[0052] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0053] The menu display method for a vehicle instrument provided by an embodiment of the present application can be applied to an application environment as shown in Figure 1 The vehicle 102 is provided with various systems, such as a power system, a steering system, etc. Each system executes its respective functions through its corresponding control unit (Electronic Control Unit, ECU). In order to facilitate the cooperation of each system, a vehicle control unit (VCU) is usually provided on the vehicle 102 to manage the operation of each system.

[0054] An in-vehicle terminal 104 is also provided on the vehicle 102, also known as an in-vehicle T-BOX (Telematics Box, remote communication terminal). As a front-end device for vehicle monitoring and management, it communicates with each controller through a CAN (Controller Area Network) bus, and can obtain vehicle information such as real-time fuel consumption, engine temperature, engine speed, vehicle driving mileage, current vehicle speed, intake pressure, throttle opening, air flow, and GPS (Global Positioning System) position in real time, and receive and execute instructions sent by the vehicle controller.

[0055] The in-vehicle terminal 104 has a certain storage capacity and can locally store the operation data of the vehicle in the recent period of time, such as various data included when displaying the instrument menu.

[0056] The in-vehicle terminal 104 also has an Internet connection function and can be connected to the server 106 for communication. The in-vehicle terminal 104 and the server 106 can be directly or indirectly connected through a wired or wireless communication method, and the present application does not limit this here.

[0057] The in-vehicle terminal 104 is usually also provided with an instrument for forming a visually visible picture for human-machine interaction with the personnel inside the vehicle. The display screen of the instrument can be a liquid crystal display screen, an electronic ink display screen, or the like.

[0058] Among them, the server 106 can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, security services, and big data and artificial intelligence platforms.

[0059] In some embodiments, as Figure 2 shown, a method for displaying a menu of a vehicle instrument is provided. Taking the in-vehicle terminal in Figure 1 as an example, the method includes the following steps:

[0060] Step S202, determine the selected entry option that is currently displayed and in a selected state in the instrument menu, and determine the current text line displayed within the selected entry option.

[0061] Among them, the entry option is used to organize the content displayed in the instrument menu according to certain rules, so that the displayed content presents a certain pattern. For example, the entry option can be a long strip-shaped selection box control, so that the content presented in the instrument menu is arranged in rows of entries.

[0062] As Figure 3 shown, entry option 1 and entry option 2 are displayed in the instrument menu 302, and the two entry options are arranged in rows. Of course, the display form of the entry option can be determined according to actual needs. For example, it can also be circular or arranged in columns, etc.

[0063] In the embodiments of the present application, the entry option and the text line are separated. The entry option is edited and controlled through a selection box control, and the selection box control corresponding to the entry option covers the text line. The text line is edited and controlled through a text display control. Usually, the number of entry options is the same as the number of text lines.

[0064] In the instrument menu, the user can touch, click, or press a button, etc., among at least one entry option currently displayed, to trigger one of the entry options, and then the triggered entry option changes to a selected state, and the selected entry option is called the selected entry option. The entry option is not used for text display, and functions such as changing the color of the text can be realized through the selection box control. When the entry option is not selected, the unselected entry option can be faded, blurred, or presented with a transparent appearance effect.

[0065] It should be noted that compared with the text lines in the display state, when the display state of a text line is the invisible state, the text line can be regarded as non-existent; and each item option actually exists and occupies a certain range on the page.

[0066] Specifically, in response to a trigger operation by the user on any one of the item options displayed in the instrument menu, the vehicle-mounted terminal determines the triggered item option as the selected item option, and the selected item option is in the selected state. The vehicle-mounted terminal determines the current text line displayed within the selected item option, including: determining the text display control located at the same position as the selection box control corresponding to the selected item option; and taking the text line corresponding to the text display control as the current text line displayed within the selected item option.

[0067] Step S204, in response to a page-turning event triggered for the instrument menu, determine the target item option to be displayed after the page-turning action is performed according to the first current page to which the selected item option currently belongs; and determine the target text line to be displayed after the page-turning action is performed according to the second current page to which the current text line belongs.

[0068] Among them, the user can perform page-turning on the instrument menu. When the vehicle-mounted terminal detects a page-turning action triggered by the user, it generates a page-turning event for the instrument menu, and in response to this page-turning event, determines the target item option and the target text line that the instrument menu will display after the page-turning action is performed. The selection box control corresponding to the target item option covers the target text line.

[0069] Among them, the page-turning actions triggered by the user include but are not limited to at least one of the following: triggering an up page-turning or down page-turning, or a left page-turning or right page-turning action through a physical button or a virtual button on the instrument; performing a page-turning action by maintaining a single-point or multi-point touch on the instrument display screen and sliding up or down, or sliding left or right.

[0070] Among them, the first current page to which the selected item option currently belongs refers to which page the selected item option currently belongs to within the page range composed of multiple item options, and this page is called the first current page. In some embodiments, the first current page to which the selected item option currently belongs is related to the total number of item options set and the number of item options to be displayed on each page.

[0071] Specifically, in response to a page-turning event triggered for the instrument menu, the vehicle-mounted terminal determines the first current page to which the selected item option currently belongs, including: the vehicle-mounted terminal determines the first current page to which the selected item option currently belongs according to the total number of item options set and the number of item options to be displayed on each page.

[0072] In some embodiments, the in-vehicle terminal determines the target item option to be displayed after the paging action is to be executed according to the first current page to which the selected item option currently belongs, including: judging whether a paging action needs to be executed according to the first current page to which the selected item option currently belongs; in the case where a paging action does not need to be executed, directly determining the target item option based on the item options adjacent to the selected item option and displaying it.

[0073] Since a paging action does not need to be executed, the way of directly determining the target item option and displaying it can be to change the target item option to the selected state, while the selected item option is restored to the unselected state.

[0074] In some embodiments, in the case where a paging action needs to be executed, the in-vehicle terminal further determines the execution direction of the paging action, and determines the target item option to be displayed after the paging action is to be executed according to the execution direction of the paging action.

[0075] In some embodiments, the in-vehicle terminal responds to a paging event triggered for the instrument menu and determines the second current page to which the current text line currently belongs, including: the in-vehicle terminal determines the second current page to which the current text line currently belongs according to the total number of text lines set and the number of text lines to be displayed on each page.

[0076] In some embodiments, the in-vehicle terminal determines the target text line to be displayed after the paging action is to be executed according to the obtained second current page to which the current text line currently belongs, including: judging whether a paging action needs to be executed according to the second current page to which the current text line currently belongs; in the case where a paging action does not need to be executed, directly determining the target text line based on the text lines adjacent to the current text line and displaying it.

[0077] Since a paging action does not need to be executed, the way of directly determining the target text line and displaying it can be to change the target text line to the visible state, while the current text line is restored to the invisible state.

[0078] In some embodiments, in the case where a paging action needs to be executed, the in-vehicle terminal further determines the execution direction of the paging action, and determines the target text line to be displayed after the paging action is to be executed according to the execution direction of the paging action.

[0079] It should be noted that the above terms "first current page" and "second current page" are used to describe the page to which the selected item option currently belongs and the page to which the current text line currently belongs respectively, and the different pages are distinguished by the terms "first" and "second". However, these pages should not be restricted by these terms. These terms are only used to distinguish one page from another. For example, the first current page can be called the second current page, and similarly, the second current page can be called the first current page, without departing from the scope of the various described embodiments, but they are not the same page unless the context clearly indicates otherwise. Similar situations also include the first page range and the second page range, the first direction and the second direction, etc.

[0080] Step S206: Determine the display state of the target text line, and when the display state of the target text line is the visible state, display the target text line within the target item option after performing a page turning action.

[0081] Among them, the display state of the text line includes the visible state and the invisible state.

[0082] Since the display of the item option and the text line in this application are independent of each other, and the selection box control and the text display control are logically associated, after determining the target item option, it is equivalent to determining the display position of the text line. However, after the vehicle-mounted terminal determines the target text line, it still needs to further determine whether the target text line is finally displayed according to the display state of the target text line.

[0083] In some embodiments, the vehicle-mounted terminal determines the display state of the target text line, including: the vehicle-mounted terminal obtains the current instrument display requirement of the vehicle; among them, the instrument display requirement can be determined based on one or more of the vehicle driving state, power supply state, function usage state, or fault condition, etc.; determine the display state of the target text line according to the instrument display requirement.

[0084] When the display state of the target text line is the visible state, the vehicle-mounted terminal displays the target text line within the target item option after performing a page turning action. Specifically, the text display control corresponding to the target text line is updated to the same position as the selection box control corresponding to the target item option, and the selection box control corresponding to the target item option covers the target text line for display.

[0085] When the display state of the target text line is the invisible state, the vehicle-mounted terminal cancels the display of the target text line, and after performing a page turning action, displays the next text line of the target text line within the target item option, achieving the effect of replacement display.

[0086] In the above method for menu display of the vehicle instrument, by determining the selected item option in the currently displayed and selected state in the instrument menu, and determining the current text line displayed within the selected item option, when the user triggers a page-turning action, in response to the page-turning event triggered for the instrument menu, based on the first current page to which the selected item option currently belongs, determine the target item option to be displayed after the page-turning action is executed, and based on the second current page to which the obtained current text line currently belongs, determine the target text line to be displayed after the page-turning action is executed, separating the item options and text lines displayed in the instrument menu, and combining the display state of the target text line, and when the display state of the target text line is the visible state, display the target text line within the target item option after the page-turning action is executed. Thus, the display content can be dynamically adjusted according to the display requirements, realizing a personalized variable menu.

[0087] In some embodiments, before the vehicle-mounted terminal responds to the page-turning event triggered for the instrument menu, the above method includes: obtaining the number of item options to be displayed in each page, that is, the number of items displayed per page. The number of item options to be displayed in each page is usually preset. For example, it is preset that 3 item options are displayed in each page, etc.

[0088] Correspondingly, determining the target item option to be displayed after the page-turning action is executed based on the first current page to which the selected item option currently belongs includes: determining the first current page to which the selected item option currently belongs; determining the first page range corresponding to the selected item option according to the number of item options to be displayed in each page and the first current page; determining whether the selected item option is within the first page range, and determining the target item option to be displayed after the page-turning action is executed according to the judgment result.

[0089] Specifically, the vehicle-mounted terminal determines the first current page to which the selected item option currently belongs, and determines the first page range corresponding to the selected item option according to the number of item options to be displayed in each page and the first current page. Exemplarily, when the number of items displayed per page is N items and the first current page to which the selected item option currently belongs is the Mth page, the first page range corresponding to the selected item option is (M - 1)*N + 1 to M*N. The vehicle-mounted terminal then determines whether the selected item option is within the first page range, and determines the target item option to be displayed after the page-turning action is executed according to the judgment result. Thus, the target item option to be displayed can be quickly determined through a simple logical sequence judgment, realizing the dynamic control of the variable menu.

[0090] In some embodiments, determining whether the selected item option is within the range of the first page, and determining the target item option to be displayed after the page turning action is to be performed according to the determination result, includes: when it is determined that the selected item option exceeds the range of the first page, determining the execution direction of the page turning action; when the execution direction of the page turning action is the first direction, using the first item option located after the selected item option in the first direction as the target item option to be displayed after the page turning action is performed.

[0091] For example, taking the first direction as turning downwards as an example, when the vehicle-mounted terminal determines that the selected item option is within the range of the first page, there is no need to perform a page turning action, and directly select the next item option as the target item option; otherwise, a page turning action needs to be performed, and after performing the page turning, select the first item option as the target item option.

[0092] When the execution direction of the page turning action is the second direction, using the last item option located before the selected item option in the second direction as the target item option to be displayed after the page turning action is performed.

[0093] For example, taking the second direction as turning upwards as an example, when the vehicle-mounted terminal determines that the selected item option is within the range of the first page, there is no need to perform a page turning action, and directly select the previous item option as the target item option; otherwise, a page turning action needs to be performed, and after performing the page turning, select the last item option as the target item option.

[0094] In the above embodiments, by simply judging the logical order, the target item option to be displayed is quickly determined, realizing the dynamic control of the variable menu.

[0095] In some embodiments, before responding to the page turning event triggered for the instrument menu, the method includes: obtaining the number of text lines required to be displayed in each page, that is, the number of lines displayed per page. The number of text lines required to be displayed in each page is usually preset. For example, it is preset that each page displays 3 text lines, etc.

[0096] Correspondingly, determining the target text line to be displayed after the page turning action is to be performed according to the obtained second current page to which the current text line belongs, includes: determining the second current page to which the current text line belongs; determining the second page range corresponding to the current text line according to the number of text lines required to be displayed in each page and the second current page; judging whether the current text line is within the second page range, and determining the target text line to be displayed after the page turning action is to be performed according to the judgment result.

[0097] Specifically, the in-vehicle terminal determines the second current page to which the current text line currently belongs, and determines the second page range corresponding to the current text line according to the number of item options to be displayed in each page and the second current page. Exemplarily, when the number of items displayed per page is N and the second current page to which the current text line currently belongs is the Mth page, the second page range corresponding to the current text line is (M - 1)*N + 1 to M*N. The in-vehicle terminal then determines whether the current text line is within the second page range, and determines the target text line to be displayed after performing the page turning action according to the judgment result. Thus, the target text line to be displayed can be quickly determined through a simple logical sequence judgment, realizing the dynamic control of the variable menu.

[0098] In some embodiments, determining whether the current text line is within the second page range and determining the target text line to be displayed after performing the page turning action according to the judgment result includes: when it is determined that the current text line exceeds the second page range, determining the execution direction of the page turning action; when the execution direction of the page turning action is the first direction, using the first text line after the current text line in the first direction as the target text line to be displayed after performing the page turning action.

[0099] For example, taking the first direction as turning downwards as an example, when the in-vehicle terminal determines that the current text line is within the second page range, there is no need to perform the page turning action, and the next text line is directly selected as the target text line; otherwise, the page turning action needs to be performed, and the first text line is selected as the target text line after performing the page turning.

[0100] When the execution direction of the page turning action is the second direction, using the last text line before the current text line in the second direction as the target text line to be displayed after performing the page turning action.

[0101] For example, taking the second direction as turning upwards as an example, when the in-vehicle terminal determines that the current text line is within the second page range, there is no need to perform the page turning action, and the previous text line is directly selected as the target text line; otherwise, the page turning action needs to be performed, and the last text line is selected as the target text line after performing the page turning.

[0102] In the above embodiments, the target item option to be displayed is quickly determined through a simple logical sequence judgment, realizing the dynamic control of the variable menu.

[0103] In a specific example, the menu display method of the vehicle instrument provided according to the embodiments of the present application can be used to implement a variable menu of the instrument. Exemplarily, the in-vehicle terminal can set a checkbox control and a text display control in the application of the instrument, which are respectively used for the selection control of item options and the selection control of text lines. Among them, a logical association is made between the checkbox control and the text display control, so that the display content can be dynamically adjusted according to the display requirements to implement a variable menu. Among them, the checkbox control is used to set the total number of items and the number of items displayed per page, and the selection function of item options is implemented according to the total number of items and the number of items displayed per page. The text display control is used to determine whether a certain line of text needs to be displayed according to the display requirements, and the non-displayed line of text is filled and displayed by the next line of text.

[0104] Exemplarily, when the user triggers the instrument button, referring to Figure 4 as shown, the specific steps for the checkbox control to implement the selection function of item options include:

[0105] S1. Determine the function of the button input. If the function of the button input is to scroll up, execute S2; if the function of the button input is to scroll down, execute S3.

[0106] S2. Determine whether the selected item option is within the range of the first page. If it is, there is no need to perform a page turning operation, and directly select the previous item option; otherwise, a page turning operation is required.

[0126] Exemplarily, refer to Figure 6 As shown, the specific steps for the text display control to determine whether a certain line of text needs to be displayed according to the display requirements and use the next line of text to fill in and display the non-displayed line of text include:

[0127] S111. Determine whether to display the current line of text. Otherwise, use the next line of text to fill in and display. If so, execute S112.

[0128] S112. Display the text of the current line, determine whether the current line is the last line of the current page. If so, the display ends; otherwise, execute S113.

[0129] S113. Locate the text of the next line, determine whether the text of the next line is within the range of the second page. If not, the display ends; if so, return to execute S111.

[0130] In the embodiments of the present application, by combining two types of controls, namely a checkbox control and a text display control, a dynamically variable menu function is realized. The functional logic is similar to that of the checkbox control, but when scrolling up and down, it does not judge whether the upper / lower item checkbox selection exists, but judges whether the text line exists. The starting point of this design is that the checkbox control moves according to the text line, the checkbox control is in the same position as the text line, the item options cover the text items, and the number of item options is the same as the number of text lines. However, each item option is displayed, and the text line will determine whether the text of that line is displayed according to the property of whether the text line is displayed.

[0131] Since the item options do not display text and the unselected item options are completely transparent, what can be visually seen directly is the content of the text line below the item options. The item options are scrolled up and down for display according to the existence of the text line, so as to ensure that the selection range of the item options is within the display range of the menu text. In fact, if there are several text lines in an invisible state, the number of item options will exceed the number of text lines. However, since the item options will be displayed according to the text line, the dynamic change of the menu can be realized visually.
