In addition, in the embodiment of the present invention, after the audio host is switched from the pre-operating mode to the shutdown mode, when the audio host detects a trigger signal of a switch key of the audio system, the audio host is switched from the shutdown mode to the pre-operating mode again, that is, when a user triggers a Power key, the audio host can be switched to the pre-operating mode again, and at this time, the audio host is directly switched from the shutdown mode to the pre-operating mode without playing a startup animation.
With reference to fig. 1 and fig. 2, in the embodiment of the present invention, in order to further predict the user behavior, so as to further improve the user experience, after the step S103, the method further includes:

In this embodiment, no matter whether the sound host detects the ACC hard line signal change first and then detects the door open signal, or detects the door open signal first and then detects the ACC hard line signal change, the sound host can switch from the sound normal operating mode to the shutdown mode, and when the whole vehicle is further detected to sleep, the sound host can also switch from the shutdown mode to the sleep mode, so that when the user needs to leave, the sound system can be shut down without active operation, thereby further improving the user experience.
In the embodiment of the invention, after the sound host is switched back to the shutdown mode from the pre-working mode or the normal working mode, when the sound host detects that the ACC hard wire signal is switched to the high level signal again from the low level signal, the sound host is directly switched to the normal working mode from the shutdown mode. In the specific implementation, after the main audio unit is switched back to the shutdown mode from the pre-operation mode or the normal operation mode, the user can directly operate the key gear to the ACC gear or the ON gear, so that the main audio unit is switched from the shutdown mode to the normal operation mode without switching the main audio unit to the pre-operation mode and then to the normal operation mode. In addition, after the main audio unit is switched back to the shutdown mode from the pre-operation mode or the normal operation mode, when the main audio unit is further switched to the sleep mode from the shutdown mode and then switched to the shutdown mode from the sleep mode, the user can also switch the main audio unit from the shutdown mode to the normal operation mode by directly operating the key gear to the ACC gear or the ON gear without switching the main audio unit to the pre-operation mode and then to the normal operation mode.
In addition, after the sound host is switched back to the shutdown mode from the sleep mode, the pre-working mode or the normal working mode, when a user triggers the Power key, the sound host can be switched to the pre-working mode again.
Referring to fig. 1 and fig. 2, in the embodiment of the present invention, in order to avoid excessive use of the battery power, after step S103, the method further includes:

In a specific implementation, when the main audio unit is in the normal operating mode, and when a user triggers a Power key, the main audio unit is switched from the normal operating mode to the screen saver mode, at this time, the audio system displays a screen saver interface (such as only displaying a clock, no sound output, and the like), and when the user switches the key gear from the ACC gear or the ON gear to the OFF gear, the main audio unit is switched from the screen saver mode to the OFF mode.
In addition, when the audio main unit detects that the ACC hard wire signal is switched back to a high level signal from a low level signal, the audio main unit is switched back to the screen saver mode from the power-OFF mode, namely, when a user switches the key gear position from the OFF gear position to the ACC gear position or the ON gear position, the audio main unit can be switched back to the screen saver mode from the power-OFF mode.
In the embodiment of the invention, after the sound host is switched from the normal working mode or the shutdown mode to the screen saver mode, when the sound host detects the activation request signal, the sound host is switched back to the normal working mode from the screen saver mode; the activation request signal comprises one or more of a Bluetooth Call request signal, an activation request signal of a panoramic image system, a trigger signal of a switch key of an audio system, an E-Call request signal and a B-Call request signal. Specifically, the activation request signal of the panoramic image system includes a key trigger signal and a reverse signal of the panoramic image system, and a user can activate the panoramic image system through a key of the panoramic image system or a reverse operation. When the activation request signal is the activation request signal of the panoramic image system, the sound host is switched to the screen saver mode again from the normal working mode when the sound host detects that the panoramic image system exits from the activation state. In specific implementation, when the audio host is in the screen saver mode, when a user activates the panoramic image system through a key of the panoramic image system or a reversing operation, the audio host is switched from the screen saver mode to the normal operating mode, and when the panoramic image system exits from the activation state, the audio host is switched from the normal operating mode to the screen saver mode again. In addition, when the main audio unit is in the screen saver mode, when the user performs a bluetooth Call or an E-Call (emergency rescue) or a B-Call (road rescue) (the E-Call or the B-Call is denoted as E/B-Call in the figure), the main audio unit is switched from the screen saver mode to the normal operation mode, and after the user finishes the Call, the main audio unit can be kept in the normal operation mode, so that the user can continue to use the audio system. In addition, in the embodiment of the invention, the user can also switch the sound host between the screen saver mode and the normal working mode through the Power key.
