[0059] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application, and are not used to limit the present application.

[0060] In order to better understand the technical solutions of the present application, the following will be described in detail in conjunction with the drawings and specific embodiments of the specification.

[0061] The main solution of the embodiment of the present application is: in response to a process running request of a vehicle display screen, a target process corresponding to the process running request is pulled up; the current working temperature of the vehicle display screen is obtained; the current available computing power of the processor of the vehicle display screen is determined according to the current working temperature; the target process is controlled based on the current available computing power, and the computing power occupation of the target process to the processor is reduced.

[0062] Since the prior art mainly uses hardware-level thermal management design to ensure the heat dissipation capacity of the car machine, so that the processor works at a suitable temperature, but this way is not obvious enough in high temperature environment, the temperature in the car is still very high, the performance of the car machine is lower than the normal value, the cold start time of the car machine will be longer, and even the extreme scene will appear lag. Moreover, the number of applications in the car machine is large, each application is a function implementation party and a function provider (exposes a function interface to other application calls), at the product definition level, each application is designed to call the function interface of the other party, resulting in that during cold start, the car machine starts to pull up application A, A uses other application BC interface, which will cause application B, C process to be pulled up, and finally all applications will be pulled up, the cold start time of the car machine is long, and the high overall car machine load during use will cause use lag and other abnormalities.

[0063] The present application provides a solution to optimize the temperature scene, consider the actual computing power of the processor, and thus adjust the process in real time to ensure user experience and system smoothness.

[0064] It should be noted that the execution subject of the present embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle display screen performance management device, etc. The vehicle display screen performance management device is taken as an example to illustrate the present embodiment and the following embodiments.

[0065] Based on this, the present application embodiment provides a vehicle display screen performance management method, referring to Figure 1 , Figure 1 The flowchart of the first embodiment of the vehicle display screen performance management method of the present application.

[0066] In the present embodiment, the vehicle display screen performance management method comprises steps S10-S40:

[0067] Step S10: in response to a process running request of a vehicle display screen, a target process corresponding to the process running request is pulled up.

[0068] It should be noted that the process running request of the vehicle display screen can be initiated by the user through voice or directly triggered on the vehicle display screen, and the process running request is the running request of one or more application programs in the vehicle display screen. The process running request can also come from the internal automatic scheduling demand of the system, such as the start of a timing task or a background service.

[0069] After responding to the process running request, a preset strategy can be used to determine how to start the target process. The preset strategy process running includes process priority sorting, process startup timing, resource allocation principles, inter-process dependency handling, and process startup security checks, etc. For example, if a high-priority interactive application is requested, CPU and memory resources are allocated preferentially, and the process is ensured to be successfully started in a short time, while if a low-priority background service is requested, a more energy-saving startup strategy can be adopted, such as delayed startup or limiting its resource usage.

[0070] Step S20: Obtain the current working temperature of the vehicle display screen.

[0071] In a specific implementation, since the working temperature of the vehicle display screen is one of the important factors affecting the performance of the processor. If there are many target processes to be started or the resources occupied by the target processes to be started are more, the temperature can be higher, so the current working temperature of the vehicle display screen can be collected in real time by a temperature sensor or the like.

[0072] Step S30: Determine the current available computing power of the processor of the vehicle display screen according to the current working temperature.

[0073] It should be noted that the current available computing power of the processor of the vehicle display screen can be determined according to the current working temperature, for example, the current available computing power of the processor of the vehicle display screen is calculated according to the current working temperature, or a corresponding relationship between the working temperature and the actual computing power of the processor is established in advance, so that the current available computing power of the processor corresponding to the current working temperature is directly obtained according to the corresponding relationship. Since the performance of the processor will decrease as the working temperature increases, the current available computing power of the processor of the vehicle display screen can be determined by a preset temperature-computing power curve or model and the current working temperature.

[0074] The current available computing power of the processor is the computing capability that the central processing unit (CPU) can provide in the current application scenario.

[0075] In a feasible implementation, a corresponding relationship between the temperature of the vehicle display screen and the computing power of the processor can be established in advance, so before step S30, steps A11-A14 are further included:

[0076] Step A11: Set a plurality of constant working temperature points and collect the number of processor cores when the vehicle display screen is running.

[0077] In a specific implementation, different working temperature points can be calibrated by constant temperature testing, so as to obtain a plurality of constant working temperature points. For example, 20℃, 30℃, 40℃, etc.

[0078] In a specific implementation, the number n of CPU cores can be collected through a dedicated testing tool or software.

[0079] Step A12: At each operating temperature point, corresponding processor frequency data is collected.

[0080] It should be noted that the vehicle display can be started and a specific program can be run at each operating temperature point to record the changes in processor frequency when the vehicle display is running at the corresponding temperature, including the highest frequency, lowest frequency and average frequency.

[0081] like Figure 2 As shown, Figure 2 The figure below shows the processor frequency data of the vehicle display at the operating temperature T0. The CPU frequency changes differently at different time points. The processor frequency over a period of time can be counted to obtain the minimum processor frequency F_min.

[0082] Step A13: Calculate the historical actual computing power data of the processor based on the minimum frequency of the processor in the processor frequency data and the number of processor cores.

[0083] It should be noted that the stable CPU computing power of the processor at different operating temperatures can be calculated based on the CPU frequency and the number of processor cores n, thereby obtaining the historical actual computing power data of the processor. The historical actual computing power of the processor is calculated as follows:

[0084] ∑F=F_min*n

[0085] In the above formula, ∑F is the processor's historical actual computing power data, n is the number of processor cores, and F_min is the processor's minimum frequency. This gives the processor's actual processing power under different temperature environments.

[0086] Step A14: establishing a relationship between the operating temperature of the vehicle display screen and the actual computing power of the processor based on the historical actual computing power data and the operating temperature point, and obtaining a vehicle display screen temperature-processor computing power curve.

[0087] In a specific implementation, the corresponding relationship between the operating temperature of the vehicle display and the actual computing power of the processor can be established based on the calculated historical actual computing power data and the corresponding operating temperature data. By fitting and displaying it in the form of a chart or curve, the vehicle display temperature-processor computing power curve can be obtained, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the vehicle display temperature-processor computing power curve. The vehicle display temperature-processor computing power curve can intuitively understand the processor performance of the vehicle display in different temperature environments.

[0088] In a specific implementation, based on the vehicle display screen temperature-processor computing power curve established based on the above content, step S30 can include: querying the vehicle display screen temperature-processor computing power curve according to the current working temperature to obtain the current available computing power of the processor of the vehicle display screen corresponding to the current working temperature.

[0089] It should be noted that the current available computing power of the processor corresponding to the current working temperature can be obtained by querying the vehicle display screen temperature-processor computing power curve according to the current working temperature of the vehicle display screen, for example, when the current working temperature is 25℃, the actual CPU computing power corresponding to 25℃ on the vehicle display screen temperature-processor computing power curve is 2GHz.

[0090] Step S40: controlling the target process based on the current available computing power to reduce the computing power occupation of the target process on the processor.

[0091] In a specific implementation, after determining the current available computing power of the processor, the target process needs to be controlled according to the computing power to reduce the computing power occupation of the target process on the processor and improve the performance of the vehicle display screen. The specific control strategy can include limiting the running speed of the process, adjusting the priority of the process, suspending or terminating the low-priority process, etc. Through these control strategies, the process running on the vehicle display screen can be adjusted in real time to adapt to different working scenarios and user needs.

[0092] The embodiment provides a vehicle display screen performance management method, which responds to a process running request of a vehicle display screen, starts a target process corresponding to the process running request; obtains a current working temperature of the vehicle display screen; determines a current available computing power of a processor of the vehicle display screen according to the current working temperature; controls the target process based on the current available computing power to reduce the computing power occupation of the target process on the processor. By responding to the process running request of the vehicle display screen, when starting the target process, the priority, running time and other resource allocation of the target process are dynamically adjusted according to the actual computing power of the processor, it can be ensured that the vehicle display screen can maintain the best performance in different working scenarios, and the user experience is improved.

[0093] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar content as the above embodiment one can refer to the above introduction, and the following will not be repeated. On this basis, please refer to Figure 4 , step S40 includes steps S401-S403:

[0094] Step S401: obtaining a current running state of the target process.

[0095] It should be noted that the current running state of the target process may include a startup state and a running state, and the running state includes foreground running or background running.

[0096] Step S402: determining the processor performance occupancy data corresponding to the target process according to the current running state and the relationship between the process running state and the process processor performance occupancy.

[0097] It should be understood that the relationship between the process running state and the process's processor performance utilization is used to describe the processor performance utilization of processes in different running states. After determining the current running state of the target process, the processor performance utilization data corresponding to that state can be found based on the relationship between the process running state and the process's processor performance utilization. For example, if the target process is in the startup state, the processor performance utilization data of the target process in the startup state can be calculated.

[0098] In a feasible implementation, the step of establishing the relationship between the process running state and the process processor performance occupancy includes steps B11 to B13:

[0099] Step B11: Obtain multiple running states of the process and corresponding performance indicators;

[0100] It should be noted that process P needs to meet corresponding performance indicators in different running states to achieve smooth or non-stuttering operation. The performance indicators of each running state may include CPU occupancy, memory usage, disk I / O, network bandwidth, etc.

[0101] Table 1

[0102]

[0103]

[0104] As shown in Table 1, Table 1 is a corresponding relationship table between the running status of the process and the performance indicators.

[0105] For example, if the running state of process P is the startup state S1, the corresponding performance indicator is the startup time.

[0106] Step B12: collecting historical processor performance occupancy data when the process runs in the plurality of running states and meets the performance indicators;

[0107] It should be noted that the performance occupancy of a process when it runs in different operating states and reaches a performance indicator can be recorded, thereby obtaining multiple CPU performance occupancy data, and summarizing them to obtain historical processor performance occupancy data.

[0108] like Figure 5 As shown, Figure 5The figure below shows the CPU usage in different process states. The process states include S1, S2, and S3. The CPU usage varies in different process states.

[0109] Step B13: establishing a relationship between a process running state and a process processor performance occupancy based on the historical processor performance occupancy data and the plurality of running states.

[0110] In a specific implementation, a correspondence between the process running state and the process processor performance usage can be established based on the statistical historical processor performance usage data and the corresponding running state. For example, the processor consumption model for process P is: P = {(S1, C1), (S2, C2), (S3, C3)}.

[0111] Step S403: Control the target process according to the processor performance usage data and the currently available computing power.

[0112] It should be noted that after obtaining the current running status of the target process and the corresponding processor performance occupancy data, the performance of the target process can be adjusted and controlled in combination with the current available computing power. For example, if the current available computing power is low and the target process is a game process with high CPU usage, then its CPU usage can be reduced by limiting its CPU usage, reducing rendering quality, etc. to ensure the smooth operation of the in-vehicle display. Alternatively, if the target process is a low-priority background service process, when the current available computing power is tight, you can choose to pause or terminate the process to free up processor resources for other more important processes. Through these control strategies, the process operation on the in-vehicle display can be adjusted in real time to adapt to different work scenarios and user needs.

[0113] In a feasible implementation, step S403 may include steps C11 to C13:

[0114] Step C11: calculating the total first processor performance occupancy of the target process to be launched according to the processor performance occupancy data;

[0115] In a specific implementation, the first processor performance usage sum is the sum of the processor performance usage data of all target processes waiting to be launched in their current running states. The number and type of target processes to be launched can be determined first, and the processor performance usage of the target processes can be queried in the processor performance usage data. The processor performance usage of all target processes to be launched can be summed to obtain the first processor performance usage sum. The target processes to be launched are processes waiting to be launched, and the number of target processes to be launched can be one or more.

[0116] Step C12: Obtain application process priority;

[0117] It can be understood that the application process priority is the running order or the pull-up order of the processes, and the application process priority also reflects the importance of the corresponding process to some extent.

[0118] The application process priority can be determined based on application types, user settings, system policies, and the like. The application process priority can be obtained in advance and can also be updated according to feedback and analysis during user use. For example, the application process priority can be defined in advance and preset to the system, so that the number of currently started applications and the number of running survivors are strictly controlled in subsequent application management of the vehicle display screen.

[0119] Step C13: When the current running state is the starting state and the difference between the first processor performance occupation sum and the current available computing power is less than a preset value, the target process with a low application process priority in the target process is delayed to be pulled up.

[0120] The preset value can be set according to the performance requirements of the vehicle display screen, user experience, and the like, and is used to determine whether the current available computing power can meet the processor performance requirements of all pulled-up target processes. For example, the preset value can be set to a small value, such as 10, 15, or the like.

[0121] If the difference between the first processor performance occupation sum and the current available computing power is less than the preset value, it means that the sum of CPU occupation of all target processes in the starting state will soon exceed the current CPU actual computing power, which is easy to cause the vehicle display screen to run to be stuck. Therefore, the target process with a low application process priority in the target process can be delayed to be pulled up, and the target process with a high application process priority is pulled up first. For example, the target processes include process A, process B, and process C, the application process priority of process A Y1> the application process priority of process B Y2> the application process priority of process C Y3, if the current running state is the starting state, process A, process B, and process C should be pulled up at this time, but the first processor performance occupation sum of process A, process B, and process C will soon exceed the current available computing power. To ensure the smoothness of the vehicle, the process C with a low application process priority can be delayed to be pulled up. The delay time can be set, for example, 20s, and then process C is pulled up after 20s. The first processor performance occupation sum and the current available computing power can also be determined in real time, and if they are greater than the preset value, process C can be pulled up.

[0122] By delaying the pull-up of the process in the starting state, the running of the process on the vehicle display screen can be adjusted in real time, and the vehicle display screen can maintain the best performance in different working scenarios, and the user experience is improved.

[0123] It can be understood that the control of the target process also includes:

[0124] calculating a second processor performance occupation sum of foreground processes and background processes in the target process according to the processor performance occupation data;

[0125] when a difference between the second processor performance occupation sum and the current available computing power is less than a preset value, performing recycling processing on the background processes in the target process based on the application process priority.

[0126] It can be understood that, if the foreground processes and the background processes running in the target process are acquired at this time during the process running, the processor performance occupation of the running foreground processes and the processor performance occupation of the running background processes are inquired from the processor performance occupation data, and the second processor performance occupation sum of the running foreground processes and the background processes is added.

[0127] The difference between the second processor performance occupation sum and the current available computing power is compared with the preset value to determine whether the second processor performance occupation sum is about to exceed the current available computing power, and if the difference is less than the preset value, it indicates that the performance occupation of the currently running processes is about to exceed the current available computing power, and at this time, the processes need to be processed to improve the smoothness of the car machine.

[0128] Specifically, the background processes running in the target process can be recycled, and the background processes can be recycled by setting a recycling mechanism, and specifically, the background processes can be recycled by the application process priority, for example, the background processes include a process D, a process E and a process F, the application process priority Y4 of the process D < the application process priority Y5 of the process E < the application process priority Y6 of the process F, so the process D can be recycled first to release the processor resources and ensure that the foreground processes and the important background processes can run smoothly. It is further determined whether the second processor performance occupation sum is about to exceed the current available computing power, and if so, the process E is recycled. By recycling the background processes, the system resource allocation can be dynamically adjusted and optimized without affecting the user experience.

[0129] The embodiment acquires the current running state of the target process, determines the processor performance occupation data corresponding to the target process according to the relationship between the current running state and the process running state and the process processor performance occupation, and controls the target process according to the processor performance occupation data and the current available computing power. By considering the processor performance occupation data, it is ensured that the foreground processes and the important background processes can obtain sufficient processor resources during the running of the car display screen, and the smoothness and stability of the car display screen are ensured.

[0130] Based on the first embodiment of the present application, in the third embodiment of the present application, the same or similar contents as the above-mentioned first embodiment can be referred to the above description, and the subsequent will not be described in detail. On this basis, please refer to Figure 6 , step S10 includes steps S101-S102:

[0131] Step S101: in response to the process running request of the vehicle display screen, the application process priority and process startup time sequence are obtained according to the preset process running strategy.

[0132] In specific implementation, the preset process running strategy can be formulated based on the performance characteristics of the vehicle display screen, application type, user habits and other factors. The preset process running strategy can include application process priority and process startup time sequence, and the process startup time sequence is the order of process being pulled up.

[0133] For example, for applications that require fast response, they can be set to high priority and ensured to be pulled up as soon as possible when the vehicle display screen starts. For some non-core applications, they can be set to low priority and pulled up when the system resources are sufficient. The process startup time sequence defines the pull-up order of different applications when the vehicle display screen starts, to ensure the quick startup and running of key applications.

[0134] Step S102: according to the process startup time sequence and the application process priority, the target process corresponding to the process running request is pulled up.

[0135] By combining the application process priority and the process startup time sequence, the pull-up order and timing of the process on the vehicle display screen can be more accurately controlled, thereby optimizing the system resource allocation and improving the running efficiency and user experience of the vehicle display screen. For example, when the vehicle display screen starts, key applications such as navigation applications can be pulled up first to ensure that users can quickly obtain the required navigation information.
