The application discloses a functional safety monitoring method and device of a vehicle, the vehicle, and a storage medium. The vehicle comprises a service-oriented SOA architecture, and the SOA architecture comprises a main function service layer, a functional safety service layer, and a function abstraction service layer. The application comprises the following steps: receiving current scene information, a user request, an intelligent driving request, and a main function service request of the vehicle; determining whether the current scene is a hazard scene, and determining whether the user request or the intelligent driving request is consistent with the main function service request; if the current scene is a hazard scene, and the user request or the intelligent driving request is inconsistent with the main function service request, then determining whether the user request or the intelligent driving request is consistent with the main function service request within a maximum allowed fault time; and if the user request or the intelligent driving request is consistent with the main function service request, then transmitting the main function service request to the function abstraction service layer. The application solves the problem that software developed based on the SOA architecture cannot meet functional safety level requirements, and enables the whole vehicle to reach a safe state and a safety target.

This invention proposes a service-oriented architecture (SOA) braking system, braking method, computer program product, and vehicle. The braking system includes a controller, a state machine, and a brake actuator. The state machine is used to acquire SOA braking information sent by an external controller, switch the braking state corresponding to the SOA braking information, and store the braking control quantity in the SOA braking information into a state register corresponding to the braking state. The controller is used to read the braking control quantity stored in the corresponding state register according to the braking state indicated by the state machine, and generate a corresponding braking command based on the braking control quantity. The brake actuator is used to perform braking operations based on the braking command.

The application discloses a quality-of-service oriented GPU space-time adaptive resource scheduling method and system, belongs to the field of heterogeneous resource scheduling and management under deep learning inference, and comprises the following steps: determining a minimum SM subset satisfying a quality-of-service constraint and corresponding SM mask configuration in an offline stage; collecting multi-task co-location operation data offline, and constructing an interference-aware delay prediction model by using the multi-task co-location operation data; in an online scheduling stage, when a new task arrives, it is judged whether the GPU is in an idle state according to a current GPU load state; the constructed interference-aware delay prediction model is used for prediction, and it is judged whether the predicted inference delay and the predicted delay both satisfy preset quality-of-service constraints; a time multiplexing strategy is adopted to schedule and execute tasks by intercepting a kernel-level command buffer, and it is ensured that only one task occupies all resources of the GPU at the same time. The application can improve system throughput and guarantee the quality of service of delay-sensitive tasks.

This invention discloses a zero-reconstruction management method for multi-source heterogeneous data based on object indexing. It runs on a dynamic data management platform for a multi-user water resource hybrid game system, with the platform's underlying architecture based on J2EE and SOA (Service-Oriented Architecture). The method includes the following steps: Step S1: Object-oriented abstraction of physical entities involved in water resource management and construction of a three-dimensional data structure model; Step S2: Construction of a fixed core metadata model, replacing database table structure modifications with parameter indexing configuration; Step S3: Construction of a dynamic mapping network between devices and objects under zero-reconstruction, establishing the source and ownership logic of data; Step S4: Receiving multi-source heterogeneous data, decomposing it into its smallest units, and aggregating it into a fixed basic big data table. This method completely breaks through the limitations of traditional business table creation, achieving dynamic management of multi-source heterogeneous data without adding new database tables and fields.

A data science model score database may contain electronic records, each including a data science model identifier and a set of data science model scores. A data science model score server, coupled to the data science model score database, may receive (from a remote user device) an indication of a selected data science model. The server may then retrieve, from the data science score database, information about the selected data science model. Based on the retrieved information, the server may automatically calculate a maturity score for the selected data science model in accordance with a scalable score, a service-oriented score, a validated score, and a productized score. When the server receives from the remote user device an adjustment to at least one of the scalable score, the service-oriented score, the validated score, and the productized score, it may automatically re-calculate the maturity score for the selected data science model.

The application discloses a service-oriented vehicle-mounted diagnosis safe communication method and device, a vehicle and a storage medium. The method comprises the following steps: receiving an identity authentication request sent by a diagnosis client, performing identity verification on the diagnosis client based on the identity authentication request; generating an authentication code and returning the authentication code to the diagnosis client in the case that the identity verification is passed; receiving a token application request carrying the authentication code sent by the diagnosis client, and performing verification on the authentication code; generating and signing an access token in the case that the authentication code verification is passed, and issuing the access token to the diagnosis client, so that the diagnosis client initiates diagnosis resource access to the diagnosis server based on the access token. The technical scheme can improve the communication security of the service-oriented vehicle-mounted diagnosis.

A vehicle communication network with a service oriented architecture (SOA) includes a primary computing device designated for device authorization operations, a zone computing device in signal communication with the primary computing device via the communication network, and a plurality of edge devices in signal communication with the zone computing device and / or the primary computing device via the communication network. The primary computing device is configured to perform device authorization operations, including, receive broadcasted IDs from each of the edge devices, build / update a manifest of the plurality of edge devices based on the broadcasted IDs, reference the manifest and a list of authorized devices that are authorized to operate on the vehicle communication network, to thereby identify one or more unauthorized devices on the vehicle communication network, and prevent operation of the one or more unauthorized devices.

This disclosure provides a software upgrade method, system, in-vehicle infotainment system, storage medium, and program product, relating to the field of in-vehicle software upgrade technology. The method is applied to the local service layer of an in-vehicle Android operating system. The method includes: the in-vehicle infotainment system upgrade management module of the local service layer receiving a software upgrade notification message; and the in-vehicle infotainment system upgrade management module, in response to determining and executing a software upgrade task corresponding to the software upgrade notification message, triggering the vehicle hardware abstraction layer module of the local service layer to execute the software upgrade task through a first service-oriented extensible middleware SOME / IP communication interface based on Internet Protocol. This method can improve the cross-platform compatibility of the software upgrade solution, and by effectively separating the flow logic of the software upgrade state controlled by the in-vehicle infotainment system upgrade management module from the specific execution of the software upgrade task controlled by the vehicle HAL module, it can improve the portability of the solution implementation.
