Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The invention provides a gateway controller route configuration method, a device, equipment and an automobile, aiming at the problem of high load rate on a T-BUS.
As shown in fig. 1, an embodiment of the present invention provides a method for configuring a gateway controller route, including:
and 11, acquiring a message cycle threshold value on a pre-configured remote control high-speed BUS T-BUS.
And step 12, acquiring the message cycle of the remote vehicle-mounted terminal T-BOX message to be forwarded to the T-BUS.
And step 13, judging the relation between the message period and the message period threshold value.
The embodiment of the invention enables the message cycle forwarded to the T-BUS to be more than or equal to the message cycle threshold when the T-BOX message is forwarded by pre-configuring the message cycle threshold on the T-BUS, thereby reducing the load rate on the T-BUS and ensuring the function of the T-BOX. When the T-BOX uploading and storage period are changed, only the configuration word of the gateway controller is required to be modified, and the gateway controller software is not required to be modified, so that the cost and period of software modification and test are reduced, the OEM can be autonomously configured, higher initiative is provided, and meanwhile, the strategy information of providing the T-BOX for a supplier is reduced, so that the effect of confidentiality is achieved to a certain extent.
It should be noted that, a preconfigured message cycle threshold on the T-BUS may be dynamically adjusted by receiving, by the gateway controller, a message sent by the UDS, so before step 11, the method further includes:
and setting the message cycle threshold value on the T-BUS according to a message sent by a Unified Diagnosis Service (UDS).
Specifically, the setting of the message cycle threshold on the T-BUS according to a message sent by a unified diagnostic service UDS includes:
entering an extension mode and feeding back a message which enters the extension mode according to the message which enters the extension mode and is sent by the UDS;
and receiving a write-in threshold message sent by the UDS, setting a message period threshold according to configuration word information in the write-in threshold message, and feeding back the successfully written-in threshold message.
It should be noted that a preset number may be pre-stored in the gateway controller as a DID, for example, the number is 0C04, and the UDS sends the DID to the gateway to execute a corresponding operation, specifically including a write operation, a read operation, and the like, for example, 2E is the write operation, and 22 is the read operation, so that when a message includes 2E 0C04 XX, it indicates that a cycle threshold in a message sent by the UDS is written, and when a message includes 220C 04 XX, it indicates an operation of reading the cycle threshold of the message, where XX is a specific value of the cycle threshold of the message.
It should be further noted that, when it is required to set the message period threshold to be 100ms, the following messages may be set according to the above method, where the data width of the configuration word may be set to be 1 byte:
the UDS sends a first message to a gateway controller: 0x7DF 021003 XX, particularly for controlling gateway controller function addressing into an extension mode.
The gateway controller sends a second message to the UDS: the 0x7BE 025003 XX is specifically used for responding to entering an extension mode after the gateway controller enters the extension mode according to a first message sent by the UDS.
The UDS sends a third message to the gateway controller: 0x7B 6052E 0C 0404000000, specifically configured to control the gateway controller to write a message period threshold of 100 ms.
The UDS sends a fourth message to the gateway controller: 0x7BE 036E 0C04 XX, which is specifically used for responding to a successful writing of a message cycle threshold after the gateway controller writes the cycle threshold according to a third message sent by the UDS.
It should be noted that X is any hexadecimal data, where it is determined to enter the extension mode is 021003, and since the length of the message byte is 8, the role of X is to fill the placeholder, which is not practical.
Specifically, for the configuration word information, the access right thereof may also be set, and specifically, the access right may include that the security level right is not needed, the security level right needs to be extended, the security level right needs to be programmed, the response service is not supported, and the like.
The embodiment of the invention dynamically controls the period of the gateway controller for forwarding the message by the mode of modifying the configuration word, and can obtain the optimal period threshold value through testing, thereby not only ensuring the T-BOX function, but also optimizing the baud rate to the maximum extent.
It should be noted that, the message routing refers to a routing form of forwarding a data field of a frame of message from a source network segment to a target network segment without any change; the signal routing is a routing form for recombining the signals in one or more frames of messages of the source network segment and then transmitting the signals to the target network segment.
Specifically, when the T-BOX packet is forwarded, forwarding is performed in a signal routing manner or a packet routing manner.

Specifically, the apparatus further comprises:
and the setting module is used for setting the message cycle threshold value on the T-BUS according to the message sent by the UDS.
Specifically, the setting module includes:
the first processing unit is used for entering an extension mode and feeding back a message which enters the extension mode according to the message which enters the extension mode and is sent by the UDS;
and the second processing unit is used for receiving the writing threshold message sent by the UDS, setting a message period threshold according to configuration word information in the writing threshold message and feeding back the successfully written threshold message.
Specifically, when the T-BOX packet is forwarded, forwarding is performed in a signal routing manner or a packet routing manner.
An embodiment of the present invention further provides a gateway controller route configuration device, including: the gateway controller routing configuration method comprises a memory, a processor and a computer program stored on the memory and capable of running on the processor, wherein the processor executes the computer program to realize the gateway controller routing configuration method.

It should be noted that, the car provided with the gateway controller route configuration device can make the message cycle forwarded to the T-BUS be more than or equal to the message cycle threshold when the T-BOX message is forwarded by configuring the message cycle threshold on the T-BUS in advance, thereby reducing the load rate on the T-BUS and ensuring the function of the T-BOX. When the T-BOX uploading and storage period are changed, only the configuration word information of the gateway controller is required to be modified, and the gateway controller software is not required to be modified, so that the cost and period of software modification and test are reduced, the OEM can be autonomously configured, higher initiative is provided, and meanwhile, the strategy information of providing the T-BOX for a supplier is reduced, so that the effect of confidentiality is achieved to a certain extent.
