Detailed Description
In the prior art, in order to implement state control of a part of networks, hardware needs to be modified in a matching manner, and all automobile Open System Architecture (Automotive Open System Architecture) network management ECUs need to replace part of network (CAN-PN, partial Networking) transceivers. The influence of the change on the platform-based vehicle type is large, and the development cost of hardware change and the switching cost of mass-produced vehicles on the same platform are expensive.
The method provided by the embodiment of the application is executed by computer equipment and used for reducing the cost of partial network dormancy.
It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a method of a state control method of a partial network according to an embodiment of the present application, including:
step S101: and the slave node receives the network management message sent by the master node.
The master node and the slave nodes are electronic control units and respectively correspond to a primary control end and a secondary control end. The main node is a main control node and is used for identifying user scenes and performing main control of partial network dormancy awakening. The slave node is a gateway electronic control unit and is used for forwarding the control instruction of the master node to the responding network segment or routing the awakening requirement of other network segments to the master node.
Step S102: and the slave node analyzes the network management message to obtain a response network segment corresponding to the network management message.
The network management packet may indicate that the slave node performs subsequent operations, including whether forwarding to the response segment is required, the content of the response segment, and the like. And the slave node analyzes the network management message to obtain a response network segment corresponding to the network management message, and then forwards the message content to the response network segment so as to facilitate a controller of the response network segment to execute corresponding operation. The slave node has a routing function, routes the network management message to the response network segment, combines the master node and the controller on the response network segment together, and forms three-level joint control to increase the work of the transceiver to the master node and the slave node, thereby being beneficial to saving cost and modifying and producing the mass production of vehicles.
Step S103: and the slave node sends the network management message to the response network segment.
After the slave node acquires the response network segment, the received network management message can be directly sent to the response network segment, so that the controller corresponding to the response network segment can conveniently execute the awakening operation. At this time, the controller corresponding to the response network segment is a three-level control end. Therefore, the master node, the slave nodes and the controller jointly form three-level joint control, and the work of the transceiver is executed by the master node and the slave nodes, so that the state control of part of the network can be realized without modifying the transceiver, and the method is favorable for saving the cost and modifying and producing the mass production of vehicles.
It should be noted that the waking at this time may be to wake up the controller in the sleep state, or to keep the controller in the wake-up state and not perform the sleep operation.
In summary, in the embodiment, the controller of the response network segment is controlled by the master node and the slave node, the master node controls the slave node, the slave node controls the controller of the response network segment, and the state control operation of part of the network is performed hierarchically by adopting a three-level joint control manner, so that the function of the transceiver is integrated into the master node and the slave node, the purpose of realizing the state control of part of the network without modifying the transceiver is achieved, the cost is low, and the platform vehicle type volume production is facilitated.
Referring to fig. 2, this figure is another method flowchart of a state control method for a partial network according to an embodiment of the present application, including:
step S201: and receiving a network management message transmission request periodically sent by the master node by the slave node.
After detecting the local trigger condition of function activation, the master node can quickly send the wake-up network management message in a periodic form and start counting. The sent wake-up network management message comprises a PNI position bit and a related function group bit. And the slave node can receive the network management message sent by the master node within the preset time after the master node sends the network management message. Specifically, the slave node needs to receive a network management message transmission request periodically sent by the master node first, and then receive a network management message transmitted by the master node.
Therefore, within a preset time after the master node sends the network management message, the slave node receives a network management message transmission request periodically sent by the master node.
Step S202: and the slave node receives the network management message sent by the master node.
The above steps are the same as those in the above embodiments, and are not described herein again.
Step S203: and the slave node analyzes the PNI bit and the related function group bit of the network management message to obtain a response network segment corresponding to the network management message.
As a possible implementation manner, the network management packet includes a PNI bit and a related function group bit, which are used to indicate whether to forward to the response segment and the content of the response segment.
It should be noted that the slave node does not set the PNI position and the related function group sets the PNI position in response to the network management packet, and does not send the network management packet to the response network segment. If PNI =0, this means that there is no PN request in the network management message, and there is no further processing of the PN function. If PNI =1, meaning that there is a PN request in the network management message, further processing of the PN function is required, i.e., analyzing the relevant function group set.
The related function group may represent operations that need to be performed subsequently, and whether the network management packet is related to the current slave node or not may be obtained through analysis, and when the network management packet is related to the current slave node, to which network segment the current slave node needs to forward, that is, the response network segment.
It should be noted that, when the PNI bit in the network management packet is not related to the current slave node and the relevant function group bit is not related to the current slave node, the obtained response network segment corresponding to the network management packet is empty, that is, the slave node does not need to perform subsequent operations.
As a possible implementation, the correspondence between partial function groups and response segments is shown in the following table:
wherein, the left side header represents the function group, the top header represents the network segment, and the position selected by x is the response network segment corresponding to the left side function group.
Except the above table, when the main node is CCU-CAN and the function group PNC is set, only subCAN is in the response network segment; and when the main node is the other CAN, the response network segment is all the CAN.
Step S204: and the slave node sends the network management message to the response network segment.
The above steps are the same as those in the above embodiments, and are not described herein again.
Step S205: and responding to the network dormancy timer reaching a first preset threshold value, and executing the dormancy operation by the slave node.
When the slave node starts to receive the network management message sent by the master node, the network management timer is reset until the network management message is received, and the network management timer reaches a second preset threshold value. At this time, the network dormancy timer is triggered until the network dormancy timer reaches a first preset threshold value, and the slave node executes dormancy operation. The first preset threshold and the second preset threshold may be set according to the computing power of the master node or the slave node, and are not limited herein.
For ease of understanding, the present embodiment will be explained below by exemplifying a T-box remote control and a scheduled charging scheme. The main node ECU is a T-box, and when a T-box remote control function (comprising remote unlocking, remote control skylight, remote vehicle searching, remote back door control, remote back defrosting control and the like) is activated, a network management message of a PNI position bit and a function group Comfort _ Awake position bit is sent to an SC _ CAN network. The slave nodes on the SC _ CAN network CAN receive the network management messages, and then the CCU (routing function) in the slave nodes recognizes the network management messages with the PNI bit and the function group bit, and sends the network management messages with the same bit to the response network segments VIU _ L _ CAN, VIU _ F _ CAN, and VIU _ R _ CAN, so that the controllers of the above network segments execute corresponding operations. The network management system comprises a node analysis network management message, a network management server and a network management server, wherein the node analysis network management message comprises a node and a network management server, the network management server comprises a network management server, a network management server and a controller, and the network management server comprises a VIU _ L _ CAN, a VIU _ F _ CAN and a VIU _ R _ CAN.
In summary, the slave node in this embodiment obtains a subsequent forwarding indication by analyzing a specific setting of the network management packet, and explains the three-level joint control result in detail, so that the purpose of realizing state control of part of networks without modifying the transceiver is achieved, the cost is low, and the platform vehicle model volume production is facilitated; meanwhile, the slave node can automatically sleep, which is beneficial to reducing excessive energy consumption.
Referring to fig. 3, this figure is a flowchart of another method of a method for controlling a state of a partial network according to an embodiment of the present application, where the method includes:
step S301: the master node sends a network management message to the slave nodes.
The master node and the slave nodes are electronic control units, and the network management message is used for indicating part of network awakening. After detecting the local trigger condition of function activation, the main node can send the wake-up network management message in a periodic form at a high speed and start counting. The sent wake-up network management message comprises a PNI position bit and a related function group bit, and is used for indicating whether the slave node needs to be forwarded to the response network segment and the content of the response network segment. It should be noted that the network management packet sent by the master node needs to be received within a preset time, otherwise, the control fails.
Step S302: and responding to the satisfaction of the sleep condition in the main node, and stopping sending the network management message by the main node.
And when the sleep condition inside the main node is met, namely the main node is no longer in an activated state, the main node stops sending the network management message.
As a possible implementation manner, when the slave node starts to receive the network management message sent by the master node, the network management timer is reset until the network management message is received, and the network management timer reaches the second preset threshold. At this time, the network dormancy timer is triggered until the network dormancy timer reaches a first preset threshold, and the master node executes the dormancy operation. The first preset threshold and the second preset threshold may be set according to the computing capability of the master node or the slave node, and are not limited herein.
In summary, in the embodiment, by explaining the stop operation and the sleep mode of the master node, the master node automatically stops sending and sleeps the network management packet through the built-in timing device, so that the power consumption of the master node is sufficiently reduced, and the purpose of saving energy is achieved.
