Based on the decoupled publish and subscribe mode between the MQTT client and server, the car end and the cloud gateway between the car end and the cloud server can realize the car cloud data channel based on multiple network channels, and the car end publishes messages through the car cloud data channel to The cloud, or the car end subscribes to the cloud to send control messages, but if multiple data messages share a car cloud channel network resource, such as remote control command messages, the timeliness requirements are high, and the data volume of the car end will increase with the business expansion. Expansion, data accumulation takes up a lot of resources, which may lead to a relatively large delay in the response of the car control and affect the user experience. It is necessary to adjust the data configuration of the car-cloud network channel according to the requirements of business indicators such as delay and traffic.

Messages are exchanged between the car end and the cloud gateway between the car end and the cloud server. The network channel configuration data currently adopts the method of issuing configuration instructions through the diagnostic device. The diagnostic device sends DID setting instructions to the car end, and the car end gateway receives the configuration. The data is successfully executed, and based on the updated configuration, the updated data response is sent to the cloud. Usually, the diagnostic device sends the diagnostic settings and needs to be manually triggered to control the specific vehicle.

However, there are some deficiencies in the existing method for setting the diagnostic DID through the diagnostic device:

Since the control command is sent to the car end through the diagnostic equipment, the car end receives and stores the changed network channel configuration rules, which need to be specific to a single car, which not only occupies storage space but also does not apply to batch car control;

At the same time, because the manual trigger is used to send the diagnostic command to the bicycle, the operation is time-consuming and laborious; at the same time, the vehicle receives the cloud control change command, and needs to reset and re-initialize the program to make the specific configuration change take effect.
