Audio frequency playing method for vehicle-mounted terminal, vehicle-mounted terminal, mobile terminal and vehicle

Abstract

The embodiment of the invention provides an audio frequency playing method for a vehicle-mounted terminal, the vehicle-mounted terminal, a mobile terminal and a vehicle, and belongs to the technical field of the vehicle-mounted terminal. The audio frequency playing method for the vehicle-mounted terminal is used for the vehicle-mounted terminal and comprises the following steps that: determining the mobile terminal which is simultaneously communicated with the vehicle-mounted terminal through Bluetooth and a USB (Universal Serial Bus) interface; sending an audio frequency data communication strategy to the determined mobile terminal to enable the mobile terminal which receives the audio frequency data communication strategy to carry out audio frequency data communication with the vehicle-mounted terminal through the USB interface; via the USB interface, receiving the audio frequency data from the mobile terminal; and playing the received audio frequency data. Through the above technical scheme, when the vehicle-mounted terminal and the mobile terminal are communicated simultaneously through the Bluetooth and the USB interface, the audio frequency data can be communicated only through the USB interface to realize high-quality audio frequency output.

Description

technical field [0001] The present invention relates to the field of in-vehicle technology, and in particular, relates to an in-vehicle audio playback method, an in-vehicle, a mobile terminal and a vehicle. Background technique [0002] At present, with the rapid development of car-machine technology and smart phone technology, there are more and more interconnection solutions between car-machine and smart phone. Generally, compared with smart phones, car phones have a larger display screen, which is convenient for drivers to watch, while smart phones have more functions than car phones. Therefore, interconnecting the car machine and the smartphone through a communication interface can bring a better user experience. [0003] Cars and smartphones are generally connected wirelessly via Bluetooth or wired via a USB interface. [0004] However, the inventors of the present application found in the process of realizing the present invention that if the car machine, such as a n...
