Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For the convenience of understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.
Fig. 1 is a schematic flow chart of a method for adjusting a screen state according to an embodiment of the present invention, and the method includes steps of an execution process, specifically, as shown in fig. 1, the method includes:
and step 110, when a screen display control request is received, acquiring the current screen display state. Specifically, in one usage scenario, the screen states may include on-screen and off-screen.
Further, before acquiring the current screen display state, if the control on the screen state is started for the first time, the initialization processing needs to be performed according to the steps shown in fig. 2:
The state change table and the state maintenance table are used for recording display priority information among different information sources, the information sources are used for indicating the information sources needing to be displayed on a screen, the information sources include but are not limited to video information needing to be played, vehicle alarm information needing to be sent, screen feedback information triggered by clicking operation of a driver for actively awakening the screen, and the like, the display priorities corresponding to the different information sources are determined in advance according to vehicle driving safety, and if in an electric automobile, the alarm priority of insufficient power of an automobile power supply is generally higher than the display priority of entertainment videos and the like so as to prompt a user in time; similarly, in gasoline vehicles, the warning priority of gasoline shortage in the fuel tank of the vehicle is generally higher than the priority of entertainment video and other displays. The display priority between different information sources in the state change table and the state maintaining table is not limited by those skilled in the art, and those skilled in the art can determine the display priority according to actual needs.
Specifically, the screen state control tables may be one-dimensional tables, and there are two screen state control tables, namely, an on-screen state control table and an off-screen state control table. The screen state control table is used for recording the current screen state and the historical state. It should be noted that the bright screen state control table and the off screen state control table are completely the same in format and usage, and the difference is only that the objects are different, the bright screen state control table is for the bright screen state, and the off screen state control table is for the off screen state.
Furthermore, the state change table is a two-dimensional table, the two state change tables are mainly used for participating in a subsequent screen state change process, and the two state change tables are a bright screen state change table and a dead screen state change table respectively. The on-screen state change table and the off-screen state change table have the same format and usage, and are different only in the target object, the on-screen state change table is for the on-screen state, and the off-screen state change table is for the off-screen state.
Furthermore, the number of the state maintaining tables is two, the state maintaining tables are mainly used for participating in the subsequent screen state maintaining process, and the number of the state maintaining tables is two, namely a bright screen state maintaining table and a dead screen state maintaining table. It should be noted that the formats and usages of the bright screen state maintaining table and the off screen state maintaining table are completely the same, and the difference is only that the objects are different, the bright screen state maintaining table is for the bright screen state, and the off screen state maintaining table is for the off screen state.
Specifically, the state maintaining table and the state changing table are preset in advance and can be used directly, but the screen state control table is recorded through response operation or active collection, and the screen state control table needs to be initialized due to first operation, so that the information source corresponding to the initial screen state is recorded, and in a use scene, the initial information source can be recorded as NULL.
Specifically, when the first display state is the same as the second display state, the current screen may be adjusted according to the flow described in fig. 3:
In one embodiment, assume that there are three sources of information in addition to the initialized source of information, and assume that the current screen state is bright, while maintaining Table 1 assuming the following states:
TABLE 1
Where a is an abbreviation of Add, indicating that this time information should be added to the state control table. R is an abbreviation for Replace, indicating that the record of the old source in the control list is cleared and replaced with the record of the new source. N is an abbreviation of Not, which indicates that the information is Not recorded and the state control table is Not updated.
Where "N" in row 2 and column 3 of Table 1 indicates that if the old source is Source 2, the State control Table is not updated if the new source is Source 3.
Specifically, when the first display state and the second display state are consistent, although the state of the screen is not adjusted, since the information source may be changed, it may be necessary to adjust the data in the screen control table according to the state maintenance table.
In an alternative embodiment, assume the following state control table 2A exists:
TABLE 2A
| NULL | Information source 4 |
Assuming that the state maintaining table is still used as an example, and assuming that the information source corresponding to the first display state is the information source 2, the state maintaining table is looked up and corresponds to the 4 th row, the 2 nd column and "a" in the state maintaining table, and the updated state controlling table is the following table 2B:
TABLE 2B
| NULL | Information source 4 | Information source 2 |
If the information source corresponding to the first display state is information source 3, and the information source is a table look-up, the updated state control table is shown as the following table 2C, wherein the updated state control table corresponds to the state maintaining table in row 4, column 3 and R:
TABLE 2C
| NULL | Information source 3 |
If the information source corresponding to the first display state is the information source 4, and the information source is corresponding to the 4 th row and 3 rd column in the state maintaining table through table lookup, the state control table is not changed, and the table 2A is still maintained.
And step 130, when the first display state is inconsistent with the second display state, acquiring a state change table corresponding to the current screen display state, wherein the state change table records display priority information among different information sources. Specifically, the state change table is preset, stored in a designated storage area, and called directly when used.
In one embodiment, assume that there are three sources of information in addition to the initialized source of information, and assume that the current screen state is bright, while assuming the following state change table 3:
TABLE 3
Where K is an abbreviation for Keep, indicating that the original state is still maintained. C is an abbreviation of Change, indicating a screen state Change.
For example, where "N" in row 2 and column 3 of Table 3 indicates that if the old source is Source 2, the current screen state may be changed if the new source is Source 5.
Specifically, if there is only one information source corresponding to the display state of the current screen and the current screen is assumed to be a bright screen, the bright screen state control table is shown in table 4 below:
TABLE 4
| Information source 2 |
Still taking the above state change table as an example, and assuming that the information source corresponding to the first display state is the information source 5, the table is looked up and corresponds to the 2 nd row and column 2 in the state change table, which is "C", indicating that the change is possible, and since the screen state is bright at this time, the screen state is to be adjusted to be off.
Furthermore, when the display state of the screen changes, the screen state control list corresponding to the next display state is updated, and the screen state control list records the corresponding information source.
Still taking the above embodiment as an example, it is necessary to record the new information source in the off-screen state maintaining table, which is shown in the following table 5:
TABLE 5
| Information source 4 |
Furthermore, if a plurality of information sources corresponding to the current screen display state exist, each information source is compared with the information source contained in the screen display control request to determine the next screen display state.
Assuming that the current screen is bright, the bright state control table is shown in table 6 below:
TABLE 6
| Information source 2 | Information source 3 |
Still taking the above state change table as an example, and assuming that the information source corresponding to the first display state is the information source 5, through table lookup, for the information source 2, the 2 nd row and 2 nd column in the correspondence table is "C", it indicates that the change is possible, for the information source 3, the 3 rd row and 2 nd column in the correspondence table is "K", it indicates that the change is not possible, in the case that there are a plurality of information sources, as long as there is one information source indicating that the current screen state is not changeable, the entire screen state is not changed, in the case as shown in table 6, the screen state is not changed, and the bright screen state is still maintained.
The invention provides a screen state adjusting method, which comprises the steps of obtaining a current screen display state when a screen display control request is received, determining whether a first display state corresponding to screen display state adjusting information contained in the screen display control request is consistent with a second display state corresponding to the current screen display state, obtaining a state change table corresponding to the current screen display state when the first display state is inconsistent with the second display state, recording display priority information among different information sources in the state change table, and determining the next display state of a screen according to the state change table corresponding to the current screen display state, the information sources corresponding to the current screen display state and the information sources contained in the screen display control request. By comparing the priorities of different information sources, the screen can respond to the control request sent by the information source with high priority at any time, so that the on and off of the screen can be flexibly controlled under different conditions, and the driving safety of the vehicle is ensured.
