0040] Step 103: In response to the vehicle information being text information, use a preset text encoding rule to perform conversion processing on the text information to obtain a text signal message corresponding to the text information. The text signal message includes at least one text unit, and each text unit occupies a preset byte length.

[0041] Step 104: Transmit the text signal message to the bus, so as to transmit the text signal message to the data collector through the bus.

[0042] It should be noted that the vehicle information may include identification information, application program information, vehicle driving information, status values of various vehicle components, etc.

[0043] It should be noted that the text information may include information obtained based on the application program of the in-vehicle central control. For example, navigation destination address information, vehicle positioning address information, etc.

[0044] It should be noted that here, the bus may include a CAN bus, a CANFD bus, etc.

[0045] In this way, by using a preset text encoding rule to perform conversion processing on the text information, a text signal message that can be used for bus transmission can be obtained, and the text information can be transmitted to the data collector of the vehicle through the bus, realizing the collection and storage of the text information. It can directly transmit text information of Chinese characters, letters, and numbers through the CAN bus to the data collector of the vehicle for the backup of the whole vehicle information and the application of other components, which can optimize the richness of the data transmission of the CAN bus.

[0046] Optionally, in a possible implementation manner of this embodiment, in step 103, first, based on the text information, the preset byte length, and the fixed byte length of the text signal message, obtain the sequence numbers and signal attributes of multiple text signal messages corresponding to the text information. Secondly, for each text signal message, based on the sequence number and signal attribute of the text signal message, determine the encoding information corresponding to the fixed byte of each text signal message, and perform conversion processing on the text in the text information according to the preset byte length to obtain at least one text unit of each text signal message. Thirdly, based on the encoding information corresponding to the fixed byte of each text signal message and at least one text unit of each text signal message, obtain the text signal message corresponding to the text information.

[0047] In a specific implementation process of this implementation manner, the characters in the text information can be converted according to a preset byte length to obtain a plurality of character units. Furthermore, in response to determining that the byte length corresponding to the characters in the text information is less than the preset byte length, byte padding can be performed on the characters in the text information with a byte length less than the preset byte length, so that the byte length of the characters in the filled text information is equal to the preset byte length.

[0048] In one case of this specific implementation process, preset characters can be used to perform byte padding on the characters in the text information with a byte length less than the preset byte length.

[0049] Here, the preset character can be FF or the like.

[0050] In this implementation manner, a text signal message can include 8 bytes, the preset byte length can be 3 byte lengths, and the length of the fixed bytes of the text signal message can be 2 byte lengths. A text signal message can include 2 bytes of the preset byte length and 1 byte of the fixed byte length. The 2 bytes of the preset byte length are 2 character units.

[0051] In this implementation manner, the sequence number of the text signal message can be the sequence number of the text signal message in the plurality of text signal messages corresponding to the text information.

[0052] In this implementation manner, the signal attributes of the text signal message can include a character category value and the number of messages. For example, a character category value of 0 can indicate that the character represents a country, and a character category value of 1 can indicate that the character represents a province or city.

[0053] In a specific implementation process of this implementation manner, based on the text information, the preset byte length, and the length of the fixed bytes of the text signal message, the number of text signal messages corresponding to the text information, that is, the number of message strips corresponding to the text information, the sequence number of each text signal message, and the character category value corresponding to each character in the text information can be obtained.

[0054] Optionally, in a possible implementation manner of this embodiment, the characters in the text information include at least one of Chinese characters, letters, and numbers.

[0055] In a specific implementation process of this implementation manner, one Chinese character can correspond to a preset byte length, that is, 3 bytes. One Chinese character can be used as one character unit. Letters and padding characters can correspond to a preset byte length. Numbers and padding characters can correspond to a preset byte length.

[0056] Here, a text signal message can include 8 bytes. When the preset byte length is 3 bytes, a text signal message can include 2 text units.

[0057] Exemplarily, if the vehicle information to be transmitted is navigation address information, 1 Chinese character in the navigation address information corresponds to 1 text unit, 1 letter corresponds to 1 text unit, and 1 digit corresponds to 1 text unit. Thus, it is possible to directly transmit the navigation address information to the data collector through the CAN bus.

[0058] It can be understood that a text signal message can include 2 Chinese characters, 2 letters, 2 digits, 1 Chinese character and 1 letter, 1 Chinese character and digit, 1 letter and 1 digit.

[0059] Optionally, in a possible implementation manner of this embodiment, the preset text encoding rule includes one of the UTF-8 encoding rule and the custom encoding rule.

[0060] In this implementation manner, the custom encoding rule is the rule of custom text encoding. [[ID=I3]]

[0061] Optionally, in a possible implementation manner of this embodiment, after step 104, the data collector can locally store the text information corresponding to the text signal message and upload the text information corresponding to the text signal message to the cloud.

[0062] Optionally, in a possible implementation manner of this embodiment, after step 102, in response to the vehicle information not being text information, use the preset data transmission protocol to transmit the vehicle information to the bus, so as to transmit the text signal message to the data collector through the bus.

[0063] In this implementation manner, here, when the vehicle information is not text information, the vehicle information can be physical value information.

[0064] In a specific implementation process of this implementation manner, use the preset data transmission protocol to convert the vehicle information into a physical value message, and then the physical value message can be transmitted to the bus.

[0065] It should be noted that the specific implementation process provided in this implementation manner can be combined with the multiple specific implementation processes provided in the foregoing implementation manner to implement the data transmission method of this embodiment. For detailed description, reference can be made to the relevant content in the foregoing implementation manner, which will not be elaborated here.

[0066] Figure 2 Shows the structural block diagram of a data transmission device provided by an embodiment of the present application, as Figure 2As shown in the figure. The data transmission device 200 in this embodiment can be applied to the electronic control unit of a vehicle and may include an acquisition unit 201, a determination unit 202, an obtaining unit 203, and a transmission unit 204. Among them, the acquisition unit 201 is used to acquire vehicle information to be processed; the vehicle information includes identification information; the determination unit 202 is used to determine whether the vehicle information is text information based on the identification information; the obtaining unit 203 is used to, in response to the vehicle information being text information, perform conversion processing on the text information by using a preset text encoding rule to obtain a text signal message corresponding to the text information, where the text signal message includes at least one character unit, and each character unit occupies a preset byte length; the transmission unit 204 is used to transmit the text signal message to a bus, so as to transmit the text signal message to a data collector through the bus.

[0067] Optionally, in a possible implementation manner of this embodiment, the obtaining unit 203 is used to obtain the sequence numbers and signal attributes of multiple text signal messages corresponding to the text information based on the text information, the preset byte length, and the length of the fixed bytes of the text signal message; for each text signal message, determine the encoding information corresponding to the fixed bytes of each text signal message based on the sequence number and signal attribute of the text signal message, perform conversion processing on the characters in the text information according to the preset byte length to obtain at least one character unit of each text signal message; and obtain the text signal message corresponding to the text information based on the encoding information corresponding to the fixed bytes of each text signal message and at least one character unit of each text signal message.

[0068] Optionally, in a possible implementation manner of this embodiment, the obtaining unit 203 is used to perform conversion processing on the characters in the text information according to a preset byte length to obtain multiple character units; in response to determining that the byte length corresponding to the characters in the text information is less than the preset byte length, perform byte filling on the characters in the text information with a byte length less than the preset byte length, so that the byte length of the characters in the filled text information is equal to the preset byte length.

[0069] Optionally, in a possible implementation manner of this embodiment, the characters in the text information include at least one of Chinese characters, letters, and numbers.

[0070] Optionally, in a possible implementation manner of this embodiment, the preset text encoding rule includes one of the UTF-8 encoding rule and a custom encoding rule.

[0071] In this embodiment, an acquisition unit 201 can be used to acquire vehicle information to be processed; the vehicle information includes identification information; a determination unit 202 is used to determine whether the vehicle information is text information based on the identification information; an obtaining unit 203 is used to, in response to the vehicle information being text information, perform conversion processing on the text information by using a preset text encoding rule to obtain a text signal message corresponding to the text information, where the text signal message includes at least one text unit, and each text unit occupies a preset byte length, and a transmission unit transmits the text signal message to a bus, so as to transmit the text signal message to a data collector through the bus. Since the text information can be converted and processed by using the preset text encoding rule to obtain a text signal message that can be used for bus transmission, and the text information is transmitted to the data collector of the vehicle through the bus, the collection and storage of the text information can be realized, and the text information of Chinese characters, letters and numbers can be directly transmitted through the CAN bus to the data collector of the vehicle for the backup of the whole vehicle information and the application of other components, which can optimize the richness of the data transmission of the CAN bus.

[0072] In this embodiment, Figure 3 is a schematic architecture diagram of an application scenario of a data transmission method / device provided in another embodiment of the present application, as Figure 3 shown. This application scenario may include a CAN bus, an ECU, a data collector, and a cloud background.

[0073] In this embodiment, CAN1 and CAN2 are CAN buses, serving as networks for transmitting signal messages. The ECU is a controller in the vehicle and can be used to send CAN signal messages. The data collector can be used to receive the signal messages of each CAN bus and realize local storage and upload to the cloud background.

[0074] In this embodiment, first, the ECUs 1, 2, 3, 4, 5, and 6 in each network segment of the whole vehicle can obtain information such as Chinese characters, letters, and Arabic numerals in real time. When the ECU needs to transmit text information such as Chinese characters, letters, and Arabic numerals, the Chinese characters, letters, and Arabic numerals can be converted into signals of 3 bytes according to the UTF-8 protocol. Second, 8 bytes of valid data can be transmitted in each message. 3 bytes represent 1 Chinese character, letter, or Arabic numeral, that is, two valid characters can be sent in one message. The remaining two bytes in the message are used for fixed format definition. Such as the corresponding number values of each text signal information, and the number values can be used to distinguish the currently sent signal, the number of messages required to be sent corresponding to the current text signal information, heartbeat signals, etc. According to the above definition method, different text signal information can be integrated and defined as a message with a fixed format. Third, in the way of continuous frames, the bus messages converted from Chinese characters, letters, and Arabic numerals can be transmitted to the bus. After the current text signal information is sent, a specific data format message is sent as a sign that the information sending is completed. In this way, the integrity of the transmitted data can be guaranteed. Third, each network segment of the whole vehicle is connected to the data collector through the CAN bus, that is, the data collector can collect the data of each network segment. The data collector can locally store and upload to the cloud the information sent by each network segment of the whole vehicle.

[0075] Adopting the solution in this embodiment can solve the problem of transmitting Chinese characters, letters, and Arabic numerals on the CAN bus, and can locally store and upload the information for vehicle information backup and other applications.
