Vehicle-mounted message transmission method, device and system

Abstract

The invention discloses a vehicle-mounted message transmission method, and the method comprises the following steps: receiving message data sent by a sending end, wherein the message data comprises message contents and message types, and the message types comprise category values and sub-classification values; verifying the category value and the sub-classification value through a preset information verification rule, and determining that the message content is legal when determining that the corresponding relationship between the category value and the sub-classification value is consistent with the information verification rule; after determining that the message content is legal, processing the message content according to the message type. According to the technical scheme, corresponding sub-classification values are distributed to different message types on the basis of the field of vehicle-mounted information entertainment products, and the sub-classification values in the message data are verified in the information verification rule after the vehicle-mounted information entertainment products receive the message data, so the legality of the message content is determined; the content legality of the vehicle information center is ensured, and different notifications and reminding messages are safely sent to the information center.

Description

Technical field [0001] The present invention relates to the field of vehicle information processing, and more particularly to an in-vehicle messaging method, apparatus, and system. Background technique [0002] The vehicle message center is a channel that connects the user and the vehicle system operator in the in-vehicle operating system, and each car system application can pass the notification, reminder and other information in real time through the message center. With the increasing number of messages of the vehicle message center, the message content transmitted on the message channel is increasing, and the vehicle system is a closed environment requires a high environment. [0003] However, in the art, the strategy for transmitting information content for the vehicle messaging information in the art is that the transmitting end is sent to the vehicle machine by the transmitting end, and the vehicle system is a type of message through the message species (TYPE) defined in t...

Problems solved by technology

[0003] However, the current strategy for the vehicle-machine message center to transmit information content in this technical field is that the sending end sends it to the vehicle-machine in a general way, and the vehicle-machine system uses the message type value (type) defined in the message protocol to carry out certain types of messages. identification and distinction, and present the recognized message content on the vehicle, and the vehicle system will not over-control the content of the message. This approach will have the following problems: 1. The sender can send different messages at will. 2. It is difficult to subdivide, control and statistically analyze different message contents; 3. It is difficult to implement different interaction schemes or special processing for different messages

as follows figure 1 As shown, the type value of the traffic message is 6, and the type value of the smart home message is 13. If the car machine receives the type 6 and 13, it will consider it legal and display it. Then, the traffic module and the smart home will create new messages spontaneously. And pass in the corresponding value, it can be easily recognized, the vehicle side cannot control the legitimacy of the new message, there is a certain risk here
