[0002] Currently, in-vehicle information systems are becoming increasingly powerful and their screens are getting larger, gradually becoming standard equipment in cars. While these systems bring convenience to people, they are also gradually becoming a major source of interference in the vehicle, especially when driving at night. When the screen brightness of the in-vehicle information system is too bright, it can seriously interfere with the driver's vision and create driving safety hazards. When the screen brightness is too dim, the driver cannot easily see the content on the screen and needs to get closer to the screen or manually adjust the screen brightness to a suitable level, which also poses a safety hazard.

[0023] Optionally, controlling the backlight of the current in-vehicle screen through the virtual host manager based on the backlight arbitration result includes:

[0024] The virtual host manager generates backlight adjustment commands for each screen in the current vehicle screen based on the backlight arbitration results.

[0063] When the current vehicle screen is detected to be in screen saver mode, the cumulative duration of the current vehicle screen being in screen saver mode is monitored in real time.

[0064] When the accumulated time reaches a preset accumulated time threshold, the screen dimming event monitored by the operating system is obtained, and the screen dimming event is fed back to the backlight arbitration module under the vehicle virtualization architecture.

[0065] The backlight arbitration module performs backlight arbitration on the current vehicle screen.

[0066] The device of the present invention calls the automatic screen-off program under the vehicle virtualization architecture stored in the memory 1005 through the processor 1001, and also performs the following operations:

[0067] The backlight arbitration module determines the brightness parameters of the current vehicle screen and generates the backlight arbitration results of each screen in the current vehicle screen according to the brightness parameters, a preset screen backlight switch logic table, and a preset priority.

[0068] The backlight arbitration module sends the backlight arbitration result to the backlight control module under the vehicle virtualization architecture.

[0070] The virtual host manager generates backlight adjustment commands for each screen in the current vehicle screen based on the backlight arbitration results.

[0071] The backlight control module under the vehicle virtualization architecture uses the backlight adjustment command to control the backlight drive module under the vehicle virtualization architecture.

[0072] The backlight driving module controls and adjusts the backlight of each screen.

[0073] The device of the present invention calls the automatic screen-off program under the vehicle virtualization architecture stored in the memory 1005 through the processor 1001, and also performs the following operations:

[0074] The backlight driver module controls the serializer to turn off the backlight of the target screen, and controls and adjusts the corresponding screen according to the backlight adjustment command.

[0075] This embodiment, through the above-described scheme, performs backlight arbitration on the current vehicle screen when it is detected to be in screensaver mode under the vehicle virtualization architecture; controls the backlight of the current vehicle screen according to the backlight arbitration result through the virtual host manager; and completes the screen-off operation when the backlight of the current vehicle screen is detected to be off. This effectively analyzes the backlight situation of each vehicle screen, performs precise backlight control and adjustment for each vehicle screen, and directly controls the vehicle screen under the vehicle virtualization architecture, improving the accuracy of vehicle screen backlight adjustment and increasing the speed and efficiency of automatic screen-off under the vehicle virtualization architecture.

[0076] Based on the above hardware structure, an embodiment of the automatic screen-off method under the vehicle virtualization architecture of the present invention is proposed.

[0077] Reference Figure 2 , Figure 2This is a flowchart illustrating the first embodiment of the automatic screen-off method under the vehicle virtualization architecture of the present invention.

[0078] In the first embodiment, the automatic screen-off method under the vehicle virtualization architecture includes the following steps:

[0079] Step S10: When it is detected that the current vehicle screen under the vehicle virtualization architecture is in screen saver mode, backlight arbitration is performed on the current vehicle screen.

[0080] It should be noted that the laser point cloud data is the point cloud data generated after scanning the top surface of the bridge pier with a laser. The laser point cloud data is preprocessed to obtain the preprocessed target point cloud data.

[0081] Step S20: Control the backlight of the current vehicle screen through the virtual host manager according to the backlight arbitration result.

[0082] It should be understood that after cropping the target point cloud data according to the pre-set planar region, a planar equation can be fitted. The planar equation refers to the equation corresponding to all points in space that are on the same plane, and its general form is Ax+By+Cz+D=0.

[0083] Step S30: When the backlight of the current vehicle screen is detected to be off, the screen-off operation of the current vehicle screen is completed.

[0084] It is understood that the planar distance between the straightedge plane and all planes in the preset planar area can be calculated through the planar equation, and the flatness detection result of the top surface of the bridge pier can be generated based on the planar distance.

[0085] This embodiment, through the above-described scheme, performs backlight arbitration on the current vehicle screen when it is detected to be in screensaver mode under the vehicle virtualization architecture; controls the backlight of the current vehicle screen according to the backlight arbitration result through the virtual host manager; and completes the screen-off operation when the backlight of the current vehicle screen is detected to be off. This effectively analyzes the backlight situation of each vehicle screen, performs precise backlight control and adjustment for each vehicle screen, and directly controls the vehicle screen under the vehicle virtualization architecture, improving the accuracy of vehicle screen backlight adjustment and increasing the speed and efficiency of automatic screen-off under the vehicle virtualization architecture.

[0086] Furthermore, Figure 3 This is a flowchart illustrating the second embodiment of the automatic screen-off method under the vehicle virtualization architecture of the present invention, as shown below. Figure 3 As shown, based on the first embodiment, a second embodiment of the automatic screen-off method under the vehicle virtualization architecture of the present invention is proposed. In this embodiment, step S10 specifically includes the following steps:

[0087] Step S11: When the operating system of the current vehicle screen under the vehicle virtualization architecture is started and the current vehicle screen is displayed normally, the operating system is monitored in real time.

[0088] It should be noted that when the operating system of the current in-vehicle screen under the in-vehicle virtualization architecture is detected to be starting up and the current in-vehicle screen is displaying normally, the operating system can be monitored in real time.

[0089] Step S12: Control the current vehicle screen to be in screen saver mode according to the monitoring data of the operating system.

[0090] It is understandable that screen saver detection can be performed using monitoring data from the operating system, and the current in-vehicle screen can be controlled to be in screen saver mode based on the monitoring data from the operating system.

[0091] Step S13: When the current vehicle screen is detected to be in screen saver mode, backlight arbitration is performed on the current vehicle screen according to the backlight arbitration module under the vehicle virtualization architecture.

[0092] It should be understood that the in-vehicle virtualization architecture includes a backlight arbitration module. When the current in-vehicle screen is in screen saver mode, the backlight arbitration module can be used to arbitrate the backlight of the current in-vehicle screen.

[0093] This embodiment, through the above-described scheme, performs backlight arbitration on the current vehicle screen when it is detected to be in screensaver mode under the vehicle virtualization architecture; controls the backlight of the current vehicle screen according to the backlight arbitration result through the virtual host manager; and completes the screen-off operation when the backlight of the current vehicle screen is detected to be off. This effectively analyzes the backlight situation of each vehicle screen, performs precise backlight control and adjustment for each vehicle screen, and directly controls the vehicle screen under the vehicle virtualization architecture, improving the accuracy of vehicle screen backlight adjustment and increasing the speed and efficiency of automatic screen-off under the vehicle virtualization architecture.

[0094] Furthermore, Figure 4 This is a flowchart illustrating the third embodiment of the automatic screen-off method under the vehicle virtualization architecture of the present invention, as shown below. Figure 4 As shown, based on the second embodiment, a third embodiment of the automatic screen-off method under the vehicle virtualization architecture of the present invention is proposed. In this embodiment, step S12 specifically includes the following steps:

[0095] Step S121: When the monitoring data indicates that the operating system receives a control command within a preset screen saver judgment time, execute the control command.

[0096] It should be noted that when the monitoring data indicates that the operating system receives a control command within a preset screen saver judgment time, the control command can be executed.

[0097] Step S122: When the monitoring data indicates that the operating system has not received the control command within the preset screen saver judgment time, the system controls the current vehicle screen to enter screen saver mode.

[0098] It is understood that when the monitoring data shows that the operating system does not receive the control command within the preset screen saver judgment time, it can control the current vehicle screen to be in screen saver mode. The control command is generally generated by the user through voice, touch, button, gesture, image recognition, etc. Of course, it can also be generated through other methods, such as head movements such as nodding or shaking the head to generate different control commands. It can also be generated through a mobile APP or smart key. This embodiment does not limit this.

[0099] In a specific implementation, the preset screen saver judgment time can be set to 10 minutes. For example, if the user does not perform any operation parameter control commands on the current vehicle screen within 10 minutes, the current screen can be put into screen saver mode. Of course, the preset screen saver judgment time can also be set to other values, such as 5 minutes or 60 seconds. This embodiment does not limit this.

[0100] This embodiment, through the above-described scheme, executes the control command when the monitoring data indicates that the operating system receives the control command within the preset screen saver judgment time; and controls the current vehicle screen to be in screen saver mode when the monitoring data indicates that the operating system does not receive the control command within the preset screen saver judgment time. This allows the current vehicle screen to be in screen saver mode even when no control command is received, effectively analyzing the backlight situation of each vehicle screen and improving the speed and efficiency of automatic screen-off under the vehicle virtualization architecture.

[0101] Furthermore, Figure 5 This is a flowchart illustrating the fourth embodiment of the automatic screen-off method under the vehicle virtualization architecture of the present invention, as shown below. Figure 5 As shown, based on the second embodiment, a fourth embodiment of the automatic screen-off method under the vehicle virtualization architecture of the present invention is proposed. In this embodiment, step S13 specifically includes the following steps:

[0102] Step S131: When the current vehicle screen is detected to be in screen saver mode, monitor the cumulative duration of the current vehicle screen being in screen saver mode in real time.

[0103] It should be noted that when the current vehicle screen is detected to be in screen saver mode, the cumulative duration of the current vehicle screen in screen saver mode can be monitored in real time, that is, the cumulative duration of the screen in screen saver mode can be obtained.

[0104] Step S132: When the accumulated time reaches a preset accumulated time threshold, obtain the screen dimming event monitored by the operating system, and feed the screen dimming event back to the backlight arbitration module under the vehicle virtualization architecture.

[0105] It is understood that when the accumulated duration reaches a preset accumulated duration threshold, the screen dimming event monitored by the operating system can be obtained, and then the screen dimming event can be fed back to the backlight arbitration module under the vehicle virtualization architecture.

[0106] In a specific implementation, the preset cumulative duration threshold can be set to 2 minutes. That is, after the screen enters the screen saver, the screen kernel will report a screen dimming event, and then report the screen dimming event to the backlight arbitration module. The preset cumulative duration threshold can also be set to other values, such as 1 minute, 3 minutes or 5 minutes, etc. This embodiment does not limit this.

[0107] Step S133: Perform backlight arbitration on the current vehicle screen through the backlight arbitration module.

[0108] It should be understood that the backlight arbitration module can perform backlight arbitration on the current vehicle screen.

[0109] Furthermore, step S133 specifically includes the following steps:

[0110] The backlight arbitration module determines the brightness parameters of the current vehicle screen and generates the backlight arbitration results of each screen in the current vehicle screen according to the brightness parameters, a preset screen backlight switch logic table, and a preset priority.

[0111] The backlight arbitration module sends the backlight arbitration result to the backlight control module under the vehicle virtualization architecture.

[0112] It should be noted that the in-vehicle virtualization architecture includes a backlight arbitration module, a backlight control module, and a backlight driver module. The backlight arbitration module can determine the brightness parameters of the current in-vehicle screen, and generate the backlight arbitration results of each screen in the current in-vehicle screen according to the brightness parameters, a pre-set screen backlight switch logic table, and a pre-set priority. The backlight arbitration module can send the backlight arbitration results to the backlight control module under the in-vehicle virtualization architecture.

[0113] In the specific implementation, according to the preset screen backlight switch logic table and priority rules, each sequence number can be checked in turn to see if it meets the screen backlight switch judgment method. The sequence number corresponding to the screen backlight switch state that needs to be controlled with the highest priority is obtained, and then it is determined what state the backlight of each screen should be in. The backlight arbitration result is sent to the backlight control module under the vehicle virtualization architecture through the backlight arbitration module, so as to achieve accurate control of the screen backlight.

[0114] This embodiment, through the aforementioned scheme, determines the brightness parameters of the current vehicle screen via the backlight arbitration module, and generates backlight arbitration results for each screen in the current vehicle screen according to the brightness parameters, based on a preset screen backlight switch logic table and preset priority. The backlight arbitration results are then sent to the backlight control module under the vehicle virtualization architecture via the backlight arbitration module. This enables backlight adjustment of the vehicle screen without going through the backlight control module, improving the accuracy of backlight adjustment and increasing the speed and efficiency of automatic screen-off under the vehicle virtualization architecture.

[0115] Furthermore, Figure 6 This is a flowchart illustrating the fifth embodiment of the automatic screen-off method under the vehicle virtualization architecture of the present invention, as shown below. Figure 6 As shown, based on the first embodiment, a fifth embodiment of the automatic screen-off method under the vehicle virtualization architecture of the present invention is proposed. In this embodiment, step S30 specifically includes the following steps:

[0116] Step S31: Generate backlight adjustment commands for each screen in the current vehicle screen based on the backlight arbitration result through the virtual host manager.

[0117] It should be noted that the virtual machine host manager can generate corresponding backlight adjustment commands for each screen in the current vehicle screen based on the backlight arbitration results.

[0118] In practical implementation, in the in-vehicle environment, there are usually multiple screens, such as the instrument panel screen, the central control screen, and the passenger screen. If the backlight control of these screens is independent of each other, problems such as asynchronous switching and chaotic status may occur, which will affect the user experience. By using the backlight arbitration result, the orderly and unified management of the backlight of multiple screens can be achieved, avoiding situations such as asynchronous backlight switching and undefined backlight switch status.

[0119] Step S32: The backlight control module under the vehicle virtualization architecture controls the backlight drive module under the vehicle virtualization architecture using the backlight adjustment command.

[0120] It is understood that the backlight control module can control the backlight driver module to adjust the backlight, that is, the backlight control module under the vehicle virtualization architecture can use the backlight adjustment command to control the backlight driver module under the vehicle virtualization architecture.

[0121] Step S33: Control and adjust the backlight of each screen through the backlight driving module.

[0122] It should be understood that the backlight driver module can control and adjust the backlight of each screen in the vehicle screen accordingly.

[0123] Furthermore, step S33 specifically includes the following steps:

[0124] The backlight driver module controls the serializer to turn off the backlight of the target screen, and controls and adjusts the corresponding screen according to the backlight adjustment command.

[0125] It is understood that the backlight driving module can control the serializer to turn off the backlight of the target screen, and then control and adjust the corresponding screen according to the backlight adjustment command.

[0126] In the specific implementation, see Figure 7 , Figure 7 This is a schematic diagram of the vehicle virtualization architecture in the automatic screen-off method under the vehicle virtualization architecture of the present invention, as shown below. Figure 7 As shown, taking a Windows-based in-vehicle system as an example, the virtual host manager can control and drive the backlight. The in-vehicle Windows system can report screen dimming events through the kernel, perform backlight arbitration through the backlight arbitration module, and control the serializer to turn off the target screen's backlight through the backlight driver module, thereby achieving automatic screen-off of the Windows screen under the in-vehicle virtualization architecture. Specifically, if Windows does not receive an event for 10 minutes, it will activate the screen saver. After 2 minutes, the Windows kernel can detect the screen dimming and send it to the Windows backlight arbitration through an interface. The Windows backlight arbitration then sends the dimming status to the backlight control through inter-virtual machine communication, and the backlight control turns off the backlight. Of course, in addition to Windows, in-vehicle systems can also be Android, Apple CarPlay, Google Android Auto, QNX, and Linux, etc. This embodiment does not limit this.

[0127] This embodiment, through the above-described scheme, generates backlight adjustment commands for each screen in the current vehicle-mounted screen based on the backlight arbitration result through the virtual host manager; the backlight control module under the vehicle virtualization architecture uses the backlight adjustment commands to control the backlight driver module under the vehicle virtualization architecture; and the backlight driver module controls and adjusts the backlight of each screen. This effectively analyzes the backlight situation of each vehicle-mounted screen, performs precise backlight control and adjustment, and directly controls the vehicle-mounted screens under the vehicle virtualization architecture, improving the accuracy of backlight adjustment and increasing the speed and efficiency of automatic screen-off under the vehicle virtualization architecture.

[0128] Accordingly, the present invention further provides an automatic screen-off device under an in-vehicle virtualization architecture.

[0129] Reference Figure 8 , Figure 8 This is a functional block diagram of the first embodiment of the automatic screen-off device under the vehicle virtualization architecture of the present invention.

[0130] In the first embodiment of the automatic screen-off device under the vehicle virtualization architecture of the present invention, the automatic screen-off device under the vehicle virtualization architecture includes:

[0131] The detection module 10 is used to perform backlight arbitration on the current vehicle screen when it is detected that the current vehicle screen under the vehicle virtualization architecture is in screen saver mode.

[0132] The adjustment module 20 is used to control the backlight of the current vehicle screen through the virtual host manager based on the backlight arbitration result.
