In addition to setting the bit rate value in this embodiment, the user also selects the mode in the connection mode option area M; the user clicks on the ok button N after selecting, the processor 102 saves the setting parameters, and then exits the third interface Y. In this embodiment, the connection mode option area M displays three preset connection modes for the user to select, including a USB connection mode, a WIFI connection mode, and a WIFI fallback connection mode. Of course, this is only a better practice example of the present embodiment and is not limiting. In some embodiments, the connection mode option area M displays other connection modes for user selection, for example, in some embodiments, the connection mode option area M provides a bluetooth connection mode for selection. The WIFI connection mode in this embodiment means that only the touch screen 103 picture of the android phone 10 is projected onto the display screen 202 of the in-vehicle device through WIFI, and the user cannot operate and control the android phone 10 on the in-vehicle device 20; the WIFI connection mode is characterized in that a function of controlling the android mobile phone 10 on the car machine 20 is added on the basis of WIFI connection, the mobile phone needs to be connected with a USB line for activation operation after the connection mode is selected, and the USB line can be pulled out after the activation is successful.
A specific implementation of processor 102 when the user selects the WIFI fallback connection mode in connection mode option area M is illustrated in fig. 6. Firstly, judging whether a WIFI back control connection mode is selected, if so, popping up a dialog box prompting a user to deactivate, selecting whether to activate by the user, if not, returning to a third interface Y, and selecting other connection modes by the user. And if the user selects activation, judging whether the activation is performed or not, and if the activation is performed, clicking the determination button N to exit the third interface Y. If not, whether the USB line between the android mobile phone 10 and the car machine 20 is connected is judged, and because the USB line between the android mobile phone 10 and the car machine 20 is required to be connected in the activation process and the network is also required to be used, whether the network is connected is also judged. And when the conditions are met, entering an activation progress bar interface and sending a request for activating the vehicle-mounted machine back control operation to the vehicle-mounted machine screen throwing service program. And circularly detecting whether the activation is successful or not, directly returning to the third interface Y if the activation is successful, otherwise, returning to the third interface Y if the activation is failed after 15 seconds, and prompting the user that the activation is unsuccessful on the third interface Y, such as popping up a prompt box or other manners, without limitation.
