Referring to fig. 1, fig. 1 is a flowchart of a power consumption control method of a vehicle-mounted terminal according to an embodiment of the present invention, and as shown in fig. 1, the power consumption control method of the vehicle-mounted terminal includes the following steps:
The above-mentioned associated information may be some information associated with the power consumption of the in-vehicle terminal generated during the driving of the vehicle, for example, external environment information in which the vehicle is located, driving state information of the vehicle, and operation state information of the in-vehicle terminal of the vehicle, and the like.

In the embodiment of the present invention, the associated information may include at least one of the external environment information, the driving state information of the vehicle, and the operating state information of the vehicle-mounted terminal, that is, the associated information may include any one or more of the above information, and may further include other associated information besides the above information, such as user feedback information, which may be flexibly changed by a developer according to a continuously improved user requirement. The obtaining of the associated information may be obtained through a corresponding approach according to the introduction of the associated information.
Optionally, the vehicle-mounted terminal has at least one input interface;
the associated information is obtained through the at least one input interface.
In an optional implementation manner, the vehicle-mounted terminal may be configured with at least one input interface, and each input interface may provide a piece of association information for the vehicle-mounted terminal, as input reference information when outputting the power consumption adjustment parameter, where when the vehicle-mounted terminal has multiple input interfaces, multiple pieces of different association information may be obtained from different input interfaces, respectively.
For example, the vehicle-mounted terminal may have three input interfaces, which are an external environment input interface, a driving state input interface, and an operation state input interface of the vehicle-mounted terminal, so that external environment information such as current weather, temperature in a vehicle, and external light intensity can be obtained through the external environment input interface, driving state information such as speed and road condition of the vehicle can be obtained through the driving state input interface, and information such as current operation content and display parameters of the vehicle-mounted terminal can be obtained through the operation state input interface of the vehicle-mounted terminal.
In this way, in this embodiment, at least one of the external environment information, the driving state information of the vehicle, and the operating state information of the vehicle-mounted terminal may be acquired through at least one input interface of the vehicle-mounted terminal, so as to obtain the associated information, so that the associated information may be acquired more quickly and easily.
Optionally, when the number of the at least one input interface is at least two, the at least one input interface includes an input interface pre-configured before the vehicle-mounted terminal leaves the factory and an input interface newly added by a developer after the vehicle-mounted terminal leaves the factory.
In order to ensure that the matched power consumption adjusting parameters are generated as comprehensively as possible according to the state of the vehicle or the vehicle-mounted terminal, before the vehicle-mounted terminal leaves a factory, a developer can configure a plurality of different input interfaces for the vehicle-mounted terminal so as to collect the related information of the vehicle or the vehicle-mounted terminal as much as possible, and can reserve at least one input interface for the vehicle-mounted terminal so that the developer redefines a new input interface according to the feedback content or new functional requirements of a user at a later stage.
That is, in this embodiment, the number of the at least one input interface is at least two, and the at least two input interfaces may include an input interface that is pre-configured before the vehicle-mounted terminal leaves the factory and an input interface that is newly added by a developer after the vehicle-mounted terminal leaves the factory.

In the embodiment of the invention, the power consumption adjusting parameter corresponding to the correlation information can be generated according to the correlation information, that is, the power consumption adjusting parameter matched with the current environment, the driving state or the running state of the vehicle-mounted terminal of the vehicle is determined based on the correlation information, and then the running parameter of the vehicle-mounted terminal is controlled according to the power consumption adjusting parameter, so that the purpose of controlling the power consumption of the vehicle-mounted terminal is achieved.
The generating of the power consumption adjustment parameter corresponding to the associated information may be to determine the power consumption adjustment parameter matching the current state of the vehicle in real time by analyzing the associated information, for example, a self-learning decision mechanism may be adopted to obtain a power consumption adjustment parameter decision model by training a plurality of sets of input data and output data, so that the corresponding power consumption adjustment parameter can be obtained by inputting the obtained associated information into the decision model. Therefore, by continuously optimizing the power consumption adjusting parameter decision mechanism, the power consumption control mode of the vehicle-mounted terminal can be continuously improved, and a power consumption adjusting and optimizing mechanism which is more in line with actual requirements is formed.
The generating of the power consumption adjusting parameter corresponding to the associated information may also be performed by configuring a plurality of different power consumption adjusting strategies in advance for different associated information, so that the corresponding power consumption adjusting parameter is decided based on the power consumption adjusting strategy corresponding to each associated information in the plurality of associated information, and finally, all the decided power consumption adjusting parameters are summarized, or the power consumption adjusting parameter in which a conflict occurs is decided again, so as to obtain the final power consumption adjusting parameter.
For example, when the associated information indicates that the vehicle-mounted terminal currently runs a music application program and the intensity of external light is strong, since the user does not need to operate the vehicle-mounted terminal at this time and does not need high display brightness, a display screen adjustment parameter for indicating to turn down the brightness of the display screen can be generated to reduce the power consumption of the vehicle-mounted terminal; when the associated information indicates that the vehicle-mounted terminal runs a plurality of application programs currently and the temperature in the vehicle is high, some unimportant application programs can be closed to avoid the high-heat phenomenon of the vehicle-mounted terminal, so that application program control parameters for indicating the closing of some application programs can be generated to reduce the power consumption of the vehicle-mounted terminal; when the associated information indicates that the current weather is rainy and the road condition is poor, and the vehicle-mounted terminal runs with the audio and video application program currently, because the user needs to concentrate on driving at the moment, a volume adjusting parameter for indicating to reduce the output volume of the vehicle-mounted terminal can be generated so as to reduce the power consumption of the vehicle-mounted terminal, and the like.
The adjusting the operation parameter of the vehicle-mounted terminal according to the power consumption adjusting parameter may be setting the power consumption adjusting parameter to the vehicle-mounted terminal to realize control of the operation state of the vehicle-mounted terminal. For example, if the power consumption adjusting parameter includes a CPU scheduling parameter, and the CPU scheduling parameter indicates that a small-core processor is allocated, the small-core processor of the vehicle-mounted terminal may be enabled to execute a current task; if the power consumption adjusting parameters comprise CPU frequency modulation parameters and the CPU frequency modulation parameters indicate that the running frequency of the CPU is limited to be not more than the preset frequency, the running frequency of the CPU of the vehicle-mounted terminal can be reduced to be not more than the preset frequency; if the power consumption adjusting parameter comprises a display screen adjusting parameter, and the display screen adjusting parameter indicates that the display brightness of the display screen of the vehicle-mounted terminal is adjusted to be preset brightness, the display brightness of the display screen of the vehicle-mounted terminal can be adjusted to be the preset brightness; if the power consumption adjustment parameter includes an application program control parameter, and the application program control parameter indicates that a certain currently running application program is closed, the application program running on the vehicle-mounted terminal may be directly closed, and so on.
In this way, compared with the prior art in which a fixed power consumption adjusting parameter is obtained according to a preset power consumption optimizing strategy, in this embodiment, by generating the power consumption adjusting parameter corresponding to the associated information, the operating parameter of the vehicle-mounted terminal can be flexibly adjusted, so as to achieve the purpose of controlling the power consumption of the vehicle-mounted terminal, and facilitate maintenance of developers.
Optionally, before step 102, the method further includes:
acquiring user behavior information, wherein the user behavior information comprises at least one of operation information, user feedback information and user usage record information aiming at the vehicle-mounted terminal;
the step 102 comprises:
and generating power consumption adjusting parameters corresponding to the associated information and the user behavior information.
In order to better combine with the actual requirements of the user to ensure that the generated power consumption adjustment parameters are more in line with the expectations of the user, user behavior information may be further acquired before the power consumption adjustment parameters corresponding to the associated information are generated, and the user behavior information may include one or more of operation information, user feedback information, user usage record information, and the like for the vehicle-mounted terminal.
The operation information for the vehicle-mounted terminal refers to operation records input by a user on the vehicle-mounted terminal, such as operation information of adjusting display brightness, adjusting volume and the like by the user; the user feedback information refers to information such as problems and opinions fed back by a user in the existing power consumption control process, such as power consumption, picture effect, screen burning and the like fed back by the user, and specifically can be information fed back by the user on a client and a webpage, or even information fed back by the user offline; the user use record information refers to user use habit information recorded by the vehicle-mounted terminal, such as user habit of using navigation in the off-duty period, habit of turning on a radio during driving, and the like.

Optionally, the associated information includes at least two items of external environment information, driving state information of the vehicle, and running state information of the vehicle-mounted terminal;
the step 102 comprises:

The tuning parameter refers to a parameter for reducing the power consumption of the vehicle-mounted terminal, which is determined according to the corresponding power consumption tuning strategy, for example, for the CPU tuning strategy, the tuning parameter may be a lower CPU operating frequency value for reducing the CPU operating frequency, for the display screen tuning strategy, the tuning parameter may be a display brightness value for dimming the display brightness, and so on.

The CPU frequency modulation and tuning strategy can limit the CPU running frequency according to the CPU load, when the tasks to be processed by the CPU are more, the higher CPU running frequency can be adopted to improve the performance of the vehicle-mounted terminal, and when the tasks to be processed by the CPU are less, the running frequency of the CPU can be reduced, and the power consumption is reduced.
The display screen tuning strategy can comprise an LCD tuning strategy or an OLED tuning strategy, wherein the LCD tuning strategy can improve the visual effect by enhancing the pixel intensity and simultaneously reduce the backlight to achieve the purpose of saving power, the OLED tuning strategy can make the white pixel show gray slightly by adjusting the value of a blue sub-pixel in RGB sub-pixels of the white pixel to achieve the purpose of reducing power consumption and solving the problem of screen burning, and the OLED tuning strategy can also reduce the brightness of the image to achieve the purpose of saving power when detecting that the average brightness of the displayed image is overhigh.
The temperature control and optimization strategy can adopt measures of limiting the running frequency of the CPU or limiting the display brightness and the like when the overhigh temperature in the vehicle is detected.
In this way, in the embodiment, the power consumption tuning strategy corresponding to each item of associated information is obtained, the tuning parameter of each power consumption tuning strategy is generated, the generated tuning parameter is processed according to a preset decision mechanism, and the power consumption adjusting parameter for the vehicle-mounted terminal is decided, so that the tuning parameters of each power consumption tuning strategy can be generated quickly and accurately, the power consumption adjusting parameter of the vehicle-mounted terminal is decided quickly, and tuning control over the power consumption of the vehicle-mounted terminal is realized.
