[0046] Figure 5 is a flowchart of the vehicle-mounted screen cleaning method according to the embodiment of the application. As shown in Figure 5 The vehicle-mounted screen cleaning method according to the embodiment of the application comprises the following steps S501-S503: S501, generating a screen cleaning instruction for the vehicle-mounted screen 700 when the screen cleaning condition is met. The screen cleaning condition can be determined by the execution subject of the embodiment of the application itself or by the user. For example, when the user thinks that there are many stains on the current vehicle screen 700 and cleaning is needed, the screen cleaning condition can be confirmed by voice instruction or trigger button.

[0047] In step S502, according to the above screen cleaning instruction, the vehicle screen 700 is turned off, and after the vehicle screen 700 is turned off, the screen cleaning instruction is sent to the controller 500 of the vehicle screen cleaning device, so that the vehicle screen cleaning device cleans the vehicle screen 700. In the case of receiving the screen cleaning instruction, in order to prevent misoperation during cleaning of the vehicle screen 700, the vehicle screen 700 can be temporarily turned off, so that the vehicle screen 700 is black and enters the lock screen mode. Then, the screen cleaning instruction is sent to the controller 500 of the vehicle screen cleaning device.

[0048] In step S503, in response to the completion of cleaning of the vehicle screen 700, the vehicle screen 700 is turned on.

[0049] After identifying that the vehicle screen cleaning device completes the cleaning of the vehicle screen 700, the vehicle screen 700 can be turned on, so that the vehicle screen 700 starts to work normally.

[0050] In an optional embodiment of the application, the method further comprises: acquiring a vehicle screen image by an image acquisition device, and performing image recognition on the vehicle screen image; and in response to the image recognition result indicating that the first proportion of the dirty area to the total area of the vehicle screen 700 is greater than or equal to a first proportion threshold or the second proportion of the number of dirty-shielded texts to the total number of texts in the vehicle screen 700 is greater than or equal to a second proportion threshold, it is determined that the screen cleaning condition is met.
