They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] Currently, when upgrading vehicle firmware or software using Over-The-Air (OTA) technology, a single channel is typically used to transmit upgrade data packets. This leads to increasing congestion on the network transmission channel, slowing down the transmission rate of upgrade data packets and even causing upgrade failures due to channel failures. Therefore, existing technologies suffer from low transmission efficiency for upgrade data packets.

[0048] To address this, this application proposes an upgrade data packet transmission apparatus, method, and vehicle. The apparatus includes a sending module, a forwarding module, and a receiving module. The forwarding module includes a first gateway and at least one second gateway, which are connected in series to form a transmission loop. A first end and a second end of the sending module are electrically connected to the transmission loop, respectively. The receiving module is electrically connected to the first gateway. Thus, the first end, the first gateway, and the receiving module are connected in series to form a first channel, and the second end, each of the second gateways, the first gateway, and the receiving module are connected in series to form a second channel. By providing one first channel and at least one second channel, during OTA upgrades of the vehicle, it can be ensured that even if one channel fails, upgrade data packets can still be transmitted through other channels, improving the transmission efficiency of upgrade data packets and thus ensuring the success rate of OTA flashing upgrades.

[0049] In one embodiment, such as Figure 1 As shown, an apparatus for transmitting upgrade data packets is provided, comprising:

[0050] The delivery module includes a first terminal 1 and a second terminal 2, which are used to generate a first message and at least one second message based on the upgrade data packet, and to deliver the first message and each of the second messages.

[0051] In one specific implementation, the distribution module further includes an upgrade master control unit for generating the first message and each of the second messages, and the first end 1 and the second end 2 of the distribution module are electrically connected to the transmission loop via Ethernet respectively.

[0052] Specifically, the steps of upgrading the main control unit to generate the first message and various second messages include: obtaining a destination address, a preset first flag, a first protocol address and a logical address of the first terminal 1, wherein the destination address is used to indicate the address of the receiving module receiving the upgrade data packet; configuring the first message according to the first flag, the first protocol address, the logical address, the destination address and the upgrade data packet; obtaining a preset second protocol address, a logical address and at least one second flag of the second terminal 2, wherein the number of second flags matches the number of second channels, and the destination address is used to indicate the address of the receiving module receiving the upgrade data packet; configuring the corresponding second message according to each of the second flags, the second protocol address, the logical address, the destination address and the upgrade data packet.

[0053] It should be noted that the first and second flags are used by the receiving module to determine whether the corresponding upgrade data packet was transmitted through the first channel or the second channel after parsing the received first and second messages. For example, assuming the first flag is "0x01" and the second flag is "0x02", the receiving module, after receiving the first and second messages, can determine through parsing that the upgrade data packet in the first message was transmitted through the first channel based on "0x01", and that the upgrade data packet in the second message was transmitted through the second channel based on "0x02".

[0054] In one implementable manner, the first and second messages may further include an upgrade packet flag, wherein, in the first message, such as Figure 2 As shown, the upgrade packet flag, first flag, first protocol address, logical address, destination address, and upgrade packet are ordered from front to back and sent and received in chronological order; in the second message, as... Figure 3 As shown, the upgrade packet flag, second flag, second protocol address, logical address, destination address, and upgrade packet are arranged in a forward-to-back order and sent and received in chronological order. The destination address can be either a logical address or a protocol address; the first protocol address, second protocol address, logical address, and destination address are unique across the entire network; the upgrade packet flag indicates that the first or second message carries an upgrade packet. For example, the upgrade packet flag can be "0Xaaaa5555".

[0055] It should be noted that, Figure 2 and Figure 3This is only used to illustrate the data structure of the first and second messages, and is not used to illustrate the length of each bit within the message. For example, the upgrade data packet, the first flag, the second flag, the logical address, and the destination address can be 2 bytes long, the first protocol address and the second protocol address can be 4 bytes long, and the upgrade data packet can be the longest, for example, 1436 bytes long.

[0056] The forwarding module includes a first gateway and at least one second gateway, wherein the number of second messages and the number of second gateways are matched, the first gateway and at least one second gateway are connected in series to form a transmission loop, and the first terminal 1 and the second terminal 2 of the sending module are electrically connected to the transmission loop respectively.

[0057] Specifically, the first gateway and each of the second gateways include an upgrade agent unit for forwarding the first message and each of the second messages, and the first gateway and at least one of the second gateways form a loop through Ethernet.

[0058] The receiving module is electrically connected to the first gateway and is used to receive the first message through the first channel and to receive the corresponding second message through each of the second channels. The first terminal 1, the first gateway and the receiving module are connected in series to form the first channel, and the second terminal 2, each of the second gateways, the first gateway and the receiving module are connected in series to form each of the second channels.

[0059] Specifically, in combination Figure 1 and Figure 4 The receiving module includes a first control submodule and at least one second control submodule, wherein the number of second control submodules and second gateways are matched, and at least one second control submodule is electrically connected to each of the second gateways; the first terminal 1, the first gateway, and the first control submodule are connected in series to form the first channel, and the second terminal 2, each of the second gateways, the first gateway, and the first control submodule are electrically connected to form a corresponding second channel. It should be noted that the number of second gateways in the second channel is at least one, such as... Figure 5 The dotted line portion shown indicates that the second channel can be formed by sequentially connecting a second terminal 2, a second gateway, a first gateway, and a first control submodule; as shown... Figure 6 The dotted line portion shown indicates that the second channel can also be formed by sequentially connecting the second terminal 2, two adjacent second gateways, the first gateway, and the first control submodule; for example... Figure 7 The dotted line portion shown indicates that the second channel can also be formed by connecting the first terminal 1, three second gateways, the first gateway, and the first control submodule in series.

[0060] Furthermore, such as Figure 8As shown, the first control submodule and each of the second control submodules each include at least one control unit. Each control unit includes an upgrade slave control unit for receiving the first message and each of the second messages. Each control unit of the first control submodule is electrically connected to the first gateway via Ethernet or a controller area network (CAN), and each control unit of the second control submodule is electrically connected to the second gateway via Ethernet or a CAN. The control unit may be an Electronic Control Unit (ECU), and at least one control unit is connected in series in either the first or second control submodule.

[0061] It should be noted that the upgrade slave control unit of the receiving module will determine whether a redundant channel is configured. If no redundant channel is configured, that is, only one channel is configured, then a third message is configured according to the upgrade data packet flag, the preset third flag, the protocol address, logical address, destination address of the sending module, and the upgrade data packet. The third message is transmitted from the channel so that the upgrade slave control unit receives the third message carrying the upgrade data packet. The third flag is used to indicate that only one channel is configured. For example, taking the aforementioned first flag and second flag as examples, the third flag can be a string other than the first flag and the second flag. If redundant channels are configured, i.e., at least one second channel as mentioned above, and the network status of the first channel and each second channel is normal, the upgrade slave control unit will receive the first message and each second message. It will parse the first message to obtain the first flag and each second message's second flag. Based on the first flag, it will determine that the upgrade data packet in the first message was transmitted through the first channel; based on the second flag of each second message, it will determine that the upgrade data packet in each second message was transmitted through the corresponding second channel. In this case, only one upgrade data packet needs to be saved; for example, the upgrade data packet transmitted through the first channel is saved, and the upgrade data packets transmitted through each second channel are discarded. If there is a faulty channel among the first channel and each second channel, the upgrade slave control unit will receive at least one first message and / or second message transmitted through a non-faulty channel. It will parse the corresponding upgrade data packet and save one of the upgrade data packets.

[0062] In summary, by providing redundant channels, the device enables vehicles to transmit data via a first channel and at least one second channel when upgrading via OTA. This ensures that even if one channel fails, upgrade data packets can still be transmitted through other channels, improving the transmission efficiency of upgrade data packets and thus guaranteeing the success rate of OTA flashing and upgrading.

[0063] In another embodiment, a method for transmitting upgrade data packets is provided, the method being applied to the upgrade data packet transmission apparatus described in the foregoing embodiments, comprising:

[0064] A first message and at least one second message are generated based on the upgrade data packet. The first message is transmitted through the first channel, and each second message is transmitted through at least one second channel, wherein the number of second messages and the number of second channels match.

[0065] If the network status of the first channel and each of the second channels is normal, receive and parse the first message and each of the second messages to obtain the upgrade data packets transmitted through the first channel and each of the second channels, save the upgrade data packets transmitted through the first channel and discard the upgrade data packets transmitted through each of the second channels;

[0066] If a faulty channel exists in the first channel and at least one of the second channels, at least one first message and / or second message from a non-faulty channel are received and parsed to obtain and save one of the upgrade data packets.

[0067] As a specific implementation, the step of generating a first message based on an upgrade data packet includes: obtaining a destination address, a preset first flag, a first protocol address of the first end, and a logical address, wherein the destination address is used to indicate the address of the receiving module that receives the upgrade data packet; and configuring the first message according to the first flag, the first protocol address, the logical address, the destination address, and the upgrade data packet.

[0068] As a specific implementation, the first message further includes an upgrade data packet flag, wherein the upgrade data packet flag, the first flag, the first protocol address, the logical address, the destination address, and the upgrade data packet are arranged in a forward-to-back order and sent and received in a sequential order.

[0070] In one specific implementation, each of the second messages further includes an upgrade data packet flag, wherein the upgrade data packet flag, the second flag, the second protocol address, the logical address, the destination address, and the upgrade data packet are arranged in a forward-to-back order and sent and received in a sequential order.

[0071] As a specific implementation, the step of receiving and parsing the first message and each of the second messages includes: receiving and parsing the first message and each of the second messages to obtain a first flag of the first message and a second flag of each of the second messages; determining, based on the first flag, that the upgrade data packet in the first message is transmitted through the first channel; and determining, based on the second flag of each of the second messages, that the upgrade data packet in each of the second messages is transmitted through the corresponding second channel.

[0072] Specific limitations regarding the transmission method of upgrade data packets can be found in the limitations on the transmission device for upgrade data packets described above, and will not be repeated here. Each module in the aforementioned transmission device for upgrade data packets can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in hardware or independently of the processor in the computer device, or stored in software in the memory of the computer device, so that the processor can call and execute the operations corresponding to each module.

The transmission device can execute the steps of the upgrade data packet transmission method described in the foregoing embodiments when the vehicle is upgraded via OTA, thereby ensuring that the upgrade data packet can still be transmitted through other channels when one channel fails, improving the transmission efficiency of the upgrade data packet, and thus ensuring the success rate of OTA flashing and upgrading.
