DATA TRANSMISSION BY INTELLIGENT COCKPIT SYSTEM

The disclosure relates to the field of communication technologies, and specifically provides a data transmission method, apparatus, a vehicle system, and a medium, for meeting a data transmission demand of a heterogeneous intelligent cockpit system. To this end, according to the disclosure, the data transmission method can be used by a cockpit domain functional unit of a heterogeneous intelligent cockpit system, where the heterogeneous intelligent cockpit system further includes a multimedia system functional unit, and the cockpit domain functional unit and the multimedia system functional unit are heterogeneously arranged. The method includes: determining one or more communication services with the multimedia system functional unit based on a communication transmission requirement with the multimedia system functional unit; establishing one or more communication channels to the multimedia system functional unit based on content of the one or more communication services, where the one or more communication channels are corresponding to the one or more communication services; and matching a communication service from the one or more communication services and invoking a communication channel from the one or more communication channels for data transmission, in response to a received transmission demand instruction from an upper-layer application, where the communication service and the communication channel are corresponding to the received transmission demand instruction.
