Problems solved by technology

However, this method has a high threshold for in-vehicle systems and mobile phones, few supported mobile phones, low image transmission efficiency, and poor image fluency
[0004] Moreover, because the display and operation are multiplexed in one transmission channel, it not only affects the transmission efficiency, but also increases the complexity of software optimization and reduces the user experience.
[0005] In addition, smart phones now have rich interface configurations. Generally, usb and bluetooth are standard configurations. Some smart phones are also equipped with HDMI interfaces. A problem with smartphone apps

Abstract

The invention discloses a method for mirroring from a smart phone to a vehicle-mounted system. The smart phone and a vehicle-mounted device are included. The method is characterized by comprising the steps as follows: a) the smart phone and the vehicle-mounted device are connected through an independent display channel and an interactive channel respectively; b) a display content is mirrored in a vehicle-mounted screen through the display channel by the phone; and c) operations are mirrored in the smart phone through the interactive channel by the vehicle-mounted device. The method has the benefits as follows: the system cost is reduced, the mirroring efficiency is improved, and software system optimization is simplified.

Description

technical field [0001] The invention relates to a method for mirroring a mobile phone, in particular to a method for mirroring a smart phone and a vehicle-mounted system. Background technique [0002] Since 2007, China's car navigation market has entered a period of rapid development. It has changed from a luxury item selected on high-end models to a must-have item for car owners today. At the same time, the inherent weaknesses of traditional car navigation are becoming increasingly apparent: high hardware costs, inability to access the Internet, untimely update of map data, and cumbersome after-sales services for dealers. Mobile phone navigation just makes up for these shortcomings, but the mobile phone screen is small, the volume is low, and the operation is inconvenient. How to output the image and sound on the mobile phone to the vehicle system in real time has become the object of everyone's research. [0003] MirrorLink is a smart and car navigation connection meth...
