Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
In order to solve the above problems, the first aspect of the present invention provides a method for implementing a heavy truck gateway, by which a gateway function of a whole truck can be implemented by using a combination meter without developing a new gateway, thereby saving component cost.
The following describes an implementation method of a heavy truck gateway according to an embodiment of the present invention with reference to fig. 1, wherein a heavy truck is provided with a combination meter, and the implementation method is used for the combination meter, and as shown in fig. 1, the implementation method at least includes steps S1-S3.
Step S1, the original message sent by the sending node on the source network is received.
In the embodiment, the existing combination instrument of the heavy truck is taken as a display and an alarm of each system in the whole truck, and information interaction exists between the combination instrument and each system of the whole truck, so that on the basis of the functions of the combination instrument, the gateway function is assumed by the combination instrument to meet the communication requirements of each system of the whole truck for the gateway, so that gateway parts do not need to be developed again, the cost of the parts is saved, meanwhile, on the basis of the information communication functions of the combination instrument and each system of the whole truck, compared with a way of adding new gateway parts from the aspect of whole truck development, the gateway function is only expanded on the basis of the existing functions of the combination instrument, the development workload is small, and the development difficulty is reduced. The gateway function is to forward messages or signals between different subnets to meet the communication requirements of each system controller for the messages or signals, so as to realize cooperative coordination between systems and normal functions of the systems.
The source network may be understood as a source network of the original message. Specifically, based on information interaction between the combination instrument and each system of the whole vehicle, the combination instrument CAN receive original messages sent by each network in the whole vehicle through the CAN bus.
Step S2, obtain the target network information contained in the original message to determine the target network.
The target network information may include an IP address and a subnet mask of the target network. Therefore, the target network is determined by the target network information contained in the original message, so that the original message can be sent to the target network subsequently.
And step S3, sending the original message to a receiving node on the target network according to the target route type.
In the embodiment, the target routing types are different, and the sending forms of the original message are also different, so that after the target network is determined, the original message is sent to the target network in the corresponding sending form according to the target routing types, and therefore the gateway communication requirements of all systems of the whole vehicle are met.
According to the implementation method of the heavy truck, the combination instrument is used for receiving the original message sent by the sending node on the source network, the target network information contained in the original message is obtained to determine the target network, and therefore the original message is sent to the receiving node on the target network according to the target routing type, the gateway function requirements of the whole truck are met by the combination instrument, a new gateway does not need to be developed, and the part cost is saved.
In some embodiments, if the type of the target routing is a packet routing, the original packet is directly sent to the receiving node on the target network within the first routing time, that is, for the packet routing, when the combination meter executes the gateway function, the combination meter does not change any attribute of the original packet received from the source network, but directly sends the original packet to the receiving node of the target network, so as to implement the packet routing function of the combination meter.
The routing time may be understood as the time from when the combination meter receives the original message of the source network to when the message is transmitted to the target network. Based on this, for the message routing, when the combination meter receives all routing messages, i.e. the original messages, the combination meter needs to be sent to the target network from the source network within the first routing time, e.g. 2 ms.
In some embodiments, before an original message is directly sent to a receiving node on a target network within a first routing time, a method for implementing the embodiment of the present invention includes detecting a vehicle state and detecting a message transceiving state of a source network and a target network, where the vehicle state includes a power-on state and a power-off state, and the message transceiving state includes a dormant state and an active state; and sending the original message according to the vehicle state and the message receiving and sending state.
In some embodiments, it is determined that the vehicle is in a power-on state, if the source network is in an active state, it is indicated that the controllers on the source network all normally receive and transmit the CAN message, that is, the original message exists, and the combination instrument sends the original message to the target network; if the source network is in a dormant state, the controller on the source network stops sending and receiving the CAN message, namely the original message does not exist or is lost, and the combination instrument does not send the original message to the target network.
In some embodiments, it is determined that the vehicle is in a power-off state, if the source network is in a dormant state and the target network is in an active state, it indicates that the controllers on the source network all stop sending and receiving the CAN messages, that is, the original messages do not exist, and the controllers on the target network all normally send and receive the CAN messages, the combination meter replaces the original messages with invalid values, and sends the invalid values to the target network; or, if the target network is in a dormant state, the combination meter does not send the original message to the target network no matter the source network is in an active state or a dormant state.
In some embodiments, if the type of the target route is signal route, extracting target signals from different received messages of the source network, repackaging the target signals to form a new message meeting the requirement of a receiving node of the target network, and further sending the new message to the receiving node on the target network within the second routing time. Specifically, because the source networks are different and the received original messages are different, required signals in different received messages of the source networks need to be extracted to be used as target signals, and then the target signals are repackaged to form new messages meeting the requirements of receiving nodes of the target networks, and the new messages are sent to the target networks in the form of gateway autonomous messages, so that the signal routing function of the combination meter is realized.
Wherein for signal routing, the second routing time is dependent on the longest period of the routing signal.
In some embodiments, before sending the new packet to the receiving node on the target network within the second routing time, the implementation method of the embodiments of the present invention further includes detecting packet transceiving states of the source network and the target network, where the packet transceiving states include a dormant state and an active state; if the target network is in a dormant state, the controller on the target network stops sending and receiving the CAN message, and the combination instrument does not send a new message to the target network; if the target network is in an active state and the source network is in an active state, the controller on the source network normally receives and transmits the CAN message, namely the original message exists, and the controller on the target network normally receives and transmits the CAN message; if the target network is in an active state and the source network is in a dormant state, the controller on the source network stops receiving and sending the CAN message, namely the original message does not exist or is lost, the controller on the target network normally receives and sends the CAN message, the combined instrument replaces the new message with an invalid value and sends the invalid value to the target network, and therefore the signal routing function of the combined instrument is achieved.
In some embodiments, the implementation method of the embodiments of the present invention further includes monitoring the message transceiving state of each transceiving node on each communication network of the vehicle, and prompting if there is a message loss, that is, the combination meter has a network monitoring function, and monitors whether there is a message loss, that is, an overtime condition, at each transceiving node on the communication network, and if there is a message loss at a certain transceiving node, records a missing fault code of the transceiving node, so as to meet the node monitoring requirement of each communication network of the entire vehicle through the combination meter.
In short, according to the implementation method of the heavy truck gateway provided by the embodiment of the invention, the existing combination instrument of the heavy truck is adopted, so that the routing function of messages and signals between different networks of the whole truck can be realized by depending on the expanded gateway function of the combination instrument on the basis of not increasing an independent gateway controller, and the cost of parts is saved without newly developing gateway parts.
In a second embodiment of the present invention, a combination meter is provided, as shown in fig. 2, where the combination meter 10 includes at least one processor 1 and a memory 2 communicatively connected to the at least one processor 1.
The memory 2 stores a computer program executable by the at least one processor 1, and the at least one processor 1 implements the implementation method of the heavy truck gateway provided in the above embodiment when executing the computer program.

According to the combination meter 10 of the embodiment of the invention, the processor 1 executes the implementation method of the heavy truck gateway provided by the embodiment, so that the gateway function of the whole truck can be realized by using the combination meter without developing a new gateway, and the part cost is saved.
In some embodiments, as shown in fig. 2, the combination meter 10 further includes a prompting unit 3, and the prompting unit 3 is connected to at least one processor 1 and is used for prompting when there is a message loss.
In the embodiment, the prompting unit 3 includes a display screen, displays the state of the whole vehicle and vehicle information through the display screen, and displays or prompts the alarm content of part of the interface, i.e. the message content forwarded by the combination meter or monitors the information content of other controller nodes, such as the overtime content of the system in the whole vehicle, so that the combination meter is used to assume the gateway function of the whole vehicle, and in combination with the information content displayed by the combination meter 10, when the gateway function related to the display content has problems, such as the failure of the message routing or signal routing and network monitoring function, no other diagnosis equipment is needed, the failure source can be intuitively locked through the combination meter 10, thereby providing a channel of a human-computer interaction interface corresponding to the gateway function while the combination meter 10 realizes the gateway function of the whole vehicle, and realizing the intuitive monitoring of the related communication conditions, the user can conveniently and visually know the condition of the whole vehicle, and the intellectualization is improved.
For example, taking the routing and forwarding of the total mileage packet by the combination meter 10 as an example, the total mileage is originally displayed on the display screen of the combination meter 10, and if the function of the controller of the target network that needs to count the mileage packet is abnormal due to the abnormal total mileage packet, since the display value of the total mileage of the combination meter 10 is consistent with the total mileage value forwarded by the combination meter 10, it is able to visually confirm whether the packet routing function of the combination meter 10 is normal in combination with whether the total mileage displayed by the combination meter 10 is normal.
In a third aspect, the embodiment of the invention provides a heavy truck, as shown in fig. 3, the heavy truck 20 comprises a plurality of controllers 4 belonging to different communication networks and the combination meter 10 provided in the above embodiment.
The combination meter 10 is connected to a plurality of controllers 4. Therefore, on the basis of the functions of the combination meter 10, the requirement of each controller of the whole vehicle on the gateway function can be met by expanding the routing function and the node monitoring function and according to a certain routing strategy, namely the implementation method of the heavy truck gateway provided by the embodiment, and the cooperative coordination of each controller of the whole vehicle system and the network monitoring of each controller are realized.
