Description

Technical Field

[0001] The present disclosure relates to the field of intelligent driving, and more specifically, to a method and system for evolving an in-vehicle digital assistant across the entire life cycle of a vehicle. Background Art

[0002] Currently, with the increasing demand for in-vehicle interconnection solutions, the application of in-vehicle digital assistants is becoming more and more common. For example, in-vehicle digital assistants allow drivers to obtain information and perform tasks while driving (for example, making calls, navigation, sending messages or playing music, or more personalized situational services, etc.).

[0003] However, current in-vehicle digital assistants do not have a virtual image (e.g., only a voice assistant) or only have a fixed virtual image, and the knowledge they possess (e.g., the functions they can implement) is updated through version iterations, which cannot reflect the evolutionary process across the entire life cycle of the vehicle.

[0004] Therefore, in order to further improve the interactivity between the in-vehicle digital assistant and the user, it is desired to provide an improved in-vehicle digital assistant evolution solution, which enables the in-vehicle digital assistant to evolve or grow (for example, change the virtual image or expand professional knowledge) at various stages of the entire life cycle of the vehicle (including, for example, pre-purchase consideration, function upgrades, vehicle replacement, etc.), thereby further enhancing the user's driving experience.

[0032] The present disclosure is described in detail below in conjunction with the accompanying drawings, and the features of the present disclosure will be further revealed in the following specific description. The term "vehicle" used throughout the specification refers to any type of automobile, including but not limited to cars, vans, trucks, buses, etc.

[0033] Figure 1 FIG. 1 shows a schematic architecture diagram of an in-vehicle digital assistant evolution system 100 according to an embodiment of the present disclosure. Figure 1As shown, the system 100 may include at least a virtual image creation device 102, a professional field adding device 104 and a digital assistant evolution device 106.

[0034] The virtual image creation device 102 can create or initialize the initial virtual image of the in-vehicle digital assistant.

[0035] In one embodiment, the initial virtual image of the in-vehicle digital assistant can be customized or generated based on the analysis of user behavior.

[0036] In one embodiment, the initial avatar of the in-vehicle digital assistant may be displayed in a non-materialized form (e.g., an incubator or an egg), as further described below. Figure 2 As described in.

[0037] The professional field adding device 104 can add an initial professional field to the in-vehicle digital assistant when creating the in-vehicle digital assistant. The professional field can indicate the functions that the in-vehicle digital assistant can implement or the services that it can provide.

[0038] like Figure 2 As shown, Figure 2 An example flow chart 200 for creating an in-vehicle digital assistant according to an embodiment of the present disclosure is shown. In step 202, the user's identity tag and purchase intention and preference can be determined based on an analysis of user behavior or a questionnaire.

[0039] In one embodiment, the analysis of user behavior is achieved by acquiring user platform data connected to third-party vehicle-related applications, services, or media channels and analyzing the acquired data.

[0040] In one example, the user's identity tag (e.g., environmentalist) and purchase intention and preference (e.g., preference for new energy vehicles) can be determined by obtaining platform data such as web page searches, public account following, blog following, etc., and analyzing these data. The above analysis can be achieved, for example, by methods such as machine learning or deep learning. Of course, various other methods known to those skilled in the art can also be used to achieve the above analysis.

[0041] In step 204 , a corresponding initial virtual image of the in-vehicle digital assistant may be created based on the determined identity tag and purchasing intention and preference of the user.

[0042] For example, different initial virtual images of the in-vehicle digital assistant can be created based on different identity tags and vehicle model preferences of the users, for example, in the form of incubators with different patterns. Thus, the initial virtual image of the in-vehicle digital assistant can be customized according to different users and be more personalized.

[0043] In addition, when creating an in-vehicle digital assistant, an initial professional field E1 (ie, the services that can be provided) can be added to the in-vehicle digital assistant.

[0044] In one example, the initial virtual image of the in-vehicle digital assistant is a non-figurative image created during the car purchase consideration stage, and the initial professional field added is the digital business field, which may include services provided before car purchase, such as one or more of selling car models, experience activities or auto finance (loans, installments, etc.).

[0045] return Figure 1 The digital assistant evolution device 106 can then evolve the in-vehicle digital assistant based on the transitions of various stages in the vehicle's life cycle. The above evolution may include changing or updating the virtual image of the in-vehicle digital assistant or expanding the professional field of the in-vehicle digital assistant.

[0046] In one embodiment, after the vehicle is purchased, the digital assistant evolution device 106 may evolve the virtual image of the in-vehicle digital assistant into a more concrete image based on the model of the selected vehicle, and add professional fields associated with the model and optional functions of the selected vehicle to the in-vehicle digital assistant.

[0047] In one embodiment, the above-mentioned professional fields may include one or more of the smart cockpit field (for example, connected services (such as playing music, etc.), OTA upgrades, multimodal interaction, etc.), autonomous driving field (for example, L2+, L3, L4, etc.), and energy service field (such as charging and swapping services, battery recycling, etc.).

[0048] In one embodiment, the digital assistant evolution device 106 can change the virtual image of the in-vehicle digital assistant and expand the corresponding professional field based on the current interaction with the smart cockpit during driving, as further described below. Figure 3 as shown in .

[0049] In one embodiment, the digital evolution device 106 can change the virtual image of the in-vehicle digital assistant and expand the corresponding professional field based on the upgraded functions when the vehicle is upgraded, as further described below. Figure 4 as shown in .

[0050] In one embodiment, the digital evolution device 106 can change the virtual image of the in-vehicle digital assistant and expand the corresponding professional field based on the replaced vehicle when the vehicle is replaced, as further described below. Figure 5 as shown in .

[0051] In one embodiment, the digital evolution device 106 may change or update the virtual image of the in-vehicle digital assistant based on the analysis of the user's driving behavior.

[0052] For example, when the analysis results of the user's driving behavior indicate that the user prefers green driving (for example, driving a new energy vehicle, paying ETC fees, or saving fuel through reasonable driving behavior, etc.), the virtual image of the in-vehicle digital assistant can be updated accordingly (for example, adding a green helmet, etc.).

[0053] In one embodiment, the visual display of the in-vehicle digital assistant includes a personalized theme. For example, the personalized theme can be changed based on the user's driving behavior. For example, when the user travels green, the personalized theme background can be updated accordingly (for example, a theme background showing a better environment).

[0054] Those skilled in the art will appreciate that the system 100 and its modules disclosed herein can be implemented in hardware or software, and the modules can be combined or combined in any suitable manner. The system 100 can be integrated into a vehicle system, or can be integrated into a personal computer, a tablet, a smart phone, etc.

[0055] The following Figure 3-5 Different scenarios for the evolution of in-vehicle digital assistants are shown in the figure.

[0056] Figure 3 FIG. 1 is a schematic diagram showing a first scenario of the evolution of an in-vehicle digital assistant according to an embodiment of the present disclosure. Figure 3 As shown, before the vehicle is purchased, the initial virtual image of the in-vehicle digital assistant can be created based on the user's identity tag, etc., in the form of an incubator or egg. Further, the corresponding initial professional field, namely the digital business field E1, can be added to the in-vehicle digital assistant, which can include one or more of sales model display, product experience activities or automobile finance.

[0057] Subsequently, after the vehicle purchase is completed, the virtual image of the in-vehicle digital assistant can be evolved into a more concrete image based on the selected vehicle model, and correspondingly, professional fields associated with the selected vehicle model and optional functions are added to the in-vehicle digital assistant, here being the smart cockpit field E2.

[0058] The avatar of the in-vehicle digital assistant can then be improved during driving based on the current interaction with the smart cockpit. Figure 3 In the scenario, since music is currently playing, a pair of headphones can be added to the current virtual image of the in-vehicle digital assistant, and music-related services (such as play, pause, switch, etc.) can be provided accordingly.

[0059] Figure 4 FIG. 1 is a schematic diagram showing a second scenario of the evolution of an in-vehicle digital assistant according to an embodiment of the present disclosure. Figure 4 As shown, Figure 3Similar to the evolutionary process in, before purchasing a vehicle, an initial virtual image of the in-vehicle digital assistant can be created based on the user's identity tag, and the corresponding digital business field E1 can be added. Then, after the vehicle purchase is completed, the virtual image of the in-vehicle digital assistant can be evolved into a more concrete image based on the model of the selected vehicle, and the associated smart cockpit field E2 can be added to the in-vehicle digital assistant accordingly.

[0060] Later, when the vehicle is upgraded, the virtual image of the in-vehicle digital assistant can be changed based on the upgraded functions and the corresponding professional fields can be expanded. Figure 4 In the scenario, since the vehicle has upgraded its night vision function, a pair of X-ray glasses can be added to the current virtual image of the in-vehicle digital assistant based on this function and the corresponding autonomous driving field E3 (which can, for example, provide autonomous driving related services) can be added.

[0061] Figure 5 FIG. 1 is a schematic diagram showing a second scenario of the evolution of an in-vehicle digital assistant according to an embodiment of the present disclosure. Figure 5 As shown, Figure 3 and 4 Similar to the evolutionary process in, before purchasing a vehicle, an initial virtual image of the in-vehicle digital assistant can be created based on the user's identity tag, and the corresponding digital business field E1 can be added. Then, after the vehicle purchase is completed, the virtual image of the in-vehicle digital assistant can be evolved into a more concrete image based on the model of the selected vehicle, and the associated smart cockpit field E2 can be added to the in-vehicle digital assistant accordingly.

[0062] Subsequently, when a vehicle is replaced, the virtual image of the in-vehicle digital assistant can be changed based on the replaced vehicle and the corresponding professional field can be expanded. Figure 5 In the scenario, since the replaced vehicle is a new energy vehicle and is equipped with an autonomous driving function, a green helmet can be added to the current virtual image of the on-board digital assistant, and the corresponding autonomous driving field E3 and energy service field E4 (which, for example, provides charging and battery replacement services, etc.) can be added.

[0063] Of course, it is understandable that the virtual image of the in-vehicle digital assistant can also be evolved and the professional field can be expanded accordingly based on the transitions in various other stages of the vehicle's life cycle.

[0064] As can be seen from the above scenarios, a more efficient and interactive driving experience can be created by evolving the virtual image and professional domain knowledge of the in-vehicle digital assistant across the entire life cycle of the car (including, for example, pre-purchase considerations, feature upgrades, vehicle replacements, etc.).

[0065] Figure 6An example flow chart of an in-vehicle digital assistant evolution method 600 according to one embodiment of the present disclosure is shown.

[0066] The method 600 begins at step 602 , where the avatar creation device 102 may create an initial avatar of the in-vehicle digital assistant.

[0067] In one embodiment, the user's identity tag, purchase intention, vehicle model preference, etc. can be determined based on an analysis of user behavior or a questionnaire survey, and the corresponding initial virtual image of the in-vehicle digital assistant can be created based on the determined user's identity tag, purchase intention and preference.

[0068] In one embodiment, the analysis of user behavior may be achieved by acquiring user platform data connected to a third-party application, service, or media channel and analyzing the acquired data.

[0069] In step 604 , the professional field adding device 104 may add an initial professional field to the in-vehicle digital assistant, where the professional field indicates the functions that the in-vehicle digital assistant can implement or the services that it can provide.

[0070] In one embodiment, the above-mentioned initial virtual image can be a non-figurative image created during the car purchase consideration stage (for example, in the form of an incubator), and the corresponding initial professional field includes the digital business field, which may include one or more of selling car models, experience activities or auto finance.

[0071] In step 606, the digital assistant evolution device 106 may evolve the in-vehicle digital assistant based on the transitions of various stages in the vehicle's life cycle, and the evolution includes changing the virtual image of the in-vehicle digital assistant or expanding at least one of the professional fields of the in-vehicle digital assistant.

[0072] In one embodiment, the digital assistant evolution device 106 can evolve the virtual image of the in-vehicle digital assistant into a more concrete image (e.g., a human form) based on the model of the selected vehicle after the vehicle purchase is completed, and can add professional fields associated with the model and optional functions of the selected vehicle to the in-vehicle digital assistant.

[0073] In one example, the above-mentioned professional fields include one or more of the smart cockpit field, the autonomous driving field, and the energy service field.

[0074] For example, when the selected vehicle is a new energy vehicle and is equipped with an optional autonomous driving (AD) function, related professional fields (such as smart cockpit field, autonomous driving field, and energy service field) can be added to the in-vehicle digital assistant accordingly.

[0075] In one embodiment, the digital assistant evolution device 106 can change the virtual image of the in-vehicle digital assistant and expand the corresponding professional field based on the current interaction with the smart cockpit during driving.

[0076] In one embodiment, the digital assistant evolution device 106 can change the virtual image of the in-vehicle digital assistant and expand the corresponding professional field based on the upgraded functions when upgrading the vehicle.

[0077] In one embodiment, the digital assistant evolution device 106 can change the virtual image of the in-vehicle digital assistant and expand the corresponding professional field based on the replaced vehicle when the vehicle is replaced.

[0078] In one embodiment, the digital assistant evolution device 106 can change the virtual image of the in-vehicle digital assistant based on the analysis of the user's driving behavior.

[0079] In one embodiment, the visual display of the in-vehicle digital assistant may include a personalized theme. The personalized theme may change based on the user's driving behavior.

[0080] Therefore, compared to the existing fixed digital assistant virtual image, the present application improves the user driving experience and enhances the interactivity between the user and the digital assistant by evolving the virtual image and professional domain knowledge of the in-vehicle digital assistant across the entire life cycle of the car (including, for example, pre-purchase considerations, function upgrades, vehicle replacements, etc.).

[0081] Figure 7 Schematic diagram of the in-vehicle digital assistant evolution system 700 according to one embodiment of the present disclosure is shown.
