[0002] With the rapid development of smart car technology, in-vehicle information systems are becoming more and more complex and diverse. Modern in-vehicle information systems are not only equipped with basic video recording functions, but also integrate advanced functions such as blind spot detection systems (BSD) and weather display. Therefore, there is a demand for more efficient and intuitive information display and control methods for in-vehicle information systems. When some in-vehicle systems are used while driving, users need to use their mobile phones for navigation and use the car computer to record driving images. At the same time, the car computer also has functions such as music playback. When users need to answer a call while driving, they need to switch the display interface between multiple screens, resulting in safety hazards during the user's driving process.

[0003] It is difficult for the current in-vehicle operating system to achieve multi-screen display. Most of the current in-vehicle operating systems are composed of a dual system architecture of QNX system and Android system. The vehicle image information is displayed by the QNX system, and the multimedia and car machine applications are displayed by the Android system. At present, the Android system cannot achieve split-screen display with the QNX system image information area at the system level, that is, the current in-vehicle operating system can only display the interface corresponding to a single system function, and cannot display the interfaces corresponding to multiple functions at the same time, such as the navigation page and the vehicle information page, resulting in a poor user experience and bringing safety hazards to the user's driving process.

[0029] The current in-vehicle operating system can only display the interface corresponding to a single system function, and cannot display the interfaces corresponding to multiple functions at the same time. For example, it cannot display the navigation page and the vehicle information page, resulting in a poor user experience and posing safety hazards to the user's driving process.

[0030] Based on the above reasons, the embodiment of the present application provides a split-screen display control method for an in-vehicle operating system, the method comprising: obtaining a display area parameter of the in-vehicle display screen and a first display size parameter of the in-vehicle navigation image, determining a second display size parameter according to the first display size parameter, and determining a first layer according to the first display size parameter, and determining a second layer according to the second display size parameter, and displaying the first layer and the second layer in sequence from top to bottom on the in-vehicle display screen; wherein the first layer is used to display the in-vehicle navigation image, and the second layer is used to display the in-vehicle multimedia image; in response to the driving event information of the vehicle, the first display size parameter and the second display size parameter are updated, and the first layer is updated based on the updated first display size parameter, and the second layer is updated based on the updated second display size parameter. The method in the embodiment of the present application can dynamically control the in-vehicle navigation image and the in-vehicle multimedia image, realize the dynamic update of the in-vehicle navigation image and the in-vehicle multimedia image, improve the display effect and use experience of the in-vehicle navigation image and the in-vehicle multimedia image, and can improve the safety of the user in driving.

[0031] In some scenarios, a split-screen display control method of an in-vehicle operating system of an embodiment of the present application can be applied to the in-vehicle operating system, which can improve the control effect of the display function of the in-vehicle operating system.

[0032] The following is a detailed description of a split-screen display control method for an in-vehicle operating system provided in an embodiment of the present application with reference to specific examples.

[0033] Figure 1 A schematic diagram of the flow chart of the first split-screen display control method of the vehicle-mounted operating system provided in the embodiment of the present application is shown as follows: Figure 1 As shown, the method includes S110 to S120, and S110 to S120 are described in detail below.

[0034] S110, obtaining a display area parameter of the vehicle display screen and a first display size parameter of the vehicle navigation image, determining a second display size parameter according to the first display size parameter, determining a first layer according to the first display size parameter, and determining a second layer according to the second display size parameter, and displaying the first layer and the second layer in sequence from top to bottom on the vehicle display screen. The first layer is used to display the vehicle navigation image, and the second layer is used to display the vehicle multimedia image.

[0035] When the method controls the display process of the vehicle operating system, the display area parameters of the vehicle display screen and the first display size parameters of the vehicle navigation image can be first obtained. The display area parameters may include display size information of the vehicle display screen, and the first display size parameters of the vehicle navigation image include display size information of the vehicle navigation image. Then, the display of the vehicle operating system can be controlled according to the display area parameters and the first display size parameters of the vehicle navigation image.

[0036] Exemplarily, the first display size parameter of the in-vehicle navigation image may be an original display size parameter of the in-vehicle navigation image.

[0037] Exemplarily, the display area parameter may include display size information of a full-screen display of the vehicle-mounted display screen, or may be a display image of a partial display area of ​​the vehicle-mounted display screen.

[0038] When controlling the display process of the vehicle operating system, the second display size parameter can be determined according to the first display size parameter, and the first layer can be determined according to the first display size parameter, and the second layer can be determined according to the second display size parameter. The first layer and the second layer are respectively used to display different images, thereby realizing display control of different display areas.

[0039] Figure 2 A schematic diagram of a display interface controlled by a split-screen display control method of an in-vehicle operating system provided in an embodiment of the present application, such as Figure 2 As shown, after determining that the display area parameters can include the full-screen display area 1 of the vehicle display screen, and after determining the first layer 11 and the second layer 12, the first layer 11 and the second layer 12 can be displayed sequentially from top to bottom on the vehicle display screen, thereby enabling control of the display effects of the first layer 11 and the second layer 12.

[0040] When displaying, the first layer is determined by the first display size parameter of the vehicle navigation image, so that the first layer is used to display the vehicle navigation image, and the second layer is used to display the vehicle multimedia image, so that the first layer and the second layer can display the vehicle navigation image and the vehicle multimedia image independently of each other.

[0041] Exemplarily, the in-vehicle navigation image may be a display interface corresponding to the navigation software.

[0042] Exemplarily, the in-vehicle multimedia image may be a video, audio, or game operation interface displayed by the in-vehicle multimedia software.

[0043] S120. In response to the driving event information of the vehicle, update the first display size parameter and the second display size parameter, and update the first layer based on the updated first display size parameter and update the second layer based on the updated second display size parameter.

[0044] During the display process of the vehicle operating system, the first display size parameter and the second display size parameter can be updated in response to the driving event information of the vehicle. The first display size parameter and the second display size parameter are used to control the display effects of the first layer and the second layer. The first layer can be updated based on the updated first display size parameter, and the second layer can be updated based on the updated second display size parameter. The display process of the first layer and the second layer can be controlled, thereby improving the display effect of the vehicle operating system.

[0045] The beneficial effect of the above-mentioned implementation method is that it can dynamically control the vehicle navigation image and the vehicle multimedia image, realize the dynamic update of the vehicle navigation image and the vehicle multimedia image, improve the display effect and usage experience of the vehicle navigation image and the vehicle multimedia image, and can improve the safety of users while driving.

[0046] The beneficial effect of the above-mentioned implementation method is that it can dynamically adjust the in-vehicle navigation display image and the in-vehicle multimedia image, avoid the experience of a fixed display area brought about by the existing fixed display of the in-vehicle navigation display image and the in-vehicle multimedia image on the vehicle system, and improve the display effect of the in-vehicle operating system.

[0047] In some implementations, in the above S120, in response to the driving event information of the vehicle, the first display size parameter and the second display size parameter are updated, including: when the vehicle is in a deceleration state or a turning state, the first display size parameter is increased and the second display size parameter is decreased. When the vehicle is in a constant speed state, an acceleration state or a reverse state, the first display size parameter is decreased and the second display size parameter is increased.

[0048] During the driving process of the vehicle, when the vehicle is in a deceleration state or a turning state, it means that the vehicle driver may have a higher demand for the on-board navigation at this time. At this time, the first display size parameter can be increased and the second display size parameter can be reduced. Correspondingly, the display area of ​​the first layer corresponding to the first display size parameter can be increased, and the display area of ​​the second layer corresponding to the second display size parameter can be reduced. This can improve the display effect of the navigation information when the vehicle is in a deceleration state or a turning state, thereby improving the vehicle driving experience and safety.

[0049] Exemplarily, when the vehicle is in a deceleration state or a turning state, the deceleration state or the turning state of the vehicle can be acquired by a gyroscope or an accelerometer of the vehicle.

[0050] During the driving process of the vehicle, when the vehicle is in a constant speed state, an accelerating state or a reversing state, it means that the vehicle driver may have a low demand for the in-vehicle navigation at this time. At this time, the first display size parameter can be reduced and the second display size parameter can be increased. Correspondingly, the display area of ​​the first layer corresponding to the first display size parameter can be reduced, and the display area of ​​the second layer corresponding to the second display size parameter can be increased. This can improve the display effect of multimedia information when the vehicle is in a constant speed state, an accelerating state or a reversing state, and improve the multimedia visual experience during vehicle driving.

[0051] For example, when the vehicle is in a constant speed state, an accelerating state, or a reversing state, the constant speed state, the accelerating state, or the reversing state of the vehicle can be acquired through a vehicle gyroscope, an accelerometer, or a driving information system.

[0052] The beneficial effect of the above implementation method is that it can improve the display effect of navigation information when the vehicle is in a deceleration state or a turning state, thereby improving the vehicle driving experience and safety.

[0053] The beneficial effect of the above implementation method is that it can improve the display effect of multimedia information when the vehicle is in a constant speed state, an acceleration state or a reversing state, and improve the multimedia visual experience during vehicle driving.

[0054] Figure 3 A flow chart of a second split-screen display control method for a vehicle-mounted operating system provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, in the above S110, determining the second display parameter according to the first display parameter includes S111 to S112, and S111 to S112 are specifically described below.

[0055] S111. Acquire driving state information of the vehicle, and determine a driving state factor corresponding to the driving state information.

[0056] During the operation of the vehicle operating system, the vehicle operating system may start to display only when the vehicle is driving, or the multimedia system of the vehicle operating system may start to work. Then, the display interface of the vehicle operating system can be initialized or updated when the vehicle operating system starts to display.

[0057] When initializing or updating the display interface of the vehicle operating system, the vehicle's driving status information can be obtained, and then the display status of the vehicle display screen can be updated according to the driving status information, thereby improving the display experience when initializing or updating the display interface of the vehicle operating system.

[0058] When the display state of the vehicle display screen is initialized or updated according to the driving state information, the driving state factor corresponding to the driving state information can be determined, and then the display state of the vehicle display screen can be updated according to the driving state factor.

[0059] Exemplarily, the driving state factor may be determined by a preset empirical value table.

[0060] S112: Acquire original display size parameters of the vehicle navigation image, use the product of the original display size parameters and the driving state factor as a first display size parameter, and use the difference between the display area parameter and the first display size parameter as a second display size parameter.

[0061] When the display status of the vehicle display screen is initialized or updated according to the driving status information, the original display size parameters of the vehicle navigation image can be obtained, and then the product of the original display size parameters and the driving status factor can be used as the first display size parameter, thereby initializing or updating the display status of the vehicle display screen according to the driving status information, thereby improving the display effect of the vehicle navigation image.

[0062] After the first display size parameter is obtained, the difference between the display area parameter and the first display size parameter may be used as the second display size parameter, and the vehicle-mounted multimedia image may be displayed according to the second display size parameter.

[0063] The beneficial effect of the above-mentioned implementation method is that the vehicle-mounted operating system may start displaying only during vehicle driving, or the multimedia system of the vehicle-mounted operating system starts working. When the vehicle-mounted operating system starts displaying, the display interface of the vehicle-mounted operating system is initialized or updated, which can improve the display experience of the vehicle-mounted overload system.

[0064] The beneficial effect of the above-mentioned implementation method is that by determining the driving state factor corresponding to the driving state information, the display state of the vehicle display screen can be updated according to the driving state factor, thereby improving the display effect of initializing or updating the display state of the display screen according to the driving state information.

[0065] In some implementations, the above method also includes: obtaining the mean of the first display size parameter manually set by the user corresponding to similar historical driving state information, and determining the ratio of the mean of the manually set first display size parameter to the original display size parameter as a driving state factor.

[0066] When the vehicle-mounted operating system starts to display, the display interface of the vehicle-mounted operating system is initialized or updated, and the average value of the first display size parameter manually set by the user corresponding to similar historical driving state information can be obtained. The first display size parameter manually set by the user corresponding to similar historical driving state information is the record value of the first display size parameter set by the user in the historical data. By obtaining the average value of the first display size parameter manually set by the user corresponding to similar historical driving state information, the display interface of the vehicle-mounted operating system can be initialized or updated according to the first display size parameter selected by the user in the driving state information in the historical state, thereby improving the effect of initializing or updating the display interface of the vehicle-mounted operating system.

[0067] Exemplarily, when obtaining the mean of the first display size parameter manually set by the user corresponding to similar historical driving state information, the historical driving state information whose difference between the historical driving state information is within a preset range can be regarded as the same historical driving state information, so as to increase the amount of sample data while retaining a reasonable error between the sample data.

[0068] After obtaining the mean of the first display size parameters manually set by the user corresponding to the same historical driving status information, the ratio of the mean of the manually set first display size parameters to the original display size parameters can be determined as a driving status factor, and then the display status of the vehicle-mounted operating system can be updated according to the driving status factor during the subsequent initialization or update of the display interface of the vehicle-mounted operating system, so that the effect of initializing or updating the display interface of the vehicle-mounted operating system is more in line with the user's historical usage habits, thereby improving the user's usage experience.

[0069] The beneficial effect of the above-mentioned implementation method is that by obtaining the average of the first display size parameters manually set by the user corresponding to the same historical driving status information, the display interface of the vehicle operating system can be initialized or updated according to the first display size parameters selected by the user in the historical driving status information, thereby improving the user's personalized usage experience.

[0070] In some implementations, the ratio of the mean of the manually set first display size parameter to the original display size parameter is determined, including: when the first display size parameter is not changed within a preset first time period after the user manually sets the first display size parameter, and when a fluctuation value of the vehicle's driving state information within the preset first time period is less than a preset fluctuation value, determining the mean of the first display size parameter manually set by the user within the preset first time period as the mean of the first display size parameter manually set by the user corresponding to similar historical driving state information.

[0071] When obtaining the mean value of the first display size parameter manually set by the user corresponding to similar historical driving state information, if the first display size parameter is not changed within a preset first time period after the user manually sets the first display size parameter, and the driving state information fluctuation value of the vehicle within the preset first time period is less than the preset fluctuation value, the mean value of the first display size parameter manually set by the user within the preset first time period is used as the mean value of the first display size parameter manually set by the user corresponding to the similar historical driving state information, so as to ensure the accuracy of the mean value of the first display size parameter manually set by the user corresponding to the similar historical driving state information.

[0072] Exemplarily, the preset first time period may be 1 minute, 3 minutes or 5 minutes.

[0073] Exemplarily, by determining the fluctuation value of the driving state information of the vehicle within a preset first time period, the fluctuation values ​​of specific parameters such as acceleration and steering angle in the driving state information of the vehicle within the preset first time period can be obtained.

[0074] Exemplarily, the preset fluctuation value may be 20%, 30% or 40%.

[0075] The beneficial effect of the above-mentioned implementation method is that after the user manually sets the first display size parameter, the first display size parameter is not changed within the preset first time period, and when the fluctuation value of the vehicle's driving status information within the preset first time period is less than the preset value, the mean value of the first display size parameter manually set by the user within the preset first time period is determined as the mean value of the first display size parameter manually set by the user corresponding to similar historical driving status information, thereby improving the reliability of the mean value of the first display size parameter manually set by the user corresponding to similar historical driving status information and enhancing the user experience.

[0076] Figure 4 A flow chart of a third method for controlling split-screen display of a vehicle-mounted operating system provided in an embodiment of the present application is shown as follows: Figure 4 As shown, the above method further includes S210 to S220, and S210 to S220 are described in detail below.

[0077] S210, obtaining an interval driving state factor corresponding to the driving state information of the vehicle in a preset second time period, and obtaining an adjustment driving state factor corresponding to the driving state information of the vehicle in a preset third time period at the end of the preset second time period.

[0078] The method in the embodiment of the present application may also introduce an adaptive driving state factor adjustment mechanism when controlling the display state. Specifically, it may perform dynamic adjustments according to vehicle speed, lane keeping, and driving behavior (such as sudden braking, sharp turns, etc.), so that the display size parameters may be more in line with the requirements of the actual driving environment.

[0079] In this method, an interval driving state factor corresponding to the driving state information of the vehicle within a preset second time period can be obtained, and the driving state information within the preset second time period is the historical driving state information of the vehicle. An adjusted driving state factor corresponding to the driving state information of the vehicle within a preset third time period at the end of the preset second time period can be obtained, and the driving state information within the preset third time period is the adjusted driving state information of the vehicle. Then, the driving state factor can be adaptively adjusted according to the interval driving state factor and the adjusted driving state factor.

[0080] Exemplarily, the preset second time period may be a historical time period of 1 minute, 3 minutes or 5 minutes starting from the current moment.

[0081] Exemplarily, the preset third time period may be a time period corresponding to 20% to 30% of the end of the preset second time period.

[0082] Exemplarily, when obtaining the interval driving state factor corresponding to the driving state information of the vehicle in the preset second time period, the interval driving state factor corresponding to the average value of the driving state information of the vehicle in the preset second time period can be determined through an experience value table.

[0083] Exemplarily, the adjusted driving state factor may be determined by a change value of the driving state information and an experience value table corresponding to the adjusted driving state factor.

[0084] S220, obtaining original display size parameters of the vehicle navigation image, taking the product of the original display size parameter, the interval driving state factor and the adjusted driving state factor as a first display size parameter, and taking the difference between the display area parameter and the first display size parameter as a second display size parameter.

[0085] After obtaining the interval driving state factor and the adjusted driving state factor, the original display size parameter of the vehicle navigation image can be obtained, and the product of the original display size parameter, the interval driving state factor and the adjusted driving state factor is used as the first display size parameter, thereby realizing adaptive adjustment of the driving state factor according to the interval driving state factor and the adjusted driving state factor.

[0086] When determining the second display size parameter, a difference value obtained by subtracting the first display size parameter from the display area parameter may be used as the second display size parameter.

[0087] The beneficial effect of the above-mentioned implementation method is that the interval driving state factor corresponding to the driving state information of the vehicle in the preset second time period represents the overall value of the vehicle's driving state in the second time period, and the adjustment driving state factor corresponding to the driving state information of the vehicle in the preset third time period at the end of the preset second time period represents the change information of the vehicle's driving state at the end of the second time period, and then the display state of the vehicle's on-board operating system can be adaptively adjusted through the interval driving state factor and the adjustment driving state factor, so that the display effect is more adapted to the user's operation process, thereby improving the user's driving experience.

[0088] The beneficial effect of the above-mentioned implementation method is that the product of the original display size parameter, the interval driving state factor and the adjusted driving state factor is used as the first display size parameter, and the display state of the vehicle's on-board operating system is adaptively adjusted through the interval driving state factor and the adjusted driving state factor, thereby improving the user experience of the display state of the on-board operating system.

[0089] An embodiment of the present application also provides a split-screen display control system of an in-vehicle operating system, comprising a unit for executing any of the methods described above.

[0090] Figure 5 A schematic diagram of the logical structure of a split-screen display control system of a vehicle-mounted operating system provided in one embodiment of the present application is shown in FIG. Figure 5 As shown, the system 2 of this embodiment includes a processing unit 21, a storage unit 22 and a transceiver unit 23.
