[0046] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0047] See also Figures 1 to 3 The present invention proposes a control method, system, device and medium for a vehicle-mounted central control screen, which can be applied to the driving field of artificial intelligence. The vehicle-mounted central control system can have reasonable startup efficiency and resource allocation by learning and analyzing user behavior data in the vehicle cabin.

[0048] See also Figure 1 In one embodiment of the present invention, the present invention provides a control method for a vehicle-mounted central control, which may include the following steps.

[0049] Step S10: When the main display screen and the auxiliary display screen of the vehicle are turned on, the working state of the main display screen is detected.

[0050] Step S20: When the main display screen is in an abnormal working state, the operating frequency of the auxiliary display screen is detected within a preset time.

[0051] Step S30: when the operating frequency of the secondary display screen is less than a preset threshold frequency, first configuration information is generated and displayed on the primary display screen; an operating instruction input by the driver for the first configuration information on the primary display screen is received, and the secondary display screen is controlled.

[0052] Step S40: When the operating frequency of the secondary display screen is greater than or equal to a preset threshold frequency, second configuration information is generated according to the priority of the application on the main display screen and / or the priority of the application on the secondary display screen; based on the second configuration information, the application on the main display screen and / or the application on the secondary display screen is controlled.

[0053] The following is a detailed description through specific embodiments.

[0054] Step S10: When the main display screen and the auxiliary display screen of the vehicle are turned on, the working state of the main display screen is detected.

[0055] Specifically, after the vehicle is powered on, the instrument system in the vehicle is started first, and the central control system is turned on normally. The central control system can control the output of the vehicle's main display screen and the output of the secondary display screen. Among them, for the output of the main display screen and the output of the secondary display screen, the output content may include a hardware part and a software part. The hardware part may be the display frame rate of the main display screen and / or the secondary display screen, graphics card load information (graphics card usage rate per unit time), etc. The software part may be the display interface on the main display screen and / or the secondary display screen, and the application (APP, APPlication) associated with the display interface, etc. The main display screen is close to the main driver's seat, and the secondary display screen is close to the secondary driver's seat.

[0056] Specifically, when both the main display screen and the secondary display screen are using high computing power and rendering at a high frame rate, the main display screen may have insufficient computing power or display frame drops. At this time, the main display screen and the secondary display screen need to be adjusted to ensure that the computing power corresponding to the main display screen is normal or the display does not drop frames. For example, the display frame rate of the vehicle's main display screen is obtained, and the display frame rate of the main display screen is compared with the preset threshold frame rate. When the display frame rate of the main display screen is less than the preset threshold frame rate, it can be considered that the computing power of the graphics processor (GPU, Graphics Processing Unit) corresponding to the main display screen is too high, and the computing power of the main display screen is insufficient or the display frame drops, that is, the working state of the main display screen is abnormal.

[0057] Step S20: When the main display screen is in an abnormal working state, the operating frequency of the auxiliary display screen is detected within a preset time.

[0058] Specifically, when the display frame rate of the main display screen is less than the threshold frame rate, that is, the main display screen is considered to have insufficient computing power or display frame loss in an abnormal working state, the computing power corresponding to the main display screen can be ensured to be normal or display frame loss can be ensured by turning off the secondary display screen. As for whether the secondary display screen needs to be turned off, it is also necessary to determine whether there is a passenger in the front passenger seat, or to determine the passenger's need to use the secondary display screen.

[0059] Specifically, within a preset time, the operating frequency of the secondary display screen is detected. When the operating frequency of the secondary display screen is less than a preset threshold frequency, there may be no passenger on the front passenger seat, or there may be a passenger on the front passenger seat but no need to use the secondary display screen. As to whether there is a passenger on the front passenger seat, the gravity on the front passenger seat may be detected by a pressure sensor to determine whether there is a passenger on the front passenger seat.

[0060] Step S30: when the operating frequency of the secondary display screen is less than a preset threshold frequency, first configuration information is generated and displayed on the primary display screen; an operating instruction input by the driver for the first configuration information on the primary display screen is received, and the secondary display screen is controlled.

[0061] Specifically, when the main display screen is working abnormally and the operating frequency of the secondary display screen is less than a preset threshold frequency, the secondary display screen can usually be turned off, so the first configuration information for turning off the secondary display screen can be generated and displayed on the main display screen. Even if there is no passenger on the front passenger seat, if the secondary display screen is turned off directly, the driver may mistakenly think that the secondary display screen is malfunctioning while driving, so it is necessary to display the first configuration information for turning off the secondary display screen on the main display screen.

[0062] Step S40: When the operating frequency of the secondary display screen is greater than or equal to a preset threshold frequency, second configuration information is generated according to the priority of the application on the main display screen and / or the priority of the application on the secondary display screen; based on the second configuration information, the application on the main display screen and / or the application on the secondary display screen is controlled.

[0063] Specifically, when the main display screen is working abnormally and the operating frequency of the secondary display screen is greater than or equal to the preset threshold frequency, the secondary display screen cannot be turned off directly. In order to ensure that the computing power corresponding to the main display screen is normal or the display does not drop frames, consider shutting down some applications (APPs) on the main display screen and / or the secondary display screen in the background.

[0064] For example, based on the priority of the application on the main display screen and / or the priority of the application on the secondary display screen, the second configuration information for closing some applications on the main display screen and / or closing applications on the secondary display screen may be generated. Based on the second configuration information, the application on the main display screen and / or the application on the secondary display screen may be controlled.

[0065] In addition, when the working status of the main display screen is normal, it is considered that the computing power corresponding to the main display screen is normal or the display does not drop frames. At this time, no adjustment is required, and the main display screen and the sub-display screen can be kept turned on.

[0066] See also Figure 1 In one embodiment of the present invention, in step S30, when the operating frequency of the secondary display screen is less than a preset threshold frequency, first configuration information is generated and displayed on the main display screen; the step of receiving an operating instruction input by the driver for the first configuration information on the main display screen and controlling the secondary display screen may include step S310, step S320 and step S330.

[0067] Step S310: When the operating frequency of the secondary display screen is less than a preset threshold frequency, first configuration information for closing the secondary display screen is generated and displayed on the primary display screen.

[0068] Step S320: receiving a closing instruction input by the driver for the first configuration information on the main display screen, and closing the secondary display screen.

[0069] Step S330: receiving the driver's input of the opening instruction for the first configuration information on the main display screen, and keeping the secondary display screen turned on.

[0070] Specifically, the first configuration information for closing the secondary display screen is sent to the driver. The advantage is that if the secondary display screen needs to be closed, the secondary display screen can be closed after the driver agrees. If the driver is driving to pick up passengers, the secondary display screen does not need to be closed. If the driver disagrees, the secondary display screen cannot be closed.

[0071] See also Figure 1 In one embodiment of the present invention, after step S330, after receiving the driver's input of the first configuration information on the main display screen to turn on the first configuration information, the step of keeping the secondary display screen turned on may include step S331 and step S332.

[0072] Step S331: Generate third configuration information according to the priority of the application on the main display screen and / or the priority of the application on the secondary display screen.

[0073] Step S332: based on the third configuration information, close some applications on the main display screen and / or some applications on the secondary display screen.

[0074] Specifically, when the main display screen is working abnormally, and the operating frequency of the secondary display screen is less than the preset threshold frequency, and after the driver's input of disagreement is accepted and the secondary display screen is kept turned on, the secondary display screen cannot be turned off directly. In order to ensure that the computing power corresponding to the main display screen is normal or the display does not drop frames, it is possible to consider closing some applications (APP, APPlication) on the main display screen and / or the secondary display screen in the background.

[0075] See also Figure 1 In one embodiment of the present invention, when the working state of the main display screen is abnormal and when the operating frequency of the sub-display screen is greater than or equal to a preset threshold frequency, in step S40, the step of generating the second configuration information according to the priority of the application on the main display screen and / or the priority of the application on the sub-display screen may include step S410, step S420 and step S430.

[0076] Step S410: Generate main screen configuration information for closing low-priority applications according to the priorities of the applications on the main display screen.

[0077] Step S420: Generate secondary screen configuration information for closing low-priority applications according to the priorities of the applications on the secondary display screen.

[0078] Step S430: Combine the main screen configuration information and / or the sub-screen configuration information to obtain second configuration information.

[0079] On the main display screen and the secondary display screen, the secondary display screen usage rate U PSD ,satisfy Among them, T CSD Main display operating frequency, T PSD is the operating frequency of the secondary display screen, A non-zero constant that is adjusted based on the idle time of the secondary display.

[0080] On the main display screen and the secondary display screen, the priority level of different applications is P i ,satisfy Among them, L n is the number of startups corresponding to the nth application, d n is the total usage time corresponding to the nth application, n is the total number of applications, ω1 and ω2 are weight parameters, and the number of startup times is L APP ={L1,L2,...,L n}, the total usage time set is D APP ={d1,d2,...,d n}.

[0081] See also Figure 1 In one embodiment of the present invention, in step S10, the step of detecting the working state of the main display screen includes step S110, step S120 and step S130.

[0082] Step S110, obtaining the graphics card load information of the main display screen, and comparing the graphics card load information with a preset threshold usage rate; wherein the graphics card load information is expressed as a graphics card usage rate per unit time.

[0083] Step S120: When the graphics card load information is less than the threshold usage rate, it is determined that the working state of the main display screen is abnormal.

[0084] Step S130: When the graphics card load information is greater than or equal to the threshold usage rate, it is determined that the main display screen is in a normal working state.

[0085] Specifically, when the graphics card load information is greater than or equal to the threshold usage rate, it can be considered that the usage functions of the main display and the secondary display can be met, and no adjustment is required, and the main display and the secondary display can be kept turned on. When the graphics card load information is less than the threshold usage rate, it can be considered that the usage functions of the main display and the secondary display cannot be met, and adjustments need to be made. In order to ensure that the computing power corresponding to the main display is normal or the display does not drop frames, you can consider turning off the secondary display, or closing some applications (APP, APPlication) on the main display and / or the secondary display in the background.

[0086] See also Figure 1 In one embodiment of the present invention, in step S10, the step of detecting the working state of the main display screen includes step S111, step S121 and step S131.

[0087] Step S111: acquiring the display frame rate of the main display screen, and comparing the display frame rate of the main display screen with a preset threshold frame rate.

[0088] Step S121: When the display frame rate of the main display screen is less than the threshold frame rate, it is determined that the working state of the main display screen is abnormal.

[0089] In step S131, when the display frame rate of the main display screen is greater than or equal to the threshold frame rate, it is determined that the working state of the main display screen is normal.
