Detailed Description of Embodiments



[0017] The onboard terminal device, the display control method, the display control apparatus and the computer device according to the invention will be further described below in detail in conjunction with the accompanying drawings. It should be noted that the following detailed description of embodiments is exemplary rather than limiting, and is intended to provide a basic understanding of the invention, but not to confirm key or decisive elements of the invention or limit the scope of protection.

[0018] The invention is described below with reference to block diagram illustrations, block diagrams and/or flowcharts of the method and apparatus in the embodiments of the invention. It should be understood that each block of the flowchart illustrations and/or the block diagrams and combinations of the flowchart illustrations and/or the block diagrams may be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general-purpose computer, a special-purpose computer or other programmable data processing devices to form a machine, such that the instructions, which are executed by the processor of the computer or the other programmable data processing devices, create components for implementing functions/operations specified in the flowcharts and/or blocks and/or one or more flow block diagrams.

[0019] These computer program instructions may be stored in a computer-readable memory and may instruct a computer or other programmable processors to implement functions in a specific manner, so that these instructions stored in the computer-readable memory constitute an article of manufacture, which contains instruction components for implementing the functions/operations specified in one or more blocks of the flowcharts and/or block diagrams.

[0020] These computer program instructions may be loaded onto a computer or other programmable data processors to enable a series of operational steps to be executed on the computer or the other programmable processors, so as to constitute a computer-implemented process, so that these instructions executed on the computer or the other programmable data processors provide steps for implementing the functions or operations specified in one or more blocks of the flowcharts and/or block diagrams. It should also be noted that in some alternative implementations, the functions/operations shown in the blocks may occur in an order different from that shown in the flowchart. For example, two blocks shown in sequence may actually be executed substantially simultaneously or may sometimes be executed in a reverse order, which depends on the functions/operations involved.

[0021] An example block diagram of an onboard terminal device according to one implementation of the invention will be described below in conjunction with Fig. 1.

[0022] Fig. 1 is an example block diagram of an onboard terminal device according to one implementation of the invention. The onboard terminal device 100 may be mounted on a vehicle (such as an electric vehicle or other types of vehicles). For example, it may be specifically an onboard console apparatus provided with a display 101 similar to a console screen and a controller 102 similar to an ECU, wherein the display 101 may provide various user interfaces (UIs) and one or more interactive elements (not shown) on the user interfaces (UIs) that are configured to implement various functions, and the controller 102 can control various operations including a display operation.

[0023] In one embodiment, the onboard terminal device 100 may further comprise one or more input sensors configured to provide the controller 102 with a user input or user instruction. The controller 102 may analyze the user input or user instruction to identify an interactive element of a user interface affected by the user input or user instruction and perform a function associated with the identified interactive element. For example, the controller 102 may identify an operated interactive element and cause the display 101 to display an associated display interface in response to the user input or user instruction.

[0024] Specifically, the one or more input sensors may be, for example, touch sensors, which may be arranged on the display 101 or arranged integrally with the display 101. In one example, the one or more input sensors may detect a direct contact of a user's finger or the like. Based on the position of the contact on the user interface (UI), the controller 102 may identify a corresponding interactive element related to the current position of the contact, and may open a display interface associated with the interactive element.

[0025] The one or more input sensors may also be, for example, acoustic input sensors, such as microphones, which may detect a speech command indicated by a required interactive element. For example, the user may identify the required interactive element with a tag or any other suitable identifier, and may also describe a required action to be performed that is related to the required interactive element. The controller 102 may identify the speech command, and submit, to the user interface or its processing component or engine, data for characterizing an interaction.

[0026] Although the onboard terminal device 100 has been described as comprising several components, including the display 101 and the controller 102, and one or more input sensors, it should be understood that the onboard terminal device 100 may further comprise other output devices of the same or other modes, such as a speaker or a vibrotactile feedback layer, or may comprise other input sensors, such as a keyboard, a camera, a depth sensor, an interface that can be connected to an external input device, etc.

[0027] In conjunction with Figs. 1 and 2, the display 101 may be configured to provide a plurality of display interfaces. The plurality of display interfaces include, but are not limited to, a desktop Launcher display interface, an application (APP) display interface, a Button display interface, a heating ventilation air conditioning (HVAC) display interface, an application list (APP List) display interface, a shortcut menu (Shortcut) display interface, an after-sales service (NIO Service) display interface, etc. shown in Fig. 2.

[0028] In conjunction with Figs. 1 and 2, the controller 102 may be configured to compare, in response to an instruction for newly adding a display interface from the plurality of display interfaces for displaying, a hierarchical attribute of a predetermined current display interface with a hierarchical attribute of the display interface to be newly added, and perform, based on the result of the comparison, a corresponding operation on the current display interface and the display interface to be newly added. For example, in one embodiment, the controller 102 may be further configured to control, where the hierarchical attribute of the current display interface is different from the hierarchical attribute of the display interface to be newly added, or where the hierarchical attribute of the current display interface and the hierarchical attribute of the display interface to be newly added are the same and are both hierarchical superimposition attributes, the display 101 to perform displaying in such a way that the display interface to be newly added is superimposed on the current display interface. In addition, in another embodiment, the controller 102 may be further configured to control, where the hierarchical attribute of the current display interface and the hierarchical attribute of the display interface to be newly added are the same and are both hierarchical mutual exclusion attributes, the display 101 to perform displaying in such a way that the current display interface is replaced with the display interface to be newly added by closing the current display interface.

[0029] The operating of the display 101 and the controller 102 in Fig. 1 will be described below in detail using Fig. 2 as an example. Fig. 2 is a schematic diagram of hierarchies in a display interface according to one embodiment of the invention. In the example of Fig. 2, the display 101 may provide a plurality of display interfaces, including various display interfaces shown in Fig. 2. It is assumed that hierarchical attributes of these display interfaces are predetermined as follows: the HVAC display interface, the APP List display interface, the Shortcut display interface, and the NIO Service display interface are all of hierarchical mutual exclusion attributes, while other display interfaces are of hierarchical superimposition attributes. With regard to the operating of the display 101 and the controller 102 according to one implementation of the invention, for example, where the current display interface is the APP display interface, when a user performs an interactive operation on an interactive element related to a button to open the Button display interface, the controller 102 compares, in response to the user's instruction, a hierarchical attribute of the currently displayed APP display interface with a hierarchical attribute of the Button display interface to be newly added; and because the hierarchical attributes of the two display interfaces are both hierarchical superimposition attributes, the controller 102 controls the display 101 to perform displaying in such a way that the Button display interface is superimposed on the currently displayed APP display interface. Moreover, for example, when the current display interface is changed to the Button display interface due to the above process, the user performs an interactive operation on an interactive element related to an air conditioner to open the HVAC display interface, and in response to this, the controller 102 compares a hierarchical attribute of the currently displayed Button display interface with a hierarchical attribute of the HVAC display interface to be newly added; and because the two display interfaces are different from each other in terms of the hierarchical attribute (that is, the former is of the hierarchical superimposition attribute and the latter is of the hierarchical mutual exclusion attribute), the controller 102 controls the display 101 to perform displaying in such a way that the HVAC display interface is superimposed on the currently displayed Button display interface. Moreover, for example, when the current display interface is changed to the HVAC display interface due to the above process, the user performs an interactive operation on an interactive element related to a shortcut menu to open the Shortcut display interface, and in response to this, the controller 102 compares a hierarchical attribute of the currently displayed HVAC display interface with a hierarchical attribute of the Shortcut display interface to be newly added; and because the hierarchical attributes of the two display interfaces are both hierarchical mutual exclusion attributes, the controller 102 controls the display 101 to perform displaying in such a way that the currently displayed HVAC display interface is replaced with the Shortcut display interface to be newly added by closing the currently displayed HVAC display interface.

[0030] A display control method for an onboard terminal device according to one implementation of the invention will be described below in conjunction with Fig. 3.

[0031] As shown in Fig. 3, the display control method S100 comprises a display step (S1), in which the display 101 provides a plurality of display interfaces.

[0032] Moreover, as shown in Fig. 3, the display control method S100 comprises an attribute comparison step (S2), in which the controller 102 compares, in response to an instruction for newly adding a display interface from the plurality of display interfaces for displaying, a hierarchical attribute of a predetermined current display interface with a hierarchical attribute of the display interface to be newly added.

[0033] Moreover, as shown in Fig. 3, the display control method S100 comprises a display control step (S3), in which the controller 102 performs, based on the result of the comparison in S2, a corresponding operation on the current display interface and the display interface to be newly added. For example, in one embodiment, in the display control step, where the hierarchical attribute of the current display interface is different from the hierarchical attribute of the display interface to be newly added, or where the hierarchical attribute of the current display interface and the hierarchical attribute of the display interface to be newly added are the same and are both hierarchical superimposition attributes, the controller 102 controls the display 101 to perform displaying in such a way that the display interface to be newly added is superimposed on the current display interface. In addition, in another embodiment, in the display control step, where the hierarchical attribute of the current display interface and the hierarchical attribute of the display interface to be newly added are the same and are both hierarchical mutual exclusion attributes, the controller 102 controls the display 101 to perform displaying in such a way that the current display interface is replaced with the display interface to be newly added by closing the current display interface.

[0034] A schematic diagram of modules in a display control apparatus (i.e., an onboard terminal device) according to one implementation of the invention will be described below in conjunction with Fig. 4. As shown in Fig. 4, the display control apparatus (i.e., the onboard terminal device) 200 comprises a display module 201 configured to provide a plurality of display interfaces. The plurality of display interfaces include, but are not limited to, a desktop Launcher display interface, an application (APP) display interface, a Button display interface, a heating ventilation air conditioning (HVAC) display interface, an application list (APP List) display interface, a shortcut menu (Shortcut) display interface, an after-sales service (NIO Service) display interface, etc. shown in Fig. 2.

[0035] Moreover, as shown in Fig. 4, the display control apparatus (i.e., the onboard terminal device) 200 further comprises an attribute comparison module 202 configured to compare, in response to an instruction for newly adding a display interface from the plurality of display interfaces for displaying, a hierarchical attribute of a predetermined current display interface with a hierarchical attribute of the display interface to be newly added.

[0036] Moreover, as shown in Fig. 4, the display control apparatus (i.e., the onboard terminal device) 200 further comprises a display control module 203 configured to perform, based on the result of the comparison in the attribute comparison module 202, a corresponding operation on the current display interface and the display interface to be newly added. For example, in one embodiment, the display control module 203 controls, where the hierarchical attribute of the current display interface is different from the hierarchical attribute of the display interface to be newly added, or where the hierarchical attribute of the current display interface and the hierarchical attribute of the display interface to be newly added are the same and are both hierarchical superimposition attributes, the display module 201 to perform displaying in such a way that the display interface to be newly added is superimposed on the current display interface. In addition, in another embodiment, the display control module controls, where the hierarchical attribute of the current display interface and the hierarchical attribute of the display interface to be newly added are the same and are both hierarchical mutual exclusion attributes, the display module 201 to perform displaying in such a way that the current display interface is replaced with the display interface to be newly added by closing the current display interface.

[0038] Fig. 5 shows a computer device according to one implementation of the invention that is configured to perform a display control method according to one implementation of the invention. As shown in Fig. 5, the computer device 300 comprises a memory 301 and a processor 302. Although not shown, the computer device 300 further comprises a computer program that is stored on the memory 301 and executable on the processor 302. The program implements, when executed by the processor 302, various steps, for example as shown in Fig. 3, of the display control method according to one implementation of the invention.

[0039] In addition, as described above, the invention may also be implemented as a recording medium, which stores a program for enabling a computer to perform a display control method according to one implementation of the invention.

[0040] Here, various types of recording media, such as disks (e.g., a magnetic disk, an optical disk, etc.), cards (e.g., a memory card, an optical card, etc.), semiconductor memories (e.g., a ROM, a non-volatile memory, etc.), and tapes (e.g., a magnetic tape, a cassette tape, etc.), can be used as the recording medium.

[0041] By recording, in these recording media, a computer program that enables a computer to perform the display control method in the implementations above or a computer program that enables a computer to implement functions of the display control apparatus in the implementations above and circulating the computer program, costs are reduced, and portability and versatility are improved.

[0042] Furthermore, the recording medium is loaded on a computer, the computer reads the computer program recorded in the recording medium and stores same in a memory, and a processor (central processing unit (CPU) and a micro processing unit (MPU)) provided on the computer reads out and executes the computer program from the memory, whereby the display control method in the implementations above can be performed, and functions of the display control apparatus in the implementations above can be implemented.

[0043] Those of ordinary skill in the art should understand that the invention is not limited to the implementations above, and the invention can be implemented in many other forms without departing from the essence and scope thereof. Therefore, the presented examples and implementations are regarded to be schematic rather than restrictive, and without departing from the spirit and scope of the invention that are defined by the appended claims, the invention may cover various changes and replacements.
