As shown in fig. 1, an embodiment of the present invention provides a vehicle parameter generation method, including:
And step 12, generating a scene use case list according to the plurality of scene elements, wherein the scene use case list comprises a plurality of scene use cases.
And step 13, establishing a corresponding relation between the scene use cases in the scene use case list and the vehicle functions.
And 14, generating vehicle parameters of the target demand function according to the corresponding relation.
According to the embodiment of the invention, the scene elements are extracted from the historical use parameters of the vehicle to obtain the scene use case, all factors in the use or design of the vehicle can be considered more comprehensively, the function development of the vehicle is guided more clearly, and meanwhile, the vehicle which is subjected to function design from the scene can more comprehensively meet the actual requirements of users in the use of various functions, so that the user experience is improved.
The vehicle usage data refers to the most basic data information about the vehicle collected from three dimensions of people, vehicles and environment, wherein the vehicle usage data may be data in the aspects of roles, identities, features, usage intentions and the like from the perspective of users; from the vehicle angle, the vehicle usage data may be data on vehicle status, direction of travel, trend of travel, status of components, etc.; from an environmental perspective, the vehicle usage data may be data in terms of season, weather, road environment, traffic signs, and the like.
Specifically, the step 11 extracts a plurality of scene elements from the vehicle historical usage data, including:
acquiring target attributes of scene elements to be extracted; dividing the vehicle historical usage data into a plurality of dimensions of data; and extracting data corresponding to the target attribute from the vehicle historical use data of each dimension to obtain the scene element required to be extracted.
It should be noted that, when extracting the scene element from the vehicle historical usage data, in order to improve the extraction efficiency, the vehicle historical usage data is classified and divided into multiple dimensions for hierarchical management, a target attribute of the scene element to be extracted is determined first, then data corresponding to the target attribute is selected from each dimension of the vehicle historical usage data according to the target attribute, and finally the scene element to be extracted is obtained.
As shown in fig. 2, the scene elements may preferably be managed hierarchically according to a full lifecycle of the vehicle, wherein the lifecycle of the vehicle comprises: the method comprises five stages of production, transportation, 4S shop, delivery of customers and scrapping, wherein the current state of the vehicle can be further obtained by further dividing for each stage, for example, the production stage comprises a production line, repair and quality inspection, the 4S shop stage comprises stock vehicles, display vehicles and test driving vehicles, and the scrapping stage comprises a scrapping mode, battery recycling and vehicle scrapping. In particular, various user behaviors are analyzed in the stage of delivering the user, and the analysis comprises the analysis of unused vehicles, the analysis of needing to use the vehicles, the analysis of using the vehicles, the analysis of completing the vehicles and the analysis of service requirements of manufacturers from the aspect of user requirements; the analysis in terms of vehicle demand includes: charging/refueling, maintenance and fault handling; the analysis from the aspect of manufacturer requirements comprises: monitoring vehicle state, collecting user opinions and solving user appeal. Further, the states of the vehicles classified in the scene library include standing, vehicle searching, charging and the like. It should be noted that, when the scene elements are managed hierarchically according to the vehicle life cycle, the basic principle followed by the classification of the primary and secondary scenes is as follows: the method comprises the following steps that a user uses a vehicle time axis principle, a user uses a vehicle space position change principle, a user uses a road type principle when the user uses a vehicle to drive, and a user behavior principle.
Specifically, when the operation in step 11 is performed, it is necessary to determine a target attribute of the scene element to be extracted, and then extract data corresponding to the target attribute in each dimension, so as to acquire a plurality of scene elements to be extracted. For example, the target attribute is charging, and it is necessary to traverse scene elements in all dimensions, preferably, a next-level sub-dimension may also be set in a dimension, so that the screening process is more accurate, thereby extracting a scene element strongly related to the target attribute of charging in each dimension, and finally, the obtained plurality of scene elements are arranged and combined to obtain a corresponding scene use case.
Further, in order to standardize the management of the scenario use cases, the embodiment of the present invention further includes step 12 of generating a scenario use case list according to the plurality of scenario elements, where the scenario use case list includes a plurality of scenario use cases.
It should be noted that, according to the extracted multiple scene elements, a scene use case may be obtained, a specific scene corresponding to the scene use case is analyzed to obtain a possible requirement of the user, a detailed description document of the scene use case is completed through the ULM language modeling, and the detailed description document is provided to the designer, so that the conversion from the scene use case to the target requirement function is completed. The embodiment of the invention also comprises the step of establishing the corresponding relation between the scene use cases in the scene use case list and the vehicle functions.
It should be further noted that the scene elements are the most important and basic elements constituting the scene use case, and are extracted according to various aspects involved in the closed system of the human-vehicle-environment, and are subjected to dimension division according to the characteristics of the scene elements, so that each scene element is given a specific attribute. Specifically, the attributes of the scene element include a belonging category, a domain, a related element, an influence range, and the like. For example, the category attribute includes person, car, environment, etc.; the domain attributes include safety, comfort, user experience, component life, and the like. By managing the scene elements in a dimensionality mode, later deletion, addition and updating can be facilitated, and attributes can be continuously optimized and updated. In addition, the scene use case list is generated based on the scene elements, so the scene use cases in the scene use case list can be classified according to the attributes of the scene elements forming the scene use cases, and further, when the obtained scene use cases are added to the scene use case list, the obtained scene use cases can be associated with the corresponding attributes. Therefore, in step 12, generating a scene use case list according to the plurality of scene elements includes: arranging and combining a plurality of scene elements to obtain a scene use case; associating the scene use case into a scene use case list according to scene element attributes, wherein the scene element attributes comprise: category, domain, related elements and scope of influence.

judging whether a scene case associated with the existing vehicle function exists in the scene case list; if so, establishing a corresponding relation between the existing vehicle function and the scene case; if the vehicle function does not exist, analyzing the existing vehicle function to obtain a scene use case, and adding the scene use case into the scene use case list.
It should be noted that, according to the existing function, it is checked whether the scene use case list generated by the scene element completely covers the existing function list, if not, the existing function, that is, the scene use case to which the omitted function belongs, is analyzed, and if the scene use case is in the scene use case list, the corresponding relationship between the scene use case and the existing function is established; if the scene case is not in the scene case list, the scene case is added into the scene case list, and meanwhile, the corresponding relation between the scene case and the existing function is established, so that the purpose of perfecting the scene case list is achieved.
As shown in fig. 3, the improvement of the scene use case list includes a forward mode and a reverse mode, the forward mode is mainly the forward mode, the reverse mode is the auxiliary mode, and the integrity of the scene use case list can be ensured by combining the two modes, so that the omission of the scene use cases is avoided. Specifically, in a forward mode, first dimension division is performed on vehicle historical data, wherein first dimension division can be performed according to a vehicle state, second dimension division is performed according to the principle that a user uses a vehicle time axis/space position and the like, then target attributes of scene elements are extracted according to needs, data corresponding to the target attributes are extracted from each dimension to obtain a plurality of scene elements, then scene use cases are generated, user requirements and functional requirements are obtained by analyzing the scene use cases, and in order to facilitate management of the scene use cases, the scene use cases need to be managed in a grading mode and are associated to a scene use case list. In the reverse mode, the existing vehicle functions are analyzed to obtain the used scenes, then the scene use cases corresponding to the existing functions are obtained through item-by-item verification of all dimensions, and the scene use cases are perfected into a scene use case list.
