[0023] Figure 1The present invention provides a flowchart of a bus communication method. The present invention is applicable to the situation where the components in a two-wheeled electric vehicle perform bus communication. In this embodiment, there is no limitation on the communication standard of the bus. For example, the communication standard of the bus may be RS485. The method may be executed by a bus communication device, which may be implemented in the form of software and / or hardware. Optionally, the method may be implemented by an electronic device, which may be a mobile terminal, a PC, or a server. Figure 1 As shown, the method includes:

[0024] S110 , assigning node ID parameters to each component mounted on the bus according to the number of bus nodes.

[0025] Among them, at least one integrated component and a plurality of split components are mounted on the bus; the integrated component includes a master node and at least one slave node; the split component includes at least one slave node.

[0026] In this embodiment, there is no restriction on the components and the number of components included in the integrated component. For example, the number of components in the integrated component is 2, and the integrated component can be a body control module (Body Control Module, BCM). The integrated component can be integrated by an Application Lifecycle Management (Application Lifecycle Management, ALM) component and an Internet of Things (Internet of Things, IOT) component. The integrated component can also be integrated by an ignition control module (Ignition Control Module, ICM) component and an ALM component. Among them, the ALM component is the master node in the integrated component, and the remaining nodes are slave nodes. The nodes in the split component are all used as slave nodes.

[0027] In this embodiment, there is no restriction on the split components. For example, if the integrated component is integrated by ALM and IOT, the multiple split components can be ICM components, Motor Control Unit (MCU) components, and Battery Management System (BMS) components. For another example, if the integrated component is integrated by ALM and ICM, the multiple split components can be IOT components, MCU components, and BMS components. Among them, the MCU can also be connected to other split components, such as the Anti-lock Braking System (ABS), through the K solid line 1. The BMS can be connected to other split components, such as the Charger (CHG), through the K solid line 2.

[0028] The number of integrated component nodes is equal to the total number of all components in the integrated component, for example, the integrated component (ALM and IOT), one component, two nodes.

[0029] For example, taking ALM, IOT and ICM as examples, ALM, IOT and ICM are originally three components and three nodes. In the integrated components (ALM and IOT) and the split component ICM in this embodiment, there are two components and three nodes. Although the components are different, there are still three nodes during bus communication (that is, the nodes remain unchanged), and the bus protocol can share a copy, thereby improving the compatibility of bus communication and the reusability of bus protocol. That is, in this embodiment, node identification (ID) parameters are allocated to each component based on the number of bus nodes, and node ID parameters are not allocated based on the number of electrical components. In this way, the bus communication protocol can be uniformly designed according to the number of nodes, so that it can be consistent under different electrical architectures (that is, the number of nodes remains unchanged under different electrical architectures), thereby improving the compatibility of bus communication and the reusability of the protocol.

[0030] S120. The master node in the integrated component sends a corresponding request message to the slave nodes in the integrated component and the slave nodes in the plurality of split components through the bus.

[0031] Among them, the split component itself can be used as a slave node. It should be noted that if the MCU is not mounted with ABS, the number of slave nodes of the split component MCU is one, that is, the MCU itself is used as a slave node. If the MCU is mounted with ABS, the ABS is also used as a slave node on the basis that the MCU itself is used as a slave node. Since the ABS is connected to the MCU through a solid line, the response message of the ABS can be sent by the MCU, so that the split component MCU is equivalent to including 2 slave nodes. It should be noted that if CHG is not online, that is, the BMS is not plugged in with CHG, the number of slave nodes of the split component BMS is one, that is, the BMS itself is used as a slave node. If CHG is online, that is, the BMS is plugged in with CHG, the CHG is also used as a slave node on the basis that the BMS itself is used as a slave node. Since CHG is connected to the BMS through a solid line, the response message of CHG can be sent by the BMS, so that the split component BMS is equivalent to including 2 slave nodes.

[0032] In this embodiment, the master node in the integrated component can send corresponding request messages to the slave nodes in the integrated component and the slave nodes in multiple split components through the bus in a preset order and in combination with the received response messages.

[0033] Optionally, the master node in the integrated component sends corresponding request messages to the slave nodes in the integrated component and the slave nodes in multiple split components through the bus, including: the master node sends corresponding request messages to the slave nodes in the integrated component and the slave nodes in multiple split components in turn through the bus in a polling manner.

[0034] In this embodiment, the master node sends corresponding request messages to each slave node in a polling manner through the bus, that is, sends corresponding request messages to each slave node in sequence according to a set order. In addition, the master node can send a request message to the current slave node after receiving the request message from the previous slave node.

[0035] Optionally, the master node sends corresponding request messages to the slave nodes in the integrated component and the slave nodes in the multiple split components in turn through the bus in a polling manner, including: if the current slave node is the first slave node, the master node sends the corresponding request message to the current slave node through the bus; wherein the request message includes the ID parameter of the current slave node; if the current slave node is not the first slave node, the master node sends the corresponding request message to the current slave node through the bus based on the response message received from the previous slave node.

[0036] Exemplarily, the ID parameters of each node are distributed as shown in Table 1 below.

[0037] Table 1 Distribution of node ID parameters

[0038] node IOT ALM ICM MCU BMS ABS CHG ID Parameters 0Ah 0B 0Ch 0h 0eH 0F 10h

[0039] In this embodiment, a request message is sent to the current slave node based on the response message received from the previous slave node, which can ensure orderly and efficient communication between the master node and the slave node, avoid communication conflicts, and ensure the accuracy and integrity of the communication.

[0040] S130, the integrated component and each split component sends a response message to the master node through the bus based on the corresponding request message.

[0041] The number of response messages sent by the integrated component and each split component is one.

[0042] In this embodiment, although the number of nodes in bus communication does not change, on this basis, the number of messages in bus communication is based on the number of components. For example, for an integrated component, a response message can be sent to carry messages of all nodes included in the integrated component. For a split component, a response message can also be sent to carry a message of at least one node included in the split component. Therefore, not only can the bus communication protocol be reused, but the number of messages can also be reduced, which can solve the problem of too many bus communication messages, resulting in a longer bus duration and low bus efficiency, and can improve the flexibility and communication efficiency of component communication.

[0043] Optionally, the integrated component and each split component send response messages to the master node through the bus based on the corresponding request message, including: if the current slave node is a slave node in the integrated component, then the response message sent by the current slave node to the master node carries the message information of all nodes in the integrated component; if the current slave node is one of multiple slave nodes in the split component, then the response message sent by the current slave node to the master node carries the message information of multiple slave nodes in the split component; if the current slave node is the only slave node in the split component, then the response message sent by the current slave node to the master node carries the message information of the current slave node in the split component.

[0044] Exemplarily, the number of nodes included in the integrated component and the split component is taken as two, and the response message format is as shown in Table 2 below.

[0045] Table 2 Response message format

[0046]

[0047]

[0048] Among them, the length LEN1 is the length of data content 1, and the length LEN2 is the length of data content 2. Data content 1 is the message corresponding to node ID1, and data content 2 is the message corresponding to node ID2.

[0049] In this embodiment, if two nodes of an integrated component or a split component need to be sent simultaneously, node ID1, length LEN1, and data content 1 are the message of node 1, and node ID2, length LEN2, and data content 2 are the message of node 2, as shown in Table 3, Table 4, Table 5, and Table 6.

[0054]

[0055] Table 5 MCU (when ABS is installed) response message

[0056]

[0057] In this embodiment, the MCU component is connected to the ABS through the K line. When the ABS is mounted as an optional component, the MCU sends the ABS message information on the bus. Therefore, the BMS component sends a response message. The response message sent by the MCU (when the ABS is installed) carries the message information of the MCU node and the ABS node. The response message sent by the MCU (when the ABS is not installed) carries the message information of the MCU node, thereby improving communication efficiency.

[0058] Table 6 BMS (when charger is plugged in) response message

[0059]

[0060]

[0061] In this embodiment, the charger CHG is not real-time online and is not directly mounted on the bus, but it still needs to communicate on the bus and can use the BMS node to send it. Therefore, the BMS component sends a response message. When the charger is plugged in, the response message sent carries the message information of the BMS and CHG nodes. When the charger is not plugged in, the response message sent carries the message information of the BMS, thereby improving communication efficiency.

[0062] In this embodiment, when the split component has only one node, node ID1, length LEN1, data content 1 is the message of node 1, node ID2 and length LEN2 are 0, and data content 2 is none, as shown in Table 7, Table 8, Table 9 and Table 10.

[0069]

[0070] Table 10 BMS (charger not detected) response message

[0071]

[0072] In this embodiment, when the charger is not plugged in, the response message sent carries the message information of the BMS.

[0073] In this embodiment, the response message sent by the slave node in the integrated component to the master node carries the message information of all nodes in the integrated component. When the split component includes multiple nodes, the response message sent by the split component to the master node carries the message information of multiple slave nodes in the split component, which can improve the bus communication efficiency.

[0074] Optionally, the master node reads the response message sent by each slave node in real time. Each slave node reads the request message sent by the master node to each slave node in real time.

[0075] In this embodiment, when the master node sends a request message to any slave node, all slave nodes will read the request message in real time through the bus, and each slave node will read the request message sent by the master node to each slave node in real time. After each slave node receives the request message, if the ID parameter carried in the request message is consistent with the ID parameter of its own node, the corresponding component (or slave node) sends a response message to the master node through the bus, and the master node and the slave node will receive and read the response message in real time. After the master node receives the response message, it sends a request message to another component (or slave node). If the ID parameter carried in the request message is inconsistent with the ID parameter of its own node, no operation is performed.

[0076] In this embodiment, the nodes of each component on the bus can read message information (including request messages and response messages) from the bus in real time, thereby improving communication efficiency.

[0077] For example, Figure 2 A bus communication node topology diagram is provided for an embodiment of the present invention. Figure 2 In the figure, each node has a corresponding node ID. The dotted ABS and CHG are not online in real time. ABS can be optional or installed later. CHG is offline when not charging and online when charging.

Among them, the node of the ALM component is the ALM node, which is the master node, and the node of the IOT component is the IOT node, which is the slave node. The node of the ICM component is the ICM node, which is the slave node. The node of the MCU component is the MCU node, which is the slave node. The node of the BMS component is the BMS node, which is the slave node. The ALM node sends a request message to the IOT node through the bus. The IOT node is a node in the integrated component. The response message sent by the integrated component through the bus carries the message of the IOT node and the ALM node. The ALM node sends a request message to the ICM node through the bus. The response message sent by the ICM component through the bus carries the message of the ICM node. The ALM node sends a request message to the MCU node through the bus. If the MCU component is mounted with the ABS component, the response message sent by the MCU component through the bus carries the message of the MCU node and the ABS node. If the MCU component is not equipped with an ABS component, the response message sent by the MCU component through the bus carries the message of the MCU node. The ALM node sends a request message to the BMS node through the bus. If the CHG component is plugged into the BMS component, the response message sent by the BMS component through the bus carries the messages of the BMS node and the CHG node. If the CHG component is not plugged into the BMS component, the response message sent by the BMS component through the bus carries the message of the BMS node.

The ALM node sends a request message to the ICM node through the bus, and the response message sent by the integrated component through the bus carries the messages of the ICM node and the ALM node. The ALM node sends a request message to the MCU node through the bus. If the MCU component is mounted with the ABS component, the response message sent by the MCU component through the bus carries the messages of the MCU node and the ABS node. If the MCU component is not mounted with the ABS component, the response message sent by the MCU component through the bus carries the message of the MCU node.
