The invention provides a data transmission method and a data transmission system for a mobile terminal and a vehicle-mounted system. The method comprises the steps of selecting a connected physical channel between the mobile terminal and the vehicle-mounted system to serve as a transmission negotiation channel, performing data interaction between the mobile terminal and the vehicle-mounted system via the transmission negotiation channel, transmitting a channel detection command, detecting each connected physical channel between the mobile terminal and the vehicle-mounted system, and acquiring a communication performance parameter of each connected physical channel; making a judgment according to real-time communication performance of the communication performance parameter on each physical channel to determine a preferential physical channel; and automatically switching data to be transmitted between the mobile terminal and the vehicle-mounted system to be transmitted to the preferential physical channel for transmission. Therefore, the interconnection channel between the vehicle-mounted system and the mobile terminal is more flexible, more brands and types of vehicle-mounted systems and the mobile terminals are adaptive, meanwhile, the connection is more robust, and the available connection is still kept in the environment with interference by switching the channel.
Description
technical field [0001] The present invention relates to the technical field of in-vehicle systems, in particular to a data transmission method between a mobile terminal and an in-vehicle system, and a data transmission system between a mobile terminal and an in-vehicle system. Background technique [0002] The interconnection between mobile terminals and in-vehicle systems is an important development direction of the smart Internet of Vehicles, which can quickly and conveniently migrate Internet services based on mobile terminals to automotive application scenarios. [0003] The core technology of the interconnection between the mobile terminal and the vehicle system is to transmit the video, audio, control signals and other data on the mobile terminal to the vehicle system, and transmit the control signals generated by the vehicle system to the mobile terminal to complete the interactive function. The interconnection technology between mobile terminals and vehicle systems e...
